I-HOT-dip-dip ye-dipvaningyindlela esetyenzisiweyo esetyenziswayo yokukhusela intsimbi kunye nentsimbi ukusuka kwi-corrosion. Le nkqubo ibandakanya ukuntywilisela isinyithi ekubhateni i-nyibinc ye-zunc, eyenza i-gooust, ikhuselayo. Isinyithi esikhutshelwe isinyithi esixhaphakileyo sixhathise kakhulu kwi-rust kwaye siyakwazi ukumelana neemeko zengozi engqongqo. Nangona kunjalo, ukufezekisa iziphumo ezigqibeleleyo kufuna ukubambelela kwiimfuno ezithile kunye neendlela ezilungileyo. Eli nqaku lihlala liphelisa kwiimfuno ezibalulekileyo ze-DAP-dip ye-dipvaning yokuqinisekisa iziphumo ezisemgangathweni ezisemgangathweni kunye neziqinisekileyo.
1. Ukukhetha izinto
Imfuneko yokuqala ye-DAP-dip ye-Dage-I-DEP ye-DATE kukhetho lwezinto ezifanelekileyo. Ayizizo zonke iintsimbi ezifanelekileyo kule nkqubo. Ngokwesiqhelo, intsimbi kunye nentsimbi ngabagqatswa baphambili. Ukuqulunqwa kwesinyithi kunokuchaphazela kakhulu umgangatho wei-galvaning. Umzekelo, ubukho bezinto ezinjengeSilicon kunye ne-phosphorus kwintsimbi zinokuphembelela ubukhulu nenkangeleko ye-zinc. Ke ngoko, kubalulekile ukukhetha izixhobo ngezixhobo ezilawulwayo nezisaziwayo ukufezekisa iziphumo ezingaguqukiyo.
2. Ukulungiswa komphezulu
Ukulungiselela umphezulu linyathelo elibalulekileyo kwiI-HOT-dip-dip ye-dipvaninginkqubo. Umphezulu wensimbi kufuneka ucoceke kwaye ungabi nazingcongconi ezifana neoyile, igrisi, irhamncwa, kunye nesilima. Nakuphi na ukungcola kunokuthintela i-zinc ukusuka ngokubhekisele ekuthobeleni ngokufanelekileyo, kukhokelela kumgangatho ophantsi obandayo. Ukulungiselela umphezulu kubandakanya amanqanaba amathathu:
- Ukukhutshwa: Ukususwa kwee-organic zongcoliseko kusetyenziswa izisombululo ze-alkaline okanye izinyibilikisi.
- Ukuthathwa: Ukususwa kwe-rump kunye nenqanaba usebenzisa izisombululo ze-acidic, zihlala ze-hydrochloric okanye i-sulfuric acid.
- Isisombululo: Ukusetyenziswa kwesisombululo se-flux, rhoqo i-zinc ammonium hloride, ukuthintela i-oxidation ngaphambi kokuntywila kwi-molten zinc.
Ukulungiselela umphezulu ofanelekileyo kuqinisekisa ubudlelwane obuqinileyo phakathi kwesinyithi kunye ne-zinc cais, ukwandisa ukuqina kunye nokusebenza kwe-GARMAN.
I-3. Ukuqulunqwa kokuhlamba kunye nobushushu
Ukuqulunqwa kunye nobushushu bebhafu zeZinc zizinto ezibaluleke kakhulu kwinkqubo ye-DIP ye-DAP ye-DAGE. Ibhafu ye-zinc kufuneka ibe ne-98% ye-zinc, ipesenti eseleyo efana ne-aluminium, ukukhokela, kunye ne-antimony yokuphucula iipropathi zomsebenzi. Iqondo lokushisa lokuhlambela lihlala liphakathi kwe-820 ° F kunye ne-860 ° 2,38 ° C ukuya kwi-460 ° 2 ° C). Ukugcina ubushushu obuchanekileyo kubalulekile ekufezekiseni iyunifomu kunye ne-Coades esemgangathweni esemgangathweni ephezulu. Ukuphambuka kunokukhokelela kwiziphene ezifana nobungqingqwa obungalinganiyo, ukunamathela olihlwempu, kunye nobunzima obuphakathi.
4. Ixesha lokuntywila
Ixesha lokuntywila kwibhafu zeZinc yenye iparameter ebalulekileyo. Kuxhomekeka kubunzima kunye nobungakanani beintsimbi ye-gazinionaliwe. Ngokubanzi, isinyithi singenelwa de sifikelele kubushushu bebhafu, sivumela i-zinc ukuba yenze ingqokelela ye-metric kunye nentsimbi. Ukuntywila okungaphezulu kunokukhokelela ekubeni nobungqingqwa obugqithisileyo, ngelixa uxinzelelo lungakhokelela kukhuseleko olungafaneleki. Ke ngoko, ukulawulwa ngokuthe ngqo kwexesha lokuntywila kubalulekile ukufezekisa ubukhulu obufumileyo kunye nomgangatho.
5. Unyango lwePosi
Emva kokuba intsimbi isuswe kwiI-Zinc Bath, iphantsi kweendlela zokunyanga emva kwe-galvaning ukonyusa iipropathi zomxholo. Olu nyango lunokubandakanya ukucingela emanzini okanye ngomoya ukupholisa ukuqinisa i-zinc caid ngokukhawuleza. Ukongeza, unyango lwe-pluvation lunokusetyenziswa ukuthintela ukwakhiwa kwe-rust emhlophe, uhlobo lwe-corrosion enokuthi yenzeke kwindawo entsha. Ukuphatha ngokufanelekileyo kunye nokugcinwa kwezinto ezisetyenziswayo kubalulekile ukugcina ingqibelelo.
6. Uvavanyo kunye nolawulo oluphambili
Okokugqibela, uhlolo olufanelekileyo kunye nolawulo oluphambili lubalulekile ukuqinisekisa impumelelo yeI-HOT-dip-dip ye-dipvaninginkqubo. Ukuhlolwa ngokwesiqhelo kubandakanya uvavanyo olubonakalayo, imilinganiselo yobunzima, kunye neemvavanyo zokuhlaselwa. Imigangatho efana ne-ASTM A123 / i-A123M ibonelela ngesikhokelo sobukhulu obamkelekileyo kunye nomgangatho. Ukuthobela le migangatho kuqinisekisa ukuba iimveliso ze-galvanition ziyahlangabezana neekhrayitheriya zentsebenzo ezifunekayo kwaye zinike ukhuseleko oluhlala ixesha elide ngokunyanzelwa.
Ukuqukumbela
I-datvaning eshushu yindlela esebenzayo yokukhusela intsimbi kunye nesinyithi ukusuka ekususweni, kodwa ifuna ingqalelo efanelekileyo kwiinkcukacha kunye nokubambelela kwiinkcukacha ezithile. Ukusuka ekukhetheni izinto ezibonakalayo kunye nokulungiselela umphezulu kubume bokuhlamba, ixesha lokuntywila, kunye nokunyanga emva kokusebenza, inyathelo ngalinye lidlala indima ebalulekileyo ekufezekiseni intambo ekumgangatho ophezulu kunye neyemigangatho eqinileyo. Ngokulandela le misebenzi ilungileyo kunye nokugcina ulawulo oluqhelekileyo lomgangatho, abavelisi banokuqinisekisa ukuba iimveliso zabo ze-galvanisiwe zizisa intsebenzo elunge ngakumbi kunye nobomi obugqibeleleyo.
