Usage:

It can inhibit the formation of various scale (such as calcium carbonate scale, calcium sulfate scale, barium sulfate scale and iron oxide scale, etc.), but it is mainly used to inhibit calcium sulfate and barium sulfate scale in water treatment. Among all kinds of organic phosphonic acids, its inhibition of calcium sulfate scale performance is the best, not only the scale inhibition rate is high, the effective time is long, so it is especially suitable for oilfield extrusion treatment. It can also be used in boiler water treatment. Like other nitrogen-containing phosphonic acids, this product is easily decomposed by oxidizing biocides such as liquid chlorine and becomes ineffective. Remedies are: the use of zinc ion stabilizer; Intermittent and impact dosing; Separate from chlorination point, etc.
