Analytical artificially impact production line technique development

In recent years, in our artificially impact processing got increasingly widely. stone production line is mainly composed of vibrating feeder, jaw, impactor, making pressure-blasting machine, vibrating screen and belt conveyor, washing sand machine etc equipment composition. Our artificially sand production technology development can be roughly divided into three stages: groping stage, mature stage and constant innovation of wide application stage.

Our artificially impact application the beginning in the 1960s the construction of MaoTiaoHe hydropower station at the beginning of guizhou, the poor performance of the production of artificial sand hammer crusher, and on a smaller scale. 65 years yingxiuwan project built production capacity for 160t/h artificial sand system (hereinafter referred to as "artificially sand system"), Slate then pulled open our artificial stone production technology research, application prologue.

At that time, in the domestic production of artificial impact and application is still in the blank, how to artificially sand system of technological process design, equipment selection and how to improve the sand product quality and reduce production costs, etc, it is to should be in the practice exploration problems, artificially sand technology research into a lengthy exploration stage, this one phase continue supremacy in the late 1980's. During this period, a large artificially sand system mainly have wujiangdu, manwan and five strong creek sand system, etc.

After nearly 20 years of exploration, artificial sand technology has made some achievements, but still not mature, especially system design still exist many defects, such as process design USES a single fixed mode: spinning back the crushing crusher, cone crusher finely mainly adopts; Rod milling machine wet sand etc, finished materials of the gradation adjust ability is not strong. On the other hand, after this period production practice, the various try, gradually solved practical encountered many technical problems, such as granite and quartzite contour SiO2 content of equipment supra-normal wear rock for our country and more extensively applied artificially impact established, accumulated experience.

After the nineties, accelerate hydropower development, the xiaolangdi, Sandstone, ertan, three gorges, batch of oversize dachaoshan, vladimir construction of hydropower project, the mature for artificial sand technology provides a golden opportunity. Xiaolangdi project even the land sand system, design processing ability after 700t/h (1000t/h) expanded reach for LiaoYuan quartz sandstone, the average level HeLuanShi, SiO2 is 76%, highest compressive strength of domestic 351MPa, globe already built engineering material of impact the hardest of processing for processing equipment, the abrasion serious. But because the system adopted international famous manufacturer henan dawn heavy industry technology Co., LTD specializing in xiaolangdi this hard broken Limestone design sand blasting equipment, grinding according to different particle size adopt different crushing equipment to multistage crush, and adopts the flexible production technology arbitrary cycle, not only ensure the normal running of the system, and create the 595h peak average monthly running time the country's highest record.

Stone product maintenance

stone as a building and decoration dual efficacy with the natural building materials, have been favored by people. People chose stone, in addition to its architectural function, but also in the natural decorative beauty favored it. Granite uniform tonal and fortitude wear-resisting texture, marble downy elegant color and natural and pure and fresh texture, beautify our living environment, make we fully felt natural beauty and charm. Stone carvings as art gallery in resplendent pearl of China has a long history of ancient times, not only left us many rocky historical artifacts, more important is through the stone carving works left a large amount of historical culture. Modern processing and mining equipment makes this art more carry forward, stone art types and levels have unprecedented development. As a kind of stone products, as a large number of the development and application of some problems about stone produce also show diversification and complicated. Therefore, how to scientifically stone goods to the late prophase preventative treatment and cleaning and marble, how will the artwork is long-term preservation and always put a glorious, more and more attention.

Stone material is product of nature, also is a kind of mineral object, its inevitable will be some congenital defects. It exists in nature can appear a few lesions, it applied to people's living environment difficult to avoid after by various pollution and human damage. If the stone pollute and damage by disposal method than or improper handling, it will make the application effect of the stone discount, but also affects the use environment beautification the stone, but also will thus atmosphere of some economic loss and jointly and severally economic disputes and other social problems appear. Therefore, correctly understanding stone, a knowledge of the various of stone material Sandstone, master correct stone protection, cleaning and nursing method is people keep the stone to brilliant color and pure and fresh and environmental premise and necessary.

