Dextrin also can ferment in summer, should add antiseptic(brown aluminum oxide). The adhesive property of pulp residue is not as good as that of syrup. It can obtain better coating strength when it is shared with clay. The pulp residue is acidic. Therefore, when using alkaline bentonite as suspending agent, the dosage of pulp residue should be controlled, which should not exceed 1%(aluminum oxide grit). The drying and hardening process of pulp residue is reversible.

The moisture can be absorbed again after coating drying to reduce the strength(silicon carbide abrasive). Therefore, the coating should be poured early after drying. The grade of polyvinyl alcohol is different, and its properties are also different. The thickening effect of polyvinyl alcohol is remarkable, with high strength and low gas generation(100 grit aluminum oxide media). When casting, the bright carbon can be formed on the surface of the coating, which helps to form the easy to peel sintering layer.

(brown aluminum oxide 22 grit wholesale suppliers uk)Poly (ethylene glycol) (PVA) is an organic polymer, a water-soluble resin, tasteless, non-toxic, white or light yellow powder(brown aluminium oxide). Polyvinyl alcohol is obtained by the change of vinyl polyester acid; it is usually obtained by alcoholysis of polyvinyl acetate and alkali. The raw materials are petroleum and natural gas(aluminum oxide abrasive). The grade of polyvinyl alcohol used as casting binder is PVA17-88 (degree of polymerization 1700, degree of alcoholysis 88%).

In the coating and sodium base moistening soil to share(pink corundum), can obtain good suspension, quick drying and good brushing property, commonly used polyvinyl alcohol to prepare water-based self-drying coating, polyvinyl alcohol is not easy to dissolve in cold water, when used in boiling water for a period of time to dissolve, so the use of partial alcoholysis of vinyl alcohol, water solubility is good, high strength(emery abrasive). Generally, it has uniform appearance and blue light.(brown aluminum oxide 22 grit wholesale suppliers uk)

Polyvinyl acetate emulsion does not react with other components such as suspending agent and binding agent in the coating(black corundum), and does not make the bentonite -CMC solution thickened. Styrene acrylic emulsion is a kind of emulsion polymerized by styrene and butyl acrylate. Polyvinyl acetate emulsion is a water-soluble organic solvent with no pungent odor(black silicon carbide). It can be dried at room temperature with good film forming property.

(brown aluminum oxide 22 grit wholesale suppliers uk)It is easy to form film above 5 ℃ and demulsify when meeting strong acid and organic solution(brown fused alumina). It can be used for water-based coating of EPC. VAE emulsion (vinyl acetate ethylene copolymer emulsion) is formed by copolymerization of vinyl acetate and ethylene under applied pressure. In VAE emulsion, the content of ethylene is 5%~30%(synthetic corundum). The emulsion is characterized by high bond strength, good water resistance, good alkali resistance and low film forming temperature.

Rosin is a kind of thermoplastic natural resin extracted from pine resin(white alumina). Its appearance is yellowish translucent or light brown block, which is brittle and easy to crush. The main components of rosin are rosin acid and rosin anhydride. The melting point of rosin is 75 ~ 135 ℃(green silicon carbide). It melts when heated and returns to solid state after cooling. Rosin is insoluble in water, moderately soluble in ethanol, completely dissolved in acetone and other organic solvents.(brown aluminum oxide 22 grit wholesale suppliers uk)
