Isivuno se-oxidation sisivuno semveliso enye, oko kukuthi, isivuno semveliso enye ngaphandle kokuphinda kusetyenzwe.Ngokwenkqubo yokuvelisa, iindleko zeeprofayili ezihlaziyiweyo ziphindwe kathathu kwiiprofayili ezingaphindanga ziphinde zenziwe, kwaye umgangatho ophezulu weeprofayili awukwazi ukuqinisekiswa.Ngokuqinisekileyo, umgangatho weemveliso ze-oxidized uqala kwi-workshop yokuphosa.Ngenxa yezithintelo zendawo, oku kulandelayo yintetho emfutshane malunga neenkcukacha ezithile ekufuneka ziqwalaselwe kwinkqubo yokuvelisa i-oxidation.
I-screw phakathi kwentonga yokuxhoma kunye ne-conductive beam kufuneka iqiniswe rhoqo.Ngaphambi kokubopha izinto eziphathekayo, kufuneka siqale sihlolisise ukuba intonga yokuxhoma igxininisekile.Ukuba ikhululekile kancinane, kufuneka iqiniswe ngexesha.Enye i-corrosion, intonga yokuxhoma iya kuba yincinci, idinga ukutshintshwa ngexesha, kuba indawo yayo yokuhambisa incinci, kulula ukubangela ukushisa, kwangaxeshanye ukubopha, ukukhusela Iprofayili ewela kwi-slot ebangelwa yipali, umonakalo omfutshane wesiphaluka kunikezelo lwamandla.
Kwangaxeshanye iwele kwiprofayile yetanki kufuneka icocwe kwangexesha, njengetanki yokuhlamba yealkali ibe yiprofayile, iya kuhlwa kungekudala, uvavanyo lubonakalise ukuba ukusetyenziswa kwealkali kuyalingana nokuhlamba kwealkali kwe50-100. ingcambu yeprofayili yokusetyenziswa kwe-alkali.Ukuwela kwitanki yombala okanye itanki yokutywina, ngenxa yokubola, itanki iya kuqokelela inani elikhulu le-ion aluminium, echaphazela ubomi benkonzo ye-tank liquid.
Izinto zokubopha ngocingo lwe-aluminiyam kunye neentlobo ezimbini zenkcazo zilungile, i-aniseed yokukhetha ucingo lwe-aluminiyam olurhabaxa, imathiriyeli ephakathi kunye nencinci isetyenziselwa i-aluminium ecikizekileyo, ingasetyenziselwa i-2mm kunye ne-3mm, okanye i-2.2mm kunye ne-3.2mm iindidi ezimbini zenkcazo, i-aluminium. ukuqina kocingo lokuvala kuthatha i-1/2~3/4 kulungile.Okwangoku, amashishini amaninzi aguqulelwe kwijig.
Ngaphambi kokuxhoma kwitanki ye-oxidation ukuze uqinise iprofayili nganye; Izinto zokuphinda zisebenze phambi kwe-oxidation yezinto eziphathekayo, ukusebenzisa i-pliers ukubetha isiphelo seprofayili ukwenza i-shift phambi kwezinto, ukuze uqhagamshelwano ngaphandle kwefilimu, ukuqinisekisa ukuhanjiswa okulungileyo. .
Chwetheza imathiriyeli ejinga kwitanki oxidation kunye netanki yombala isihlalo conductive kufuneka ingqalelo ekunene, kungenjalo ethambekele kwi Yin kunye Yang ibala umahluko.
Emva kokuba isiphelo samandla e-oxidation sinqunyanyisiwe ngexesha, ukuhlala kwitanki ye-oxidation imizuzu embalwa kuya kuchaphazela umngxuma wokutywina, kuya kwenza isantya sombala;Emva kwe-oxidation, iyaphakanyiswa kwaye ithotywe emoyeni ixesha elide.Esinye isiphelo sesisombululo sokunciphisa i-asidi simnyama ngenxa yokwandiswa kwepore yefilimu ye-oxide, kwaye umehluko wombala kuzo zombini iziphelo kulula ukuvela.
