Ipleyiti yealuminiyam enepateni sisixhobo sokwakha esiqhelekileyo, kwaye inkqubo yayo yahlulwe ikakhulu yangamacandelo amathathu: i-de-esterification, ilitye lokusila, kunye nokuhlamba amanzi.Phakathi kwabo, ukuhlamba amanzi yinkqubo ebaluleke kakhulu.Ukuze kuqinisekiswe umgangatho womphezulu kunye nomgangatho we-welding ye-aluminiyam ipleyiti, amanyathelo okucoca angqongqo kufuneka athathwe ukuze asuse ngokucokisekileyo igrisi kunye nefilimu ye-oxide kumphezulu wepleyiti ye-aluminium kunye namalungu adibeneyo.Ngoko ukucoca njani ipleyiti ye-aluminium ebrashiweyo?
1. Ukucocwa komatshini: Xa ubukhulu bomsebenzi bukhulu, umjikelezo wokuvelisa ude, kwaye ungcolisekile emva kweereyile ezininzi okanye ukucocwa kweekhemikhali, ukucocwa komatshini kusetyenziswa rhoqo.Okokuqala sula umphezulu nge-acetone, i-petroli kunye nezinye izinyibilikisi ze-organic ukususa i-oyile, kwaye usebenzise ngokuthe ngqo ibrashi yocingo lobhedu okanye ibrashi yocingo engenastainless kunye nobubanzi obuyi-0.15mm~0.2mm de kuvele i-metallic luster.Ngokuqhelekileyo, akucebisi ukusebenzisa ivili lokugaya okanye i-sandpaper eqhelekileyo yokuthungatha, ukwenzela ukuthintela amaqhekeza entlabathi ukuba ahlale kwindawo yesinyithi kunye nokungena echibini elityhidiweyo ngexesha lenkqubo yokudweba ucingo ukuze kubangele iziphene ezifana nokufakwa kwe-slag.
Ukongeza, i-scrapers, iifayile, njl.Emva kokuba i-workpiece kunye nenkqubo ihlanjululwe kwaye ihlanjululwe, ifilimu ye-oxide iya kuhlaziywa ngexesha lokugcinwa, ngokukodwa kwindawo enomswakama, kwindawo engcolileyo nge-asidi, i-alkali kunye neminye imiphunga, ifilimu ye-oxide iya kukhula ngokukhawuleza.Ngoko ke, ixesha lokugcina i-workpiece kunye nomzobo wocingo emva kokucoca kunye nokucoca ukuya kuthi ga ngaphambi kokuba umzobo wocingo ucuthwe kangangoko kunokwenzeka.Ngokuqhelekileyo, umzobo wocingo kufuneka wenziwe kwiiyure ezi-4 emva kokucoca kwindawo epholileyo.Emva kokucoca, ukuba ixesha lokugcina lide kakhulu (ngaphezu kwe-24h), kufuneka liqhutyelwe kwakhona.
2. Ukucoca iikhemikhali: ukucocwa kweekhemikhali kunokusebenza okuphezulu kunye nomgangatho ozinzile.Inkqubo yokudweba ucingo ifanelekile ukucoca ubungakanani obuncinci kunye ne-batch-produced workpieces.Iindidi ezimbini zendlela yokudipha kunye nendlela yokukhuhla ziyafumaneka.Sebenzisa i-acetone, i-petroli, i-kerosene kunye nezinye izinyibilikisi ze-organic ukuze unciphise umphezulu.Sebenzisa isisombululo se-5% ~ 10% se-NaOH kwi-40 ℃ ~ 70 ℃ ukuhlamba i-3min ~ 7min (ixesha elicocekileyo le-aluminiyam lide kancinane kodwa alikho ngaphezu kwe-20min), hlambulula ngamanzi aqukuqelayo, kwaye usebenzise iPickling nge-30% isisombululo se-HNO3 ubushushu begumbi ukuya kwi-60 ℃ nge-1min ~ 3min, hlambulula ngamanzi abalekayo, umoya owomileyo okanye owomileyo ophantsi.
Oku ngasentla yindlela yokucoca ipleyiti ye-aluminium exutywe.Amanyathelo okucoca ipleyiti ye-aluminiyam exutywe zizinto ezisisiseko.Emva koko, inkqubo yokudweba ingaba namandla kwaye umgangatho wemveliso ogqityiweyo unokuba ngcono.
