Q:Who knows the refractoriness of high temperature lightweight firebricks?
The disadvantage of light refractory bricks is its poor thermal insulating ability and the advantage is its endurable heat resistance property. The temperature range and main features of thermal insulation refractory are as follows. Diatomite brick
Q:What is the use of refractory?
It is used as a protective layer inside the high-temperature, high-corrosion, high-washing, easy to be wore equipment and as an insulation layer outside equipment.
Q:How to measure the influence of high-temperature performance of the products refractory in the formation of the liquid phase.
Seeing whether it can affect the usage of the refractory material, and seeing to reduce the impurity, what's the condition of temperature of the liquid phase. Practically, whether it has any difference if you can improve, load under load and creep and reduce the impurity content. In the refractories, producing liquid are the influence of impurities, high temperature resistant strength, compared the use of the refractory material temperature: testing compressive strength after burn. If there are any impact: knowing the main crystal phase of matrix composition and content, improving the content of the main crystalline phase can improve the high temperature performance of refractory materials.
Q:How is the fire endurance of the fireproof paint?
Fireproof endurance. fire resistance test of certain building components showed by standard time temperature curve from starting of fire to lose the supporting capabilities or its integrity or fireproof property. The fire proof endurance is 5hours.
Q:Which refractory is better for building 1500 degree kiln ?
The top and wall use alumina hollow ball brick. If it is cubic kiln, the kiln bottom should use heavy corundum brick. If it is continuous kiln, burning zone should use alumina hollow ball brick, burning zone seal and kiln car face brick. If it is pit furnace, curved seal should use heavy corundum brick, and furnace wall and top should use alumina hollow ball brick. That depends on what kind of kiln it is. Curved seal and kiln car should use heavy corundum brick. You can add me friends to have further talks.
Q:Do you know where I can buy refractories?
You can buy refractories in these places: 1. Addresses of refractory factory: No. 57, Qingshan District, Wuhan 2. Address of Qingshan refractory factory in Wuhan: Special NO.1 Xingli Road Hongshan District, Wuhan 3. Address of Xinghuo refractory factory in Hongshan district: No. 34 Qingshan District, Wuhan 4. Address of Henao refractory factory: No. 78 Jiangxia District, Wuhan
Q:Who knows about the fire endurance of sintered shaly hollow bricks?
1. after roasting at high temperature of more than 1200 degrees, shale burned bricks in construction works can be free from expanding with heat and contracting with cold. 2. masonry walls can be plastered with no needs of any anti-cracking, reinforcement measures, and walls will not bulge and crack, which can reduce the construction cost, as well as are preferred building materials of frame structural engineering. 3.They have good sound insulation and thermal insulation performances, are one of the green building materials that the state currently promotes. 4. They have high intensity. The average compressive strength of them is up to 15.8, which matches with M7.5 cement mortar that has advantages of low water absorption, and good anti efflorescence performance.
Q:What are the qualifications of refractory industry?
1 business license 2 tax registration certificate 3 organizing institution bar code 4 production permit
Q:Is aluminium oxide refractory material?
Calcination aluminium oxide is refractory material of fine performance made from pure aluminium oxide through high-temperature calcination. It can be made into coarse-grained material, fine-grained material, fine powder and micro powder, which can be made into pure jade burnt products. For example, corundum brick, lightweight corundum bricks. It can also be made into a variety of unburning products together with other materials, such as carbonaceous materials. For example, aluminum carbon and aluminium zirconium carbonaceous materials. As for the production of unshaped refractory material, there are more species. It can be corundum, rubing grain, corundum spinel and can also be added into other materials to improve specific performance. It isn't limited to high-alumina castable refractory and it can be castable refractory, ramming mass, impressionable plastic material, gunning mix and refractory mortar.
Q:What's the frequently used refractory material?
Refractory material is generally used in industrial departments like metallurgy, glass, cement, ceramics, machinery, hot working, petrochemical industry, power and national defense. Frequently used common refractory: silica brick, semi-silica brick, clay brick, high alumina brick, magnesia brick, etc. Frequently used special refractory: AZS brick, corundum brick, direct-bonded magnesia-chrome bricks, carborundum brick, calcium oxide, chromium hemitrioxide, alumina, magnesium oxide, etc. Frequently used fireclay insulating refractory: diatomite product, asbestos product, insulation board, etc. Frequently used unshaped refractory: ramming refractory, refractory castable, plastic refractory, refractory mortar, gun-mix refractory, refractory coating, lightweight refractory castables, etc.
