V-belt is a conveyor belt with a V-shaped structure. It is mainly used in mechanical equipment that needs to transmit force. It has high transmission efficiency and low noise. Traditional rubber V-belts generally use natural rubber, styrene butadiene rubber or neoprene. The biggest role of latex reclaimed rubber in the rubber products industry is to replace natural rubber to produce various rubber products and reduce the cost of raw materials. In actual production, reclaimed latex rubber can be used in the production of rubber V-belts, achieving the dual effects of reducing costs and improving the quality of V-belts.
1. The role of latex reclaimed rubber in rubber V-belts
Compared with natural rubber and styrene-butadiene rubber, latex reclaimed rubber products are low in price, and used in rubber V-belt production can significantly reduce the cost of raw materials; latex reclaimed rubber is easy to mix with natural rubber, styrene-butadiene rubber, etc., and has good plasticity. Can reduce rubber power consumption. Latex reclaimed rubber has a small shrinkage, which can improve the dimensional stability of the V-belt; it has good vulcanization performance, and when used with natural rubber, it can reduce the probability of vulcanization and increase the vulcanization speed and scorch safety; the latex reclaimed rubber is stable and can be used in Improve the anti-aging performance of V-belt to a certain extent.
2. Usage of latex reclaimed rubber in rubber V belt
In actual production, latex reclaimed rubber can be used alone in the production of ordinary V-belts, or combined with natural rubber, or combined with styrene butadiene rubber, or natural rubber/styrene butadiene rubber/latex reclaimed rubber, natural rubber/styrene butadiene rubber /Neoprene/reclaimed rubber, natural rubber/neoprene/latex reclaimed rubber, etc. The combined use of rubber materials produces better performance and higher cost-effective rubber V-belts.
3. Selection skills of latex reclaimed rubber in rubber V belt
When using latex reclaimed rubber to produce rubber V-belts, rubber products manufacturers need to choose the closest latex reclaimed rubber to its specifications according to the actual performance requirements of the V-belt, and increase the amount of latex reclaimed rubber 2LLYY1013 as much as possible; when using latex reclaimed rubber to produce black rubber V-belts, Choose black latex reclaimed rubber (the price of black latex reclaimed rubber with the same index is lower) to reduce more raw material costs.
4. The amount of latex reclaimed rubber in the rubber V belt
Latex reclaimed rubber can reduce the raw material cost and production cost of rubber V-belts, and improve the processing performance of raw rubber. However, there is a certain gap between the physical and mechanical properties of reclaimed latex rubber and natural rubber. Rubber V-belts have strict requirements on the fatigue resistance, tear resistance and elongation of the rubber. It is necessary to reasonably control the amount of reclaimed latex rubber. In actual production, different rubber V-belts have different performance requirements, and the amount of latex reclaimed rubber needs to be adjusted appropriately.
Under normal circumstances: the rubber content of the V-belt covering layer rubber is controlled at about 50%, the ply rubber content is controlled at about 60%, and the compressed layer rubber is controlled at about 40%, so the latex in the compressed layer is regenerated The amount of rubber can be appropriately increased, which is determined according to the requirements of rubber V-belts and the rubber content of latex reclaimed rubber.
When using latex reclaimed rubber to reduce the raw material cost of rubber V-belts and improve the process performance of raw rubber, rubber products manufacturers also need to adjust the rubber V-belt production formula. Later, the editor will continue to discuss with you the rubber layers of rubber V-belts containing latex reclaimed rubber. Adding skill of compounding agent.
