There are many types of carbon black, and the uses of different carbon blacks will be different, but we must understand that no matter what purpose carbon black is used for, we need to figure out what type and characteristics of carbon black are suitable for it. to the best use. In this way, we can choose carbon black according to our needs. The following will introduce how to choose carbon black and carbon black selection skills.
How to choose carbon black for coloring
Choose carbon black with high blackness and small particle size, but it must be ensured that the carbon black is reasonably and completely dispersed, otherwise it will run counter to the original requirements. Now the carbon black used for coloring is divided into one category called pigment carbon black. You can directly choose pigment carbon black for the carbon black you want to use for coloring.
How to choose carbon black for color matching
The carbon black used for color matching is different from that used for coloring. The coloring requirements are higher. The carbon black used for color matching can choose carbon black with low blackness, large particle size and easy dispersion.
How to choose carbon black for UV resistance
Anti-ultraviolet carbon black is mainly used in plastics and rubber and plastics. Choose carbon black with medium particle size and slightly higher structure, and their anti-ultraviolet performance is the best.
How to choose carbon black for conductivity
The carbon black used for conductivity should choose good conductivity, such as conductive carbon black, acetylene carbon black and so on.
Principles of Carbon Black Selection Skills
1. Choose according to the characteristic requirements of the product. Appropriate carbon black varieties can be selected, such as super wear-resistant super wear-resistant, high wear-resistant furnace black, etc., which can give the tread excellent wear resistance; acetylene carbon black and other conductive carbon black can make the vulcanized rubber conductive; To design a product that has a certain strength but needs to maintain a certain flexibility, semi-reinforcing carbon black can be used;
2. Select according to the process operation requirements of the rubber type and products used. In addition to considering the characteristic requirements of the product, the properties of the rubber used and the performance requirements of the product must be considered at the same time to properly select the carbon.
