Promise glass steel prices Introduction inorganic fiberglass duct is handmade, one-time molding, duct thickness may be uneven place. Duct can also be made into a double insulation type, usually the default insulation thickness 20mm, it can also be customized according to customer needs. Inorganic fiberglass duct into their performance cementitious materials: sulphate class made cementitious materials and glass fiber mesh of the hydraulic inorganic fiberglass duct and the modified magnesium oxychloride cement as cementing material with the glass Two types of cement pipe wind rigid gas modified magnesium oxychloride fiber mesh made. BINDER body PH value should be less than 8.8, it does not respond fiberglass alkaline corrosion. Inorganic glass steel duct should be used alkali, alkali or alkali-resistant fiberglass mesh, and were consistent with current national standards "fiberglass mesh" JC561, "E-glass fiber, woven roving" JC / T281, Regulations "alkali fiberglass roving" JC / T576's. Quality MOC duct magnesium oxide should comply with national standards, "with a light burning magnesium products magnesia" provides WB / T1019-2002 of. Inorganic glass steel duct into the overall general (non-insulation), the overall insulation type (internal and external surfaces of inorganic glass, the middle insulating material), combination (from a composite plate, special glue, flanges, reinforcing corner pieces and other connections rampant tube) and a combination of four types of insulation type, its production parameters specified in Table 1, 2, 3. Vertical fiberglass mesh between adjacent layers, the distance should be greater than the cross lap joint 300mm, with layer lap joint distance of not less than 500mm. Lap length should be greater than 50mm.
