Embodiment 1
[0027] Preparation of Ascorbic Acid Phosphorus-Free Corrosion and Scale Inhibitor
[0028] The material is taken according to the following composition mass percentages, hydrolyzed polymaleic acid 15%-20%, acrylic acid-2-acrylamide-2-methylpropanesulfonic acid 10%-15%, ascorbic acid 0.6%-1%, aminosulfonic acid 0.5% to 1%, zinc nitrate or zinc sulfate 10% to 15%, D-sodium gluconate 10% to 15%, the rest is distilled water, and then hydrolyzed polymaleic acid, acrylic acid-2-acrylamide-2-methyl Propanesulfonic acid, ascorbic acid, sulfamic acid, zinc nitrate or zinc sulfate, D-sodium gluconate or D-potassium gluconate, and distilled water are added to the container in the above order and stirred for 0.5h to 1h. The product is obtained when the mixture is clear and free of insoluble impurities.
Embodiment 2
[0030] Prepare 100g of ascorbic acid phosphorus-free corrosion and scale inhibitors, preparation process: get 50% hydrolyzed polymaleic acid 16.8g, 30% acrylic acid-2-acrylamide-2-methylpropanesulfonic acid 11g, ZnSO 4 .7H 2 Add 12g of O, 12.8g of sodium D-gluconate, 0.7g of ascorbic acid, 0.8g of sulfamic acid, and the rest in distilled water into a clean and dry beaker, and stir evenly to obtain the product.
