Q:What are the requirements when producing fireproof materials by kaolin?: Kaolin refractories in fact play a role in two aspects, one is to improve the refractoriness, the second is to improve plasticity of the the refractory . Aluminum content the higher the better, of course, but kaolin is not the only material to improve the content of aluminum, using materials that contain higher content of aluminum such as the bauxite chamotte. So the content of kaolin aluminum does not have to be too high. over 38% is fine. viscosity is important and strong viscidityis better without having to add bentonite. Refractoriness above 1400 degrees is enough.

Q:In entering fire door, which material does well?: Entering door has two kinds: security doors, fire security door. The pure fire door does not have anti-theft function. In the relevant technical standards of fire doors : when in the fire, it can make residents in a few seconds or 1 minutes forget to open the door... The material of fire door, fire door has steel fire door and wooden fire door. There is no doubt that wooden fire door can't be used as entering door. In the steel fire door, two layers of steel plate in the clip is flame retardant material.

Q:What are the types of advanced refractory?: it can be divided into two categories of general and special refractories ordinary refractories by chemical properties into acidic, neutral and alkaline. Special refractory composition divided by high temperature oxide, refractory compounds and high-temperature composite materials Furthermore, according to refractoriness can be divided into ordinary refractory products (1580 ~ 1770 ℃), advanced refractory products (1770 ~ 2000 ℃) and grade refractory products (2000 ℃ above). the article can be divided into blocks (standard bricks, shaped bricks, etc. ), special shape (crucible, sagger, pipe, etc.), fibrous (aluminosilicate, zirconia and boron quality, etc.) and a random shape (refractory clay, pouring materials and ramming mixes, etc.) according to the sintering process it can be divided into sintered products, cast products, melt blown products.

Q:For refractory, why is it necessary to store the first mixing materials for some time under proper moisture and temperature?: It is mainly to remove gas form chemical reactions in the pug, give full play to plasticity and binding properties of combined, and store unburned?brick whose cememting agent is phosphoric?acid or aluminium?phosphate for some time under proper moisture and temperature. For example, to avoid the formed bricks in the initial stage of drying and firing form cracking due to hydration of calcium oxide. Mixing materials is to store the first mixing materials for some time under proper moisture and temperature in order to improve the evenness and moldability of pud, such as making the distribution of combined clay and water more even. The length of storing chiefly depends on the process requirements and the characteristics of blanks. For the producing pug of high temperature kiln furnitures, the storing time is longer. The function of storing mxing materials varies with different natures of blanks. For honeycomb ceramics, it is to fully digest calcium oxide in blanks. For storing magnesia brick blanks containing much calcium oxide, it should be stored for some time in proper humidity and temperature.

Q:I want to consult the fire resistant level standards of external wall thermal insulation materials.: 1, The building with the height larger than or equal to 100m, should have the A-level combustion performance. 2, The thermal insulation material of the building, with a height larger than or equal 60m and less than 100m, should not be less than the level B2 combustion performance. When using the level B2 insulation material, each level should set horizonal fire barrier zone. 3, The thermal insulation material of the building, with a height larger than or equal to 24m and less than 100m, should not be less than the level B2 combustion performance. When using the level B2 insulation material, each two levels should set horizonal fire barrier zone. 4, The thermal insulation material of the building, with a height less than 24m, should not be less than the level B2 combustion performance. When using the level B2 insulation material, each three levels should set horizonal fire barrier zone. I hope my answer will help you. Thank you!

Q:What substitutes are available for high-end refractories in addition to zircon sand?: Natural ore, synthetic raw materials such as industrial synthetic mullite, etc..

Q:what kind of fireproof materials is used for high rise buildings?: Recommended thickness of 1mm or more # 304 stainless steel, refractory, corrosion-resistant, easy to clean. closed balcony of high rise buildings use thickened manganese, aluminum profiles. You can also use plastic steel window, solid wooden windows. Mg-Mn alloys have excellent weldability and corrosion resistance, unstressed corrosion tendency. Mechanical properties are not good enough, the ultimate strength of 210 ~ 280MPa.

Q:Can refractory be used as sealing element?: The sealing element can resist the high temperature of 1200 degree.

Q:Is fireclay corrosive?: No. All of the refractory materials have stable chemical properties and their usability can be guaranteed under high temperatures.

Q:I wanna ask you, which level is b1 fireproof and thermal inuslation matertial ??: which level is b1 fireproof and thermal inuslation matertial: I soppose you mean rubber and plastic! Only rubber and plastic has b1b2 level. Level b1 is the fireproofing level b1, because the rubber and plastic does not belong to the fireproofing material. It only has fire?retardant. The wholesale of all kinds of thermal insulation material and construction needs to look at the name.
