Q: What is the main constituent of refractory brick?: The main constituent of silica?brick is monox, etc. Refractory bricks have many kinds of texture. The main constituent of high alumina brick and clay brick is aluminium oxide. The main constituent of every texture is different. The main constituent of magnesia bricks and magnesia-chrome bricks is magnesium oxide.

Q: For refractory, what is critical particle size? Thank you.: Critical granularity means the maximum size of particles in refractory.

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 industry does the metallurgy and thermal insulating and refractory material belong to?: Materials Industry

Q: Does refractory belong to stone, building materials or other?: It belongs to metallurgy and building material industries.

Q: What's the B grade fireproofing material?: Grade B: rubber and plastic, extrusion molding, polyphenyl, PEF. organics, extruded sheet, polyphenyl board, phenolic resin. Hairong modules (thermal insulating and fireproof material) can reach grade B1 in fireproof performance.

Q: How to deiron refractory?: Deironing refractory can take physical methods into consideration, such as magnetic?separation, reselection, etc. And it can also take chemical methods, such as flotation.

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: How many fire endurance grades are the AAA fire resisting shutter divided?: 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: Firing high temperature kiln of refractory and internal temperature being as high as 1600 ℃, metal heat exchanger can't use, how to do?: 1>3>。 When metal heat exchanger is in 700 ℃, it must process high temperature protection, mixed cold wind or cold blast to protect heat exchanger. So this will waste a lot of energy; The comparison of high temperature resistant ceramic heat exchanger using temperature is 1350 ℃ to 1450 ℃; metal heat exchanger using temperature 700 ℃; heat utilization comparison of ceramic heat exchanger can be placed in 1350 ℃ or higher (highest available to 1450 ℃); the oxidation resistance, a very short time will burn out;2 >, waste heat recovery rate is high. Replacing the metal heat exchanger in high temperature and corrosion environment; Comparative ceramic heat exchanger can be used under the condition of 1350 ℃ for a long time. Let's make a comparison, if it is a refractory material industry. <, ceramic heat exchanger is simply won't appear, under the condition of equal to ceramic heat exchanger using, energy saving effect is best, can exchange for the high temperature. <. Ceramic heat can be placed on the nearest of exchanger flue outlet . <, and metal heat exchanger put in place contrast to the ceramic heat exchanger. In the process of using metal heat exchanger, if this situation happens, you can consider the ceramic heat exchanger. Temperature difference is between 650 ℃ to 750 ℃. If the metal heat exchanger is placed in normal place where ceramic heat usually put;The service life comparison: since ceramic heat exchanger with high temperature resistance, this partly replace metal heat exchanger. What's more, energy-saving rate is also different. Metal heat exchanger can be placed in 700 ℃ or less;4 >, corrosion resistance, its application effect is very different. So the metal-heat-exchanger's heat-resistant temperature is high and the service life is the countless times of metal heat exchanger. The place with highest temperature does not need high temperature protection.
