1. tire industry
Carbon black is an important chemical raw material, which is closely related to people's lives and is widely used in many fields. In these applications, the largest amount is rubber carbon black. Rubber carbon black accounts for about 89.5% of the total carbon black. Among rubber carbon black, tire carbon black accounts for about 67.5%; Nonrubber carbon black accounts for about 10.5%.
2. plastic industry
Carbon black for plastics accounts for a large proportion in the field of nonrubber applications. It can not only color or color but also prevent ultraviolet aging, antistatic or conductive.
The NC8310, NC8362, NC1270, NC5012, NC5011 and other carbon black produced by Nestor carbon black are widely used in Masterbatch, plastic film blowing, PCV color cake, cable shielding material, etc.
3. rubber products
Carbon black for rubber products accounts for about 20% of the whole carbon black industry and is widely used in the manufacture of automotive rubber products and other rubber products, such as rubber hoses, tapes, rubber shoes, etc.
The N330, N339, N550, N660, N774 and other carbon black products produced by Nestor carbon black are widely used in the production of rubber products.
It is impossible for the rubber industry to develop without the assistance of the carbon black industry; On the contrary, the carbon black industry cannot develop rapidly without the support of the rubber industry. Among the carbon black used in rubber, carbon black is used to make various types of tires, such as automobile tires, tractor tires, aircraft tires, power car tires, etc. The amount of carbon black in rubber is about 35-50% of that of raw rubber.
1. Existing packaging materials and specifications
25kg/ bag, made of kraft paper. It can also be packaged according to the packaging form and specifications provided by the customer.
2. Main physical and chemical properties of carbon black
Black granular amorphous solid, tasteless, specific gravity 1.82, ignition point >400 ℃, insoluble in water, non-toxic, stable chemical properties.
3. Hazard of carbon black
Non-combustible, flammable, corrosive, toxic, radioactive, oxidizing and dangerous goods.
Carbon black, also known as carbon black, is an amorphous carbon. It is a light, loose and very fine black powder with a very large surface area ranging from 10 ~ 3000m2 / g. it is the product of incomplete combustion or thermal decomposition of carbonaceous substances (coal, natural gas, heavy oil, fuel oil, etc.) under the condition of insufficient air. Those made of natural gas are called "gas black", those made of oil are called "lamp black", and those made of acetylene are called "acetylene black". In addition, there are "slot black" and "furnace black".
