Abstract
The invention discloses a light environment-friendly heat insulation glass wool tube which comprises a dustproof film, an inner heat insulation layer, a reinforcing net, an outer heat insulation layer and a heat insulation film. The inner heat insulation layer wraps the outside of the dustproof film, the reinforcing net is arranged between the inner heat insulation layer and the outer heat insulation layer, and the heat insulation film wraps the surface of the outer heat insulation layer. The dustproof film is made of low-density high-pressure polyethylene and capable of preventing glass fiber on the inner surface of the glass wool tube from flying off. The inner heat insulation layer and the outer heat insulation layer are made of light environment-friendly glass wool blankets free of harmful substances like formaldehyde and good in heat insulation effect. The reinforcing net is a galvanized steel wire net and capable of remarkably improving anti-deformation capability of the glass wool tube. The heat insulation film is an aluminum foil composite polyethylene glycol terephthalate (PET) film and is capable of reflecting heat energy radiated to the surface of the glass wool tube and stopping heat transfer. The light environment-friendly heat insulation glass wool tube is low in unit weight, environmentally friendly, safe, good in long-term heat insulation effect, high in strength and capable of being applied to pipeline heat insulation in the industries of petroleum, chemical engineering, building, food cold storage and the like.
Description
Technical field
The present invention relates to glass wool pipe field, be specifically related to the cotton pipe of a kind of light-weight environment-friendly type heat-protecting glass.
Background technique
Traditional glass wool pipe is a kind of insulation pipe being become by aluminium foil composite glass wool felt, because the pipeline of this material has insulation, waterproof, the characteristic such as anticorrosion, therefore by a large number for civil building, heat supply pipeline, air-conditioning, the insulation of chiller plant.But, in actual applications, the use of the cotton pipe of heat insulation glass exists some problems, be mainly manifested in the following aspects: one, the heat-preservation cotton felt in most of glass wool pipe is used phenolic resin as Bond, in Bond, contain the harmful matters such as free formaldehyde, urea, phenol, human body is damaged or befouling environment; Two, glass wool pipe bulk density is larger, is not easy to installation, also to maintaining, brings very large difficulty; Three, after glass wool pipe is used a period of time, thermal conductivity raises, and effect of heat insulation significantly reduces; Four, glass wool pipe intensity is lower, during in particular for tubing, meets the weight easy deformed damaged of exerting pressure.The existence of these problems has limited development and the application of glass wool pipe.
201636493 U(notice of authorization days of Chinese patent CN are on November 17th, 2010) a kind of formaldehydeless environment protecting thermal insulating glass wool rigid section disclosed, the advantage of this glass wool rigid section is to use formaldehydeless centrifugally glass-wool plate as thermal insulation layer, has solved the technical problem of eliminating formaldehyde pollution; The shortcoming of this glass wool rigid section is that unit weight is higher, has reached 55 ~ 90Kg/m
3, be not easy to installation; This glass wool rigid section is only covered with lined with reinforced ribs aluminium foil on the surface of block of glass wool simultaneously, and intensity is very low, easily deformable damage.
Summary of the invention
Technical problem to be solved by this invention is to overcome the deficiencies in the prior art, and a kind of light-weight environment-friendly, good heat-insulation effect are provided, and has the glass wool pipe of higher-strength.This glass wool pipe does not contain harmful and air-polluting material, and unit weight is low, and heat-shielding performance long term maintenance is in higher level, there is higher intensity, solved the cotton pipe of simple glass and discharged harmful gas, weight is difficult for greatly installing, the problem that insufficient strength and effect of heat insulation are bad.
Technological scheme of the present invention is: the cotton pipe of a kind of light-weight environment-friendly type heat-protecting glass, and this glass wool pipe comprises: dustproof membrane, inner thermal insulating layer, strengthening net, external thermal insulation, heat insulation film; The outside of described dustproof membrane is covered with inner thermal insulating layer, between inner thermal insulating layer and external thermal insulation, is provided with strengthening net, and external thermal insulation surface is covered with heat insulation film.Wherein dustproof membrane is low-density high-pressure polyethylene, and thickness is 100 ~ 200 μ m, can prevent that glass wool pipe internal surface glass fibre from dispersing; Inner thermal insulating layer and external thermal insulation are light-weight environment-friendly type blanket of glass wool, do not contain the harmful matters such as formaldehyde, have good heat insulating effect, and inner thermal insulating layer thickness is 15 ~ 20mm, and external thermal insulation thickness is 10 ~ 15mm; Strengthening net is Galvanized Steel Wire Netting, and order number is 15 ~ 25, can significantly improve the resistance capacity to deformation of glass wool pipe; Heat insulation film is the compound PET film of aluminium foil, and thickness is 70 ~ 100 μ m, and energy reflected radiation, to the heat energy of the cotton tube-surface of glass wool, stops heat transmission.
beneficial effect
The beneficial effect that the present invention compared with prior art has is: the bulk density of (1) glass wool pipe is light, constructability installation and maintenance maintenance; (2) Environmental Safety, the not harmful and air-polluting material such as Diazolidinyl Urea; (3) glass wool pipe thermal conductivity remained on 0.005 ~ 0.008W/(mk in 2 ~ 3 years), heat insulation effect is stable good; (4) intensity is high, can bear larger external force, can directly be used as tubing.
