Technical Field
The utility model relates to a dustproof cloth field, concretely relates to high air permeability environmental protection polyester dustproof cloth.
Background
In China, ten years ago, countries such as Japan, America, Britain, Australia and the like carry out deep research and application on the wind-shielding and dust-suppression technology. Over two decades ago, wind screens have been used in japan to control dust pollution in port open coal yards. The research on the windproof net dustproof technology in China is late, and the special research work on the dustproof mechanism, the processing technology and the engineering design is less. The hydrodynamics teaching and research room of Wuhan's institute of Hydraulic engineering, used environmental wind tunnel test in the middle of the 80 s in combination with the research on the wind-shielding and dust-suppression measures of the coal yard at the Soy Zhujia dock to test the relevant structural parameters of the wind-shielding net and to provide some problems to be solved.
The water transportation scientific research institute of the department of transportation cooperates with an environmental aeromechanics research laboratory of the environmental science center of Beijing university in the early 90 s, and combines with the coal yard of the Qinhuang island to set up the dustproof mechanism of the windproof net and the main structural parameters of the windproof net, such as the characteristic aperture ratio, the material of the windproof net and the dust reduction effect of the windproof net on the coal yard.
In recent years, research work has been carried out on the river harbor engineering of taiwan oceanic university in the aspects of a windproof net multilayer structure and a net rear air turbulence structure.
The dust screen is also called 'wind-proof dust suppression screen' and 'wind-break wall', which is an environmental protection project for controlling the dust pollution in the open-air stock yard. The method is widely applied to bulk material ports, fuel storage yards of thermal power plants, raw material fuel storage yards of iron and steel enterprises, raw material fuel storage yards of chemical enterprises, coal discharging storage yards of coal mines and the like.
What use commonly on the present building site is that the dust screen covers loess exposed area, easy dusting material, has fire control special requirements project building site to select for use "geotechnological cloth" of fire-retardant material, and the exposed area of loess along the railway line and high-pressure corridor along the line also need use "geotechnological cloth" to cover, and fix according to the standard, avoid appearing being blown by the strong wind and influence the high-speed railway transportation, cause the incident.
The conventional common dustproof cloth has a single structure and low tensile strength and deformation resistance, and is easily damaged by wind, sunlight, acid rain and the like when being used outdoors. When in use, the soil dust cloth is easy to slide relative to the surrounding medium due to small friction force.
SUMMERY OF THE UTILITY MODEL
The utility model provides a high air permeability environmental protection polyester dustproof cloth can discharge the steam of dustproof cloth below fast, increases air permeability, prevents that ponding from causing the corruption.
Realize the technical scheme of the utility model is that:

Detailed Description
The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without any creative effort belong to the protection scope of the present invention.
As shown in fig. 1, a high air permeability environmental protection polyester dustproof cloth, includes dustproof cloth body 1, dustproof cloth body 1 from the top down includes polyester environmental protection dustproof layer 2, permeable layer 3, fire-retardant layer 4 and skid resistant course 5 in proper order, this internal sleeve pipe 6 that is equipped with of dustproof cloth, be equipped with capillary tube bundle 7 and waterproof ventilated membrane 8 in the sleeve pipe 6, the top of capillary tube bundle 7 is arranged in to waterproof ventilated membrane 8.
The utility model discloses dustproof cloth permeable layer 3 can seep water fast, prevents that the rainwater from piling up on dustproof cloth, arouses ponding phenomenon, and permeable layer 3 can adopt current PET non-woven fabrics or cotton material to make; fire-retardant layer 4 is made for the asbestos material, the asbestos has high fire resistance, electrical insulation and thermal insulation, important fire prevention, insulating and insulation material, the asbestos material can prevent dustproof cloth conflagration phenomenon, 5 lower extremes of skid resistant course are equipped with wave structure 9, the skid resistant course adopts materials such as carbon fiber to make, carbon fiber material itself has big coefficient of friction, can prevent that dustproof cloth from sliding, wave structure 9 that on the other hand set up has improved coefficient of friction, the further non-skid property of consolidating.
Dustproof cloth generally is used for spaciousness such as building site, suffers wind-blowing sun for a long time and drenches with rain, if dustproof cloth is easy ponding below airtight, and ponding evaporates easily under the high temperature, and dustproof cloth is early to the corruption easily, reduces life, the utility model discloses set up sleeve pipe 6 in dustproof cloth, capillary bundle 7 that sleeve pipe 6 set up, capillary bundle 7 comprises a plurality of capillary copper pipes, and capillary copper pipe's internal diameter is 0.5mm ~6mm, and capillary copper pipe forms capillary bundle through glued mode or hot melt adhesive bonding mode.
