Technical requirements for protective film coaters (1).

The viscosity and other rheological characteristics of the adhesive of the protective film coater are important properties that affect the behavior of the protective film coater, according to the dependence of viscosity with shear speed, the fluid can be distinguished into Newtonian fluid, expansion body and pseudoplastic. According to the change of viscosity shear time, the fluid is divided into Newtonian fluid, contact variant and flow variant. The greater the rheological properties of the adhesive deviate from the Newtonian fluid.
