General problems of hydraulic hose
Ultra high molecular weight polyethylene (UHMW-PE) is a thermoplastic plastic. It combines the superior properties of most plastics. Thus it can resist impact, low temp, wear and chemical corrosion. Besides, it can lubricant itself and absorb impact energy. These are currently the highest among plastics. In recent years, this new type plastic is popular in Europe and America. While the demand continues growing. At the same time, UHMWPE products are more and more used in our country. It is a promotion project in the future of our industry.
The typical products of such material are chemical hose and food grade hose. With such material, these industrial hoses can have much better property.
UHMWPE adopts Ziegler type high efficiency catalyst low pressure synthesis method. While the molecular weight is to be above 5 million. But there will be the thermal degradation during process. Thus the products with greater than 1.7 million can has good performance.
Great properties of UHMWPE
High wear resistant
Among all current plastics, UHMWPE has the best wear resistance. The higher the molecular weight, the better the wear resistance is. Besides, it is far more than many metal materials such as carbon steel, stainless steel, bronze, etc. For example, UHMWPE hoses have a service life 4-6 times that of steel pipes in strong corrosion and high wear condition. While the work efficiency increases by 20%. Thus such material is a good choice for energy saving.
Corrosion resistant
UHMWPE hose will not corrode in alkali solution. Besides, it can work as normal in acid at 80℃. What’s more, it has stable performance in 75% sulfuric acid and 20% nitric acid. In addition, it is also stable to sea water and liquid detergents.
