A high-performance, abrasion-resistant, scaling-resistant material

摘要

Contrast tests of abrasion by ejection of pulverized coal between a novel visco-elastic material " ultra-high molecular weight polyethylene" and other materials as well as industrial test of ash piping in the site of a thermal power plant were carried out. The results showed that the performance of the former against abrasion and impact is excellent, the mechanism of its abrasion resistance is unique, it possesses good property of scaling resistance and has thus a valuable perspective in development and application as an anti-abrasion and anti-scaling material. A composite pipe lined with such a material has obtained a Chinese Patent, and a small scale pilot production is now under way.
