At the Copenhagen climate conference in environmental protection, the world's hot environmental protection, strengthen environmental protection, China vigorously advocates the great situation of new environmental protection material, environmental protection "stone paper" along the way. On January 26, 2010, the state council information office issued an alternative plant fiber, drawn from rich ore new green environmental protection "stone paper" paper technology; On March 2, 2010, environmental protection "stone paper" in the great hall of the people at the two sessions, "it is a breakthrough in the field of traditional paper and packaging materials. Let us together to understand environmental protection" stone paper ":

1. The technology introduction
Stone paper, new technology is based on the earth's crust is the most abundant mineral resources within the calcium carbonate as the main raw material, with high polymer material and a variety of inorganic matter as auxiliary materials, using the polymer interface chemistry principle and filling modification technology, through the special craft processing and become a reversible recycling, have the characteristics of the modern technology of new type of paper-making technology. Stone paper technology, is a domestic leading the world's advanced technologies. The birth of the technology, not only solved the traditional papermaking pollution damage to the environment problem, and solved a lot of white pollution caused by the use of plastic packing materials and waste a lot of oil resources.
2. The processing technology
Extract the calcium carbonate in the limestone, and then grinding ore into high calcium purpose of ultrafine powder, 1500-2500, then a second process, adding 15% 85% of modified calcium carbonate additives masterbatch, finally through extrusion blown film equipment made of paper or bag.
3. The application field
Stone paper can be applied to a one-time life consumption goods, such as garbage bags, shopping bag, food bag, dense bags, boxes, table cloth, raincoat, dust cover and so on; Of culture are available, such as printing paper, writing paper, advertising, packaging paper, woodfree printing paper, coated paper, film paper, art paper, advertising paper, paper, mail letters, gration paper, newsprint paper, cigarette paper, etc.; Can also be used in building decoration, such as decorative wallpaper, etc.; Can also be applied to the industrial packaging and other fields, such as fertilizer bags, cement bags, flour bags, clothing bags, all kinds of handbags, paper carton etc.; Can also be applied to special paper, paper, underwater operation paper, such as field operations under the homework paper, military special paper, etc. To say the application field is very broad, and as stone paper technology matures and upgrade, applications will also be greater.
4. The stone paper compared with the ordinary fiber paper has the following features:
(1) no need to use wood paper (no wood pulp and plant fiber), not cut down the trees (currently, each producing one ton of paper need to cut down trees 25), the effective protection of human ecological environment;
(2) the papermaking process without water (traditional paper every tons of paper production needs 10-100 tons of water). Effective save precious water resources, the reduction in the process of papermaking wastewater treatment process and cost, greatly reduced the production cost of paper;
(3) the papermaking process without steam boiler; Very good to reduce the production investment, reduces the production cost and improve the production safety;
(4) the papermaking process without adding acid, alkaline, without bleaching, exhaust waste gas, sewage, will not pollute the air and water pollution; So it would not cause any environmental pollution and environmental harm, at the same time also need not produce purification procedures;
(5) production area cover an area of an area small, clean production environment, reduce the production cost, simplify the production management;
(6) as cheap raw materials for production are guaranteed to make more profitable;
(7) simple production process, fully automated production line. Can let the product diversification, production automation, management is more simple.

5. Equipment recommended
Dawn heavy HGM series micro ring roller grinding is the present domestic 1500 mesh, 1500 mesh in the production of ultrafine powder technology the most advanced, the largest output grinding equipment. The specific technical characteristics are as follows:
(1) efficient low consumption. Under the same product fineness and power, than a jet mill low investment cost, short recovery period, but the high output of more than 45%.
(2) low loss high fineness. Parts adopt high quality wear-resistant materials, service life in more than one year more, final fineness of one-time can reach D97 5 microns or less.
(3) safe and reliable environment. Grinding cavity no rolling bearing and screw, to avoid the bearing damage, the equipment from the damage of screw loosening. By high impulse type dust catcher, equipped with muffler and quieter room, reduced the dust and noise pollution, environmental protection excellent results.
