Q: what grades are fire resistance of fireproofing glass divided into?: Fireproofing glass is a kind of special glass which can keep its integrity and thermal insulation performance in regular insulating refractory trials. and it can be divided into three classes according to its fire resistance: Class A, it's a kind of fireproofing glass that can satisfy the requirements of refractory integrity, refractory and thermal insulation at the same time. 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, it's a kind of fireproofing glass that can satisfy the requirements of refractory integrity, refractory and thermal insulation at the same time. Such kind of fireproofing glasses mostly are composite fireproofing glasses and has characteristics of transmittance,fireproofing and smoke insulation. Class C, it's a kind of 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: Why the refractories should be waterproof and wetproof: It is necessary to like magnesium carbon, waterproof and wetproof is more important. There is a variety of refractory materials, in general, basic is defective, and wherein the binder and additives water will lose their effect, the relationship is not very high aluminum large amount of water determines how much of the performance after the hydration will affect the strength and high temperature performance ;; hydration & quot, just need a little package like magnesium and calcium-based product itself readily react with water to calcium oxide, magnesium, chromium is not all the material goods have waterproof ordinary bulk materials need to add water before use

Q: I know which material is the fire resistance rolling shutter door: the materials of fire resistance rolling shutter door are: the inner of fire resistance rolling shutter door is generally filled with aluminum silicate fiber cotton. fire resistance rolling shutter door is divided into AAA inorganic fireproof rolling shutter door and steel fire resistance rolling shutter door. the fireproof?performance of inorganic fireproof rolling shutter door is better, but steel fire resistance rolling shutter door has a certain wind load resistance, which can be installed outdoors.

Q: What's the definition of fire endurance of the fire-resistant coating for steel structure?: 1. Fire endurance. Conduct fire resistance test of any building component according to the standard time-temperature curve, and the time when it is subjected to the fire to the time when it loses support capability or fire insulation function or its integrality is destroyed is referred to fire endurance. 2. Steel has relatively low fire endurance which is usually 0.25h only, namely 15 minutes; 3. Of steel structure buildings, steel can be used as beams, pillars, etc. but its fire endurance is not enough (usually these components have higher requirement on fire endurance, and take pillar as an example, it is usually demanded that the fire endurance should be 2-3h), and under this condition, it needs to brush fire retardant coating so as to raise the fire endurance. As to the specific quantity or types of the fire retardant coating, it is decided upon the actual conditions. In short, the building material needs to meet the required fire endurance of the buildings.

Q: How to prolong the furnace age of Induction furnace by using fireproof materials?: magnesia solid materials have thermal endurance and erosion/ performance and its change of temperature is likely to cause cracks. properties of materials (aluminum) in such case have to be taken into consideration.

Q: What is the fire endurance of fireproof glass cotton?: Good thermal insulation and thermal insulation. thermal insulation and thermal insulation depends on the heat conductivity coefficient of glass?silk λ=0.043W/m2K. good fireproof?performance, it's fire-resistant capacity is more than 1000 ℃.

Q: What are the differences between intensive refractory busway and other busways?: Compact busway is named according to its structure, and fire-resistant busway is named after its uses. Compact busway especially refers to busway which is closely laminated between phases and between phase and shell, and use thin insulating material to achieve the insulation result. suitable for power supply system of alternating current three-phase four-wire, three-phase five-wire system, frequency of 50 ~ 60Hz, rated voltage up to 690V, rated operational current of 250 ~ 5000A, as auxiliary equipment for mining, enterprises and high-rise buildings, and especially suitable for the transformation of workshop and old enterprises. Fire-resistant busway is composed of shell coated with fire retardant paint, bus line wrapped with fire-resistant mica tape and bracket made by refractory insulating material. Bracket has a plurality of grooves where inbedding the bus line and fixed it. There is a busway connecting box at one end of the busway and there is a bus line splitter box in the busway. Fire-resistant busway has excellent insulation properties, which can not only be used continuously in a normal environment, but also can be used in the fire environment continuously for more than one hour, suitable for high-rise buildings and important facilities, replacing the fire-resistant cables to transmit and distribute power .

Q: How to choose the material of refractory?: Long using temperature of aluminum oxide fiber is 1400 ℃, containing chromium aluminum silicate fiber, quartz, high purity aluminum silicate fiber, long-term use of temperature is 1000-1200 ℃ has aluminum silicate refractory fiber according to different raw materials, advanced refractory fiber (such as alumina. Commonly used vitreous aluminum silicate refractory fibre is amorphous, zirconium oxide refractory fibre) using temperature is 1700 ℃ view as >and the best temperature is 1300 ℃. Crystalline refractory fiber are polycrystalline mullite fiber, including ordinary aluminum silicate fiber, alumina and graphite refractory fiber, etc. The use of common refractory fiber temperature is 1150 ℃;>
