Environmental protection stone paper processing of Liming HGM series ring roller micro powder mill

On January 26, 2010, the State Council Information Office released a new environmentally friendly paper technology "stone paper" that can replace plant fibers and is made from rich ores, which is a major breakthrough in the field of traditional paper making and packaging materials. Let's take a look at the environmental protection "stone paper".

1. Technology Introduction

Stone paper technology, is the most abundant mineral resources in the earth's crust calcium carbonate as the main raw material, polymer materials and a variety of inorganic materials as auxiliary raw materials, the use of polymer interface chemistry and filler modification technology, a reversible recycling by a special process, with modern technology characteristics of the new paper technology. Stone paper technology, is the world's advanced new technology. The birth of this technology, both to solve the traditional paper pollution to the environment brought harm to the problem, but also to solve a large number of plastic packaging use caused by white pollution and a large number of oil resources wasted.

2. Processing technology

Extract the calcium carbonate from limestone, then grind the ore into high calcium 1500-2500 mesh ultra-fine powder, followed by the second process, 85% modified calcium carbonate with 15% additive to make masterbatch, and finally made into paper or bags by extrusion blown film equipment.

3. Application areas

Stone paper can be used in disposable consumables, such as garbage bags, shopping bags, food bags, dense bags, lunch boxes, tablecloths, raincoats, dust covers, etc.; it can also be used in cultural paper, such as printing paper, writing paper, advertising decorative paper, Dowling paper, coated paper, film paper, drawing paper, poster paper, typing paper, postal seal paper, cigarette paper, Grassian paper, newsprint, etc.; it can also be used in building materials decoration, such as It can also be used in industrial packaging, such as fertilizer bags, cement bags, rice and flour bags, garment bags, various handbags, cartons, etc. It can also be used in special paper, such as field work paper, underwater work paper, mining work paper, military special paper, etc. It can be said that the application field is very wide, and with the continuous maturity and upgrade of stone paper technology, the application field will be even greater.

4. “Stone paper”and ordinary fiber paper compared to the following characteristics:

(1) No need to use wood to make paper (no wood pulp and plant fiber), no more cutting down woods (at present, each ton of paper production needs to cut down 25 trees), effective protection of the human ecological environment;

(2) The paper-making process does not require water (traditional paper production requires 10-100 tons of water per ton of paper); effectively saving valuable water resources, eliminating the need for sewage treatment links and costs in the paper-making process, greatly reducing the production costs of paper;

(3) the papermaking process without steam boilers; well reduce the production investment, reduce production costs and improve the safety of production;

(4) the papermaking process without adding acid, without adding alkali, without bleaching, without exhaust gas, without sewage, without polluting the air, polluting water; so that the environment will not cause environmental pollution and harm, but also without production purification procedures;

(5) The production site covers a small area, the production environment is clean, production costs are reduced, and production management is simplified;

(6) inexhaustible cheap raw materials, so that production is guaranteed, so that profits are more lucrative;

(7) Simple production process, fully automatic production line. It can make the product diversification, production automation and simpler management.

5. Equipment recommendation

MW series ring roller micro powder mill produced by OCP Machinery is the most advanced technology and the largest output grinding equipment in the production of superfine powder from 1500 mesh to 3000 mesh in China. Specific technical characteristics are as follows:

(1) High efficiency and low consumption. Under the same fineness and power consumption, it has lower investment cost and shorter recovery period than airflow mill, but the output is more than 45% higher.

(2) Low loss and high fineness. Wear-resistant parts are made of high-quality wear-resistant materials, with a service life of more than one year, and the final fineness of the finished product can reach D97≤5μm at one time.

(3) Safe, reliable and environmental protection. No rolling bearings and screws in the grinding cavity, avoiding the problem of easy loss of bearings, screws loose and destroy the equipment. Adopt high efficiency pulse type dust collector, configured with silencer and muffler room, which reduces dust and noise pollution and has excellent environmental protection effect.
