靜電粉末噴涂工藝的特點，技術，節能、安全、污染小。而生產的工業風扇葉片表面涂層具有色澤均勻、耐腐蝕、抗沖擊、附著力強、耐候性好的優點。

      但是在葉片靜電噴涂處理過程中，表面涂層也出現許多質量問題，這是無法避免的問題，所以我們就必須加強生產工藝控制，并且找出問題解決問題，這樣可以保證表面質量不會因靜電涂抹而出現問題，以造成不必要的成本。

      首先我們需要了解粉末噴涂原理：工業風扇葉片靜電粉末噴涂主要采用高壓靜電法。由于工業風扇主要用于高大空間場所，粉末一般采用綜合性能好的熱固性聚酯粉末涂料。其基本原理是噴槍槍體上電極和高壓發生器相聯，產生高壓靜電場，使噴槍周圍空氣發生電暈電離，由于電暈電場的作用，當粉末從噴槍噴出時，粉末粒子與電離空氣粒子碰撞形成帶負電荷粒子，然后隨氣流被送到接地工件上而被吸附。再通過烘烤使粉末涂料固化，從而達到涂裝目的。

Electrostatic powder spraying process features, green technology, energy-saving, safe, less pollution. The surface coating of industrial fan blades produced by our company has the advantages of uniform color, corrosion resistance, impact resistance, strong adhesion and good weather resistance. However, during the process of electrostatic spraying on the blades, many quality problems also appear in the surface coating. This is an unavoidable problem, so we must strengthen the production process control and find out the problems to solve, this ensures that the surface quality will not be affected by electrostatic coating, resulting in unnecessary costs. First we need to understand the principle of powder coating: Industrial Fan Blade electrostatic powder coating mainly using high-voltage electrostatic method. As industrial fans are mainly used in large space, the powder is usually thermosetting polyester powder coating with good comprehensive properties. The basic principle is that the electrodes on the lance body are connected with the high-voltage generator, which generates a high-voltage static electric field and causes corona ionization of the air around the Lance, the powder particles collide with the ionized air particles to form negatively charged particles, which are then transported to the grounding workpiece by the airflow and adsorbed. And then curing the powder coating by baking, so as to achieve the coating purpose.
