The formaldehydeless environment protection type pipe silencer of the utility model, adopt formaldehydeless environment protection type insulation glass wool to solve defective and the deficiency of traditional glass cotton, better be applied to the demanding industrial building industry of ventilation system has been made major contribution to building indoor environmental quality and occupant's level of comfort.
The purpose of this utility model provides the formaldehydeless environment protection type pipe silencer that a kind of specialized designs is used for air-conditioning, ventilation system, and its noise reduction glass wool solves thoroughly eliminates the technical problem that formaldehyde pollutes in the simple glass cotton; Solve the low problem of the cotton internal surface fireproof performance of simple glass.Be applicable to that all running environment noises adhere to specification, broadcast record chamber, concert hall etc. as TV station, or be used to build quiet comfortable work, living environment, air-line system as office, hotel, market, workshop etc., be applicable to the noise that decay ventilator or discharging flue gas produce, make the comfortable formaldehydeless environment protection type pipe silencer of indoor environment.
The formaldehydeless environment protection type trumpet type silencer of the utility model is that a kind of specialized designs is used for the air conditioner ventilating system pipeline; absorb acoustic energy, reduce noise and play the formaldehydeless environment protection type trumpet type silencer of noise elimination effect; it is characterized in that overcoat is the galvanized sheet iron protective layer; interior noise reduction layer adopts formaldehydeless environmental protection glass wool, the zinc-plated perforated plate covering protection of formaldehydeless environmental protection glass wool external application.The overcoat protective layer is a galvanized sheet iron; the thickness of iron sheet overcoat is 0.5mm to 1.2mm; internal layer absorbent treatment at silencing apparatus adopts the formaldehydeless environment protection type heat-insulating and sound-absorbing of the utility model glass wool liner; promptly adopt the cotton plate of the formaldehydeless centrifugal glass fibre of low density white; the cotton plate of the formaldehydeless centrifugal glass fibre of low density white is glued by formaldehyde-free binder and fibre lay-up and forms, and its glass fibre average diameter is 5-8 μ m.
The technical solution of the utility model:
The formaldehydeless environment protection type pipe silencer of the utility model is that a kind of specialized designs is used for the ducted formaldehydeless environment protection type trumpet type silencer of air conditioner ventilating system; it is characterized in that overcoat is the galvanized sheet iron protective layer; interior noise reduction layer adopts formaldehydeless environmental protection glass wool, and the baffler inwall formaldehydeless environmental protection glass wool by zinc-plated perforated plate covering protection.Absorbent treatment adopts the cotton plate of the formaldehydeless centrifugal glass fibre of low density white, and the cotton plate of the formaldehydeless centrifugal glass fibre of low density white is glued by formaldehyde-free binder and fibre lay-up and forms, and its glass fibre average diameter is 5-8 μ m.It can be divided into two kinds of circular formaldehydeless environment protection type pipe silencer and the formaldehydeless environment protection type pipe silencers of rectangle, and its profile is circle or rectangle, and the thickness of iron sheet overcoat is 0.5mm to 1.2mm.Formaldehydeless environment protection type trumpet type silencer is easy to fabrication and installation, and it is stable and reliable for performance, is widely used in TV station and broadcasts record chamber, concert hall etc., or be used to build quiet comfortable work, living environment, as the air-line system in office, hotel, market, workshop etc.
The utility model is compared the beneficial effect that has with existing conventional art:
Adopt formaldehydeless environment protection type heat-insulating and sound-absorbing glass wool in the formaldehydeless environment protection type pipe silencer of the utility model, this acoustical cotton adopts the manufacturing of formaldehydeless environment-friendly white glass fibre cotton to form.Formaldehydeless environment-friendly white heat-insulating and sound-absorbing glass wool is done the part adjustment to glass fibre cotton composition of raw materials and moulding process on traditional centrifugally glass-wool basis, make that glass fibre and formaldehyde-free binder are folded sticking, curing, moulding.The Bond that formaldehydeless environment-friendly white heat-insulating and sound-absorbing glass wool adopts is different fully with the traditional glass cotton, is a kind of formaldehydeless acrylic adhesive.It has casted off poisonous, harmful matters such as phenol, formaldehyde, urea once and for all, and the formaldehyde of having stopped pipe in the simple glass cotton pollutes.The formaldehydeless environment protection type pipe silencer of the utility model outside having the function of conventional muffler, has environmental-protecting performance simultaneously, and the health of human body is not had influence.
