Embodiment

[0027] Embodiment: a kind of electrostatic color uniform painting method of the present invention, it comprises the following steps:

[0028] (1) A spray booth control unit is set to control the wind speed in the spray booth;

[0029] (2) An electrostatic automatic painting unit is set to control the working state of the electrostatic automatic painting gun so as to achieve the set painting effect;

[0030] (3) An automatic hanger unit is set, so that the interval between the workpiece hangers to be painted is set reasonably, and the speed of the conveyor chain used to suspend the hangers is reasonable;

[0031] (4) In the spray booth, an electrostatic automatic spray gun is used to spray paint on the workpiece to be painted suspended on the hanger, and the paint is well attached to the workpiece through the electrostatic effect.

[0032] In the step (1), it includes a wind speed control unit and a humidity control unit.

[0033] In the described step (2), the automatic pain...

Abstract

The invention discloses a static even-color painting method comprising the following steps of: setting a painting chamber control unit for controlling air speed in a painting chamber; setting a static automatic painting unit for controlling the working state of a static automatic painting gun to ensure that the static automatic painting gun achieves a set painting effect; setting an automatic hanger unit to ensure that workpiece hangers to be painted are reasonably arranged at intervals and the velocity of conveying chains for suspending the hangers are reasonable; and painting workpieces to be painted, hung on the hangers in the painting chamber by using the static automatic painting gun so that paints are attached to the workpieces well by a static effect. The static even-color paintingmethod has the advantages that (1) a paint film has the characteristic of evenness, good leveling property and obviously improved orange-peel phenomenon; (2) the distinctness of image (DOI) and glossiness of the paint film are improved, and a PGD (a unit of the DOI) value can be improved by 0.1-0.3; (3) by adopting static automatic painting, the emission of a volatile organic solvent is effectively reduced to relieve environmental pollution of painting; and (4) the painting efficiency is improved and paint is saved.

Description

technical field [0001] The invention relates to the field of surface painting, in particular to an electrostatic color uniform painting method. Background technique [0002] In the prior art, painting technology develops rapidly, and electrostatic spraying technology is widely used at present, and the design of electrostatic color uniform spraying method is crucial to the use of product spraying quality. If the design and mastering are not proper, no matter how well the individual equipment is made, the quality of the sprayed products cannot be guaranteed. The surface coating of the coated product is not uniform, the electrostatic enveloping effect is not good, and the utilization rate of the paint only reaches 30%. Contents of the invention [0003] The invention provides an electrostatic color-leveling paint spraying method. Through the implementation of the method, the surface quality of product spraying can be improved, and the utilization rate of the paint can reach ...
