- Q:Who knows the external wall thermal insulation materials fire rating requirements?
- 1. The thermal insulation material of level A combustion performance: Rock wool, glass wool, foam glass, foamed ceramics, foam cement, hole-closed perlite, etc. 2. combustion performance is level B1 insulation materials: Extruded polystyrene board (XPS) after special treatment / Special treatment of polyurethane (PU), phenolic aldehyde and gelatine powder polyphenyl granule 3, combustion performance is level B2 insulation material: Molding polystyrene board (EPS), extruded polystyrene board (XPS), polyurethane (PU), polyethylene (PE), etc. See the 2009 edition construction technical measures 4.3.6 Level A insulation material is only for fireproofing, but its thermal insulation performance is not better than organic XPS \\ EPS and other materials. I feel the best insulation materials should be modified phenolic board, which can keep insulation and fireproofing, but the unit price is very expensive. Insulation materials in the domestic market have some disadvantages, it is better to considere the materials within the acceptable range in the building needs.
- Q:How many external wall thermal insulation fireproof material are there
- External wall thermal insulation materials are generally divided by the burning grade, into class A, B grade. Grade A is non combustible material, grade B is combustible material. Class A which can be divided into thermal insulation mortar, bakelite plate, rock wool plate, foam cement plate etc.. Insulation mortar is relatively good, easy for construction, convenient, low cost, but its production process is too simple, so it is prone to fake. I recommend you to find a large manufacturing factory that posses complete procedure, for example, provincial production record, the provincial use record, municipal record, tset report at or above the provincial level, state fire proof report, design drawings of office building. product will not be safe if there is a lack of any of these documents. Burning level for henolic is uaually class B, but class A2 can be reached if a thin layer of mortar is applied on the suface,(A1 is the highest level of fire safety),intensity of phenolic is not high, finger pressing will leave a pit on it. if classified according to kilogram, raw material differs greatly every 10 kilogram. Rock wool is also classified by kilogram, general using 150kg wool. Rock wool are now comprounded with average strength. It will easily absorb water, having trouble applying paints. Foam cement strength is not high, easy to absorb water, It is not resistant to falling. It costs low, only used unless little profit can be made, Do not use it if worrying accidents would happen. These materials can be firstly burned, The palce the sample into water to see if it will dufuse at last. External wall should stand up to wind and rain. In terms of thermal insulation, they are almost the same, shows little differences on design thickness.
- Q:what is the original materials of fireproof coating?
- Fire retardant coating is composed of the base materials (that is film forming substance), pigments, ordinary coating additives, fire retardant agent and dispersion medium. In addition to fire retardant agent, other components functions the same as in ordinary coating, but its performance and thickness are specifically required. Some solvent-based fire retardant coating can burn upon encountering fire before construction.In fact,It is the flammable solvent contained in the coating that is burning while substances such as the base materials and fire retardant agent does not burn. Because solvent-based fireproof coating contains organic solvent and these fire-resistant coating, once leaked from the bucket, are likely to cause a fire. Fireproof coating on the substrate can insulate heat only after the solvent contained evaporates compeletly.
- Q:Which fire-resistant materials have good viscidity?
- Viscidity is necessary for gunning mix, repair mix and bordering. It is too broad to which has good viscidity. Both gunning mix and repair mix are powder before adding water. Bordering also has little viscidity before heating. The question shoule be more specific.
- Q:What high-molecular polymers can be used as fire-resistant material binder?
- Lignin is the least expensive.
- Q:What material is used for making refractory stone bowl?
- Good refractory stone pot is carved from high-quality natural refractory stone in a professional way. But many are also made of synthetic materials, the price is lower, too.
- Q:What kinds of refractory materials that uses a-Al2o3 powder? What are the purpose of it?
- 04La-Al2O3 powder is a alumina powder whose raw material is industrial aluminum oxide which has been calcined at high temperature. It is a good polishes for ceramics and jade, meanwhile, it is also an important raw material for high-end refractory materials. The technical indicators parameters A1023 mark A1535 chemical composition AL2O3≥ 99.92 3%, ≥ 3.10FE203≤ 0.799 Refractory calcined alumina powder (a-Al2O3) 1.2 true density (g & # 47, by fully ground powder made of different fineness .O.10 0.07 0.04NA2O≤ 0.93a-Al2O3 (%) ≥ 95 95 primary crystallization average grain (um) 2 ~ 3 3 ~ 5 average particle size (um) 40 ~ 602.6SIO2≤ 0.1 0.15B2O3≤ - 0, glass, engineering ceramics typical use electronic ceramic insulating ceramic refractory ceramic wear 3
- Q:What refractories are used in various parts of the blast furnace.
- Blast furnace from top to bottom has the throat, hearth staves, waist, bosh, hearth and furnace bottom. the specific structure is as follows: The throat is the first to be affected by the impact and abrasion, generally use high-density alumina bricks. the upper and central portion of temperature furnace is only 400 ~ 800 ℃, the area with high alumina bricks and silicate bricks. The lower part of furnace is subject to erosion and dust erosion alkali metal vapor due to high temperatures, it is required in such case to use high quality clay brick,high alumina brick,carborundum brick,corundum brick that is slag resistance and alkali?resistance, temperature resustant and wearproof. Furnace bosh temperature reached 1400 ~ 1600 ℃, serverly eroded by slag,vapor, flush. so we use carborundum brick and reaction-bonded silicon?carbide?brick. Bosh temperature reaching1600 ~ 1650 ℃, using alumina brick, corundum brick or silicon carbide brick. the temperature of Hearth near the upper portion of the outlet zone at 1700 ~ 2000 ℃, use of silicate bricks and corundum castable graphite filler, silicon carbide bricks. In 1450 Silly twitch bottom temperature sealing die of hunger slander bet phoenix astringent preserved Grade ~ 1500 ℃, use of graphite bricks and microporous carbon bricks, now use more corundum brick, corundum mullite brick and synthetic mullite brick. x26lt;P class x3d "share-btn"x26gt;
- Q:what is the material of fixed first rate fire resistant window?
- Fixed first rate fire resistant window is produced by the steel sash windows, steel casement, fireproofing glass. Fireproof windows, is composed by steel window frame, steel casement, fire-proofing glass. it refers to the window which can isolate and stop the fire spreading. The fire window product is named after the main material of window frame and the window casement, window frames is made of steel, casement is made of wood or the sash frame is made of wood and the casement is made of fire window.
- Q:What's meaning of CN of fire-resistant material?
- The commonly used preparation methodsinclude shock compression, high-pressure pyrolysis, ion implantation, reactive sputtering, plasma chemical vapor deposition, electrochemicaldeposition, ion beam sputtering, , low-energy ion radiation, pulsed arc discharge,pulsed laser inducing, etc. But the compounding result of superhard materialis not ideal due to deposition of amorphous CN film, nanometer level sizedC3N4 crystalline grain set in the amorphous film and few large graincrystal.
