Q:Does anyone know the refractory temperature of fire-resistant glass?
Ordinary glass will burst under sharp temperature difference of about 70-120 degrees and toughened glass of 200 degrees. It is not yet clear for the bursting temperature differences of the refractory glass. If the overall glass is heated evenly, it will have no significant change below 600 degrees, and it will deform with the increase of temperature until melting. The fire-resistant time of the glass you said is the time to heat the glass into the extreme temperature differences it can endure, which should not be more than 10 minutes
Q:How to divide the fire resistant level of construction thermal insulation materials?
1, Combustion performance of the national standard building materials are divided into the following levels: Class A: incombustible building material: Material that almost never burn. Class B1: nonflammable building material: Nonflammable materials have good effect of flame resistance. In case of fire it in the air or at high temperature it is difficult to catch fire and spread, and when the fire source is removed, the combustion can stop immediately. Class B2: combustible building material: Combustible materials have good effect of flame resistance. In case of open fire in the air or at high temperature, it will immediately burst into flames and spread the fire quickly, such as wooden column, timber roof truss, wooden stairs, etc. Class B3: flammable building material: No flame-retardant effect, highly flammable, high risk of fire. 2, According to fire rating, external wall thermal insulation materials can be divided into 1) thermal insulation material with class A combustion performance. Rock wool, glass wool, foam glass, foamed ceramics, foam cement, hole-closed perlite,etc. 2) thermal insulation material with class B1 combustion performance: Extruded polystyrene board (XPS) after special treatment /polyurethane (PU) after special treatment , phenolic aldehyde, gelatine powder polyphenyl granule, etc. 3) thermal insulation material with class B2 combustion performance: Molding polystyrene board (EPS), extruded polystyrene board (XPS), polyurethane (PU), polyethylene (PE), etc.
Q:What advantage and disadvantages it has compared to common fire insulation materials
Main advantage of A-level fire proof heat retaining plate is A-level non-conbustibility. Now residential areas strictly require the external walls to be high-level fire proof, to be specific, high fire resistance, non combustible. Standards for evaluation varies according to different types, which includes anti-corrosion, acid and alkali resistance, waterproof, anti termites and so on. Disadvantage is the insulation effect is quite ordinary. It will absorb water, get deformed, need some water prevention measures after constrcuting thermal insulating layer for it. Its thermal conductivity far below the benzene plate, and plastic extruded palte, half the thickness of the polyurethane insulation layer can reach heat perservation effectiveness of the benzene plate and extruded plate of the same thickness.
Q:How to divide the fire rating standards of insulation materials?
The fire rating classification standards of insulation materials, 1. Insulation materials with A-level combustion performance: inorganic fiber spraying, rock wool, glass wool, foam glass, ceramic foam, foam cement, close-celled perlite, etc. 2. Insulation materials with B1-level combustion performance: specially-treated extruded polystyrene boards(XPS)/ specially-treated Polyurethane(PU), Phenolics, Polystyrene rubber powder particles,etc. 3. Insulation materials with B2-level combustion performance: Expanded polystyrene sheets(EPS), Extruded polystyrene board(XPS), Polyurethane(PU), Polyethylene(PE), etc.
Q:what is the Specifications Grading for Fireproof rubber insulation materials ?
External insulation materials, welded wire mesh matt external wall insulation, external wall thermal insulation mesh matt. 1,inorganic activel thermal insulation materials 2,silicate thermal insulation material 3,ceramic thermal insulation 4, gelatine powder polyphenyl granule, 5,teel wire gauze picking cement cystosepiment(Estazolam platepowder particles)6 extruded sheetXPX. 7,Rigid polyurethane coating at the scene, Polyurethane insulation board8,rigid polyurethane foam,9EPS foam board roofing materials. 1, a ceramic insulation board 2, xps extrusion board 3, perlite and perlite brick 4, vermiculite and vermiculite brick heating, air conditioning Material: Phenolic resins, polyurethane waterproof thermal insulation integration, sponge rubber, polyethylene, polystyrene foam, glass wool, rock wool Steel material: Polystyrene, extruded sheet, polyurethane panels, glass wool carpets and the like. Five inorganic thermal insulation materials: Foam cement, DY inorganic active insulation system super thin vacuum insulated panel for building external walls .
Q:Can anyone tell me what material the first rate fire resistant door is?
Material of Class A fire doors can be divided into steel and wood, so fire doors can be divided into fireproof steel door and fireproof wooden door. In fact, fire doors of all classes are divided into steel, wood, steel and wood, and other materials (see GB ). Mainly depending on what kind of material the customers want. The fire door is called class A fire door not because of the material but because of the fire-resistant time. The fire resistant time of class A fire door is not less than 1.2 hours and fire doors as long as meeting this condition can be called class A fire doors . The filling material in class A fire doors is generally perlite, whose difference is in thickness. A few of them will use fireproofing materials like foam core board, vermiculite fireproof board, MC composite material and so on. The thickness of class A fire door is usually 50mm. I hope my answer can help you.
Q:Which brand of refractory fiber hard thermal insulation board is better?
Luyang ceramic fiber semi-hard board is good for it has typically applied major technological performance industrial furnaces backing, wall lining, lining material, electric heating furnace backing lining heat insulation ceramics shuttle kiln, backing lining of tunnel kilnand roller kiln.
Q:What characteristics do A grade external wall fireproofing material have?
1. Save space and reduce costs; 2. Fireproofing, green and environmental protection; 3. Waterproofing; 4. Sound insulation; 5. Thermal insulation; 6. Install easily and shorten the construction period; 7. High safety performance.
Q:Is fireclay poisonous?
Refractory materials are typically oxides, alumina, magnesium oxide and aluminate cement and etc, which are non-toxic.
Q:What the fireproofing materialare of the refractory kettle and where they can be sold?
Many places sell these. Nearly 10 years, can't brun when it is dry, adsorption. You can also baidu these materials. Heat transfer evenly, feldspar, clay and other raw materials with a ceramic products. Traditional casserole can not resist heat difference and also can withstand for 100 high temperature without crack. Aiming at the problem of traditional casserole, easy to crack and air permeability, people joined the spodumene on raw material, produce a high-temperature resistance casserole. It is produced after the high temperature burning makes an earthenware pot to keep the original advantages. Hebei has many places to sell these materials and is also relatively cheaper. The traditional casserole has features of not easy to transfer heat's quartz and slow cooling. Due to production technology and raw materials, it greatly improves the casserole' practicability after research and improvement.
