Carbon Black

WHAT IS CARBON BLACK?

Carbon Black is virtually pure elemental carbon in the form of colloidal particles that are produced by incomplete combustion or thermal decomposition of gaseous or liquid hydrocarbons under controlled conditions. Its physical appearance is that of a black, finely divided pellet or powder. Its use in tires, rubber and plastic products, printing inks and coatings is related to properties of specific surface area, particle size and structure, conductivity and color. Carbon black is also in the top 50 industrial chemicals manufactured worldwide, based on annual tonnage. Current worldwide production is about 18 billion pounds per year [8.1 million metric tons]. Approximately 90% of carbon black is used in rubber applications, 9% as a pigment, and the remaining 1% as an essential ingredient in hundreds of diverse applications.

Carbon black, which is also known as black soot, industrial soot, or carbon black, is basically the amorphous form of pure and paracrystalline carbon, which has a high surface area compared to its volume. This substance is produced by incomplete combustion or thermal decomposition of gaseous or liquid hydrocarbons under controlled conditions in the form of colloidal particles. Also, carbon black contains more than 95% pure carbon and the size of its black particles is from 10 nanometers to approximately 500 nanometers. It should be noted that carbon black looks very similar to activated carbon, but it is chemically very different and has different uses. In addition to high amounts of carbon in the composition of carbon black, other elements such as nitrogen, hydrogen and oxygen are also present in it; For this reason, it has different characteristics. It may be interesting to know that soot is one of the oldest products produced by mankind; The history of using carbon black goes back centuries when the Chinese and Indians used this substance as a pigment in ink, and in the 16th century, it became more important and a special place due to the development of the printing industry. Currently, more than 8 million tons of soot or carbon black are produced annually. Soot or black carbon is known by different names and each of them is produced by a traditional method:

Black Ivory: Made traditionally by ivory or bone
Black grapes: made traditionally from dried grapes and stems
Lamp black: Made traditionally by collecting soot from oil lamps

We Use Carbon Black In Variety of Essential Items:

Tires: Carbon black is used to improve the processing, strength and durability important to tire manufacturing and tire performance (most notably safety), increasing tire life and fuel economy.

Plastics: Carbon black provides color, UV protection and conductivity – power cable shielding or electrostatic dissipation – to plastics

Food Contact Grades: Specific carbon black grades comply with stringent purity requirements for many regulated industrial or consumer plastic applications.

Batteries: Carbon black improves electrochemical conductivity and charging characteristics in lead-acid, modern stop-start, and hybrid batteries – improving overall battery efficiency.

High Performance Coatings: Carbon black provides jetness for coatings, degradation protection from UV radiation and conductivity for coatings.

Rubber Goods: Hoses, belts, gaskets – carbon black is used to enhanced mechanical properties, anti-vibration and conductivity of rubber goods.

Pipe: Carbon black serves to protect pipes from mechanical degradation caused by harmful UV radiation.

APPLICATIONS OF CARBON BLACK

Considering the properties and characteristics of Soot, there are a lot of applications in which Soot is employed extensively. Soot is mainly used in rubber production industries and non-rubber applications including coatings, inks, plastics, etc. It could be claimed that nearly 90% of Soot application is in rubber production with two main classes namely tires and mechanical rubbers such as hoses at automotive belts. Carbon blacks reinforcing properties improves the performance and lifespan of the rubber material. Its application in rubber is typically divided into and N100 to N900 series blacks where N denotes the nitrogen surface area. The impact of CB properties on the performance of rubber is as follows. The smaller the particle size, the higher the tensile strength and abrasion resistance as well as the reduced rebound and dispersibility. As the porosity picks up, the tear strength and conductivity increase with the consecutive decrease in rebound. As the surface activity increases the abrasion resistance increases along with an increase in the rebound and modulus.

Almost 7% of CB is in non-rubber applications among which the widest applications are in plastics, coatings and inks. The other applications are in manufacturing batteries, toners and sealants. CB in these applications is employed due to properties like gloss, tint, blackness, ultraviolet light, protection and conductivity. Similar to rubber, the impact of physical properties of carbon blacks on non-rubber are as follows: As the particle size increases, the blackness, viscosity and ultraviolet protection ability, conductive and tinting strength increase. However, this results in a decreased dispersibility of carbon blacks. The higher porosity results in an increase in viscosity and vehicle demand. This allows reduced loadings in applications where conductivity is crucial. The increase in surface activity improves micro-dispersion and stability and reduces viscosity of liquid systems.

CHARACTERISTICS OF BLACK SOOT

Black carbon or soot, like other types of chemicals, has unique characteristics and has various uses. Among the most important features of this material, the following can be mentioned:

The ability to absorb harmful ultraviolet light and convert it into heat
Having different types such as acetylene black, channel black, furnace black, lamp black, thermal black and pigment black
High surface-to-volume ratio: although this ratio is lower compared to activated carbon.
Being spherical: Of course, compared to graphite, it has less crystalline order and if it is heated for a long time at a temperature of 3000 degrees, it turns into graphite.

N-220: This grade is used in passenger tires with its reinforcing properties and high tear resistance and good process capability.

N-234:This grade with high abrasion resistance and high structure is used in elastomers and SBR / SR alloys.

N-330:Due to the medium and upward reinforcement properties of this grade and its optimal process capability and moldability, it is used in rubber sides, carcass components, coated compounds, and tire belts.

N-339:The reinforcement property and high hardness coefficient of this grade, along with its excellent process capability, make it possible to use it to make the middle layer of the tire.

N-375:Due to its reinforcing properties, high hardness coefficient, and excellent process capability, this soot can be used to make the middle layers of the tire.

N-550:Reinforcing properties and high hardness coefficient and the ability to form smooth surfaces with this grade has led to the widespread use of this grade in the manufacture of molds and internal structures of tires, wall components, pipes, and hoses.

N-660:One of the properties of this soot grade is medium reinforcement, and this grade is used to make the inner layers and outer wall of the tire, cable cover, sealing rings, and so on.

N-772:The properties of this soot grade are low reinforcement, a small building with high jumping power, and it is used in impeller belts, aircraft tires, used in pressure-sensitive parts.

HARD/SOFT CARBON BLACK

Two types of carbon black are commonly used by the rubber industry for reinforcing rubber.
The first is the so-called hard carbon black which imparts high wear resistance to rubber into which it has been compounded.
Hard carbon black is generally used to make vehicular tire treads. Another type of CB, which imparts a different set of properties to rubber, is a so-called “soft” CB.
Soft carbon blacks are generally used to reinforce rubber where a great deal of flexing is expected to be encountered, such as in tire carcasses.
Hard carbons are commonly classified as being in the N100, N200, or N300 series. Some carbon blacks are commonly classified as being in the N500, N600, and N700 series.
The processes for making soft and hard carbon blacks differ considerably.
A soft CB as compared to a hard CB is one which, when mixed in a conventional rubber compound and the compound vulcanized, yields a product which is soft, more resilient, more rubbery, and yet tough; whereas a hard CB in the same compound imparts stiffer, tougher characteristics with low resilience.
The “channel” black process, though it produces a hard black, is a very wasteful process as only 3.5 percent of the Soot content of the gas (the feedstock to the channel black process is natural gas) is converted into CB. So called “furnace” black uses liquid hydrocarbons and converts a’ much higher content of the carbon to than does the channel process.
The characteristics of the carbon black produced by the “furnace” type process depend to a large extent, upon the type of liquid hydrocarbon material used as a charge to the process.
It has been found that low API gravity cracked gas oil having a high aromatic content is very desirable as a feedstock for the “furnace” black process.
