There are also many types of products produced by this encapsulation material. When we produce products according to different structures and locations, we must improve the corresponding wear resistance or other properties according to the actual performance requirements, thereby increasing the overall performance advantage. Different products have different performance requirements for product materials in different workplaces. Polyurethane has higher mechanical strength, oxidation stability, flexibility, resilience, oil resistance, solvent resistance, water resistance and fire resistance. Such excellent performance characteristics, but when it is made into products such as rubber lagging, wheels or conveyor belts, because their work wear and consumption are more serious, they need good wear resistance. Then, the wear resistance factors that affect the polyurethane encapsulation are Which ones? 1. Material: The material of the rubber is an important factor to ensure whether the polyurethane encapsulation is abrasion resistant. Its performance parameters affect the quality of the encapsulation. Therefore, it is necessary to choose a rubber variety that meets the industrial and mining conditions. It has excellent wear resistance and can be compared Ordinary rubber is dozens of times higher and is an ideal high wear-resistant material. 2. Adhesion: In the process of using polyurethane encapsulation, it is often affected by long-term friction and centripetal force. If the selected adhesive cannot effectively bond, it will cause premature degumming and cause the system to stop. 3. Manufacturer: The selected manufacturer must have good on-site analysis and construction capabilities. According to the actual situation, choose rubber sheets of different thickness, hardness and wear resistance. Without a realistic choice, the encapsulation will wear out too quickly. Changing to a chain extender can enhance its wear resistance. MCDEA is a new type of aromatic diamine chain extender. Because there is no hydrogen atom on the ortho carbon atom of the amino group, and a gas atom is introduced in the meta position, and the stability is better, the prepared product has good wear resistance, heat resistance and mechanical properties. It not only improves the wear resistance of polyurethane encapsulation, but also reduces the toxicity.
