Ungakuvimbela kanjani ukugqwala kwamayunithi okushintshanisa ukushisa kwepuleti?

Ngenxa yezimo zemvelo ezilinganiselwe zasembonini, iyunithi yesishintshi sokushisa samapuleti nakanjani izoba nezinkinga zokugqwala ngemva kwesikhathi esithile sokusetshenziswa. Ukuze kuthuthukiswe izinga lokusetshenziswa kwezisetshenziswa, ukulwa{1}}nokugqwala nakho kungomunye wemisebenzi ebalulekile.

Iisishintshi sokushisa esihlakaniphileiwuhlelo lokushintshanisa ukushisa olwakhiwe izishintshi zokushisa zamapuleti amaningi ezidlulisa ukushisa ukusuka kolunye uketshezi kuye kolunye. Iqukethe uchungechunge lwamapuleti okushisa amapuleti, ngalinye lakhiwe uchungechunge lwamapuleti e-aluminium namashubhu athandeka. Kukhona izikhala ezithile phakathi kwalawa mapuleti e-aluminium namashubhu asonge, okuvumela uketshezi olubili oluhlukene ukuthi luthintane esikhaleni, ngaleyo ndlela kuzuzwe ukudluliswa kokushisa. Inzuzo yeyunithi yesishintshi sokushisa samapuleti ukuthi inganikeza-ukushintshashintsha kokushisa okusebenzayo, nezinhlanganisela ezihlukahlukene zesishintshi sokushisa zingaklanywa ngokuvumelana nezidingo zamakhasimende ukuze kuhlangatshezwane nezidingo ezihlukene.

I-corrosion inhibitor esetshenziswa ohlelweni lwamanzi okupholisa ikakhulukazi yakhiwe i-chromate, ngoba i-ion ye-chromate ngokwayo iyisivimbeli senqubo ye-anodic. Uma kune-cathodic inhibitor efanelekile, ziyasabela futhi zihlangane ndawonye ukuze sifeze injongo yethu yokulwa{1}}nokugqwala.

I-Chromate-i-zinc{1}}i-polyphosphate isetshenziselwa ukuvimbela ukugqwala. I-Polyphosphate ngokwayo inamandla okuvimbela ukugqwala nokuhlanza indawo yensimbi. Ngenxa yokuthi i-polyphosphate ingashintshwa ibe i-orthophosphate emanzini, i-orthophosphate ingenza ama-colloidal cations amakhulu nama-calcium ions emanzini, avimbela i-cathode futhi ngaleyo ndlela ifeze injongo yokuvimbela ukugqwala.

I-Chromate-i-zinc-i-phosphate isetshenziselwa ukuvikela ukugqwala. Umgomo wokusebenzisa i-sodium phosphate ne-polyphosphate iyafana. Inani le-pH yendawo yokufaka i-phosphate lingaba phezulu kunalelo le-polyphosphate. I-Phosphate ivimbela ngokuyinhloko ukwakheka kwesikali futhi ingabangela usawoti we-calcium ukuthi uhle ngisho nasendaweni enenani le-pH elifika ku-9.

I-Chromate-izinc{1}}i-hydrolyzed polyacrylamide isetshenziselwa ukuvikela ukugqwala. I-Hydrolyzed polyacrylamide iyi-cationic copolymer enomthelela ohlukile emanzini futhi ingavimbela isikali ukuthi siguquke sibe ukungcola.

Ukuvikelwa kwe-Cathodic kanye nokuvikelwa kwe-anodic kusetshenziselwa ukuvimbela ukugqwala. Ukuvikelwa kwe-Cathodic kuhilela ukungeza umthombo wamandla we-DC endaweni yensimbi yesishintshi sokushisa sepuleti, uyiguqule ibe yi-cathode, ngaleyo ndlela inikeze isivikelo. Nokho, le ndlela idla amandla amaningi futhi iyabiza. Ukuvikelwa kwe-anodic kuhilela ukungeza i-anode enamandla kusishintshi sokushisa, okudala ifilimu ye-passivation endaweni yensimbi, efinyelela ukuvikeleka kokugqwala.
