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.

Rubber Carbon Black Bricks

Q: Because of the recent relates to this industry, by way of learning to name for all raw materials, I hope knowledgeable friends exhibitions, thank you.: Acidic materialMainly siliceous materials, such as quartz, tridymite and cristobalite, chalcedony, flint, opal, white quartzite, silica sand, diatomaceous earth, silicon oxide contained in these siliceous materials (SiO2) at least 90%, pure raw materials are silicon oxide as high as 99% or more. Siliceous materials at high temperature is the acidic nature of chemical dynamics, when the presence of metal oxide, or when in contact with the chemical reaction, and combined with a fusible silicate. Therefore, if there is a small amount of metal oxide in siliceous material, it will seriously affect its thermal resistance.

Q: What is the effect of the content of silicon nitride in silicon nitride bonded silicon carbide brick on the use of electrobath? Thank you: Small fluctuations in the chemical composition do not have a significant effect on use. The key is the operation of the electrolyzer in production to determine whether the side wall will be damaged.

Q: Semisilica brick interpretation: High temperature volume stability. Volume change is small.

Q: What is acid refractory?: Acid refractory material usually refers to refractories with SiO2 content greater than 93%. Its main characteristic is that it can resist acid slag corrosion at high temperature, but it is easy to react with alkaline slag.

Q: How much is the highest melting point of silicon?: Mainly used for partition, carbonization chamber of coke oven and combustion chamber open hearth furnace regenerator and a sediment chamber, soaking furnace, glass melting furnace refractories and ceramic kiln, kiln vault and other load-bearing parts. Also used for high temperature bearing part of hot blast stove and acid open hearth furnace

Q: Glass kiln brick for physical and chemical indicators?: Glass kiln with high quality silica brick products according to the standard JC/T615-1996, the single brick is divided into 3 grades: XBG-96, ZBG-96, DBG-96.

Q: How to judge the quality of brick, clay brick, high alumina brick furnace from the appearance?: Mainly depends on the color and density of brick. Another black clay brick and brick with iron oxide formation and how much the size of bricks

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: Brick belongs to refractory materials, with strong resistance to acid slag or acid solution erosion ability, high load softening temperature are excellent properties of silica brick, usually 1640-1680 C.

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
