Ukwakhiwa kwamakhemikhali we-rust converter "Tsinkar"
Okuqukethwe
I-Zinkar yenziwe ngani?
Ukwakhiwa kwamakhemikhali e-Tsinkar kuphephile kubantu, kodwa ngesikhathi esifanayo kuhlanganisa izinto ezisebenzayo ezibhekana ngokuphumelelayo nezikhungo zokubhujiswa kwensimbi. Isekelwe ku-phosphoric acid ehlanjululwe kusetshenziswa amasu akhethekile futhi ihlanjululwe ngamanzi, lapho i-zinc ne-manganese compounds yengezwa khona.
Isici esibalulekile se-rust converter i-Zinkar ukuthi ukwakheka kwesixazululo kuhlanganisa i-manganese ne-zinc esimweni esisebenzayo, esakha ifilimu yokuzivikela yamandla akhethekile endaweni yensimbi. Ososayensi baye bafakazela ukuthi izakhi zamakhemikhali ezisebenzayo zomuthi, ezisebenza ngababili, ezenza kube nokwenzeka ukufeza ukusebenza kahle kwe-Tsinkar - cishe izikhathi ezingu-2-2,7 ngaphezu kwezixazululo ze-monophosphate, ezinkulu emakethe futhi zikhona. ishibhile, kodwa ukonga akufanelekile .
Zisebenza kanjani izinto ezakha isiguquli sokugqwala i-Zinkar?
Umsebenzi oyinhloko we-zinc uwumphumela oqondile ezikhungweni zokugqwala kwe-electrochemical, ukwakhiwa kokuvikelwa kwensimbi evikelayo. Incazelo yalo itholakala eqinisweni lokuthi ngaphansi kwethonya lobuningi bomoya umvikeli uyahlukana, eqinisekisa ukuphepha kwezakhi zensimbi ngaphansi kwayo.
Ngosizo lwe-manganese, indawo ephathwayo i-alloyed, okungukuthi, izimfanelo zesendlalelo sokuzivikela ziyathuthukiswa, okuphinde kuhlukanise i-Zincar ne-monophosphate compounds.
I-Orthophosphoric acid yenza kube nokwenzeka ukuthi kokubili i-zinc kanye ne-manganese zikwazi ukuziveza ngendlela engcono kakhulu. Umshini wesenzo sawo ukwakhiwa kwesendlalelo sokuzivikela ngendlela yefilimu ye-phosphate, ethuthukisa kakhulu ukunamathela, okungukuthi, ukunamathela kwendawo yensimbi kanye nezinto zokudweba ezisetshenziswa kuyo. Uma upende kanye nezingqimba ze-phosphate zonakalisiwe, ukukhula kwezikhungo zokubola kuyeka ngaphakathi kwemingcele yendawo lapho ubuqotho bongqimba buphuliwe. Ngesikhathi esifanayo, umphumela we-phosphoric acid esikalini kanye nama-non-hydrated oxides uyancishiswa.
Ngaphezu kwalokho, isixazululo seZinkar siqukethe i-tannin, kanye ne-adsorption kanye ne-passivating inhibitors. Eyokuqala iyadingeka ukuze kuguqulwe i-iron oxide ibe yizinhlanganisela ezivumela izinhlayiya zokugqwala ukuba zinamathele ezingeni lamangqamuzana komunye nomunye kanye nesisindo esingaguquki sensimbi. Lezi zokugcina zenzelwe ukunciphisa izinqubo zokugqwala ngangokunokwenzeka, futhi ukudlula kwenzeka ngosizo lwezinto ezinezici ze-oxidizing. Isendlalelo esivikelayo, okuhlanganisa izakhi ezidlulayo, sinciphisa izinga lokugqwala kwezinsimbi. Umgomo wokusebenza kwe-adsorption inhibitors wukwakhiwa kwefilimu eyengeziwe ongqimbeni lwe-oxide, okuthuthukisa ukuvikelwa kokugqwala.
Umphumela wokusebenzisana kwezakhi zamakhemikhali
Ukwakhiwa kwamakhemikhali e-Tsincar kusivumela ukuthi sikhulume ngalokhu okulwa nokugqwala njengenye ye-anti-corrosion agents engcono kakhulu ngokusebenza kahle. Ngokushesha ngemva kokusebenzisa isixazululo kungqimba lwensimbi oluthintekile, izakhi ezakha umkhiqizo ziqala ukubhubhisa ukugqwala, kuyilapho amafomu e-oxide ensimbi eguqulwa abe yi-phosphate. Phakathi nale nqubo, i-manganese isabela ne-zinc. Bafaka isandla ekwakhiweni kongqimba oluthembekile lokuvikela lwezakhi ezisebenzayo.
