Kusiyana pakati pa electro-galvanizing ndi hot-dip galvanizing

Pamwamba pazitsulo nthawi zambiri zimakhala ndi galvanized layer, zomwe zingalepheretse zitsulo kuti zisachite dzimbiri pamlingo wina.Chitsulo cha galvanized chimapangidwa ndi galvanizing yotentha kapena electro-galvanizing.Ndiye pali kusiyana kotanikutentha-kuviika galvanizingndi electro-galvanizing?

Electro Galvanizing Process

Electrogalvanizing, wotchedwanso ozizira galvanizing mu makampani, ndi ndondomeko ntchito electrolysis kupanga yunifolomu, wandiweyani ndi bwino Bonded zitsulo kapena aloyi mafunsidwe wosanjikiza pamwamba pa workpiece.

Poyerekeza ndi zitsulo zina, zinki ndi chitsulo chotsika mtengo komanso chokutidwa mosavuta.Ndizitsulo zotsika mtengo zotsutsana ndi dzimbiri ndipo zimagwiritsidwa ntchito kwambiri kuteteza mbali zachitsulo, makamaka kuti zisawonongeke mumlengalenga, komanso zokongoletsera.Njira zopangira plating zimaphatikizapo plating (kapena rack plating), plating mbiya (zigawo zing'onozing'ono), plating buluu, plating basi ndi mosalekeza plating (waya, mizere).

Mawonekedwe a electro-galvanized

Cholinga cha electrogalvanizing ndi kuteteza zinthu zitsulo kuti zisawonongeke, kupititsa patsogolo kukana kwa dzimbiri ndi moyo wautumiki wachitsulo, ndipo nthawi yomweyo kuwonjezera maonekedwe okongoletsera a mankhwala.Chitsulo chidzawonongeka, madzi kapena nthaka idzawonongeka pakapita nthawi.Chitsulo chomwe chimawonongeka chaka chilichonse ku China chimapanga pafupifupi gawo limodzi mwa magawo khumi a zitsulo zonse.Choncho, pofuna kuteteza moyo wautumiki wachitsulo kapena mbali zake, electro-galvanizing amagwiritsidwa ntchito pokonza zitsulo.

Popeza nthaka sikophweka kusintha mu mpweya wouma, ndipo akhoza kupanga maziko zinki carbonate filimu mu chikhalidwe chinyezi, filimuyi akhoza kuteteza mbali zamkati kuwonongeka dzimbiri, ngakhale nthaka wosanjikiza kuonongeka ndi chinthu.Nthawi zina, zinki ndi zitsulo zimaphatikizana pakapita nthawi kuti zipange microbattery, ndi matrix achitsulo otetezedwa ngati cathode.Chidule cha Electrogalvanizing chili ndi izi:

1. Kukaniza bwino kwa dzimbiri, kuphatikiza mosamala komanso yunifolomu, sikophweka kulowetsedwa ndi mpweya wowononga kapena madzi.

2. Chifukwa chosanjikiza cha zinc ndi choyera, sikophweka kuti chiwonongeke mu acid kapena alkali chilengedwe.Mogwira kuteteza thupi zitsulo kwa nthawi yaitali.

3. Pambuyo pa passivation ndi chromic acid, ikhoza kugwiritsidwa ntchito mumitundu yosiyanasiyana, yomwe ingasankhidwe malinga ndi zomwe makasitomala amakonda.The galvanizing ndi zokongola ndi kukongoletsa.

4. Chophimba cha zinki chimakhala ndi ductility chabwino ndipo sichidzagwa mosavuta panthawi yopindika, kugwiritsira ntchito komanso kukhudzidwa.

Kodi pali kusiyana kotani pakati pa hot-dip galvanizing ndi electro-galvanizing?

Mfundo za awiriwa ndi zosiyana.Electrogalvanizing ndi kumangitsa kanasonkhezereka wosanjikiza pamwamba pa chitsulo ndi electrochemical njira.Kutentha-kuviika galvanizingndi kumiza zitsulo mu njira ya zinki kupanga pamwamba pa zitsulo ndi malata wosanjikiza.

Pali kusiyana kwa maonekedwe pakati pa awiriwa.Ngati chitsulocho ndi electro-galvanized, pamwamba pake ndi bwino.Ngati chitsulo chatentha-kuviika kanasonkhezereka, pamwamba pake ndi akhakula.Zovala zamagalasi amagetsi nthawi zambiri zimakhala 5 mpaka 30μm, ndi zokutira otentha-kuviika malata zambiri 30 mpaka 60μm.

Kuchuluka kwa ntchito ndi kosiyana, kuthirira kotentha kumagwiritsidwa ntchito kwambiri muzitsulo zakunja monga mipanda yamisewu yayikulu, ndipo electro-galvanizing imagwiritsidwa ntchito kwambiri muzitsulo zamkati monga mapanelo.
