Polyethylene Sheet Characteristics - Bochi

**Polyethylene Wear-Resistant Plate** is a composite wear-resistant layer plate formed by combining 40-60% carbide chromium alloy with a suitable steel substrate using an arc welding method. The material of the cladding layer is uniform, the appearance is regular, and the carbide in the microstructure of the wear-resistant layer is distributed in a fibrous manner, perpendicular to the surface. The surface hardness can reach above HRC67, and the high chromium carbide content of the hard alloy makes the wear-resistant composite plate suitable for extremely severe wear environments. It possesses the dual properties of high hardness materials and tough materials, making it irreplaceable with comprehensive excellent performance compared to other domestic engineering wear-resistant materials such as various alloy steel plates, cast wear-resistant plates, cast stone, rubber, polyurethane, etc. One remarkable performance of the **Polyethylene Wear-Resistant Plate** is its extremely high wear resistance, which is highly valuable in many engineering applications. Among all plastics, its wear resistance is the best, even surpassing that of many metal materials (such as carbon steel, stainless steel, bronze, etc.) in regular wear resistance. As the molecular weight of polyethylene increases, the material becomes more wear-resistant. So how to improve the wear resistance of high molecular weight polyethylene wear-resistant plates on its existing basis? By adding some wear-resistant technologies to the existing polyethylene wear-resistant plate, the wear performance of the lining plate can be greatly enhanced. Although the price is about 2 to 4 times higher than that of composite steel plates, its service life is several times that of composite steel plates, significantly reducing maintenance costs and downtime losses. In industries with large material handling volumes and severe equipment wear, such as mining, coal preparation plants, metallurgy, thermal power plants, and shipbuilding, the economic benefits of using wear-resistant high molecular polyethylene wear-resistant plates become increasingly evident. Common advantages of **Polyethylene Wear-Resistant Plates** include: 1. The wear resistance of this product ranks first among similar products. When the molecular weight does not exceed 2 million, the larger the molecular weight, the higher the material's wear resistance and impact resistance. 2. When the molecular weight of the polyethylene wear-resistant plate is below 500,000, the product's brittleness temperature will drop to -140°C. 3. If the polyethylene wear-resistant plate is under the action of liquid nitrogen, the usable temperature can reach below -269°C. 4. The water absorption rate is extremely low. Therefore, the physical and mechanical properties of the polyethylene wear-resistant plate are not affected by the humidity factors in the working conditions. 5. The impact strength of the polyethylene wear-resistant plate is high among existing plastics, maintaining a relatively high impact strength even at -70°C.
