The Weifang Tainuo chemical industry Limited company is located in “the world kite” - - Weifang, south near the rubber Jinan railroad, north depends on 309 federal highways, the blue silver highway, the geographical position is superior, the traffic conditions are convenient. in 2006 sets up with joint forces by the original Shandong four stars in the bowl of the big dipper specialized team, is domestic devotes to the development green environmental protection safety product for the mission specialty company.
Tainuo Chemical always focus on chemicals and keep researching and supplying chemicals for our customers .Now we will supply you with new series chemical: Oxalic Acid
Since the partially alcoholized PVA contains more acetate groups, and the volume of the acetate group is much larger than the hydroxyl group, there is a large steric hindrance, so that the partially alcoholized PVA cannot form a compact crystal structure. It can only form loose structures with large
The degree of alcoholysis has an effect on the water solubility, viscosity, adhesion and serosity of the slurry.1. Water solubility:PVA with fully alcoholysis is poor in water solubility,for example,PVA with Alcoholysis degree more than 99%(Mole fraction) begin to dissolve when it is heated above 9
Melamine formaldehyde molding compound is made of "melamine formaldehyde resin" as a base material, "Alpha" cellulose as a filler, and added with pigments and other additives. It has the characteristics of water resistance, high temperature resistance, non-toxicity, bright color and convenient moldi
Melamine is an industrial chemical; a white crystalline powder consisting of nitrogen, carbon and hydrogen.
Most melamine is used as a starting product for the manufacture of adhesives and resins that are used in woodbased panels, laminate floors and decorative surfaces for furniture. It is also present in thermoset plastics, flame retardants and many other products.

Melting point: It be melt under 354℃ under ordinary pressure.
Sublimation temperature: 300℃
Dissolvability: It can dissolve in carbinol, formaldehyde, acetic acid, hot glycol, glycerin, pyridine; it lightly dissolve in water, ethanol; it cannot dissolve aether, benzene, and carbon tetrachloride. Its water solution presents alkalescence.
Chemical Capability: Melamine presents alkalescence, can react with various acidums to generate melamine salt. In strong acid or strong alkali liquor, melamine will hydrolyze---amidocyanogen will be slowly replaced by hydroxyl, thus generate cyanuric acid diacid amide, cyanuric acid monamide, and cyanuric acid. Among them, the reaction of melamine and formalin is the most important part.
