Aluminum profile powder coating - coating thickness control

Views:102     Author:Alisa      Publish Time: 2018-10-20      Origin:Site Inquire

The most important way to save powder is to control the coating thickness, which directly reflects how much powder is used. The national standard coating thickness should be more than 40 m, and the coating thickness will be too low. If the coating thickness control range is divided in detail, according to the powder characteristics, it can be distinguished from grit powder and polish powder. Generally, the average diameter of new powder is 37-43 micron, the grain size of grit powder is relatively large, and the coverage rate of powder to aluminum profile is high. Therefore, the coating thickness control can take the lower limit, and the powder consumption can be saved to the maximum extent. Small diameter, powder coverage of aluminum profiles is low, should be sprayed as far as possible thick, avoid pan-bottom, especially white powder transparency is high, if the film thickness is not enough, it is easy to pan-bottom blue, so powder should take the upper limit or upper limit.


理想的膜厚控制范围是一个目标也是一个期望,说来容易但是做起来是有一定难度的,为达到这个目标,车间管理人员须重点关注,同时技术人员也要持续督导,并实时监控,要求一线生产员工按工艺操作,通过对各种型号的粉末、铝型材的喷粉工艺的经验积累,不断总结,才能使得技术成熟最终达到我们的期望。

The ideal coating thickness control range is a goal and an expectation, which is easy to say but difficult to do. In order to achieve this goal, workshop managers should pay special attention to it. At the same time, technicians should continue to supervise and monitor the coating thickness in real time, requiring front-line production staff to operate according to the process, through various models. Only by accumulating and summarizing the experience of powder spraying technology for powder and aluminum profiles can we make the technology mature and finally reach our expectations.
