Q:Can you tell me the classification of fireproof sealing material.
Organic fireproof sealing material include: fire-proof sealing plate, foam sealing materials, flame retardant module, flexible organic plugging material, inorganic fire sealant, plugging and fire package, etc. Organic plugging material take organic materials as the adhesive with certain flexibility or plasticity when used. The product is thick liquid or cement. Inorganic plugging material take powder of solid inorganic material as the main ingredients, and admixture mixed use, with proper workability. Fireproof bag apply bag shaped object made up by fire-proof materia to large hole fire plug or cable tray fire compartmentation (fire package also called as refractory package or fire protection package). Fire modules is made up of fireproof material, which is a solid with a certain shape and size and can be easily cut and drilled, suitable for holes or fire-proof sealing of cable tray. fireproof sealing material is the plank made up of fireproof material, which is a solid with a certain shape and size and can be easily cut and drilled, suitable for holes or fire-proof sealing of cable tray. Foam block after injection holes can lathery foam and seal hole. Sealing strip is made of fire prevention materials with certain geometry shape or flexible coil geometry.
Q:what's the fireproof levels of fireproof and thermal inuslation matertial?
at present,thermal insulation and fireproofing materials on the market include inorganic thermal insulation bead board(Shanghai Benniao construction and energy saving decoration materials company) rock wool (Hebei Shenzhou glass wool products co., LTD.) foamed glass ceramic (Nanjing Institute of Building Research) or sogou search.
Q:What materials are needed to make the amorphous refractory bricks?
Amorphous refractory bricks have good quality, good reputation, complete in specifications,high refractoriness, strong resistance to slag, and long service life. It’s worthwhile.
Q:Does anyone knows which company produces the better refractory materials?
I recommend Xinjiang Yuanyangrefractory material Co., Ltd. Address: Near Xishan Road No.100, Saybagh District,Urumqi. Their products are both in good quality and reasonable price. In addition, there are Xinjiang Zhongwang refractory material factory, Address: Xi hongxi Road No. 769, Urumchi City. They all have a good reputation. You may think about it. 。
Q:Who can tell somthing about how to choose fire resistant rating of fire resistance rolling shutter doors?
There is no necessary connection between them. Different fire resistant ratings of bulidings require different fire endurance of different elemements of buildings. According to the fire endurance, fireproof doors can be divided into A-grade, B-grade and C-grade, whose fire endurance should not be less 1.2h, 0.9h and 0.6h respectively. A-grade fireproof doors can be even applied to the material whose fire resistant rating is at secondary level. "Building Regulations" mention that fire resisting shutter can be used as partition of fire compartment in those places where setting firewalls is not so easy. When using fire resisting shutter whose fire endurance doesn't include unexposed surface temperature rise, it should install closed independent automatic sprinkler system for protection on both sides, and the sprinkler sholud last at least 3 hours.
Q:What are the main characteristics of the sic refractories?
1. The usage temperature of silicon carbide refractory is generally 1760 ℃ 2. The silicon carbide refractories can withstand dramatic changes in temperature, and a good thermal shock resistance performance. To prevent the cracking or breaking of lining refractories. 3. Under the conditions of high or low temperature, it can withstand a certain compressive stress. 4. Under the conditions of high or low temperature, it can withstand friction. 5. It can withstand the huge hydraulic pressure or buoyancy of the metal. 6. It can also withstand the effect of furnace gases to prevent the infiltration of other refractories and reactions.
Q:Who knows about the types of Dalian thermal insulating and refractory materials?
