- Q: What's the maximum temperature that the high-temperature resistant refractory ceramic fiber cotton can endure?
- Nichrome wire, stainless steel wire and glass fiber are reinforced. Ceramic fiber coating cloth and slag cloth, sintering ceramic fiber cloth and ceramic fiber fumigation cloth) Characteristics of the ceramic fiber cloth: high temperature resistance, low heat conductivity, thermal shock resistance, low thermal capacity; superior insulating property at high temperature, long service life; resistance to nonferrous metals like molten aluminum and zinc erosion; low and high temperature strength; innocuity with no adverse effect on the environment; Applications of ceramic fiber cloth: It can be applied to the thermal insulation of all kinds of furnaces, high-temperature pipelines and vessels; furnace doors, valves, flange seal, fire doors, fire resisting shutters and high-temperature furnace door curtains; engine and instrument insulation, clad material of fireproof cables, and high-temperature resistant and fire-proof materials; thermal insulation cloth for coverage, high-temperature expansion gap padding, and inner linings of the flue; high temperature resistant labor safety products, fireproof suits, high-temperature filtration and sound absorption, replacement of asbestos, etc.
- Q: Which brand of thermal insulating refractory is good?
- The most famous is the dragon, Morgan, Luyang, which are good at making ordinary thermal insulation materials and whose products are cheap but quality. Refractories are non-metallic materials with good resistance against thermal shock and chemical erosion, low heat conductivity coefficient and expansion coefficient. It requires high temperature resistance in nature. It is difficult to transport suc materials in silicious thermal insulation board production base. Silicious thermal insulation board is a kind of thermal insulation material during casting process. Raw materials are non-porous refractory?aggregate, porous refractory?aggregate, organic fiber and inorganic fiber.
- Q: What characteristics do A grade external wall fireproofing material have?
- For characteristics of A grade external wall fireproofing material, its main raw material uses cold resistant and thermal insulated, environmental protection and energy saving material with good insulation, keeping the indoor temperature steady and making the environment more comfortable. It is several times better than other masonry in overall strength and resist capability, and it can also hang heavy objects such as air conditioners by directly nailing or installing expansion bolts. Single point hanging machine can withstand heavy objects with the weight of more than 45kg. It can also be directly fixed to the tiles, wallpaper, wooden plaques, paint, etc.
- Q: How long is the fire endurance of Grade A fire resisting shutter
- The fire endurance of Grade A fire resisting shutter is not lower than 1.20h. Use fire resisting shutter as fire?compartment separation in places where it is difficult to set firewall. When fire resisting shutter whose unexposed surface temperature rise is used as judging condition of fire endurance is used, its fire endurance should not be lower than 3h. When fire resisting shutter whose unexposed surface temperature rise is used as judging condition of fire endurance is not used, individual protection of ?closed automatic water spray system shoule be set at two sides of the shutters and duration of water spray system should not be less than 3.0h.
- Q: What kind of refractory materials can withstand 1500℃ when processing briquette stove core and meanwhile cost less?
- Alkali resistant castables cost the least.
- Q: What are the main components of refractory cement?
- SiO powder is often used. Ultra-fine powder refers to less than 1 / zm particles which are made by hydrolysis of ethyl silicate or made from recycled dust in the smelting process of ferro-silicon alloy. Non-cement castable refractory are castable refractory material which contains no cement instead it relies on the coagulation and combination by adding ultra-fine powder or sol (see refractory castable), and it is an amorphous material with high activity. Silica sol is made through Ion-exchange of sodium silicate after Na ions are removed. The easiest method is to prepare by reaction of aluminum metal with hydrochloric acid or alchlor. It is a thermodynamically unstable system which has certain requirements for ultra-fine powder and sol. It is different from non-cement refractory castable, Cr2zrOz and etc. It has low impurity content, and can bond with itself, so it has good binding strength. Ultrafine powder used in non-cement castables are SiO2, Al2O3, Cr2zrOz, etc. Such recycled SiO2 powder has an average particle diameter of 0.5 pm, therefore when adding the gelling agent (electrolyte), it can coagulate and give the products some bonding strength. Non-cement castable refractory is made up of refractory aggregate and powder and it is round. Since the use of superfine powder or sol as binder. The size of sol particles are of 0.1 ~ 1 m. 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. There are several ways to prepare alumina sol. The sol used are mainly alumina oxide and silica sol. The surface area is large, and it helps to improve high-temperature structural strength. Non-cement castable refractories rely on oxide ultra-fine powder or sol to coagulate and combinate. It is a refractory castable (also known as chemical bonding castable) which uses chemical binder instead of cement for combination.
- Q: Can polystyrene foam color steel plate be used as decorative fireproofing material ?
- Polystyrene foam plastic can not be used as fireproofing material; polystyrene foam plastic is made up of polystyrene resin as main component, foaming?agent and other additives. It is a buffer material which is most widely used[1]. It is closed hole structure, so it has low water-absorbing quality and excellent water resistance; low density, about 0.015 ~0.03; good mechanical strength, excellent buffer?performance; good machinability, easy to be moulded; good dyeing property, thermal adaptability and anti-radiation; high dimensional accuracy, uniform structure. Therefore, it has a large share in external wall thermal insulation. But it will emit polluted styrene gas when burning. It is a kind of class B material in construction.
- Q: What 's the highest temperature can magnesium plate glass resist ?
- You just need a fire-resistance board thicker than 10 mm ,remember to add more perlite as filler during production , 12 mm plate is 80 yuan.
- Q: what textures of furnace refractories are good?
- First, it depends on the kiln. If it is the cubic kiln, the top and the wall portion should use alumina hollow ball bricks. The bent seal and kiln car use heavy corundum bricks. If it is the consecutive kiln, the burning zone shall all use the alumina hollow ball bricks, and both the burning zone bent seal and the brick kiln car bent seal use the heavy corundum bricks. Ifit is the pit furnace, furnace walls and roof use the alumina hollow ball bricks, and the bottom of the furnace use heavy corundum bricks.
- Q: What's the A grade fireproofing material?
- A grade fireproofing material: 1. fire-proof plate; 2. fireproof wooden door; 3. fireproof wooden window frame; 4. fire resisting shutter; 5. fireproof and mothproof wood; 6. fireproof glove compartment; 8. fire?retardant?coating; 9. fire-proof?sealing?material.
