How to choose the aluminum tile trims surface treatment process suitable for humid environments
Corrosion resistance: This is the most important consideration in humid environments. As mentioned earlier, the dense oxide film formed by the anodizing process provides good corrosion protection and is ideal for humid environments. Powder coating also has good corrosion resistance, and its thick coating can block corrosive media, but care should be taken for the quality and integrity of the coating. Although electroplating can provide some protection, the coating is thin and relatively prone to problems in humid environments, unless it is plated with a particularly corrosion-resistant coating such as zinc-nickel alloys.
Abrasion resistance: In wet environments, corner strips may be rubbed due to cleaning or other activities, so some abrasion resistance is required. The oxide film after anodizing treatment has high hardness and good wear resistance. Powder-coated coatings also have some abrasion resistance, depending on the quality of the powder and the thickness of the coating. The plating layer also has good wear resistance, but if there is local wear, exposing the aluminum matrix, it is easy to cause corrosion.
Decorative: Choose according to the overall decoration style of the space where the humid environment is located. Anodizing can provide a variety of colors, and the color is natural, uniform and has good color retention. Powder coating has a wider range of color options and can achieve a variety of special effects, such as matte, high-gloss, matte, etc., and is highly customizable. Electroplating, on the other hand, can present a bright and gorgeous effect, which is suitable for places that pursue a modern and luxurious style.
Cost: Generally speaking, the cost of anodizing treatment is relatively modest. The cost of powder coating varies depending on the quality of the powder and the process requirements, with the cost of unsprayed powder likely to be lower, while the cost of spraying some special effects or high-quality powders will be higher. The cost of electroplating is usually high, especially when plating some precious metals or using special electroplating processes, and the appropriate surface treatment process can be selected according to the budget under the premise of meeting the use requirements.
Environmental friendliness: With the increase in environmental awareness, environmental friendliness is also a factor that needs to be considered. The anodizing process is relatively environmentally friendly and less polluting to the environment. Powder coating does not use organic solvents and meets environmental protection requirements. In the electroplating process, some wastewater containing heavy metals may be generated, which needs to be professionally treated, otherwise it will cause pollution to the environment. If environmental protection requirements are high, anodizing and powder unspraying processes can be preferred.
Maintenance requirements: Choosing a treatment process with low maintenance requirements can reduce the hassle and cost later on. Anodized aluminum tile corners are simple to maintain and relatively easy to clean, but to avoid scratching sheets with sharp tools, simply wipe them down regularly. If there are stains on the surface of the powder coating, one will not damage the coating. The electroplating surface needs to avoid contact with strong corrosive substances, and pay attention to prevent scratches, once the plating layer is damaged, it needs to be repaired in time, otherwise it is easy to rust.
