Q:how is the high-temperature flame-retardant fibre board?: high-temperature flame-retardant fibre board is good decorative material. Hope it helps you.

Q:Which brand of thermal insulating refractory is good?: Brands of thermal insulating refractory: 1, Armaflex(German brand). Manufacturer: Armacell thermal insulation materials (Guangzhou) Co., Ltd, Armacell thermal insulation materials (Suzhou) Co., Ltd. 2, Durkflex (American brand) Manufacturer: Durkee (Guangzhou) thermal?insulation?material Co., Ltd. Durkee (Wuhan) thermal?insulation?material Co., Ltd. 3, Aeroflex (Thailand Brand) Manufacturer: Aeroflex Polymer Technology (Shanghai) Co., Ltd.

Q:What are the qualifications of refractory industry?: Special qualification issued by Fire department

Q:Is the refractory reached British BS standard and used for cables in China at present ceramic silicone rubber?: Which standard? Please be more specific

Q:who knows the fire endurance of fireproof coating?: this is not specfied , depending on design requirements. The products we made have fire endurance from 1to 4hours . We have not done any higher.how is the fireproof coating in improving fire resistance of building components? finishing fireproof coating; wood fireproof coating; fire-resistant coating for steel structure, fire-resistant coating for concrete structures, tunnel fire retardant paint, fire retardant paint for the cable. 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.

Q:What is the function of refractory material?: Refractory is a basic material in the field of high temperature technology. Generally, the refractory is used as structural material or lining to resist high temperature in various thermal equipment and high temperature container. In the iron and steel industry and metallurgy industry, coke ovens are mainly composed of refractory materials. Various refractories that meet the requirements are essential in blast furnace for ironmaking, hot stove, all kinds of steel-making furnaces, soaking furnace and heating furnace. Not only the die casting for molten steel needs lots of refractory materials, but also the continuous casting needs some high-quality refractory materials. Without high-quality refractory materials, external refining is also not impossible to achieve. Statistics show that the steel industry is the sector that needs the most refractory. Pyrometallurgy and thermal processing of ferrous metal also needs refractories. All high-temperature furnaces or lining in construction materials industry or other high temperature industries that produce silicate products such as glass industry, cement industry, and ceramics industry must be constructed with refractory materials. All kinds of roasting funaces, sintering funaces, heating furnaces, boilers, flues, chimneys and protective layers in chemical, power and machinery manufacturing industry need refractories. In short, when some kind of structures, devices, equipments or vessels are used under high temperature, they all should utilize refractory to resist the high temperature because those materials will deform, soften and fuse or will be eroded, scoured or broken due to the physical, chemical, mechanical effects, which may stop the operation, affect the production, contaminate processed objects and impact the quality of products.

Q:What is the most reasonable drying heating curve of magnesia refractories? Products of less than 0.5T: You'd better oxidize magnesia preformed unit at room temperature for a longer period of time, then bake it, during which, it's enough to control the maximum temperature within 300 degrees. During the middle process, usually heating up for 4 hours and keep warm for 3 hours. The entire heating up process takes about 20 hours. If it is the site operation magnesia-based castable, it should be heated slowly in the early stage, and pay attention to keeping warm at 80 degrees Celsius. Every manufacturers has their own heating curves, so do not blindly adopt existing curves, try to make your own heating curve.

Q:Does anyone know what is the use of waste refractory materials?: Waste refractory materials can be 1, Recycled to do the aggregate and powder of castable , or make bricks. 2, can be reused after smash.3, Metal silicon is an anti oxidant in refractory material, mainly functioning as he oxidation resistance, at the same time improve its toughness.

Q:Who knows about the types of Dalian thermal insulating and refractory materials?: There are many Dalian thermal insulation materials, which can be divided into organic and inorganic thermal insulation materials. Materials include inorganic thermal insulation materials, polyfoam, mineral wool products, foam glass, expanded perlite insulation products, gelatine powder EPS grain heat insulating slurry, sprayed mineral wool, thermal insulation product of foam cements, and vacuum thermal insulation board.

Q:The following statement is correct: artificial corundum has a high melting point and can be used as a high grade refractory material. The main component is silica dioxide: 1. corundum is the main component of alumina. 2. agate is the main component of silica. 3. is right. 4. glass is silicate. 5. solar cells are made from monocrystalline silicon. So 3.5 correct, choose D.
