Yintoni i-ATMP?

I-ATMP (i-amino trimethylene phosphonic acid, kunye ne-NTMP - i-nitrilotrimethylene phosphonic acid) yi-organophosphonate compound enamaqela amathathu e-phosphonic acid aqhotyoshelwe kwiibhulorho ze-methylene ukuya kwi-nitrogen ephakathi. I-ATMP iphakathi kwezona zithinteli zesikali ezisetyenzisiweyo nezisetyenziswa kakhulu kwi-chemistry yonyango lwamanzi - ingabizi kakhulu, ifumaneka ngokubanzi, kwaye ibonelela ngokuthintela isikali esimiselweyo kwiintlobo zesikali eziqhelekileyo (i-calcium carbonate, i-calcium sulfate) ezifunyanwa kwiinkqubo zamanzi okupholisa ezimbonini kunye namanzi ebhoyila. Njengezinye ii-organophosphonates, i-ATMP isebenza ngendlela yokuthintela isikali, inamathela kwiindawo ezisebenzayo zokukhula kwekristale ye-incipient scale kwaye ithintela uphuhliso oluqhubekayo lwekristale kwimilinganiselo engaphantsi kakhulu kwe-stoichiometric equivalent.

Ukusetyenziswa kwamanzi okupholisa kunye namanzi ebhoyila

Kwindlela yokupholisa amanzi, i-ATMP isetyenziswa kwi-2–5 mg/L njengesithinteli sesikali, idla ngokudityaniswa nezinyibilikisi zepolymeric (i-polyacrylic acid, i-HPMA) kunye nezithinteli zokugqwala (i-zinc sulfate, i-benzotriazole, i-molybdate) kwiinkqubo zonyango ezixutyiweyo. Ibonelela ngolawulo lwesikali se-calcium carbonate kunye ne-calcium sulfate kwi-heat exchangers kunye ne-cooling tower fill. I-ATMP ikwasebenza njenge-iron sequestrant - ilungelelanisa i-iron enyibilikisiweyo kwaye ithintela ukufakwa kwe-iron oxide (umhlwa). Kwiinkqubo ze-boiler ezinoxinzelelo oluphantsi, i-ATMP isetyenziselwa ukwahlula ii-ion zobunzima (i-calcium, i-magnesium) kwaye ithintele isikali kwiindawo zokudlulisa ubushushu. Ihlala izinzile ngakumbi kwi-hydrolytic kunezithinteli ze-polyphosphate kwiindawo ezishushu zamanzi.

Izicelo zamanzi zeOyile kunye nezinye iindawo zeOyile

Kwiinkqubo zamanzi ezifakwa kwi-oyile kunye nolawulo lwesikali semibhobho yomphezulu, i-ATMP isetyenziswa ukuthintela ukwakheka kwesikali se-carbonate. Ikwasetyenziswa ekwenzeni iimveliso ezixutyiweyo ze-antiscalant zonyango lwangaphambi kwe-membrane ye-reverse osmosis (RO) ukuthintela isikali se-carbonate kunye ne-sulfate kumphezulu we-membrane. I-Terracore Chemicals inikezela nge-ATMP njengesisombululo samanzi se-50% kwiinkqubo zonyango lwamanzi kulo lonke elaseMzantsi Afrika.
