White Fused Alumina GOOD QUALITY Made in China

Q: What is the common inorganic fireproof and thermal inuslation matertial?: Ceramic foam insulation board is made from clay tailings, ceramic broken flake and river silt, which is the closed ceramics material with high porosity roasted in high temperature by advanced production technology and foam technology. Products have fire retardant, small deformation coefficient, aging resistance, stable performance, good environmental protection, good compatibility between wall base and plastering layer, good safety and soundness and a lifetime as long as the building itself.

Q: Do you know what the main indicators are for the inspection of refractory materials? Thank you very much for your requests and reports: Porosity, volume density, water absorption, true density, thermal expansion, thermal conductivity and heat capacity.

Q: What is streaming fireproof material?: Since streaming fireproof material has less surface energy, so when it is placed in a location to be used, it can be automatically filled so long as mixed with water at proper ratio. And then using vibrator or vibrostand and other tools to compact the mixture so as to satisfy the use requirements. Therefore, it does not require vibration, and it has less friction force between the particles. Generally hydraulic refractory castable must be mixed with water at proper ratio when in construction . While, the concept of "streaming" is in terms of refractory castable.

Q: Urgent question: could you tell me that the export of refractory materials to Vietnam is to be packed in wooden cases and smoked?: See which port, if it is from the border (Pingxiang, Dongxing port), will not be needed.

Q: Which industry does refractory belong to? Does it belong to construction industry?: I am engaged in construction. Refractory material does not necessarily belong to construction industry. Fire resistance is only a part of material?performance. Indeed, there are many places requiring refractory accorded with fire resistant level.

Q: what's the fireproof levels of fireproof and thermal inuslation matertial?: 1, organic materials: B level material is flammable, B1 level material is flame retardant. 2, inorganic materials: Grade A flame-resistant materials are divided into three classes and two kinds of materials.

Q: Does anyone know what is a lightweight refractory material?: Heat preservation and insulation layer used only for Thermal Equipment has poor wear resistance, loose organization and high porosity(40%~85%) . The definition of light refractory material: low thermal conductivity, good performance in thermal insulation , weak mechanical strength, low volume density(generally below 13).

Q: What are the differences between first-level fire-resistant materials and second-level fire-resistant materials?: 1, these refer to fire resistance rating of building materials. 2, As for steel, elements that used in different parts should reach different duration of fire resistance according to fire resistance rating. For example, fire resistant pillars of first level can endure fire within 3 hours; the second level, 2.5 hours; the third level, 2 hours. With respect to beams, three levels of fire resistance are included.

Q: What are the commonly used fire protection materials: Firewall. The fire wall is made of non combustible material, and is directly installed on the base of the building or the reinforced concrete frame or fire proof walls . Fireproof limit of the firewall, according to the current "building regulations", is 4 hours, wheras the specification of Technical specification for concrete structures of tall building is 3 hours. doors resistant to fire, heat in a certain period of time These door usually prevent the spread of fire and gas in the fire resistant wall, staircase, pipe well. Fire door can be divided into steel fire doors, wood fire doors and composite materials fire door according to the material used. According to the limit of fire resistance can be divided into the class A fire door (1.2h), B fire doors (0.9), class C fire door (0.6h); (3) fire window. Windows resistant to fire, heat in a certain period of time It is usually installed in the fire resistance wall or doors; the fire shutter. This roller shutter can be refractory in a certain period of time. It is typically used for heat and fire insulation in escalator with difficulties to install fire resistant wall, fire resistant valve and smoke resistant valve. Fire resistant valve is installed in the ventilation and air conditioning system of air supply and return air duct, usually in the open state, fire, It will be turn off when the pipeline gas temperature reached 70 degrees, can meet the requirement for fire resistance and insulation for gas and fire. Smoke fire resistant damper installed in the exhaust system pipe, when the pipeline gas temperature reached 280 degrees, it will close automatically, insulating fire and gas.

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.
