摘　　要：静电喷涂技术在木门制造中的应用才刚起步,木门经过透明底漆的静电喷涂后,其表面电阻大小将直接影响后续面漆的静电喷涂工艺。因此,本文以常用的3个树种装饰薄木饰面木门作为研究对象,对其经过静电喷涂后的表面电阻进行实测分析,探究湿膜、干膜状态下木门表面电阻的影响因子及影响规律。结果表明:静电喷涂后,不管是横纹方向,还是顺纹方向,黑胡桃、金丝柚与沙比利3种装饰薄木饰面木门的表面电阻皆随湿膜厚度的增加而减小,量级为10~7?;当木门表面的涂层完全凝固干燥后,不管木门表面的装饰薄木材种如何,其横、顺纹方向表面电阻骤然增大,达到G?量级。Electrostatic spraying technology has just been applied in the manufacture of wooden doors. The surface resistance of wooden door after electrostatic spraying process of transparent primer could affect the quality of electrostatic spraying of top finish directly. Therefore, three kinds of decorative veneer are chosen for decoration of wooden doors, which are taken as research object in this paper. The surface resistance of wooden door after electrostatic spraying process of transparent primer is studied. The influence factors and influence law of surface resistance of wooden door in wet film and dry film state are studied. The results are shown as follows; the surface resistance of wooden door after electrostatic spraying process of transparent primer is decreased with the thickness of wet film, the order of magnitude is 107Y2; the surface resistance of wooden door after electrostatic spraying process of transparent primer is greatly increased when the wet film is changed to dry film, the order of magnitude is GΩ.
