Key points for selection and feature selection when purchasing rubber wheels
Time：Aug 24,2022
Key points for selection and feature selection when purchasing rubber wheels: 1. The weight the wheel needs to bear; the purchased wheel should exceed this weight to increase the lifespan of the wheel. 2. The usage environment of the wheel; use smooth wheels for smooth surfaces and textured wheels for uneven surfaces, with a channel-type iron core. 3. For light loads, choose smooth wheels; for heavy loads, choose textured wheels with a channel-type iron core. 4. Quality selection: wheels should have elasticity and hardness; otherwise, they are prone to rubber peeling and delamination, making them expensive in the long run despite being cheap to buy. Heavy-duty wheels must have a channel-type iron core and textured rubber to ensure a long lifespan and cost-effectiveness. Regardless of the wheel model, if it lacks elasticity and hardness, the quality will not be good. Basic characteristics of rubber wheels: 1. When rubber products are molded, they are subjected to high pressure, and the cohesive force inherent in the elastomer cannot be eliminated. Upon demolding, they often experience highly unstable shrinkage (the shrinkage rate of rubber varies with the type of rubber), and it takes some time to stabilize. Therefore, when designing a rubber product, whether in terms of formulation or mold, careful calculations and adjustments are necessary; otherwise, it can lead to unstable product dimensions and poor quality. 2. Rubber is a thermosetting elastomer, while plastic is a thermoplastic. Due to the different types of vulcanization agents, the temperature range for molding and curing rubber can vary significantly, and it can even be affected by changes in climate and indoor temperature and humidity. Therefore, the production conditions for rubber products need to be adjusted appropriately at all times; otherwise, it may lead to variations in product quality.
