Linear guide rail processing - polymer chain guide rail - customized non-standard guide rail special

Ultra high molecular polyethylene wear-resistant strip, also known as chain guide rail, plastic guide rail, lining strip, cushion strip and friction strip, greatly reduces the hard friction between the conveyor belt and the frame and effectively prolongs the service life of the conveyor belt
There are many kinds of liners, including direct embedded and many flat types with different width and thickness
It is widely used in chain conveying equipment to support and guide the chain, so as to prevent the chain from falling off and clamping teeth during long-distance conveying

It is mainly used in conveying machinery, food processing, packaging machinery, automatic assembly line, machine tool guide rail, guide strip, lining strip, insert strip, etc
It has many excellent properties such as wear resistance, self lubrication, low temperature resistance, impact resistance, non adhesion, corrosion resistance, low water absorption and sanitation

  The chain guide rail has self lubrication, high wear resistance, low sliding friction coefficient, strong impact resistance and compressive stability, is suitable for food hygiene requirements, low noise, insulation and thermal stability
It is a trusted partner for all product material packaging, canning and conveying machines, die-cutting machines, glue nail coupling lines, riding nails, glue bag machines and printing machines

  Superior performance of ultra high molecular weight polyethylene (UHMW-PE) chain guide rail:
  Wear resistance
The abrasion resistance of UHMWPE ranks first among plastics and exceeds that of some metals
Compared with other engineering plastics, the mortar abrasion index of UHMWPE is only 1 / 5 of PA66 and 1 / 10 of hepe and PVC; Compared with metal, it is 1 / 7 of carbon steel and 1 / 27 of brass
Such high abrasion resistance makes it difficult to use the general plastic abrasion test method
To test its wear resistance, a mortar wear test device is specially designed
The wear resistance of UHMWPE is directly proportional to the molecular weight
The higher the molecular weight, the better the wear resistance

  Impact resistance
The impact strength of UHMWPE is about twice that of impact resistant PC, 5 times that of ABS and more than 10 times that of POM and pbtp
The impact resistance is so high that it is difficult to break it by using the usual impact test method
The impact strength increases with the increase of molecular weight
It reaches the maximum when the molecular weight is 1
5 million, and then decreases gradually with the continuous increase of molecular weight
It is worth noting that it can also maintain excellent impact strength in liquid nitrogen (- 195 ℃), which is not available in other plastics
In addition, it has higher surface hardness under repeated impact

  Self lubricity
UHMWPE has very low friction coefficient (0
05 ~ 0
11), so it has excellent self-lubricating performance
The dynamic friction coefficient of UHMWPE is 1 / 2 of that of PA66 and POM under water lubrication and second only to polytetrafluoroethylene (PTFE) under non lubrication
When it works in sliding or rotating form, it is wetter than that of steel and yellow copper after adding lubricating oil
Even better smoothness
Therefore, in the field of tribology, UHMWPE is known as a friction material with very ideal cost / performance
