Suzhou Liujin Machinery Equipment Co., Ltd. gives you a brief introduction to electrostatic spraying equipment

In the era of rapid development, modern science and technology change with each new day, a dazzling array of coating products on the market, to the spraying industry has brought new development, today Suzhou Liujin Machinery Equipment Co., Ltd. to teach you how to choose the right spraying equipment, to make our spraying work more energy efficient and perfect, first of all, we must understand the classification of spraying equipment and their respective characteristics. Fluid spraying equipment can generally be divided into five categories: air spraying equipment, high-pressure airless spraying equipment, air-assisted airless spraying equipment, high-efficiency low-voltage spraying equipment, electrostatic spraying equipment, today we briefly introduce electrostatic spraying equipment.

Electrostatic spraying equipment: electrostatic spraying can be combined with air and mixed gas spraying, and integrate their advantages into a new spraying method. Add DC high voltage between the grounded workpiece and the spray gun, it will produce an electrostatic field, with negative charge paint particles sprayed to the workpiece, after colliding with each other evenly deposited on the surface of the workpiece, those scattered near the workpiece of the coating micro-material is still in the scope of electrostatic field, it will surround the workpiece, so sprayed to all the surface of the workpiece. This spraying method is generally suitable for spraying fences, pipelines, small steel structures, steel pipe products, hardware, spectacle frames, jewelry and other geometric shape complex, small surface area of the workpiece, can easily and quickly spray paint to every place of the workpiece, can reduce paint overspray, save paint. The transfer efficiency of the coating is as high as 60-85% and its atomization is very good, and the thickness of the coating film is uniform, which is conducive to the improvement of product quality. In addition, on wood furniture, electrostatic spray gun can also achieve good electrostatic encircling effect, especially suitable for chairs, coffee tables, car wood products and other workpieces. There are many advantages of electrostatic spraying, but it has certain requirements for the viscosity and conductivity of the coating, not all coatings are suitable for electrostatic spraying, and the investment in equipment is also large.
