Why wear-resistant material conveying hoses use PU material wear-resistant hoses in the majority
The abrasion performance of industrial hoses is an important factor affecting safe production. With the continuous development of science and technology, the materials are also constantly innovated, such as PVC, PU and other materials. Among them, the application of PU hoses has spread to various industries such as electronics, printing, food, pharmaceuticals, chemicals, building materials, machinery, etc., and is developing at a high speed. One of the main reasons for its wide application is its excellent wear resistance.
We know that when transporting abrasive materials (such as ash, coal powder, particles, mineral concentrate, etc.) in the pipeline, there is a problem of rapid hose wear, especially when the bending part wears faster, it will Seriously affect the service life of the hose. If the wear-resistant material conveying hose made of PU (polyurethane) is used, its wear resistance is 2.5 to 5 times better than that of rubber, and 3 to 4 times better than that of soft PVC. It is especially like Hangzhou Haikuo's wear-resistant hose, except for its abrasion resistance. It has strong performance, high tensile strength, high elasticity, low compression deformation, and high tear propagation resistance. It guarantees a long suction operation life to a large extent and saves business costs.
PU polyurethane wear-resistant hoses can generally be divided into air, ventilation, suction and transportation, dust collection, anti-static suction hoses, etc. according to the different working conditions. And it has a very wide range of applications, not only in industry but also in agriculture, and the fields involved also cover petroleum, steam, fire protection and other aspects. One of the most commonly used industrial hoses is the wear-resistant PU steel wire tube.
Abrasion-resistant PU steel wire hose is a multi-purpose hose, with various equipment for suction and transportation, suitable for the transmission and suction of abrasive materials. In the plastics industry, it can be used for high-speed transmission of plastic particles and scraps. In the woodworking industry, textile industry, dust removal field and industrial cleaning field, it is often used for solid particles and gas transportation, suction paper scraps, textile fibers, transportation of dust and powder, and also used to protect hoses, for resistance to wear and transportation. Abrasive solids, also often used as sand suction hoses, stone transportation hoses, garbage collection trucks, sanitation truck hoses, sweeper hoses, leaf suction hoses, grain transportation, vacuum and negative pressure resistance Suck.
