一、前言粉末静电喷涂是金属表面保护的一种先进工艺,在国内有一定优势,主要是因为它没有溶剂损耗和污染,材料利用率高,一般采用双旋风和布袋式两级回收装置,回收率达98%以上。这种涂敷方法,在多种场合已代替了液体涂料涂装工艺。它的涂敷范围由过去只做防腐发展到装饰性涂层。二、粉末静电喷涂的特点粉末静电喷涂和其它喷涂,有着截然的不同。粉末静电喷涂是利用高压静电和压缩空气,将粉末
I. INTRODUCTION Powder electrostatic spraying is an advanced technology of metal surface protection and has certain advantages in China mainly because it has no solvent loss and pollution and high material utilization rate. Generally, it adopts double cyclone and bag type two-stage recovery devices to recover Rate of 98% or more. This coating method has replaced the liquid coating process on many occasions. Its coating range has only been preservative developed to decorative coatings in the past. Second, the characteristics of electrostatic powder coating Electrostatic powder coating and other spray, with a completely different. Powder electrostatic spraying is the use of high-pressure electrostatic and compressed air, the powder
