. Market situation: Due to equipment and process reasons, only large aluminum material factories can do it, and the quality is very guaranteed. It is more common in the surface treatment of large-scale profiles, and the "appearance ratio" on home improvement doors and windows is not high;

Electrophoresis:
.Technology: The roast chicken process of "electrophoresis" is similar, except that the "coating sauce" is applied after it is out of the oven, mainly to make it easier to preserve - the anodized (colored) product is used as the anode, and aluminum or stainless steel is used as the cathode. , placed in a heat-curing acrylic transparent resin solution, under the action of an external electric field, the negatively charged paint particles move toward the product, thereby forming a layer of adhesive paint film on its surface;
.Features: The weather resistance is better than that of anodizing, the surface is smooth, and the appearance is brighter and more gorgeous than anodizing, but the paint film is easy to scratch;
Quote: same as anodizing;

Powder Coating:
.Process: Roast chicken (profile) is colored by brushing particle seasoning method - powder spraying, also known as electrostatic spraying, is based on the physical phenomenon of electrophoresis, so that the atomized paint particles are negatively charged on the high-voltage electric field, and electrostatically Under the action of the field, it is directionally flowed to the surface of the positively charged profile, thereby attaching to form a firm film;
.Features: more color options, strong weather resistance;
.Quote: Compared with the above two, the powder coating equipment and process are more "operable". At the same time, because of the "high degree of customization and high color selectivity", it is more suitable for home improvement doors and windows, and various spraying plants are very suitable. It is the surface treatment method with the highest "appearance rate" for home improvement doors and windows;

Fluorocarbon spraying:
.Technology: The roast chicken (profile) is brushed with particle seasoning and the method is more advanced - based on polyvinylidene fluoride, it is synthesized with metal powder and has a metallic luster. In order to obtain coatings with excellent performance, two-layer and three-layer processes are generally used;
.Features: Equivalent to an upgraded version of "powder coating", the quality and durability will be higher, and the color is very close to "powder coating";
Quote: same as above;

Wood grain transfer:
.Process: Paste a layer of permeable film printed with wood grain pattern on the surface of the qualified aluminum material after powder electrostatic spraying, and then vacuumize to completely cover the permeable film on the surface of the profile, and then transfer the ink on the permeable film by heating, Infiltrate the powder layer to achieve the effect of wood grain appearance;
.Characteristics and market conditions: The appearance of wood grain is favored by certain groups of people, representing all kinds of sun rooms, but its weather resistance is not recognized, and it is more suitable for interior profile decoration.
