There are two heating methods for PVC mixer, one is self friction heating, and the other is assisted heating and insulation by heating sheet.

The heating strip is used for auxiliary heating or insulation. The power and quantity of the heating strip can be determined according to the mixed materials. Why is the heating strip easy to break? It mainly includes the following points:

1. The installation position of the heating plate is incorrect. When installing the heater, it should be close to the outside of the barrel (fixed by screws) to allow the heat to quickly transmit to the outer surface of the sandwich barrel, and then to the inside of the barrel through the heat transfer oil. If the installation gap is large (the fixing screws are not tightened), it will cause hollowness, and the local temperature is too high, which will cause the heating plate to burn out.

2. No. 320 heat transfer oil is not added to the barrel interlayer, so the heat cannot be uniformly transmitted. The local temperature is too high, and more heat cannot be obtained inside the barrel. The detection temperature is low, and the heating plate is always in working condition, which is easy to cause damage.

3. The power and voltage of the heater do not conform to the voltage in the electrical operation cabinet. Generally, 220V or 24V heater is used in China.
