Description

Technical Field

[0001] The utility model relates to the technical field of hot extrusion cooling, in particular to a cooling device for producing and preparing HDPE pipes. Background Art

[0002] HDPE pipe is a pipe made of high-density polyethylene (abbreviated as "HDPE"), which is a highly crystalline, non-polar thermoplastic resin. The appearance of the original HDPE is milky white, and it is translucent to a certain extent in thin sections. PE has excellent resistance to most domestic and industrial chemicals.

[0003] HDPE pipes are formed by hot extrusion using advanced production processes and technologies. They are corrosion-resistant, have smooth inner walls, low flow resistance, high strength, good toughness, and light weight. HDPE pipes are the second most consumed plastic pipe variety in the world after PVC-U drainage pipes.

When the pipe is cooled and taken out, the water on the surface of the pipe cannot be removed, which makes the pipe easily contaminated with dust, and the water easily drips on the ground and is difficult to clean, causing inconvenience in use.
