在桥梁护栏上喷涂粉末时，请注意吊具的导电性，吊具上的涂层不应太厚。如果太厚，可以通过集中焚烧去除设备上的涂层;因为工件很重，所以必须进行设计。
When spraying powder on the bridge guardrail, please pay attention to the conductivity of the spreader, the coating on the spreader should not be too thick. If it is too thick, the coating on the equipment can be removed by centralized incineration; because the work piece is heavy, it must be designed.
预烘烤的目的是去除工件上残留的水分，其次是确保将一定厚度的粉末涂料更好地附着在工件表面，第三步是确保均匀地加热工件尽快加快固化过程（欢迎免费注册，登陆中国沥青网（沥青在线）行业门户网址www.sinoasphalt.com，免费发布供求，免费发布产品，免费发布企业动态）。一般预烘烤温度为80-140℃。
The aim of pre-baking is to remove the residual moisture on the workpiece, then to ensure that a certain thickness of powder coating better adhere to the surface of the workpiece, the third step is to ensure that the uniform heating of the workpiece as soon as possible to speed up the curing process. The pre-baking temperature is 80-140 °C.
对于桥梁护栏产品，根据其特点，采用自动喷枪和手动喷枪辅助喷涂相结合的方法，目的是实时监控喷涂粉的质量，确保产品质量的稳定。通常，纯多酚粉末涂料的固化条件为200℃，10min，并通过调节加热炉的温度和链速来保证固化温度和时间。
According to the characteristics of the bridge guardrail, the method of combining automatic spray gun with manual spray gun is adopted to monitor the quality of the powder in real time and ensure the stability of the product quality. In general, the curing condition of pure polyphenol powder coating is 200 ° C, 10 min, and the curing temperature and time are ensured by adjusting the temperature of heating furnace and chain speed.
桥梁护栏粉末喷涂用冷空气干燥。在干燥过程中，检查工件。对于下垂，起泡，打底和打孔等允许的缺陷，可用丙酮等稀释粉末涂料。对缺陷表面进行处理或喷涂，利用余热固化需要修复的主要缺陷。根据涂膜的厚度选择不同的处理方法。通常，有直接加载和重新喷涂，机械抛光以及用脱模剂处理的三种方法。
