What is the Way to Improve the Yield of Butyl Rubber Stoppers?

Jun. 17, 2021

As a Bromobutyl Rubber Stopper Supplier, let me share with you.

Butyl rubber stoppers processed with butyl rubber have good air tightness and high chemical stability. They have replaced a large number of natural rubber bottle stoppers and occupy a large share of the market; reclaimed rubber is a new raw material that reduces the quality of rubber products and improves The incorporation rate of butyl rubber stoppers can further reduce waste of resources and improve production efficiency while reducing costs. So, how can we improve the yield of butyl rubber stoppers containing reclaimed rubber?

1. Pay attention to impurities

When using butyl rubber and butyl reclaimed rubber to produce butyl rubber stoppers, you must choose a rubber with high cleanliness, especially the reclaimed rubber processed from waste butyl rubber products as raw materials to ensure the finished butyl rubber stopper. It 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 is necessary to pay attention to the "not falling" of the butyl rubber. Once the material is stained with impurities, it will be brought into the butyl rubber stopper; clean the production environment in time to ensure cleanliness.

2. Pay attention to the amount of water added

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 vulcanization conditions

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 vulcanization will also cause wrinkles on the surface of the butyl rubber/reclaimed rubber stopper. Rubber products enterprises must reasonably control the vulcanization time and vulcanization pressure during the processing process, adjust the vulcanization speed, accurately grasp the rubber simmering and deflation time, and improve the yield of butyl rubber stoppers.

4. Pay attention to the clamping operation

Mold clamping is a necessary process in the processing of butyl rubber stoppers. If there is a problem of offset during the mold 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, and the position should be placed when the mold is closed. positive.

In the production process of butyl rubber stoppers, there are still many problems that need to be paid attention to to improve the yield. For example, if the mixed butyl rubber is parked for too long, it will cause a large amount of water inside the rubber to evaporate, and bubbles will appear on the surface of the butyl rubber stopper. Reasonably control the parking time of the rubber compound.
