Carbon black, also known as carbon black, is an amorphous carbon, a light, friable, and very fine black powder with a very large surface area surface area between 10-3000 m2/g and a specific gravity of 1.8-2.1. It is an indispensable chemical raw material in industry. The process of carbon black production is different,the chemical properties of the surface area are also different, for a certain concentration of carbon black, the finer the carbon black, the higher the degree of light absorption, the intensity of its coloration also with the primary particle size particle size and structure of the reduction and increase.

Classification of soot

1 、 in accordance with production, it is mainly divided into lamp,Gas, stove and slit soot.

2 、 depending on use, it is divided into a pigment soot,I sit for rubber conducting soot and special soot.

3 、 in accordance with the function, it is mainly divided into reinforcing technical carbon staining technical carbon, conducting technical Carbon and so on.

Investment prospects of soot

1, in the rubber industry, soot used in the rubber industry is more than 90% of the total production of soot, is mainly used for various types of tires.

2, in the ink industry, soot is the main raw material of black printed paint, modern ink basically use high -quality pigment soot.

3, in the paint and varnish industry, soot with paint, with small reactivity, high blackness, good weather, staining speed, and so on.

4, in the plastic industry filled with soot plastic, thermal deformation is small, the size of the product changes, it can improve its rigidity, hardness, electrical conductivity, thermal conductivity and corrosion resistance.

5, other areas of application, soot is also used in dry batteries, carbon products, electrical and electronic components, solid alloys, graphite of high cleanliness, printing and dyeing, electrostatic photography, photography, gunpowder, cement, skin, lubrication, casting and other sectors Sectors, in these sectors, soot dosage are small, but often play a large role.

The process of production of soot

After dehydration and preliminary heating of raw material oil, it evaporates or half -gaps into the reactor, natural gas or gas under pressure, it is transported to the soot reactor, from tangential injection, air under the pressure of the air vent, in the air heater, so that it previously heats up to 350 degrees of Celsius in Celsius. The reactor for spraying raw materials and burning with drops of raw material oil at 1500-1600 degrees Celsius, high-temperature burning of residual gas, through a series of heat-volume equipment, chilled up to 450 degrees Celsius, is sent to the cyclone separator and hose filter, so soot and residual gas gas are separated, The exhaust of the sleeve filter can be used as a boiler fuel for the production of steam or a turbine drive for electricity generation. After a seat machine to remove impurities, by the air supply system to the granulation granulator, according to the conveyor and bucket elevator through the magnetic separator, and then goes to the hopper for storage of soot.
