Polyurethane Roller mill machine manufacturing methods

A polyurethane rubber roller mill machine manufacturing method is to use polyester and diisocyanate reaction made with-NCO group of prepolymer, and then-NCO content by adding the calculation of the amount of agent MOCA participate in the growth of chain reaction, reactant After pouring, curing and aging process and made of rubber roller mill Valley. Cots this surface, good flexibility, testifies to the Valley when the mechanical properties of stability, low temperature rise, off-rate of more than 90.5 percent, processed products in line with national standards, the life of an ordinary cot Cots 4.5 ~ 5 times more than existing technology and the production of durable polyurethane rubber roller also.
