Cov txheej txheem tinnones bolts

Tin yog silvery dawb hlau, tsis-lom, nrog weldability zoo thiab ductility. Nws yog dav siv nyob rau hauv electronics, zaub mov, tsheb thiab lwm yam kev lag luam. Cov txheej txheem tinning ntawm hexagonal bolts yog cais los ntawm cov kev cog lus ntawm cov plating, uas tau muab faib ua ob pawg: acidic plating txheej txheem thiab cov txheej txheem sinning.
Qhov kom zoo dua ntawm cov kua qaub yog nrawm dua plating ceev. Cov txheej yog ci thiab muag heev, thiab lub peev xwm sib sib zog nqus yog qhov zoo. Cov kev daws teeb meem tau muaj zog tiv thaiv kom tsis txhob txwm, thiab cov haujlwm hnyav txuag txuag lub zog. Qhov tsis zoo yog tias qhov kev daws teeb meem ntawm cov plating txheej yog qhov tsis zoo, lub crazing tsis zoo li alkaline tinning, thiab cov tin yog hydrolyzed. Cov kua qaub tinning ntawm hexagonal bolts tau faib ua sulfate tinning sinning, chloride tinning thiab lwm cov txheej txheem vim muaj kev tshaj tawm sib txawv.
Sulphuric acid tinning muaj tus nqi qis, yooj yim los tswj cov plating daws, ci ntsa iab thiab kev ua tsis tau zoo, tab sis txom nyem tsis zoo. Nws yog qhov feem ntau dav siv nyob rau hauv kev ua lag luam. Qhov zoo ntawm fluobonite fluobield tinning nrawm nrawm, loj tam sim no tuaj yeem siv, thiab cov kev daws teeb meem tau muaj kev ruaj khov zoo. Nws yog dav siv nyob rau hauv tas mus li electroplating ntawm flange ceev, xaim thiab ib daim hlab. Qhov tsis zoo yog tus nqi siab ntawm cov kev daws teeb meem, muaj txiaj ntsig siab, thiab kev nyuaj thiab kev kho kom muaj dej khib nyiab.
Chloride Tinning feem ntau yog siv rau crystal tinning. Qhov zoo yog tus nqi qis, ruaj khov plating daws, thiab dawb txheej. Qhov tsis zoo yog tias tam sim no tsis tuaj yeem qhib ntau dhau. Qhov zoo ntawm alkaline tinning ntawm hexagonition bolts yog: zoo disating ntawm plating daws, zoo txheej, thiab kev ua tau zoo. Qhov tsis zoo yog: kev ua haujlwm siab kub, kev siv hluav taws xob ntau, tsis muaj peev xwm siv cov txheej ci, cov me me ntawm cov cwj pwm anode.
