Introduction:
PVA is the raw material of producing the synthetic vinylon . The full name of it is Polyvinyl Alcohol. It is a kind of white powder ,flake or flocculent solid, and it is odorless. And it is also a kind of organic compounds, it can be soluble in water, but is insoluble in gasoline, kerosene, oil, benzene, toluene, dichloroethane, carbon tetrachloride, acetone, ethyl acetate, methanol and ethylene glycol etc, and slightly soluble in dimethyl sulfoxide. It is non-toxic, non-irritating to the skin, and will not cause skin allergies, but the dust of it has a stimulating effect on the eyes. It is hazardous to health if inhaled, ingested or absorbed through the skin. It is flammable and irritating. It should be stored in ventilated, cool and dry place, keep away from the source of ignition. You must be gently to prevent damage to the packaging during the transportation.
Application:
The application of polyvinyl alcohol is very wide.
1. vinylon material: polyvinyl alcohol can obtained the vinylon fibers sfter dissolution, spinning and the treatment of acetalization, we can obtained the vinylon textiles after blending with cotton, wool, viscose fiber, and it is widely used in clothes, cord, rope nets and so on.
2. polyvinyl alcohol-based modulation of the slurry has a good adhesion of cotton, line, polyester ans polyvinyl alcohol viscose fibers, after the film clean,it is smooth, strong and can resistant both to promote fitness warp weave,reduce warp friction and blending during the weaving process,the warp breakage caused by stretching and other intense exercise, reduces the breakage rate of the loom, and weave fabric feel smooth and delicate, the cloth not rough.
3. polyvinyl alcohol is a kind of water-soluble polymer, it is very convenient to mixing, sizing and desizing. The general election low average degree of polymerization of polyvinyl alcohol as a slurry is good(such as PVA15-99,16-99,17-99).
4. aqueous solution of polyvinyl alcohol has a strong adhesion of the materials containing a cellulose (such as paper, cloth, wood and so on). With the advantage of safe and non-toxic, it can be used for laminated cardboard,corrugated board and office adhesive glue. To pack the weight such as cement,fertilizer, grain and so on with brown paper bags can also use PVA as a binder.
5. polyvinyl alcohol can be used as the paper surface sizing agent in the paper industry,and has the characteristics of having good film, film strength that can improve the paper printability, smoothness,abrasion resistance, folding endurance,oil resistance and chemical resistance.
6. can improve the whiteness and gloss of the paper, and the print gloss, bright color, the improve the quality of the paper. It better to select high average degree of polymerization of polyvinyl alcohol as well. It can also be used as the internal sizing agent of paper, adding powdered polyvinyl alcohol along with paper pulp to beat and papermaking,the paper strength thus obtained is high.
Marker quotation:
As people increasingly attention of environmental protection, plastic use "white pollution" to the environment after the attention of the world, therefore, capable of biodegradable material obtained the vigorous development. Polyvinyl alcohol film has excellent performance of microbial decomposition, can be decomposed into carbon dioxide and water, do not pollute the environment, but also has some unique properties. Such as: gas barrier properties , transparency, anti-static, toughness, resistance to organic solvents, water-soluble and so on, to meet the various sectors of the film 's various demands, and therefore caused the development and application of domestic boom.
