Pipe has solved the defective and the deficiency of pipe in the traditional glass cotton in the formaldehydeless environment protection type insulation of the utility model glass wool, better be applied to the demanding industrial building industry of air-line system has been made major contribution to building indoor environmental quality and occupant's level of comfort.
Existing issues such as the noise of metal air-line system, tube wall heat exchange and water-setting point can be in control solution by installing in the formaldehydeless environment protection type insulation glass wool.Air-line system can be controlled noise that airduct produces, reduce the heat exchange of metal pipe-wall and water-setting is dropped to minimum point after insulation.
The purpose of this utility model provides the interior pipe of formaldehydeless environment protection type insulation glass wool that a kind of specialized designs is used for air-conditioning, heating, ventilation system, solves thoroughly to eliminate to be incubated the technical problem that formaldehyde pollutes in the pipe in the glass wool; Solve the low problem of pipe internal surface fireproof performance in the glass wool; Solve the big problem of pipe internal surface frictional force in the glass wool.Be applicable to that all running environment reach 25.4 meter per seconds for high gas flow speed and temperature is up to 121 ℃ metal air-line system.
The technical solution of the utility model: pipe is that inorganic glass fiber manufacturing by the formaldehydeless environmental protection acrylic thermosetting resin that bondd forms in the formaldehydeless environment protection type heat preserving sound deadening glass wool, durable in use, the fire prevention that can clean internal surface is provided, and frictional loss is dropped to minimum.Pipe is easy to make and be installed in all metal air-line systems in the formaldehydeless environment protection type heat preserving sound deadening glass wool, improves performance and reliability.The utility model has pipe in rectangle and the circular two kinds of formaldehydeless environment protection type heat preserving sound deadening glass wools.Pipe does not wait from 152mm to 1.83m in the wherein circular formaldehydeless environment protection type insulation glass wool.
The utility model is compared the beneficial effect that has with existing conventional art:
Pipe adopts the manufacturing of formaldehydeless environment-friendly white glass fibre cotton to form in the formaldehydeless environment protection type heat preserving sound deadening of the utility model glass wool.Formaldehydeless environment-friendly white glass fibre cotton 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 glass fibre cotton 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 utlity model has following advantage:
(1) improve the building indoor environment, pipe improves indoor environmental quality by helping control temperature and sound in the formaldehydeless environmental protection glass.
(2) strength is strong, can bear high wind speed, is the abrasion test method on basis according to UL181, and airduct liner high wind speed after tested reaches 63.5 meter per seconds.
(3) energy saving, the heat exchange by the control tube wall realizes the control to the energy.
(4) dust protection and fouling performance are good, help prevent dirt or dust to infiltrate the basic unit of airduct liner by the airflow layer that scribbles the acrylate copolymer surface.
The utility model adopts formaldehydeless environmental protection glass wool and acrylic adhesive, has abandoned harmful matters such as phenol, formaldehyde, urea, does not contain harmful matters such as ammonia, benzene, and is tasteless nontoxic, and the protection health is improved working environment.The fiber of formaldehydeless environment protection type glass wool is elongated, cotton is evenly distributed, rebound elasticity is good, has and common centrifugally glass-wool same excellent physical property and thermal characteristics.Formaldehydeless environment protection type glass wool is natural pure white, makes product more beautiful, attractive in appearance.The high density centrifugal glass fibre plate of producing with formaldehyde-free binder authenticates by test of ES1350 IAQ and SCS environment.Test result shows that this product can not discharge pollutant, thereby can not pollute indoor environment.
