There are a variety of surface treatment methods for plastic profiles. The following are some common treatment methods and their characteristics:
1. Electrostatic spraying
Features: Using the principle of electrostatic adsorption, the coating particles are uniformly adsorbed on the surface of the profile. Uniform coating, strong adhesion, good appearance quality. Can achieve a variety of colors and special effects of the coating, such as metallic texture, matte, highlight and so on.
Advantages:
Improve corrosion resistance and wear resistance of profiles.
Enhance the decorative profile, can be customized according to the needs of different colors and effects.
High construction efficiency, suitable for large-scale production.
Cons:
It has high environmental requirements and needs to be constructed in a clean and dry environment.
The selection and use of coatings requires specialized knowledge, otherwise the coating quality may be affected.
2. Powder spraying
Features: The powder coating is sprayed on the surface of the profile by the spray gun, and then cured into a film at high temperature. Powder coating is environmentally friendly, non-toxic, no solvent volatilization, uniform coating thickness, high hardness, strong corrosion resistance.
Advantages:
Good environmental performance, in line with modern environmental requirements.
The coating has excellent performance, good weather resistance, chemical resistance and wear resistance.
Recyclable to reduce waste.
Cons:
Equipment investment is large, the need for professional spraying equipment and curing furnace.
Color options are relatively limited, not as rich as electrostatic spraying.
1. Decorative film coating
Features: The decorative film with various patterns and colors is pasted on the surface of the profile by hot pressing or gluing. A wide variety of decorative films can simulate the appearance of wood, stone, metal and other materials.
Advantages:
Good decorative effect, can meet different decorative needs.
The construction is simple, fast and the cost is relatively low.
It has a certain protective effect and can prevent scratches and pollution on the surface of profiles.
Cons:
The durability of the film is relatively poor, and problems such as foaming and falling off are easy to occur.
It is sensitive to ambient temperature and humidity and needs to be constructed under suitable conditions.
2. Functional film coating
Features: such as heat insulation film, explosion-proof film, etc., with specific functions. Heat insulation film can reduce heat transfer, reduce indoor temperature; The explosion-proof film can enhance the strength of the profile and prevent splashing when broken.
Advantages:
Give specific function to the profile, improve its performance and use value.
Easy to install, can be installed on existing profiles.
Cons:
The cost is high and the price is relatively expensive.
Different functional membranes need to be selected according to specific needs, and the scope of use is relatively narrow.
Features: Mainly suitable for aluminum profiles, through the method of electrolytic oxidation on the profile surface to form a layer of oxide film. The oxide film has high hardness and corrosion resistance, and can be dyed to obtain different color effects.
Advantages:
Improve the surface hardness and wear resistance of the profile, and enhance its scratch resistance.
Good corrosion resistance, can be used in harsh environments.
Can be dyed, rich and long-lasting color.
Cons:
Only applicable to aluminum profiles, limited application range.
The process is relatively complex and requires professional equipment and technology.
Features: By pressing various patterns on the surface of the profile, increase the decorative and three-dimensional sense of the profile. Embossing can be carried out directly during the profile production process, or it can be processed at a later stage by special equipment.
Advantages:
The unique decorative effect makes the profile more personalized.
Increase the anti-slip performance of the profile and improve the safety of use.
Cons:
Embossing process has higher requirements for equipment and mold.
The choice of patterns is relatively limited, and it is difficult to achieve complex pattern design.
