Kodi waya wa mkuwa wopakidwa ndi siliva ndi chiyani?

Waya wopangidwa ndi siliva, womwe nthawi zina umatchedwa waya wopangidwa ndi siliva kapena waya wopangidwa ndi siliva, ndi waya woonda womwe umakokedwa ndi makina ojambula waya pambuyo poika siliva pa waya wopangidwa ndi mkuwa wopanda mpweya kapena waya wopangidwa ndi mkuwa wopanda mpweya. Uli ndi mphamvu zamagetsi, mphamvu zamagetsi, mphamvu zotsutsana ndi dzimbiri komanso mphamvu zotsutsana ndi kutentha kwambiri.
Waya wamkuwa wopangidwa ndi siliva umagwiritsidwa ntchito kwambiri pa zamagetsi, kulumikizana, ndege, usilikali ndi zina kuti achepetse kukana kwa pamwamba pa chitsulo ndikuwonjezera magwiridwe antchito owotcherera. Siliva ili ndi kukhazikika kwa mankhwala ambiri, imatha kupirira dzimbiri la alkali ndi ma organic acid ena, sigwirizana ndi mpweya mumlengalenga, ndipo siliva ndi wosavuta kupukuta ndipo ali ndi mphamvu yowunikira.

Kupaka siliva kungagawidwe m'mitundu iwiri: kupota kwa electroplating kwachikhalidwe ndi kupota kwa nanometer. Kupaka electroplating ndi kuyika chitsulo mu electrolyte ndikuyika ma ayoni achitsulo pamwamba pa chipangizocho ndi mphamvu kuti apange filimu yachitsulo. Kupaka nano ndikusungunula nano-material mu chemical solvent, kenako kudzera mu chemical reaction, nano-material imayikidwa pamwamba pa chipangizocho kuti ipange filimu ya nano-material.

Kuyika electroplating kuyenera choyamba kuyika chipangizocho mu electrolyte kuti chiyeretsedwe, kenako kudzera mu electrode polarity reversal, kusintha kwa kachulukidwe ka magetsi ndi njira zina kuti ziwongolere liwiro la polarization reaction, kuwongolera kuchuluka kwa malo ndi kufanana kwa filimu, ndipo pamapeto pake mu kutsuka, kuchotsa ma scaling, kupukuta waya ndi maulalo ena ogwiritsira ntchito pambuyo pokonza. Kumbali inayi, nano-plating ndi kugwiritsa ntchito mankhwala kuti asungunule nano-material mu chemical solvent mwa kuviika, kusakaniza kapena kupopera, kenako kuviika chipangizocho mu yankho kuti chiwongolere kuchuluka kwa yankho, nthawi yochitira ndi zina. Pangani nano-material kuphimba pamwamba pa chipangizocho, ndipo pamapeto pake chizimitsidwe kudzera mu maulalo ogwiritsira ntchito pambuyo pokonza monga kuumitsa ndi kuziziritsa.

Mtengo wa njira yopangira ma electroplating ndi wokwera kwambiri, zomwe zimafuna kugula zida, zipangizo zopangira ndi zida zokonzera, pomwe kupanga ma nanoplating kumangofunika zinthu zazing'ono ndi mankhwala osungunulira, ndipo mtengo wake ndi wotsika.
Filimu yopangidwa ndi ma electroplated ili ndi kufanana bwino, kumamatira, kunyezimira ndi zina, koma makulidwe a filimu yopangidwa ndi ma electroplated ndi ochepa, kotero zimakhala zovuta kupeza filimu yolimba kwambiri. Kumbali ina, filimu ya nano-material yokhala ndi makulidwe apamwamba ingapezeke pogwiritsa ntchito nanometer plating, ndipo kusinthasintha, kukana dzimbiri ndi kuyendetsa magetsi kwa filimuyo kumatha kulamulidwa.
Kupaka ma electroplating nthawi zambiri kumagwiritsidwa ntchito pokonza filimu yachitsulo, filimu ya alloy ndi filimu ya mankhwala, makamaka pokonza pamwamba pa zida zamagalimoto, zida zamagetsi ndi zinthu zina. Kupaka ma nanoplating kungagwiritsidwe ntchito pokonza pamwamba pa maze, kukonza zokutira zotsutsana ndi dzimbiri, zokutira zotsutsana ndi zala ndi zina.

Kupaka ndi kuyika nano-plating ndi njira ziwiri zosiyana zochizira pamwamba, kuyika ndi electroplating kuli ndi ubwino pa mtengo ndi kuchuluka kwa ntchito, pomwe kuyika nano-plating kumatha kukhala ndi makulidwe apamwamba, kusinthasintha bwino, kukana dzimbiri mwamphamvu komanso kuwongolera mwamphamvu, ndipo kuli ndi ntchito zosiyanasiyana.
