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
