(1), plating deielectric-coating---be that sensitization is handled: with nozzle with SnCl
2Solution is sprayed on the substrate of cleaning, drying equably, and the treatment time is 2-3 minute.The substrate that has plated deielectric-coating is fully washed, wash the no longer residual Cl of having to the substrate
-Be degree.
(2), the plating functional membrane---silverskin: with nozzle with silver diamminohydroxide (Ag (NH
3)
2OH) solution equably spraying plating on the substrate that has plated deielectric-coating, use another nozzle simultaneously with reduced liquid---spraying plating is on the above-mentioned substrate that has been coated with deielectric-coating equably for glucose solution, and the monolithic spraying plating time is 50-70 second.
(3), protective film coating: polymethyl methacrylate is dissolved in the acetone, and making its viscosity is 3-8d PaS, with nozzle with this solution equably spraying plating on the substrate that is coated with silverskin.
Between edging and cleaning, drying operation, increase by one and paste the boundary belt operation: promptly stick one deck protective tapes in the substrate perimeter of need plated film, adhesive tape is wide to be 30-50mm.
Described SnCl
2The concentration of solution is 5-27g/l; The concentration of silver diamminohydroxide solution is 0.1-1.5%; The concentration of glucose solution is 3-10%.
The pressure of described nozzle is 2-3Kgf/cm
2, the bore of nozzle is 0.2-0.3mm.
Described plating functional membrane operation and blowing drying process thereafter all need to carry out under protective atmosphere, and the gas of described protective atmosphere is nitrogen or rare gas element.
The sewage that cleaning, drying and sensitization are handled all needs handle in the sewage disposal operation, could discharge after reaching emission standard.
Close in the double glazing behind the sheet and be filled with argon gas or other rare gas element.
The present invention has adopted that a kind of silver-plated membrane method of technology maturation---the silver mirror reaction method is carried out the plated film of slide, it has, and facility investment is little, cost is low, simple to operate, can be applicable to advantages such as different industrial scale application.Very even with the silverskin that the silver mirror reaction method is produced, very thin (generally at 0.03-0.06 μ m), visible light transmissivity is more than 70%.Be noted that here the present invention is based on the principle of silver mirror reaction, it and the silver-plated of common silver mirror glass are the two entirely different things of fundamental difference, and difference has:
(1), the silverskin of common silver mirror glass is very thick, generally about 80 μ m, and silverskin of the present invention is very thin, only has only 0.03-0.06 μ m.
(2), the silver plating liquid concentration of common silver mirror glass is very big, generally about 5%, and silver plating liquid concentration of the present invention is very little, only has only 0.1-1.5%.
(3), the protective membrane of common silver mirror glass is copper or opaque paint, and the protective membrane of the present invention splendid polymethyl methacrylate that is transparency; Thereby common silver mirror glassy membrane visible light transmissivity is below 20%, and rete visible light transmissivity of the present invention is more than 70%; Be lighttight after the plated film of common silver mirror glass is finished, and the transmittance of double glazing finished product of the present invention still can reach more than 65%.
(4) technological measure that is adopted also is different, and nozzle diameter is bigger during common silver mirror glass spraying plating, is generally 0.76mm, and nozzle diameter of the present invention 0.28mm or littler only.
(5) and the reaction times of the present invention is about 1 minute generally about 3-5 minute the reaction times of common silver mirror glass coating.
Because silver plating liquid concentration is low, very easily oxidized, the silver-plated and blowing protective atmosphere that drying process adopted has avoided silverskin oxidized in process of production, thereby has guaranteed the performance of silverskin.
The present invention also is coated with layer protecting film on silverskin, this protective membrane is a polymethyl methacrylate, and it claims PMMA plastics (synthetic glass) again, and its transparency is fabulous, and intensity is higher, and certain heat-resisting winter hardiness is arranged, and corrosion-resistant, insulativity is good.Therefore, the visible light transmissivity of low-emission coated double glazing that uses explained hereafter of the present invention is greater than 65%, the reflectivity of infrared rays (heat energy) is greater than 75%, buildings uses ordinary insulating glass to reach about 50% than single-glass is energy-conservation, and uses the silver plated low-emission coated double glazing of silver mirror reaction method of the present invention to reach about 70% than single-glass is energy-conservation.
Because the coating that the double glazing sealing agent is not pasted plated film needs limit portion rete is ground off and could paste, and has increased production cost and operation expense thus, has prolonged the production cycle.The present invention has adopted before plated film the measure of pasting boundary belt earlier, tears boundary belt again and just can directly paste and be assembled into double glazing after coating film treatment is intact, has saved operation and has saved cost.
