Yes, HEDP (1-Hydroxy Ethylidene-1,1-Diphosphonic Acid) can be used with other monomers in various applications, particularly in water treatment, scale inhibition, and corrosion prevention. HEDP is a highly effective organic phosphonic acid that can be combined with other monomers to enhance its performance or achieve specific functional properties. Below are some common scenarios where HEDP is used with other monomers:
1. With Other Phosphonic Acid Monomers
Examples: ATMP (Amino Trimethylene Phosphonic Acid), DTPMP (Diethylenetriamine Penta(Methylene Phosphonic Acid)), EDTMPS (Ethylenediamine Tetra(Methylene Phosphonic Acid)).
Purpose: Combining HEDP with other phosphonic acids can enhance scale inhibition and corrosion prevention, especially in complex water systems.
Applications: Industrial cooling water systems, boiler water treatment, oilfield water treatment.
2. With Polymer Dispersants
Examples: HPMA (Hydrolyzed Polymaleic Anhydride), PAA (Polyacrylic Acid), PMA (Polymaleic Acid).
Purpose: HEDP can be used with polymer dispersants to improve the dispersion of suspended particles and enhance scale inhibition.
Applications: Reverse osmosis pretreatment, industrial circulating water systems.
3. With Corrosion Inhibitors
Examples: Zinc salts (e.g., Zinc Sulfate), Molybdate, Silicate.
Purpose: Combining HEDP with corrosion inhibitors can provide dual functionality—scale inhibition and corrosion protection.
Applications: Cooling water systems, central air conditioning systems.
4. With Biocides
Examples: Isothiazolinones, Quaternary Ammonium Compounds, Chlorine.
Purpose: HEDP can be used with biocides to prevent microbial growth and biofouling while inhibiting scale formation.
Applications: Industrial water systems, swimming pool water treatment.
5. With Green Scale Inhibitors
Examples: PESA (Polyepoxysuccinic Acid), PASP (Polyaspartic Acid).
Purpose: Combining HEDP with environmentally friendly scale inhibitors can improve eco-performance while maintaining effective scale inhibition.
Applications: Green water tre
