Applications
1. Circulating Cooling Water Systems works by threshold inhibition and lattice distortion rather than stoichiometric chelation, so a small feed rate holds calcium carbonate off heat exchanger tubes and keeps thermal power and refinery cooling loops at design heat transfer.
2. Boiler And High Hardness Water handles the harsh end of the water spectrum, including high hardness, high salinity and otherwise poor quality make up water, and it resists hydrolysis so performance does not drift across long operating cycles.
3. Oilfield Water Injection And Gathering Lines keeps scale from closing off injection lines, gathering pipes and wellbore equipment, and at higher feed rates it also suppresses corrosion on the steel surfaces those streams contact.
4. Textile And Dyeing Operations chelates the hardness and trace metals that interfere with dyebaths and finishing liquors, which helps dyers hold shade consistency and avoid the spotting that metal ions leave on fabric.
5. Detergents, Cleaning And Metal Surface Treatment a chelating and deflocculating agent that carries into industrial cleaners and metal pretreatment baths, holding hardness ions and soils in suspension instead of letting them redeposit on cleaned surfaces.
6. All Organic Alkaline Treatment Blends combines with other organophosphonates and polycarboxylic acid polymers to build all organic alkaline water treatment programs, giving formulators a stable phosphonate base for such blends.
