- Q: Application characteristics of high alumina brick
- Refractoriness. High alumina brick products are advanced varieties of aluminium silicate refractory products, and their refractoriness increases with the increase of Al2O3 content, generally not less than 1750 - 1790 DEG C. If the content of Al2O3 is more than 95% of corundum brick, the refractoriness can be as high as 1900-2000 degrees.
- Q: What are the specific raw materials for plastic pallets?
- With excellent mechanical properties, its strength and elasticity are higher than HDPE, and it has good flexural fatigue resistance. It has good heat resistance and good chemical stability. Besides being concentrated by concentrated sulfuric acid and concentrated nitric acid, it is relatively stable to other chemical reagents. The high frequency insulation performance of polypropylene is excellent because of its almost no water absorption, so the insulation performance is not affected by temperature.
- Q: What is the standard classification of high alumina bricks and high alumina bricks?
- High alumina brick is one of refractory materials. The main component of this kind of refractory brick is AL2O3. High alumina brick refractory clay brick and brick than refractoriness to high. It belongs to high refractory. High alumina brick Al2O3 more, close to the neutral refractory material, can resist acid slag and alkaline slag erosion, because it contains SiO2, so the ability of alkaline slag resistance than acid resistant slag ability is weaker.According to the number of AL2O3 content is divided into, 55,65, 75,80 and so on several grades.
- Q: What are the common thermal insulation materials for thermal conductivity?
- Aerogels are known to be the lightest solid materials in the world. It is made of nanometer silica aerogel as main material and is compounded by special process. The utility model has the advantages of high temperature resistance, low thermal conductivity, small density, high strength, green environment protection, waterproof and non inflammable performance. At the same time, with excellent sound insulation and shock absorption performance, it is now widely used in metallurgy, chemical, national defense, aerospace and other fields, is an indispensable high-performance insulation materials.
- Q: What's the price of high alumina refractory bricks?
- The price of high alumina refractory bricks varies greatly according to the content of AL2O3.
- Q: What is the density of a super high alumina brick and what is the price?
- Super high alumina brick, alumina content of 80% bricks, bulk density of 2.7g/cm3 or more, the factory price of about 1900 yuan
- Q: What are the specifications for bricks?
- Thecompressive node as a new type of building energy-saving wall materials, which can be used for masonry walls, but also has good thermal properties, in line with the construction of the building module, reduce the loss in the process of construction, improve work efficiency; the hole rate reached more than 35%, can reduce the weight of the wall, save the foundation engineering cost. Compared with common sintered porous brick, it has the characteristics of heat preservation, heat insulation, light weight, high strength and high construction efficiency. The product is made of shale as raw material. It is produced by high vacuum extrusion molding machine and one yard firing process
- Q: What are ordinary bricks, refractory bricks, hollow bricks?
- Referred to as refractory brick. Refractory wood made from refractory clay or other refractory material
- Q: How high can aluminum bricks expand at 80O degrees of heat?
- The expansion of high alumina brick is not only related to temperature, but also related to its material composition. The refractory temperature of high alumina brick is above 1770 centigrade. The temperature of 800 DEG C has little influence on the expansion of high alumina brick.
- Q: How can the refractory brick blast furnace be pulverized and pulverized enough not to be taken away by the wind?
- Top burning type hot blast stoveIt means that the burner is installed on the top of the hot blast furnace of the iron making equipment, and it does not need a special combustion chamber in the vault space. It is also called a non combustion chamber type hot blast stove.
