Zinthu zopangidwa ndi zinc

Kodi mwawonapo chilichonse pamwamba pachitsulo chomwe chili chofiirira?Zimatchedwa dzimbiri, mdani woipitsitsa wa chitsulo, ndipo zimachokera ku momwe mamolekyu achitsulo achitsulo amachitira ndi chinyezi.Dzimbiri imayambitsa kuwonongeka kwa zinthu ndipo pamapeto pake imathandizira kulephera kwa zinthu ndi zida zamakina.Zinc platingamagwiritsidwa ntchito kuthana ndi vuto la kupanga dzimbiri popanga chotchinga chowonda pamwamba, kuti chisawonongeke pamene chikuchita ndi chilengedwe.

M'nkhaniyi, tidutsamontchito ya zinki plating, masitepe okhudzidwa, kukhudza zinthu ntchito, ubwino, ndi zofooka.

Kodi Zinc Plating ndi chiyani?

Njira imodzi yomalizitsira pamwamba pazinthu zachitsulo ndi zinthu zopangidwa ndi zinc plating.Kumaphatikizapo kuwonjezera wosanjikiza woonda pamwamba popanda kusokoneza kukhazikika kwa dimensional, kusiya malo osalala, otuwa.Zinc plating imapereka kukongola kokongola kwazinthu, koma kuposa pamenepo, kumapangitsa kuti zinthu zisawonongeke.Njira yopangira zinki imapanga zokutira zowonda zoteteza ndi electrodepositing zinc pazitsulo zomwe zidzakutidwe, zomwe zimatchedwanso gawo lapansi.

Kodi plating ya Zinc imagwira ntchito bwanji?

Zinc plating ikakumana ndi mpweya, imachita ndi okosijeni ngati zitsulo zachitsulo ndikupanga zinc oxide (ZnO), yomwe imaphatikizana ndi madzi kupanga zinc hydroxide (ZnoH).

Kupindika kumabwera tsopano pamene mpweya woipa wa carbon dioxide ndi zinc oxide umaphatikizana kupanga kagawo kakang'ono ka zinc carbonate (ZnCO3) komwe kumamatira ku zinki pansi ndikutetezanso kuti zisawonongeke.

Masitepe Ophatikizidwa ndi Zinc Plating

1.          Kuyeretsa pamwamba

Chinthu choyamba pakupanga zinki ndikuyeretsa pamwamba pake kuti apateke kuchotsa fumbi, mafuta, ndi dzimbiri kuti pamwamba pake apake ndi zinki bwino.Poyeretsa, zotsukira zamchere ndizothandiza kwambiri zomwe sizingawononge pamwamba.Komabe, kuyeretsa asidi kumatha kugwiritsidwa ntchito musanagwiritse ntchito zotsukira zamchere.

Kusamba pakati pa 100 ndi 180 digiri C kumathandiza kuchotsa grime musanagwiritse ntchito zotsukira zamchere poyeretsa ma microlevel.Mukatsuka ndi zotsukira zamchere, tsukani malowo nthawi yomweyo ndi madzi osungunuka kuti musawononge malo oyambira a zinthuzo, omwe njira za alkaline zimatha kuvulaza.Ngati kuyeretsa pamwamba sikunachitike bwino, Kutha kupangitsa kuti zokutira za Zinc kusweka kapena kuwonongeka.

2.          Kutola

Ma oxides ambiri, kuphatikiza dzimbiri lomwe lapanga kale, lingakhale pamwamba.Chifukwa chake, ndikofunikira kugwiritsa ntchito njira za asidi pochotsa ma oxide ndi masikelo musanayambe kuyika zinc.Njira ziwiri zomwe zimagwiritsidwa ntchito pochita izi ndi sulfuric ndi hydrochloric acid.Zogulitsa zimamizidwa mu njira ya asidi iyi.Nthawi yoviika, kutentha, ndi kuchuluka kwa asidi zimadalira mtundu wachitsulo ndi makulidwe a masikelo.

Kutsatira pickling ndi kuviika zigawo mu njira asidi, nthawi yomweyo yeretsani ndi madzi osungunuka kuti musachite chiwawa ndi kunyozetsa pamwamba.

3.          Kukonzekera plating kusamba

Chotsatira ndikukonzekera njira ya electrolytic ya electroplating process, yomwe imadziwikanso kuti plating bath.Kusamba ndi njira ya ayoni ya zinc yomwe imathandizira kuwongolera njira zopangira.Zitha kukhala zinc acid kapena zinki zamchere;

Asidi zinc: Kuchita bwino kwambiri, kuyika mwachangu, mphamvu yophimba bwino kwambiri, koma mphamvu yoponya yopanda mphamvu komanso kugawa kolimba kofooka.

Zinc ya alkaline:Kugawa kwa makulidwe abwino kwambiri ndi mphamvu zoponya zapamwamba, koma kusachita bwino kwambiri, kutsika kwa electrodeposition rate,

4.          Kukhazikitsa kwa Electrolysis & Kuyambitsa zamakono

Kupanga zinc-plating

Njira yeniyeni yoyikapo imayamba ndikuyambitsa magetsi (DC) mutasankha electrolyte kutengera zomwe mukufuna komanso zomwe mukufuna.Zinc imagwira ntchito ngati anode ndipo imaphatikizidwa kugawo loyipa la gawo lapansi (cathode).Zinc ions kugwirizana ndi cathode (Substrate) monga magetsi akuyenda mu electrolytes, kupanga woonda chotchinga wosanjikiza nthaka pamwamba.

