Black cat ink black

The classification of various carbon blacks often involves the production methods such as channel black, furnace black and thermal black. It can also be classified according to the purpose, such as carbon black for rubber and carbon black for coloring. The naming principle of carbon black varieties is gradually formed during production and use. Initially, it is represented by the abbreviated letters of the English words of carbon black characteristics and production methods, such as HAF for high wear-resistant furnace black and MCC for medium pigment bath black. The American Society for Testing and Materials (ASTM) has issued a naming system that primarily stipulates the nomenclature of carbon black for rubber. At present, the ASTM naming system has been accepted by all countries in the world. It consists of a letter and three digits. The letter indicates the effect of the surface properties of the carbon black on the rubber processing process. The N indicates a normal vulcanized variety, and the S indicates a slowly vulcanized variety. The first number after the letter indicates the particle size of the carbon black. Based on the average particle diameter measured by electron microscopy, the particle size range of all carbon blacks was divided into 10 grades, the finest is 0 and the thickest is 9. The remaining two numbers are used to distinguish the difference in carbon black structure and performance. For example, the super wear-resistant furnace black can be expressed as SAF or N110; the high wear-resistant furnace black is represented as HAF or N330; the high wear-resistant high-structure furnace black is represented as HAF-HS or N347; the semi-reinforcing furnace black is SRF or N770. The easy mixing tank black is expressed as EDC or S300.

Black cat ink carbon black use

Carbon black is an important pigment after titanium dioxide. The annual consumption of rubber carbon black is about 6 million tons, and the special carbon black for coloring and other purposes is about 250,000 tons. The so-called special carbon black means that its use is "colored" or "conductive" rather than the reinforcement of rubber carbon black. Carbon black is manufactured by a precisely controlled production method, which can form about 50 different varieties, and 30 kinds are used in the rubber industry. There are more varieties of carbon black for coloring and other purposes, including dispersions of carbon black, masterbatches, conductive composites, slurries and lacquers.

Carbon black has the following qualities:

1. The best black pigment.

2. Almost the cheapest pigment.

3. The pigment with the strongest tinting strength and hiding power.

4. Visual sense is neutral.

5. The most stable pigment, heat, chemical and light resistant
