Embodiment Construction

[0028] like figure 1 Shown, a kind of wrought iron product surface antirust treatment process, it comprises following process step:

[0029] (1) According to the design requirements, the pre-fabricated galvanized workpiece;

[0030] (2) Use AL-15 special solution, open the pool to soak the workpiece for 3-5 minutes, remove the impurities on the surface of the workpiece, and ensure that the galvanized layer on the surface of the workpiece does not fall off, and increase the surface bonding force and weather resistance of the workpiece;

[0031] (3) Using the activated water treated by the permalinkite small molecule agglomeration processor provided by Beijing Wanjiaduole Technology Co., Ltd., the workpiece is sprayed and cleaned twice in two pools. The cleaning time is 4 minutes. The HP value is controlled at 7.5-8.5;

[0032] (4) Use the degreasing liquid prepared by activated water and sulfonic acid that has been treated with small molecules, divide the degreasing liquid in...

Abstract

The invention relates to a surface rust preventing treatment process for iron art products and provides a novel spraying line production technique. The surface rust preventing treatment process is characterized in that traditional phosphating is replaced by ceramic treatment on a spraying flow production line, common urban tap water is replaced by small cluster water with activity in each washing link during spraying, and common water base degreasing fluid is replaced by small cluster water base degreasing fluid. Compared with traditional phosphating, the method uses non-phosphorus ceramic treatment for pretreatment in prior to nano spaying, and accordingly adhesive force between coating and metal can be increased evidently, and corrosion-resistant time of metal can be prolonged.

Description

technical field [0001] The invention relates to an antirust treatment process for the surface of iron art products. Background technique [0002] All kinds of wrought iron products, including assembled wrought iron balcony railings, pay special attention to the unity of functionality and aesthetics, that is, to be durable and safe, attractive and always new, and the basis of all these is weather resistance, first of all, assembly Weather resistance of component surfaces. Iron products with a non-weather-resistant surface are neither attractive nor durable, and of course they are not safe and environmentally friendly. For this reason, a considerable number of wrought iron product manufacturers carry out corresponding spraying treatment on the surface of the product through manual operation, and use phosphating as a primer before spraying treatment to improve the adhesion between the coating and the base material and the surface corrosion resistance. This is a very effective...
