Rubber carbon black bricks
Product name:carbon black
Molecularformula: C
CAS No.:1333-86-4
EINECS No.: 215-609-9
Usage: Maily used in various rubber products such as tyres, rubber overshoes, cable, seal ring, tape etc. Also can be used in relevant industries such as plastic manufacutre.
It is mainly used for rubber intensifier and packing, its consumption is about half of rubber rubber consumption of carbon black with carbon black 94% of the total, with approximately 60% for tyre manufacture. In addition, also used for printing ink, paint and plastic colorants and plastic products BingBiJi of ultraviolet light, as well as important fertilizerFor many other products, such as electrode, dry, resistors, explosives, cosmetics, and polishing compound.
Grade:N220/N330/N550/N660 etc.
1) N220
Wear and the anti-cracking N110 compared with high, set out low stress, dispersivity is good.
2) N330
It with good abrasion resistance and medium hysteresis.
3) N550
It in soft carbon black varieties has the best reinforcing performance, excellent extruding performance, low resilient rate.
4) N660
It compared with N550, reinforcing the gender is low, the structure is lower, higher inflation, mouth filling quantity is bigger.

- Q:Can not use it two brick
- Acidic silica brick refractory material, has good ability in acid slag erosion
- Q:Why is the highest brick coke oven temperature measuring point temperature not exceeding 1450
- That is because the brick load softening point the maximum temperature is 1450 degrees.
- Q:How much is the highest melting point of silicon?
- Acidic silica brick refractories, softening temperature is as high as 1640 to 1670 DEG C, in the long-term use volume is relatively stable under high temperature. More than 94% silica content.
- Q:Physical solid waste disposal
- The amount of addition is related to the shape and weight of the brick. The bricks can be added to 20% weight less than 25kg; bricks above 25kg can be added to 30%; for the specific type of brick can be added 30%. into waste silica brick should pay attention to this problem
- Q:The specific content is what gb/t2608-2012 brick
- Quality assessment procedures, packaging, marking, transport, storage, and quality certificates. Suitable for siliceous refractory bricks.
- Q:Such purpose and scope please give me detailed points thank you because I am learning stage
- Acid refractory brick is mainly composed of tridymite and cristobalite and quartz and a small amount of residual glass phase.
- Q:Which material is good for furnace refractory?
- Kiln types of refractories is very extensive, selection of refractory materials according to the type of furnace furnace temperature and use of selected refractory material, refractory material is divided into custom products of refractory bricks and unshaped refractory castable series products. According to chemistry, it is divided into acidic, neutral and alkaline materials.
- Q:Why in the production of the brick to detect the volume density
- Fast density test, please consult an instrument.
- Q:The brick is mainly used in the place?
- Also used for high temperature bearing part of hot blast stove and acid open hearth furnace.
- Q:What role does silica play in refractories?
- The production of clay brick refractory clay raw material is natural, its main mineral is kaolinite (formula Al2O3 - 2SiO2 - 2H2O), clay brick containing SiO2 in 45% ~ 65%, belongs to the weak acid refractory materials, have a certain ability to resist acid slag, but easy to be alkaline slag erosion.
