Three common methods of rust removal of sprinkler tank

As we all know, the sprinkler tank in the water for a long time under the penetration of the bubble is easy to produce rust, if not timely, it may affect the service life of the sprinkler tank. So, what are the rust removal methods of sprinkler tank?
A, sprinkler tank sand blasting method
Sand blasting is one of the most commonly used methods to remove rust in the sprinkler tank. The operator has a pressure fan, sand blasting machine, etc., the quartz sand should be screened and washed first. This method has the advantages of high quality rust removal and good surface roughness. But its disadvantage is that it will produce a lot of dust pollution environment.
Two, sprinkler tank cycle cleaning method
If it is a small sprinkler, according to the total capacity of small sprinkler tank 10 ~ 30% injection of special paint withdrawal agent (dichloromethane, ethyl acetate composition), paint withdrawal agent penetration, swelling, make the old coating and sprinkler tank wall peeling, and then soak for about 30 minutes, and then continuous cycle for about 2 hours, pay attention to the pH value to maintain at 1.5±0.2. Then discharge the cleaning fluid, clean the small sprinkler tank with water circulation; Then use rust remoster (mainly hydrochloric acid, corrosion inhibitor, etc.) for pickling, the time is generally 15 minutes. Need to remind you that after rust removal to passivation for at least 4 hours, the final sprinkler tank inside the paint refresh.
Three, sprinkler tank high-pressure water rust removal method
The use of ultra-high pressure water cleaning machine to remove the rust on the inner wall of the sprinkler tank, after a few minutes, and then rinse with water. This method can remove all kinds of chemical impurities on the tank wall gap and metal surface, so that the original steel plate body has no damage. After cleaning the sprinkler water tank wall can find all holes and pit corrosion hidden dangers, so as to effectively ensure the quality of the sprinkler water tank rust removal. The advantage of this method is that it can quickly penetrate and peel off, decompose the accumulated scale, rust and other mineral deposits, effectively inhibit the corrosion of steel, copper and other metals, and has no effect on most coating surfaces. And no concentrated hydrochloric acid, concentrated sulfuric acid risk, pungent taste, safe use, high efficiency of rust removal.
Here we need to remind you that the sprinkler tank cleaning process, chemical cleaning French acid, please do not contact the skin for a long time. When using, pay attention to avoid splashing into eyes. If accidentally splashing into eyes or adhering to skin, rinse immediately with water.
