Description

A kind of paper making additive
Technical field
The present invention relates to pulp technology for making paper, particularly relate to a kind of paper making additive.
Background technology
The great invention of of Zhi Shi Han nationality working people, one of ancient Chinese four inventions, papermaking technology and compass, gunpowder, typography together, provides the basis of material technology to the prosperity of ancient Chinese culture.The invention of paper finishes the history that letter in ancient times wooden tablets or slips for writing is complicated, has greatly facilitated propagation and the development of culture.Papermaking technology is accumulation and the crystallization of wisdom of Han nationality's working people's protracted experience, for writing, prints, paints or the sheet-like fiber goods of packaging etc..Tianshui city is put the Western Han Dynastry unearthed for Ma Tan and is painted with the paper of map, is to find paper the earliest in the world at present.
The production of general printing paper is divided into slurrying and two basic processes of papermaking, and slurrying is exactly the method with machinery, the method for chemistry or method that both combine dissociates plant fiber material and becomes true qualities paper pulp or bleached pulp.Papermaking is then the paper pulp fiber being suspended in water, is combined into the paper in accordance with various requirement through various processing.Enough raw materials with 4～6 months typically need to be stored in paper mill, makes raw material through natural fermentation in storage, is beneficial to slurrying, ensures the continuous production of paper plant simultaneously.Through material papering section, the raw materials such as phragmites communis, wheat straw and timber are cut into tablet (for producing chemical pulp) or wood disconnected (for producing ground wood pulp), chemical liquid is added in less tablet raw material being put into boiling vessel, steaming and decocting is carried out with steam, raw material is cooked into paper pulp, or wood forfeited on mill, wear into paper pulp, it is possible to regrind into paper pulp through a certain degree of steaming and decocting.Then with a large amount of clear water, paper pulp is washed, and by screening and purification, thick sheet, knot, stone and the sand in slurry etc. is removed.Further according to the requirement of paper kind, with bleach, paper pulp is floated to required whiteness, pulls an oar followed by beating equipment.Then add in paper pulp and improve the various adjuvants such as the filler of paper performance, sizing material, sizing agent, and again purify and screen, finally serve paper machine to batch through wet end drainage, press dewatering, cylinder dried, press polish, and carry out cutting and rewinding or cut and produce roll web and sheet paper.If producing coated printing paper to be produced, then realize through coating waste water after needing to be dried middle part or produce into roll web.Outside divided by upper basic process, also include some supporting processes, such as the preparation of cooking liquor, the preparation of bleaching liquor, the boiling and the recovery etc. of chemical drugs in cooking waste liquor and waste gas and heat energy of sizing material.

Primary raw material used by the present invention:
Carboxymethyl cellulose: native cellulose is to be distributed polysaccharide the widest, that content is most in nature, originates the abundantest.The modification technology of current fibre element is concentrated mainly on etherificate and esterification two aspects.Carboxymethylation reaction is the one of etherification technology.Cellulose obtains carboxymethyl cellulose (CMC) after carboxy methylation; its aqueous solution has the effects such as thickening, film forming, gluing, water tariff collection, colloid protection, emulsifying and suspension; it is widely used in the industries such as oil, food, medicine, textile and paper, is one of most important cellulose ethers.
Nano silicon: nano silicon is a kind of inorganic chemical industry material, is commonly called as white carbon.Owing to being ultrafine nanometer, size range, at 1-100nm, therefore has much unique character, as having anti-ultraviolet optical property, can improve other materials aging resistance, intensity and chemical-resistance.Purposes is widely.Nanometer grade silica is amorphous white powder, nontoxic, tasteless, pollution-free, and micro structure is spherical, is SiO in cotton-shaped and netted quasi-grain structure, molecular formula and structural formula2, water insoluble.
Borax: Borax, the decahydrate of sodium tetraborate, molecular formula Na2B4O7·10H2O, is very important containing boron mineral and boron compound.Usually the white powder containing clear crystal, soluble in water.Borax has been widely used, and can be used as cleaning agent, cosmetics, insecticide it can also be used to configure buffer solution and produce other boron compounds etc..
Calcium stearate: white powder, water insoluble, cold ethanol and ether, it is dissolved in the organic solvents such as hot benzene, benzene and Oleum Terebinthinae, is slightly soluble in ethanol and the ether of heat.It is heated to when 400 DEG C slowly decomposing, flammable, meet strong acid and be decomposed into stearic acid and corresponding calcium salt, have hygroscopicity.Purposes: make heat stabilizer and the lubricant of multiple plastic processing, the releasing agent etc. of polrvinyl chloride.In hard product, coordinate with base lead salt, lead soap and can improve gelation speed.It is also used for packaging for foodstuff, medical apparatus etc. and requires nontoxic flexible film and utensil.Also can make polyethylene, polyacrylic halogen-absorber, to eliminate residual catalyst to color and the harmful effect of stability.In rubber processing, make plasticizer, natural rubber and synthetic rubber can be made to soften, and on sulfuration almost without impact.Also act as the lubricant of polyolefine fiber and moulding compound, the intensifier of grease, the waterproofing agent of textile, the flatting agent of paint, manufacture the plasticizer etc. during plastic disc.It is also used in pencil-lead to produce and in medicine, perfume industry.
