Abstract
The present invention discloses a kind of method removing enamelled coating, after the method comprises the steps: that workpiece is incubated 10 ~ 20 minutes at-15 ~-30 DEG C, be immersed into ultrasonication 30 ~ 50min in paint-removing liquid, wherein, described paint-removing liquid is containing the sodium hydroxide of 5 ~ 7wt%, the trolamine of 1 ~ 1.5wt%, the dispersing agent MF of 0.5 ~ 1wt%, surplus is water.The inventive method is simple to operate, and paint removal is effective, applied widely, and environmental pollution is few.
Description
Technical field
The present invention relates to a kind of method removing paint layer on surface of workpiece.
Background technology
For preventing iron workpiece from getting rusty, usually at surface spraying one deck rust preventive coating of iron tool, the phenomenons such as enamelled coating is aging because long-term exposure can go out, come off, or workpiece is when keeping in repair, as welding, need the enamelled coating of workpiece surface thoroughly to be removed, again to spray paint or to keep in repair.Existing method of chemical treatment paint remover used is mostly organic solvent type, big for environment pollution.Baking thermal treatment rule easily produces obnoxious flavour, and has a negative impact to workpiece substrate.
Summary of the invention
The object of the invention is to overcome above-mentioned the deficiencies in the prior art, provide a kind of method removing iron tool paint layer from surface.
To achieve these goals, the invention provides following technical scheme:
A kind of method removing enamelled coating, after comprising the steps: that workpiece is incubated 10 ~ 20 minutes at-15 ~-30 DEG C, be immersed into ultrasonication 30 ~ 50min in paint-removing liquid, wherein, described paint-removing liquid is containing the sodium hydroxide of 5 ~ 7wt%, the trolamine of 1 ~ 1.5wt%, the dispersing agent MF of 0.5 ~ 1wt%, surplus is water.
Further, the temperature of described paint-removing liquid is 40 ~ 50 DEG C.
Further, described hyperacoustic frequency is 0.1 ~ 10MHz.
Embodiment
Below the preferred embodiments of the present invention are described, should be appreciated that preferred embodiment described herein is only for instruction and explanation of the present invention, is not intended to limit the present invention.