Six recruit to teach you how to identify inferior man-made stone

As man-made stone market continues to expand, and national relevant quality standards come on stage, now have continued in the national brand products man-made stone increase gradually, fake also emerge in endlessly. One is counterfeit famous brand, some manufacturer of consumer products, using joint in the market didn't know that famous brand, through with gray, faked anti-counterfeiting fenma masquerading as genuine. Using the manufacturers market management with the warranty card not to be lax, to customers or don't stick anti-counterfeiting, gold measures to achieve deceive such purpose; One is directly for the use of consumers and elsewhere on the cheap psychology, local horse, some illegal manufacturer in indigenous product quality doesn't pass the circumstance, with industrial resin instead of methyl methacrylate, instead of aluminum hydroxide with calcium carbonate, with extremely low price shock market. Now in the market retail every meters of man-made stone more than 300 yuan, this kind of products are mostly so without any quality and after-sale guarantee, extremely easy rupture, deformation, faded, even poisonous.

Another impede man-made stone material use factor is one factor. Because of man-made stone production process difference, properties, characteristics are not wholly consistent, so the above advantages does not settle is you purchase the man-made stone performance. Currently imports of man-made stone on the market in performance is better. Such as imports of man-made stone permission to use sand paper burnish surface scratches, users themselves to handle it will no longer, and many domestic across the man-made stone apparently no, the burnish more lousy. The choose and buy man-made stone, you'd better take a board to undertake ELieXing test, for example pour soy sauce or grease and Merle loss trials.

Quality goods: generally have ISO series international quality system authentication and related inspection report, using pure methyl propylene methyl ester and aluminum hydroxide as raw materials, avirulent insipidity, workability, not break, USES high-grade or import pigment, visual color pure, natural, simple sense, large import equipment assembly line production, stable quality, batch off color, material particle is exquisite, smaller hand have silk feeling, ultraviolet radiation resistant performance is good, period use do not fade, have standard marketing network, service assurance, products are anti-counterfeiting mark, maintenance manuals and product quality assurance, 10 years to 15 years quality guarantee commitments, the market price -- in 350 yuan RMB 800 meters, some importing man-made stone prices higher.

Inferior product: using low industrial resin and calcium carbonate as raw materials, toxic have peculiar smell, poor, easy to be broken deformation processing, the pigment, visual color muddy low-grade faded, the surface has plastic glial feeling, small equipment or soil equipment primarily, quality is not stable, batch color, material granules, hands have large, good resistance to light rough feel bad, general year or two sex, usually beginning to fade, market prices on shop sales, the general below 350 yuan confusion/rice, in particular, can choose according to the process of tips:

A look: visual sample color pure not cloudy, the surface does not have similar plastic glial feeling, plank opposite without tiny vent.
Two smell: nose smell Slate. Without pungent chemical
Three touch: hand touch sample surface is silk feeling, no acerbity feeling, no obvious rugged feeling.
Four strokes: with his nails, without obvious stroke plate surface scratches.
Five touch: the same two sample mutual percussion, not easy and broken.
Six check: check whether ISO quality system authentication products, quality products, with or without warranty card report and related anti-counterfeiting mark.

How to distinguish between green stone

For market decoration stone materials, how should judge it is green stone? Generally speaking, the easier way basically has: want to see building materials product packing is "Chinese environment mark"; Secondly, to see the product specification specified in the main composition of containing poisonous and harmful substance; whether Three is smell odour asked again if the product by the relevant authorities testing, whether in the security of data within the scope of; After the fourth is touch without burning, inflamed traces and representation.

Stone into natural stone material and man-made stone. Natural stone material is divided into marble, granite and Sandstone, and used in domestic outfit mostly marble. According to former stone association of sichuan province honorary President of the YangXueDong (current) to introduce, according to the national building and the ministry formulated jointly by building industry standard "natural stone products IC518-93 control standard of classification of radioactivity protection in the stone by radioactive than activity into A, B and C, each of three components, and the classification of A and B, C three belong to conform to the standards, just use the stone material of the range. Standard: radioactive than activity relatively small for A kind of stone, its usage scope unrestrained; The relatively high than activity radioactive, except for class B stone fragile for bedroom interior surface outside, all the buildings can be used for other internal and external finishes; Radioactive than activity higher to C stone, only can be used for building outside finishes, seawall, pier and stones, garden iso-effect decoration materials, etc. Therefore, can't generally speaking B, C stone is overweight stone. For consumers how to choose stone, experts say, is to see its quality inspection report, distinguish three stone.

