    FAQs about Water Treatment Chemicals

    Product Tags

    1. Industrial Water Treatment

    Used in industrial cooling water, circulating water, oilfield reinjection water, and thermal power plant systems to kill bacteria, control algae, and remove biological slime, thereby preventing corrosion and blockages in pipes and equipment.

    2. Household Chemicals and Personal Care Products

    Added as a preservative to shampoos, conditioners, body washes, face creams, lotions, and other cosmetics and cleansers to prevent product spoilage.

    3. Coatings, Paints, and Polymer Materials

    Added to water-based coatings, paints, emulsion paints, and polymer emulsions (such as acrylic resins) to prevent in-can deterioration and mold growth on coatings.

    4. Paper Industry

    Used as a preservative in process water, coatings, and starch slurries during papermaking to prevent microbial degradation of raw materials and paper damage.

    5. Metalworking and Industrial Cleaning

    Added to cutting fluids, grinding fluids, quenching fluids, and industrial cleaning agents to extend the service life of working fluids and prevent odor and spoilage.

    6. Textiles and Leather

    It is used as an antifungal agent in textile sizing agents and leather treatment agents to prevent mold growth in humid environments.

    7. Petroleum and Fuels

    It can used as a biocide in refineries for fuels and petroleum products.

    8. Other Industrial Applications

    Also used for preservation and mold prevention in insecticides, inks, dyes, photographic film, rubber, and other products.

     

    It can also be used in:

    ● Photographic chemical sensitizers

    ● Indoor air fresheners

    ● Raw materials for audio tapes

    ● Plant growth regulators

    Advantages

    1. Highly effective and broad-spectrum, capable of killing and inhibiting various microorganisms, molds, and algae;

    2. Wide applicability; bactericidal efficacy remains unaffected across a pH range of 3 to 9.5;

    3. Excellent compatibility; widely compatible with various anionic, cationic, and nonionic additives, and can be used in combination with other biocides;

    4. Low application concentration, long-lasting efficacy, and no foaming;

    5. Effectively prevents slime formation;

    6. Convenient and safe to use; can be added directly;

    7. Environmentally friendly; biodegrades into non-toxic substances, posing no environmental hazards even with long-term use.

    Mode of Action

    CMIT/MIT exerts its biocidal effect by breaking the bonds in bacterial and algal proteins. Upon contact with microorganisms, it rapidly and irreversibly inhibits their growth, leading to cell death. Consequently, it exhibits strong inhibitory and killing effects against common bacteria, fungi, and algae.

    Dosage

    ●  When used as a biofilm stripper, the dosage is 150–300 mg/L;

    ●  When used as a biocide, it should be added once every 3–7 days at a dosage of 80–100 mg/L.

    ●  It can be used concurrently with oxidizing biocides such as chlorine, but should not be used in cooling water systems containing sulfides.

    ●  CMIT/MIT achieves better results when used in combination with quaternary ammonium salts.

    ●  When used as an industrial biocide and antifungal agent, the typical concentration is 0.05–0.4%.

    Packaging
