What is the process of wood polishing? How to polish wood

Polishing is a method of removing scratches and rough uneven parts on the surface of the paint through grinding wax and polishing machine, polishing can grind off the aging paint film of the paint surface, so that the new paint film is produced and restored to brightness. After polishing, waxing or glazing can achieve better results. The main function of car waxing is to prevent rain and acid rain.

Procedure. Polished.

1. Wash the car and remove iron powder and impurities.

2. Inspect all paint surfaces to confirm the degree of defects such as scratches, oxide layers, acid rain spots, dust spots, and orange peels on the paint surface.

3. Cover the area that needs to be painted.

4. Grinding, grinding is the use of abrasives to solve the deep problems that affect the appearance of the paint surface, such as oxide layer, streaks, pollution, and fading.

5. Polishing, polishing is a process after grinding, which is different from the role of grinding. Grinding is to flatten the paint surface to remove deep pollution such as stripes and oxide layers; Polishing is to further smooth the paint surface after grinding, remove the residual stripes of grinding, and the moisturizing ingredients in the polishing agent penetrate deep into the paint surface to make the paint surface show a soft own luster. The polish can also be used alone to remove minor oxidation and dirt.

Waxing. 1. Apply car wax.

1) Use a waxing sponge to dip an appropriate amount of wax into the wax, and evenly apply the wax in a small circle and rotation; The size of the circle is subject to the paint surface without omission in the circle, and each circle covers the previous circle 1 3, and the circle trajectory is in a straight line along the front and rear of the body.

2) Waxing sequence of the whole car: divide the paint surface into several parts, and grind the right half of the body in the order of right front hood - left front hood - right front fender - right front door - right rear fender - trunk lid, and grind the left half of the body in reverse order. Until all lacquer surfaces are waxed without missing a beat.

3) Evenly coat a thin layer of car wax on all paint surfaces, subject to the paint surface obviously covered with a layer of car wax, and the front and rear plastic bumpers of the painted should also be coated with wax.

2. Wipe the wax and polish.

1) 5-10 minutes after waxing, the wax surface begins to turn white, wipe it with the back of your hand, there is powder on the back of your hand, and the painted surface is satisfactory and bright, indicating that the wax has dried. Throw the wax with a soft, dry towel until there is no residual wax on the entire surface.

2) After waxing, thoroughly clean glass, bumpers, trims, tires, steel rims, etc., in the same order as applying wax. Wipe off the wax with a cotton towel and rub the paint with synthetic deerskin until the reflection of the paint is clearly visible.

3. The cleaning sequence is the same as that of applying wax, and the car wax remaining in the cracks on the surface of the car is cleaned to keep the car thoroughly clean.

1. The coarse surface of the log is first polished with an angle grinder, and then sandpaper, and then polished from coarse sandpaper to fine sandpaper in order. You can't come back to the coarse sandpaper after grinding the fine sandpaper. If there are cracks in the log, the cracks can be repaired with 502 glue (instant glue) and sandalwood powder during the sanding process.

2. The sandpaper commonly used in construction includes wood sandpaper, water sandpaper, iron sandpaper, etc. Generally, the putty sanding with partial filling should be made of No. 1 or No. 1 wood sandpaper; The full scraped putty and primer layer should be sandpaper No. 0, and the middle layers of paint film should be finely sandpapered No. 00. Some paint films are dry ground with sandpaper, and friction and heat will cause the paint film to soften and damage the coating film, so water sandpaper should be used for wet grinding.

Before wet grinding, put the water sandpaper in water to soak, then wrap it outside the neatly folded cloth, and then dip it in soapy water to sanding on the paint film, so that the water sandpaper is wrapped outside the cloth, which can expand the area of sanding and use force. In order to improve work efficiency, electric grinders can also be used in large-area grinding construction, generally there are disc type, vibrating type, belt type and drum type.

3. Grinding methods include dry grinding, water grinding, oil grinding, wax grinding and toothpaste polishing. Dry grinding is divided into coarse grinding, flat grinding and fine grinding, of which coarse grinding is generally used to remove wood wool, scars, glue marks and pencil marks and other dirt in the pre-treatment, while flat grinding is usually wrapped in a small wooden block or hard eraser of the abrasive cloth, sandpaper to polish the large plane, so that the leveling effect is better, fine grinding is generally used in scraping putty, sealing paint, color matching and complementary color after the middle layer of each middle treatment, sanding requires careful care. Water grinding is sanding with water dipped in water (or soapy water).

