Ipuleti le-aluminium elinephethini liyinto evamile yokwakha, futhi inqubo yalo ihlukaniswe ikakhulukazi izingxenye ezintathu: i-de-esterification, isigayo sesihlabathi, nokugeza amanzi.Phakathi kwabo, ukugeza amanzi kuyinqubo ebaluleke kakhulu.Ukuze kuqinisekiswe ikhwalithi engaphezulu kanye nekhwalithi yokushisela yepuleti le-aluminium, izinyathelo eziqinile zokuhlanza kufanele zithathwe ukuze kususwe ngokuphelele ifilimu yegrisi ne-oxide ebusweni bepuleti le-aluminium kanye namajoyinti ashiselwe.Ngakho-ke ungayihlanza kanjani ipuleti le-aluminium elixutshwe?
1. Ukuhlanza ngomshini: Uma ubukhulu bomsebenzi omkhulu, umjikelezo wokukhiqiza umude, futhi ungcolile ngemva kwezendlalelo eziningi noma ukuhlanzwa kwamakhemikhali, ukuhlanza ngomshini kuvame ukusetshenziswa.Okokuqala sula ingaphezulu nge-acetone, uphethiloli nezinye izincibilikisi eziphilayo ukuze ususe uwoyela, bese usebenzisa ngokuqondile ibhulashi lentambo yethusi noma ibhulashi lensimbi engagqwali elinobubanzi obungu-0.15mm~0.2mm kuze kube yilapho ukucwebezela kwensimbi kudaluliwe.Ngokuvamile, akufanelekile ukusebenzisa isondo lokugaya noma i-sandpaper evamile ekuthungeni isihlabathi, ukuze uvimbele izinhlayiya zesihlabathi ukuthi zingahlali phezu kwensimbi futhi zingene echibini elincibilikisiwe phakathi nenqubo yokudweba ucingo ukuze kubangele ukukhubazeka okufana nokufakwa kwe-slag.
Ngaphezu kwalokho, ama-scrapers, amafayela, njll angasetshenziswa futhi ukuhlanza ubuso obuzofakwa.Ngemuva kokuthi i-workpiece nenqubo ihlanjululwe futhi ihlanzwe, ifilimu ye-oxide izovuselela ngesikhathi sokugcinwa, ikakhulukazi endaweni enomswakama, endaweni engcoliswe i-asidi, i-alkali namanye ama-vapors, ifilimu ye-oxide izokhula ngokushesha.Ngakho-ke, isikhathi sokugcina se-workpiece kanye nomdwebo wocingo ngemuva kokuhlanza nokuhlanza kuze kufike ngaphambi kokudweba ucingo kufanele sifinyezwe ngangokunokwenzeka.Ngokuvamile, umdwebo wezintambo kufanele wenziwe phakathi kwamahora angu-4 ngemva kokuhlanza esimweni sezulu esinomswakama.Ngemuva kokuhlanza, uma isikhathi sokugcina siside kakhulu (ngaphezu kuka-24h), kufanele sicutshungulwe futhi.
2. Ukuhlanza amakhemikhali: ukuhlanza amakhemikhali kunokusebenza okuphezulu kanye nekhwalithi ezinzile.Inqubo yokudweba ngocingo ilungele ukuhlanza ama-workpieces akhiqizwe ngosayizi omncane kanye neqoqo.Izinhlobo ezimbili zendlela yokucwilisa kanye nendlela yokukhuhla ziyatholakala.Sebenzisa i-acetone, uphethiloli, uphalafini nezinye izincibilikisi eziphilayo ukuze unciphise ingaphezulu.Sebenzisa isixazululo se-NaOH esingu-5% ~ 10% ku-40 ℃~70 ℃ ukugeza imizuzu engu-3 ~ 7min (isikhathi se-aluminium ehlanzekile siside kancane kodwa asibi ngaphezu kwama-20min), hlambulula ngamanzi agelezayo, bese usebenzisa i-Pickling nge-30% isixazululo se-HNO3 at izinga lokushisa lekamelo liye ku-60 ℃ i-1min ~ 3min, hlambulula ngamanzi agijimayo, ukomisa umoya noma ukomisa izinga lokushisa eliphansi.
Okungenhla kuyindlela yokuhlanza yepuleti le-aluminium elixutshwe.Izinyathelo zokuhlanza zepuleti le-aluminium ebhulashiwe yizona eziyisisekelo.Phela, inqubo yokudweba ingaba namandla futhi ikhwalithi yomkhiqizo ophelile ingaba ngcono.
