油漆應用于熱噴涂技巧及方法的介紹

  油漆用于熱噴涂工業始于20世紀初,最早由瑞士蘇黎市的M.U.Schoop博士于1910年發明,1912年研制成功線材火焰噴涂槍,1916年研制出實用型電弧噴槍。

  

  油漆線材火焰噴涂時至今還在應用。它是采用氧-乙炔燃燒作為熱源,噴涂材料為線材的熱噴涂方法。

  

  噴槍通過虹吸作用分別引入乙炔、氧氣和壓縮空氣,乙炔和氧氣混合后在噴嘴出口處產生燃燒火焰。

  

  送絲輪帶動線材連續地通過噴嘴中心送放火焰,在火焰中受熱熔化,壓縮空氣經空氣帽形成錐形高速氣流,將熔化的線材霧化成細微的顆粒,在火焰和高速氣流的推動下,熔融顆粒噴射到經過預處理的基材表面看形成涂層。

  

  涂料線性火焰噴涂的涂層結構為明顯的層狀結構,涂層有較多的孔隙和氧化物加渣,對于鋅和鋁涂層來說,其孔隙率在10%~15%在噴涂過程中,壓縮空氣的流量和壓力必須保持恒定,否則送絲忽快忽慢,會嚴重影響絲材的熔化效果。
