  • 静电粉末喷涂工艺的特点,技术,节能、安全、污染小。而生产的亚博体育APP官方yabo亚博体育苹果下载叶片表面涂层具有色泽均匀、耐腐蚀、抗冲击、附着力强、耐候性好的优点。

          但是在叶片静电喷涂处理过程中,表面涂层也出现许多质量问题,这是无法避免的问题,所以我们就必须加强生产工艺控制,并且找出问题解决问题,这样可以保证表面质量不会因静电涂抹而出现问题,以造成不必要的成本。

          首先我们需要了解粉末喷涂原理:亚博体育APP官方yabo亚博体育苹果下载叶片静电粉末喷涂主要采用高压静电法。由于亚博体育APP官方yabo亚博体育苹果下载主要用于高大空间场所,粉末一般采用综合性能好的热固性聚酯粉末涂料。其基本原理是喷枪枪体上电极和高压发生器相联,产生高压静电场,使喷枪周围空气发生电晕电离,由于电晕电场的作用,当粉末从喷枪喷出时,粉末粒子与电离空气粒子碰撞形成带负电荷粒子,然后随气流被送到接地工件上而被吸附。再通过烘烤使粉末涂料固化,从而达到涂装目的。

    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.
