- Q: The fire prevention board line is made of what material?
- Crural line: wooden, in the market, there are sjoiner woodblock, peach wood and artificial engraving. The second classification is stone and the most used one is the marble graved or ceramics well-made one is taken as the first choise. Its price is a little bit expensive than the wooden one, but also a suitable choise. Condole supports: It has various category. The general furniture choose plaster and anti-firing plate and the other also have a choice of steel. You can make a suitable choice according to the need. If it is contracting project, it depends on your project specific plan and funds plan. In a word, beauty and harmony should be given priority since it is the source of design.
- Q: How to divide fire rating of decorating materials ?
- Generally speaking, it is divided into Level A: noninflammability; B1: difficult-flammability; B2: combustibility; B3: inflammability.
- Q: How much modulus is used as refractories material of sodium silicate.
- Storage and use are very convenient, especially for mechanized and the evenly refractory material and the sodium silicatemodulus is generally...2. transportation. The appearance of product is pure white. Instant powdered sodium silicate, also known as instant sodium metasilicate.4 to 3, in powder form, automation. in the range of 3, hydrated sodium silicate
- Q: What dose the fireproof and thermal insulation material include?
- It includes A1: Non-combustible inorganic monomer; A2 Non-flammable organic compound, namely composite material; A3 Modified phenolic fireproof materials.
- Q: Manganese steel belongs to refractories
- NO!
- Q: what is the fireproofing material of engine room? who knows it ?
- machine room fireproofing materials include: Inorganic binder: The main material includes sodium silicate, gypsum, phosphates, cement,ect.; refractory mineral filler: aluminium oxide, asbestos powder, calcium carbonate, perlite, cornstarch, ect.; nonflammable organic resin: it mainly includes polyvinyl chloride, perchloro-ethylene, chlorinated rubber, neoprene latex, epoxy resin, phenol resin, ect.. nonflammable fireproof addictive: it mainly has phosphorus, halogens, nitrogen organic compounds (chlorinated paraffins, tributyl phosphate,deca-brominated diphenyl ether), and boron series (boric acid, zinc borate, aluminium borate), antimony system, aluminium series, zirconium system, etc. inorganic compounds.
- Q: Which are roofing fireproofing material?
- (1) Foamed concrete is a kind of fire-proof thermal inuslation matertial featured by good fire resistance and thermal insulation. Besides, it is also characterized by excellent sound proofing, penetration resistance, easy construction, safety and environmental protection without toxin and pollution. (2) Foam glass is featured by light weight, small heat conductivity coefficient and water absorbption, non-inflammability, fire resistance, high strength, no moulding, corrosion resistance, non-toxin and stable physical and chemical properties and thus widely used petroleum, chemical engineering and underground construction. It is also featured by thermal insualtion, heat/cold preservation and sound absorbption and thus can be used for thermal insulation of external wall and roof of civil builduing. Foam glass is featured by stable chemical property, easy to be processed and not easy to deforme, and durable. (3) With slag, basalt and other natural ore as the main raw material, rock wool, mineral wool and its products are made by high temperature melting into fiber, and then processing with binder. It has low thermal conductivity, fire resistance, easy construction and good effects of energy saving and thus is highly cost-effective. (4) With phenolic foam material as main material, phenolic resin plate is made by foaming thermoset phenolic resin. It is featured by light weight, fire resistance, no burning in the air, no smoking, non-toxin, no dropping and non-embrittlement and thus is an ideal thermal insulation material used in HAVC projects. Due to its high obturator formamen rate, low heat conductivity coefficient, good thermal insulation, water resistance and water vapor permeability, phenolic foam is an ideal thermal insulation material.
- Q: What are the differences between first-level fire-resistant materials and second-level fire-resistant materials?
- Level B1: building materials with flame retardancy: this kinds of materials have good effect in flame retardation. Under the case of open fire or high temperature, it is not easy to be ignited and spread quickly, and when the fire source is removed, fire would stop immediately. Level B2: combustible building materials: combustible building materials also have effect in flame retardation. It will get burnt as soon as it meets open fire or high temperature, so it can easily give rise to rampant fire, such as wooden pillars, wood roof trusses and wooden stairs.
- Q: For refractory, why is it necessary to store the first mixing materials for some time under proper moisture and temperature?
- It is mainly to remove gas form chemical reactions in the pug, give full play to plasticity and binding properties of combined, and store unburned?brick whose cememting agent is phosphoric?acid or aluminium?phosphate for some time under proper moisture and temperature. For example, to avoid the formed bricks in the initial stage of drying and firing form cracking due to hydration of calcium oxide. Mixing materials is to store the first mixing materials for some time under proper moisture and temperature in order to improve the evenness and moldability of pud, such as making the distribution of combined clay and water more even. The length of storing chiefly depends on the process requirements and the characteristics of blanks. For the producing pug of high temperature kiln furnitures, the storing time is longer. The function of storing mxing materials varies with different natures of blanks. For honeycomb ceramics, it is to fully digest calcium oxide in blanks. For storing magnesia brick blanks containing much calcium oxide, it should be stored for some time in proper humidity and temperature.
- 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.
