Problems solved by technology

[0002] In the production process of conventional HDPE water supply pipes, HDPE resin and black masterbatch are generally used for extrusion production, but due to the non-polarity and hydrophilicity of the surface of carbon black, it is easy to agglomerate and absorb moisture during processing and storage, resulting in HDPE It is difficult to disperse uniformly in the polymer, which obviously affects the strength, oxidation induction time and hydrostatic strength of the pipe.
