Introduction

Carbon black is a kind of black particulate matter formed by carbon, which has many special properties and a wide range of uses.

Nature:
1. The color is dark and thick. Due to the large surface area and strong light absorption ability, carbon black can absorb and scatter light to make it appear black.
2. The structure is loose and porous, with a large specific surface area, so it has good adsorption performance.
3. carbon black is amorphous, amorphous structure.
4. relatively high temperature resistance, melting point and thermal decomposition point are higher.

Use:
1. rubber industry: carbon black is an important additive in the rubber industry, which can increase the strength, hardness and wear resistance of rubber and improve the physical properties of rubber products.
2. printing ink: carbon black can be used as the pigment of the ink, giving black to the ink, and also improving the gloss and color vividness of the printed product.
3. Coating industry: Carbon black can be used to prepare black coatings to improve the uniformity and weather resistance of the coatings.
4. cosmetics industry: carbon black is commonly used as a pigment in cosmetics, such as eyeliner, mascara, etc.
5. Battery industry: Carbon black is one of the important components of battery cathode materials, which can improve the conductivity and energy storage capacity of batteries.

Preparation Method:
There are mainly coal combustion method, coal slurry method and natural gas cracking method.

Safety Information:
1. Carbon black is a non-combustible substance, but it may produce toxic gases at high temperatures.
2. long-term exposure to carbon black may cause skin and respiratory tract irritation, it is recommended to wear protective gloves and masks when using.
3. avoid inhalation or contact with eyes, such as accidentally contact with eyes or skin, should immediately rinse with plenty of water, and medical treatment.
4. when storing carbon black, it should be kept away from fire and oxidant, and the storage environment should be dry and well ventilated.
