$High Quality Refractory Castable For Cement(Low Iron)$

Q: In entering fire door, which material does well?: Entering door has two kinds: security doors, fire security door. The pure fire door does not have anti-theft function. In the relevant technical standards of fire doors : when in the fire, it can make residents in a few seconds or 1 minutes forget to open the door... The material of fire door, fire door has steel fire door and wooden fire door. There is no doubt that wooden fire door can't be used as entering door. In the steel fire door, two layers of steel plate in the clip is flame retardant material.

Q: I want to consult the fire resistant level standards of external wall thermal insulation materials.: Fire resistant level standards of external wall thermal insulation materials: 1, The thermal insulation material that has A-class combustion performance: Spraying inorganic fiber, glass wool, foam glass, ceramic foam, rock wool, foam cement and perlite obturator, and so on. 2, The thermal insulation material that has B1 level combustion performance: Special processed extruded polystyrene board (XPS) / special processed polyurethane (PU), phenolic and polystyrene powder. 3, Thermal insulation materials that have level B2 combustion performance: Molded polystyrene board (EPS), extruded polystyrene board (XPS), polyurethane (PU), polyethylene (PE), etc.

Q: Who knows the fire resistant level of the rock wool color plate?: Hello; Same with other unprotected steel, the fire endurance of the color steel?plate is generally 15 minutes. It is not a fireproofing material, let alone fire resistant level. If the color steel plate has sprayed fire retardant coating and the thermal insulation filling material in the core is rock wool fiber, it can achieve A level fireproofing requirements. The color steel?plate refers to the painted steel plate, which is a steel plate with organic coating. The color steel board is divided into the single plate, color steel composite board, floor support board, ect. It is widely used in large public buildings, public plants, portable dwelling, and integrated housing walls and roofings. I hope that will help you.

Q: What are the raw materials of refractory?: Of course, different types have different raw materials: Magnesite (the electric?smelting: alkaline refractory, magnesia-carbon bricks, alkaline, high-purity) + crystalline flake graphite + phenolic resin + additive (silicon powder, aluminite powder, silicon carbide powder, or high-temperature asphalt,etc.) , acidic refractory: The neutral is not easy to answer. such as. You can check out the classification, such as

Q: What are the common refractory insulation cotton material?: Fire resistant thermal insulation material mainly refers to inorganic thermal insulation material and compround thermal insulation material. According to the shape can be divided into: Fibrous finishes, slag wool, rock wool, glass wool, aluminum silicate cotton. ceramic fiber, micro pile of diatomite, calcium silicate, expanded perlite, expanded vermiculite, aerated concrete etc., foam like bubble glass, volcanic ash glass, foam clay, foaming concrete, paste powder polystyrene particles insulation slurry Their common characteristics is fire resistant, applicable for buildings that have high requirement for fire resisitance level. Calcium silicate, aluminum silicate, asbestos, etc. can also be used for thermal insulation of high temperature heat transfer pipe. I hope my answer can help you

Q: Does anyone know about the A-level fireproof materials?: A1-level fireproof materials include: 1. inorganic materials: glass wool, rock wool, foam glass,etc. 2. organic materials: phenolic foam insulation composite board. I hope my answer can help you.

Q: What 's the highest temperature can magnesium plate glass resist ?: You just need a fire-resistance board thicker than 10 mm ,remember to add more perlite as filler during production , 12 mm plate is 80 yuan.

Q: What is the fireproofing requirements of external wall thermal insulation materials?: External wall thermal insulation materials fire rating regulations, 1, the height of a building is greater than or equal to 100m , the combustion performance of insulation materials should be level A; 2, the height of a building is greater than or equal to 60m but less than 100m, the combustion performance of insulation materials should not be less than the level B2. When using level B2 thermal insulation material, every layer should set horizontal fire barrier zone 3,The height of building is be equal or greater than 24m but less than 60m, the combustion performance of thermal insulation material should not be less than the level B2. When using level B2 insulation material, each two-layer should set fire barrier zone ; 4, the height of building is less than 24m, the combustion performance of insulation materials should not be less than the level B2. Besides, when using level B2 thermal insulation material, each three-layer should set a horizontal fire barrier zone.

Q: What are grades of refractory materials?: Refractories have lots of varieties which all have different purposes. It is necessary to classify refractories scientifically in order to scientifically study, choose and manage them. Classification methods of refractories include chemical properties classification, chemical composition of mineral classification, manufacturing technique classification, morphology of the material classification. 1 divided according to the level of refractoriness: ordinary refractory materials: 1580 ℃ ~ 1770 ℃, advanced refractories: 1770 ℃ ~ 2000 ℃ and super refractories: above 2000 ℃ 2, divided in accordance with shapes and sizes : Standard ones: 230mm × 113mm × 65mm, no more than four ruler.
