- Q: Are fire materials poisonous after burning?
- Refractories burning after the smell of toxic, gases are generally silica, alumina, sulfur oxides and so onRefractory material is not less than 1580 degrees of refractoriness, better thermal shock resistance and chemical erosion, low thermal conductivity and low expansion coefficient of non-metallic materials. Acid refractory with silicon oxide as the main component, are commonly used in brick and clay brick. Silica is silica containing more than 94% silica products, raw materials used in silica, silica and other waste, the acid resistance of slag erosion ability, high load softening temperature, volume shrinkage after repeated burning, or even a slight expansion; but it is vulnerable to the erosion of basic slag, thermal shock resistance is poor. The brick is mainly used for thermal equipment of glass furnace, coke oven, acid furnace etc.. Clay brick with refractory clay as the main raw material, containing 30% to 46% of alumina, weak acid refractory material, refractory material, good heat shock resistance, resistance to acid slag, widely used.
- 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: How to calculate the thickness of choosing refractory? Such as steel ladle should choose what kind of refractory and using what thicknes?
- I feel the concrete thickness should depend on the experience and the actual situation. As for the specific method, I also can't say too accurately. If it's ladle, it generally chooses alumina magnesia castable.
- Q: In entering fire door, which material does well?
- Cold rolled steel, or after a flame retardant willow eucalyptus wood, filled up with perlite inside! Fireproof heat insulation. Price is between 300-900, depending on what technology it uses! Company's large-area substrate door (paint) is cheap door, in commonly 350. Followed is without lacquer, which has a layer of decorative materials, generally between 380-500. Finally there is high-grade, which price is around $900. 0...
- Q: whether the fire resistant level of aerated concrete building blocks can reach the grade one?
- the fire resistant level of aerated concrete building blocks can reach the grade one level. Aerated concrete strength grade shall be divided according to the concrete cubic compressive strength value. Use the symbol C and the cube compressive strength value (in N / mm2 or MPa gauge) to express. According to GB50010-2002 "concrete structure design specifications" provisions, ordinary concrete is divided into fourteen levels, namely: C15, C20, C25, C30, C35, C40, C45, C50, C55, C60, C65, C70, C75, C80 .
- Q: What's the fire endurance of hollow brick?
- For hollow brick wall, it should be noted that outside are 200-thick coal gangue hollow brick wall on interior wall. Besides, the fire endurance should comform to GB50067-97 Fireproof code for garage, repair garage, parking lot design. 3), All joints of brick walls and concrete wall column should reserve rebar tie. Masonry mortar in internal and external walls should be full. Wall masonry should be up to bottom of beam slab and filled tightly with 1:3 cement mortar.
- Q: What are the application of old refractory bricks?
- It can still be used as refractory bricks or refractory. The quality of auxiliary material is not as good as bauxite.
- Q: What kind of foundry ingot refractory materials are there? Please be more detailed.
- Classification of refractory materials used in foundry smelting process: refractory brick, siliceous brick, high alumina brick, corundum brick, magnesia brick, magnesia brick, magnesia carbon brick. Unshaped refractory materials: ramming material, castable, refractory cement, silica, magnesia, etc.
- Q: What is fire retardant coating mainly used for?
- Fire retardant coating is a coating which is applied to the surface of buildings and structures and can form a protective layer of fire retardancy and thermal insulation. It can reduce the flammability of the coated materials and block the rapid spread of fire so as to improve fire endurance of the coated materials. Features of fire retardant coating: (1) Fire retardant coating itself has a flame-retardancy or non-inflammability, and it can prevent the protected substrate from direct contact with the air, and delay ignition and reduce the burning speed of the objects. (2) In addition to flame retardancy or non-inflammability, the fire retardant coating itself has a a low thermal conductivity, which can delay the transfer of flame temperature to the substrate to be protected. (3) When heating, fire retardant coating decomposes non-combustible inert gas to dilute the combustible gas decomposed by the protected, making it difficult to burn or slow down the burning rate. (4) Fire retardant coating containing nitrogen will decomposite NO, NH3 and other basic groups, which compound with the organic radicals and interrupt the chain reaction so as to reduce the temperature. (5) intumescent fire retardant coating will expand and foam when heating, and form a carbon foam insulation to block the protected objects, thus delaying the transmission of heat to the substrate.
