武进不锈钢管换热器标准表面的喷砂处理工作

 

  不锈钢换热管表面的喷砂处理工作:

  On the surface of the stainless steel heat exchange tube sandblasting processing work:

  喷砂就是用压缩空气把石英砂通过喷嘴喷射到预先经过干燥的不锈钢管表面上,靠砂子有力撞击金属表面去掉锈、氧化皮等杂物。

  Sand is the quartz sand with compressed air through the nozzle to advance after drying of the surface of the stainless steel tube, powerful impact on sand metal surface to remove rust, scale and other sundry.

  它能去掉不锈钢管表面的锈、氧化皮、旧的漆层及其他污物。不锈钢管表面经过喷砂变得粗糙又很均匀,能增强油漆层对不锈钢管表面的附着力。所以喷砂在实际施工中应用较广。

  It can remove the rust on the surface of the stainless steel tube, oxide skin, old layers of paint and other dirt. Stainless steel tube surface after sand blasting become rough and very evenly, can enhance the paint adhesion layer on the surface of stainless steel pipe. So the sand has a wide application in the actual construction.

  喷砂用的压缩空气的压力以3.5~5公斤/厘米2为宜。吸砂管在插入砂斗之前要锯一小口,使空气进入便于吸砂。砂粒要求洁净,不应有木屑、石块等杂物,粒径在1~2毫米之间,使用前要炒干。

  Sand blasting with the pressure of compressed air to 3.5 ~ 5 kg/cm2. Sand suction tube before inserting sand bucket to saw a small mouth, to facilitate suck air into the sand. Clean sand requirement, there should be no sawdust, stones and other sundry, particle size between 1 ~ 2 mm, Fried dry before use.

  喷砂前,检查所有设备是否良好,阀门附件应启闭灵活。当压缩空气的压力达到3.5~5公斤/厘米2时,砂粒即被吸出喷射,喷砂方向尽量与风向顺流,喷嘴与不锈钢管表面成70。夹角,并距离金属表面约10~15厘米左右。

  Before sandblasting, check all the equipments are in good condition, the valve attachment should be easy. When the pressure of compressed air is 3.5 ~ 5 kg/cm2, the sand is sucked out spray, sand blasting direction as far as possible and the downstream, nozzle and stainless steel tube surface into 70. Angle, and about 10 ~ 15 cm from the metal surface.

  喷砂处理的优点是操作简单,质量好,生产效率高。缺点是产生大量灰尘,应与其他车间适当隔开,操作人员应戴防护用具如风镜、口罩等。

  Sandblasting processing is the advantage of simple operation, good quality and high production efficiency. The disadvantage is that produce a large amount of dust, should be separated with other wo
