Foam liquid is easy to inject into large tanks with different characteristics, as well as foam solutions where chemical reactions have occurred. The viscosity increased rapidly and the injected foam did not react. Liquid injection foam can not push the injection of liquid to the front of the foaming process, and local cavitation occurs in the box
Before and after foaming, black and white materials should be treated with constant temperature to control the foaming temperature at Celsius. The temperature of the preheating furnace foaming equipment should be controlled in degrees Celsius, and the temperature of the foaming mold should be controlled in degrees Celsius
In between, the temperature of the foaming mold is too low, the foaming system has poor fluidity, long curing time, incomplete reaction and cavitation. When the temperature of the foaming mold is too high, the inner container of the plastic container is deformed by heat, and the foam system reacts violently. Therefore, the temperature of the foaming mold and the ambient temperature of the foaming furnace must be strictly controlled.
Especially in winter, in the morning, the foaming mold, preheating furnace, furnace body, door body must be foamed and preheated for more than a minute. After a period of summer foaming, the foaming system of the polyurethane foaming machine should be cooled and cooled.