Water grinding can reduce wear marks, improve the smoothness of the coating, and save labor and sandpaper.

5. Then use 120, 320, 400, 600, 800 order to polish, the high mesh sandpaper should completely erase the scratches of the low mesh, otherwise it will fail, the specific steps, as shown in the figure.

If you simply polish, you can run with sandpaper. First use 100 mesh, 200 mesh, 500 mesh, 1000 mesh polishing in turn.

If you want to say that the disc has a pulp. That's a lot more exquisite.

1. First of all, use cotton gloves or silk cloth to rub the surface of the hand beads, so that you can remove the wood powder layer on the surface of the hand beads, which lasts for about half an hour every day, and insists on a week until the fluorescence and transparency are fully revealed. It is forbidden to use your hands directly and stain sweat, water and oil.

2. Complete the above steps, and don't be in a hurry to use your hands to plate. In the next week, we need to wrap the wooden hand beads in a handbag and place them in a cool place, take them out for a week and continue to let the surface of the hand beads oxidize in contact with the air for a week.

3. Start to get started with the beads. When you start to make beads, you should ensure that your hands are clean and dry, and you must not go to beads with sweaty hands. When disbursing the beads, the surface of the beads should be evenly dispensed, so that the beads are slightly hot, especially around the holes of the hand beads.

When you insist on this for half an hour every day for a week, you will find that there will be a slight sticky feeling when you plate the beads, which is the manifestation of the formation of the slurry.

4. After there is slurry, leave it for a period of time.

5. Repeat the steps.

It depends on what kind of toss you want to throw, if you want to be smooth and shiny, it is best to use a sanding machine to wax after sanding! If it is not very demanding, use a sanding machine, and sanding is very natural, the kind of light is very slippery.

1. First use 120 mesh sandpaper for preliminary polishing, and grind it like this, as shown in the figure below

2. Then further polish with 320 mesh sandpaper, as shown in the figure below

3. Then apply lacquer, as shown in the figure below

4. Dry for 48 hours and then use an engraving machine to install a wool wheel to polish.

5. It will be completed after a few more days, as shown in the figure below

Polishing the wood with sandpaper 1000-1500.

Use No. 80 sandpaper to remove dirty things with No. 80 sandpaper, close the edges with No. 360, and burr. The primer is fully ground with 360 sandpaper, then full of sand marks with No. 600, and full ground with No. 1000-1500 sandpaper to polish brightly.

1. Reasonable selection of sandpaper with the same thickness, should not be too coarse, should not use too much of a model, polishing along the wood grain, never vertical and horizontal grinding, otherwise the wood grain will be torn, and the painted furniture will leave permanent flaws.

2. The corners and edges of the polished object should not be sand collapsed, and the action should be light, and the original round or square outline must be maintained. The decorative line must be kept straight and not bent, broken or deformed.

3. When grinding, generally hold down with four fingers and palms, and hold the sandpaper between your thumbs. When polishing furniture with a large area, you can cushion square wood strips and polish along the wood grain. Brush while grinding, because the sand particles of sandpaper are easy to fall off, there is a possibility of grinding the wood grain when rubbing the surface of the object.

4. In addition, the dust and ash after grinding are easy to be embedded in the sideburns, so the dust must be brushed off with a dry brush at any time during grinding, and the surface is smooth and smooth.

5. When there are local bumps and scratches on the plate, the iron should be added with hot water first, and after heating, try to restore the original plane before sanding. If you press the sandpaper with your thumb, index finger and middle thumb, it is only limited to the sand part, and is not suitable for the workpiece with a large area of sand, otherwise the overall plane sand will be uneven, and you can see the concave phenomenon clearly after painting.

1. Wipe with a damp cloth (the surface is a little moist and can't wring out the water) after sandpaper, 2. Polishing the wood after drying, repeat it back and forth about 3 times or 4 times, and finally use the same kind of wood to press and grind again, and wipe it with a cloth a few times in waxing.
