发布时间:2015-12-4 10:23:10 浏览次数:558

喷砂用压缩空气冷却装置及油水分离器必须经过处理,以保证干燥、无油分离器汤;必须定期清洗。


喷嘴到基体钢材表面距离100至300毫米,而应当,喷砂前一定要喷砂部位进行隔离保护。


喷气方向和基体钢材表面法线夹角为15至30°°。


喷砂除锈后,下一道工序进行前,如遇下雨或其他的基体钢材表面的环境状况的时候,要把施工条件后,用压缩空气吹干表面的水分干燥后施工,如果必须重新喷砂磨料不降低。降低血了。


喷砂时喷嘴(不要久留,喷砂作业部分工作必须避免的。然而,一次喷射面积太大了,应该考虑涂装或热喷涂工艺和表面预处理工序之间的时间间隔。

这样,喷枪喷射部位不应该采取手工或动力工具除锈。


Air cooling device and oil / water separator with compressed air shall be treated, in order to ensure that the dry and non oil separator soup; must be cleaned regularly.
Spray nozzle to the surface of the substrate material from 100 to 300 mm, and should be, must be part of the sand blasting before the separation of the site to protect.
The jet direction and the surface normal of the base steel are 15 to 30 degrees.
After sandblasting derusting, before a procedure, in case of rain or other steel matrix surface state of the environment to the construction conditions, construction with compressed air dry the surface moisture after drying, if must re blasting abrasive is not reduced. Reduce blood.
When blasting nozzle (not long, part of the work must avoid the blasting operations. However, an injection area is too large, should consider the time interval between coating or thermal spray process and surface pretreatment process.
In this way, the spray parts should not adopt manual or power tool cleaning.
