Trough Idler High Molecular Antiflaming and Electric Resistance

UltraHigh Molecular Weight Double Resistance IdlerThe ultra-high molecular weight double resistance idler is the company's new developed product. The idler body adopts the ultra-high molecular weight polyethylene pipe which is a new material have the following characteristics and advantages, such as: anti-static,flame-retardant, anti compression, wear-resisting,corrosion resistance, impact resistance, light weight, low friction coefficient, anti adhesion, self-lubricating, etc. It adopts special sealing technology which can play a good protection effect to the bearing. For the equipment which adopts this kind of idler, the service life is prolonged. Also, it can save energy, protect the belt, lower the labor intensity, avoid maintenance and improve the working environment.Character:
•High security: impact resistant, anti-static, flame retardant. In line with the national coal mine safety using conditions (MA).
•Abrasive resistance: the wear resistance is generally 3-6 times than the ordinary steel tube, and 10 times as much as other plastic tube.
•Anti-corrosion: high chemical stability,anti-corrosion tovarious kinds of corrosive medium and organic solvent.
•Low temperature resistance: reach high impact strength at minus 40ºCenvironment and maintain good performance under very low temperature.
•Impact resistance: highest impact resistance among all kinds of plastic testing by the national chemical building materials test center.Application fields:
•Coal mine industry: transportation for coal, gangue, stuffing, etc.
Electric power industrytransportation for coal and coal ash in power plant
•Steel industry: transportation for ore, fine ore, etc.
•Ocean engineering: transportation for material in wharf, port,etc.
•Food processing: transportation for food, raw material, food material, etc.
•Cement industry:transportation for stone, rock flour, raw material, etc.
•Chemical industry : transportation for corrosive materials
•Low scaling: good self-lubrication and adhesive resistance.
•Light weight: for the density, it is less than 1/7of the steel pipe;for the weight, it is only1/4of the steel pipe. It is easy in installation and replacement, with low labor intensity and installation costs.Performance comparisons with other materials:
