Chithandizo cha Pamwamba pa Chitsulo - Njira Yotenthetsera Yoviikidwa ndi Galvanizing

Njira Yothira Magalasi Yotenthedwa Ndi Njira Yothira Zinc Pamwamba pa Chitsulo Kuti Ipewe Kutupa. Njirayi ndi yoyenera kwambiri pa zipangizo zachitsulo ndi chitsulo, chifukwa imawonjezera moyo wa chipangizocho ndikuwonjezera kukana kwake dzimbiri. Njira yonse yothira magalasi yotenthedwa ndi madzi imaphatikizapo izi:

1. Kukonza zinthu zisanakonzedwe: Chitsulocho chimayikidwa pamwamba pake, zomwe nthawi zambiri zimaphatikizapo kuyeretsa, kuchotsa mafuta, kutsuka ndi kugwiritsa ntchito madzi kuti zitsimikizire kuti pamwamba pa chitsulocho ndi poyera komanso popanda zinyalala.
2. Kuyika Zitsulo: Chitsulo chomwe chakonzedwa kale chimamizidwa mu madzi osungunuka a zinc omwe amatenthedwa kufika pa 435-530°C. Kenako chitsulocho chimamizidwa mu bafa yosungunuka ya zinc. Pa kutentha kwakukulu, pamwamba pa chitsulocho pamachitapo kanthu ndi zinc kuti apange gawo la zinc-iron alloy, njira yomwe zinc imasakanikirana ndi pamwamba pa chitsulo kuti ipange mgwirizano wa zitsulo.
3. Kuziziritsa: Chitsulo chikachotsedwa mu zinc solution, chimayenera kuziziritsidwa, zomwe zingatheke mwa kuziziritsa mwachilengedwe, kuziziritsa madzi kapena kuziziritsa mpweya.
4. Pambuyo pa chithandizo: Chitsulo choziziritsidwa cha galvanized chingafunike kuyang'aniridwa ndi kuchiritsidwa kwina, monga kuchotsa zinc yochulukirapo, kusinthasintha kuti chikhale cholimba, komanso kudzola mafuta kapena njira zina zochizira pamwamba kuti zipereke chitetezo chowonjezera.
Kapangidwe ka zinthu zopangidwa ndi ma galvanized otenthedwa ndi madzi ndi monga kukana dzimbiri bwino, kugwira ntchito bwino komanso kukongoletsa. Kukhalapo kwa zinc layer kumateteza chitsulo ku dzimbiri kudzera mu ntchito ya anode yoperekedwa nsembe, ngakhale zinc layer itawonongeka. Kuphatikiza apo, njira yopangira ma galvanization otenthedwa ndi madzi imaphatikizapo kupanga zinc-iron alloy phase layer mwa kusungunuka kwa chitsulo pansi pa nthaka ndi yankho la zinc, kufalikira kwina kwa zinc ions mu alloy layer mu substrate kuti apange zinc-iron intercalation layer, komanso kupanga zinc layer yoyera pamwamba pa alloy layer.

 

Kuyika ma galvanizing mu chidebe chotentha kumagwiritsidwa ntchito m'njira zosiyanasiyana, kuphatikizapo nyumba, mayendedwe, zitsulo ndi migodi, ulimi, magalimoto, zipangizo zapakhomo, zida zamakemikolo, kukonza mafuta, kufufuza za m'nyanja, zomangamanga zachitsulo, kutumiza mphamvu, kumanga zombo ndi madera ena. Mafotokozedwe wamba a zinthu zopangidwa ndi chidebe chotentha ndi monga muyezo wapadziko lonse wa ISO 1461-2009 ndi muyezo wa dziko lonse la China wa GB/T 13912-2002, womwe umatchula zofunikira pakukhuthala kwa chidebe chotentha, kukula kwa mbiri ndi mtundu wa pamwamba.
