Abstract
A noise elimination sound insulation high hydrophobic environment-friendly air duct comprises an air duct shell made of galvanized sheet iron. A white environment-friendly formaldehyde-free glass wool insulation layer is lined in the air duct shell made of the galvanized sheet iron and is fixed with the shell in reinforcing mode through welding nails. A surface layer of the formaldehyde-free glass wool insulation layer is made of a polymer nanometer coating and a nanometer antibacterial mouldproof fiberglass mat and is fireproof, high hydrophobic, waterproof, humidity insulating, mouldproof, anti-bacterial, corrosion preventing, glass fiber coming-off preventing, and the like. The air ducts are connected through a common-plate flange of the air duct shell made of the galvanized sheet iron so that sealing effect is good. The noise elimination sound insulation high hydrophobic environment-friendly air duct has the advantages of being convenient to install, good in sealing performance, good in durability, long in service life, good in sound absorbing effect, and capable of reducing noise and insulating sound. Due to adoption of an inner insulating layer, the air duct is good in thermal insulating performance and heat insulating effect, avoids the phenomenon of moisture condensation of an air duct system, saves energy resources, improves working environments, is good in fireproofness, and belongs to A-level non-ignitable products.
Description
(1), technical field
The utility model relates to the environment protection type airduct that a kind of existing noise elimination effect has again soundproof effect, it is widely used in the ventilating system for central air-conditioner of each building, be particularly suitable for the demanding radio data system of acoustics tonequality is performed in a radio or TV programme hall, film shooting making recording (canopy) chamber and Movie theater assembly hall, and be used for densely populated office and public place.
(2), background technique
Central air-conditioning system ventilation airduct in the building, what usually adopt is the galvanized sheet iron airduct, wraps up thermal insulating material and heat preservation protective layer for reaching the heat insulation effect outside again.Because the galvanized sheet iron airduct is the airduct of rigid material, it does not only have soundproof effect, even also the noise of equipment can be sent to the job site by airduct, therefore need to add the noise elimination accessory of silencing apparatus and bend muffler and so in the airduct pipeline.Owing to installing silencing apparatus additional, thereby space that just need to be larger (because the boundary dimension of silencing apparatus goes out greatly 200mm than the every limit of airduct size), and silencing apparatus will reach due effect, its setting position there is certain requirement, be difficult in the Practical Project accomplish, cause actual soundproof effect also to be difficult to guarantee., airduct monolateral length higher at wind speed is large or also can produce quadratic noise during with high intermediate frequency matched with blower, so that noise countermeasure is got half the result with twice the effort.In addition, the galvanized sheet iron airduct owing to expanding with heat and contract with cold, also can produce stress deformation when running into cold wind or hot blast suddenly, thereby the disagreeable sound of " loud, high-pitched sound, loud, high-pitched sound " occurs.
The composite air duct that occurs on the market in recent years, compare with the galvanized sheet iron airduct, although more convenient than iron duct aspect fabrication and installation, speed of application is fast, but most of composite air duct (such as the airduct of phenolic aldehyde aluminium foil composite air duct, color steel folder foam material, polyurethane composite air duct etc.) does not all reach the effect of noise reduction, and can only reach the B level on the fire-protection rating of material; The glass composite air duct preferably resolves the problem of noise reduction, but airduct can't reach good effect aspect sound insulation, and at the construction field (site) during crossed construction, the easy surface fracture of glass composite air duct, outward appearance is not whole after repairing, and the situation of badly broken also probably occurs.Scene protection becomes a large disadvantage of glass composite air duct.
(3), model utility content
The purpose of this utility model provides the environment protection type airduct that a kind of existing noise elimination effect has again soundproof effect, it can be widely used in the ventilating system for central air-conditioner of each building, can be suitable for especially the demanding radio data system of acoustics tonequality is performed in a radio or TV programme hall, film shooting making recording (canopy) chamber and Movie theater assembly hall, and be used for densely populated office and public place.
The utility model can solve the problem of airduct noise elimination sound insulation; The glass fibre that solves the airduct inwall easily comes off, fire-retardant, mildew-resistant, problem that humidity resistance is lower.
The technical solution of the utility model: the shell of the high hydrophobic environment protection type of this noise elimination sound insulation airduct adopts the galvanized sheet iron airduct, and the insulating liner of airduct adopts formaldehydeless environmentally-friendly centrifugal block of glass wool.If the airduct size is large, this layer liner heat-preservation cotton and galvanized sheet iron airduct are reinforced fixing with the welding nail after sticking with glue first knot again.This liner heat-preservation cotton is that, curing folded sticking with novel binders by the formaldehydeless environmentally-friendly centrifugal glass fibre of white, moulding form, glass fibre is thinner, make the feel of glass wool relatively finer and smoother, rebound elasticity is relatively good, and the heat insulation effect also centrifugally glass-wool than traditional is good; Its surface layer adopts high molecular nanometer coating, nano antibacterial mildew-resistant Chopped Strand Mat, has the functions such as good fire prevention, high hydrophobic waterproof damp proof insulation, fungus-resistant, corrosion protection, prevention glass come off.
In the above-mentioned formaldehydeless environmentally-friendly centrifugal glass fibre cotton plate, formaldehydeless environmentally-friendly centrifugal glass fibre average diameter is 3-8 μ m, and formaldehydeless centrifugally glass-wool density is 48～80kg/m
3, hydrophobic rate 〉=98%, thermal conductivity≤0.033W/m
2.K (20 ℃), burning behavior class are that the A level is not fired.
The utility model product through adopting above technical matters to produce has the following advantages:
(1) the high hydrophobic environment protection type of noise elimination sound insulation airduct is easy for installation, good airproof performance, and serviceability is good, long service life.
(2) the high hydrophobic environment protection type of noise elimination sound insulation airduct acoustically effective is good, can reduce transfer voice, reduces noise, also has simultaneously the effect of sound insulation.
(3) adopt inner thermal insulating layer, airduct thermal insulation property, effect of heat insulation are good, have avoided air-line system that the phenomenon of dewfall is arranged, and have both saved the energy, also improve working environment.
(4) the macromolecule undercoating forms the uniform moistureproof and waterproof protective film of one deck on the glass wool surface, and product has good moisture resistance performance, and airduct can effectively intercept the propagation of steam and invade tube wall.
(5) refractory nature is good, belongs to the A level and does not fire product.
(6) the high hydrophobic environment protection type of noise elimination sound insulation airduct glass can not occur and comes off in its installation, using process, thereby can not damage health, can be to environment.
The utility model adopts that the fiber of white formaldehydeless environmentally-friendly centrifugal glass fibre is elongated, cotton is evenly distributed, rebound elasticity good, have and common centrifugally glass-wool same excellent physical property and thermal characteristics, simultaneously because its Bond that adopts is formaldehyde-free binder, the Bond that contains formaldehyde, benzene, uric acid resin that is different from the simple glass cotton, so harmless without impact, be adapted to especially the field higher to environmental requirement, such as personnel than the school of comparatively dense, office space, gymnasium, Movie theater etc.
