Q:What 's the highest temperature can magnesium plate glass resist ?
Glass magnesium plate is non combustible plate having good fire-resisitance quality. Flame will never burn continuously on it. It does not catch on fire when temperature reach 800 ℃, and will not be lit up at 1200 ℃. The plate, having high-quality keel partition system, is rated as the highest non-combustible level A1 with fire resistance being above 3 hours. It absorbs a lot of heat when fire is burning, delaying rise of ambient temperature.
Q:What is the criterion of entry of refractory clay industry?
There are two requirements: (a) Enterprises mining and processing high-alumina clay meet the national industrial policy, and in line with the requirements of mineral resources planning and industrial planning, industrial development planning of high alumina clay in provinces (autonomous regions and municipalities), urban planning, the whole land use planning, mineral resources planning, environmental protection and pollution prevention planning. (b) The building of new mines of high alumina clay in areas where exploitation of mines are restricted in national and local level should be strictly limited. It is prohibited to build new mines in areas where exploitation of mines is banned, and the mines have been built should be disposed in accordance with the mineral resources planning and relevant national regulations. It is prohibited to build high-alumina clay production and processing enterprises in special conservation areas such as drinking water source reservation areas, natural reservation areas, scenic reservation areas, ecological function reservation areas, basic farmland reservation areas, cities and their suburbs, residence, schools and kindergartens, health center, hospitals and perimeter 1 km from enterprises having high requirements on the environment such as food, medicine, electronics etc., the both banks of main rivers and roads, somewhere near trunk railways.
Q:Who knows what is the standard of insulation material whose fire proof is level A?
Non combustible materials of level A: WW inorganic active wall thermal insulation material, Cement foaming thermal insulation board, Glazed hollow bead insulation mortar, rock wool board, Glass wool board, Foam ceramic.Non combustible materials of level A, endowed with low density, low thermal conductivity, higher bearing capacity, convenient construction , economy and durability, are widely used in heat pipe, heat equipment, other industrial pipeline equipment , thermal insulating materials on industrial buildings, and used as heat preservation, thermal insulation, sound absorption materials of industrial and civic buildings.Non combustible materials of level A are used more for refractory protection coating material of steel structure because of its good thermal stability.
Q:What is required to do refractory material?
But we can’t exclude that some products may contain a certain amount of metal materials: refractory material is non metallic materials whose physical and chemical properties make it suitable to be used under high temperature. Technically, it needs high purity raw material,high pressure molding, high temperature sintering to make refractory material. Refractory materials have two properties: first, the strong thermal shock resistance, second is slag resistance, the key is to look at what parts does it apply.
Q:Does anyone know fire-proof material of fireproof wooden door?
Fireproof wooden door goes through the flame treatment, so it can prevent fire. Its principle: Fire-retardant treated timber has become flame retardant material itself and its fire endurance has increased. The commonly used method of fire retardant treatment for timber including: Spraying method, soaking method, boiling method, vacuum method, vacuum-pressure method. Spraying method and soaking method are generally used for timber surfaces which are no longer going through planing process, and thin plate fire retardant treatment, whose thickness is less than 10mm .
Q:Can anyone say something about the curtain wall fire-proof material key sealing point?
Keypoints; 1, curtain wall design must consider the safety requirements, one of which is fire protection design. 2, Generally, fire protection planning between curtain walls should use the method of setting fireproof isolation layer. 3, Two layers of fireproof isolation layer whose thickness should not be less than 100mm respectively on the top edge and lower edge of the material parts of the house. 4, the fireproof isolation layer commonly uses 1.5mm thick galvanized steel sheet as supporting plate, using for shelving fireproof sheet. The 100mm thick cavity between the layers is filled with mineral wool non-combustible materials tightly covered with tinfoil on the surfaces. 5, protective isolation layer should try to reconcile curtain wall beam level and finish floor level, so as to fill non-combustible material and to avoid that a piece of glass acrosses two fire compartments. 6, the beam should be inside 100mm thick fireproof isolation layer to protect the beam and the upper curtain wall plate. 7, when there are open fire function areas like large-scale hotel or restaurant kitchen inside the curtain walls, curtain wall glass in these parts should consider using cesium potassium fireproof glass to improve the fireproof rating in the region. 8, Fireproof setting in the around areas of curtain wall can use the same method of the above fireproof setting between layers. The joint parts of fireproof isolaton layer and main part as well as curtain wall should use fireproof sealant to seal.
Q:What is the appropiate thickness if fire resistant time for ultra thin steel structure coating is 2.5 hours?
Hello steel structure can adopt surrounding concrete or brick, fireproof coating, fireproof board coating and composite structure for its fire resisitance. Fire resisitance board can be divided into thick fire protection plate and thin plate, the thickness of the plate thickness of the fire is between 20 ~ 50mm, mainly includes calcium silicate fireproof board and expansion boring stone fire board, the main varieties are KB board, CF; thin fireproof plate is between 6 ~ 15mm thick, the main varieties include enforced short fiber cement plate, ordinary enforced fiber silicate calcium board and glass cloth reinforced inorganic board.
Q:What is the function of refractory material?
Refractory is a basic material in the field of high temperature technology. Generally, the refractory is used as structural material or lining to resist high temperature in various thermal equipment and high temperature container. In the iron and steel industry and metallurgy industry, coke ovens are mainly composed of refractory materials. Various refractories that meet the requirements are essential in blast furnace for ironmaking, hot stove, all kinds of steel-making furnaces, soaking furnace and heating furnace. Not only the die casting for molten steel needs lots of refractory materials, but also the continuous casting needs some high-quality refractory materials. Without high-quality refractory materials, external refining is also not impossible to achieve. Statistics show that the steel industry is the sector that needs the most refractory. Pyrometallurgy and thermal processing of ferrous metal also needs refractories. All high-temperature furnaces or lining in construction materials industry or other high temperature industries that produce silicate products such as glass industry, cement industry, and ceramics industry must be constructed with refractory materials. All kinds of roasting funaces, sintering funaces, heating furnaces, boilers, flues, chimneys and protective layers in chemical, power and machinery manufacturing industry need refractories. In short, when some kind of structures, devices, equipments or vessels are used under high temperature, they all should utilize refractory to resist the high temperature because those materials will deform, soften and fuse or will be eroded, scoured or broken due to the physical, chemical, mechanical effects, which may stop the operation, affect the production, contaminate processed objects and impact the quality of products.
Q:How to choose construction external wall thermal insulation and fireproofing materials?
The width of fireproof partition shuld be greater than 30CM, and the thickness should be the same as total thickness of thermal insulation materials. Fire barrier zone thermal insulation board and base wall should be stuck in whole area. Fire Barrier zone thermal insulation board should be stuck with the assistance of anchor bolt which must press the mesh of the bottom layer. Fire Barrier zone should be set above the door and window, with a distance of less than 50cm between the lower edge of fire barrier zone and the upper edge of window.
Q:What are the materials of class A fire resistant window?
Fixed class A fire resistant window should be made up of steel frame, steel casement, and fireproof glass. Fire windows, made up of steel frame, steel casement, and fireproof glass, refers to window that isolate and stop the fire from spreading. Fire window is named according to the main materials of the frame and casement. Window frame is made up of steel and casement wood, vise versa. I hope it is useful.
