The advantages and disadvantages of big into analytical industrial core pu castor castor

Core polyurethane, polyurethane casters is bonded on the cast iron or steel core or steel core, has the characteristics of quiet, slow weight, economic, and can be widely used in most of the work environment, but core polyurethane casters are not perfect. Good pu castor load, good abrasion resistance, corrosion resistance, good shockproof performance, castor material choice of materials. Usually the size of the industrial casters in 4 ~ 8 inches ( 100 - 200毫米) Between material polyurethane wheel optimal, wear-resisting performance is superior, the performance of the adjustable range is big, processing methods diversity, applicability widely, oil resistance, ozone resistance, aging resistance, radiation resistance, good low temperature resistance, good acoustic, stick relay is strong, good biological compatibility and blood compatibility. 1, performance, wide adjustable range. A number of physical and mechanical performance 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, polyurethane elastomer 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. Polyurethane elastomer 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. 2, wear-resisting performance is superior. 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. Metal materials such as steel, although very hard, but doesn't have to wear; Other rice huller rubber roller, such as milling, coal preparation with sieve sieve plate, stadium track the runway, forklift truck crane dynamic oil seal, elevator wheels and wheel roller skates, etc are also polyurethane elastomer. Need to mention here is that to improve the low and middle hardness, the friction coefficient of polyurethane elastomer parts, improve the bearing under the load of wear-resisting performance, can add a small amount of sulfide in this type of polyurethane elastomer aluminum and graphite or silicone oil lubricant. 3, processing methods diversity, wide applicability. Polyurethane elastomer 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. The applicability of the process, the diversity of the polyurethane elastomer is very extensive, application domain expands unceasingly. 4, 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 is polyurethane elastomer in military industry, aerospace, acoustics, and biology extensively in the fields of application. On the downside, endogenous heat is big, high temperature resistant performance, especially wet and heat resistance is not good, not resistant to strong polar solvent and strong acid and alkali medium.
