Miscible with water; Isothiazolinone can be added in any production step; easy to use.

Suitable for use in the medium of the pH value in the range of 2 to 9; free of divalent salt, cross-link no emulsion.Not suitable for use in the alkaline medium of pH> 9.0 due to its poor stability. Any combination of this chemical with highly nucleophilic chemicals, like S2- and R-NH2, will lead to declined quality or even complete failure of the product.

In water treatment applications, dilute it into a 1.5% aqueous solution first. Add the solution at a quantity of 80 to 100 ppm for one or two times each week depending on the multiplication of microorganisms like bacteria and algae.

When used as sludge stripper for grade II, the dosage of 150-300mg/L is preferred, when used as boicide, the dosage of 80-100mg/L is preferred, and charges every 3-7 days. No used together with oxidative fungicidal such as chlorine, and no used in cooling water system containing sulfur. When used together with quaternary amine, the effect will be better. When used as industrial fungicide, the dosage of 0.05-0.4% is preferred.

The application of isothiazolinone Kathon anticorrosion (CMIT/MIT) not only improves product quality, but also reduces costs, greatly improving product shelf life, water recovery and sustainable utilization of tap water sites.

HEDP (hydroxyethylidene diphosphonic acid) is a kind of organic phosphonic acid scale and corrosion inhibitor, which can form stable complexes with iron, copper, zinc and other metal ions, and can dissolve the oxides on the metal surface. In 250 ℃ can still play a good corrosion and scale inhibition, in high pH is still very stable, not easy to hydrolyze, general light and heat conditions are not easy to decompose. Acid and alkali resistance, chlorine oxidation resistance is better than other organic phosphonic acid (salt). It can form hexacyclic chelates with metal ions in water, especially calcium ions, thus it has better scale inhibition effect and obvious solubility limitation effect, when used in combination with other water treatment agents, it shows ideal synergistic effect.

HEDP solid belongs to high purity products, suitable for winter cold area; especially suitable for cleaning agent in electronics industry and additives for daily-use chemicals.

HEDP is widely used in electric power, chemical industry, metallurgy, fertilizer and other industrial circulating cooling water system and medium and low pressure boiler, oil field water injection and oil pipeline scale and corrosion inhibition; in the textile industry, it can be used as metal and non-metal cleaning agent, bleaching and dyeing industry peroxide stabilizers and color-fixing agents, cyanide-free electroplating industry complexing agent, pharmaceutical industry as a carrying agent for radioactive elements.

HEDP-Na4 (tetrasodium hydroxyethylidene diphosphonate) is mainly used in cleaning agents in the following aspects:

  1. Metal surface cleaning

HEDP-Na4 is able to form stable complexes with many metal ions, such as iron, copper, zinc, and so on, so as to effectively remove oxidization, rust, and mineral deposition on metal surfaces. This characteristic makes it excellent in metal surface cleaners, especially suitable for cleaning boilers, pipelines and other metal equipment.

  1. Industrial cleaners

    In industrial cleaners, HEDP-Na4 is commonly used to remove scale and mineral deposits. Its chelating ability prevents metal ions such as calcium and magnesium from combining with anions in water to form scale, and also dissolves already formed scale. In boiler cleaning agent, the concentration of HEDP-Na4 is usually 1000-2000mg/L.

    1. Cleaning application in light textile industry

    In light textile industry, HEDP-Na4 can be used as a metal and non-metal cleaning agent for removing impurities and metal ions on the surface of fibers to improve the cleanliness and softness of fabrics.

  2. Application in daily chemicals

    HEDP-Na4 can also be used as a component of household detergents to improve the cleaning effect and prevent the redeposition of limescale and stains. In addition, in cosmetics and personal care products, HEDP-Na4 acts as a chelating agent to prevent metal ions from interfering with product stability.

  3. Other cleaning-related applications

    Printing and dyeing industry: as a peroxide stabilizer and color-fixing agent, preventing color changes caused by the combination of dyes and metal ions, and improving dyeing uniformity and color stability.

    Paper industry: as bleaching auxiliary and retention aid, to prevent metal ions from interfering with bleaching agent and improve the quality and strength of paper.

Summarize

HEDP-Na4 is widely used in cleaning agents, mainly due to its excellent chelating ability and corrosion inhibition performance. It can effectively remove oxides and mineral deposits on metal surfaces while preventing scale formation and redeposition, and is widely used in many fields such as industry, light textiles, and daily-use chemicals.
