How to Improve the Yield of Butyl Rubber Stoppers?

As a Rubber Stopper Manufacturers, share with you. 90% of the packaging rubber stoppers in the world are produced with butyl rubber as the base material. The butyl rubber stopper made of butyl rubber as the main raw material has good air tightness, high chemical stability, good heat resistance, good acid and alkali resistance, and high internal cleanliness. It has replaced a large number of natural rubber bottle stoppers in the market. Reclaimed rubber is a new type of raw material to reduce rubber products. Increasing the yield of butyl rubber stoppers mixed with reclaimed rubber can further reduce resource waste and reduce cost input while improving production efficiency. How can butyl rubber stopper manufacturers improve the yield of butyl rubber stoppers containing reclaimed rubber during the production process?

Bromobutyl Rubber Stopper

1. Water volume problem

In the process of using butyl rubber/reclaimed rubber to produce butyl rubber stoppers, if too much water is added, it will cause problems such as bubbles on the surface of the butyl rubber stopper. Therefore, you must pay attention to the amount of water added during the mixing of butyl rubber. Control within the prescribed dosage range. 3. Pay attention to the curing conditions

2. With or without impurities

When using butyl rubber and producing butyl rubber stoppers, choose a rubber with high cleanliness, especially reclaimed rubber processed from waste butyl rubber products to ensure that the finished butyl rubber stopper does not contain any impurities Generally, the butyl reclaimed rubber after 80 mesh filtering and refining has good fineness and almost no impurities; in the production process of butyl rubber stoppers, it must be noted that the butyl rubber "does not fall to the ground". Once the rubber is stained Impurities will be brought into the butyl rubber stopper; clean the production environment in time to ensure cleanliness.

3. Conditions of vulcanization

Vulcanization is one of the main processes in the production of rubber products. The effect of vulcanization directly affects the yield of butyl rubber stoppers. During vulcanization, insufficient vulcanization pressure, insufficient rubber material, and excessive vulcanization speed will cause partial lack of glue on the surface of butyl rubber stoppers, or There are bubbles on the surface; excessively fast vulcanization speed, too long simmering and deflation time during molding and vulcanization will also cause wrinkles on the surface of the butyl rubber/reclaimed rubber stopper. In order to improve the yield of butyl rubber stoppers, rubber products enterprises must reasonably control the vulcanization time, vulcanization pressure, adjust the vulcanization speed, and accurately control the rubber simmering and deflating time during the processing.

4. Is the clamping operation standard?

Mold clamping is a necessary process in the processing of butyl rubber stoppers. If there is a problem of offset during the clamping operation, it will definitely cause partial lack of glue in the butyl rubber stopper. Therefore, the mold clamping operation should be cautious and careful. positive.
