Uma kuqhathaniswa nezinqubo ezifana ne-plating kanyeukwelashwa kwendawo, ukuhlanza kubonakala kuyisinyathelo esingasho lutho.Iningi lenu lingase lingacabangi ukuhlanza ukutshalwa kwezimali okunenzuzo, ngoba ukuhlanza kubiza kuphela isikhathi nemali.Kodwa empeleni, ukuhlanza kubalulekile kwikhwalithi yomkhiqizo futhi kunomthelela omkhulu enqubweni elandelayo.Kuyadingeka ukuhlaziya izizathu zokuthi kungani ukuhlanza kubaluleke kangaka.
Ngaphambi kokwelashwa kokushisa, ingaphezulu le-workpiece ngokuvamile libukeka lihlanzekile futhi alinawo amaphutha ekuhlolweni okubonakalayo.Kodwa-ke, ezinqubweni emva kokwelashwa kokushisa (njenge-nitriding), izinkinga ezibangelwa ukuhlanzeka kwendawo esezingeni eliphansi zivezwa.Ukusetshenzwa kabusha kwemikhiqizo enesici kuyabiza ngokwesikhathi nemali, futhi imikhiqizo enesici ayikwazi ukusetshenzwa kabusha ezikhathini eziningi.
Uma kwenzeka kuba nenye yezinkinga ezinjalo, kufanele siphenye izimbangela ngokushesha okukhulu.Izimbangela zemishini nemishini kufanele zihlolwe kuqala: uhlobo lwempahla, ukwakheka kwezingxenye, inqubo yesithando somlilo se-nitriding, nokucubungula ngomshini.Uma lezi zici zingagwenywa, ukukhubazeka kuvame ukubangelwa ungqimba olungabonakali lokuvimbela ukusabalalisa ebusweni bomsebenzi wokusebenza, okusho ukuthi okunye okusele endaweni ehlanzekile ebonakalayo ebangela iphutha.
Ngaphambi kokwelashwa okushisa, ingxenye idlula izinqubo eziningi, okuholela ekushintsheni kwendawo.Kunezinhlobo ezimbili eziyinhloko zezinguquko.
Izinguquko zemishini: ukuguqulwa;i-extrusion;ukugaya.
Izinguquko zamakhemikhali: izingqimba ze-phosphate (isb. i-zinc phosphating ukusiza ekudwebeni);ama-anti-corrosion compounds;i-chlorine, i-phosphorus noma isulfure ingase iqukethwe ku-lubricant yokupholisa, i-saponification fluid, uwoyela nezinye izithasiselo;i-reagent yokutholwa kokuqhekeka kwendawo.
Indlela yokuhlanza i-workpiece ukuze uqinisekise ukuhlanzeka kwendawo?
Ngokuvamile amanzi angu-95-99% ane-ejenti yokuhlanza engu-1-5% asetshenziselwa ukuhlanza i-workpiece, futhi ikhwalithi yamanzi ibaluleke kakhulu.Ukungcola emanzini okufana ne-calcium, i-magnesium, i-sodium, i-potassium, ne-chloride kungahlala phezu kwendawo yokusebenza ngemva kokoma ukuze kwakhiwe umgoqo wokusabalalisa, ngakho-ke amanzi akhishwe nge-deionized ane-conductivity efika ku-50 µS/cm kufanele asetshenziselwe ukuvimbela. izinkinga ngesikhathi sokuhlanza.
Uhlelo lokuhlanza ngamanzi luqukethe izinhlobo ezimbili zezingxenye: i-ejenti yokuhlanza eyinhloko kanye ne-ejenti esebenzayo engaphezulu.
I-ejenti yokuhlanza eyinhloko: Iqukethe izinto ezingaphili noma eziphilayo, njenge-alkali, i-phosphate, i-silicate, ne-amine.Ingakwazi ukulungisa i-pH, inikeze ukuqhutshwa kukagesi, kanye ne-saponify grease.
I-ejenti esebenzayo ebusweni: Iqukethe izinto eziphilayo, njenge-alkyl benzene sulfonates kanye ne-fatty alcohol ethoxylates, futhi idlala indima yokuncibilikisa nokusabalalisa amafutha namafutha.
Imingcele emine ebalulekile yokuhlanza ngamanzi ukuhlanza uketshezi, isikhathi sokuhlanza, izinga lokushisa lokuhlanza kanye nendlela yokuhlanza.
1. Uketshezi lokuhlanza
Uketshezi lokuhlanza kufanele luvumelane nengxenye (uhlobo lwezinto ezibonakalayo), ukungcola kwamanje nokulandelayoukwelashwa kwendawo.
2. Isikhathi sokuhlanza
Isikhathi sokuhlanza sincike ohlotsheni kanye nenani lokungcola futhi singancika ekulandeleni okunikezwayo komugqa wokuhlanza ukuze ungaphazamisi izinyathelo zomsebenzi ezilandelayo.
3. Ukuhlanza izinga lokushisa
Ukushisa okuphezulu kokuhlanza kuzonciphisa i-viscosity yamafutha futhi kuncibilike amafutha, okwenza kube lula futhi kube lula ukususa lezi zinto.
4. Indlela yokuhlanza
Imisebenzi ehlukene yethulwa ngemishini yokuhlanza, njengokuthi: ukujikeleza kwethangi, ukuchichima, ukufutha, kanye ne-ultrasonic.Indlela yokuhlanza incike ohlotsheni nokuma kwengxenye, ukungcola kanye nesikhathi sokuhlanza esitholakalayo.
Lezi zinhlaka ezine kufanele zilungiswe ukuze zibe nesimo sangempela.Ukunikezwa kwamandla amaningi (imishini, eshisayo noma yamakhemikhali) noma isikhathi eside sokwelashwa sizothuthukisa umphumela wokuhlanza.Ngaphezu kwalokho, ukugeleza okunamandla kokuhlanza uketshezi kuzothuthukisa umphumela wokuhlanza emazingeni okushisa aphansi.
Kuyaqapheleka ukuthi ezinye zezinto ezingcolisayo ziboshwe kahle kakhulu futhi azikwazi ukususwa ngokuhlanza.Ukungcola okunjalo kuvame ukususwa kuphela ngezinqubo ezinjengokugaya, ukuqhunyiswa kwesihlabathi, kanye ne-pre-oxidation.
