- Q: Zirconium corundum 25 content and 40 content, how to distinguish in appearance?
- The fused zirconia corundum brick is mainly made of fused zirconia and corundum. ZrO2-Al2O3-SiO2 three element system fused brick, containing Al2O3:40% to 50%, ZrO2:30% to 50%, SiO2:10% to 17%.From the point of view of data analysis, there is no radioactive substance in it, and it will not cause harm to the human body.
- Q: What is the price of concrete self insulation bricks?
- If you really want to buy thermal insulation brick, do not simply look at the price, but also to consider the quality of the product. (a piece of brick in the market basically in 6 yuan, if there is a floating price if it is because of the size of the insulation brick or distance, but floating slightly.)
- Q: What equipment is used for producing diamond blanks? How much is the investment?
- Plus all the cables fifty thousand. Steel 10000 yuan. Corundum bricks; insulating bricks; clay bricks, these three require more than ten thousand. The electrode is about one hundred thousand. It's just an investment in an electric furnace. Together with the rear section processing and raw materials need hundreds of thousands of.
- Q: Which is good, glazed brick and whole cast glazed brick?
- Vitreous tile is all ceramic tile, the material is hard, strong wear resistance, smooth finish is very good, in general, looks very bright. Microcrystalline brick, corundum brick Market said, they really mean bohuazhuan. Because of its low water absorption and high strength and hardness, glazed tile has been widely used. Many hotels, shopping malls and office space are widely used glass tile.
- Q: Wave tile and throwing glaze, tile which good?
- Vitreous tile is all ceramic tile, the material is hard, strong wear resistance, smooth finish is very good, in general, looks very bright. Microcrystalline brick, corundum brick Market said, they really mean bohuazhuan. Because of its low water absorption and high strength and hardness, glazed tile has been widely used. Many hotels, shopping malls and office space are widely used glass tile.
- Q: Can the PE sintering plate dust collector be suitable for dust removal in the coking plant?
- Do not know where the coking plant do dust treatment, processing conditions are different, the dust collector is not the same
- Q: What is the hardness of corundum refractory bricks?
- Al2O3 containing more than 90% greater than the refractory brick called corundum refractory brick, also known as pure alumina refractory products. Corundum has a high hardness (9 Mohs hardness) and a high melting point. These are closely related to the firmness of the Al - 0 bond in the structure. Therefore, a-Al2O3 is the main phase of making high temperature refractory bricks and high temperature electrical insulating materials.
- Q: Is liquid phosphoric acid two aluminum hydrogen flammable?
- Two aluminum liquid hydrogen phosphate using spray paint, cement, refractory castable and binder for foundry industry, mainly used in refractory industry corundum, chromium corundum nozzle coal water slurry gasifier with chromium aluminum zirconium corundum brick production.
- Q: Ask for help about the phase of refractory material
- Secondary crystalline phase. The second phase and second phase or second phase, and the main crystal phase and is in high temperature liquid phase coexistence in refractory material, the number and influence on high temperature properties of materials is the main crystal phase is small second phases. As to the main crystalline phase of periclase magnesia chrome brick, magnesia brick, magnesia brick and magnesia calcium brick respectively containing Cr spinel, spinel, forsterite and calcium silicate two are secondary phase. There are structure of refractory refractory material in the crystal phase, especially the direct combination of high melting point and so on, the resistance to high temperature also tend to benefit. Compared with the ordinary brick, the second phase of the refractory products, make the products refractoriness under load are improved. Many according to mineral composition of refractory material named, such as mullite corundum brick, corundum mullite brick, is its main crystal phase and the second phase composite named. The former is mainly crystal phase, the latter is sub crystalline phase.
- Q: What problems should we pay attention to in the use of fused zirconia corundum brick (fused zirconia corundum brick) in glass furnace?
- The expansion curves of fused cast AZS brick at 1000 DEG C near a crystal anomaly, its internal changes of ZrO2 crystal are reversible, with large volume change, therefore, products containing ZrO2, should not be used in the temperature of 1000 DEG C, often have sharp fluctuations in the position. When baking the kiln, the temperature can not be too large at 900~1150 degrees centigrade. Generally, the temperature can not exceed 15 degrees /h, and the temperature should be raised steadily. Some parts to prevent the cold, with other brick protection, to prevent explosion.
