Embodiment 1
[0023] A corrosion and scale inhibitor for circulating cooling water, comprising the following components by mass percentage: organophosphorus (2-hydroxyphosphonoacetic acid) 4%, dispersant (2-phosphonobutane-1 , 2,4-tricarboxylic acid) 2%, copolymer (acrylic acid-2-acrylamide-2-methylpropanesulfonic acid-phosphinic acid telomer) 30%, zinc salt (zinc chloride) 10%, Deionized water 54%.
[0024] experimental method:
[0025] Corrosion inhibition performance was measured with reference to "GB / T 18175-2000 Determination of Corrosion Inhibition Performance of Water Treatment Agents by Rotating Coupon Method". The materials for the coupons used in the experiment were Q235 carbon steel and 316L stainless steel. Hang three pieces of each material, and the results are averaged.
[0026] Refer to "GB / T 16632-2008 Calcium Carbonate Deposition Method for Determination of Scale Inhibition Performance of Water Treatment Agents" to measure the scale inhibition performance.
