2) Placing the preservative solution into the liquid storage tank 2, adding no more than three fourths of the height of the liquid tank each time, and covering the cover;
3) Opening a valve between the liquid storage tank 2 and the immersion liquid tank 3, and controlling liquid to enter the immersion liquid tank 3;
4) According to the length of the U-shaped bottom of the workpiece, the height of a lifting table in the dipping tank 3 is adjusted, and the dip-coating depth is required to ensure that the exposed U-shaped bottom is fully immersed in the preservative solution, preferably less than 5 fins are immersed; dip-coating for a certain time.
5) Horizontally arranging the dip-coated workpiece on a production line or a tool rack to suspend the dip-coated end on a liquid collecting tank, so as to ensure that the dripping liquid can be collected, and the dripping time is not less than a certain time;
6) And placing the workpiece without dripping on an industrial truck, drying for a period of time, and transferring to a terrace frame, wherein a paper separating sheet is needed between the terrace frame and each layer of the workpiece.
It should be noted that it will be apparent to those skilled in the art that various changes and modifications can be made to the present invention without departing from the principles of the invention, and such changes and modifications will fall within the scope of the appended claims.
