Inorganic microporous magnesium crystalline silicon plate/magnesium plate - industrial integrated assembled smoke exhaust duct
The prefabricated finished smoke exhaust duct has excellent fire resistance and insulation performance. The superior characteristics of high strength, low thermal conductivity, good sound insulation performance, and long service life have been widely used in various fields of smoke control and exhaust. It is suitable for smoke control and exhaust systems with fire resistance, corrosion resistance, good pressure resistance, thermal insulation, sound insulation, silence, cleanliness, and moisture resistance requirements.
The internal and external surfaces of prefabricated finished smoke exhaust ducts are made of metal materials, and the middle layer is an inorganic refractory layer and a fireproof insulation layer. Its comprehensive performance is excellent, beautiful, and durable, especially in terms of mechanical properties such as bending resistance, compression resistance, brittleness, and processing performance, which can meet the requirements of high-level and high requirements for smoke exhaust ducts; When making smoke exhaust ducts, the commonly used color steel plate surface is on the outer side of the inorganic refractory layer, and the galvanized steel plate surface is on the inner side of the fire insulation layer pipe. It is processed according to the required shape, specifications, and dimensions. According to the usage situation or connection process requirements, angle steel metal flanges can be selected to make assembled fire-resistant ducts, which are suitable for the requirements of the "Fire Resistance Test Method for Ventilation Ducts" (GB17428-2009) in the new standard GB51251-2017, The installation engineering of a system with a fire resistance limit that meets the integrity and insulation of smoke exhaust ducts.
