Q:What refractories can withstand high temperature above 2100 degrees?
You can refer to advices from the first one coupled with the second one.
Q:What are the new refractories?
Silicon carbide kiln furniture and mullite cordierite kiln furniture. Jing Cheng Refractories Plant in Yanshi City 0379-62222036
Q:Who knows the texture of fire-proof wooden door material?
The so-called fire doors are only posted a layer of fireproof material. Door selection still depends on the timber inside. The simplest way is to see the weight value, fireproof material layer, and they are generally paint-free doors. with fireproofing function..
Q:Do you know what the main indicators are for the inspection of refractory materials? Thank you very much for your requests and reports
Fire resistance, combustion performance, combustion heat value, fire resistance, high temperature resistance, fire rating test and so on. Regular testing institutions are generally reported, Qingdao standard also can, the results are more accurate.
Q:What kind of refractory materials should be used for the intermediate frequency furnace to smelt manganese?
You mean furnace lining or ladle lining? Generally magnesia is used as furnace lining, but heat preservation should be practiced when shut down, or brasque would crack. Surly you can employ existing furnace lining which is sold in Tianjin, a little bit expensive, the average lining could be used for 300 furnaces. The furnaces made by magnesia myself break down after 40 furnace were finished. What I referred is a furnace weighing 2 tons, as for a bigger furnace, the existing brasque would be OK. What is the difference between furnace lining and ladle lining? Can you give me more detail about the materials of making a furnace weighing 2 ton? Why others can burn 80-90 furnace with 0.7-ton furnace; over 200 furnaces with 2 ton? What are these ingredients? What I know is just magnesia, magnesium borate, and together with boric acid, they also have many types, which one should I use? Thank you!
Q:Kinds of refractory mortar
It needs no heating when hardened. There are two kinds of refractory mortar, the finished products and semi-finished products. Clinker is compounded in proportion according to the hardening temperature. (3) Chemical bonding refractory mortar is made from refractory aggregate and chemical binders (inorganic, high alumina refractory mortar). After this refractory mortar with thermal hardness is hardened, it has some contraction. Ther is a wide variety of refractories used on the constrcuction sites: // a, Advanced refractories (1770 ~ 2000 ℃) and AAA level refractories (2000 ℃ above). It can only be delivered in dry state. Air hardening refractory mortar is often compounded air hardening binders such as sodium silicate. It will harden below ceramic bonding temperature. According to different binding agents.
Q:How to divide the fire rating standards of insulation materials?
1. According to the GB8624-97 national standard, building materials can be divided into following levels in terms of combustion performance. A-level: Non-combustible building materials: Materials almost don't burn. B1-level: Fire-retardant building materials: Fire-retardant 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 materials: Combustible building materials can play a certain role in preventing combustion. It will immediately burst into flames when coming across open fire or at high temperature, and will lead to fire spreading, such as wooden pillars, roof frames and beams as well as stairs. B3-level: Inflammable building materials: 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, ceramic foam, foam cement, close-celled perlite, etc. 2. The insulation materials with B1-level combustion performance: specially-treated extruded polystyrene boards(XPS)/ specially-treated Polyurethane(PU), Phenolics, Polystyrene rubber powdery particles,etc. 3. Insulation materials with B2-level combustion performance: Expanded polystyrene sheets(EPS), Extruded polystyrene board(XPS), Polyurethane(PU), Polyethylene(PE), etc.
Q:What are the insulation fireproofing materials?
Asbestos is the most common. Asbestos containing zirconium and made of the mixture of zirconium aluminum and silicon through wire drawing is better. Of course, some are made directly from natural things which can withstand 1400 degrees for over 30 seconds while the internal temperature had no significant change, and withstand 1400 degrees for over five minutes while inside temperature increase does not exceed 5 degrees.
Q:Fire insulation and fireproof insulation board materials What is the difference in performance?
Fireproof materials and insulation materials, refractories not the same thing, but some insulation materials are fire resistant and refractory. Fireproof material is a synthetic material characteristics of fire resistance or the material itself is a high temperature resistant, flame-retardant. Fireproof materials are mostly used for construction, playing an important role in fireproof today in various forms.
Q:Who knows how to divide the building fire grade and fire resistance grade?
I hope to help you building fireproof rank division is one of the most basic measure in building fire safety technical measures, Building's fireproof rank is divided into class one, two, three, four according to China's architectural design specification. Fire-resistant capability of the highest level is the strongest; Fire resistance of four level of the weakest. The fire resistance level of a building depends on the combustion performance and fire resistance of the building components that comprise the building. The so-called building component refers to a series of basic components, such as wall, foundation, beam, column, floor, stair, ceiling and so on. The judgment condition of the fire resistance There are three conditions for components' fire resistance limit to be reached, namely, the fire resistance limit of the building component: Loss of support and integrity; loss of time to fire the role of the time; as long as any of these three conditions is met, it will reach its limit of fire. Hope my answer will help you.
