The use of tire recycled rubber to reduce the cost of rubber gaskets need to pay attention to what issues
The function of the rubber gasket is to protect the closed surface of the inner tire from the rim wear. It is placed between the inner tire and the rim, which directly affects the service life of the car tire.Shanxi cushion belt wholesaleThe manufacturer stated that in actual production, the rubber gasket can be completely used with natural rubber, or used with butadiene rubber and styrene butadiene rubber, and tire recycled rubber can also be used to significantly reduce raw material costs. In the production process of rubber products, the rational use of tire recycled rubber can achieve the dual purpose of reducing costs and ensuring quality. So, what problems should be paid attention to when using tire recycled rubber to reduce the cost of rubber gaskets?
1. Application of tire reclaimed rubber in rubber cushion belt.
The recycled rubber of waste tire processing has good compatibility with natural rubber, styrene butadiene rubber, butadiene rubber and other general rubber, and can be directly mixed with rubber pad production formula. At present, tire recycled rubber can be used with natural rubber, tire recycled rubber/natural rubber/butadiene rubber, 2YLYY31-MXF and natural rubber/styrene butadiene rubber, even tire recycled rubber/natural rubber/butadiene rubber/styrene butadiene rubber; According to the actual needs of rubber pads, choose a production mode that is more suitable for cost and performance.
2. How to choose tire regeneration choice rubber cushion belt.
Tire recycled rubber can be divided into tread recycled rubber, all-tire recycled rubber, sidewall recycled rubber, etc. According to the fineness, it can be divided into ordinary recycled rubber (30-40 mesh), fine recycled rubber (60 mesh) and ultra-fine tire recycled rubber (80 mesh or higher). When using tire recycled rubber to reduce the production cost of rubber pads, in order to ensure the mechanical strength of the pads, rubber product manufacturers can choose higher effective rubber hydrocarbons. The finished pads have high mechanical strength, good wear resistance and long service life.; Choose recycled rubber with 60 mesh or higher fineness to ensure that the surface of the rubber pad is smooth and bright, and avoid bubbles or impurities in the finished pad.
3. Reasonable control of rubber pad with the amount of tire reclaimed rubber.
Product quality is the foundation of the enterprise. In actual production, only by selecting the appropriate tire recycled rubber and reasonably controlling the amount of tire recycled rubber in the cushion belt formula can the product quality be guaranteed. Generally speaking, when tire recycled rubber and natural rubber are used together to produce rubber cushion belts, the addition amount of tire recycled rubber in 100 parts of natural rubber should be controlled between 200-250 parts; When tire recycled rubber is used together with natural rubber/styrene butadiene rubber, the addition amount of tire recycled rubber in 100 parts of original rubber shall not exceed 150 parts; When tire recycled rubber is used together with natural rubber/butadiene rubber, the addition amount of tire reclaimed rubber in 100 parts of raw rubber should be controlled at 150-180 parts.
When using tire recycled rubber to reduce the production cost of rubber gasket, rubber product manufacturers need to choose the appropriate application method, select tire recycled rubber according to actual needs, and reasonably control the amount of recycled rubber to lay a good foundation for the production of rubber gasket. basis. In addition, when tire recycled rubber reduces the production cost of rubber pads, it is also necessary to appropriately adjust the rubber product formula to further optimize the quality of the finished product and reduce more production costs while ensuring quality.
