- 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 are the specifications for bricks?
- In a proper ratio of lime sand brick and quartz sand, sand or fine sand, the ground, Kazumi Wa, semi dry pressing and autoclaved curing and. The fly ash brick is made of fly ash as main raw material and mixed with cement material such as coal gangue, stone powder or clay. It is made up of batching, molding, drying and roasting. It can make full use of industrial waste residue and save fuel.
- Q:Are there any differences between insulating bricks and refractory bricks?
- As the name suggests, the main role of insulating brick is used to preserve heat and reduce the loss of heat. Such as: Molai S; and the firebrick is mainly used to withstand flame burn. Bricks usually do not contact fire directly, while refractory bricks usually contact the flame directly.
- 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:The difference between ordinary and diatomite brick refractory brick
- Refractory brick belongs to a large class, according to different materials used are divided into: high alumina brick, dolomite brick, magnesia chrome brick, magnesia spinel brick, phosphate brick, carborundum brick, brick, mullite bricks etc..
- Q:Which thermal shock stability of clay brick and high alumina brick is good?
- High alumina brick is made of superfine alumina, fused corundum and fused mullite as main refractory materials.
- Q:Does the chimney have high acid resistance?
- The acid resistant bricks used for chimney are usually made of custom-made trapezoidal acid proof bricks, and the physical and chemical indexes of acid resistant bricks need to be confirmed according to the chimney's actual emission. At this point, you can consult our kerei refractories.
- Q:What are the common thermal insulation materials for thermal conductivity?
- The vacuum heat insulation plate is a kind of high efficiency thermal insulation board made of inorganic fiber core material and high resistance gas composite film. It is made of vacuum encapsulation technology and covered with special interface mortar.
- 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:What are the high temperature refractory mortars made of?
- Products used in metallurgy, building materials, machinery, chemical, power industry, industrial thermal furnace, for masonryBuilding clay brick, high alumina brick and corundum brick have the characteristics of full grey seam, good airtightness, high bonding strength, high temperature performance and suitable construction time
