I-1-Hydroxy Ethylidene-1,1-Diphosphonic Acid (HEDP) — Umnakekeli Osebenzayo Wokwelashwa Kwamanzi Ezimboni

I-1-Hydroxy Ethylidene-1,1-Diphosphonic Acid (HEDP), isikali esiyinhloko kanye nesivimbeli sokugqwala somndeni we-organic phosphonic acid, isibe yikhemikhali ekhethwayo yokwelashwa kwamanzi ezimbonini kanye nokusetshenziswa kwezindawo eziningi ngenxa yesakhiwo sayo samakhemikhali esizinzile kanye nokusebenza kwayo okuvelele. Ivikela ukusebenza kwesikhathi eside kwemishini kanye nentuthuko ephumelelayo yezimboni.

Izinzuzo eziyinhloko ze-HEDP zisekumelaneni nokushisa okuphezulu, ukumelana ne-asidi ne-alkali, kanye nomthamo oqinile we-chelating. Isakhiwo sayo esiyingqayizivele se-CP bond simelana ne-hydrolysis futhi sigcina ukusebenza okuzinzile ngaphansi kokushisa okuphezulu okufika ku-250℃ kanye nobubanzi be-pH obubanzi obungu-2-12, ngokumelana nokushiswa kwe-chlorine okuphezulu kakhulu uma kuqhathaniswa nemikhiqizo efanayo ye-organic phosphonic acid. Amaqembu e-bisphosphonic acid kuma-molecule awo angakha ama-chelate endandatho aqinile anamalungu ayisithupha ane-ion yensimbi njenge-calcium, i-magnesium, insimbi nethusi, okuvimbela ngempumelelo ukwakheka kwesikali okuhlanganisa i-calcium carbonate ne-calcium sulfate. Inikeza imiphumela emihle kakhulu yokuvimbela isikali ngisho nasezilinganisweni eziphansi futhi inomphumela ophansi, ngemiphumela emangalisayo yokusebenzisana lapho isetshenziswa ekwakhiweni kwe-compound.

Inezici eziningi nezihlukahlukene zokusetshenziswa. Ezimbonini, isetshenziswa kabanzi emanzini apholile ajikelezayo, ama-boiler aphakathi nendawo naphansi, amapayipi okufaka amanzi e-oyela kanye nokudlulisa uwoyela ngamandla, amakhemikhali, i-metallurgical, umanyolo wamakhemikhali kanye neminye imboni, okuvimbela ngempumelelo ukufakwa kwesikali nokugqwala, kuthuthukisa ukusebenza kahle kokushintshana kokushisa futhi kwandise impilo yesevisi yemishini. Embonini yezindwangu nokukhanya, isebenza njenge-ejenti yokuhlanza insimbi/engeyona insimbi, i-peroxide stabilizer kanye ne-ejenti yokulungisa umbala yokumhlopheza nokudaya. Ngaphezu kwalokho, ingasetshenziswa njenge-ejenti yokuhlanganisa i-electroplating engena-cyanide, i-ejenti yokuhlanza ehlanzekile kakhulu embonini ye-elekthronikhi kanye nesengezo semikhiqizo yamakhemikhali yansuku zonke. Njengoba inobuthi obuphansi kanye nobungane bemvelo, ihlangabezana nezidingo zezimo ezahlukahlukene.

Ukukhetha i-HEDP kusho ukukhetha ikhambi elisebenza kahle, elizinzile nelingabizi kakhulu. Lixazulula izinkinga zokukala nokugqwala ngokusebenza kahle kakhulu, linciphisa izindleko zokusebenza nokugcinwa, futhi lisiza izinhlelo zezimboni ukonga amandla futhi linciphise ukusetshenziswa, okwenza kube yi-ejenti ewusizo yamakhemikhali esebenza kahle kakhulu ekukhiqizweni kwezimboni zanamuhla.
