Embodiment Construction

[0017] Below in conjunction with the examples, the specific implementation of the present invention will be further described in detail. The following examples are used to illustrate the present invention, but are not intended to limit the scope of the present invention.

[0018] The wood product color repairing process method of the present invention comprises the following steps successively:

[0019] a. Primer sanding: The primer sanding before spraying must be correctly operated according to the requirements, sanding along the grain, sanding in place, and no defects such as sand leakage, sand marks, uneven sand, uneven sand road, and sand deformation;

[0020] b. Check whether there is air leakage in the spray gun: adjust the air pressure, the air pressure of the empty gun is 3-4Mpa, and the air pressure of spray paint is 0.5-0.8Mpa;

[0021] If the air pressure is too high, there will be no paint in the middle of the atomization zone of the spray gun. After the paint is ...

Abstract

The invention relates to a processing method for wood working of furniture industry. A wooden article shading process sequentially comprises the following steps of: a, sanding primer; b, checking whether a spray gun has an air leakage phenomenon; c, adjusting the amount of a paint; d, controlling air velocity in a spray room; e, preparing before spraying; f, spraying base color; g, shading and polishing; and h, performing secondary shading according to the step g. According to the wooden article shading process, the main means of increasing air pressure of an air gun, spraying air pressure, air velocity in the spray room, spraying pressure and distance of a spray gunpoint is adopted; and a paint film on the surface of a wooden article is rich, smooth and attractive by adopting the secondary shading method.

Description

technical field [0001] The invention relates to a treatment method for wood processing in the furniture industry, in particular to a wood product color repairing process. Background technique [0002] The existing wood product color repairing process is to control the air gun air pressure at 2-3Mpa during the color repairing process, the painting air pressure at 0.3-0.5Mpa, the wind speed in the spray booth at 0.2-0.4m / s, and the spraying pressure at 2-3Mpa. 3kg / cm 2 , the nozzle of the spray gun is 15-20cm away from the surface of the wood product. This method of operation cannot completely make the surface of the wood product repair the desired purpose, mainly due to the air pressure of the air gun, the air pressure of the spray paint, the wind speed in the spray booth, the spray pressure and the distance from the nozzle of the spray gun to the wood product. The surface process parameters are unreasonably controlled, especially in the color correction process of white too...
