靜電粉末(mo)噴涂工藝的(de)特點(dian)，技術(shu)，節能、安全、污(wu)染小。而生產的(de)工業風扇葉片表面涂層具有色(se)澤(ze)均(jun)勻、耐(nai)腐蝕、抗沖擊、附著力強、耐(nai)候性好的(de)優點(dian)。

      但是(shi)在(zai)葉(xie)片靜電噴涂(tu)處理過程(cheng)中，表(biao)面涂(tu)層(ceng)也出現(xian)許多質(zhi)量問(wen)題(ti)(ti)，這是(shi)無(wu)法避免的問(wen)題(ti)(ti)，所以(yi)我們就必(bi)須加(jia)強生(sheng)產工藝控制(zhi)，并且找(zhao)出問(wen)題(ti)(ti)解決問(wen)題(ti)(ti)，這樣可以(yi)保證表(biao)面質(zhi)量不會因(yin)靜電涂(tu)抹而出現(xian)問(wen)題(ti)(ti)，以(yi)造(zao)成不必(bi)要的成本。

      首(shou)先我們需要(yao)了解粉(fen)(fen)末(mo)噴(pen)涂(tu)原理：工(gong)業風扇葉片靜電(dian)(dian)粉(fen)(fen)末(mo)噴(pen)涂(tu)主(zhu)(zhu)要(yao)采用(yong)高壓靜電(dian)(dian)法。由(you)(you)于(yu)(yu)工(gong)業風扇主(zhu)(zhu)要(yao)用(yong)于(yu)(yu)高大空間(jian)場所，粉(fen)(fen)末(mo)一般采用(yong)綜(zong)合性(xing)能好的(de)熱固性(xing)聚酯粉(fen)(fen)末(mo)涂(tu)料。其(qi)基本原理是噴(pen)槍(qiang)槍(qiang)體上電(dian)(dian)極和高壓發生(sheng)器相(xiang)聯，產生(sheng)高壓靜電(dian)(dian)場，使噴(pen)槍(qiang)周圍空氣發生(sheng)電(dian)(dian)暈(yun)電(dian)(dian)離，由(you)(you)于(yu)(yu)電(dian)(dian)暈(yun)電(dian)(dian)場的(de)作用(yong)，當粉(fen)(fen)末(mo)從噴(pen)槍(qiang)噴(pen)出時，粉(fen)(fen)末(mo)粒(li)子(zi)(zi)與電(dian)(dian)離空氣粒(li)子(zi)(zi)碰撞形(xing)成(cheng)帶(dai)負(fu)電(dian)(dian)荷粒(li)子(zi)(zi)，然后隨氣流被送(song)到(dao)接(jie)地工(gong)件上而被吸附。再通過烘(hong)烤使粉(fen)(fen)末(mo)涂(tu)料固化，從而達到(dao)涂(tu)裝目的(de)。

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.
