Q:What is the difference between fireclay bricks and high alumina refractory bricks?
High alumina brick is one of refractory materials. The main component of this kind of refractory brick is AL2O3.
Q:How to test the aluminium bricks of high alumina refractory bricks?
Forming high alumina brick will be tested on some professional equipment, it is suggested that you can go to the professional testing department to know about it!
Q:Refractory brick, high alumina brick, magnesia chrome brick or 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
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:What is the difference between T3 refractory bricks or high alumina refractory bricks?
The T3 in T3 refractory bricks refers to the model indicating that the refractory brick model is T-3, and that the corresponding T-3 model is 230*114*65 (mm)
Q:What's the difference between high alumina refractory bricks and high alumina refractory bricks?
The chemical pH value of high alumina refractory brick belongs to neutral and alkaline refractory brick, and clay refractory brick belongs to neutral and acid refractory brick.
Q:What's the weight of the refractory bricks?
According to shape and size can be divided into standard brick, ordinary brick, special brick, etc.. It can be used as high temperature building materials and structural materials for construction kilns and various thermal equipments, and can undergo various physical, chemical and mechanical changes at high temperature. For example, refractory clay brick, high alumina brick, brick, brick etc..
Q:What are the main components of high alumina bricks?
High alumina brick materials according to the main mineral phase can be divided into: aluminum silicate minerals, such as sillimanite, kyanite, andalusite, and synthetic mullite.
Q:High alumina brick 80 with which high aluminum cement?
In order to maintain a reasonable comprehensive lining, should adopt high quality aluminum refractory mud, such as Sichuan resistance card phosphate refractory mud, refractory clay, high alumina refractory mud PA-80 LN-75, if you use the card volume of Sichuan resistant refractory clay masonry, the effect is better.
Q:Corundum, high alumina and fireclay refractory difference is what
Corundum is unknown. The high alumina brick has higher aluminum content than the clay brick, and the temperature resistance is higher than 300 degrees. It is more durable and durable than the clay brick. The production process of high alumina brick is better than that of clay brick. For example, the weight of good clay brick is 3.7kg, and that of high alumina is 4.2kg. Good density. But the price of high aluminum is too high: ordinary clay brick (standard brick example) in 1.1--2.5 yuan / block, high aluminum to 4.5 yuan / block, or even more expensive. The extra high aluminum has reached 5000 tons. Say straight white point is: under the same conditions, clay brick for a period of one year, then the high aluminum for more than three years.
