- Q: What are the main components of high alumina bricks?
- Sweat is like water mineral alumina bauxite, aluminum ore, magnesite, waves of gibbsite. Anhydrous alumina raw material, such as corundum, alumina, fused corundum. High alumina brick Zhengzhou gold company specializing in the production of various specifications, you can directly ask their technical staff.
- Q: What is the difference between corundum and high alumina??
- The main component of high purity 99 corundum brick is corundum sand,90 corundum brick is mainly composed of corundum sand and a small amount of Suzhou soil, mullite.
- Q: What is the standard classification of high alumina bricks and high alumina bricks?
- High alumina brick is a kind of refractory material in refractory brick products. It is made of refractory clay or other refractory material. It belongs to the product of Si Al System
- Q: What materials are used for roof insulation?
- The other one is inorganic insulation materials, such as Portland, rare earth insulation, the thickness should be 5 cm or more, up to the high cost of auxiliary materials of construction, to reinforce, new inorganic insulation material, the material thickness, on the line of 2-3 cm, direct smear on the top of the house, without auxiliary material, than the price of wool, high aluminum silicate cotton.
- Q: How to reduce porosity of high alumina brick
- In order to reduce the porosity of high alumina brick, the corresponding measures should be taken from the selection of raw materials, batching, mixing, molding and firing.
- Q: How to distinguish the good or bad of the high aluminum brick?
- Weigh the weight of the next block. According to the weight standard, a high alumina brick is 3.9 kg in weight, two in high alumina brick, three in high aluminium brick and 4.5 kg in 4.2. The same grade, the same type of high alumina brick, if the weight of a single brick to this standard, but for high quality high alumina brick, otherwise, can not reach such a weight, it shows good quality. If there is a crack, a large piece of broken angle, four sides of inequality, it is for substandard products.
- Q: Refractory brick, high alumina brick, magnesia chrome brick, magnesia brick, clay brick, which type of high temperature refractory brick?
- High alumina brick clay brick up to 1700 degrees above 1500 degrees -1750 degrees of magnesia brick and magnesia chrome brick 1500-1650 degrees, I is the production of clay brick, brick my temperature at 1500-1700 degrees. Specific depends on what kiln, brick is only part of it
