Product Description It has good solubility, film formation, adhesive property, thermal stability, solvent resistance and reactivity.The appearance is white or slightly yellow particles or powder, it is a kind of water soluble enviromental protection polymer with a wide range of uses and its performation is between plastic and rubberProduct DescriptionPolyvinyl alcohol is an organic compound with the chemical formula of [C2H4O] n. its appearance is a white flake, flocculent or powdery solid and tasteless. Soluble in water (above 95 oC), slightly soluble in dimethyl sulfoxide, insoluble in gasoline, kerosene, vegetable oil, benzene, toluene, dichloroethane, carbon tetrachloride, acetone, ethyl acetate, methanol, ethylene glycol, etc.PVA / Polyvinyl Alcohol Powder is a water-soluble polymer, Non-toxic,insipid and non polluting; Good chemical Stability. Good adhesion;Film-forming ability; Insulation;Oil Resistance; Abrasion resistance; Gas Barrier Properties.It is fit to be architecture mortar additives.Polyvinyl alcohol(PVA) is an excellent water-based adhesive. The general product is flake, granular or flocculent. It is not easily soluble in cold water. Heating is generally required during dissolution. After being finely pulverized and surface treated, it has better cold water dissolving performance. But because of its thermoplasticity, pulverization becomes particularly difficult. Our factory adopts a special liquid nitrogen low temperature cooling process to ensure that the powder of the crushed material is uniform. So that the material has excellent water solubility.Paper making and paper processing industry The adhesion of polyvinyl alcohol to cellulose is better than that of casein, and the film forming property is stronger and the film strength is better. So polyethylene Alcohol as a paper processing volume is relatively large. 1. Paper adhesive PVA is a high efficiency paper adhesive, small amount, strong adhesion, complete alcoholysis PVA has water resistance, adjustable Use a transparent water resistant slurry. PVA made into slurry, stable quality, no moldy corruption, oil resistance after drying, Organic solvent resistance, suitable for paper adhesive. In order to reduce the cost can be mixed with clay, talc (to neutral or acidic The proportion of product should not be too large, so as not to stratification too fast), mixing white soil can also increase the initial adhesion, reduce the paper layer Penetration. a, paper tube, paper tube, paper box, kraft paper, corrugated paper, cardboard layer adhesives. Applicable to PVA 17-99 20-99 24-99 26-99 General paper tube, paper tube, paper box, kraft paper, corrugated paper, cardboard lamination and other requirements for stiffness and compressive strength, PVA with white soil suitable for use, PVA can make corrugated paper with water resistance. At the same time, in order to increase the adaptability of the operation, It can also be used with PVAC emulsion, starch, etc. b, book binding, envelope, padding adhesive, applicable to PVA20-99 24-99 17-88 24-88, etc.Product nameHydrolysisViscosityVolatilesAshPHPVA 05-8887-894.5-5.55.00.55-7PVA 10-8887-897.0-9.05.00.55-7PVA 12-8887-8910-125.00.55-7PVA 15-8887-8915-195.00.55-7PVA15-9291-9316-205.00.55-7PVA15-9594-9617-215.00.55-7PVA17-8887-8920.5-24.55.00.55-7PVA17-9291-9321-275.00.55-7PVA17-9594-9622-285.00.55-7PVA20-8887-8927-335.00.55-7PVA20-9291-9328-345.00.55-7PVA20-9594-9630-365.00.55-7PVA22-8887-8930-365.00.55-7PVA22-9291-9334-405.00.55-7PVA22-9594-9638-445.00.55-7PVA24-8887-8940-485.00.55-7PVA24-9291-9342-505.00.55-7PVA24-9594-9644-525.00.55-7PVA26-8887-8944-545.00.55-7PVA26-9291-9347-575.00.55-7PVa26-9594-9652-625.00.55-7Product Characteristic:(1) Solubility: hydrophilic, easily soluble in water (generally dissolved in hot water above 90oC), insoluble in almost all organic solvents.(2) Film formation: easy to form film, the mechanical properties of the film is excellent. In addition to H2O, PVA film has excellent resistance to H2, N2, O2 and other gases.(3) Adhesion: good adhesion with hydrophilic cellulose, paper, etc.(4) Thermal stability: when the 17-99 flake is heated to more than 130oC, the appearance gradually changes. Fully hydrolysed PVA begins to melt at about 230 ° C and decompose above 200 ° C.(5) Solvent resistance: PVA has strong resistance to weak acid and weak alkali, and has good oil resistance.(6) Reactivity: with excellent cross-linking reactivity, can cross-link with boric acid, acetaLl reaction with formaldehyde, acCetaldehyde, etc., the product has water resistance.Application field1, Polyvinyl alcohol can be applied in a variety of wall putty, drymix mortar, gypsum products, tile adhesive. It can effectively increase the adhesion of cement, ash calcium powder and gypsum. It can increase fluidity and slow the surface drying time to prevent product surface from cracking. It is suitable for wall/ceiling finishes and tile pastes.2, adding 1-2KG of Polyvinyl alcohol with fineness above 300 meshes, into the latex paint production process, can effectively improve the smoothness of the product, improve the film formation and reduce the amount of emulsion used 5-10KG.3, in the thermal insulation mortar system, 1 KG of Polyvinyl alcohol (160 mesh) has the similar effect of 4-5KG latex powder. In practical application, combine latex powder and Polyvinyl alcohol to use will achieve a better effect.1.
