Guardrail electrostatic spraying after brushing fluorocarbon paint process is how?

Powder electrostatic spraying process: first of all, the steel surface treatment, such as degreasing, surface conditioning, hot dip galvanizing, cleaning, phosphating, drying. This series of pre-process, mainly play a clear rust, in addition to impurities, not only remove the steel rust prone to causative factors. Also let the surface of the steel produced by the zinc layer and phosphate film, zinc layer to protect the steel is not easy to be corrosion and rust, phosphate film so that the surface of the steel for powder coating, powder adhesion is stronger. Steel pre-processing is completed, the use of equipment consisting of spray guns, spray cups and spraying high-voltage power supply, the use of high-voltage electrostatic field so that negatively charged paint particles around the electric field in the opposite direction to do directional movement, and then be adsorbed on the surface of steel to be coated. High-performance electrostatic spraying machine is used to complete the spraying, using electrostatic shielding to achieve the effect of powder adhesion. The powder coating on the steel surface is heated to the specified temperature (180℃-220℃) and kept warm for a corresponding period of time, so as to make it melt, leveling, curing, so as to get the surface effect of the guardrail products we want. The use of electrostatic spraying is very broad, not only in the fencing industry, likewise in the automotive industry, metal products industry. It is also widely used in the insulation mention industry, such as wood, rubber and so on. Its surface color is gorgeous, smooth, can achieve special layer and feel, not easy to fall off, but also has excellent weather resistance. It realizes the assembly line production in the guardrail industry, which improves the quality of the products and the investment of labor cost. Paint spraying process: The use of paint spraying process also needs to be pre-treatment of steel, the general process of pickling (or shot blasting) - degreasing - phosphating - washing - natural drying - putty - spray primer - spray topcoat - natural drying. The traditional medium paint and top coat line adopts hand-operated air spraying technology, generally adopts non-line operation, is sensitive to the external climate, and cannot be constructed on rainy days, which is suitable for multi-species and less mass production. ? Spray paint process and origin requirements of the flexibility to be better than powder coating, but the effect of spraying is relatively rough, the layer of short weather resistance, excess paint flow down non-recyclable to become an environmental pollutant. Fluorocarbon spraying is a kind of electrostatic spraying, is also a liquid spraying method, called fluorocarbon spraying, Hong Kong called curium oil. Belong to the high-grade spraying, so the price is higher, in foreign countries have long been applied. Fluorocarbon spraying has excellent resistance to color fading, frost resistance, corrosion resistance to atmospheric pollution (acid rain, etc.), strong UV resistance, strong crack resistance and the ability to withstand harsh weather conditions, is not as good as the general coating. Plastic spraying is a surface treatment method of spraying plastic powder on parts. Plastic spraying is also commonly referred to as electrostatic powder coating coating, its treatment process is the 1980s since the international use of a more common metal surface treatment of decorative technology. The technology and ordinary spray paint surface treatment, compared with the advantages embodied in the process of advanced, energy efficient, safe and reliable, color and lustre and so on.
