[0028] The technical solutions in the embodiments of the utility model will be described clearly and completely in combination with the drawings in the embodiments of the utility model. Obviously, the described embodiments are only some of the embodiments of the utility model, not all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by those skilled in the art without creative labor belong to the scope of protection of the utility model.

[0029] In order to make the above-mentioned purposes, features and advantages of the utility model more obvious and easy to understand, the utility model will be further described in detail in combination with the drawings and specific embodiments.

[0030] Multiple spraying is a technique of applying paint on the surface of an object multiple times. In industrial production or some delicate hand-painting processes, a single spraying often cannot meet the requirements for the thickness, uniformity, color effect, and other aspects of the coating. Multiple spraying is to gradually achieve the ideal coating state by applying paint on the surface of the object multiple times. For example, in the process of painting cars, multiple spraying is used to achieve a bright, durable, uniform, and thick paint surface.

[0031] The main purposes of multiple spraying:

[0032] 1. Improve appearance. Multiple spraying can make the color more saturated and uniform. For example, in furniture painting, the first spraying may only serve as a primer to color the wood surface and fill in small pores. Subsequent spraying can make the color more pure and better reflect the texture of the wood. Special visual effects can be achieved. For example, some metal products can be sprayed with multiple layers of transparent paint or paint with different gloss levels to create a complex appearance effect such as gradient, level, or pearl.

[0033] 2. Enhance coating performance. Increase the thickness of the coating. For products that require corrosion resistance or wear resistance, such as outdoor facilities and mechanical parts, a single spraying may not be enough to provide adequate protection. Multiple spraying can increase the thickness of the coating and improve its protective ability. Improve the adhesion of the coating. Each layer of paint can provide a better adhesion base for the next layer, making the entire coating system more firmly attached to the surface of the object being coated.

[0034] Specific operation procedures and precautions:

[0035] 1. Surface treatment of the object being coated is crucial. Before multiple spraying, the object's surface needs to be cleaned, sanded, and degreased to ensure a smooth and clean surface, which ensures good adhesion of each layer of paint. For example, before multiple spraying of rust-resistant paint on metal products, the surface rust and dirt should be removed with sandpaper, and then the surface oil should be cleaned with organic solvent.

[0036] 2. The spraying parameters of each layer of paint need to be adjusted according to the type of paint, the material and shape of the object being coated, and other factors. These parameters include spraying pressure, distance between the spray gun and the object's surface, spraying speed, etc. For example, when multiple spraying of plastic toys, the distance between the spray gun and the object's surface can be slightly closer during the first spraying of primer to ensure good adhesion of the primer, and the distance can be appropriately increased during the subsequent spraying of topcoat to prevent sagging.

[0037] After each layer of paint is sprayed, it needs to be dried according to the requirements of the paint product manual. This can be natural drying, or it can be oven drying in a specific temperature and humidity environment. For example, some water-based paints need to be dried for 2-3 hours in a well-ventilated environment after the first layer is sprayed before the next layer can be sprayed.

[0038] 3. After each layer of spraying is completed, the quality of the coating is checked to see if there are defects such as sagging, orange peel, pinholes, etc. If problems are found, they should be repaired in a timely manner. After all the spraying is completed, some surface treatment such as polishing can be done to further improve the appearance and performance of the coating.

[0039] Multiple spraying is widely used in many industries such as automobiles, furniture, machinery manufacturing, etc., which can effectively improve the appearance quality and protection performance of the products.
