Application of polyurethane rubber wheels in production enterprises
1. The physical and mechanical performance indicators can be adjusted through the selection of raw materials and the adjustment of the formula, and the polyurethane coated wheels can be flexibly changed within a certain range to meet the unique requirements of users for product performance. For example, hardness is often an important indicator of users’ products. Polyurethane elastomers can be made into soft printing rubber rollers with a Shore A hardness of about 20, or hard rolled steel rollers with a Shore D hardness of 70 or more. This is difficult for general elastomer materials and can be adapted to the needs of different users. Polyurethane elastomer is a polar polymer material composed of many flexible and rigid segments. As the proportion of rigid segments increases and the density of polar groups increases, the original strength and hardness of the elastomer will increase accordingly.
2. Superior wear resistance.
In the presence of water, oil and other wetting media, the wear resistance of polyurethane coated wheels is often several to several tens of times that of ordinary rubber materials. Although metal materials such as steel are very hard, they are not necessarily wear-resistant; others such as rice hulling machine rubber rollers, coal preparation vibrating screens, sports ground race tracks, and dynamic oil seals for crane forklifts Rings, elevator wheels, roller skate wheels, etc. are also where polyurethane elastomers come in.
3. Diverse processing methods and wide applicability.
Polyurethane rubber-coated wheel elastomer can be molded by plasticizing, mixing, and vulcanizing processes like general rubber; it can also be made into liquid rubber, poured into compression molding, spraying, potting, and centrifugal molding (referring to CPU); Granules, like ordinary plastics, are formed by injection, extrusion, calendering, blow molding and other processes (referring to CPU). Molded or injection molded parts can also be processed by cutting, grinding, drilling, etc. within a certain hardness range. The diversity of processing makes the applicability of polyurethane elastomers very wide, and the application fields continue to expand.
4. Oil resistance, ozone resistance, aging resistance, radiation resistance, low temperature resistance, good sound permeability, strong adhesion, excellent biocompatibility and blood compatibility. These advantages are the reasons why polyurethane coated wheel elastomers are widely used in military, aerospace, acoustics, biology and other fields.
