Carbon Black Chemical Properties,Uses,Production

Production method

Natural gas tank method of making carbon black: take natural gas as raw material and use iron pipe to send it into the combustion chamber. The form of the combustion chamber can be either long and short and is made of iron plate. It contains a number of olefin burner inside it. Natural gas is sprayed with appropriate force from the burner nozzle and burned in the case of insufficient air, that is, to generate a bright and black smoke flame. The flame then goes directly into the channel iron with the distance between the burner and the slot surface being 65~80 mm. At this time, the temperature of olefin burning is reduced from about 1000 to 1400 ° C to about 500 ° C, and the carbon black is accumulated. The groove can move back and forth horizontally, with a moving speed of 3 to 4 mm/s. In order to maintain normal production, the required amount of air is about 2.5 to 3 times the theoretical calculation. The resulting carbon black was scraped into a funnel with a fixed doctor blade and sent to a central packing chamber for disposal. Then the carbon black is softened, filtered to remove the hard particles and scale and further sent into the mill grinding to enable more uniform thickness. However, the body is still very light and loose, thus should be shaken to a become a bit solid. Then add a small amount of water to the carbon black to make it into paste-like shape and have a small needle rotated inside it to forming micro-pellets, followed by drying to obtain the finished product. In the case of using pigment for carbon black, in order to facilitate the dispersion, the granulation is unnecessary. The process is as follows:
Raw gas, air → combustion cracking → collection → granulation → packaging → finished product.
Carbon black is one of the oldest industrial products. In ancient times, china has already applied incomplete combustion of vegetable oil for making pigment carbon black. In 1872, the United States first used natural gas as raw material to produce carbon black using tank method and mainly used it as a coloring agent. It was not until 1912 when Mott found the reinforcement effect carbon black on the rubber before the carbon black industry had gotten rapid development. Then it had successively developed of a variety of process methods. At present, oil furnace method is the most efficient and most economical method with the oil furnace black production amount accounting for  70-90% of the total carbon black production. There are mainly furnace, slot method, thermal cracking, three methods.
It is obtained by the carbonization of the plant material such as peat. It can also be derived from the carbonization of cocoa shell and beef bone or from the combustion of vegetable oil.

Uses

1.  It is edible black pigment. It can be used for pastry with the usage amount of 0.001% to 0.1%.
2.  It can be used for food coloring agent. China provides that it can be used for rice, flour products, candy, biscuits and pastries with the maximum usage amount of 5.0g/kg.
3.  Rubber industry uses it as a reinforcing filler. 2. Paint Inks applies it as coloring pigments in paint inks. 3. Used for the manufacturing of black paper such as packaging materials for photographic materials and the black paper made of high-conductivity black carbon in the radio equipment. 4. Carbon paper and typewriter; it is used when it is required for darker colors and can remain on the carrier. 5. Plastic coloring, ink, phonograph records, shoe polish, paint cloth, leather coatings, colored cement, electrodes, electronic brushes, batteries and so on.
4.  As electric conductive agent of lithium ion battery;
5.  Mainly used for rubber, paint, ink and other industries;
6.  Used for the reinforcement of car tread and sidewall, hose, groove, industrial rubber products as well as conveyor belt.
7.  Used for tire tread, surface tire repair, automotive rubber parts, conveyor belts, conveyor pads, etc., The vulcanized glue of this carbon black shows excellent tensile strength and abrasion resistance
8.  It is mainly used for the reinforcement of tire belt, sidewall, solid tires, outer layer of roller, hose surface, industrial rubber products and car tire tread.
9.  It is used for the reinforcement of the tire tread of car and truck, surface of conveyor belt and industrial rubber products.
10.  For rubber reinforcement, coloring agent, metallurgy, rocket propellant
11.  For rubber products to fill and reinforcement.
12.  For rubber products, carcass, valves and other filling .
13.  For paints and inks, plastics and other industries.
14.  Mainly used for raw materials of battery as well as for conductive and anti-static rubber products.
15.  In the rubber industry, it is used as the reinforcing agent and filter for the manufacturing of natural rubber and butyl rubber, being able to endow the vulcanized rubber with excellent tensile strength, elongation and tear resistance and so on. It should be mostly used for natural rubber-based large-scale engineering tires and a variety of off-road tires as well as being used for carcass and sidewall. In addition, it can also be used for high-strength conveyor belt, cold rubber products and drilling device. In light industry, it can be used as the filter of the paint, ink, enamel and plastic products.

Identification test

Solubility: being insoluble in water and organic solvents (OT-42)
Heated to red, burning without flames.

Content analysis

The sample was pre-dried at 120 ° C for 4 h and then measured by an instrument such as a C.H. O analyzer or subject to combustion/gravimetric analysis.

Toxicity

ADI has not yet been specified. It is listed as substance allowed to be in temporary contact with food, (FAO/WHO, 2000). It can not be digested and absorbed, so oral administration should be non-toxic, but given the incorporation of 3, 4-benzopyrene during the carbonization, it is basically not used now.

Use the limit

GB 2760-1996: Confectionery, biscuits, pastries, rice and flour products, 5.0 g/kg.
EEC provides for being used for concentrated fruit juice, jam, jelly, fruit wine.

Chemical properties

It appears as black powdery particles with a particle size of 0 to 500 μm. The relative density is 1.8 to 2.1. It is insoluble in water and organic solvents.
