Q:Who knows what is the standard of insulation material whose fire proof is level A?
Level A is distinct from B in coefficient of fire proofing. Level A is non combustible, while Level B is divided into B1( flame retardant), B2(combustible) and B3( inflammable). Currently in the market, level A materials are as follows: phenolic, rock wool, insulation mortar, ceramic foam, foam glass, and foamed concrete. The most advantageous of level A material at present is foamed concrete, also known as foamed cement. Xuzhou Lvchuang Construction company is working on this, you can search fro it on the internet, it has high cost performance.
Q:What are the use of fire-resistant material and admixture?
I am engaged in admixture and thus familiar. Welcome to exchange!
Q:What are the characteristics of phenolic resin as a refractory material?
Q:What are the applications of refractory?
Refractory materials are widely used in iron and steel smelting , glass, cement kilns, non-ferrous metal metallurgy, environmental protection, and chemical, etc. For example: For a car of 1.5 tons, do you you know how much refractory it use? The answer is: To produce top hat or other steel products, glass for vehicle windows, nonferrous metals kile aluminum and copper, plastic products of the body all needs refractory. A car of 1.5 tons needs to consume a total of 10Kg refractories.
Q:What refractories can withstand high temperature above 2100 degrees?
You can refer to advices from the first one coupled with the second one.
Q:I wanna ask about the thermal insulation material fire resistant level?
The inorganic have glass wool \ foam glass Bian \ the best of organic is phenolic foam \ phenolic foam composite cement layer is level A.
Q:What are the new types of refractories? What are the characteristics? Their applications and developments?
AZS refractories are often used brick, corundum brick, magnesia chrome brick, silicon carbide, silicon nitride bonded silicon carbide, nitrides, silicides, sulfide, boride, carbide and other non oxide refractory materials; calcium oxide, chromium oxide, alumina, Magnesium Oxide, beryllium and other refractory materials.Often used insulation refractories are diatomite products, asbestos products, insulation panels and so on.Unshaped refractory materials commonly used are fettling, refractory ramming material, refractory castable, refractory plastic material, refractory clay, refractory gunning, refractory cast material, fireproof coating, lightweight castable, mud etc..
Q:What refractories have good mechanical property resistance and heat expansion and cold contraction property?
Aluminium oxide ceramics. I would like to know that what kinds of refractory materials can combine together and what kind of masonry way can be used for these materials so as to achieve the perfect combination.
Q:What's the refractoriness and how to measure the refractoriness?
Bottom each side length is 8 mm and upper side length is 2 mm. Under a certain temperature-rising speed, when heating, refractory's resistance to high temperature from melting is called refractoriness. The properties of cross section into an equilateral triangle and height is 30 mm. When it bends down until the vertex and chassis contact temperature is the refractoriness of sample. It bends due to the influence of its weight. Make the will-measured material into standard pyrometric cone.
Q:Are refractory materials and fireproofing materials the same?
Both refractory materials and fireproofing materials belong to the industry of construction materials and each of them can also be treated as an specific industry.
