The utility model relates to a kind of environment protection type airduct that sound deadening, high hydrophobic are arranged, 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 traditional airduct adopted usually is galvanized sheet iron airduct and glass fibre reinforced plastic blast pipe.Making, the installation period of tradition airduct is long, speed is slow, and line size and move towards when change time-consuming installs silencing apparatus additional, the space that needs are larger, and increased installation difficulty and workload.Thermal insulation layer is on-the-spot the installation after airduct installs, operation is loaded down with trivial details, in the difficult assurance of air duct flange place insulation thickness with without insulation, to produce cold bridge phenomenon, should stop necessary thermal insulation layer fitting operation space around the airduct, otherwise thermal insulation layer covers the uniformity sometimes because erection clearance enough is not difficult for guaranteeing, appearance is not attractive in appearance, heavier because of it, will increase the carrying of building.Because the glass fibre reinforced plastic blast pipe pipeline is heavy, be difficult for carrying, intensity is higher, but relatively more fragile, is subject to collision and causes shortcake to split and damaged, need to process in factory, and processing loss is large, has deterioration phenomenon, in engineering, use at present seldom.
Although general composite glassfibre air duct is more convenient than iron duct aspect fabrication and installation, speed of application is fast, composite glassfibre air duct has also solved the problem of airduct noise reduction preferably, and airduct is still waiting to improve in the performance of anticorrosive mildewproof waterproof; And composite glassfibre air duct mostly adopts traditional glass wool sheet material.This traditional glass wool adopts phenolic resin as the main binding agent, in glass wool, there are the harmful matters such as free formaldehyde, phenol, urea to exist, can in air, discharge for a long time low dosage formaldehyde, cause that some people drops tears, eye and larynx have burning sensation, feel sick and expiratory dyspnea, also can cause human body chronic respiratory disease, allergic stimulated, very easily abnormal pulmonary function, dysfunction of liver and immunologic dysfunction, allotriosmia symptom occur, the formaldehyde of high concentration even can become human carcinogenic substance.
(3), model utility content
The utility model provides a kind of environment protection type airduct with erasure 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 adopts nontoxic high molecular nanometer coating and formaldehydeless composite glass fiber felt, when effectively solving airduct noise reduction problem, the glass fibre that has solved the airduct inwall easily comes off, fire-retardant, mildew-resistant, problem that humidity resistance is lower, have good fire prevention, waterproof, protection against the tide, mildew-resistant, corrosion-resistant, prevent the functions such as fibre shedding, effectively guaranteed the cleaning of airduct pipe interior air and pure and fresh, Long Term Contact can not make human body produce bad reaction.
The technical solution of the utility model: the high hydrophobic environment protection type of this noise reduction airduct is that formaldehydeless environmentally-friendly centrifugal block of glass wool take high unit weight is as base material, the surface is the inferior light veneer of one deck compound moisture-proof anticorrosive aluminium foil veneer or W38 moisture-proof anticorrosive polypropylene, internal surface is the anticorrosion moistureproof composite glass fiber felt of one deck, reinforces and makes through cutting, bonding, rubber belt sealing box.The airduct quality is light, and simple installation need not flange and connects, and adopts male and female mouth insertion method, and an end of airduct is female mouthful for a male mouthful the other end.
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 environmentally-friendly centrifugal glass wool density is 80～100kg/m
3, hydrophobic rate 〉=98%, thermal conductivity≤0.033W/m
2.K (25 ℃), noise reduction coefficient (NRC) 7.6, 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 reduction airduct simple installation, good airproof performance is easy to repair.
(2) the high hydrophobic environment protection type of noise reduction airduct has good sound absorption qualities.
(3) the high hydrophobic environment protection type of noise reduction airduct has superpower waterproof damp proof insulation performance.Airduct uses high molecular nanometer undercoating material, through especially processing, forms the uniform moistureproof and waterproof protective film of one deck on the centrifugally glass-wool surface, can effectively intercept steam and invade the airduct tube wall, guarantees the endurance of air-line system.
(4) the high hydrophobic environment protection type of noise reduction airduct adopts the male and female mouth to peg graft, and adds the Placement of chewing-gum band sealing, has the performance that low air quantity is revealed, reduced the energy consumption energy saving.
(5) the high hydrophobic environment protection type of noise reduction airduct has excellent Safety performance.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.
