Q:What's the feature of construction external wall fireproof and thermal inuslation matertial?
Building external wall fireproof thermal insulation material is made by stirring, casting, foam protecting and cutting with industrial by-product gypsum as the main raw material, adding sulphate aluminium cement, fly-ash, polymer additives and other materials. It has excellent properties of respiratory function , air permeability, water impermeability, recycling system data, wind load resistance, shock resistance, thermal insulation, fireproof and sound insulation.
Q:Who knows the model of fireproofing materials?
There are many kinds of fireproofing materials, it's hard to discuss it in detail, but i can talk about the PC fireproofing material with you. There are various models of PC fireproofing materials, the materials manufacturer usually used are common materials; it's divided into the following levels according to fire rating: UL94 VO level, UL94V1, general products can reach V2 level. hope it can help you.
Q:Who knows about roof fireproofing materials?
Roof water proofing materials: synthetic polymer waterproof rolls, high polymer modified asphalt waterproof coiled material, sheet metal, synthetic polymer waterproof coating, one-component water curing polyurethane waterproof coating, penetration crystalline waterproof coating. Secondly, we have to choose materials that are suitable for roof water proofing. The right waterproof materials have better waterproof performance, TS-3B one-component water curing polyurethane waterproof coating is very suitable and the performance is good. Since traditional roof waterproofing materials have requirements on the moisture content of the formation level which should be less than 9%. It is really important to choose which materials to repair leaking roofs. Kitchens and toilets are moisture, the formation levels of buildings are hard to satisfy requirements, thus, waterproof layer and formation level are easily get separated and are ineffective in waterproofing.
Q:What are the physical properties of refractory material?
The mechanical properties of refractory material include compressive strength, volume density and sclerosing, slag resistance, elastic modulus, thermal shock resistance, oxidation resistance, bibulous rate, fluidity, resilience, bond strength and slump, electrical conductivity, specific heat, heat capacity, the impact strength, linear change, torsional strength, stomatal aperture distribution, resistance to acid, etc. The use performance of refractory material include refractoriness, thermal emissivity, condensation, porosity, coefficient of thermal expansion. Thermal properties of refractory material include thermal conductivity, temperature conductivity, plasticity, the hydration resistance, creep performance. The physical properties of the refractory materials include structure performance, mechanical properties, shear strength, load softening temperature, CO erosion resistance. The structure properties of the refractory materials include porosity, alkali resistance and sintering. The operating performance of refractory material include consistency, tensile strength, the use performance and operating performance, wear resistance, bending strength, thermal properties.
Q:what kind of fireproof materials is used for high rise buildings?
Recommended thickness of 1mm or more # 304 stainless steel, refractory, corrosion-resistant, easy to clean. closed balcony of high rise buildings use thickened manganese, aluminum profiles. You can also use plastic steel window, solid wooden windows. Mg-Mn alloys have excellent weldability and corrosion resistance, unstressed corrosion tendency. Mechanical properties are not good enough, the ultimate strength of 210 ~ 280MPa.
Q:What types of steel are silicious quicksand and chromium quicksand used in respectively?
Chromium quicksand can be used in steel-making process that has longer refining time like LF, VD and RH, in stainless steel drainage and thin plate drainage agent. Silicious quicksand is used in short steel-making process, process that is less than 45 seconds or process without refining. You can consult Hua Heng for details or inspect it by yourself.
Q:What's the B grade fireproofing material?
B1 grade ceiling material: gypsum board, fobrous plasterboard, cement particle board, mineral wool decorative acoustic panels, glass wool decorative acoustic board, perlite decorative acoustic board, flame retardant plywood, flame retardant medium density fiberboard, rock wool decorative sheet, flame retardant wood, aluminum foil composites, flame retardant phenolic laminate, aluminum foil glass fiber reinforced plastic composite material, etc.; B1 grade wall material: gypsum board, fibrous plasterboard, cement particle board, mineral wool board, glass wool board, perlite board, flame retardant plywood and medium density fiberboard, fireproof plastic decorative sheet, nonflammable double-sided particle board, multicolor coating, flame retardant wallpaper and wall cloth, flame retardant simulated granite decorative plates, magnesium oxychloride cement prefabricated wall panels, flame retardant glass fiber reinforced plastic plates, PVC plastic clapboards, high-strength and lightweight composite wallboards, fire-retardant molded wooden composite boards, flame retardant colored artificial boards, nonflammable glass fiber reinforced plastics, etc.
Q:How long is the fire-resistant time of fireproof wooden door?
The fire-resistant time of fireproof wooden door is about 1 hour. Fireproof wooden door refers to the door whose door frames, skeleton of the door leaf, door panels are made of timber or timber work and fire endurance reaches the provisions of "GB50045-95 design of tall buildings for fire protection". Fireproof door is one of devices for fire prevention and separation of the building, generally used on the firewall, entrance and exit between stairs pipe shaft opening, which plays an important role in the reduction of fire losses.
Q:Could you tell me how does fire protection standard of decorative material is divided?
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. Building fire protection. Building fire protection is the fire prevention measures of buildings. In the architectural design, fire protection measures should be taken to prevent fires and reduce fire hazards to life and property. Building fire prevention measures includs prophylaxis before the fire and measures during the fires. The former is mainly to determine the fire resistance rating and fire-proof structure, control fuel quantity and space easy to fire site; The latter mainly for fire partition, setting of evacuation and smoke, fire-fighting equipment, etc. In ancient China, flammable wood are usually taken as a building material, which has accumulated many experiences for the building fire protection .
