Definition of carbon black:
Carbon black is a product obtained from the incomplete combustion of hydrocarbons, and is the earliest nano-scale material used by humans. The use of carbon black in my country has a long history and has made great contributions to the development of carbon black history in the world.
Classification of carbon black:
Carbon black can be divided into different types according to different classification rules, mainly can be divided into the following types
1. Classification according to production method
The production process of carbon black has experienced different developments. According to the production process, carbon black can be divided into furnace carbon black, channel carbon black, roller carbon black, contact carbon black, thermal cracking carbon black, spray carbon black
2. According to the different classification of raw materials
According to different raw materials for carbon black production, carbon black can be divided into oil furnace carbon black, gas furnace carbon black, acetylene carbon black
3. Classification according to usage
According to the use of carbon black, it can be divided into two categories: rubber carbon black and non-rubber carbon black, and rubber carbon black can be divided into hard carbon black and soft carbon black. The particle size of hard carbon black is 40nm Below, the particle size of the soft carbon black is 40 nm or more. Rubber carbon black has the following models: N330, N220, N550, N660, N770, etc. Non-rubber carbon black can be divided into conductive carbon black and pigment carbon black (pigment carbon black for sealants:
Automotive sealant, building sealant, ship sealant, container sealant, industrial sealant, waterproof sealant, hot melt adhesive, hollow glass sealant, pigment carbon black hollow glass butyl glue, Neutral anti-mildew silicone sealant, copper sealant, polyurethane sealant, neutral glass sealant, sealant strip, acid silicone sealant, butyl sealant. Pigment carbon black for colorants:
Black synthetic leather colorant, printing colorant, water-based colorant, papermaking colorant, apple bag paper, PVC colorant, PU colorant, oily colorant. Pigment carbon black for color masterbatch:
Pigment carbon black (for shoe material EVA foam), pigment carbon black for halogen-free cable material, (for plastic foam) pigment carbon black, pigment carbon black for blown film masterbatch, pigment carbon black for plastic masterbatch, pigment carbon For black PVC cable material, for pigment carbon black PVC granules, for pigment carbon black polyester masterbatch, for pigment carbon black high-gloss blue phase color masterbatch, for pigment carbon black chemical fiber color masterbatch, for pigment carbon black staple fiber color masterbatch, Pigment carbon black for calendering film, pigment carbon black PE cable material. Pigment carbon black for ink:
High pigment carbon black all-in-one ink, high pigment carbon black ink ink, pigment carbon black plastic woven bag ink, pigment carbon black plastic ink, pigment carbon black plastic composite ink, pigment carbon black plastic gravure ink, pigment Carbon black for gravure printing ink, pigment carbon black for screen printing ink. Pigment carbon black for paints:
Pigmented carbon black for motorcycle paint, pigmented carbon black for high temperature resistant paint, pigmented carbon black for epoxy floor paint, pigmented carbon black for anti-corrosion paint, pigmented carbon black for insulating paint, pigmented carbon black for heat-resistant paint, Pigment carbon black alkyd paint, pigment carbon black weather-resistant paint, etc. Pigment carbon black for special carbon black and building materials:
High pigment carbon black environmental protection carbon black for pencil lead, pigment carbon black for compound fertilizer, pigment carbon black for refractory material, pigment carbon black for concrete foam board, superfine pigment carbon black, water-soluble pigment carbon black, pigment carbon black for environmental protection Carbon black, pigment carbon black high temperature resistant carbon black, pigment carbon black insulating carbon black, high gloss blue phase pigment carbon black, pigment carbon black for artificial leather, pigment carbon black for cement pointing, pigment carbon black for cosmetic mascara. )
4. Carbon black is classified into super wear-resistant carbon black, super wear-resistant carbon black, super wear-resistant carbon black, fine particle furnace black, fast extrusion furnace black, general furnace black, high-definition furnace black, semi-complementing Strong Furnace Black, Fine Particle Thermal Black, Medium Particle Thermal Black, Easy-Mixable Tank Black, Mixable Tank Black.
How to choose to use carbon black
There are so many types of carbon black, and the uses of different carbon blacks will be different, and we can choose according to our needs.
For coloring: choose carbon black with high blackness and small particle size, but it must be ensured that the carbon black is properly and completely dispersed, otherwise it will run counter to the original requirements.
For color matching: choose carbon black with low blackness, large particle size and easy dispersion.
Anti-ultraviolet: mainly used in plastics and rubber and plastics, choose carbon black with medium particle size and slightly higher structure, and their anti-ultraviolet performance is the best.
No matter what purpose carbon black is used for, it is necessary to figure out what type and characteristics of carbon black are suitable, so as to make the best use of everything.
