Polyethylene plate,ultrahigh molecular weight - Introduction
Ultra-high molecular weight polyethylene (UHMWPE) sheet has the following properties:
1. High wear resistance: UHMWPE plate has excellent wear resistance and is one of the most wear-resistant materials in all engineering plastics.
2. Low friction coefficient: UHMWPE plate has a very low friction coefficient and good self-lubricating performance, which can reduce the energy loss during equipment operation and reduce the wear of mechanical parts.
3. High impact resistance: UHMWPE plate has excellent impact resistance, can maintain high toughness at low temperatures, and can effectively absorb impact energy and reduce the impact force of object collision.
4. Chemical resistance: UHMWPE plate has good corrosion resistance to acid, alkali, solvent and other chemicals, and can be used stably for a long time in harsh chemical environment.
The main uses of UHMWPE sheet include:
1. Rollers and skateboards: UHMWPE plates are widely used in conveying equipment, conveying lines and skateboards, which can reduce friction and reduce wear.
2. Protective material: due to the high wear resistance and impact resistance of UHMWPE plate, it can be used to make protective covers, baffles, guide rails and other parts of industrial equipment.
3. Medical Devices: UHMWPE plate is used to make artificial joints, implant devices and other medical devices, and has important applications in orthopedics and joint repair.
The common preparation methods of UHMWPE plate are hot pressing and injection molding:
1. Hot pressing method: UHMWPE particles are heated to the melting point, then pressed in a mold, and cooled to form the required plate.
2. Injection molding method: The hot-melt UHMWPE is injected into the mold, and formed into a plate through pressure and cooling.
in the use of UHMWPE plate need to pay attention to safety issues:
1. When operating, you need to wear the necessary protective equipment, such as glasses, gloves, etc., to avoid direct contact with the material.
2. In the process of processing and use, pay attention to ventilation to avoid the accumulation of harmful gases.
3. Avoid the UHMWPE plate contact with high temperature objects to avoid melting or deformation.
4. Adhere to the safety operation procedures, the correct use of UHMWPE plate, to ensure the safety of personnel and equipment.
