Tin plating txheej txheem rau hexagonal bolts

Tin yog ib qho nyiaj dawb hlau uas tsis muaj tshuaj lom thiab muaj qhov zoo weldability thiab ductility. Siv dav hauv kev lag luam xws li hluav taws xob, khoom noj khoom haus, thiab tsheb. Cov txheej txheem tin plating rau hexagonal bolts yog cais raws li tus nqi pH ntawm cov tshuaj plating, thiab muab faib ua ob pawg: cov txheej txheem acidic plating thiab alkaline tin plating txheej txheem.
Qhov zoo ntawm acidic tin plating yog ceev plating ceev. Cov txheej yog ci thiab zoo tib yam, nrog zoo sib sib zog nqus plating muaj peev xwm. Cov tshuaj plating muaj qhov ua siab ntev rau impurities thiab txuag lub zog thaum ua haujlwm kub hauv chav. Qhov tsis zoo ntawm Mina yog qhov muaj peev xwm dispersion ntawm cov tshuaj plating tsis zoo, thiab cov porosity ntawm txheej yog siab. Brazing tsis zoo li alkaline tin plating, thiab divalent tin yog hydrolyzed. Acid tin plating ntawm hexagonal bolts tuaj yeem muab faib ua cov txheej txheem xws li sulfate tin plating, fluoroborate tin plating, chloride tin plating, thiab lwm yam vim muaj cov khoom sib txawv.
Sulfuric acid tin plating muaj tus nqi qis, yooj yim los tswj cov tshuaj plating, ci thiab zoo txheej, tab sis tsis muaj peev xwm dispersion. Kev ua lag luam feem ntau yog siv. Qhov zoo ntawm fluoroborate tin plating yog ceev plating ceev, siab siv tam sim no, thiab zoo da dej stability. Dav siv rau kev nruam electroplating ntawm flange ceev, xov hlau, thiab strips. Qhov tsis zoo yog tus nqi siab ntawm cov tshuaj plating, siab toxicity, thiab nyuaj rau kev kho dej khib nyiab.
Chloride tin plating feem ntau yog siv rau hauv cov khoom siv lead ua tin plating, nrog rau qhov zoo ntawm tus nqi qis, ruaj khov plating tov, thiab ntxuav dawb txheej. Qhov tsis zoo yog qhov tam sim no tsis siab heev. Qhov zoo ntawm alkaline tin plating ntawm hexagonal bolts yog: yooj yim muaj pes tsawg leeg, zoo dispersion muaj peev xwm ntawm cov tshuaj plating, nplua txheej, ob peb pores, thiab zoo brazing kev ua tau zoo. Qhov tsis zoo yog: kev khiav hauj lwm kub, siab zog noj, nqaim ntau yam ntawm kev siv tam sim no, tsis tshua muaj kev ua haujlwm tam sim no, tsis muaj peev xwm kom tau txais cov txheej ci ci, txheej txheej me me, thiab cuam tshuam rau tus cwj pwm anode.
