Cast basalt composite pipe enterprises explain various methods of producing cast basalt composite pipes

There are many manufacturing methods of cast basalt composite pipe, such as extrusion processing, ultra-high speed fusion processing and so on. Due to different production methods, the functions of cast basalt composite pipe are also different. Let's understand how many production methods of polyethylene are:

Extrusion processing method: firstly, the lubricant is mixed with other processing aids into the material. During production, the lubricant in the material seeps out. The self-lubricating extrusion of cast basalt composite pipe is to add an appropriate amount of external lubricant to reduce the friction and shear between polymer molecules and metal die wall, and improve the uniformity of material activity, demoulding consequences and extrusion quality.

Ultra high speed fusion processing method: the blade mixer is adopted, and the rotating speed of the blade can reach 150m / s, so that the material can rise to the processing temperature in only a few seconds. The homogeneous composite material with high modulus can be obtained by nominal polymerization of polyethylene with alumina dried in heptane in the presence of catalyst.

Carbon black or metal powder can improve the antistatic property of polyethylene and improve the conductivity. Glass beads, glass fiber, mica and talc powder can improve the hardness, stiffness and temperature resistance of polyethylene.
