[Tianjin Jinzhong Ji HVAC purification equipment to recommend the star product - Duct Duct] is used for air transport and distribution pipeline system. There are two types of composite pipe and inorganic air duct. Duct cross-sectional shape and material can be classified. Duct production of stainless steel duct production is sewn seams, rivets and joints, flange flange gap at the four corners, etc. Apply sealant (eg neutral glass, plastic). Should remove surface dirt and grease before applying sealant. Press the cross-sectional shape, can be divided into circular duct duct, rectangular duct, oval duct, and other kinds, including circular duct of least resistance, the height of the largest angle iron flange pipe production complex. Therefore, the main application of a rectangular duct. Material, duct can be divided into metal duct, composite duct, polymer duct. [Tianjin Jinzhong Ji HVAC purification equipment to recommend the star product - use complex ventilation ductwork] board machine production of magnesium inorganic composite duct sheet is magnesium oxide, magnesium chloride cementitious material to neutralize the alkaline glass webs of reinforcing material, sawdust, straw for filler composite made of new non-combustible decorative materials made of a special processing. Composite duct board with mechanized production, smooth surface, friction coefficient, low drag and fireproof, waterproof, dustproof, environmental protection, non-toxic, anti-aging, corrosion, smoke pipes, tasteless, shock absorption silencer, insulation insulation, no distortion, no cracks total of flange pipe, does not absorb moisture, good volume stability, simplicity of construction and operation of the advantages of long life.
