ITC glass fiber magnesium oxychloride cement ventilation ducts allowing you to buy value for money

Glass fiber magnesium oxychloride cement ventilation ducts Shandong air conditioning and ventilation equipment - glass fiber magnesium oxychloride cement ventilation ducts (third generation modified Magnesite ventilation pipe, also known as non-combustible inorganic glass steel ventilation ducts), is my company and the Shandong Building Science joint research and development - the kind of new environmentally friendly ventilation ducts `its use can be divided into Class A and Class P D. P class duct mainly used in public buildings, defense engineering and general ventilation and air conditioning needs to be installed in industrial plants and mines and other ventilation pipes, smoke control tube; D class is mainly used in ventilation duct residential buildings, exhaust fumes duct. Glass fiber magnesium oxychloride cement ventilation pipe I produced the modified Magnesite glue as cementing material, glass fiber cloth as a reinforcing material. Modification of the project through the implementation of complex technology, and through a certain process measures to solve the domestic general Magnesite ventilation ducts hygroscopic, back to halogen, deformation, strength, low water resistance is poor, late embrittlement serious ills. While addressing the galvanized iron pipe corrosion poor ventilation, noise; plexiglass steel ventilation ducts flammable, easy deformation; fiberglass duct low intensity, easy deformation shortcomings. By the production and application results show: the performance indicators are reached or exceeded JC646-1996 targets "glass fiber magnesium oxychloride cement ventilation ducts" under, get a good effect, is the alternative to steel and galvanized iron sheet of plexiglass Ventilation ducts varieties preferred products: The product has now been Chinese Magnesite Industry Association as the industry quality products. The main technical parameters of performance a good water resistance, does not absorb moisture, not back to the brine product has been modified to soften the water absorption coefficient of 0.85 or more to hit below 5% greatly improve the water resistance, moisture absorption phenomenon back to halogen products do not exist. 2 high strength, good toughness agent, no deformation of the product after adding reinforcing, toughening agents and other modifiers' its strength, toughness is greatly improved. The main raw material 3 good corrosion resistance of glass fiber magnesium oxychloride cement ventilation ducts magnesium oxide and magnesium chloride solution as' added alkali glass fiber cloth, LM-1 modifier and a variety of other additives made. Acid has good corrosion resistance, completely overcome the shortcomings of metal duct is easy to rust, to cut down a lot of galvanized steel. 4 insulation effect: the thermal conductivity of glass and steel is low, only the metal of 1% -1 ‰. `It is an excellent insulation material insulation properties. Insulation inorganic glass steel ventilation ducts, interlayer insulation performance excellent selection of polystyrene board as an interlayer, insulation and pipe because one, so completely overcome the traditional steel duct plus heat, plus two glass steps, plus two fireproof paint and Thermal insulation materials caused by the gap between tracks and wind, thus greatly reducing the thermal conductivity of the entire air duct (see table below). The product with the traditional metal duct reduced compared with thermal heat transfer coefficient of 38% to achieve a good insulation effect. Thickness 5 small fiberglass ductwork noise than metal duct thick, and itself has a good noise performance at both ends flange, screw connection, in similar vibration muffling effect of magnesium oxychloride cement products in the best its low noise. 6 waterproof performance good waterproof material by the National Testing Center of the duct is non-combustible air duct, the fire index is much better than national standards and national standards, to Class A incombustible fireproof material requirements, see the National Fire departments test report and next Table: 7 craft superior performance glass fiber magnesium oxychloride cement ventilation ducts' may be based on the load, the duct structure, geometry and size requirements for production. It can be made into a variety of complex wind rectangular, square, round, three, Stone, elbow, adjustable pipes and other pipes, and are integrally molded product `stable performance, simple molding process, save time. 8 long service life of the product is made of corrosion-resistant materials are lines, bending, frost, moisture and other fine materials. And it is integrally formed in the production, enhance the quality of the overall structure of the 'thereby greatly extending the life of the air duct. 9 because of the low amount of air leakage in the production of products using the overall shape of the way, the choice of ends and rubber, inorganic material flanged `overcome the tin duct, fiberglass duct shortcomings repeatedly made by the sheet metal processing, greatly reducing the the amount of air leakage and duct resistance losses in the domestic similar products in the minimum amount of air leakage and pressure loss.
