%26nbsp2. High melting point, low viscosity, high adhesion to metal, easy to hydrolyze;
%26nbsp3. Hydrophilic, the binder is sensitive to water at high temperature, drying temperature 150 ° C -160 ° C, time 4 hours or more.
Preferences:
%26nbsp1.L/D generally takes 20-22, three-segment distribution L1=50-60%, L2=20-30%;
%26nbsp2.Using low shear, low compression ratio screw compression ratio ε=1.8-2.2, discoloration or opacity due to shear overheating h3=0.09-0.10D;
%26nbsp3. When using recycled material (sheet), increase the conveying capacity of the feeding section and adopt the forced feeding plasticizing system.
