 大型储罐如何做防腐除锈工作呢?一般来讲储油罐,各种储罐都是先焊接好外壳体,检查压力容器设备的安全性能等,然后在进行除锈处理,传统的除锈方法手工打磨较慢,清理效果不佳,所以一般都是用干式喷砂机打砂除锈,由于干式喷砂会产生一定的扬尘,工作场地受限制,所以目前较环保的方法为储罐内干喷砂除锈,外壁水喷砂除锈。

 
干式喷砂就是常说的喷砂,是以空压机的高压压缩空气为动力,将磨料(石英砂、金刚砂或河沙)通过专用的喷头(喷嘴)、以很高的速度喷射到工件表面,借助磨料的冲击力、切削力及摩擦力,高效的去除涂层和锈层。
 
水喷砂除锈跟干式喷砂有所不同,水喷砂是在罐中加砂与水混合,在通过压缩空气,将水与砂一起喷出,由于水的存在可以抑制98%的粉尘污染,并且操作时无火花等安全隐患!在通过加入防锈粉或防锈剂可以延长油罐表面生锈的时间!更有利与后期的喷涂!
How to do anticorrosion and derusting work for large storage tank? Generally speaking, for oil storage tanks, all kinds of storage tanks are welded to the shell first to check the safety performance of pressure vessel equipment, and then derusting treatment is carried out. The traditional derusting method is slow in manual grinding, and the cleaning effect is not good, so the dry sand blasting machine is generally used to sand and derusting, because the dry sand blasting will produce certain dust, and the working site is limited, so it is more environmentally friendly at present The methods are dry sand blasting in the tank and water sand blasting in the outer wall.
 
 
 
Dry sand blasting is often called sand blasting. It takes the high pressure compressed air of the air compressor as the power to spray abrasive (quartz sand, emery or river sand) to the surface of the workpiece through a special nozzle (nozzle) at a high speed. With the help of the impact force, cutting force and friction force of abrasive, the coating and rust layer can be removed efficiently.
 
 
 
Water sand blasting is different from dry sand blasting. Water sand blasting is to mix sand and water in the tank, and spray water and sand together through compressed air. Because of the existence of water, 98% of dust pollution can be suppressed, and there is no spark and other safety hazards during operation! By adding antirust powder or antirust agent, the time of oil tank surface rust can be prolonged! More favorable with later spraying!
