Description

Technical Field

[0001] The invention relates to the technical field of electrostatic spraying, in particular to a high-voltage electrostatic spraying process for aluminum profiles. Background Art

[0002] Powder high-voltage electrostatic spraying is based on the principle of high-voltage electrostatic corona electric field. The metal spray port and high-voltage electrode needle at the head of the spray gun are connected to the high-voltage negative electrode, and the aluminum profile is grounded to form a positive electrode, so that a strong electrostatic electric field is formed between the spray gun and the workpiece. When the compressed air used as the carrier gas sends the powder coating from the powder supply barrel to the spray port and high-voltage electrode needle of the spray gun through the spray pipe, the corona discharge generated by the high-voltage negative electrode generated by it is connected to the high-voltage negative electrode, and dense negative charges are generated near it, so that the powder carries negative charges and enters the electrostatic field with a high electric field strength. Under the dual effects of electrostatic force and carrier gas driving force, the powder evenly flies to the surface of the grounded aluminum profile to form a powder layer of uniform thickness, which is then heated and solidified to transform into a corrosion-resistant coating.

[0003] Aluminum profiles need to be pretreated before high-voltage electrostatic spraying, and surface moisture needs to be removed after pretreatment. If there is moisture on the surface of the aluminum profile, the powder layer will not adhere well, and defects such as shrinkage holes and pinholes will easily appear on the surface. Profile corrosion will start and spread from then on. Existing aluminum profiles are still easily contaminated by moisture in the air after drying, which reduces their yield rate. Summary of the invention

DETAILED DESCRIPTION

[0018] In order to enable those skilled in the art to better understand the solution of the present invention, the present invention is further described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0019] In this article, the terms "upper, lower, inside, outside" and the like are established based on the positional relationships shown in the drawings. The corresponding positional relationships may also change depending on the drawings, and therefore cannot be understood as absolute limitations on the scope of protection; moreover, relational terms such as "first" and "second" and the like are merely used to distinguish one component from another with the same name, and do not necessarily require or imply any actual relationship or order between these components.

[0020] Example like Figure 1 As shown, a high-voltage electrostatic spraying process for aluminum profiles includes the following steps: S1, pre-treating the aluminum profile 5; the pre-treatment is used to clean the outer surface of the aluminum profile 5, remove the oil stains and oxide layer on the outer surface of the aluminum profile 5, and coat the outer surface of the aluminum profile 5 with a layer of chromium film, which can improve the adsorption rate of the surface of the aluminum profile 5 and the powder, which is beneficial to improve the effect of the finished product.

[0021] S2. Perform a constant temperature treatment on the pretreated aluminum profile 5; immediately maintain the temperature of the aluminum profile 5 after the pretreatment. Generally, the temperature of the pretreated aluminum profile 5 is between 50°C and 60°C. Maintaining the temperature of the aluminum profile 5 in this range can effectively prevent moisture in the air from condensing on the outer surface of the aluminum profile 5 when it is cooled, thereby preventing moisture from adhering to the surface of the aluminum profile 5, affecting the adsorption of powder, and improving the yield rate of high-voltage electrostatic spraying.

[0022] S3, high-voltage electrostatic spraying is performed on the constant-temperature aluminum profile 5; the constant temperature of the aluminum profile 5 is between 50°C and 60°C to effectively prevent moisture in the air from condensing on the outer surface of the aluminum profile 5 when it is cooled, which is conducive to the high-voltage electrostatic spraying.

[0023] S4. The aluminum profile 5 that has undergone high-voltage electrostatic spraying is baked and cured. During the baking and curing process, since the aluminum profile 5 is kept at a constant temperature of 50°C-60°C, the time required for baking and curing can be effectively reduced. The baking and curing temperature is generally around 70°C. Even after the high-voltage electrostatic spraying step, the aluminum profile 5 can be further heated. When entering the baking and curing box, the aluminum profile 5 can be at a higher temperature, reducing the time required for heating, and preventing the charge on the powder from being transferred away by moisture in the air, causing part of the powder to fall, thereby further improving the yield rate of high-voltage electrostatic spraying of the aluminum profile 5. After baking and curing, the aluminum profile 5 needs to be tested to determine the surface quality of the aluminum profile 5, and the aluminum profile 5 with poor surface quality should be eliminated. The means of detection include but are not limited to human eye detection, intelligent image monitoring, etc.

