Four elements of formula design for recycled rubber products 2

"Reasonably design the formula of recycled rubber products." This sentence has no idea how many times it has been mentioned, but it is actually very difficult to make it. In the formulation of recycled rubber products, the use of compounding agents can not only improve product performance, but also reduce costs; but improper mixing between the compounding agents will not only reduce the overall performance of rubber products, but also increase the cost budget of recycled rubber products. Therefore, when designing the formula of recycled rubber products, rubber product manufacturers must consider the interaction between the additives to control the cost of raw materials and product performance.

3. Consider interactions between complexing agents

Reasonable selection of compounding agents in the formulation of recycled rubber products can improve various indicators of the products. During processing, the compounding agent will not only react with the rubber compound, but also react between the compounding agent and the compounding agent. When selecting compounding agents for reclaimed rubber, rubber product manufacturers must consider the interaction between the compounding agents, which is "synergistic" or "antagonism", "symbiotic" or "phase grams", to avoid the counteracting effect between the compounding agents affecting regeneration Mechanical strength and other indicators of rubber products. The same compounding agent has different effects in different recycled rubber compounds. Rubber product manufacturers must adjust the type and dosage of the compounding agent according to the characteristics of the compound and the role of the compounding agent.

4. Consider the cost budget of rubber products

The biggest purpose of using recycled rubber is to reduce the production cost of rubber products. Therefore, when designing the formula of recycled rubber products, we must calculate the cost and choose the appropriate compounding agent according to the cost budget. In general, when using low-cost recycled rubber such as ordinary tire recycled rubber, sole recycled rubber and other products to produce low-grade rubber products, the use of high-priced reinforcing agents and fillers 2LLYY0102 is not appropriate. Rubber product manufacturers need to combine rubber cost, processing cost, and performance requirements of recycled rubber products, and reasonably choose compounding agents, especially those with less rubber volume, high energy consumption, and low output.

At present, with the continuous upgrading and development of production technology and equipment for recycled rubber, there are more and more types of recycled rubber, the quality of recycled rubber is getting better and better, and the application of recycled rubber is more and more. Many times it can completely replace the original rubber. However, rubber product manufacturers still need to strictly follow the above principles when designing the formula of recycled rubber products, taking into account the use occasions of recycled rubber products, their own production processes and equipment conditions, cost budgets, and the interaction between compounding agents to reasonably determine the The blending ratio and the type and amount of the compounding agent in the formula can ensure the maximum quality and reduce the cost.
