The extruding properties of several kinds of rubber

 

　　The extruding process is used to press out the cylinder wall and the screw part of the machine, so that the glue can be extruded and preliminarily designed, and the extrusion process also becomes the extrusion process.

　　The main equipment of extruding process is extruder.

　　The extruding properties of several kinds of rubber: the pressure of natural rubber is fast and the shrinkage of semi-finished product is small. Body temperature of 50-60 ℃, Rubber Parts starting from 70-80 ℃, mouth 80-90 ℃; Styrene-butadiene rubber pressure out of the slow, shrinkage deformation, surface roughness, the body temperature of 50-70 ℃, the nose temperature 70-80 ℃, the mouth temperature 100-105 ℃; Neoprene delivery without sufficient heat, body temperature 50 ℃, ℃ the nose, Custom Mold Rubber Parts mouth type 70 ℃; Ethylene propylene rubber extrusion speed, small shrinkage rate, body temperature of 60-70 ℃, the nose temperature 80-130 ℃, Rubber Seal mouth, 90-140 ℃. The butyronitrile rubber has poor performance and should be fully heated when pressed. Body temperature of 50-60 ℃, the nose temperature 70-80 ℃.
