Q: What are the high aluminum bricks made of?
The amount of refractory mud accounts for about 6% of the brick weight
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 price of the first grade high alumina brick?
Many factories in Xinmi have high alumina bricks, but they must choose a regular factory. Kuwait refractory level high aluminum brick price at around 1600, the quality of double stable supply
Q: Difference between low creep high alumina brick and ordinary high alumina brick
The emphasis is on the physical and chemical indexes of low creep and high alumina bricks. The physical and chemical indexes of the high alumina bricks are different, too. They are DRL-1550And LZ-75 perform GB GB/T2988-2012
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: Are there any differences between insulating bricks and refractory bricks?
The refractoriness of insulating bricks is generally below 1400 tons, while the refractoriness of refractory bricks is above 1400 degrees. 3. density insulation bricks are generally lightweight insulation materials, the density is generally in 0.8-1.0g/cm3, and the density of refractory bricks are basically above 2.0g/cm3.
Q: Use of high alumina refractory bricks?
Because of the high Al2O3 high aluminum products, low impurity content, the formation of fusible vitreous body less so than the clay brick high load softening temperature, but because mullite crystallization has not formed the network organization, so the load softening temperature is not high silica brick.
Q: What is the difference between metal compounds and metal solid solutions?
A series of intermetallic compounds occurring between transition metals in intermetallic compounds. The most important are L sigma sigma phase and ves phase, they are topologically close packed (TcP) phase, they consist of a small atomic radius of a dense layer, which is inlaid with a large atomic radius of atomic structure, this is a highly dense pile. In addition to atomic size factors, their formation is also influenced by the concentration of electrons.
Q: The difference between clay bricks and clay bricks
According to the hole rate: solid brick (no hole or hole rate less than 25% bricks), porous brick (hole rate is equal to or greater than 25%), the size of the hole is small and the number of bricks, usually used in load-bearing parts, higher strength level. Hollow brick (hole rate equal to or greater than 40%, large pore size and small amount of brick, commonly used in non load parts, low strength grade).Solid bricks and porous bricks are mostly used for load-bearing structural walls. Hollow bricks are mostly used in non load bearing structures.
Q: What are the categories of bricks?
Ordinary brick size of 240 mm * 115 mm * 53 mm, according to compressive strength (Newton / square millimeter, N / mm2) size is divided into MU30, MU25, MU20, MU15, MU10, MU7.5, these intensity levels.
