The specific embodiment
Below with reference to the accompanying drawings, describe one embodiment of the invention in detail.
Fig. 1 is the square frame process chart of the cleaning method of lacquering used of elimination automobile scar of expression an embodiment of the present invention.
Fig. 2 represents utilizing cleaning method of lacquering of the present invention to eliminate the position of scar, the coating part of applying coatings, the transparent coating agent of high concentration and the transparent coating agent of low concentration.
Cleaning method of lacquering of the present invention shown in Figure 1 comprises following operation: scar grinding, applying coating, the transparent coating agent coating of high concentration, the transparent coating agent coating of low concentration, applicator surface drying and polishing.
The scar grinding step is that the peripheral part to scar grinds the operation that face around making becomes smooth burnishing surface, adopt directly scar is partly carried out the lapping mode that sand papering is handled, it is better that perhaps the coating solid material carries out the lapping mode of sand papering.Be preferably in scar part coating solid material, carry out sand papering and handle, scar is partly ground.At this moment the solid matter of Shi Yonging is well-known, and its representational material is gypsum, clay etc.
Scar partly ground make it become burnishing surface, remove and grind after the foreign matter that produces, carry out painting process.Painting process is utilization and needs the coating of the automobile same color of processing to apply by common coating method.At this moment as shown in Figure 2, painted in scar part 1 and near position thereof after grinding.
After the coating of coating finishes, utilize common coating method coating not contain or contain the transparent coating agent of high concentration of few relatively diluent, make the coating scope be no more than the applying coating face 2 of Fig. 2, perhaps a little surpasses the marginal portion of applicator surface 2.Transparent coating agent is that industry personage knows, commercially available product.
