Electro galvanizing
Kufotokozera Kwachidule:
Electro galvanizing: amatchedwanso ozizira galvanizing mu makampani, ndi ndondomeko kupanga yunifolomu, wandiweyani ndi bwino Bonded zitsulo kapena aloyi mafunsidwe wosanjikiza pamwamba pa workpiece ndi electrolysis.
Poyerekeza ndi zitsulo zina, zinki ndi zotsika mtengo komanso zosavuta kuzikuta.Ndi mtengo wotsika anti-corrosion electroplated zokutira.Amagwiritsidwa ntchito kwambiri kuteteza mbali zachitsulo ndi zitsulo, makamaka pofuna kupewa kuwonongeka kwa mlengalenga, komanso kukongoletsa.Ukadaulo wa plating umaphatikizanso kubisala (kapena kupachika), kuyika migolo (yoyenera tizigawo ting'onoting'ono), plating ya buluu, plating yokha ndi plating mosalekeza (yoyenera waya ndi mizere).

Cholinga cha electro galvanizing ndi kuteteza zinthu zitsulo kuti zisawonongeke, kupititsa patsogolo kukana kwa dzimbiri ndi moyo wautumiki wachitsulo, ndikuwonjezera maonekedwe okongoletsera a zinthu.Chitsulo chidzaipitsidwa ndi nyengo, madzi kapena nthaka ndikuwonjezeka kwa nthawi.Ku China, zitsulo zowonongeka zimakhala pafupifupi gawo limodzi mwa magawo khumi a zitsulo zonse chaka chilichonse.Choncho, pofuna kuteteza moyo wautumiki wachitsulo kapena mbali zake, electro galvanizing amagwiritsidwa ntchito pokonza zitsulo.
Chifukwa nthaka sizovuta kusintha mu mpweya wouma ndipo imatha kupanga filimu ya zinki carbonate m'malo achinyezi, filimuyi imatha kuteteza ziwalo zamkati kuti zisawonongeke.Ngakhale zinki wosanjikiza kuonongeka ndi zinthu zina, nthaka ndi zitsulo adzaphatikizana kupanga yaying'ono batire pakapita nthawi, kuti masanjidwewo zitsulo kukhala cathode ndi kutetezedwa.Zimaganiziridwa kuti electro galvanizing ali ndi makhalidwe awa:
Ili ndi kukana kwa dzimbiri bwino, kuphatikiza bwino komanso kofanana, ndipo sikophweka kulowetsedwa ndi mpweya wowononga kapena madzi.
Chifukwa chosanjikiza cha zinc ndi choyera, sikophweka kuti chiwonongeke mu acid kapena alkali chilengedwe.Mogwira kuteteza thupi zitsulo kwa nthawi yaitali.
Itha kugwiritsidwa ntchito mumitundu yosiyanasiyana pambuyo pa chromate passivation.Ikhoza kusankhidwa malinga ndi zomwe makasitomala amakonda.Galvanizing ndi yokongola komanso yokongoletsa.
Chophimba cha zinki chimakhala ndi ductility yabwino ndipo sichingagwe mosavuta panthawi yopindika, kugwira ndi kukhudzidwa.
