Q: Why can aluminium hydroxide not be used to make refractory material?
Hope my answer is helpful to you. It decomposes and produces aluminium oxide and water after heating, chemical equation for the reaction is: 2Al(OH)3=△=Al2O3+3H2O. Aluminium hydroxide can't be directly used to make refractory material because aluminium hydroxide is not stable.
Q: Are the specification of fireclay bricks and ordinary clay brick the same?
Do you want to know whether the specifications of fireclay bricks and ordinary clay brick are the same?
Q: The classification of fire-resistant material
Refractory material cna be divided into common and special fire proofing material. Common fire proofing material can be sub-divided in to acid fire proofing material, neutral fire proofing material. and alkaline fire proofing material according to chemical properties. Special fire proofing material can be divided into high temperature oxide refractory, refractory compounds and high temperature composite materials according to the composition. In addition, it also can be divided into common refractory products (1580 ~ 1770 ℃), high-grade refractory products (1770 ~ 1770 ℃) and super refractory products (above 2000 ℃) according to the strength . According to the shape, it can be divided into block (standard brick, special-shaped brick, etc.), special shape (crucible, sagger, pipe, etc.), fibrous (aluminum silicate, zirconia and boron carbide, etc.) and irregular shape (refractory clay, refractory castable, ramming material and so on). According to sintering process, it can be divided into sintered product, fused cast product and melting jetting product.
Q: who knows the requirements of refractory for forge furnace?
Here is the requirements of refractory for forge furnace: according to the chemical properties,casting fireproof materials are divided into three major categories: acidic, neutral and alkaline refractory materials. alkaline and neutral refractory materials are commonly used, such as alkaline magnesia-carbon bricks and burned magnesite bricks, magnesite-chrome bricks, magnesium-calcium brick, neutral high alumina brick, corundum brick, clay brick, etc., shapelessness materials include: castable refractory, ramming?mass, gunning mix, coating, dry vibrating materials and so on! Hope my answer can help you.
Q: what's the fire endurance of fireproof?panel?
fire endurance of fireproof?panel generally is 3 hours. For example, 12 mm non-asbestos fiber reinforced calcium silicate board, fireproof?panel, two single 75 keel. through the monitoring of national fireproof construction materials quality supervision center, it's security and refractory time will reach over 3 hours. fireproof?panel, also called fire resistance board, scientific name is thermosetting resin impregnated paper laminated wood,english abbreviation HPL(Decorative High - pressure Laminate) is fire resistant building material for surface decoration and has rich surface colors,lines and special logistics performance, it's widely used in interior decoration, furniture, cabinets, laboratory table, external wall, etc.
Q: what's the varieties of thermal insulation material with A level fire?rating?
Inorganic thermal insulation material can do it, such as glass wool,rock wool,foam glass,etc. phenolic foam materials in organic foam material is special. phenolic foam not only has good thermal insulation properties but also can be composited with steel plate and other materials, A class thermal insulation materials that reach A class combustion performance include: rock (mine) wool, foam glass, EVB, etc. thermal insulation materials with A class combustion performance mainly include: phenolic aldehyde,gelatine powder polyphenyl granule, etc. thermal insulation material of fire barrier zone can use rock (mine) wool, foam glass, EVB and other materials with A class combustion performance.
Q: Can you tell me the classification of fireproof sealing material.
Fire blocking is to use fire blocking material as partition between cable threading hole and electric hole. Its role is to prevent the cable itself catacausis or outside naked light make the fire spread to achieve the purpose of protecting the safety of personnel and equipment. The principle of fire-proof sealing is plugging material acting as bloating heat absorption and heat insulation. Fireproof sealing material in current market include: fire-proof sealing plate, foam sealing materials, flame retardant module, flexible organic plugging material, inorganic fire sealant, plugging and fire package, etc. The wide usage of fire-proof sealing material in building construction can ensure the fire flame and high temperature flue gas not to extend another fire partition tendril.
Q: What are the requirements for fire?rating of construction suspended ceiling material ?
In fireproof design of all parts in interior decoration, fireproof design of suspended ceiling is the most important. Because the flame is burning up in fire and the suspended ceiling is the first and most direct part to test fire; at the same time, it has a direct impact on the evacuation. Therefore, in indoor suspended ceiling decoration design, fireproof work should be considered fully. Code of fire prevention design of interior decoratio of buildings has detailed provisions for fireproof?performance of indoor suspended ceiling materiial of different civil buildings. Suspended ceiling (sprung roof) refers to the top decoration of a house. Suspended ceiling, an important sub-project in construction decoration project, and the hidden layer of electrical equipment, ventilation and air condition, communication and fireproof, alarm pipelines, etc. has the functions of thermal insulation, sound insulation and absorption. Suspended ceiling plays an important role on the entire house decoration. Proper decoration to the house top surface, can not only beautify indoor environment, but also create a colorful interior artistic image. When choosing decoration materials and design of suspended ceiling, you should follow the principle of saving material, being solid, safe, beautiful and practical.
Q: Who knows about the B-level fireproof insulation materials?
Commonly used B-level materials: Molding polystyrene foam, extruded polystyrene board, gelatine powder polyphenyl granule heat insulating slurry. Although the polyurethane is not the commonly used material, but the 9mm composite of monolayer gypsum board and PU insulating material can reach B-level.
Q: Who knows what fire heat preservation material are there?
Organic material, polystyrene board, plastic extruded board, phenolic resin. Sea capacity module (fire insulation materials fire performance can reach the B1 level, thermal conductivity is only 0.028w\m - K is a good choice, class A fireproof materials now is the mainstream rock wool (mineral wool is wool). A1 fire resistance The largest manufacturer is Thai stone rock wool Co. Ltd.
