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.

2, processing technology

The calcium carbonate, then extracted Limestone ore ground into high calcium 1500-2500 purpose super fine powder, followed by the second procedure, will add the modified caco3 85% 15% additive.it masterbatch, finally through extrusion blown film equipment made into paper or bag.

Three, application field

Stone paper can be applied to one-off living consumption things, such as shopping bags, garbage bags, profession and close-grained bags and boxes, feet set of gloves, tablecloth, raincoat, dust-proof covers etc; Also can be used in cultural printing paper, paper, such as writing pad, advertising and decorating paper, DaoLinZhi, coated paper, membrane papermaking, drawing paper, poster paper, typing paper, mail seal paper, cigarette paper, lattice rahim paper, newspapers, etc.; Can also be used in building decoration, such as decorative wallpaper, etc.; Can also be used in industrial packaging and other fields, such as fertilizer bags, cement bags, rice and flour bag and clothes bag, all kinds of handbags, paper carton boxes, etc.; Can also be used in special paper, such as outdoor working paper, underwater operations under paper, paper, military operation ore special paper, etc. Can say application field is very wide, and as stone papermaking technology continues to mature and upgrades, application field will also bigger.

4, stone, papermaking and ordinary fiber paper compared with the following features:

(1) need not use wood paper (no wood pulp and plant fiber), no cut down trees (currently, each production a ton of paper need cut 25 trees), effective protection of human ecological environment;

(2) the papermaking process doesn't need water (traditional papermaking every production needs 10 - ton paper 100 tons of water); Effective saving a valuable resource in papermaking, cuts in the process of wastewater treatment process and cost, greatly reduced the cost of production; papermaking

(3) the papermaking process without steam boiler; Very good reduces the production investment, reduce production cost and improve the production safety;

(4) the papermaking process doesn't need without add acid, alkali, need not bleach, with gas, not discharge sewage not discharge air pollution, water pollution not; So it won't environment cause environmental pollution and harm, also need not production purification program;

(5) production site covers an area of an area small, production environment clean, the production cost is reduced, production management simplified;

(6) inexhaustible cheap raw materials, let production obtains safeguard, let your profits more lucrative;

(7) simple production process, fully automatic production line. Can let the product diversification, manufacturing automation, management more simple.

5, equipment recommend

Dawn HGM dhi production three-ring micro powder mill is the present domestic 1,500 eye - 3000 mesh super fine powder production technology is the most advanced, yield the biggest grinding equipment, currently in Indonesia in the production line of "stone paper" put into production, equipment operation is good. Specific technical characteristics as follows:

(1) high efficiency and low energy consumption. In the material, power, final fineness the same circumstances, jet mill and mixing mill than the high output 40%. Can satisfy the papermaking of calcium carbonate rocks in great demand, so as to improve the paper quantity.

(2) adopt totally closed device and finishing technology improve the fine powder, guarantee the accuracy of papermaking of high quality.

(3) in the wear parts, service life than impact grinder and turbine crushing can prolong above 1 years;

(4) the mill chamber without rolling bearing and bolt. Does not exist bearing and seal and delicate destroy machine screw off yi song.

Dawn to promote stone paper dhi production, vigorously developed a series of papermaking technology with stone mill, grinding machine, besides three-ring turned in there: trapezoid grinding mill, new Raymond milling machine, high-pressure suspended roller grinding machine, high-pressure micro powder grinding machine, etc, this series of mill grind out completely can achieve stone to micron granularity, equivalent to the wider thousandth, complete with papermaking requirements. 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.
