Carrying capacity of hdpe plastic sheets uhmw plastic sheet blocks
Ultra-high molecular weight polyethylene sheet is a new type of polymer material with moderate value and excellent performance. It is a well-known thermoplastic engineering plastic (structure: synthetic resin, plasticizer, stabilizer, colorant), hdpe plastic sheet the board almost concentrates the outstanding advantages of various plastics, and has unmatched wear resistance, impact resistance, corrosion resistance, impact energy absorption, hygiene, and low temperature resistance of ordinary polyethylene liners and other engineering plastics. , Comprehensive properties such as not easy to absorb water and low density.
The current processing of UHMWPE plastic sheet block mostly uses the sintering molding method. The melting temperature is 220~260C. For materials with larger molecules, the recommended melting temperature range is 200~250C. Selecting preferred raw materials with a molecular weight of more than 3 million and scientifically formulating them can obtain the preferred product with a reasonable process.
For UHMWPE sheets, its load-bearing capacity is not like that of metal materials, which mainly depends on the strength and stiffness of the material. In addition, because the mechanical properties of high molecular weight polyethylene are greatly affected by temperature, its load-bearing capacity It also has a great relationship with the material’s use environment temperature, the size of the friction coefficient of the material, the hysteresis energy consumption and the modification of the material. Therefore, the strength and strength design of HDPE plastic sheet is much stronger than that of metal. These are the main determinants of the load-bearing capacity of UHMWPE plastic block sheets. We must use it reasonably to fully demonstrate its performance and obtain better benefits.
