Therefore, hydrophilic self-cleaning glass is the mainstream of market research. The self-cleaning function of the self-cleaning glass is mainly based on the action of a photocatalyst, electron transition is completed by absorbing sunlight to reach an excited state, and the effect of degrading pollutants is achieved by utilizing active groups.
The preparation of the self-cleaning glass is still an off-line coating method which is mostly used in China at present, and a self-cleaning film layer is coated on a glass substrate by a sol-gel method, a high-temperature sintering method or a self-cleaning liquid spraying method and the like, however, the off-line coating method has a plurality of problems, firstly, the bonding firmness of the film layer and the substrate is insufficient, and the service life is short; secondly, the defects of the off-line coating layer are more, and the photolysis index of the coating layer after photocatalysis is lower; and the film layer and the substrate or the film layer are mutually influenced, and the functional layer has more impurities to influence the performance. Particularly, for the glass decoration plate on the building outer wall, the glass decoration plate is polluted by the outside for a long time, and the coating film on the glass can not effectively clean the glass for a long time at present, so that the glass decoration plate on the building outer wall is required to be protected by the efficient coating film which can be used for a long time.

In the using process of the scheme, after the surface of the composite membrane 4 is covered by dust, when the composite membrane 4 is impacted by external air flow, the air flow discontinuously enters the tympanic membrane 5 through the air holes on the composite membrane 4, so that the tympanic membrane 5 expands, and further the convex membrane 3 exerts a reaction force on the tympanic membrane 5, so that the tympanic membrane 5 vibrates, the composite membrane 4 is driven to vibrate when the tympanic membrane 5 vibrates, the dust desorption of the composite membrane 4 through vibration is realized, in the process that the air flow passes through the tympanic membrane 5, water vapor in the air flow is carried by the air flow, so that the air flow discharged from the tympanic membrane 5 contains water vapor, and the air flow carrying the water vapor discharged from the membrane scrubs the surface of the composite membrane 4; after the surface of the composite membrane 4 is covered by dust, the overall heat dissipation efficiency of the membrane is reduced, after the membrane is irradiated by sunlight, the expansion ball 303 in the convex membrane 3 is heated and expanded, so that the tympanic membrane 5 is extruded, the hydrophilic ball 6 in the tympanic membrane 5 is extruded, the hydrophilic ball 6 is extruded to release water vapor absorbed at ordinary times, the surface of the composite membrane 4 seeps water, the water is evaporated under the irradiation of the sunlight, part of dust on the surface of the composite membrane 4 is carried away from the surface of the composite membrane 4 along with air flow during the evaporation of the water, the self-cleaning of the composite membrane 4 is realized, after the water is evaporated, the overall temperature of the composite membrane 4 is reduced, alcohol in the expansion ball 303 is cooled and liquefied, so that the expansion ball 303 is contracted and liquefied, the tympanic membrane 5 is elastically reset, and the hydrophilic ball 6 in the tympanic membrane 5 stops releasing water,
this scheme is through when the rete on the plaque is strikeed repeatedly to external air current, erodees the rete surface when making the outside flow of air current rete inner wall, erodees the in-process vibrations rete, realizes self-cleaning to the plaque surface, and the hydrophilic ball 6 absorptive steam carries out the rete self-cleaning at high temperature environment accessible release ordinary times, and self-cleaning frequency is high, is difficult for making the rete surface area hold a large amount of dust.
The foregoing is only a preferred embodiment of the present invention; the scope of the invention is not limited thereto. Any person skilled in the art should be able to cover the technical scope of the present invention by equivalent or modified solutions and modifications within the technical scope of the present invention.
