Rubber products are diverse, different shapes, thickness varies, in which the smooth and bright surface of rubber products is to determine whether the products contain air bubbles is an important parameter, but the surface does not have air bubbles on behalf of the rubber products qualified? Of course not, for thick products, if the production process is not operating properly such as under pressure, under sulfur, will cause the formation of porous products inside the state, and these rubber products with a smooth appearance and easy to flow into the market, so rubber thick products in the production process must be careful to prevent under pressure, under sulfur.
Rubber thick products vulcanisation if the vulcanisation pressure is small or the holding time is too short, the pressure in the mould cavity is insufficient, resulting in rubber, compatibility agents and volatile substances generated in the production process is difficult to remove, the formation of micropores in the thick products, directly affecting the use of rubber products and service life.
Oversulphur refers to the vulcanisation of rubber products vulcanisation time and the degree of vulcanisation beyond the normal range, the finished product indicators will be significantly reduced, many rubber thick products manufacturers in order to reduce the vulcanisation time, to prevent the products of the outer layer of the rubber oversulphur will be in the rubber for the full vulcanisation of the products before the mould, at this time the thick products have been formed outside the vulcanised rubber shell, but the thick products inside the rubber shell, the vulcanised rubber shell.
The rubber shell of the thick products, but the thick products inside is often due to lack of sulfur and bubbles; therefore, thick products in the vulcanisation must ensure that the rubber is fully vulcanised, fully crosslinked, to avoid internal undersulfurisation, the quality of thick products have an impact.

Rubber thick products in the production process within the lack of rubber, under pressure, under sulfur problems are difficult to find, so improve the rubber products processing technology, reasonable adjustment of rubber products formula, to avoid these difficult to find but the quality of rubber thick products and have a fatal impact on the occurrence of the problem of thick products to improve thick products yield, improve the quality of thick products
It is of great significance to improve the yield of thick products and improve the quality of thick products.
It is of great significance to improve the yield of thick products and improve the quality of thick products.
Reclaimed rubber is waste rubber products processed into products, used in the production of thick products must choose dense texture, no impurities in the reclaimed rubber products, strict control of the production process conditions, and reasonable adjustment of the reclaimed rubber thick products formulations, in particular, reclaimed rubber products formulations of the sulphurising agent, accelerator dosage (reclaimed rubber itself contains sulfurising agent and other agents that have not been completely separated out), to avoid the lack of pressure, lack of sulphur on the quality of reclaimed rubber thick products have a bad impact. Avoid the bad influence of underpressure and under-sulphur on the quality of thick products of recycled rubber.