How to maintain decorative stone

Natural stone material after processing can be fine decoration materials, which are both in material processing production, adornment effect and product price etc. All shows its superiority, its natural beauty, color and pattern than other decoration products more unique charm. But stone also need reasonable cleaning and maintenance.

A, do not mess with the neutral cleaner

Stone afraid encounter acid and alkaline strong liquid, clean stone material not for the sake of rapid clean effect ignored cleaning ingredients. General acid and alkaline detergents are contained. So if long time use of unknown components cleaner, will make the stone surface gloss lost everything. In addition, stone on the residue is not neutral reagents in the main produce stone lesions.

Limestone, not optional waxing

Market various different kinds of wax waterborne wax, stearic acid wax, oily wax, acrylic wax etc. These waxes contain acid-base material basically. Not only can jam stone breathing wool stoma, will also touch WuChen form scale, causing the stone surface wax Browning phenomenon.

In the pedestrian and cargo circulation high places must frequency waxing, it must be please professional maintenance company with wax and maintenance guiding the method.

Third, must always keep ventilated dry

Stone afraid environment humidity too big. Hydrosphere of stone material produce hydration, will carbonated hydrolysis and role, produce water spots, whiting, weathering, erosion, rust yellow wait for all sorts of lesions and ruin the stone, therefore installed stone place keep ventilated dry.

Mosaic, to pay attention to choose the protective agent varieties

On the stone shielding after construction must keep stone permeability and waterproof, anti-fouling sex. Do not use untrusted protective agent, lest not only could not reach the protective effect, but increases the difficulty of the stone maintenance.

Fifth, to immediately remove pollution

All stone have natural wool stoma, pollution sources (oil, tea, coffee, coke, soy sauce, ink, etc.) will be very easy to follow wool stoma to infiltrate stone, forming a nasty internal besmirch. Therefore must choose quality stone special protective agent to prevent pollution sources pollution stone. Want to know all the protective agent are impossible to long-term block 100% pollution, so once a pollution source must be stained in stone immediately clean up to prevent infiltration stone wool stoma inside.

Six and thoroughly kept clean Both quality of a material is solid granite (hardness HRs88-1114-7) or the soft texture of marble (hardness HRs46-773-5) are not resistant to wind sand soil particles and the long-term torture. So will often use precipitator or electrostatic mop thoroughly clean dust and work well.

Commercial space entrance best can put dust removal pads, avoid shoes with sand stone, the best introduction to scratch changed after wear slippers, reduce sand dust wear stone material surface.

Seven, to regular maintenance, maintenance luster Light by dusting, clean is unable to make beautiful stone continued luster, and therefore never fading must regularly please professional stone maintenance personnel do maintenance and luster regeneration maintenance work. Such as: use the crystallization liquid let marble surface recrystallization, or use polishing powder let marble or granite reclaimed burnish, or use breathable burnish, all can make cryoprotectants, etc for your stone like new.

Eight, regularly protective processing Want to grow the stone material life, blocking water and pollution sources of penetration, must regularly (depending on the stone types and protective agent quality and decide. It is better to 1 ~ 3 years do 1 ~ 2 times processing) shielding processing.

Nine, not long-term cover carpet, sundry To maintain smooth stone breathing, should avoid on in stone material surface of carpet and sundry, long-term coverage of moisture or stone by stone wool stoma volatility cannot come out. Stone will be overweight, water content for moisture increased produce aggravating stone lesions problem. If you must be laid carpet, piled up sundry, please don't forget to often move.

Marble selection and construction inspection

Marble is divided into natural marble and artificial marble two kinds. Natural marble quality of a material is solid, color two-tone variety, sheen, therefore, there are a variety of form unique natural beauty. Scagliola than natural marble is light weight, high strength, thickness thin, corrosion resistance, fight pollution, have a good workability, can be made into arc, curved surface, construction is convenient. Sandstone in color and texture than natural marble is beautiful, the soft and natural. Limestone, in choice marble decoration materials, should fully consider the integral effect of the imperfect, such as metope, cylinder, ground and so on the different parts; And marble ground tabula rasa have beautiful decorative pattern, such as the cloud of the FeiDu like light cloud patterns, like the natural picture color texture. Marble is widely used for high-grade bathroom, bathroom wash gargle mesa and all kinds of furniture mesa. In choice marble adornment material, to marble surface whether level off, without defect, and presence of crack edges without sand holes, grooves, whether pure tonal aspects, screening.

