Description
Technical field
The utility model is related to a kind of airduct, specifically a kind of damp-proof wear-resistant airduct.
Background technology
Airduct, is the pipe-line system for conveying and being distributed for air.There are two kinds of composite air duct and inorganic airduct.Airduct can be pressed
Cross sectional shape and material classification.It is in gaps such as seaming seam, riveted seam, flange flange corners that airduct, which makes stainless steel airduct and made,
Coat fluid sealant in place（Such as neutral density glass glue）.Surface dirt and greasy dirt should be removed before applying fluid sealant.By cross sectional shape, airduct can divide
For circular duct, rectangular air duct, oblate airduct etc. is a variety of, and wherein circular duct resistance is minimum but height dimension is maximum, makes multiple
It is miscellaneous.So using based on rectangular air duct.By material, airduct can be divided into metal bellows, composite air duct, macromolecule airduct.
Existing airduct wears no resistance, and service life is short, and airduct is moist, is easily infected with dust, makes bacteria breed in airduct, shadow
Sound is used.
The content of the invention
The purpose of this utility model is that providing one kind increases the service life, and lifts the damp-proof wear-resistant airduct of overall performance,
To solve the problems mentioned in the above background technology.
To achieve the above object, the utility model provides following technical scheme：
Wearing layer is scribbled on the outside of a kind of damp-proof wear-resistant airduct, including polyethylene layer, polyethylene layer；In the polyethylene layer
Inner side be provided with EPS layers；Described EPS layers inner side is provided with damp-proof layer；The inner side of damp-proof layer sets interior plastic foil.
Further：The thickness of the polyethylene layer is 1~2mm.
Further：The material of the wearing layer is POM.
Further：Described EPS layers is expandable polystyrene.
Further：The damp-proof layer is powdered desiccant layer, the particle diameter of the powdered drier for 30~
40 microns.
Further：Multiple micropores, a diameter of 20~30 microns of micropore are evenly arranged with the interior plastic foil.
Compared with prior art, the beneficial effects of the utility model are：The wearing layer that surface of the present utility model is coated with increases
The wearability of high wind pipe, can be applied to different environment, extend the service life of airduct；EPS have light weight, it is inexpensive,
Low thermal conductivity, water imbibition are small, electrical insulation capability is good, sound insulation, the advantages of shockproof, moistureproof, moulding process is simple, lifting airduct it is whole
Body performance, damp-proof layer can be by the water vapor absorption in airduct, it is to avoid have ponding on tube wall and breed bacteria, it is ensured that airduct makes safely
With.
Brief description of the drawings
Fig. 1 is a kind of structural representation of damp-proof wear-resistant airduct.
In figure：1- polyethylene layers, 2- wearing layers, 3-EPS layers, 4- damp-proof layers, plastic foil in 5-.
Embodiment
Below in conjunction with the accompanying drawing in the utility model embodiment, the technical scheme in the utility model embodiment is carried out