[0024] Specifically, the constant temperature treatment of the aluminum profile 5 can effectively prevent the moisture in the air from condensing on the outer surface of the aluminum profile 5 when it is cooled, thereby preventing the moisture from adhering to the surface of the aluminum profile 5 and affecting the adsorption of the powder, thereby improving the yield rate of high-voltage electrostatic spraying. In addition, the constant temperature treatment effectively reduces the time required for baking and curing, and prevents the charge on the powder from being transferred away by the moisture in the air, causing part of the powder to fall off, thereby further improving the yield rate of high-voltage electrostatic spraying of the aluminum profile 5.

[0025] Furthermore, the above S1 further includes the following steps: S11, treating the surface of the aluminum profile 5; the surface treatment includes a water washing step to preliminarily remove impurities on the surface of the aluminum profile 5; S12, performing weak alkali washing on the surface treated aluminum profile 5; the weak alkali washing includes soaking the aluminum profile 5 in a mixed solution of sodium carbonate and sodium phosphate for 3 to 4 minutes, the pH value of the mixed solution should be maintained at about 8.5-9.5, and the temperature should be controlled at about 50°C-70°C. After soaking, it needs to be rinsed with natural water. The grease on the surface of the aluminum profile 5 can be effectively removed by weak alkali washing.

[0026] S13, performing strong alkali washing on the aluminum profile 5 that has been washed with weak alkali; the strong alkali washing uses a mixed solution of sodium hydroxide and carbonic acid, and the aluminum profile 5 is immersed in the mixed solution of sodium hydroxide and carbonic acid for 3 to 5 minutes. The temperature of the mixed solution of sodium hydroxide and carbonic acid should be controlled at 40° C.-50° C. After immersion, it needs to be rinsed with natural water, and the natural oxide layer on the surface of the aluminum profile 5 is removed by strong alkali washing.

[0027] S14, deoxidation treatment is performed on the aluminum profile 5 after strong alkali washing; some oxides, such as magnesium oxide, still remain on the surface of the aluminum profile 5 after strong alkali washing, and these oxides need to be removed with sulfuric acid or nitric acid. Preferably, the aluminum profile 5 is soaked in a mixed solution of nitric acid and chromium dioxide for 0.5 to 5 minutes at room temperature. After soaking, it is washed with water.

[0028] S15. Perform chromization treatment on the aluminum profile 5 that has been deoxidized; chromization is the most commonly used chemical conversion pretreatment method. The chromized film improves the adhesion between the aluminum metal and the coating and improves the anti-corrosion performance of the coating. In this embodiment, phosphating chromization is adopted, that is, phosphoric acid is used to adjust the pH to 1.7-1.9, and sometimes it may be lower. The chromization temperature is usually 25-30°C. The structure of the green chromized film is a large amount of hydrated chromium phosphate and a small amount of hydrated chromium oxide to form a thicker film layer. The thickness of the chromized film is 0.6-1.5g / m, and the color should be as consistent as possible. After the chromization treatment, the aluminum profile 5 is rinsed with tap water.

[0029] S16, drying the chromized aluminum profile 5. The drying temperature is 50°C-60°C, and the aluminum profile 5 is subjected to a constant temperature treatment after drying.

The aluminum profile 5 is electrically connected to the lifting beam 2 through the contact, and is grounded through the lifting beam 2, so that the aluminum profile 5 forms a grounding electrode. When the aluminum profile 5 moves into the spraying space, the powder is continuously moved from the spraying pipe 9 to the spray gun 8 and sprayed from the spraying port. The distance between the spraying port and the aluminum profile 5 is 10cm-12cm, and the jet pressure is about 0.6MPa. In this embodiment, by arranging the spray gun 8 on both sides of the aluminum profile 5 (and the parameters of the two spray guns 8 are exactly the same), the outer surface of the aluminum profile 5 can absorb the powder well. The clamp extends into the cavity of the aluminum profile 5 to clamp it, which can effectively avoid the generation of clamping points on the outside of the aluminum profile 5 and improve the quality of high-voltage electrostatic spraying.

The vertical moving plate 3 drives the spraying plate 7 to move in the longitudinal direction. When the longitudinal length of the aluminum profile 5 is too long, the spraying plate 7 can be moved in the longitudinal direction to ensure that the outer surface of the aluminum profile 5 can be well coated.
