再付着する問題があった。2. Description of the Related Art Hydrofluoric acid solutions and alkali metal hydroxide solutions have conventionally been used as film stripping agents. However, since hydrofluoric acid corrodes the glass substrate and requires attention during use, the object is mainly plastics substrate, and the glass is avoided. The hydroxide solution has a low dissolving power, and there is a problem that solute precipitates after dissolution and re-adheres to the cleaning surface.

The vapor deposition film and / or deposits on the surface are dissolved and removed by the action of the chelating agent. Sodium hydroxide is used to maintain the pH at which the chelating agent acts and to stabilize the chelate. Further, diethanolamine was added in order to prevent the precipitation of the generated chelate, thereby achieving the object.

防止できる。To carry out the stripping, the target object is immersed in the stripping agent or a solution diluted with water according to the purpose to remove the deposited film and / or the attached matter. If the solution temperature is raised to 40 to 60 ° C., the time required for removal can be reduced. The required time depends on the thickness and type of the object to be removed. If the ratio of sodium hydroxide is too high, the glass or plastics as a base material may be adversely affected. If the amount of diethanolamine is too large, there is no effect on peeling and washing, but the BOD load of the washing liquid in the subsequent step increases. If the amount is too small, chelate is precipitated, and the intended purpose is not achieved. If considering the versatility, sodium hydroxide 5.0~7.0w / w%, EDTA-2Na · 2H 2 O
5.0-7.0 w / w%, diethanolamine
A composition of 0 to 16.0 w / w% and the remaining amount of water is suitable. The concentration can be doubled by reducing the water for transport or other reasons, but the viscosity of the liquid will increase somewhat. However, freezing at low temperatures can be prevented.
