Q:High alumina brick 80 with which high aluminum cement?

In order to maintain a reasonable comprehensive lining, should adopt high quality aluminum refractory mud, such as Sichuan resistance card phosphate refractory mud, refractory clay, high alumina refractory mud PA-80 LN-75, if you use the card volume of Sichuan resistant refractory clay masonry, the effect is better.

Q:How does the physicochemical index change when the high alumina brick is used at high temperature?

When the high alumina brick is used at high temperature, the physical and chemical indexes and other constants will not change if the temperature is in the physical and chemical indexes and the softening temperature of the load.

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:What is the high temperature limit of refractory bricks and refractory soil?

Fire clay -- usually refers to folk point stove furnace set with a kind of soil, limit under atmospheric pressure of 1500 degrees fire clay soil 1, properties and uses: clay brick of weak acid refractory material, its thermal stability is good, suitable for hot blast furnace, boiler and flue, smoke chamber lining, etc..2, product specifications form: standard shape, general, special-shaped and special-shaped brick. Physical and chemical properties of fireclay bricks.

Q:How are the grades of high alumina bricks differentiated?

In China, the content of Al2O3 in high alumina brick is usually divided into three categories: I, etc. - Al2O3 content > 75%; II, etc. - Al2O3 content is 60 to 75%; III and so on - Al2O3 content is 48 ~ 60%.

Q:How to make refractory bricks and boiler wall adhesion more firm?

Suggest that you use fire brick to increase the length of brick or pull the amount of turn, and use high temperature mortar masonry

Q:The difference between clay bricks and clay bricks

Clay brick is a small building with artificial bulk. Also called sintered brick. Solid clay brick is one of the oldest building materials in the world. It is a building material that is loved by the people.

Q:What are the grades of high alumina bricks?

High alumina brick according to the aluminum content is generally divided into: super high alumina brick, a high aluminum brick, two high alumina brick, three high alumina brick

Q:What are the reasons for the spalling of refractory bricks in the production of lime kiln?

Therefore, the choice and masonry of refractory bricks are of vital importance. If there is a brick kiln kiln off block process of reproduction, is now because of the use of refractory brick kiln material mostly three grade high alumina bricks. The content of AL2O3 is about 55%, of which the content of Fe2O3 is about 2%, which is weak, and the alkali corrosion resistance is a little worse. In a containing three grade high alumina bricks in the composition of AL2O3, Si2O3, and other elements also contain K, Na trace, were the most, thus causing the system of the low melting point is very low, even at 1400 DEG C has been liquid phase, and generate CaAL12O19 limestone and calcium feldspar etc.. Form corrosion loss. Therefore, a long time will cause the loss of block. On the one hand, it may be caused by construction.

Q:Is glass wool inorganic thermal insulation material?

Yes, glass wool belongs to one kind of glass fiber. It is a kind of man-made inorganic fiber. Therefore, in the field of thermal insulation materials classified as inorganic insulation materials.
