- Q: A chemical problem with refractory materials
- In chemistry, there is never absolute
- Q: How many kinds of A-level fireproof and thermal insulation materials are there?
- A-level non-combustible materials are mostly inorganic thermal insulation materials, as well as some organic compound materials can also be non-combustible; but if the convenient construction is required, panels are exempted, you can only choose inorganic thermal insulation mortar.
- Q: who knows how to classify the fire resistant levels of fireproofing material?
- Materials used in construction are called construction materials. The combustion performance of construction materials refers to all physic and chemical changes happened when burning or contacting fire, the properity is measured by combustibility of material surface and flame transmission, heating, smoke,charring, weightlessness, and the producing of toxicity resultant. Our national standard GB8624-97 classifies the combustion performance of construction materials into following several levels. Class A: Incombustible building material, class B1: Nonflammable building material, class B2: Combustible?building?materials, class B3: Inflammability construction materials, generally speaking: first fire resistant level construction is the mixed construction of reinforced concrete structure or brick wall and steel concrete structure; second fire resistant level construction is the steel structure roof truss, reinforced concrete column or mixed structure made by brick wall; third fire resistant level construction is the wood and brick made by wooden roof and brick wall; fourth fire resistant level one is the combustible?structure made by wooden roof, hard-comnustible component wall.
- Q: What are the chemical composition of refractory cement?
- Calcium aluminate prepared by calcining as the main component. Aluminate cement takes bauxite and limestone as raw materials, alumina content of about 50% as the clinker. And it is a hydraulic cementing material made by grinding. Refractory cement is also known as aluminate cement.
- Q: What is the new fireproofing standard of external wall thermal insulation materials?
- The new national standard "Fireproof? Specification of Building Design" (GB50016-2014) has been issued, it will be carried out from May 1, 2015. Compared with "Fireproof? Specification of Building Design" GB 50016-2006 and "fire?safety?rules of tall buildings design" GB 50045-95 (2005 edition), the major changes of new standard is the following: 1. It has combined with "Fireproof? Specification of Building Design" and "Fireproof? Specification of Tall Buildings Design", and has adjusted incompatible requirements between two standards, and has unified the classification of residential buildings in accordance with the building height; 2. It has increased two chapters including the fire-fighting rescue facilities and wooden structures, and has improved the requirements for fire fighting and rescue, and standardized the fireproofing requirements of wood construction; 3. Additional requirements for the fireproofing requirements of building external insulation system; 4. The fire-fighting equipment is written in a separate chapter and improve relevant contents; cancel the design requirements of fire water supply system and smoke control system, and they are regulated by the relevant national standards; 5. appropriate increase in the high-rise residential buildings and fireproofing technical requirements for high-rise civil building whose height is greater than 100m; 6. add the fireproofing requirements used by covered pedestrian during evacuation; adjust and add designers density of construction materials, furniture, lighting shops and exhibition hall; 7. add the fireproofing requirements of underground warehouses, logistics buildings, large combustible gas tank (zone), ammonia storage tanks, LNG storage tank, and adjust the fire?separation distance of liquid oxygen tank; 8. improve the relevant requirements to prevent vertical or horizontal spread of building fire.
- Q: Could you tell me how does fire protection standard of decorative material is divided?
- Building materials can be divided into four levels according to combustion performance (non-combustible, flame retardant, flammable, flammable). According to the Code for Design on Building Fire Protection and Prevention (GBJ16-1987) (revised in 2001):, the fire risk of production or storage is divided into a, b, c, d, e classes. Divided by plate material: structure material, base layel materials and fabric; Divided by fire protecrtion type: easy to burn, difficult to burn, flame retardant, incombustible material. Material has no fire rating, only the different from the time of combustion limit. Combustion performance grade A of commonly used adornment material: granite, marble, terrazzo, cement products, concrete products, gypsum, lime products, clay products, glass, ceramic tile, Mosaic, steel and alloy. I hope my answer can help you.
- Q: Who knows how many poured refactory material are there?
- Pouring refractory material can be classified into the followings according to the body density: Heavy (> 2.0g\cm3), medium heavy (1.0-2.0g\cm3), light (0.4-1.0g\cm3); by binding agent: Combination of hydration, chemical binding, condensation, hydration and condensation: Clay, high alumina, silica, magnesia, alumina magnesia, magnesium and chromium, magnesium zirconium, silicon carbide etc.. Clay brick, high alumina brick, bead brick, silica brick, light mullite, alumina hollow spherical brick, oxidation zirconium hollow spherical brick, corundum brick, magnesia brick, magnesia brick, magnesia alumina spinel brick, magnesia chrome brick and so on
- Q: Who knows about the B-level fireproof insulation materials?
- Organics, extruded sheet, polyphenyl board and phenolic resin. The fireproof?performance of sea capacity module (fireproof and thermal insulation material) is B1-level with the heat conductivity coefficient of only 0.028w / m · k. It is a good choice. A-level: Rock wool, glass wool, silicate, aluminum silicate, calcium silicate, phenolic aldehyde, and foam glass. B-level: Rubber and plastic, extrusion molding, polyphenyl, PEF.
- 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: Where is the development of refractory industry?
- Continuous casting system varieties used in refractory materials include: (1) ladle refractories -- ladle lining, permanent lining, ventilation components; (2) tundish refractories -- linings and coatings, insulation board, cover; (3) functional refractories -- non oxidation casting with long nozzle, immersion nozzle, stopper, sliding gate; (4) purifying molten steel with ceramic purifier, slag dam, alkaline coating and horizontal continuous casting for separating ring gate, etc..
