Optimise the formula:The vulcanisation shrinkage performance of rubber can be optimised by adjusting the type and dosage of raw rubber species, fillers and auxiliaries.
Improve the process:By adjusting the process conditions such as vulcanisation temperature, time and pressure, the degree of vulcanisation and cross-linking density of the rubber can be controlled, so as to reduce the vulcanisation shrinkage.
Reasonable design of product shape and structure:By reasonably designing the shape and structure of products, the flow and shrinkage inhomogeneity during vulcanisation can be reduced, thus reducing the shrinkage rate. In summary, rubber vulcanisation shrinkage is a complex phenomenon, affected by a variety of factors. By optimising the formula, improving the process and reasonably designing the shape and structure of the products, the vulcanisation shrinkage can be effectively reduced and the quality and performance of rubber products can be improved.
