Abstract

PURPOSE:To make it possible to release the coating film from a temporary enclosure steel sheet in good working efficiency without discharging any noxious waste liquid by immersing it in a fluid by using a chlorinated solvent fluid composition based on dichloromethane and dichloropropylene. CONSTITUTION:A fluid composition for releasing the coating film from a temporary enclosure steel sheet is formed by mixing a mixture mainly consisting of dichloromethane (A) and dichloropropylene (B) (a suitable mixing ratio of A to B is (70-90):(30-10) with a penetrant for the coating film, such as dimethylformamide, and a chlorinated solvent stabilizer such as triethanolamine as optional components. This compositional is put in an immersion tank 2, a meshed frame 4 having a meshed face 3 is applied to the tank 2, a temporary enclosure steel sheet 6 is mounted on a hanging frame 5 and lifted with, e.g., a fork lift truck, and the sheet 6 is hung down together with the hanging frame 5 into the immersion tank 2 to immerse it in the release fluid composition.

The above composition beam is mainly composed of two chlorinated solvents, methylene dichloride and propylene dichloride, and the ratio is (70~
90): The range of (30 to 10) is suitable. Dimethyl sulfoxide, methanol, dimethylformamide, etc. do not necessarily need to be added, but they are effective in promoting penetration of the chlorinated solvent into the coating film, and are added as appropriate depending on the composition of the coating film. Triethanolamine is effective as a stabilizer for chlorinated solvents, and other stabilizers can also be used. Water floats on the surface of the composition liquid and is effective in suppressing evaporation of the composition liquid. This composition liquid can be used repeatedly by collecting and removing the peeled coating film with a mesh frame, but the solvents absorbed by the coating film must be replenished from time to time to maintain the desired composition.

This stripping device has a hanging frame that can load and suspend multiple steel plates in a dipping tank, making it efficient to immerse a large amount of steel plates in a tank in a short period of time. Good. When using the stripping composition according to the present invention, most of the coating film will peel off inside the tank, but the peeled coating film can be collected by a mesh frame and discharged outside the tank, so steel plates can be continuously immersed. This makes it possible to repeatedly remove the coating film. Therefore, in combination with this stripping composition, this stripping device can significantly improve the efficiency of coating stripping.
