Kuita

HEDPio organophosphoric acid ngura inhibitor. Inogona chelate neFe, Cu, uye Zn ions kuti vagadzikane yakatsiga chelating makomponi.Iyo inogona kuputsa iyo oxidized zvinhu pane aya esimbi nzvimbo.HEDP inoratidza yakanakisa chiyero uye ngura inhibition mhedzisiro pasi pekupisa 250 ℃. HEDPine yakanaka makemikari kugadzikana pasi yepamusoro pH kukosha, yakaoma kuve hydrolyzed, uye yakaoma kuora pasi peyakajairika mwenje uye kupisa mamiriro Iyo acid / alkali uye klorini oxidation kushivirira zviri nani pane izvo zveimwe organophosphoric acids (munyu).HEDPinogona kuita nesimbi ions mumvura sisitimu kugadzira hexa-element chelating yakaoma, ine calcium ion kunyanya. Naizvozvo,HEDPine yakanaka antiscale uye inooneka chikumbaridzo mhedzisiro. Ikavakwa pamwe chete nemamwe makemikari ekurapa mvura, inoratidza zvakanaka synergistic mhedzisiro. Iyo yakasimba mamiriroHEDPsekristaro poda, yakakodzera kushandiswa munguva yechando uye matunhu anotonhora. Nekuda kwekuchena kwaro kwepamusoro, inogona kushandiswa seanochenesa mumagetsi emagetsi uye sezvimwe zvinowedzera mumakemikari ezuva nezuva.

Kushanda

HEDP inoshandiswa seyero uye ngura inhibition mukutenderera inotonhorera sisitimu yemvura, oiri munda uye yakaderera-kumanikidza boiler muminda senge magetsi magetsi, kemikari indasitiri, simbi, fetiraiza, nezvimwe. Mune mwenje yakarukwa indasitiri, HEDPinoshandiswa se detergent yesimbi uye isiri metall. Muindasitiri yekudhaya,HEDPinoshandiswa se peroxide stabilizer uye dhayi-inogadzirisa mumiriri; Mune isiri-cyanide electroplating,HEDPinoshandiswa seanobiridzira mumiriri. Muyero we1-10mg / L unosarudzwa senge muyero inhibitor, 10-50mg / L seyorroshibitor inhibitor, uye 1000-2000mg / L seyadhi. Kazhinji,HEDP inoshandiswa pamwechete ne polycarboxylic acid.
