The role of vulcanized rubber powder in the production of rubber products

Vulcanized rubber powder is a powdery elastomer formed by vulcanized rubber under the action of mechanical force or by using low-temperature freezing method. The raw material of vulcanized rubber powder is the waste rubber product and the scrap produced during the production process of rubber products. ; is one of the main ways of waste rubber treatment. At present, many vulcanized rubber powders are recycled to the rubber products industry. What role does vulcanized rubber powder play in the production of rubber products?

1. Vulcanized rubber powder reduces the production cost of rubber products

At the beginning of the article, we have already mentioned that vulcanized rubber powder is the product of recycling and processing of waste rubber and waste rubber products. As a typical renewable resource, vulcanized rubber powder products are very low in price and can usually be filled as rubber fillers in rubber products. Increasing the volume of the product to reduce the production cost; the vulcanized rubber powder is a typical powdery rubber elastomer, which can be used as a main rubber material in the production of rubber products. For example, the rubber sole can be mixed with more than 100 parts of vulcanized rubber powder. Rubber floor tiles can be completely used with vulcanized rubber powder, which significantly reduces raw material costs.

The main purpose of using vulcanized rubber powder in the production of rubber products is to reduce production costs.

2. Vulcanized rubber powder can improve the process performance and performance of rubber products

In actual production, the amount of vulcanized rubber powder in rubber products with different indexes varies greatly. In general, high-grade rubber products can be mixed with ultra-fine rubber powder with fineness of more than 80 mesh to improve the tear resistance of rubber products. And fatigue resistance, experience has shown that the use of 5-10 parts of 100 mesh ultra-fine rubber powder in the tire tread rubber can significantly improve the mileage of the tire; in the production of extruded rubber products with appropriate amount of vulcanized rubber powder It can reduce the deformation of semi-finished products, improve the extrusion performance of the rubber and facilitate the exhaust. The use of vulcanized rubber powder also improves the fatigue resistance and crack growth resistance of rubber products.

3. The effect of vulcanized rubber powder in rubber products

Studies have shown that the use of a large amount of vulcanized rubber powder will affect the mechanical strength and wear resistance of rubber products to a certain extent, and the higher the fineness of vulcanized rubber powder is used in rubber, the tensile strength and elongation of vulcanized rubber The closer the abrasion is to the vulcanizate without added rubber powder; the finer the rubber powder added in the production of rubber products, the better the comprehensive index of rubber products.

The production experience of numerous rubber products manufacturers tells us that vulcanized rubber powder has an irreplaceable role in the production of rubber products. Reasonable use of vulcanized rubber powder can not only reduce production cost, but also improve the process performance of rubber products, improve the performance of rubber products and prolong the use.
