Hot dip galvanizing, yomwe imadziwikanso kuti galvanizing, ndi njira yomiza zigawo zachitsulo mu zinki zosungunula kuti mupeze zitsulo zopangira zitsulo. Electro galvanizing imadziwika kuti "cold galvanizing" kapena "water galvanizing";amagwiritsa ntchito electrochemistry, pogwiritsa ntchito zinc ingot ngati anode.Ma atomu a zinki amataya ma elekitironi awo ndikukhala ayoni ndikusungunula mu electrolyte, pomwe zinthu zachitsulo zimagwira ntchito ngati anode.Pa cathode, ayoni a zinki amalandira ma electron kuchokera ku chitsulo ndipo amachepetsedwa kukhala maatomu a zinki omwe amaikidwa pamwamba pa chitsulo kuti akwaniritse njira yomwe zokutira zimapanga yunifolomu, wandiweyani, komanso womangika bwino zitsulo kapena aloyi deposition layer. Nkhaniyi ifotokoza mozama za kusiyana kwa zinthu ziwirizi.
1. Kupaka makulidwe osiyanasiyana
Chophimba chotenthetsera chamalata nthawi zambiri chimakhala ndi zinc wokhuthala, pafupifupi 40 μm kapena kupitilira apo, kapena mpaka 200 μm kapena kupitilira apo.Wosanjikiza wotentha wa dip amakhala nthawi 10 mpaka 20 kuposa wa electroplated zinki wosanjikiza.Electroplated zinki zokutira ndi woonda kwambiri, pafupifupi 3-15μm, ndi ❖ kuyanika kulemera ndi 10-50g/m2 okha.
2. Mitundu yosiyanasiyana ya galvanizing
Kuchuluka kwa galvanizing zitsulo zoviikidwa pazitsulo zoviikidwa sizingakhale zochepa kwambiri.Nthawi zambiri, chocheperako ndi 50 ~ 60g/m2 mbali zonse ndipo chachikulu ndi 600g/m2.The kanasonkhezereka wosanjikiza electro kanasonkhezereka zitsulo koyilo akhoza kukhala woonda kwambiri, ndi osachepera 15g/m2.Komabe, ngati ❖ kuyanika kuyenera kukhala kokulirapo, liwiro la mzere wopangira lidzakhala wodekha kwambiri, lomwe silili loyenera machitidwe a mayunitsi amakono.Nthawi zambiri, kuchuluka kwake ndi 100g/m2.Chifukwa cha izi, kupanga ma electro galvanized steel sheets ndikoletsedwa kwambiri.
3. Mapangidwe ophimba ndi osiyana
Pali chosanjikiza pang'ono pakati pa zokutira zoyera za zinki za pepala lothira lamalata ndi mbale yachitsulo.Pamene zokutira koyera zinki zimawonekera, maluwa ambiri a zinki amapangidwa, ndipo chophimbacho chimakhala chofanana ndipo alibe pores.The maatomu zinki mu electroplated zinki wosanjikiza ndi mpweya kokha pamwamba pa mbale zitsulo, ndipo thupi Ufumuyo pamwamba pa zitsulo Mzere.Pali ma pores ambiri, omwe angayambitse dzimbiri mosavuta chifukwa cha zowononga media.Choncho, otentha kuviika kanasonkhezereka mbale ndi kugonjetsedwa ndi electro kanasonkhezereka mbale dzimbiri.
4. Njira zosiyanasiyana zochizira kutentha
Zitsulo zoviikidwa zoviikidwa pa malata nthawi zambiri zimapangidwa ndi mbale zoziziritsa zolimba ndipo zimapitirizidwa mosalekeza ndi kuthirira kotentha kumakometsedwa pamzere wokokera.Mzere wachitsulo umatenthedwa kwa kanthawi kochepa kenaka utakhazikika, kotero mphamvu ndi pulasitiki zimakhudzidwa pamlingo wina.Magwiridwe ake a stamping ndi abwino kuposa Chimbale cholimba chozizira chomwecho ndi chosiyana ndi mbale yachitsulo yozizira pambuyo pochotsa mafuta ndikuyimitsa pamzere wopanga akatswiri.Hot choviikidwa kanasonkhezereka zitsulo ndi mtengo wotsika kupanga ndi lonse ntchito osiyanasiyana, ndipo akhala zosiyanasiyana waukulu mu kanasonkhezereka pepala msika.Electro kanasonkhezereka zitsulo mapepala ntchito ozizira adagulung'undisa zitsulo mapepala ngati zipangizo, amene kwenikweni zimatsimikizira ntchito yomweyo processing wa mapepala ozizira adagulung'undisa, koma ndondomeko yake yovuta kumawonjezera mtengo kupanga.
5. Maonekedwe osiyana
Pamwamba pa kutentha kuviika kanasonkhezereka wosanjikiza ndi akhakula ndi owala, ndipo kwambiri milandu pali nthaka maluwa;electro galvanized layer ndi yosalala komanso imvi (yothimbirira).
6. Kusiyanasiyana kwa ntchito ndi njira
Kutentha-kuviika galvanizing ndi oyenera zigawo zikuluzikulu ndi zipangizo;otentha-kuviika galvanizing ndi pickle zitsulo chitoliro choyamba.Pofuna kuchotsa chitsulo okusayidi pamwamba pa chitsulo chitoliro, pambuyo pickling, izo anadutsa ammonium kolorayidi kapena zinki kolorayidi amadzimadzi njira kapena ammonium kolorayidi ndi klorini.Zinki wosanganiza amadzimadzi njira thanki kuyeretsa, ndiyeno anatumiza otentha kuviika plating thanki.
Chitsulo choviikidwa choviikidwa bwino chimakhala ndi chophimba chabwino, zokutira wandiweyani, ndipo palibe zophatikizika.Ili ndi ubwino wa zokutira yunifolomu, kumamatira mwamphamvu komanso moyo wautali wautumiki.Dip galvanizing yotentha imalimbana bwino ndi dzimbiri mumlengalenga wa chitsulo choyambira kuposa galvanizing yamagetsi.
Mapepala achitsulo opangidwa ndi electroplating ali ndi ntchito yabwino yopangira, koma zokutira ndi zoonda ndipo kukana kwa dzimbiri sikuli bwino ngati mapepala achitsulo oviikidwa;kuchuluka kwa zinki kumangirizidwa ku electro galvanized steel coilis kakang'ono kwambiri, ndipo khoma la chitoliro lakunja lokha ndilokhala ndi malata, pomwe kuthirira kotentha kumakhala mkati ndi kunja.
