UHMW-PE Tailings pipe--- Plastic insurance film of PE

 
On August 9, 2013, the central radio news broadcast a message like this: wal-mart and other two large supermarket when steamed steamed stuffed bun, use PE plastic film instead of traditional, at the bottom of cloth materials, cooking at high temperatures.This poses a threat to people's health.PE is short for polyethylene plastic, which can withstand temperatures up to 110 degrees, no toxicity, and in the long run in the 100 - degree environment will produce decomposition, contact with the food produce cross, eating more of this kind of food is necessary for human body has a certain influence.
Therefore, experts advise, do not use plastic products of hot food, in the pot cooking is more conducive to human health.
Hear the news about PE, don't naturally think of a different kind of chemical materials.Has studied chemistry at school knows that uhmw-pe, is a kind of high molecular material, its molecular weight can reach more than 2.5 million, is a kind of superior performance engineering plastics, is the upgrade version of PE.UHMW-PE after single pole screw extrusion, the formation of ultra-high molecular weight polyethylene pipe, widely used for tailings pipelines, pumping sand pipe, water pipe, etc.One of most used is tailing pipeline.
UHMW-PE Tailings pipe of the main performance is excellent wear resistance, its wear resistance is general steel pipe 4 to 7 times, 17.9 times that of phenolic resin, nylon 6 6 times, four times that of polyethylene, can greatly improve the service life of pipelines.
Tailing is the main reason of the pipe wear its unique molecular structure, its structure is linear structure, long molecular chain segments, not easy to be destroyed, so super durable, conveying a class of small particles of fly ash slurry effect is better, so it is mainly used for tailings pipelines, pumping sand sediment delivery pipeline, slurry pipeline, etc.In all kinds of wear resistance experiments, ultra-high molecular weight polyethylene pipe is behaved very well, wear and tear "minimum.
