Cooling circulating water treatment agents are chemicals used to deal with the industrial cooling water system. It aims to prevent problems such as corrosion, stains, microbial growth and precipitation in the cooling water system to maintain the efficient operation of the system and extend the life of the equipment. The following is a common cooling circulating water treatment agent and its role:
Corrosion inhibitors: Corrosion inhibitors can form a protective film, covering the metal surface to prevent metal corrosion. Common corrosive inhibitors include phosphate, sulfate, and organic acid.
Salcidal inhibitors: The stains inhibitors are combined with the hardness ions in the water to prevent the formation and accumulation of hard scale, thereby reducing the heat conduction resistance of the equipment and avoiding blocking the cooling water pipeline. Commonly used inhibitors include phosphate and corrosion agent.
Microbial control agent: Microbial control agents are used to prevent microbial growth in the cooling water system, including bacteria, algae and fungi. Common microbial control agents include bactericides, inhibitors and biofluidists.
Washing agent: The cleaning agent is used to remove the stain, pollutants, and sediments in the cooling water system to maintain the smoothness and efficiency of the system. The cleaning agent can dissolve hard scale, iron rust and other impurities, and rinse or discharge the cooling water system.
PH regulator: PH regulator is used to maintain the appropriate pH range in the cooling water system to reduce corrosion and stain accumulation. In an alkaline environment, the PH regulator can help suppress acid corrosion; in an acidic environment, the PH regulator can help suppress alkaline corrosion.
The selection and use of cooling circulating water treatment agents need to be determined according to the specific cooling water system conditions, water quality characteristics and process requirements. Before use, follow the instructions and suggestions provided by the manufacturer, and invest and monitor in accordance with the correct proportion and control measures. In addition, reasonable management and regular system cleaning are also the key to maintaining the stable operation of the cooling water system.
