How to make ribs in car painting 10, how to make ribs in car painting

The specific steps of automobile painting ribs are as follows:

1. Inspection. The car comes through sheet metal, first check the place to be done, look at the reflection from the side, there are uneven places and sheet metal places, first use 150 sandpaper to polish, the grinding range exceeds the uneven part of about five centimeters, do not use 60, 60 is too coarse, it has an impact on the back process.

2. Fill the ash, make the first ash on the grinding place, pay attention to the place where the iron is exposed, first scrape a thin sheet metal ash and then scrape the putty. Do not exceed the grinding range, generally about two centimeters away from the grinding edge is the best, convenient and fast grinding, it is worth mentioning that beginners should fill the place slightly higher point, and then scrape the gray edge thin, skilled hands can be ignored.

3. Grinding, finish the first ash, make sure that the pit has been filled before starting to grind, the water mill starts 15 minutes after the ash is filled, don't wait for the ash to dry thoroughly, it is so difficult to grind. Dry grinding must wait for the ash to dry. It is recommended that beginners learn water mills first.

First use 150 sandpaper to grind out the edge of the ash, and then smooth it as a whole, if the ash is too thick, polish it at 60, but don't grind it to the ash edge, grind it with 60 and then use 150 again, look at the ash edge, and the previous grinding is smooth, and the ash is flat.

4. Polishing the paint surface, grinding the paint surface to judge first, to make sure that there will be no color difference sprayed, use 800 to polish, estimate the color difference, use 1500 to polish, 1500 polishing must be polished through, that is, there is no bright place on the paint surface after polishing, and there is a bright representative of no grinding.

5. Fill the sand hole and sandpaper road, and use 150 to polish the place and the small reflective pit left by the polishing paint surface, and then scrape it with putty, this time the ash should be pressed and scraped hard, and the filling range should cover all the 150 grinding range. This ash can only be sanded when it is dry, and it can be sanded only after it is scratched with a fingernail until the scratches turn white.

6. Polish, polish the ash that fills the sand hole and sandpaper road with 240, and then use 400 sandpaper to polish the smooth place.

7. Spray primer or scrape red ash, fill the ash place last, whether spray primer or scrape red ash, the edge must be pressed and ground with a board, so that there is no ash mark when sprayed out, with 800 or 1000 polishing, 600 is not recommended, 600 sandpaper road is too large, the impact is perfect, the primer is polished smooth and smooth, and the red ash is worn as thoroughly as possible, that is, only the sandpaper road and the sand hole and the gray edge are a little red and gray after the basic grinding, and the rest is putty ash. If the red ash is left in a large area, it will cause paint stripping and blistering. If you have to leave a large area of red ash, you should bake it with a baking lamp, polish it after cooling, and then bake it with a baking lamp after polishing, which can increase the adhesion of red ash and reduce the chance of paint stripping or blistering.

8. Wash the car, clean the parts that need to be painted and the adjacent parts.

9. Blow water to paste newspaper or blow water paste to cover paper, blow water to dry all the edge seams, do not stick the sticker to the edge at one time, leave a little bit of the edge of the place, add a piece of paper tape welt, and tear off the paper tape immediately after painting, so that there will be no edge when sprayed out.

This, technical work, paint is done well depends on scraping putty, of course, the angle and diameter are not very easy to do, without a few months of work is not good...

Hello The steps of the automotive painting interface are as follows: select a dust-free space. Use 3m sandpaper or 2000 sandpaper to polish off the varnish at the joint position.

Spray the topcoat, being careful not to spray into the interface area. Spray varnish, cover the spray topcoat position for the first time, and grind off the varnish interface position for the second time, and leave a gap of about five centimeters. Sprinkle the interface with water and dispose of the interface.

The automotive spraying industry still has great potential, on the one hand, everyone is now pursuing personalization, on the other hand, there are more and more vehicles, if you do a good job, the benefits are very objective, and it is also a very hot technology.

Hello, you can take this approach and that's when we're doing this. You can put a layer of tape on top of us, and then apply a few more layers. Just make that height.

Then the other half of the words directly, scrape the putty. After scraping, remove the tape from the top. Then go to scrape, so that it is relatively straight, a little better.

Especially for us who don't have a strong sense of direction.

All the tendons are composed of two sides, so make the tendons first and do the two noodles well, and the tendons will come out. Straight is to use masking paper paste, and then hang ash and polish ash after pasting, it will naturally be straight.

It is easy to compare it with a steel ruler, or to pull an auxiliary line with paper tape.

With soft scraping--- rib line can be scraped twice, scraping separately on both sides of the rib county.

Personal experience: If you want to be fast, you need to simplify the process, and the putty should be scraped up to three times.

Strive to do it once and perfect it once.

The simpler and faster the base processing, the constant repetition of work is the cause of delays.

Use paper tape to paste the amplitude of the stem, scrape the putty, hang it around the stem, and then grind it much better, be careful.

Sticking with tape paper is the best way for beginners If it's not too troublesome, I also saw someone draw the edge and grind it, mainly to strive for perfection, and then I give the most ordinary diameter grinding method Like the front fender tire is not a very long diameter like this kind of warp is the easiest, you can **putty, first grind the upper part of the path, don't care below To grind along the warp, the rubber plate should be flattened, the coarse sand above is almost grinding and grinding the bottom, this time the warp is almost the same, and then use fine sand to repair it a little. Depending on whether this is good or not, you can use water or degreaser.

Glued with paper tape, divided into upper and lower scraping and grinding putty.

Tape the edges with thick edges.

If you don't have strength, then first blind typing, find strength by feeling, and then polish the tape, and then draw it.
