Description
Technical field
The present invention relates to a kind of glass composite air duct fabrication and installation technique, belong to technical field of building construction.
Background technology
Glass fiber composite air duct is in order to be applicable new technology, new material and a kind of novel wind tube developed, with ultra-fine fibre
Based on plate, it is combined through special processing.Collect insulation, noise elimination, damp-proof and fireproof, anti-corrosion, (being adapted to bright dress) outer layer intensity attractive in appearance
The multiple function such as height, internal layer surface antimildew and antibacterial has in light weight in one, and inleakage is small, fabrication and installation are fast, space-consuming
It is small, divulge information, the advantages that performance and price is more reasonable.Especially its excellent insulation and acoustic attenuation performance are had a preference for by users.
Compared with traditional handicraft airduct, it can also be that user saves pipe-line system investment 20% or so.
Glass fiber composite air duct composite glass wool board cuts through cutter, bonded, sealant tape sealing and reinforcing form.It is multiple
The double sheaths for closing block of glass wool are glass fabric clad aluminum foil or sheath is block of glass wool.Block of glass wool uses centrifugal process shape
Into glass fibre add resin glue through hot pressing, curing molding.The conventional lattice of plate：70~75kg of density m2, thickness 25mm.Due to
Composite glass wool board interlayer is porous light-weight material, thermal conductivity factor is low, and acoustic absorptivity is big, thus glass composite air duct has well
Insulation and acoustic attenuation performance；Meanwhile airduct have material light, short construction period, fire prevention, protection against the tide, without unwanted volatile, beautiful outline form
The features such as sight, service life length, low cost.Compared with composite glassfibre air duct adds insulation with galvanized steel plain sheet airduct, engineering cost can be saved
With more than 30%, do not include the field device expense that disappears saved still, be low, middle pressure air conditioner ventilating system is the most economical, be applicable one
Kind ventilation shaft.
