1 Njengezithibi Zokucinywa Kwe-Acid
Ngesikhathi sokupheka, i-hydrochloric acid, i-sulfuric acid, noma i-nitric acid ngokungenakugwenywa isabela ne-substrate yensimbi ngenkathi isabela ngokugqwala kanye nobukhulu, ikhiqiza ukushisa futhi ikhiqize inani elikhulu le-acid inkungu. Ukwengeza ama-surfactants kusisombululo se-pickling, ngenxa yesenzo samaqembu awo angenawo umoya, kwakha ungqimba lwefilimu oluqondile olunganyibiliki ebusweni besisombululo se-pickling. Ngokusebenzisa isenzo se-foam sama-surfactants, i-acid inkungu yokuguquguquka ingacindezelwa. Yiqiniso, ama-corrosion inhibitors avame ukungezwa kuzixazululo ze-pickling, okunciphisa kakhulu izinga lokugqwala kwensimbi futhi kunciphisa ukuvela kwe-hydrogen, ngaleyo ndlela kunciphisa inkungu ye-acid ngokufanayo.
2 Njengokuhlanza Okuhlanganisiwe Kokukhuhla Nokususa Amafutha
Ngokuvamile ekuhlanzweni kwamakhemikhali emishini yezimboni, uma ukungcola kuqukethe izingxenye zikawoyela, ukuhlanzwa kwe-alkaline kuqala kwenziwa ukuqinisekisa ikhwalithi yokuhlanza, kulandelwe ukuhlanzwa kwe-asidi. Uma inani elithile le-ejenti yokususa amafutha, ikakhulukazi ama-surfactants angewona ama-ionic, lifakwa esixazululweni sokuhlanza, izinyathelo ezimbili zingahlanganiswa zibe yinqubo eyodwa. Ngaphezu kwalokho, izixazululo eziningi zokuhlanza eziqinile ziqukethe i-sulfamic acid futhi ziqukethe inani elithile lama-surfactants, i-thiourea, kanye nosawoti we-inorganic, axutshwe ngamanzi ngaphambi kokusetshenziswa. Lolu hlobo lwe-ejenti yokuhlanza alugcini nje ngokuba nezakhiwo ezinhle kakhulu zokususa ukugqwala kanye nezikali kanye nokuvimbela ukugqwala kodwa futhi lususa uwoyela ngasikhathi sinye.
