High molecular weight polyethylene sheet: high density polyethylene sheet will always be worn?
2020-04-30
The main material of high-density polyethylene board is high-density polyethylene, whose molecular weight is 3 million to 6 million, while the high-density polyethylene resin is only 300000 to 500000.
This difference is to ensure that the high-density polyethylene has sufficient strength, but we still have some problems in use, such as wear.
High density polyethylene board will always be worn?
Wear of high density polyethylene sheet is also a system engineering problem. There are many factors that affect the wear of high density polyethylene board, including working conditions, lubrication conditions, environmental factors, material factors, etc.
Changes in the physical and chemical properties of various factors may change the amount of wear and even change the wear mechanism. In the industrial field, the wear and adhesive wear of high-density polyethylene plates account for the proportion of workpiece wear failure.
Corrosion, corrosion, fatigue, fretting and other wear failure modes often appear in the operation of some important components, so people pay more and more attention to them.
