Q:What's the material of electrical fire prevention board?
Electrical fire prevention board uses the material of inorganic binders, which mainly includes water glass, gypsum, phosphate, and cement; refractory mineral fillers: alumina, asbestos powder, calcium carbonate, perlite, cornstarch and etc.; electrical fire prevention board is mainly aimed at fire protection and thermal insulation. Iron plate is electrically conductive with good thermal conductivity, which will cause the result that the equipment is not insulated and suffers larger superheating surface. Hope my answer is helpful for you.
Q:What material is used for making refractory stone bowl?
Stone pot is carved from high-quality natural refractory stone with a professional way. It has attractive and diverse appearance, and it is hard, heat fast, not stick food. Now it is used in many hot pot restaurants.
Q:What refractories have good mechanical property resistance and heat expansion and cold contraction property?
Explain that where you use it for and what requirements you have. Follow-up: I use it in metallurgical furnaces with the features of strong stirring and acidic residue.
Q:How long is the fire endurance of the rock wool board?
The rock wool board takes the basalt as raw material and is processed into artificial inorganic fiber through high temperature melting, which is light in weight, non-combustible, heat absorptive, small in thermal conductivity. The initial development in construction is a common type of application used for industrial buildings, which should be consistent with the requirements of "building insulation application categories and basic requirements" . In June 1981 the pre-launch succeeds. The rock wool board is a new type of insulation, burning compartment and sound-absorbing material. Generally the fire resistance of the rock wool board is 140-180 degree within two hours, It is best not to exceed this safe period, in order to avoid security risks.
Q:How to prolong the furnace age of Induction furnace by using fireproof materials?
magnesia solid materials have thermal endurance and erosion/ performance and its change of temperature is likely to cause cracks. properties of materials (aluminum) in such case have to be taken into consideration.
Q:What do refractory materials include?
It is so difficult.
Q:What are the material requirements of class A fire resistant door ?
Refractory time should be no less than 1.5 hours.
Q:What are the fire protection standards of insulation materials?
This question is, like this. The combustion performance of thermal insulation materials for exterior walls of all civil buildings, within the scope of fire design auditing and fire control acceptance, should be brought into the auditing and acceptance. As for the "Management Regulations on Supervisions of Fire Prevention and Control for Building Projects" (Ministry of Public Order No. 106) , all civil buildings which are out of the scope of Article 13 and 14 are included in the random check. Before the release of new standard, it must be strictly implemented the Article II of the "Fire prevention Interim Provisions on civil external wall insulation system and external wall decorative" ([2009] No. 46), namely, the insulation materials of civil buildings must use materials with A-level combustion performance.
Q:Who can tell me what is neutral refractory?
It is a material that can resist acidic and basic slag, flux and chemical erosion form other refractories at high temperatures. The main components include carbon, silicon carbide, aluminum oxide, chromium oxide and other trivalent oxides, such as carbon refractories and chrome refractories, etc. Strictly speaking, neutral refractories refer only to the carbonaceous refractories, including carbon brick and graphite silicon carbide products, etc. Sometimes, high alumina refractories with high Al2O3 content also belong to this material, such as some materials that are acidic but tend to be basic refractories, like sillimanite, mullite bricks and corundum bricks. Recently developed aluminum carbon bricks, zirconium carbon bricks alumina - silicon carbide - carbon bricks, silicon nitride bonded silicon carbide brick and so on are also neutral refractories. This material can be used in the bottom of blast furnace, the lining of hearth and bosh, and the lining of aluminum electrolytic cell, calcium carbide furnace, ferroalloy furnace, molten steel ladle, plating tank, reaction tank, and autoclave and so on.
Q:What kind of flexible fireproof material is really good?
The best one is grade A fireproof material. A-class fire flexible material adopts clay, stone, sand, cement blocks and other inorganic powder and modifier and product density is 2327 kg/m3. Upon examination, the combustion performance of this product is in accordance with the grade A specified requirements and additional classification meets A s2, d0, t0 level requirements. According to GB 8624-2006, the combustion performance of product reach A2 - s2, d0, t0 level.
