Q:I wanna ask about the thermal insulation material fire resistant level?: The inorganic glass wool, rock wool and foam glass. Organic: The best is the phenolic foam, phenolic foam composite cement layer is level A.

Q:Who knows about the fire endurance of sintered shaly hollow bricks?: 1. after roasting at high temperature of more than 1200 degrees, shale burned bricks in construction works can be free from expanding with heat and contracting with cold. 2. masonry walls can be plastered with no needs of any anti-cracking, reinforcement measures, and walls will not bulge and crack, which can reduce the construction cost, as well as are preferred building materials of frame structural engineering. 3.They have good sound insulation and thermal insulation performances, are one of the green building materials that the state currently promotes. 4. They have high intensity. The average compressive strength of them is up to 15.8, which matches with M7.5 cement mortar that has advantages of low water absorption, and good anti efflorescence performance.

Q:which kind of refractory is commonly used in the industry: Like silicon, magnesium calcium and metallurgy refractories, glass, silicon, etc., knowing the basic materials, and the businesses are not the same. I suggest that you can buy the refractory book to read.. Others include zircon, shapeless refractory material and so many other cement, such as magnesia, high alumina,ect.. Iron making is using the acidity material, continuous casting is using the clay, nonferrous metals and other types of more complex hot-press charcoal; steel making is using the alkaline, magnesium chrome, magnesium carbon, and clay,etc..

Q:What's the requirements of fire-fighting criteria of heat insulating material?: It shouldn't be under than B2 level. Roofing insulation fire rating requirements: the ministry of public security, housing and urban-rural development department issued about printing and distributing the civil building external thermal insulation system and the interim provisions on the exterior wall decorative fireproof prescribed in the notice: roof grassroots adopted duration of fire resistance is the non-combustible component that shouldn't less than 1.00 h's. Its roof insulation materials should not be below B2; Otherwise, the combustion performance of insulating material should not be below the B1 level. The junction of the roof and wall, the insulation layer around the opening part of roof should use the grade A thermal insulation material to set level fire-fighting belt that width is not less than 500 mm.

Q:Who knows how many poured refactory material are there?: Casting refractory material, refractory material used often are AZS brick, corundum brick, direct bonding magnesia chrome brick, silicon carbide, silicon nitride bonded silicon carbide brick, nitrides, silicides, sulfide, boride, carbide and other non oxide refractory materials; calcium oxide, chromium oxide, aluminum oxide, magnesium oxide, beryllium oxide and other refractory materials.

Q:The manufacturing technique of refractory material: Melt blowing method is to melt the ingredients first, In addition, hiphotos, organic impurities, to be mixed, add sulfite pulp waste liquid into magnesia billet , ensure the accuracy of the product dimension. The products are mainly used for light refractory. then dry and fire with sintering to reduce the firing shrinkage of products, making it disperse into fiber or hollow sphere. The porpose of pre sintering raw material is to Sintering method is pre-sintering part of the raw material into clinker. such as adding binding clay into aluminum silicate blank

Q:can slag tailings be used to be the base materials of refractory materials ?: the rest of it can be used as refractory additives. the scale currently used clay bricks to make high-temperature liquid. It is easy to produce large amounts of liquid because of the high iron content, instead of its refractoriness. But it can be used as refractory minaralizer.

Q:How many hours of the fire endurance time of the rock wool laminboard?: Hello! Manager! The fire endurance of the rock wool laminboard is generally two hours. If you need the fire?rating of the rock wool laminboard, then I recommend you to buy it from the standard factory ! The one with higher fire rating can use polyurethane edge banding rock wool board and handmade glass magnesium rock wool laminboard.

Q:What dose the fireproof and thermal insulation material include?: Currently the non-combustible insulation materials for external insulation system mainly are foam insulation board, composite cement foam insulation board, aerated concrete panels, rock wool board (strip), and inorganic insulation materials. 1. foam insulation board refers to foam ceramic insulation panels whose raw material is inorganic ceramic which is calcinated at high temperature with abbreviation of ceramic insulation board 2.Composite cement foam insulation board is a hydrophobic lightweight closed-cell insulation board whose main materials are cement, fly Ash, and silica fume which has been foamed, cured and cut. 3. aerated concrete panel is a lightweight concrete panel which has been autoclaved with lightweight materials, siliceous material and gas former as its raw materials. 4. rock wool panel, with natural igneous rock wool as its main raw material, is a cotton which is melted in high temperature by centrifugation and is pasted by thermosetting resin.
