Problems solved by technology

Since the existing hardware is basically sprayed with transparent UV oil on the hardware, it is difficult to avoid some small defects (such as sand holes and scratches) on the surface of the hardware that do not affect the use of the product, which reduces the yield of the product.

Embodiment Construction

[0008] The hardware surface spraying process of the present invention comprises the following steps: cleaning→dust removal→spraying primer→spraying topcoat→curing. Each step will be described below.

[0009] Cleaning: The hardware cleaning process includes three processes: ultrasonic wax removal, weak alkaline oil cleaning solution cleaning, dilute acid cleaning and neutralization.

[0010] Dust removal: This process adopts electrostatic dust removal. Firstly, it is sprayed with a high-pressure air gun, and then the surface of the product is irradiated with a high-frequency electrostatic gun to eliminate the static electricity on the surface of the hardware workpiece.

[0011] Spray primer: Let the workpiece soak in the paint pool, turn the workpiece over after taking it out, shake off the excess primer, and finally form a layer of transparent primer with strong adhesion on the surface of the workpiece.

[0012] Spray topcoat: apply matte UV oil evenly on the surface of the h...

Abstract

The invention discloses a hardware surface spraying technology which comprises the following steps of cleaning, dust removing, primer spraying, finishing coat spraying and solidifying. In the spray face coating procedure, matte UV oil of which matte powder has the grain size ranging from 5 microns to 30 microns is used as coating and a high-pressure spraying gun is used for spraying the oil onto the surface of hardware which has passed the primer spraying procedure. After being toasted, the hardware has the finishing coat with the matte effect. The covering power of a paint film layer formed by the spraying technology is good and the paint film layer can cover all sorts of small flaws of the hardware. Thus, the hardware is beautified and has good performances of resisting corrosion and scraping and the like.

Description

technical field [0001] The invention relates to a hardware surface spraying process. Background technique [0002] At present, the existing hardware production process basically includes three major links: stamping forming, cleaning, and coloring. With the differentiation of market demand and increasingly fierce competition, the demand for high-quality hardware is increasing, and the quality of surface treatment, as the most intuitive performance, directly affects customers' attitudes towards products. Since the existing hardware is basically sprayed with transparent UV oil on the hardware, it is difficult to avoid some small defects (such as sand holes and scratches) on the surface of the hardware that do not affect the use of the product, which reduces the yield of the product. Contents of the invention [0003] The object of the present invention is to overcome the disadvantages of the prior art and provide a hardware surface spraying process, which has a simple proces...
