摘要: [目的]分析木门旋杯式静电喷涂表面漆膜厚度及均匀性的影响因素和作用机制,为旋杯式静电喷涂技术在木门涂装领域的应用提供理论基础。[方法]利用数值计算方法,建立木门旋杯式静电喷涂漆膜厚度理论模型,分析喷枪垂直方向移动速度、木门进给速度、喷枪水平方向移动行程和喷枪垂直方向移动行程、喷枪间距等工艺参数对于木门表面漆膜厚度及均匀性的影响规律。[结果]喷枪垂直方向移动速度对漆膜厚度平均值的影响较小,但是对漆膜厚度标准差(均匀性)有一定影响,且漆膜厚度标准差与喷枪垂直方向移动速度不呈线性关系;木门进给速度对漆膜厚度平均值的影响较大,但是对漆膜厚度标准差的影响较小;随着喷枪水平方向移动行程增加,漆膜厚度平均值先增加后逐渐趋于稳定,漆膜厚度标准差先减小后逐渐趋于稳定;喷枪垂直方向移动行程对于漆膜厚度平均值及标准差均有较大影响;喷枪间距对漆膜厚度平均值的影响较小,但是对漆膜厚度标准差有一定影响,且漆膜厚度标准差与喷枪间距呈周期性变化关系。[结论]木门旋杯式静电喷涂漆膜厚度理论模型能够预测木门静电喷涂后表面的漆膜厚度及其标准差,可为木门旋杯式静电喷涂设备运行参数的优化提供理论指导。

Abstract: [Objective] The purpose of this paper is to study the film thickness and its uniformity of wooden door after rotary cup type electrostatic spraying.[Method] The theoretical analysis model of film thickness and its uniformity of wooden door after rotary cup type electrostatic spraying are built based on numerical calculation method in this paper. The effects of feed speed of wooden door, distance between spray guns, vertical direction movement speed, horizontal direction movement stroke and vertical direction movement stroke of spray gun on the film thickness and its uniformity of wooden door are mainly studied.[Result] Analysis result show that vertical speed of spray gun has a little effect on the average film thickness of wooden door, but has a certain influence on standard deviation (uniformity) of film thickness and there is not a linear relationship between them; wooden door feed speed has an obvious effect on the average film thickness of wooden door, but has a little effect on standard deviation of film thickness; the average film thickness of wooden door increases firstly and then tends to be stable with horizontal stroke of spray gun, standard deviation of film thickness decreases firstly and then tends to be stable with horizontal stroke of spray gun; vertical stroke of spray gun has an obvious influence on both the average film thickness and standard deviation of film thickness; distance between spray guns has a little effect on the average film thickness of wooden door, but has a certain influence on standard deviation of film thickness and the relationship between them is periodic.[Conclusion] The numerical calculation model of film thickness and its uniformity of wooden door after rotary cup type electrostatic spraying can predict the average film thickness and standard deviation of film thickness of wooden door, which can provide theoretical guidance for the operation parameters optimization of the rotary cup type electrostatic spraying equipment.
