The correct choice of color aluminum coil should consider the natural environment, operating environment, design period, and structural characteristics of the building to select the matching steel grade, specification, coating and coating. Architects, project owners and processing parties think about the safety performance of buildings (impact resistance, earthquake resistance, fire resistance, wind pressure resistance, snow resistance), residential performance (waterproof, sound insulation, heat insulation), durability performance (pollution resistance, durability , appearance persistence), economy (low cost, easy processing, easy maintenance, easy replacement) and so on. For color aluminum coil manufacturers, these properties should be converted into color aluminum coil performance as a color aluminum coil factory and guaranteed. The performance requirements of color aluminum coils mainly include mechanical properties (tensile strength, yield strength, elongation), coating properties (coating variety, coating thickness and coating adhesion) and coating properties (coating type, color, gloss, durability, durability, processability, etc.).
Color aluminum coil: wind resistance, impact resistance, snow resistance, earthquake resistance, etc. are all related to the mechanical properties of the material, of course, it is also related to the waveform of the color profiled steel plate, the thickness of the steel plate, the span, and the purlin distance. If you choose a suitable color aluminum coil The coil is matched with the appropriate profiled steel plate design, which can not only meet the safety factor of the building but also reduce the project cost. The durability, processing performance and appearance persistence of materials are largely determined by the durability of coatings and coatings.
There is a coating on the surface of the color aluminum coil, and the coating plays an important role in "anti-corrosion". Let's talk about how this anti-corrosion is sorted out.
Brushing can use a variety of coatings, as long as it is not a coating with poor leveling, this step mainly allows the coating to penetrate into the pores of the metal surface, which can enhance the metal adhesion.
(2) Scratch coating
In this step, the requirements are high, and the paint with high liquid purity and high viscosity should be used, and attention should be paid to the common defects of the paint (cracking, falling off, rolling, etc.).
(3) Dip coating
Dip coating is a traditional coating method, which is easy to cause air pollution. Do not use volatile coatings.
(4) Spray coating
Flow coating is to spray the paint on the surface of the coating. Although the operation is simple and the production efficiency is high, the consumption of spray coating is larger than that of dip coating, which will cause problems of safety and impregnation, so we must pay attention.
The advantages of spraying are (the thickness of the coating is uniform, the appearance is smooth, and the production efficiency is high), and the air pollution is not small.
