Polyurethane scraper consists of a plurality of narrow polyurethane scraper, with a hollow buffer hole, for a variety of belts have a good follow.
Polyurethane scraper has the following characteristics:
1, a wide range of hardness. Still have rubber elongation and resilience at high hardness.
2, with good low temperature performance.
3, oil. Polyurethane blade is a highly polar polymer compound, and non-polar mineral oil affinity is small, almost no erosion of fuel oil and mechanical oil.
4, vibration absorption performance, can do damping, buffering effect. In the mold manufacturing industry, alternative rubber and spring.
5, radiation resistance. Polyurethane high energy ray performance is good, in the 10-10 Ge radiation dose still has satisfactory performance.
6, high strength. Their tear strength and load carrying capacity are much higher than those of general purpose rubber under rubber hardness, and their impact strength and bending strength are much higher than plastic at high hardness.
Polyurethane blade with high wear resistance, high resistance to aging, high solvent resistance, and long service life. Used for scraping and adhering ash powder and powder materials on the conveyor belt of coal chemical industry, such as coal transportation, fertilizer transportation and gravel transportation. It is characterized by super-wear-resistant polyurethane composite material, which is 2 times the service life of ordinary polyurethane. It is widely used in electric power, mining, coal, transportation machinery and other industries.
