Description
Technical field
The present invention relates to a kind of production method and flow process of paper, be specifically related to a kind of method and flow process of stone water-free paper-making, belong to the synthetic paper production technical field.
Background technology
Paper and paperboard products are the consumer goods indispensable during people live, and the production of paper at present mainly is to utilize fibre resources such as timber, produces paper pulp by the method for physics, chemistry, and further processing obtains goods such as paper and cardboard.Generally comprise multiple chemical treatments and mechanical processes in the middle of this, not only need a large amount of energy and water resource, the waste water of generation, waste gas etc. pollute also comparatively serious.For example chemical pulping need pass through processes such as raw material washing, boiling, bleaching, copies that paper will add then that various chemical agents join that slurry, stream send, drying etc., also needs chemicals to carry out the coating on surface sometimes.Whole process is comparatively complicated, easily produces multiple refuse, contains a large amount of organic pollutions in the waste liquid of boiling, and is very harmful to water body; Easily producing multiple noxious material in traditional bleaching---organohalogen compounds, encircle biphenyl etc., therefore traditional paper industry has considerable influence to environment more, and paper making equipment has high input technological process complexity, cost height simultaneously.
China's paper industry increased rapidly in recent years, but lack of raw materials has seriously restricted industry development.5,930 ten thousand tons of domestic paper in 2008 and cardboard consumption figures, than prior year growth by 9.03%, year consumption figure is 45 kilograms per capita, and near world average level (50 kilograms per capita of every year), comparing developed country's year pre-capita consumption paper such as flourishing America and Europe, Japan and cardboard has gap greatly for 200 kilograms.China's Forest Resources is poor relatively, and limited land resources can't provide enough wood supplies, and paper making raw material is based on careless class and waste paper etc., and careless class pulping sewage is administered and thoroughly do not solved as yet, product that can't the production better quality.China's waste paper reclaims and does not also form rounded system, and paper industry mainly relies on import with waste paper, but the recycle of waste paper demand sharp increase in recent years, developed country's pay attention to day by day fibre resources makes the imported waste paper price soaring again and again.Serious threat that there is lack of raw materials tradition paper industry.
In order to have breakthrough on problems such as environmental protection and industry development, global scientific and technological circle, business circles all research and develop from the direction of no natural fabric, and wherein, utilizing stone and plastic synthetic paper is exactly the new life's in this field developing direction.Nineteen sixty-five, macromolecule is two-way to draw (prolonging) to stretch the Study on Technology success, has laid good technology basis for producing synthetic paper especially.
Synthetic paper is a main raw material with stone (calcium carbonate) and macromolecule resin (polyethylene, polypropylene etc.), can adopt rolling process, The tape casting, blown film method or biaxial tension method to produce, become that paper has that intensity is big, anti tear, anti-perforation, wear-resisting folding are folded, humidity, anti-characteristics such as damage by worms.Because of its special raw material and preparation technology, synthetic paper has more extensive use and outstanding advantage than common paper, makes it be specially adapted to open-air outdoor exploitation as the good WATER RESISTANCE of synthetic paper; Because the dust of not giving birth to of synthetic paper does not fall hair, and it can be used at dust free room; Synthetic paper can directly contact with food; Superior processing characteristics can adopt and cut, cross cutting, embossing, gold stamping, boring, heat are folding, splicing etc. returned construction methods.In addition, synthetic paper adopts anhydrous production in process of production, compares to traditional papermaking, has avoided the papermaking wastewater sludge handling process, helps environmental protection; Simultaneously, the synthetic paper product is recyclable to be utilized again, even also can not produced toxic gas by burning disposal, causes secondary pollution, meets modern environmental protection requirement.As seen, synthetic paper is the development trend of present traditional paper substitute.
The main production method of synthetic paper has rolling process, The tape casting, blown film method, biaxial tension method.Main manufacturer has Japanese prince You Bo (YVPO), TaiWan, China platform to mould South Asia (NANYA), French Puli Asia etc.Starting late of domestic synthetic paper only has enterprise of a few family to produce, and quality is relatively poor relatively, and the quality of product is less stable also, has influenced its development.
