What are the factors that affect the efficiency of the bioplastic extruders?

The bioplastic extruder is working under high temperature, high pressure, high mechanical torque, and high friction conditions for a long time. What factors will affect the efficiency of the bioplastic extruder? How should we maintain the bioplastic extruder on a daily basis?

Here is a list of the following

What are the factors that affect the efficiency of the bioplastic extruders?

A bioplastic twin-screw extruder is composed of several parts, such as a transmission device, feeding device, barrel, screw, etc. The role of each part is similar to that of the single-screw extruder. The difference with the single-screw extruder is that the twin-screw extruder has two parallel screws placed in the same barrel, and there are many different forms of twin-screw plastic extruders, the key difference is the screw structure. The screw structure of a bioplastic twin-screw extruder is much more complex than that of a single-screw extruder because the screw of a bioplastic twin-screw extruder has issues such as the direction of rotation and degree of engagement. bioplastic extruders must pay attention when used, only the correct actual operation of the twin-screw plastic extruder can reduce the wear and tear of bioplastic extruder, and can extend the service life of bioplastic extruder. The factors that affect the efficiency of the bioplastic extruder are roughly the following

Plastic extruder material and manufacturing quality.

The filling material in the formula and also the lubricant quality has a greater impact on the wear of the plastic extruder.

In addition to the machine and equipment material, heat treatment process, production processing, assembly accuracy, production of raw material hardness, particle size, filler addition, and processing process on the bioplastic extruder abnormal wear and tear is also a big impact.

How to carry out daily maintenance of bioplastic twin-screw extruder?

After 500 hours of use, there will be iron chips or other impurities in the gearbox from gear grinding down, so the gears should be cleaned and the gearbox lubricant should be replaced at the same time.

After a period of time, the extruder should be thoroughly inspected to check the tightness of all screws.

lf the power is suddenly cut off during production and the main drive and heating stop, when the power is restored, each section of the barrel must be reheated to the specified temperature and kept warm for a period of time before the extruder can be started.

If you find that the meter and pointer's steering is full, you should check whether the contact of the thermocouple and other sidelines is good.
