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

DMAC is used as a solvent of synthetic fiber (acrylonitrile), polyurethane spinning and polyamide resin synthesis and used as an extraction and distillation solvent for separating styrene from C8 fraction and widely used for polymer membranes, coatings, pharmaceuticals, and used to synthesize antibiotics, pesticides and insecticides. It can be used as a reaction catalyst, electrolytic solvent, paint remover, and adduct and complex of multiple crystalline solvents.
It is a colorless and transparent liquid that is combustible and miscible with water, methanol, ether, ester, benzene, chloroform and aromatic compounds at any ratio. Its freezing point is -20℃, boiling point is 166℃, 96℃(10.7kPa), 85-87℃(4.4kPa), 74-74.5℃ (3.47kPa), 66-67℃ (2.0kPa) and 62-63℃ (1.6kPa), relative density is 0.9366 (25/4℃) and 0.9599 (0/4℃), refractive index is 1.4380, and flash point (open cup) is 70℃.
•Production mode: Synthetic process of acetic acid and DMA is adopted. It adopts advanced rectification technology for catalytic reaction to strengthen reaction and reduce energy consumption. Separation effects and product yields are increased significantly and the process is simplified.
