What should be paid attention to in the construction of reciprocating spraying equipment?

2020-04-09

1. The hardener and thinner must be correct

Incorrect proportions of hardener and thinner will affect the effect of the paint.

2. Good primer

Regardless of spraying, solid color baking varnish, silver primer baking varnish, good quality should be used to increase adhesion and gloss.

3. Stir evenly

Regardless of the paint and the manufacturer, it is important to mix them evenly, especially those containing silver powder.

4. The air pressure should be appropriate

The nozzle pressure of the reciprocating spraying equipment is very ambitious when it is maintained at 40-50 pounds. Too much or too small pressure will affect the spraying effect and cause damage.

5. Check tools and working environment before painting

The oil in the air compressor of the reciprocating spraying equipment must be released first. Completely clean, check the spray booth, ventilation filter, and clean the floor of the spray booth.

6. Clean appearance

The surface of the spray must be cleaned with water, it is oily, and the wax should be used to make the oil. The metal surface after the new welding or rust removal should be treated with epoxy resin anti-rust primer to prevent rust.

7. The correct sanding method

Do not use sandpaper too hard, use finer sandpaper as much as possible.

8. Use high-quality thinner

Don’t make economic calculations on thinners. Use matching thinners. The paint can be of very high quality. Using cheap thinners can save a few dollars, but it will pay more time and energy; using high-quality thinners will make the work better. Handy.

9. Good ventilation

10. The spraying environment of reciprocating spraying equipment must be clean

Keep the distance between the spray gun and the object at 15-20 cm, each spraying distance is 5-10 minutes, each product has different construction instructions, such as: hardener mixing, spraying distance, available time, etc.

The reciprocating spraying equipment can only open one, or only one or a few of them can be opened when multiple spray guns are working together, not all normal operations. The power of the air compressor is not possible, perhaps the volume of the air storage tank is not possible, increase the power of the air compressor may use a larger volume air storage tank. It is also possible that the size of the main air pipe is not available, so add the size of the main air pipe appropriately.
