Q: who knows the fire resistant levels of fireproofing glass?: According to the fire resistance levels, it can be divided into three categories: Class A: a kind of fireproofing glass that can satisfy the requirements of refractory integrity, refractory and thermal insulation at the same time. Including composite flameproof?glass and perfusion type fireproofing glass . This kind of glass has the properiyies of transmittance, fireproofing ( smoke insulation, fireproofing, and keeping out thermal radiation), sound insulation, shock resistance, and it's suitable for steel and wooden fire door of building decoration, windows, varnishing, partition walldaylighting?roof,ceiling?screen,perspective floor and other construction components demading for transparency and fireproofing. Class B: Marine fireproofing glass, including porthole fireproofing glass and rectangular window fireproofing glass, surface glass pane is tempered safety glass, the inner surface glass pane material can be arbitrary selection. Class C: it's a kind of monolithic fireproofing glass that only satisfies the requirements of refractory integrity. This kind of glass has characteristics of transmittance, fireproofing, smoke insulation and high strength,etc. It's suitable for fireproofing glass partition wall, fire Windows, outside curtain wall and other places without insulation requirements.

Q: What is unshaped refractory?: Castable. Castable refractory material factory to provide raw materials and ingredients, field processing, vibrator for compacting, maintenance must be after heat treatment, due to site conditions quality is not stable, but the integrity of the castable in concrete, two aspects of concrete as water and heat castable quality, raw materials the consumption ratio of concrete is 5% ~ 8%.

Q: What does the function of SiC for refractories?: Silicon carbide for machine non-metallic materials with high temperature wear characteristics of silicon nitride bonded silicon carbide ceramic cups and other products in a blast furnace ladle brick aluminum silicon carbide as an antioxidant added MgO-C

Q: Who knows about ranking rules of fireproofing thermal insulation materials for exterior wall?: You can try the following way to give a brief introduction of the fire?rating classification of external wall thermal insulation materials. 1. the building materials are divided into following categories in terms of combustion performance according to the national standard of GB8624-97. A-level： Incombustible building material: materials almost don't burn. B1-level: nonflammable building material: these materials are good at resisting flame. It is difficult for them to burst into fire when coming across open fire in the air or at high temperature. It will not quickly get wilder and when the fire source removes, it will be extinguished immediately. B2-level: Combustible building material: combustible building materials can play a certain role in flame resistance. It will immediately burst into flames when coming across open fire or at high temperature, and will lead to fire spreading, such as wooden column, timber roof truss and timber beam as well as stairs. B3-level: Inflammable building material: Inflammable building materials are highly flammable with no flame retardant ability. The fire risk is high. 2.The exterior wall thermal insulation materials can be classified according to fire rating. 1). Insulation materials with A-level combustion performance: rock wool, glass wool, foam glass, foamed ceramics, foam cement, hole-closed perlite, etc. 2). The insulation materials with B1-level combustion performance: specially-treated extruded polystyrene board(XPS)/ specially-treated polyurethane(PU), phenolic aldehydegelatine powder polyphenyl granule,etc. 3). Insulation materials with B2-level combustion performance: molding polystyrene board(EPS), extruded polystyrene board(XPS), polyurethane(PU), polyethylene(PE), etc.

Q: Detailed description of magnesia dolomite refractory material?: The CaO of magnesia dolomite refractory is beneficial to the purification of molten steel. In the aspect of smelting clean steel, magnesia dolomite refractory also has good dephosphorization and desulfurization effect.

Q: Can refractory be used as sealing element?: It can. For example, a kind of irregular part that is made of fiber or some injection mix is used for sealing things.

Q: which is better as household fireproof material ?: If it is from the perspective of fire rating inorganic active insulation material for wall thermal, cement foam insulation board, glass beads of insulation movitrified?micro bead?thermal insulation?mortar, rock wool board, glass wool board, ect.. thermal insulation material are Class A fireproofing, polyphenyl board, extruded sheet, phenolic foam board, Polyurethane board, ect..belong to B1 level fireproofing, if it is used for external wall thermal insulation in decorative board, then rock wool board is more often used.
