This product has the function of strong rust removal and inhibit corrosion efficiently, can dissolve scale, cement dirt, minerals, limestone and rust. It’s especially suitable for cleaning the scale of cooling water system. It can permeate and dissolve carbonate and other sediments, and other insoluble substances will be decomposed and detached during the reaction.

a) Economic efficiency: it is a concentrated product, which can be diluted according to the actual working conditions, with low average cleaning cost.

b) High efficiency: rapid rust removal can quickly remove rust spots on the metal surface. It also penetrates to dissolve carbonate and other sediments (such as scale) and breaks down other insoluble substances during the reaction.

c) Environmentally friendly: there is no smoke phenomenon similar to concentrated hydrochloric acid and risk of use.

1. Method Of Using

a). Heat exchanger and water system descaling: Appropriate dilution ratio should be selected according to the degree of descaling and cleaning speed. First inject clean water into the circulation system, and then gradually add ES-122 into the circulation tank for circulation cleaning. use the test paper to measure the pH value every 15-30 minutes, If the pH value is exceeding than 1, add an appropriate amount of ES-122 to keep the pH value below 1. After a continuous cycle of about 4-6 hours, if the pH value does not change within 1 hour, indicating that the reaction is over, the cleaning waste solution can be neutralized and discharged. The residual cleaning liquid in the equipment was thoroughly cleaned with a slightly alkaline aqueous solution, and then washed repeatedly to rinse the residue in the system.

b). When the cement thin layer is cleared, spray ES-122 with plastic spray bottle, rub and rub with a brush (steel ball), and rinse thoroughly with water. The filth on marble should dip with sponge the ES-122 that USES water to dilute several times is swabbed, rinse clean with water next.

C). To remove the corrosion on the metal surface, soak it in ES-122 original solution, and then neutralize and flush the cleaned metal surface with plenty of water. ES-221 or ES-212 can be used for protection or other anti-rust treatment if necessary.
