Scale and Corrosion Inhibitor for Power Plant DM-8

Scale and Corrosion Inhibitor for Power Plant DM-8302 Properties This product is the new multi-functional special corrosion inhibitor for power plant, which is composed of organic phosphonic acid, phosphonate-containing copolymer and copper corrosion inhibitors. With reaction with divalent metal ions in water, the product can make the insoluble difficult to settle and maintain crystal in a very small particle range to achieve solubilization effect. It has excellent scale inhibition and dispersion on calcium carbonate and form a layer thin and dense protective film on the surface of copper to greatly reduce the corrosion rate. The product can be used in high hardness, high alkalinity water power plant and circulating cooling water chemical treatment. At the higher concentration multiple and high pH (8.5 9.2) value, it has obvious effect on preventing condenser copper pipe fouling and brass de-zinc corrosion and can achieve the purposes of high concentration times running in none or less adding acid for different water quality and devices. Quality Index item A Class B Class C Class Azole (calculation by C6H4NHN contrast N) content % ≥ —— 1.0 3.0 Phosphonate (calculation by PO43-) content %≥ 6.8 Phosphorous Acid (calculation by PO33-)content % ≤ 2.25 Orthophosphat (calculation by PO43-) conten t%≤ 0.75 Solid content % ≥ 32.0 PH (1% aqueous solution) 3.0±1.5 Density (20°C) g/cm3 ≥ 1.15 Use The normal amount is 50 100mg / l, combined with sponge balls washing technology. According to the water quality, at higher concentration running system, adding appropriate acid, alkali to adjust pH value to 8.5 9.2. Packing and storage Net weight: 25kg Packed in plastic drum. Stored in a room ventilated dry place, storage period for one year.