(1) rock wool board: the heat conductivity coefficient is 0.041-0.045. It is fire retardant, has a great temperature absorption while a poor thermal insulation performance. (2) glass wool: it is simple in construction and free in cutting. It has advantages of antibiosis, mould proof, aging resistance and anticorrosion, and can ensure a healthy environment. It has a low hygroscopicity and a stable physical property. (3) expanding polystyrene board(EPS board): thermal conductivity: 0.037-0.041, it has a good thermal insulation performance, cheap price but a poor intensity. (4) extruded polystyrene board(XPS board): thermal conductivity: 0.028-0.03, it has a better thermal insulation performance, high intensity, moisture resistance while it is expensive, and requires surface treatments during construction. (5) gelatine powder polyphenyl granule heat insulating slurry: heat conductivity coefficient: 0.057-0.06, it has a good flame resistance while a poor thermal insulation performance, as well as has high construction requirements and can be recycled. (6) polyurethane foam: heat conductivity coefficient: 0.025-0.028, it has advantages of waterproofness, thermal insulation, high intensity, high integrity, and good integrity, but it has a poor fireproof performance and is more expensive. (7) rigid polyurethane: heat conductivity coefficient: 0.018-0.023, it has advantages of low heat conductivity coefficient and good thermal performance. When the unit weight of rigid polyurethane is 35 to 40kg per cubic meters, it is equivalent to half of the EPS. It is the one with the lowest heat conductivity coefficient among all the thermal insulation materials. (8) perlite slurry: heat conductivity coefficient: 0.07-0.09, it has advantages of fire and high-temperature resistance, and high water absorption but is poor in thermal insulation.
Q:What are the differences between thermal insulation material and refractory?
Just as its name implies, Thermal insulation means that it doesn't conduct heat instead it insulates heat inside, while refractory means resistance to high temperature and it will not be out of shape or damaged due to high temperature.
Q:What does fire-resistant insulation coating have?
Refractory thermal insulation material mainly refers to the inorganic thermal insulation material and composite thermal insulation material. According to the shape, it can be divided into: Finishing of fibrous shape, mineral cotton, rock wool, glass wool, aluminum silicate wool, ceramic fiber, etc. Diatomaceous earth of microporous pile, calcium silicate, expanded perlite,expanded vermiculite,aerated concrete, etc. Foam glass of bubble shape, volcanic ash glass, foamed clay, foamed concrete, gelatine powder polyphenyl granule heat insulating slurry of pasty form, etc. Their common feature is fire-retardant and firproof. It can be used in buildings with high requirements of fire rating. Calcium silicate, aluminum silicate and asbestos can also be used for piping insulation of heat transport with high temperature.
Q:What are the components of refractory clay?
It is different from non-cement castable refractories, which does not rely on the addition of cement for combination, instead it uses chemical binder. It is refractory castable (also known as chemical bonding castable). Non-cement refractory castable takes oxide or synthetic compound ultra-fine powder or oxide sol-gel which is similar to the chemical composition of material in tungsten castable. Since the use of superfine powder or sol as binder, it has low impurity content, and therefore the refractoriness and slag erosion resistance of the castable will not be reduced. Besides, the self combination in use can help to improve high-temperature structural strength. Non-cement castable refractory is made up of refractory aggregate and powder, superfine powder of oxide or sol, trace amount of dispergator (or anti-coagulant) and proper slow acting hardener. Non-cement castable is mainly coagulated and combinated by ultrafine powder of oxide or sol, therefore, it has certain requirements for ultrafine and sol. Ultrafine powder used refers to less than 1 / zm particles. Ultrafine powder used in non-cement castables are SiO2, Al2O3, Cr2zrOz, etc. SiO micro powder is often adopted, which is the dust recycled during the smelting of metallic silicon, ferro-silicon alloy, the generation process is as follows: This recycled SiO2 powder has an average particle diameter of 0.5 pM, and it is spherical with large surface area. It is amorphous substance with high activity, so it has good bonding strength. The sol used are mainly alumina oxide and silica sol. Silica sol is made by ion exchange of sodium silicate after Na ions are removed. It can also be made after hydrolysis of ethyl silicate. There are several ways of preparing alumina sol, the easiest method is to prepare by the reaction of metallic aluminum or alchlor with hydrochloric acid.
