Q:what is the grading standards of external wall thermal insulation materials?
1. combustion performance of insulation material rates A EPS sea capacity module, rock wool, glass wool, foam glass, ceramic foam, foam cement, perlite obturator, etc. 2. combustion performance of insulation materials rates B1 Extruded polystyrene board (XPS) after special treatment / Special treatment of polyurethane (PU), phenolic aldehyde, gelatine powder polyphenyl granule3 combustion performance of insulation material rates B2 Molded polystyrene board (EPS), extruded polystyrene board (XPS), polyurethane (PU), polyethylene (PE), etc. See the 2009 edition construction technical measures 4.3.6 A graded insulation material is fire proof, but its thermal insulation performance is not so as organic XPS \ EPS. I feel the best insulation materials are Hairong EPS module. it is both insulating and fireproof and cheap. Insulation materials in the domestic market each has its shortcomings. Choose of materials should based on actualities in construction.
Q:what's the varieties of fire-proof sealing material?
Fire blocking material currently on the market include: fire stopping board, foam blocking material, flame resisting module, fire-resisting sealant, flexible organic caulking, WXY-II and fire retardant bag, etc. fire-proof sealing material is widely used in building construction and can ensure high-temperature flame and smoke from fires not spread to another fire compartment, different buildings generally use different sealing methods. Pipeline is generaly sealed by pouring concrete board or mortar.
Q:What is the role of the vermiculite fireproof material?
It can be widely used in construction, decorative ceiling, wall, floor and fireproof door . Especially suitable for airport, railway station, passenger terminal, exhibition hall, hotels, shopping malls, hotels, and other public places and factory, fuel warehouses which have high requirements for fire proofing, etc. With its special thermal insulation, it can also be made to the various types of heat insulation board offered to machines (such as a variety of industrial furnace and assembly line equipment) and furniture, etc. Due to the low density of the product itself, a lot of shipyards in foreign countries use it as ceiling, wall and deck, so the development potential of the domestic shipbuilding market is huge.Expanded vermiculite is porous, lightweight, and dystectic, the most suitable for insulating materials at high temperature (below 1000℃) and fire insulation materials. In the experiment, 15cm- thick cement vermiculite burns for 4-5 hours under 1000℃, but the back temperature is only 40℃. 7 cm-thick vermiculite slate burns for 5mins through the fire flame welding net under 3000℃, the frontage melted, but you don’t feel hot with your hands holding the back side. According to aforementioned, vermiculite slate is superior than all insulating material, such as asbestos, and diatomite products.
Q:The manufacturing technique of refractory material
Melt blowing method is to melt the ingredients first, In addition, hiphotos, organic impurities, to be mixed, add sulfite pulp waste liquid into magnesia billet , ensure the accuracy of the product dimension. The products are mainly used for light refractory. then dry and fire with sintering to reduce the firing shrinkage of products, making it disperse into fiber or hollow sphere. The porpose of pre sintering raw material is to Sintering method is pre-sintering part of the raw material into clinker. such as adding binding clay into aluminum silicate blank
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:What are the commonly used admixture for alumina-magnesia refractory? What are the impacts on its performance?
2, form Mg-SiO2 coagulation and combination, CA cement bond? Bricks can generally be made by combing with phenolic resin, castable use 1, combined with silicon powder; 3, can also combined with brine MgCl is binding agent
Q:what kind of refractories is used to make the industrial silicon furnace mouth long life?
Fused zirconia corundum brick, the smelter of the glassworks is used this kind of lining, and you can contact by private letter.
Q:How many fire endurance grades are the AAA fire resisting shutter divided?
The different fire resistant levels of the building have different requirements of the fire endurance of the building component. According to the fire endurance, the fire doors can be divided into Class A, Class B and Class C fire doors with the fire resistances are not less than 1.20h, 0.90h and 0.60h. Even the fire resistant level of B can also use the first rate fire resistant door.
Q:What is fireproofing material? Are fireproof materials the same thing with thermal insulation materials and refractories?
Insulation materials. Thermal insulation material is characterized by thermal insulation, which is one of the four traditional inorganic nonmetallic materials. Fire retardant material is cahracterized by heat-resistant. Refractory is a kind of materials of resisit high temperature. Fireproof material, which is different from thermal insulation material and refractory, is a synthetic material with some fireproof subtrate added. It is essentially resistant to high temperature.
