What is the function of the barrel? What are the characteristics of the structure?

The barrel includes a screw, which rotates in the barrel. When the screw rotates and the thread is pushed, the heat is transmitted to the material by heating outside the barrel. In addition, the volume of the thread is gradually reduced, so that the material is evenly mixed and plasticized into a mo......

Why should add ACR or CEP, MBS and other materials in the formula when extruder processing UPVC pipes, and what are their characteristics

Due to the high brittleness, low melt strength and poor processing fluidity of UPVC materials, modifiers usually need to be added in the processing to improve the fluidity of UPVC, melt strength and material toughness. ACR or chlorinated polyethylene (CPE) and MBS are the modifiers of UPVC.

Brief Introduction to the Principle of Twin Screw Extruder

On the whole, the study of twin-screw extrusion theory is still in the initial stage. This is the so-called "skills more than science". From the study of its extrusion process, there are roughly three links:

Maintenance and repair of extruder reducer

The reducer is an important part of the pipe extrusion equipment. The following are the precautions for the maintenance and repair of the reducer:

Five Points for Attention in PVC Pipe Production

In the production process, since PVC is a kind of heat sensitive material, even if heat stabilizer is added, it can only increase the decomposition temperature and prolong the stable time without decomposition, which requires strict control of PVC molding temperature. Especially for RPVC, since its......
