Problems that should be paid attention to when choosing paint
Let's talk about the basic knowledge of mechanical paints; mechanical paints generally protect the appearance and decoration of these two aspects of the role, there are many types of paint. According to the usage, it can be divided into mechanical paint, iron paint, equipment paint, machine tool paint. There is a special kind of mechanical paint: mechanical paint, it is a light-cured unsaturated resin, after light polymerization into full resin. The paint is the hardest and most weathering resistant in all kinds of mechanical paints. The output power is more than 10 times higher than that of PU and PE. But the price of production process is higher. Air painting process is usually used for mechanical paint processing.
Painting on metal surfaces of mechanical paints must be done through multiple processes. Usually remove oil, rust and phosphating before entering the painting process.
Metal spraying is divided into three types: air spraying, electrostatic spraying and magnetic spraying.
There are two kinds of mechanical lacquer materials, one is etch type and the other is baking type. Etching material spraying and coloring plays a role in grinding machinery, its artistic role is many, mechanical paint color to thousands of kinds. Self-drying and quick-drying mechanical paint and spraying should be completely cured by high temperature baking, similar to the effect of cloisonne in Chinese ceramics. It is also divided into clear and unclear two kinds, mechanical paint its construction process can also be used silk printing process, but the concentration of mechanical paint is a little thicker.
Mechanical paint and electrostatic powder spraying principle is the same, the difference is that aluminum must be selected coating type, together with the appearance does not lubricate, through oxidation treatment of mechanical spraying adhesion is the best. But the cost is higher, there is a kind of mechanical appearance called electrophoresis process treatment, after this process also need to be sprayed off treatment. Such paints are usually made of mechanical PU or PE and other mechanical paint. Different process requirements are matched with different mechanical paints for spraying.
