Do high temperature melt dosing pumps shear the material when conveying polymer?

There will be shear, for different materials with different shear strength, such as rubber, its shear heat will be more powerful, for general polymers, there will be a temperature rise, and will be shear thinning. General polymer, especially the higher requirements of the occasion, do not want to have a high shear temperature rise, such as in polyester, the requirements of the shear temperature rise of no more than 3 ℃, for these conditions, we need to do some special design to prevent the material temperature rise is too large (such as for the transmission of rubber, Zhengzhou Batte has a special transmission of rubber R series of melt pumps). High-temperature melt metering pump conveying materials in the process, shear is bound to exist, but controllable.

Zhengzhou Batte melt metering pump manufacturers to provide melt metering pumps can meet the low viscosity chemical materials to high-viscosity rubber and other materials, conveying, pressurization, metering, viscosity range from 0.0001 ~ 40,000 Pa.s; Zhengzhou Bart according to customer demand, to provide the whole process, the whole production line with melt metering pump solutions.
