$Dry Impermeable Refractory Material$

Q:what is the fireproofing material of engine room? who knows it ?: machine room fireproofing materials include: Inorganic binder: The main material includes sodium silicate, gypsum, phosphates, cement,ect.; refractory mineral filler: aluminium oxide, asbestos powder, calcium carbonate, perlite, cornstarch, ect.; nonflammable organic resin: it mainly includes polyvinyl chloride, perchloro-ethylene, chlorinated rubber, neoprene latex, epoxy resin, phenol resin, ect.. nonflammable fireproof addictive: it mainly has phosphorus, halogens, nitrogen organic compounds (chlorinated paraffins, tributyl phosphate,deca-brominated diphenyl ether), and boron series (boric acid, zinc borate, aluminium borate), antimony system, aluminium series, zirconium system, etc. inorganic compounds.

Q:What kind of materials are needed to make refractory bricks?: Refractory materials generally refer to inorganic non-metallic materials with fire resistance above 1580℃. It plays an important role in metallurgy, nonferrous metals, chemical engineering, ceramics, and industrial production. Different industry needs different materials. You can turn to the knowledgeable internet.

Q:What material is used to make furnace pipe of refractory bricks?: Refractory bricks furnace pipe material is generally divided into two types, namely, shapeless refractory material and shaped refractory. Shapeless refractory material, also known as castable refractory, is hybrid powder material made up of many kinds of aggregate or aggregate and a kind of or many kinds of binders. It must cooperate and evenly stir with a kind or many kinds of liquids during use and has strong mobility. Shaped refractory material usually refers to refractory brick whose shape has standard rules. It can also be proceeded temporarily during cutting according to requirement.

Q:What refractory materials are used in power plant: Vacuum mud machine, sintering furnace! And then I will introduce some application of thermal material in power plant (below) I hope I can help you. Energy saving is the trend of future industrial development efforts, grinding machine, conveyor belt, so the production of light thermal insulation materials will gain state support, drying kiln. Our factory mainly produce light thermal insulation brick. The refractory material we use most is light insulation brick, and the equipment used is sand mixer (Luohe, Henan)

Q:What's the refractory material in common use currently?: (1) Alumina-silica refractory brick: Except the transition band, hot end and firing zone of the rotatory cement kiln, it can be applied to the whole burning system of the precalcining kiln, such as the fixed wall lining, wicket, cooling machine, tertiary air duct, burner, etc. It mainly includes alkali-resisting brick, high alumina (anti stripping) brick, silica-mullite brick, etc. (2) Basic refractory: For the upper transition band close to the part of burning zone and the burning zone, its inner lining can endure the highest flame temperature of 2000℃ and material temperature of 1350℃-1400℃, and it also has to withstand the permeation of sulfur and alkali compounds, permeation, thermal shock and oxidoreduction of hot-melt clinkers (liquid phase), mechanical stress of elliptic cylinder deformation, etc. Therefore, inner linings are the most demanding parts to withstand stress, and only basic refractory can meet with requirements under this working condition. (3) Fireclay insulating refractory: Its microstructure has notable characteristics of high porosity, large pore size and thermal insulation performance. For its low volume density and light weight, it is usually referred to as lightweight refractory. Fireclay insulating refractory product has great varieties, and it is usually classified and named according to its chemical and mineral compositions or production raw materials, and it is also classified according to its operating temperature and material form. Currently, the most used main thermal insulation material for the precalciner kiln system at home and abroad is calcium silicate board; besides, light weight castable and insulating fire brick are increasingly used year by year. Other thermal insulation materials are mainly ceramic fiber products.

Q:what is the material of fixed first rate fire resistant window?: Window frames and fireproofing glass, fire sealing strip, fireproofing glass mound layer, which is infexible fan, and the flexible fans have to plus folding and closing window cleaner. (3) window frames must be integral with the building, using wood or iron to connect the wall. After the installation of the steel frame, the cement mortar must be watered between the window frame and the wall, and it should conserve more than 24 hours before normal use.

Q:what is the requirements of roofing insulation materials fire rating?: The fireproofing requirements of architectural design are regulated by architectural design fire?safety?rules, roofing insulation material only has the requirements of materials combustion performance, namely non-combustible material. No fire rating requirements.

Q:How long is the duration of fire resistance of autoclaved flyash-lime bricks?: The compressive strength of the autoclaved flyash-lime bricks is generally higher, which can reach 20MPa or 15MPa, at least 10MPa, and it can withstand the 15 freeze-thaw cycles. Besides,fly ash brick is a kind of potential active hydraulic material. In the humid environment, it can continue to produce hydration reaction and make the internal structure of the brick is more dense, which is conducive to improvement of the strength. It is found in experiments and many investigations that sample some carbide which is used for foundation, plinth and drains, after one or twenty years of freezing thawing and wetting drying, some bricks have been completely carbonized, but strength is not reduced, increased instead. This is one of the merit of autoclaved flyash-lime bricks.

Q:Urgent question: could you tell me that the export of refractory materials to Vietnam is to be packed in wooden cases and smoked?: If the outer packing is made of solid wood, it must be fumigated! If it is not solid wood, you can do without!

Q:which kind of material should be used in fireproofing cabinet?: Here are a few good materials: 1. The mineral wool board, glass wool board: it mainly tales mineral wool, glass wool as insulation materials. It's non-combustible, light weight and has good high temperature resistance, but there are shortcomings ① short?fiber will harm the human respiratory system, ② poor sheet strength, ③ poor barrier property of sheet for smoke of fire disaster, ④ poor decorative properity, ⑤large installment and construction work. Thus, most of the boards were sheets that take inorganic anchoring material as base material, glass wool as reinforcing material. 2. cement board: Cement board has high strength and wide sources. It is often used in fireproof suspended?ceiling and partition in the past, but it has poor fire resistance and is easy to burst and lose protective function , which will limit it's applications. Cement concrete component has good thermal insulation and sound insulation properties, and it can be used as partition and roof board. Fiber reinforced cement board and other improved varieties appear in the construction?materials market, and they are high strength and have good fire resistance, but their disadvantages are poor toughness, large alkalinity and poor decoration effect. 3. perlite board, cenosphere board, vermiculite board: It's a kind of hollow plate that takes low alkalinity cement as base material, perlite, glass beads, vermiculite as the aerated filling material, and is made by adding some auxiliary. It has characteristics of light weight, high strength, good toughness, fireproofing and thermal insulation, easy for construction,etc. and it can be widely used in high-rise building frame compartment, household, bathroom, kitchen, communication pipe and other non-load bearing areas.
