Q: What is the price of the latest thermal insulation material?: There are many kinds of insulation materials, and the price will fluctuate with the market. Small quantities of inquiry or procurement, then go directly to the local thermal insulation market, a wide variety of prices are basically the market price.

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: Density of high alumina bricks: High alumina brick by aluminum content is divided into four grades, three grade high alumina bricks content of not less than fifty-five percent, two grade high alumina bricks content of not less than 65, a high aluminum brick content of not less than 75, super high aluminium brick content above 85. As for the high aluminum brick shape, in addition to the standard high alumina brick, high alumina brick and general type, also called special high alumina brick, if the shape is very irregular it is usually called the specific type of high alumina brick, in short, to customized according to the specific use of kiln.

Q: How are the high alumina bricks fired?: Generally, the high alumina bauxite is added with a small amount of clay. After being ground, the gas is injected and shaped in the form of slurry by the way of gas attack or foam, and it is burnt at 1300~1500 DEG C. Sometimes industrial alumina can be used to replace part of bauxite clinker. Used for lining and thermal insulation of masonry kilns, as well as for areas where there is no high temperature, high melting material erosion and erosion effects. When touching the flame directly, the touch temperature shall not be higher than 1350 degrees.

Q: What is the difference between T3 refractory bricks and high alumina refractory bricks?: The T3 in T3 refractory bricks refers to the model indicating that the refractory brick model is T-3, and that the corresponding T-3 model is 230*114*65 (mm)

Q: Which is faster for heat transfer between corundum bricks and high alumina bricks?: 75 high aluminum and 43 clay bricks, 75 single weight 4.5kg or more. 43 3.65kg or so, the use of temperature 75, high aluminum in about 1520, 43 of brick 1430 or so, the color of 75 pan white, 43 of the Loess color. In short, the difference is great.

Q: Can high alumina brick resist carburizing?: It is heavy brick mullite brick, brick to do the heavy weight to more than 2.4 manufacturers can achieve a few feeling

Q: What does refractory consist of?: According to the chemical characteristics of refractory raw materials can be divided into acidic refractory materials, such as silica, zircon etc.; neutral refractory raw material, such as corundum, bauxite, mullite (acidic) (acidic), Ge (alkaline) iron and graphite; alkaline refractory materials, such as magnesite, dolomite, magnesium sand calcium sand.

Q: What kind of material is the general metal case?: Ordinary computer chassis and the material itself does not produce high-energy radiation, only in the space environment of the computer is the external defense requirements, and in the space structure, the use of lead as protective materials, unbearable weight.

Q: What are the categories of bricks?: Clay brick materials, cheap, durable, and fire prevention, heat insulation, sound insulation, moisture absorption and other advantages, is widely used in civil engineering. Waste brick can also be used as aggregate of concrete. In order to improve the shortcomings of ordinary clay bricks, such as small, self important and waste of soil, they are developing in the direction of light weight, high strength, hollow and big blocks.
