The butyl rubber plug processed with butyl rubber as the main raw material has good air tightness and high chemical stability. It has already replaced a large number of natural rubber stoppers in the market and has a very large share; reclaimed rubber is a new raw material for reducing rubber products. Increasing the yield of butyl rubber plugs with recycled rubber can further reduce resource waste and reduce production costs while improving production efficiency. So how do you increase the yield of butyl rubber plugs containing reclaimed rubber?
Pay attention to impurities
When using butyl rubber and butyl reclaimed rubber to produce butyl rubber stopper, it is necessary to choose a rubber compound with high cleanliness, especially reclaimed rubber processed from waste butyl rubber products to ensure the finished butyl rubber stopper. It does not contain any impurities. Generally, the butyl reclaimed rubber after 80 mesh filtration and refining has good fineness and almost no impurities. In the production process, the butyl rubber stopper must pay attention to the butyl rubber "not falling". Once the material is contaminated, it will be taken in a butyl rubber stopper; the production environment will be cleaned in time to ensure cleanliness.
2. Pay attention to the amount of water added
In the process of producing butyl rubber plugs using butyl rubber/recycled rubber, if too much water is added, there will be problems such as bubbles on the surface of the butyl rubber plug. Therefore, it is necessary to pay attention to the amount of water added during the mixing of the butyl rubber. Control in the specified dosage range.
3. Note the vulcanization conditions
Vulcanization is one of the main processes in the production of rubber products. The vulcanization effect directly affects the yield of butyl rubber plugs. When the vulcanization pressure is insufficient during vulcanization, the rubber is insufficient, and the vulcanization rate is too fast, the surface of the butyl rubber plug is partially deficient, or There are air bubbles on the surface; the vulcanization rate is too fast during the vulcanization process, and the helium gas and the deflation time are too long during the molding vulcanization, which may cause wrinkles on the surface of the butyl rubber/recycled rubber plug. Rubber products enterprises must reasonably control the vulcanization time, vulcanization pressure, adjust the vulcanization speed, accurately grasp the helium gas and venting time of the rubber compound, and improve the yield of butyl rubber plug.
4. Pay attention to the mold clamping operation
Clamping is a necessary process in the processing of butyl rubber plugs. If there is a problem of misalignment during mold clamping operation, it will cause partial weakness of the butyl rubber plug. Therefore, the mold clamping operation should be cautious and careful. positive.
Butter rubber plugs need to pay attention to many problems in the production process to improve the yield. For example, if the butyl rubber is used for a long time after mixing, the moisture inside the rubber will evaporate a lot, and bubbles will appear on the surface of the butyl rubber plug. Reasonable control of the mixing time of the rubber compound, we will not elaborate here.
The use of butyl reclaimed rubber in butyl rubber to produce butyl rubber plugs can ensure good air tightness, chemical stability, aging resistance of butyl rubber plugs, and also reduce the cost of some raw materials, if in the production process. Reasonable adjustment of butyl reclaimed rubber / rubber rubber plug formula, adjustment of vulcanization conditions, careful process operation, then it is possible to reduce the cost of investment.