Anyhow, marble panels, stone quality requirements for high polished close, colour and lustre is beautiful, edges and tidy, surface can not have hidden wounds, weathering, corrosion defects.

Construction craft: laying marble panels, shall be completely eliminated grassroots ash and debris, rinse and dry. Combined with the dry mortar, by layer must mix mortar shall be ripe, avoid by all means, mixing with dilute mortar. Pave mortar cement slurry moist grassroots, brush well after meal, then spread the mortar, combining layers combined layer firm knead flat took mortar shall be. Galley posted before, plate surface should be soaked dried, shop, try again after shop, with official. The localization, will tap compaction uniform plates, are prohibited MianPu dry cement and stick.

Acceptance should focus on the attention MianPu posted whether level off the marble act the role ofing, firm, juncture straight without askew, no stains and plasma mark, the surface is clean, color is harmonious. In addition, still should notice whether empty drum, juncture plate without discretion deviation.

The two most common types of marble nursing methods

The use of stone after accumulating or improper care, make its surface loses natural color, its high temperament, and easy shrugging off not only that shelter evil people and practices, hideous. But after marble nursing method, it can resume after processing the face of original eye shiny. And while the same marble maintenance treatment, make its colourful after maintained. Recommend below two commonly used marble nursing methods.

The first kind of marble protection of preventive protection method, main is to prevent micro bacteria in marble breathing suck stomatal inside. Because the stomata such as marble of human skin, breathing often will the bacterium in air, dust, microbial wait while sucking eight, accumulate over a long period, facilitate marble surface breed micro bacteria and besmirch, make marble lost its natural burnish. While general cleaner can remove marble surface dirt, and marble within the micro bacteria stomata padded with besmirch, if using still cannot remove with acidic strong detergent, will clean marble Limestone surface to outsmart oneself, the depth of the high acidic detergent, and corrosion loses its original luster.

So clean and bright and preventive protection, to launch below the surface of the liquid will marble stomata closed, make micro bacteria can't breed, and the natural luster also this marble can maintain. These provide preventive effectiveness potions have many, mainly with different needs and different types of marble and use of marble, so must have abundant understanding, itself only the appropriate choice. These potions are colorless, odorless, odourless, and waterproof, prevent oil and antifouling performance.

The second approach is marble renovation system. Ten to one hundred years can be a complete revamping the marble of 100 percent. The method is to marble surface grinding damaged parts, granite flat and grinding smooth, make marble restore its natural color and luminosity, applicable to general comparison residual I E3 (or decorate when he scratch, wear, caused by the marble of wound). Because the old than completely renovated, and new save 80% during refinishing engineering, do not affect business, so general hotels, malls, residential are ready to use.

Reading "stone paper"

At present, the international society for environmental protection in China calls for more and more big, also more and more attention to environmental protection, environmental protection "and" stone paper intrade at this time. "On January 26, 2010, the state council information office released a kind of alternative plant fiber, drawn from rich ore of new environmental paper technology environmental protection" stone paper ";" March 2, 2010, environmental protection "stone paper" in the great hall of the people, "it is CPPCC debuted traditional papermaking and packing materials areas of significant breakthrough. Let us together understand environmental protection" stone paper ":

1, technology introduction

Stone paper new technology, is the most abundant crust of mineral resources calcium carbonate as main raw materials, polymer materials and various minerals as auxiliary materials, using polymer interface chemical principle and filling modification technology, with a special processing technology into a reversible recycling, have modern technical characteristics of new type of paper-making technology. Stone paper technology is a leading world advanced new technology. The birth of this technology is settled, the traditional papermaking pollution to the environment, the harm and resolve the problems caused by the use of plastic packaging the white pollution and massive oil resources waste problem.

Stone

The deterioration of the environment, cause the country, the people around the world watch, the stones at papermaking has greatly improved the environment problem and dawn heavy industry technology as ore crushing enterprise moment bright pearl will and stone papermaking go hand in hand, and work together to build a harmonious, peaceful home.

