I-Etidronic acid / HEDP / CAS: 2809-21-4
Incazelo emfushane:
Igama lomkhiqizo: Etidronic acid
Case: 2809-21-4-4
MF: C2H8O7P2
MW: 206.03
Isakhiwo:
Ubuningi: 1.45 (60% AQ.)
I-Flash Point: 198 ~ 199 ℃
Umkhiqizo omsulwa uyi-crystal emhlophe. Umkhiqizo wezimboni awunalo umbala wokukhanya okukhanyayo okusobala. Kuyancibilika kalula emanzini futhi kuncibilike ku-methanol nase-ethanol. IHydroxYethyLene Diphosphonic acid iyinto eluhlaza enamakhemikhali futhi ivame ukusetshenziswa ekwelashweni kwamanzi kwezimboni, imikhiqizo yokuhlanza indlu yasendlini nemikhiqizo yokuzinakekela ekhaya kanye nemikhiqizo yokunakekelwa komuntu.

Umsebenzi
Lo mkhiqizo uwukuqukethwe okuyinhloko okungavuthiwe kwe-electide-free electroplating. Lapho kwakhiwa ikhambi le-electroplating ye-cherper-free ye-cyanide, linamandla amakhulu okubopha lapho ngokuqondile ukhetha ungqimba lwethusi ngensimbi ye-sodium. I-coating ibushelelezi futhi ine-luster enhle. Ngokuvamile, umthamo womkhiqizo onokuqukethwe okungu-60% ngu-100 - 120 ml / l. Umthamo we-sulfate yethusi yi-15 - 20 g / l. Ngaphezu kwalokho, ngaphambi kwe-electroplating, gezela izingxenye ze-plating ku-1% - 2% isixazululo salo mkhiqizo ukwenza izingxenye ze-plating ziphenduke isimo esisebenzayo. I-electroplating ngemuva kwalesi sinyathelo ingaqhubeka nokwenza ngcono umphumela. IHydroxYethyLidene Diphosphonic acid (HEDP) uhlobo olusha lwe-chlorine-free electrorine-free electrorine Isetshenziswa njenge-ejenti eyinhloko yokuzinza kwekhwalithi yamanzi kuhlelo lokupholisa lwamanzi lokupholisa, kudlala indima yokuvimbela ukuthuthuka nokuvimbela. Lo mkhiqizo ungenye yama-organic polyphosphonic acid Meter Treatter Treatter Agents. Kukhona nezinye izinhlobo zalolu hlobo lwemikhiqizo ekhiqizwa eChina, njenge-Amino Trimethylene Phosphonic Acid ([CH2PO (OH2PO (OH2POMINE TETRA (ETCMPYINIMI ADRA (ETCMPYINIMI Acids zakhiwa ngasekupheleni kwawo-1960 futhi zamukelwa ngabo-1970s. Ukuvela kwalolu hlobo lwama-agents ukwelashwa kwamanzi kunezobuchwepheshe bokulashwa kwamanzi athuthukile ngesinyathelo esikhulu. Uma kuqhathaniswa nama-polyphosphates ama-inorganic, ama-polyphosphonic acid anokuqina okuhle kwamakhemikhali, akulula ukuqina kwe-hydrolyze, angamelana namazinga okushisa aphezulu, adinga umthamo omncane we-ejenti, futhi abuye abe nezakhiwo zokuvimbela zombili zokugqwala kanye nokuvimbela. Banguhlobo lwe-cathodic corrosion inhibitors futhi futhi uhlobo lokungezinhlangothi ezingezona ezi-inhibitors. Lapho isetshenziswa ngokuhambisana namanye ama-ejenti wezokwelapha amanzi, akhombisa umphumela omuhle kakhulu we-synergistic. Banekhono elihle kakhulu le-Phelating ngama-ion amaningi wensimbi afana ne-calcium, i-magnesium, yethusi, ne-zinc. Baphinde babe nomthelela omuhle okhonzeni ngosawoti walezi zinsimbi, njenge-CASO4, CACO3, MGSO3, njll. Ngakho-ke, asetshenziswa kabanzi kubuchwepheshe bokwelashwa kwamanzi. I-Phosphorylating reagents isetshenziselwa i-serine ne-pyranose evikelwe.
