Reaction of acrylate formic acid
The reaction of acrylate phenol is similar to that of alcohol, but the relative density of electron cloud of oxygen molecule in methyl group of phenol is reduced due to the electric absorption effect of benzene ring, the reaction specificity between acrylate acrylate is reduced due to the price of polyurethane. The key of such reaction is the closed reaction of acrylate
Reaction of acrylate water
The reaction is the key reflection of polyurethane foam. The price of polyether polyols is converted into carbon dioxide in the reaction, which makes water become organic chemical foam adhesive for foaming polyurethane. However, it shows that excessive heat excessive heat will lead to the burning of core of foam plastics. In addition, excessive water consumption can make the conversion of urea into high polymer, which may cause the soft feeling of PU soft plastic foam to drop. Therefore, PU soft plastic foam is produced. When plastic body is used, the sound of strictly controlling water is less than 4%.
Other products of polyesters such as vulcanized rubber, building coatings, chemical fibers so on, which are expected to appear foam plastic cavitation, are very strict in water. They do expect the reaction due to the contact of raw materials, organic solvents moisture in cold cold air with acrylic ester.
