Daim ntawv thov:
1.HEDP yog siv los ua scale thiab corrosion inhibition nyob rau hauv circulating dej txias system, roj teb thiab low-pressure boilers nyob rau hauv teb xws li hluav taws xob fais fab, tshuaj lom neeg kev lag luam, metallurgy, chiv, thiab lwm yam.
2.Nyob rau hauv lub teeb woven kev lag luam, HEDP yog siv los ua detergent rau hlau thiab nonmetal. Hauv kev lag luam dyeing, HEDP yog siv los ua peroxide stabilizer thiab dye-fixing tus neeg saib xyuas;
3.In non-cyanide electroplating, HEDP yog siv los ua tus neeg sawv cev chelating. Qhov ntau npaum li cas ntawm 1-10mg / L yog nyiam raws li nplai inhibitor, 10-50mg / L raws li corrosion inhibitor, thiab 1000-2000mg / L ua tshuaj ntxuav.
4. Feem ntau, HEDP yog siv ua ke nrog polycarboxylic acid.
