circulating water treatment medicament

1. the composited scaleinhibition corrosion inhibitorZH521 KS-529KS corresponding the standard of sinopec function 2.The production mainly apply to HAG treatmetn of open circulating cooling water in oil refining, chemical industry, chemical fertilizer,steelmaking and so on, which have a good role for corrosion inhibition for carbon steel, copper, aluminium and stainless steel. 3, the quality index(according with the standard of sinopec SH2604.03---2003) (a) appearance: colourless or faint yellow transparent liquid, no sediment. (b) density(20°C),g/cm³:≥1.12 (c) pH(1%aqueous solution):≤4.50 (d) phosphate(asPO43- calculate)content,%:6.0—10.0 (e) phosphorous acid(asPO33- calculate)content,%:≤0.40 (f) imidazole(as C6H4NHN calculating)content,%:≥0.80(g)solisd content%:≥25.0 4, usage applying to Open circulating cooling water system,controling the content of organic poosphint in the water when working 3 8mg/L,do not influence the effect of anti-scaling and corrsion inhibition when ventilating with chlorine. As the different water quality,effective distribute in the formula do the relevant adjust as the different model ZH 521 KS—529KS. 5,packing and keeping packing with 25kg plastic drum. keeping in the shade place, the storage period of a year.
