In actual production, there are many factors that lead to excessive flashing of chlorobutyl rubber stopper, such as molds, raw materials, process operations, etc., may cause flashing of chlorobutyl rubber stopper.
① From the perspective of the mold, reasonable design of the mold structure, accurate tapping line, and timely cleaning of the mold can improve the problem of excessive burrs;
②From the raw materials, check which raw materials have been replaced before the problem of excessive burrs, or whether the amount of sulfur and accelerators is unreasonable (generally, when the chlorobutyl rubber stopper is taken out of the mold, the amount of sulfur needs to be reduced to improve the resilience of the product. If it is poor, you need to increase the amount of sulfur or accelerator M);
③From the point of view of the production process, too low mold temperature and excessive exhaust will also lead to excessive burrs. Therefore, the burrs should be quickly removed after each mold is completed to avoid more chlorobutyl rubber stoppers with poor quality.
Reclaimed rubber, as a renewable resource for recycling and reprocessing waste chlorobutyl rubber stoppers, has a great advantage in price, but there is indeed a certain gap with the original rubber in some indicators and performances, but this does not mean that the production of chlorobutyl rubber stoppers appears All the problems are caused by hb reclaimed rubber. We must look at the advantages and disadvantages of reclaimed rubber rationally and objectively, and don't attribute all problems to reclaimed rubber. There are burrs in the production of chlorobutyl rubber stoppers using reclaimed rubber. Chlorobutyl rubber stopper manufacturers should investigate the reasons one by one, choose the appropriate deburring method, and produce more high-quality chlorobutyl rubber stoppers.
