Importance Of Wear Resistance Of Chain Guide Parts

In our daily life and work we can often see chain guide parts, its appearance brings us great convenience, chain guide parts in the long-term use process, there will be different degrees of friction between the two contact surfaces, will cause different degrees of scraping and straining on the surface of the guide rail, seriously affecting the processing accuracy and productivity of the equipment. Traditional repair methods usually use metal plate inlay or replacement, but requires a lot of accurate manufacturing and manual scraping. Repairs require many processes and take a long time. Currently, polymer composites can be used to solve the problem of machine tool guide scrapes and strains.

　Chain guide and its wear resistance is also very strong, so in some as long as you can use this product, basically use the chain guide. The main reason is the following characteristics

　　Higher wear resistance, 4 times higher than nylon 66 and PTFE, 6.9 times higher than carbon steel. Chain guide is very good corrosion resistance, in addition to some strong acids at high temperatures will have corrosion, in other alkalis, acids are not subject to corrosion. The stability is also very good, it will not cause the chain guide to change its nature because of some elements.

　　Chain guide has high impact resistance, the impact toughness value of this product is higher in the existing engineering plastics, this product is according to the standard, cantilever beam impact test to achieve no breakage; polyethylene chain guide has better resistance to environmental stress cracking, the modulus of elasticity is more than 1.5 times of PE100.

　　We should also learn is that polyethylene sheet is a kind of polymer, the base material is PE material, through the mixing, calendering, sintering, cooling, high-pressure shaping, demoulding, shaping and other processes to produce, has its own particularity of its mechanical mechanical properties by the temperature, the relative molecular mass of the impact is very large. One of the properties that enhances the attractiveness of PE sheet is the high wear resistance of PE sheet, a property that is invaluable in a very wide range of engineering applications. It also has one of the better abrasion resistance of all plastics, even the regular abrasion resistance of very many metallic materials is not as good as it is.
