Description
[technical field]
The utility model relates to a kind of low radiation glass with clean, belongs to the glass coating technical field.
[background technology]
Low emissivity glass, English is Low Emissivity Glass, abbreviates Low-E glass as.Low-E glass is that to plate the film that multiple layer metal or other compounds form at glass surface be product.This product has high transmittance to visible light, and infrared rays (selecting infrared especially) is had very high reflectivity, has excellent heat insulation property.According to production technique, it is divided into off-line Low-E glass and online Low-E glass.
Off-line Low-E glass separates with floatation glass production line, generally adopts magnetically controlled sputter method production, is coated with stratified film on sheet glass successively, realizes the Low-E effect.Its advantage is to have best low radiation effect, and emissivity values can reach 0.05, even about 0.04.Can only about 0.15 and the radiant ratio of online Low-E is minimum.No. the 96104321.0th, pertinent literature such as Chinese patent application, Chinese patent No. 200410018113.0, No. 200420083199, No. 93105250.5.
Online Low-E glass is to realize in the production process of float glass, mainly adopts chemical vapor deposition (CVD) method or high temperature pyrolysis spraying method.Its advantage is that the tack between rete and the sheet glass is strong, can transport in the strange land, but the monolithic use also can be carried out various deep processings, as tempering, hot bending etc.
Chinese patent discloses a kind of method of float glass process online production low radiation coated glass for No. 01142650.0, this patent utilization CVD method, and the glass surface deposition low-radiation film layer in heat has 2 layers.The first layer is a screen layer, is made up of silicon oxide, the boron oxide of carbon dope; The second layer is made up of stannic oxide, the weisspiessglanz of doped with fluorine, phosphorus for low radiating layer.
Bibliographical information about glass with clean is many.Self-cleaning glass is glass with clean again, and multiple production technique is arranged at present both at home and abroad, as sol-gel technology, off-line magnetron sputtering or vacuum deposition process, online CVD (chemical vapour deposition) and various dip-coating, spraying coating process.
Online glass with clean is produced in the production process of float glass, compares with the off-line glass with clean, online glass with clean has mass or produces quantized advantage, realize serialization production, thereby production efficiency is provided, also reduced production cost on the other hand.The principal feature of online glass with clean is its processing characteristics, and this product can carry out strange land transportation as common float glass, also can carry out all kinds of deep processings operations, as cut, mill, hollow, tempering, hot bending, interlayer etc.The technology of making online glass with clean at present both at home and abroad mainly contains online CVD method.
The off-line glass with clean is compared with online glass with clean, does not realize serialization production, does not combine with floatation glass production line, so production efficiency is lower, production cost is higher.Shortcoming is that rete is relatively poor in the tack of glass surface, can not strange land transportation and operation, except blank operation in carrying out, can not carry out other deep processings operations, as hot bending, tempering etc.The production method that all belongs to the off-line glass with clean as sol-gel method, magnetron sputtering method, vacuum deposition method, spraying method, dip coating etc.
Online CVD method, be by chemical vapour deposition CVD method with titanium dioxide deposition to the sheet glass that moves of heat, and sheet glass is clean, this method generally in molten tin bath temperature be position between 650 ℃-720 ℃, this method has also made full use of the heat of glass pane surface in the float glass process, and do not need as sol-gel method, to reheat rete is solidified, saved the energy; And realized serialization production.This method generally is that liquid or solid-state organo-metallic titanium salt are gasified by thin-film evaporator, and under the drive of rare gas elementes such as nitrogen, raw material is deposited on the glass pane surface that moves of heat by decomposition under gas phase state like this, forms rete.The document that utilizes the CVD method to produce glass with clean has Chinese patent application No. 03130468.0, No. 02815882.2, No. 00818185.3, and Chinese patent No. 00808643.5, No. 200480007970.9, No. 01802678.8.
Magnetically controlled sputter method utilizes existing magnetron sputtering film device, by metal titanium is splashed to glass surface, generates titanium deoxid film in the glass surface oxidation, makes glass surface have certain wetting ability, and reaches self-cleaning effect.The document that utilizes this method to generate glass with clean has Chinese patent No. 99815987.5, No. 01802678.8, and No. the 02805314.1st, Chinese patent application.
Sol-gel process, titanium dioxide is mixed with colloidal sol, again glass is put into that this colloidal sol soaks into the mode that lifts and the even self-cleaning rete of two surface applied one decks that makes sheet glass, again with glass in High Temperature Furnaces Heating Apparatus, at the temperature sintering that surpasses 500 ℃, just can finish the conversion of rutile crystal type behind the several hrs to anatase crystal type.The document that utilizes this method to make glass with clean has Chinese patent No. 02147089.8, and Chinese patent application No. 02822422.1, No. 03817836.2.
