- Q: Why can aluminium hydroxide not be used to make refractory material?
- Hope my answer is helpful to you. It decomposes and produces aluminium oxide and water after heating, chemical equation for the reaction is: 2Al(OH)3=△=Al2O3+3H2O. Aluminium hydroxide can't be directly used to make refractory material because aluminium hydroxide is not stable.
- Q: What are unshaped fire-resisitance materials?
- Refractory castable, refractory plastic material, usually classified according to construction and manufacture method, unfired bricks precast block, refractory pressed into material, refractory cast material, refractory coating, refractory ramming material there are many classification methods
- Q: What's the maximum temperature that the high-temperature resistant refractory ceramic fiber cotton can endure?
- It depends on what material the ceramic fiber gasket uses. It’s usually referred to high temperature gasket made from ceramic fiber paper. It is generally classified into normalized form and high alumina type, of which the former can resist the maximum temperature of 1260℃ and its continuous use temperature is 1000℃, and the latter can be used for a long period at the temperature of 1200℃. 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: It has 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.
- Q: Urgent question: could you tell me that the export of refractory materials to Vietnam is to be packed in wooden cases and smoked?
- Strictly speaking, as long as there are solid wood packaging, you need to do fumigation inspection, proved not necessarily used, there are IPPC chapters on it.
- Q: Urgently!! Refractory problems, online, etc.
- Uneven contraction. When the magnesia block wall is made, the steel wire mesh can be added to the magnesium block wall. That will solve the problem.
- Q: What are the features of construction class A fire resistant door ?
- 1, Save space and reduce cost. Feature of Nanjing Cathay Class A external wall thermal insulation materials : the thickness is between 60mm--180mm, so compared with the traditional block thickness, it saves architectural space greatly. At the same time, the weight is only 1/10 of that of the traditional wall, thus reducing coast in terms of architectural?structure. 2, Fireproof and green. Features of Nanjing Cathay class A fireproof external wall thermal insulation materials: fire endurance under high temperature of 1000℃ is 4 hours, and non-combustible performance can reach state A level, without any toxic gas in full compliance with international environmental standards. 3, Waterproof. Features of Nanjing Cathay Class A fireproof external wall thermal insulation materials: no slightest leakage when it is being used in containers for water without any waterproof finishing. It can be used in kitchens, bathrooms, basements and other wet areas. 4, Sound insulation. Features of Nanjing Cathay class A fireproof external wall thermal insulation materials: internal materials and EPS polystyrene foam granule have good properties of sound insulation and sound absorption. 90mm-thick wall can insulate 40dB sound, in line with national standard of sound insulation for residential building. 5, Thermal insulation. Features of Nanjing Cathay Class A fireproof external wall thermal insulation materials: main raw material is frezing resistant and thermal insulating material which is environmentally friendly and energy saving. With good effect of thermal insulation, it can keep indoor temperature at a constant level, so as to make the environment more comfortable.
- Q: What is special refractories?
- Long nozzle, slidding plate, tapping hole, stopper rods, and products that steel mills use
- Q: Which brand of AAA refractory is good?
- Foshan Nanhai Yanbu Shuying fire-resistant insulation material is very good, and it is a professional company of the production and sale of refractories. Our company specializes in the production of refractory bricks, refractory bricks, refractory castable, refractory aggregate, refractory materials, bauxite, alumina bricks and to undertake the production of various common refractory bricks and non-sizing bricks. The Zhengzhou Fire High Temperature Materials Co., Ltd. is also a good company. It is a collection of R & D and production company. The company mainly produces refractories, refractory bricks, refractory castable, refractory aggregate, refractory materials, special refractory bricks.
- Q: The performance of refractory material
- As for easticity modulus, you can serach for information on the Internet or specialized books.
- 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.
