How big is the performance of the pu castor adjusting range

How much the performance of the pu castor adjusting range, the performance of the wide adjustable range. A number of physical and mechanical performance indexes can be adjusted through the selection of raw materials and formulations, within a certain range of change, to meet the different requirements of users on the product performance. Superior wear resistance. Especially in the presence of water, oil and other wetting medium work conditions, its wear resistance is often several times to dozens times of ordinary rubber materials. Metal materials such as steel, although very hard, but does not have wear-resisting, polyurethane (pu) round the mouth of the elastomer coating and the continuous running 1800 small ring and skirts into still not wear. Processing methods diversity, wide applicability. Round polyurethane elastomer can be the same as general rubber plastication, mixing, vulcanization molding process; Also can be made into liquid rubber, also can be made into granule material, like common plastic, with injection molding, extrusion, calendering, blow molding process. 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. Caster wheel bearing ability, also known as dynamic load in caster wheel dynamic load is different due to the test in a different way of the factory, material of the wheel will have different and different, the key is to support the structure and quality can impact and shock resistance. When equipment has fundamental impact or vibration of the castor instantaneous load bearing capacity. Static load and static load static load and static load: castor can bear the weight of the under stationary state. Static load generally should exercise load ( Dynamic load) 5 ~ 6 times, static load should be at least 2 times the impact load. Industrial casters, especially in the presence of water, oil and other wetting medium work conditions, its wear resistance is often several times to dozens times of ordinary rubber materials. Metal materials such as steel, although very hard, but does not have wear-resisting, such as the Yellow River irrigated area of large water pump, the flow components through a large amount of sediment scouring metal ring and skirts, in less than a few hundred hours serious wear is leaking, and use the mouth of the polyurethane elastomer coating is the continuous running 1800 small ring and skirts into still not wear. Other rice huller rubber roller, such as milling, coal preparation with sieve sieve plate, universal wheel stadium track the runway, crane forklift 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.
