Why Add Carbon Black To The Rubber Sheet?

Company NewsTel:+86-19803278181


Plywood is a mixed rubber made of rubber as raw material and mixed by a dense mixer. 

The formula is constructed when mixing the rubber according to the characteristics of the required plywood, to determine the hardness of the products required. 

The product is made by the rubber plate vulcanization machine molding. 

After the product is formed, the flying side is processed to make the product surface smooth and without burr.

In order to meet some requirements in rubber plate production, often used with carbon black. The following problems should be noted when using carbon black:

1. Different performance requirements. 

For example, the sulfide gel using fine-grain furnace charcoal black has a high tensile strength, constant elongation stress and hardness, and good wear resistance. 

Better elasticity can be obtained by using the channel carbon black. 

These two benefits can be achieved by combining the two.

2. Convenient for process operation. For example, although the channel carbon black has good amplification performance, its processing performance is poor. 

The combination of quick squeeze and semi-reinforced furnace black can often improve the process and facilitate the operation.

3. Reduce costs. 

Such as the large use of cheap sprinkler black, hot crack carbon black and semi-reinforced furnace black and other varieties, can achieve the purpose of reducing the cost.
