High elastic pu castor widely used in the field of industrial reason is what?
A number of physical and mechanical properties of the pu castor indexes can be adjusted through the selection of raw materials and formulations, flexible changes within a certain scope, so as to meet the unique requirements of users on the product performance. Such as hardness, is often the user an important index of products, pu castor can be made into Shao Er A hardness of the 20 or so soft printing rubber roller, and can be made more than 70 Shao Er D rigidity rolling roller, this is the general elastomer material is difficult to do, can suit the needs of different users. High elastic pu castor widely used in the field of industrial reason is what? Pu castor is composed of many flexible chain segment and rigid chain segments of the polarity of polymer materials, with the improvement of rigid chain segment ratio and the increase of density of polar group, elastomer original strength and hardness will be increased accordingly. In the presence of water, oil and other wetting medium work conditions, the wear resistance of polyurethane casters are often several times to dozens times of ordinary rubber materials. Pu castor metal materials such as steel, although very hard, but does not have wear-resisting; Other luxury valley such as milling machines, rubber roller for coal preparation of vibrating sieve sieve plate, track the runway of the sports ground, forklift truck crane dynamic oil seal, elevator and early skates chakras and so on are also pu castor comes in. Need to mention here is that to improve the friction coefficient of low hardness, high elastic polyurethane casters, improve the bearing under the load of wear-resisting performance, can add a small amount of sulfide in this type of pu castor aluminum and graphite or silicone oil lubricant. High elastic pu castor processing methods diversity, applicability wide. Pu castor can be the same as general rubber plastication, mixing and vulcanization process molding ( The MPU) ; Also can be made into liquid rubber, mould pressing or spraying, sealing, centrifugal casting molding ( The CPU) ; Can also be made from grain, like common plastic, use process such as injection, extrusion, calendering, blow molding, The CPU) 。 Mold or injection molding parts, within a certain range of hardness, cutting, grinding, drilling and other mechanical processing. Pu castor processing craft process, the diversity of the applicability of the pu castor is very extensive, application domain expands unceasingly. Oil resistance, ozone resistance, aging resistance, radiation resistance, good low temperature resistance, good acoustic, stick relay is strong, good biological compatibility and blood compatibility. These advantages are hengshui teng kai new materials technology co. , LTD production of polyurethane casters in military industry, aerospace, acoustics, and biology extensively in the fields of application.