Ixabiso le-pH lamatanki okuhlamba amanzi amane ngaphambi nangemva kwetanki yombala kufuneka igcinwe ngokuzinzileyo.Ixabiso le-pH lamatanki amane okuhlamba amanzi aqhelekileyo alawulwa ngolu hlobo lulandelayo:
Ixabiso le-pH lokuhlambela kwamanzi okuqala emva kwe-oxidation: 0.8 ~ 1.5
Ixabiso le-pH lesibini lokuhlambela amanzi emva kwe-oxidation: 2.5 ~ 3.5
Ixabiso le-pH lokuhlambela kwamanzi okuqala emva kombala: 1.5 ~ 2.5
Ixabiso le-pH yetanki yesibini yokuhlamba emva kombala: 3.5 ~ 5.0
Kwiimeko eziqhelekileyo, umlinganiselo othile wamanzi aphuphumayo uvulwa ngexesha lokuvelisa, kwaye i-valve yokungena ivaliwe ngexesha xa ukuveliswa kumisiwe.Akufunekanga ikhuphe amanzi okanye yongeze amanzi kwitanki yonke.Ukuba amanzi ahlala kwi-tank yokuqala yokuhlamba emva kwe-oxidation imizuzu embalwa, isantya sombala siya kukhawuleza, kwaye ukuba amanzi ahlala kwi-tank yesibini yokuhlamba, umbala uya kuncipha.
Ukuveliswa kwezixhobo zentsimbi ezikhanyayo, indlela yombala iyamkelwa ngokubanzi kuqala, emva koko ibuyele kwipleyiti yombala eqhelekileyo.Ngenxa yokwahlukana kombala wentsimbi yokulinganisa ixesha lokulawula ixesha lincinci kakhulu (imizuzwana emi-2 ~ 3 kuphela) , kwaye ukusebenzisa umgaqo ophelayo unokuba ne-10 ~ 15 imizuzwana yexesha lokulawula umbala, kwaye ukufiphala okudityanisiweyo kukwanceda kumbala ongasemva ofanayo, ukulinganisa intsimbi ephelayo kunye nemibala ehambelanayo inombala ithande ukujika luhlaza, kwaye umbala wexesha elinye uthande ukujika. ibebomvu.
Uhlobo lwezinto ezixhonywe kwitanki yombala kunye netanki yokuqala yokuhlamba emva kokufakwa kwemibala emva kokuxhoma musa ukuyeka ixesha elingenanto lide kakhulu, kungenjalo umphezulu weprofayili uya kuvela irebhoni, umbala ongalinganiyo kunye nokuphela komlambo wento emhlophe, kufuneka ibe kancinci kumbala we ukuhlamba okulandelayo ngexesha, umbala oluchanekileyo kufuneka kuhlanjwe yesibini emva.Ngokuthetha ngokubanzi, izinto zentsimbi ukulinganisa, ezifana template umahluko umbala obomvu, ibonisa ukuba ixesha imibala akwanelanga ukuba umphelelisi umbala; Ukuba umbala omthubi. , ifakwe umbala, ngokobunzulu bombala, ungakhetha ukuhlehla kwitanki yombala okanye kwitanki yokuqala yokuhlamba emva kombala.
Indlela yokongeza iziyobisi kwitanki yombala: i-sulfate ye-stannous kunye ne-nickel sulfate kufuneka ichithwe kwitanki, kwaye isongezo sombala kufuneka sinyibilike emanzini acocekileyo (amanzi acocekileyo ayanyibilika).Kufuneka kuqatshelwe ukuba isongezelelo esiqinileyo sinokugalelwa emva kokuchithwa ngokupheleleyo, kwaye i-asidi ye-sulfuric concentrated ingagalelwa ngqo kwitanki yombala.
Ubushushu, ixesha kunye nomgangatho wamanzi okuhlamba amanzi ashushu phambi kokuba i-electrophoresis iqinisekiswe.Ukuba intsalela ye-SO42- kumngxuma wefilimu ye-oxide ayihlanjwanga, ukutyheli kunye ne-opacity yefilimu yepeyinti kunokwenzeka ukuba yenzeke emva kwe-electrophoresis kunye nokubhaka.Phantsi kweemeko eziqhelekileyo, ubushushu bamanzi ashushu bulawulwa kwi-60 ~ 70 ℃, kunye nokuhlamba kwamanzi ashushu. ixesha yi 5 ~ 10 imizuzu.