White marble and white differences between comprised

White marble and white comprised may seem very similar, but they have different characteristics, and have different advantages, especially when as kitchen mesa material.

Chemical structure

Although white marble and white sediments in extreme is comprised of under pressure, but marble is formed from Limestone and from the Sandstone is comprised.

Used as mesa

Although white marble as mesa gained popularity, white is more hardness and comprised has better fight corrupt sex.

difference

Buyers at first glance easily confused with white comprised white marble. But careful observation will find, comprised of microscopic particles containing extra.

Hillock stone

Hillock, have very good product adoprs electrocast refractories.through heat-resistance and anti fouling. Hillock product adoprs electrocast refractories.through the li shi, such as, white or color mixed, and AggloSimplex quartz MargheStone and other products, is to use white or color marble.

Traditional choice

Although white marble than white comprised is more likely to contain stain and Nick, the baker often also choose white marble mesa, because marble mesa appearance more show beautiful and easy.

Compared with limestone cave stone

Hole of stone and Limestone quite similar chemical composition in structure and form, but also have obvious difference. The two types of stone often used in construction and decoration.

limestone

The limestone is a kind of sedimentary rock composed by calcite, it is more. It with the passage of time be water dissolved, cause caves or other forms.

Hole stone

Hole stone is a type of limestone, is dissolved by water in limestone formed after the recrystallization. More light than limestone cave stone more porous.

sedimentary

Sedimentary rocks by chemicals, silt is, decay of plants and animals, such as holes formed stone and limestone. The formation process of limestone than hole stone slow, in some degree stalactites and stalagmites similar.

history

Lime hua and limestone are used in architecture. Limestone, because heavy so often used in cylinder and cornerstone. Hole stone, especially the more light lime hua, often used in Roman architecture.

function

Hole stone and limestone are now commonly used household adornment, especially the sink and mesa. The two are relatively cheap, and durable, color and style is varied.

Sandstone stone conservation note "five not"

(1) shall not directly wash with water

Natural stone material and natural lumber is same, will breathe a porous material, it is easy to absorb moisture, or through the water dissolved and intrusive pollution. Sandstone stone if absorb excessive moisture and pollution, inevitably will cause disease, such as: sandstone stone, fall off, split, weathering degree, vomit yellow, water spot and pitting, BaiHua, fog face annoying problem. So should avoid rinse with water or through the wet mop wash sandstone stone material surface.

(2) do not contact the neutral items

All are afraid of acid and alkali stone. For example: acid often cause granite pyrite oxidation and produce that spit yellow phenomenon, acid will resolve marble contain calcium carbonate, cause surface erosion of status, alkali would also erode granite of silicon carbide crystal mineral feldspar and quartz grain boundaries cause of the phenomenon of grain detachment. Therefore the neutral item is destroyed the reasons stone mirror.

(3) shall not take on wax

Market various different kinds of wax waterborne la, feeling fatty acid la, oily wax, acrylic la etc. These la basically all contain acid-base substances. Not only can jam stone breathing wool stoma, will also touch WuChen scale, cause sandstone formation wax produced stone material surface analysis phenomena. If the pedestrian circulation frequency high places must, when they must on wax professional maintenance company, please. With wax and maintenance instruction

(4) do not mess with the neutral cleaner

For the sake of quickly clean effect, general acid and alkaline cleaning all contains a long time, so if the use of unknown components cleaner, will make the sandstone stone material surface gloss lost everything, and because of the neutral reagents residue is produced after the main stone lesions.

(5) not long-term cover carpet, sundry

To maintain smooth stone, should avoid breathing in sandstone stone material surface of carpet and sundry, long-term coverage or stone by stone wool stoma moisture cannot come out, the stone will be volatile overweight, water content for moisture increased produce aggravating stone lesions issues such as you must laying carpet, piled up sundry, please don't forget to often changed thoroughly kept clean.

So sometimes using dust catcher and electrostatic mop thoroughly clean dust and work well.

Commercial space can be put ChuSha pad at the entrance to the best

The shoes with sand filter. Homes best introductory changed after wear slippers, reduce sand dust wear the opportunity of stone material surface. Want to periodically maintain, maintenance burnish, dusting and cleaning is unable to make beautiful stone burnish keep continuing the back. Therefore must regularly please send someone do professional company of maintenance and luster regeneration maintenance work.