Kuonjezera apo, pali njira ziwiri zopangira electrolysis: rack plating ndi mbiya plating (Rack & Barrel plating).

·   Racks:Gawo laling'ono limamizidwa mu electrolyte pomwe limamangiriridwa ku rack, Yoyenera magawo akulu

·   Mgolo:Gawo lapansi limayikidwa mu mbiya ndikuzungulira kuti likhale lopaka yunifolomu.

5.          Pambuyo pokonza

Kuti muchotse kuipitsidwa kulikonse komwe kungachitike pamwamba, mbali ziyenera kutsukidwa ndi madzi osungunuka kangapo plating ikatha.Pamaso kutumiza yokutidwa mankhwala kwa yosungirako pambuyo kutsuka, ayenera zouma.Ngati ndi kotheka, ma passivates ndi zosindikizira zitha kugwiritsidwanso ntchito kutengera miyezo yofunikira pakumaliza pamwamba.

Mfundo zofunika kuziganizira

Kudziwa chinthucho kumathandizira kuwongolera njirayo komanso kupeza zokutira koyenera.Zinthu zambiri zimakhudza zotsatira za plating pa gawo lapansi.

1.          Kachulukidwe kakali pano

Makulidwe a zinc wosanjikiza, omwe amafunikira kuyikidwa pamwamba pa gawo lapansi, amakhudzidwa ndi kachulukidwe kakudutsa komwe kumadutsa maelekitirodi.Chifukwa chake, Higher Current ipanga wosanjikiza wokulirapo pomwe yapansi panthaka ipanga wosanjikiza woonda.

2.          Kutentha kwa plating kusamba

Chinthu chinanso chomwe chimapangitsa kuti zinki plating ndi kutentha kwa njira ya electrolysis (Pating bath).Ngati kutentha ndi apamwamba cathode amadya ayoni wa haidrojeni ochepa ku yankho pamene pa nthawi yomweyo kutenga brighteners kwambiri kuti nthaka plating adzakhala owala chifukwa mafunsidwe apamwamba a zitsulo kristalo wa nthaka.

3.          Kuchuluka kwa zinc mu plating kusamba

Kuchuluka kwa zinki mu bafa yoyikira kumakhudzanso mawonekedwe a plating ndi kuchuluka kwa kuwala kwake.Mwachitsanzo, malo owoneka bwino amabwera chifukwa chokhala ndi zinc chifukwa ma ion a zinc amagawidwa mosiyanasiyana ndikusungidwa mwachangu.Kumbali inayi, kutsika kwapang'onopang'ono kumabweretsa kuwala kowala chifukwa makhiristo abwino amayikidwa pang'onopang'ono.

Zinthu zina zikuphatikizapomalo a Electrodes (anode & cathode), mawonekedwe apamwamba a gawo lapansi, Kukhazikika kwa ma surfactants ndi zowunikira pakusamba, kuipitsidwa., ndi zina.

Ubwino wake

Kuphatikiza pa kupewa dzimbiri, plating ya zinc ili ndi maubwino ena angapo;tiyeni tidutse ochepa ndi kufotokozera mwachidule.

·        Mtengo wotsika:Ndi njira yotsika mtengo yomalizitsa pamwamba poyerekeza ndi njira zina, kuphatikiza zokutira ufa, kumaliza kwa okusayidi wakuda, ndi plating yasiliva.

·        Limbitsani:Kupaka kwa zinki pazitsulo zachitsulo, mkuwa, mkuwa, ndi magawo ena kumathandiza kuonjezera mphamvu za zipangizozo.

·     Kukhazikika kwa Dimensional:Kuwonjezera zinc wosanjikiza sikungakhudze kukhazikika kwa magawo kapena zinthu,

·        Kukongola kokongola:Pambuyo plating, gawo lapansi lidzawoneka lonyezimira komanso lokopa, ndipo mitundu imatha kuwonjezeredwa pambuyo pokonza.

·        Ductility:Chifukwa zinki ndi chitsulo chopangidwa ndi ductile, kupanga gawo la pansi kumakhala kosavuta.

Asilikali:Matanki, zonyamula zida zankhondo, magalimoto, ndi zida zina zankhondo zimagwiritsa ntchito zinc plating.

Kuchepetsa kwa Zinc Plating

Zinc plating ndi njira yotsika mtengo komanso yoteteza zachilengedwe popewa dzimbiri pazinthu ndi zinthu zopangidwa ndi chitsulo, chitsulo, mkuwa, mkuwa, ndi zinthu zina zofananira.Komabe, ndizosayenera mafuta, mankhwala, zakuthambo, ndi zakudya, monga kumizidwa pafupipafupi muzothetsera.

Mapeto

Zinc plating ndi njira yovuta yomaliza yomwe imafunikira akatswiri akatswiri & ogwira ntchito okhala ndi zida zapamwamba zapamwamba.

takhala tikupereka ntchito zopangira pansi pa denga limodzi, kuchokera pamapangidwe a prototype mpaka kumaliza kwazinthu.Pogwiritsa ntchito ukadaulo wa Zinc plating, takhala tikupereka zapamwamba kwambiripamwamba kumalizantchito zamalonda ndi magawo kuchokera kwa akatswiri athu akatswiri omwe ali ndi zaka zambiri zamakampani.Chonde musazengereze kuteroLumikizanani nafengati mukufuna zina zowonjezera zokhudzana ndi plating ya Zinc.
