Embodiment 1

[0018] Embodiment one, a kind of metal powder spraying process that reduces workpiece surface coating particle, comprises the following steps:

[0019] S1: Place the workpiece in the pool, use 60 to 80 degrees Celsius hot water to clean the outer wall of the workpiece, and clean the oil and dirt on the outer wall of the workpiece;

[0020] S2: Observe whether there is corrosion on the surface of the workpiece. If there is corrosion and the corrosion is relatively light, use an acidic lotion to clean the workpiece at 70 degrees Celsius. Each liter of the acidic lotion contains 50 milliliters of sulfuric acid, 5 mL thiourea and 20 mL sodium alkylsulfonate;

[0021] S3: Use sodium bicarbonate solution to clean the workpiece after pickling, and rinse it with clean water three to five times to observe whether there are bubbles and cavities in the galvanized layer on the surface of the workpiece. If the galvanized layer has voids, repair the voids on the surface of the workpiece by...

Embodiment 2

[0028] Embodiment two, a kind of metal powder spraying process that reduces workpiece surface coating particle, comprises the following steps:

[0029] S1: Place the workpiece in the pool, use 60 to 80 degrees Celsius hot water to clean the outer wall of the workpiece, and clean the oil and dirt on the outer wall of the workpiece;

[0030] S2: Observe whether there is corrosion on the surface of the workpiece. If there is corrosion and the corrosion is serious, use an acidic lotion to clean the workpiece at 80 degrees Celsius. The acidic lotion contains 70 milliliters of sulfuric acid and 10 milliliters of sulfur per liter of solution. Urea and 40 ml of sodium alkylsulfonate;

[0031] S3: Use sodium bicarbonate solution to clean the workpiece after pickling, and rinse it with clean water three to five times to observe whether there are bubbles and cavities in the galvanized layer on the surface of the workpiece. If the galvanized layer has voids, repair the voids on the surfa...

Abstract

The invention discloses a metal powder spraying process capable of reducing coating particles on the surface of a workpiece. The process includes the following steps that S1, the workpiece is placed in a pond, the outer wall of the workpiece is washed with hot water with the temperature being 60-80 DEG C, and oil stains and dirt on the outer wall of the workpiece are removed; and S2, whether the rusting phenomenon exists on the surface of the workpiece is observed, if the rusting phenomenon occurs, an acid washing solution is used for cleaning the workpiece at the temperature of 70-80 DEG C, and the acid washing solution is prepared from sulfuric acid, thiourea, alkyl sodium sulfonate and water. According to the metal powder spraying process, oil stains and dirt on the surface of the workpiece is removed, so that subsequent treatment on the workpiece is facilitated; the acid washing solution is used for removing rust, the workpiece can be protected against further oxidation and rusting, and the strength of the workpiece is improved; and the bubble area on the surface of the workpiece is polished and subjected to hole repairing, the actual spraying area of the workpiece is reduced, metal powder is saved, and the cost is lowered.

Description

technical field [0001] The invention relates to the technical field of metal powder spraying technology, in particular to a metal powder spraying technology for reducing coating particles on the surface of workpieces. Background technique [0002] Metal powder coatings refer to various powder coatings containing metallic pigments. Because metal powder coatings can show a bright and luxurious decorative effect, they are very suitable for spraying indoor and outdoor objects such as furniture, accessories and cars. In terms of spraying process, the current domestic market mainly adopts the dry mixing method, and the bonding and fixing method is also used internationally. The above-mentioned metal powder coatings are mainly sprayed with spray guns, but when spraying the used workpieces or corroded workpieces, The amount of metal powder consumed is higher than a brand new workpiece. Contents of the invention [0003] Based on the technical problems existing in the background ...
