Principles to be followed by twin screw extruders
The principles that should be followed in the use of twin-screw extruders include the principles of temperature and deceleration, as well as the principles of structure. When the twin-screw extruder is working, it has to overcome a lot of resistance, so it is wound on an inclined plane in the structure. On the center layer, this increases the pressure to reduce drag.
The principle of slowing down. In the working process of the twin-screw extruder, the change of its speed is realized by adjusting the speed of the motor. Usually, the full-speed rotation of the motor is very fast for the twin-screw extruder, which will cause a lot of Therefore, in the third stage of this process, it is necessary to decelerate, and it is necessary to ensure that the deceleration rate must be matched with the work without error. , which will cause a lot of energy to be consumed, which requires adding a pulley block in a deceleration stage.
temperature principle. The twin-screw extruder can extrude thermoplastics, which will melt during the heating process and solidify again during cooling, so it is necessary to use heat during the extrusion process to ensure that the plastic reaches melting temperature, so where does this heat need to come from? Among them, the cylinder heater and the feed preheating play a very important role when it is turned on. In addition, the energy input by the motor is also a very important heat source. In the actual operation process, the temperature of the rear cylinder is very important, which affects the conveying speed of the solids in the feed. Generally speaking, the temperature of the mold and die head should be able to reach the melting temperature or relatively close to this temperature.
