5 big advantage Airless sprayer spray electrical equipment with high-pressure piston pump paint pressurized to 3000PSI (210kg / cm) were obtained while spraying paint through high-pressure high-pressure hose to the gun delivery, release the pressure through a nozzle to form spray, so that the wall surface to form a dense coating. Because the coating does not require compressed air atomization, so called airless spray. It has the following advantages: First, a high coating efficiency. 500-1200 square meters per hour spraying efficiency is more than 10 times a second, excellent surface quality traditional drum construction. Spray coating formation, brilliance, compact, no brush marks, roller marks, and particles. Third, to extend the life of the coating. Airless paint particles make deep wall voids, so the film is also a mechanical occlusion wall, enhance paint adhesion, and prolong life. Fourth, easily overcome corners, gaps and uneven hard brush fifth site, saving coatings. Brush coating thickness is uneven, typically 30-250 microns spotlights spraying, paint spraying downlight low utilization, without gas spraying readily obtained a coating thickness of 30 microns, 20-30% relative save paint. Coating production line workshop is a great energy and power skills programs selected directly affects the work of the workshop costs. Coating production line roller painting skills programs should be based on practical situation, choose an adequate supply, the more economic power. Pre-treatment equipment for heating power is more economical steam or hot water. Drying power for more economical waste gas treatment is natural gas or coal gas. Costs related to the company's life, reduce costs touched many. Engineering solutions is the source, accounting costs from the source. Painting skills, diligence and frugality, must reduce the cost of coating production lines. Down spraying, spraying sand hung hardware appliances, spraying sand by Dongguan Hong Hardware Electric Co.
