- Q:What are the components of refractory clay?
- It is different from non-cement castable refractories, which does not rely on the addition of cement for combination, instead it uses chemical binder. It is refractory castable (also known as chemical bonding castable). Non-cement refractory castable takes oxide or synthetic compound ultra-fine powder or oxide sol-gel which is similar to the chemical composition of material in tungsten castable. Since the use of superfine powder or sol as binder, it has low impurity content, and therefore the refractoriness and slag erosion resistance of the castable will not be reduced. Besides, the self combination in use can help to improve high-temperature structural strength. Non-cement castable refractory is made up of refractory aggregate and powder, superfine powder of oxide or sol, trace amount of dispergator (or anti-coagulant) and proper slow acting hardener. Non-cement castable is mainly coagulated and combinated by ultrafine powder of oxide or sol, therefore, it has certain requirements for ultrafine and sol. Ultrafine powder used refers to less than 1 / zm particles. Ultrafine powder used in non-cement castables are SiO2, Al2O3, Cr2zrOz, etc. SiO micro powder is often adopted, which is the dust recycled during the smelting of metallic silicon, ferro-silicon alloy, the generation process is as follows: This recycled SiO2 powder has an average particle diameter of 0.5 pM, and it is spherical with large surface area. It is amorphous substance with high activity, so it has good bonding strength. The sol used are mainly alumina oxide and silica sol. Silica sol is made by ion exchange of sodium silicate after Na ions are removed. It can also be made after hydrolysis of ethyl silicate. There are several ways of preparing alumina sol, the easiest method is to prepare by the reaction of metallic aluminum or alchlor with hydrochloric acid.
- Q:who knows the fire resistant levels of fireproofing glass?
- According to the fire resistance levels, it can be divided into three categories: Class A: a kind of fireproofing glass that can satisfy the requirements of refractory integrity, refractory and thermal insulation at the same time. Including composite flameproof?glass and perfusion type fireproofing glass . This kind of glass has the properiyies of transmittance, fireproofing ( smoke insulation, fireproofing, and keeping out thermal radiation), sound insulation, shock resistance, and it's suitable for steel and wooden fire door of building decoration, windows, varnishing, partition walldaylighting?roof,ceiling?screen,perspective floor and other construction components demading for transparency and fireproofing. Class B: Marine fireproofing glass, including porthole fireproofing glass and rectangular window fireproofing glass, surface glass pane is tempered safety glass, the inner surface glass pane material can be arbitrary selection. Class C: it's a kind of monolithic fireproofing glass that only satisfies the requirements of refractory integrity. This kind of glass has characteristics of transmittance, fireproofing, smoke insulation and high strength,etc. It's suitable for fireproofing glass partition wall, fire Windows, outside curtain wall and other places without insulation requirements.
- Q:What is the appropiate thickness if fire resistant time for ultra thin steel structure coating is 2.5 hours?
- Hello steel structure can adopt surrounding concrete or brick, fireproof coating, fireproof board coating and composite structure for its fire resisitance. Fire resisitance board can be divided into thick fire protection plate and thin plate, the thickness of the plate thickness of the fire is between 20 ~ 50mm, mainly includes calcium silicate fireproof board and expansion boring stone fire board, the main varieties are KB board, CF; thin fireproof plate is between 6 ~ 15mm thick, the main varieties include enforced short fiber cement plate, ordinary enforced fiber silicate calcium board and glass cloth reinforced inorganic board.
- Q:What's the material of electrical fire prevention board?
- Industrial 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! ! ! !
- Q:How many types of special refractories are there?
- Metal ceramics, high temperature coatings, high temperature fiber and other reinforced materials
- Q:Can anyone say something about the curtain wall fire-proof material key sealing point?
- When sealing the gaps between glass?curtain?wall and floors of all layers and the outer edge of the partition with rock wool or mineral wool, its thickness should not be less than 100mm and should be filled densely; Rock wool or mineral wool for horizontal smoke prevention zone between floors should use galvanized steel sheet whose thickness is not less than 1.5mm to support; The gaps between supporting plate, major structure, curtain wall structure and supporting plate should be filled with fire-resistant glass, whose fire endurance should meet the design requirements. Fire-resistant glass for curtain wall are mainly include monolithic fire-resistant glass as well as the hollow glass and laminated glass made by monolithic fire-resistant glass.
- Q:What are the new refractories?
- Sintering zirconite. I produce the refractory in Zibo.
- Q:What are the refractories for converter?
- Analysis of refractories are as follows: MgO-C brick converter Dongxin refractory furnace cap, steel tapping hole, shaft, shaft, pool, air brick
- Q:How many kilns using refractories are needed? What are the furnaces respectively?
- Kiln and five hundred-degree centigrade thermal equipment need to use refractories, glass furnaces, electric arc furnaces, mixer, cement rotary kiln, open hearth furnace and limestone kiln; in fact, when the temperature is more than four, the mesh belt furnace, blast furnace, cupola oven, stove, pushing plate kiln, furnace, heat treatment furnace, roller kiln, down draft kiln, ladle, coke, shuttle kiln,etc.
- Q:What are the material requirements of class A fire resistant door ?
- What are the material requirements of class A fire resistant door ?
