Q:Refractory factory grinding brick dust harmful to the body?: The effect is very large and belongs to lung disease.

Q:Urgent question: could you tell me that the export of refractory materials to Vietnam is to be packed in wooden cases and smoked?: Why is the apple screen so small?

Q:What are included in roof thermal insulation fireproofing material?: Aluminium foil, bubble, aluminium foil/air bubbles/fireproofing aluminium foil thermal insulation material, fireproofing bubble thermal insulation material, fire?retardant thermal insulation material, thermal insulation construction materials, aluminum foil insulation material.

Q:Does anyone know the difference between refractory and thermal insulation material?: Refractory refers to inorganic nonmetallic material, whose refractorinessis not less than 1,580℃, but refractory is not necessarily insulated material. Inorganic thermal insulation material also belongs to refractory as long as its refractoriness is higher than 1580℃.

Q:What is the fireproofing requirements of external wall thermal insulation materials?: According to the "building external wall insulation fire barrier zone technical regulations" to be published: it is not less than the level B2. But before the procedure was published, it should be strictly implemented the document, level A is the best, I hope to help you, hope to adopt

Q:What kind of fireproof material is used for steel structure?: Brushing or spraying the coating on the surface of steel structure to prevent burning and insulate heat. It also prevents undermining the rolled steel from rapid temperature elevation and avoid collapse of building for lose of supporting capacities. Agglutination material are classified as fireproof coatings for steel structures which is solvent based and Water-based steel structure fire retardant coatings. Fireproof coatings for steel structures which is solvent based are subdivided into fireproof coatings for steel structures which is solvent based with low benzene content and fireproof coatings for steel structures which is solvent based with high benzene content (TVOC≤600g / L, benzene ≤5g / kg). It can be divided by thickness. ultra-thin (CB) fireproof coatings (coating thickness ≤3mm), thin (B) fireproof coatings (3mm & amp; lt; coating thickness ≤7mm) and thick (H) steel structure fire retardant coating (7 mm & amp; lt; coating thickness ≤45㎜).

Q:who knows the requirements of refractory for forge furnace?: Requirements are as follows: 1, it should have enough refractoriness and softening point under a fixed load. Because under the effect of electric arc, inner surface temperature in different parts of furnace lining can reach 1500 ~ 1800 ℃. 2, it should have strong slag resistance. Because slag and smoke at high temperature penetrate through furnace lining to its internal lining, causing the melting of refractory, organization stratification, and even peeling?off. 3, it should have good thermal shock resistance. Because in the process of steelmaking, openning the oven door and lifting the furnace lid will make temperature of refractories in the furnace lining change rapidly, it might happen peeling?off and cracking, causing the premature failure of furnace lining. 4, it should have sufficient strength, because the furnace lining will be shocked when being loaded, vibrated when being tilted, scoured by metals,molten slag and air flow when boiling. 5, smaller thermal conductivity, lower electrical conductivity. Commonly used refractories for electric furnace include magnesia bricks, dolomite brick, high alumina refractory brick, siliceous refractory brick and magnesite ramming material,etc. owing to the different work environment of each part of the furnace,refractory used by each part is also different.

Q:How long is the duration of fire resistance that fireproof window of level B can endure?: Level B refers to the fire resistance rating and different hours in fireproofing of the fireproof window. Fireproof window of level A can endure fire for 1.5 hours while level B, 1.2 hours

Q:What is the use of refractory?: Some is insulated for personnel safety, some is to save heat loss and conserve energy, and some is used as lining of kilns. Because of its light weight, I recommand it to you and I am engeged in ceramic fiber, just an advertisement.

Q:how to classify the fireproofing material levels A1 A2 B1?: their classification is shown specifically in Fireproof? Specification of Building Interior Decoration?Design GB 50222-95 appendix A, flammability,inflammability materials, flame retardency, noninflammability: combustion performance of A, B3, B2, B1 materials are divided into
