安徽省金属垃圾桶厂家烤漆工艺流程

金属垃圾桶烤漆前外表预处理目的是为了得到杰出的涂层,由于以上的冲压件在制造、加工搬运、保存期间会有油脂,氧化物锈皮,灰尘,锈及腐蚀物等在外表上,合肥垃圾桶厂家若不将其去除直接影响到涂膜的性能,外观等,大大降低野外运用防锈蚀能力。所以前处理在涂装工艺中占有极为重要的地位。通过脱脂、除锈、磷化等工序后的工件外表清洁、均匀、无油脂,它对整个涂层质量、涂层运用寿命、涂层外观等均有着重要影响。

烤漆时,将风门调至烤漆位置,热风循环,烤房内温度迅速升高到预订干燥温度(55℃—60℃)。风机将外部新鲜空气进行初过滤后,与热能转化器发作热交换后送至烤漆房顶部的气室,再通过第2次过滤净化,热风通过风门的内循环作用,除吸进少数新鲜空气外,绝大部分热空气又被持续加热利用,使得烤漆房内温度逐渐升高。当温度到达设定的温度时,燃烧器主动停止;当温度下降到设置温度时,风机和燃烧器又主动敞开,使烤漆房内温度保持相对稳定。最终当烤漆时间到达设定的时间时,烤漆房主动关机,安徽金属垃圾桶烤漆完毕。
