In textile printing and dyeing industry, HEDP (Hydroxyethylidene Diphosphonic Acid) is mainly used as chelating agent, color-fixing agent and dye dispersant with the following specific applications:

1. Preventing metal ions from interfering: HEDP is able to chelate calcium, magnesium, and other hard water ions in water, avoiding the reaction of these metal ions with dyes, thus ensuring the uniform adsorption of dyes and color fastness.
2. Color fixing treatment: After dyeing and printing, HEDP can be used as a color fixing agent, which reduces the interaction between dyestuffs and metal ions through the formation of stable chelates, enhances dyeing fastness and prevents fading.
3. Dye dispersion and stabilization: HEDP helps to improve the dispersion of dyes, preventing dyes from aggregation and precipitation, so as to ensure the uniformity of colors during the dyeing process.
4. Improvement of dyeing solution stability: By chelating metal ions, HEDP can reduce the formation of precipitation in the dyeing solution, improve the stability of the dyeing solution and reduce the dyeing defects.
5. Cleaning and descaling: Before dyeing, HEDP can be used to clean metal equipment, remove oxides and scale on the surface of the equipment, and prevent metal from polluting the dyeing solution.

The concentration of HEDP used in textile printing and dyeing is generally between 0.5% and 2%, and the specific dosage should be adjusted according to the actual demand.

HEDP (Hydroxyethylidene Diphosphonic Acid) is an organic phosphonic acid compound with the chemical formula C₂H₈O₇P₂ and molecular weight of 206.03. It is a highly efficient scale and corrosion inhibitor, which is able to form stable complexes with calcium, magnesium and other metal ions in water, thus effectively preventing the formation of scale.
HEDP has good chemical stability. HEDP has good chemical stability, in high temperature (up to 250 ℃) and high pH value conditions can still maintain stability, not easy to hydrolyze.
HEDP is widely used in scale and corrosion inhibition treatment in industrial circulating cooling water system, oil field water injection system, low pressure boiler, etc.
It is also used as peroxide stabilizer and color fixer in textile printing and dyeing industry, and as chelating agent in non-cyanide plating.The recommended dosage of HEDP is 1-10 mg/L (as scale inhibitor) or 10-50 mg/L (as corrosion inhibitor). Its solid form is crystalline powder, which is suitable for use in winter and cold regions.

ATMP (Amino Trimethylene Phosphonic Acid) is an organic phosphate compound with good chelating, scale inhibition and corrosion inhibition properties. It can effectively prevent scale formation of scale-forming salts (such as calcium carbonate) in water, and especially shows excellent corrosion inhibition effect when used in high concentration.ATMP is chemically stable and not easy to be hydrolyzed, so it is suitable for circulating cooling water system of thermal power plant and refinery, as well as oilfield re-injection water system, which can reduce the corrosion and scaling of metal equipment. In addition, it is also used in textile printing and dyeing industry as metal ion chelating agent and metal surface treatment agent.ATMP is usually used in combination with other organophosphonic acids, polycarboxylic acids or salts, and the recommended dosage is 1-20 mg/L (as scale inhibitor) or 20-60 mg/L (as corrosion inhibitor).

Shandong Kairui Chemical is a professional ATMP manufacturer.
