carbon black

الوصف

Carbon black (CAS no ********4), a form of amorphous carbon, is a kind of black pellet or powder and it mainly consists of carbon element. This material could be produced from the incomplete combustion or thermal decomposition of hydrocarbon compoud with solid, liquid, and gaseous state.

Carbon black can be used as a pigment in inks, coatings and plastics. For example, it could be added to polypropylene because it absorbs ultraviolet radiation which could cause the material to degrade.

Besides, used in reinforcing phase in automobile tires, this chemical could help conduct heat away from the tread and belt area of the tire, reducing the thermal damage and increasing tire life. Carbon black particles are also employed in some radar absorbent materials and in photocopier and laser printer toner. Carbon black from vegetable origin is used as a food coloring, and it is also known as additive E**3 in Europe.With its molecular formula of C and molecular weight of *2.*1, its systematic name of Carbon black is carbon. With the CAS registry number ********4, it is also named as Pigment black 6. With other registry numbers like **********9, **********4, it belongs to the product categories which are including Industrial/Fine Chemicals; Inorganic Chemicals; UVCBs-Organic; Activated Carbon; Packed GC and others. If you use and store it according to the specification, it will not decompose. When you need to store it, please keep it sealed in the storage vessel in the dry and well-ventilated place with its best storage life of one year to one year and half, or ensure that the workshop is equipped with ventilation or exhaust device. 

1. Properties
The other characteristics of this product can be summarized as: (1)EINECS: ********9; (2)Density: ~1.7 g/mL at *5 °C; (3)Melting Point: ***0 °C; (4)Boiling Point: ******0 °C; (5)Flash Point: >**0 °F; (6)Enthalpy of Vaporization: *1.*8 kJ/mol; (7)Vapour Pressure: *****0 mmHg at *5 °C.

2. Preparation
Carbon black could be produced from the following ways:

1. Natural gas channel process: Prepare the natural gas as the main material, and then go through the following list of chemical reaction: raw material gas, air-combustion and splitting-collecting-granulation-packing-finished product. And the chemical equation is as below: CnHm→nC+m/2H2↑.

2. HC(hydrocarbon): Hydrocarbon (natural gas, solid alkene) go through the process of incomplete combustion, splitting decomposition, or oxidation to produce this product.

3. Carbureted hydrogen method: Prepare the raw material of carbureted hydrogen with solid, liquid or gaseous state and then go through the process of incomplete combustion, splitting decomposition, or oxidation with defined amount of air in the considerate temperature. Among the three material, gas raw material is the best one. At the moment, the most used industrial way is as below: Firstly, prepare the material of natural gas, acetylene gas and anthracene oil, and secondly make it spout from the special nozzles mouth with pressure, and then go through the process of combustion, splitting and grinding to get this product.

3. Safety Information
When you are dealing with this chemical, you should be careful.

For one thing, this chemical is irritating to eyes and respiratory system and may may cause inflammation to the skin or other mucous membranes. For another thing, it is harmful which may cause damage to health.  Limited evidence of a carcinogenic effect. What's more, it is highly flammable which may catch fire in contact with air, only needing brief contact with an ignition source, and it has a very low flash point or evolve highly flammable gases in contact with water. When to be uses, it may form flammable/explosive vapour-air mixture.

According to the above dangers, you could take the following measures. You should wear suitable protective clothing and if in case of contact with eyes, rinse immediately with plenty of water and seek medical advice. And avoid contacting with skin and eyes and do not breathe dust while using.
