Architects, project owners and processors consider the safety performance of buildings (impact resistance, earthquake resistance, fire protection, wind pressure resistance and snow resistance), residential performance (waterproof, sound insulation and heat insulation), durability (pollution resistance, durability and appearance persistence), economy (low cost, easy processing, easy maintenance and easy replacement), etc. For color aluminum coil manufacturers, these properties as color aluminum coil manufacturers should be transformed into color aluminum coil properties and guaranteed. The performance requirements of color aluminum coil mainly include mechanical properties (tensile strength, yield strength, elongation), coating properties (coating type, coating thickness and coating adhesion) and coating properties (coating type, color, gloss, durability, processability, etc.).

Among them, wind resistance, impact resistance, snow resistance and earthquake resistance are related to the mechanical properties of the data. Of course, they are also related to the waveform, thickness, span and purlin distance of the color profiled steel plate. If the appropriate color aluminum coil is selected and matched with the appropriate profiled steel plate design, it can not only meet the safety coefficient of the building, but also reduce the project cost. The durability, processability and appearance persistence of materials are largely determined by the durability of coatings and coatings.
There is a layer of coating on the surface of color aluminum coil, which plays an important role in "anti-corrosion". Let's talk about how the anti-corrosion is sorted out.
(1) Brush coating
Various coatings can be used for brushing, as long as they are not coatings with poor leveling performance. This step mainly allows the coating to penetrate into the pores on the metal surface and strengthen the metal adhesion.
In this step, it is required to use high-point coatings with high liquid purity and high viscosity, and note the common defects (cracking, falling off, rolling, etc.) of the coatings.
(3) Dip coating
Dip coating is a traditional coating method, which is easy to cause air pollution. Remember not to use volatile coatings.
(4) Drench coating
Drenching coating is to drench the coating onto the surface of the coating. Although the operation is simple and the production efficiency is high, the consumption of drenching coating is greater than that of dip coating, which will produce safety and dip dyeing problems. We must pay attention to it.
Spraying has the advantages of uniform thickness, smooth appearance and high production efficiency, and air pollution is not small. There is a layer of coating on the surface of color aluminum coil, which plays an important role in "anti-corrosion".
