Inkinga yokuhlanza ye-fasteners yamandla aphezulu ivame ukubonakaliswa ngemva kokwelashwa kokushisa nokushisa, futhi inkinga enkulu ukuthi ukuhlanza akuhlanzekile. Ngenxa yokunqwabelana ngokungafanele kwezinsimbi, i-lye ihlala phezulu, yenze ukugqwala okungaphezulu nokushiswa kwe-alkali, noma ukukhetha okungafanele kukawoyela wokucisha kwenza ukugqwala kwe-fastener surface.
1. Ukungcola okukhiqizwa ngesikhathi sokuwasha
Ngemuva kokucima, izinsimbi zihlanzwa nge-agent yokuhlanza i-silicate bese zihlanjululwa. Izinto eziqinile zivele phezulu. Izinto ezisetshenziswayo zahlaziywa nge-infrared spectrometer futhi kwaqinisekiswa ukuthi ayi-inorganic silicate ne-iron oxide. Lokhu kungenxa yensalela ye-silicate endaweni yokubopha ngemva kokugeza okungaphelele.
2. Ukupakishwa kwama-fasteners akufanelekile
Ngemuva kokuthi izinsimbi ezishisayo zibonise izimpawu zokushintsha umbala, cwilisa nge-ether, vumela i-ether ivuthe futhi ithole izinsalela ezinamafutha, izinto ezinjalo zinokuqukethwe okuphezulu kwe-lipids. Kubonisa ukuthi izinto zokubopha zingcoliswe ama-agent okuhlanza kanye namafutha okucisha ngesikhathi sokuhlanza, ancibilika ekushiseni kokushisa futhi ashiye izibazi ezivuthayo zamakhemikhali. Izinto ezinjalo zibonisa ukuthi i-fastener surface ayihlanzekile. Ihlaziywa nge-spectrometer ye-infrared, iyingxube yamafutha ayisisekelo kanye ne-ether kuwoyela wokucisha. I-ether ingase ivele ekufakweni kwamafutha okucisha. Imiphumela yokuhlaziywa kwamafutha okucisha esithandweni somlilo sebhande le-mesh iqinisekisa ukuthi ama-fasteners ane-oxidation encane emafutheni okucima ngenxa yokupakisha okungenangqondo ngesikhathi sokushisa, kodwa cishe akunakwa. Lesi simo sihlobene nenqubo yokuhlanza, kunenkinga yamafutha okucisha.
3. Izinsalela zobuso
Izinsalela ezimhlophe kusikulufa samandla aphezulu zahlaziywa nge-infrared spectrometer futhi zaqinisekiswa ukuthi ziyi-phosphide. Ayikho i-ejenti yokuhlanza i-asidi esetshenzisiwe ukuhlanza ithangi lokuwasha, futhi ukuhlolwa kwethangi lokuwasha kwathola ukuthi ithangi line-carbon solubility ephezulu. Ithangi kufanele lithululwe njalo, futhi izinga lokuhlushwa le-lye ethangini lokuhlanza kufanele lihlolwe njalo.
4. Ukushiswa kwe-alkali
Isikulufu samandla aphezulu esicisha ukushisa okuyinsalela mnyama kuneyunifomu, indawo yangaphandle yamafutha abushelelezi emnyama. Kodwa endandeni yangaphandle kunendawo ebonakalayo ewolintshi. Ngaphezu kwalokho, kunezindawo eziluhlaza okwesibhakabhaka noma ezibomvu ezikhanyayo.
Kutholwe ukuthi indawo ebomvu esikulukweni ibangelwa ukusha kwe-alkali. I-ejenti yokuhlanza i-alkaline equkethe ama-chloride nezinhlanganisela ze-calcium izoshisa izibophelelo zensimbi ngesikhathi sokwelashwa kokushisa, ishiye amachashaza ebusweni bezinsimbi.
I-alkalinity engaphezulu yezinsimbi zensimbi ayikwazi ukususwa emafutheni wokucisha, ukuze ingaphezulu lishise ekushiseni okuphezulu kwe-austenite futhi kukhulise ukulimala esinyathelweni esilandelayo sokuthulisa. Kunconywa ukuthi ugeze futhi uhlanza izinsimbi kahle ngaphambi kokwelashwa kokushisa ukuze ususe ngokuphelele izinsalela ze-alkaline ezibangela ukushiswa kwezinsimbi.
5. Ukugeza okungafanele
Kuma-fasteners amakhulu, i-polymer aqueous solution quenching ivame ukusetshenziswa. Ngaphambi kokucisha, i-alkaline yokuhlanza i-ejenti isetshenziselwa ukuhlanza nokuhlanza izinsimbi. Ngemva kokucisha, ama-fasteners agqwalile ngaphakathi. Ukuhlaziywa ngama-spectrometers we-infrared kuqinisekisile ukuthi ngaphezu kwe-iron oxide, kukhona i-sodium, i-potassium nesibabule, okubonisa ukuthi i-fastener inamathele ngaphakathi kwe-ejenti yokuhlanza i-alkali, mhlawumbe i-potassium hydroxide, i-sodium carbonate noma izinto ezifanayo, ikhuthaza ukugqwala. Ukuwasha nge-fastener kuhlolelwa ukungcoliswa ngokweqile futhi ukushintshwa njalo kwamanzi okugeza kuyanconywa. Ngaphezu kwalokho, ukwengeza i-rust inhibitor emanzini nakho kuyindlela enhle.
