Molding Temperature Of PVC Hose

1 raw materials are measured according to the formula requirements. PVC resins and plasticizers are mixed into the high-speed mixer before mixing. The specific requirement is the same as the raw material mixing method of PVC hose. When the temperature is up to 110~120 degrees. In the cold mixer, mix and break the caking material, so that the mixture temperature is reduced below 45 degrees Celsius.

2 for the inner layer of the extruded PVC hose, the temperature of the extruder barrel feeding section is 90~120 C, the plasticizing section temperature is 130~150 C, the homogenized section temperature is 160~170 C, and the molding mold temperature is 170~180 C.

3 for the outer layer of extruded PVC hose, the temperature of the extruder barrel feeding section is 110~130 C, the plasticizing section temperature is 140~160 C, the homogenized section temperature is 160~170 C, and the molding mold temperature is 170~180 C.
