 In actual water treatment systems, biocides are often used together with scale inhibitors, corrosion inhibitors, dispersants, and pH adjusters. Therefore, CMIT/MIT compatible with other water treatment chemicals is an important performance index. CMIT/MIT has excellent compatibility with most anionic, cationic, and non-ionic water treatment agents, including organophosphonates, polycarboxylates, zinc salts, and molybdate-based corrosion inhibitors. It does not produce precipitation or lose efficacy when compounded. Shandong Kairui Chemistry Co., Ltd can provide compound formulations and professional guidance to achieve synergistic effects.

Paper mills face serious slime and microbial contamination due to rich organic matter in white water and process water. Slime deposition causes paper defects, equipment blockage, and production losses. CMIT/MIT for paper mill water treatment and slime control is highly effective and widely applied. CMIT/MIT inhibits slime-forming bacteria, molds, and yeast, reduces deposition on wires, felts, and pipelines, and improves paper quality and production efficiency. It has low foaming and good compatibility with papermaking additives. Shandong Kairui Chemistry Co., Ltd provides high-stability CMIT/MIT products suitable for paper mill water systems.

 Boilers are core power equipment in industrial production, central heating, and manufacturing facilities, and stable water quality control is the top priority to ensure their safe and efficient operation. Traditional boiler water treatment agents often carry phosphorus or toxic components, which not only pose risks to boiler pipes and heat exchange parts but also fail to meet strict global environmental discharge standards. Polyepoxysuccinic Acid (PESA) stands out as a tailored solution for boiler water systems, solving long-standing scaling and corrosion troubles while fully complying with green production norms. Boiler water operates under high temperature and high pressure for a long time, making it extremely prone to forming hard, compact scale on the inner walls of boiler barrels, smoke pipes, and circulation pipelines. This scale drastically reduces heat transfer efficiency, increases fuel consumption by up to 20%-30%, and even causes local overheating, pipe bursting, and fo...
