Abstract
The invention relates to a low-pressure spraying method for a local wound on an automobile. The low-pressure spraying method comprises the following steps of step one, processing a roll line; step two, spraying primer paint, repairing the wound, leveling a spraying surface, and calculating the needed paint spraying thickness; step three, spraying a first transparent paint layer under low pressure by using a paint spraying gun; step four, spraying a nanometer powder coating layer under the lower pressure; step five, rapidly spraying a second transparent paint layer under the lower pressure after step three is completed; step six, spraying a third paint layer under low pressure, and expanding the third paint layer to the surface of the roll line; step seven, carrying out baking processing; step eight, repeatedly implementing the steps from step three to step seven for twice; step nine, spraying a fourth transparent paint layer under low pressure, and locally covering an original paint surface; step ten, carrying out the baking processing. According to the low-pressure spraying method for the local wound on the automobile, provided by the invention, the bouncing of paint can be reduced, and the adhesive force of the paint can be enhanced; the atomization is reduced, dust in the air cannot be carried, and the spraying surface is clearer; small-distance spraying is carried out, and the paint surface effect is good.
Description
Technical field
The present invention relates to automobile finish recovery technique field, be specially a kind of automobile local trauma low pressure spraying method.
Background technology
The spray gun that the spraying of conventional vehicle lacquer painting uses adopts hyperbar to carry out spraying operation, and air pressure generally clings to air pressure at 2.8-3.5.Under hyperbar large discharge, paint rebounds in a large number, and paint is atomized in a large number, has a strong impact on the health of environment and workman, and the utilization rate of whole process paint only has 35%-45%, and material cost is too high, and in spraying process, dust is easily flushed to lacquer painting with air-flow.Have influence on the repairing effect of car body lacquer painting.
Summary of the invention
For prior art Problems existing, the invention provides a kind of automobile local trauma low pressure spraying method.
The technical scheme that the present invention takes is, build a kind of automobile local trauma low pressure spraying method, described method step is as follows,
The first step, roll line process.
Second step, spray-applied primer, wound reparation, spray-coating surface is levelling, calculates required spray paint thickness.
3rd step, uses paint sprayer low pressure spraying ground floor celluloid paint.
4th step, low pressure spraying Nano-Powder Coatings.
5th step, after the 3rd step completes, rapid low pressure spraying second layer celluloid paint.
6th step, low pressure spraying third layer is painted and expands to roll line face.
7th step, baking process.
8th step, repeats implementation step the 3rd step to the 7th step 2 times.
9th step, low pressure sprays the 4th layer of celluloid paint and the former lacquer painting of local complexity.
Tenth step, baking process, completes car body local trauma low pressure paint spraying.
Further, during described car body spray paint, the jet opening distance car body surface distance 100-140mm of paint sprayer.
Further, the pressure of the spraying of paint sprayer is 0.8-1.4
baratmospheric pressure.
Further, described paint sprayer flow of paint is 60-140L/min.
Automobile local trauma low pressure spraying method provided by the present invention, spray gun air pressure is low to moderate 0.8-1.4 bar, reduces paint bounce-back, increases PASS, reduces paint bounce-back; Spraying air-flow is low to moderate public liter/min of 60-140, and reduce atomization, can not be with koniology, spray plane is cleaner; Lance head distance spray plane 100-140mm, small distance sprays, and lacquer painting is effective.
Detailed description of the invention
Set forth a lot of detail in the following description so that fully understand the present invention.But the present invention can be much different from alternate manner described here to implement, those skilled in the art can when without prejudice to doing similar popularization when intension of the present invention, therefore the present invention is by the restriction of following public specific embodiment.
Below in conjunction with embodiment, the specific embodiment of the present invention is described further.
embodiment 1
In the present embodiment, structure of the present invention is described in detail.
A kind of automobile local trauma low pressure spraying method, described method step is as follows,
The first step, roll line process.
Second step, spray-applied primer, wound reparation, spray-coating surface is levelling, calculates required spray paint thickness.
3rd step, uses paint sprayer low pressure spraying ground floor celluloid paint.
4th step, low pressure spraying Nano-Powder Coatings.
5th step, after the 3rd step completes, rapid low pressure spraying second layer celluloid paint.
6th step, low pressure spraying third layer is painted and expands to roll line face.
7th step, baking process.
8th step, repeats implementation step the 3rd step to the 7th step 2 times.
9th step, low pressure sprays the 4th layer of celluloid paint and the former lacquer painting of local complexity.
Tenth step, baking process, completes car body local trauma low pressure paint spraying.
Further, during described car body spray paint, the jet opening distance car body surface distance 100-140mm of paint sprayer.
Further, the pressure of the spraying of paint sprayer is 0.8-1.4
baratmospheric pressure.
Further, described paint sprayer flow of paint is 60-140L/min.3, transmission efficiency more than 65% is painted.
1, the present invention selects nano-paint, and paint molecular structure is tight, is applicable to ultralow pneumatic spraying of the present invention, can not produces sagging.
2, spray gun adjustment air pressure 0.8-1.4 of the present invention
barair pressure, oil pump capacity 60-140L/min, lance head distance spray plane 100-140mm.Such minimizing atomization, adds transmission efficiency, reaches the object that environmental protection economizes paint.
3, to carry out small size locally sprayed in the present invention, and decrease the surface of a wound and expand, the process of locally sprayed roll line, makes new and old lacquer painting completely the same simultaneously.Although the present invention with preferred embodiment openly as above; but it is not for limiting the present invention; any those skilled in the art without departing from the spirit and scope of the present invention; can make possible variation and amendment, the scope that therefore protection scope of the present invention should define with the claims in the present invention is as the criterion.
