It is necessary to make good progress before the mirror aluminium plate is painted. Substrate pretreatment technology comes into being with the production of coating technology. It serves the coating technology and lays the foundation for the preparation of excellent coating. All the substrates of color coated aluminium mirror sheet will leave some grease and lubricant on the surface during the production process, of course, in operation. Other substances may be adhering to the transporting process. If these oils and adhesives can not be removed, it will affect the coating and use of the aluminum sheet. In addition to these, chemical treatment is required on the clean substrate surface to form a stable conversion film.
The color coated aluminium mirror sheet is a composite material formed by coating one or more layers of organic coatings on the surface of the aluminium substrate after the color-coated machine. It has the advantages of both aluminium sheet and organic material. It not only has the advantages of high mechanical strength, good toughness, easy processing and moulding of the aluminium sheet, but also has the advantages of high mechanical strength, good toughness, easy processing and moulding. Mechanical polymer coatings have good decorative, coloring and corrosion resistance, and can be easily processed by bending, blanking, deep drawing and welding.
For the use of color coated aluminium mirror sheet, in order to enable better development, such production is also a better progress.
