Hot-dip galvanizing, yomwe imadziwikanso kuti hot-dip galvanizing, imasungunula zinki yotentha-dip galvanizing ingot pa kutentha kwakukulu,

imayika zida zina zothandizira, kenako ndikumiza chigawo chachitsulo mu thanki yopangira galvanizing, kuti zinki wosanjikiza

zomangirizidwa ku chigawo chachitsulo.Ubwino wa kutentha-kuviika galvanizing ndi kuti odana ndi dzimbiri mphamvu ndi wamphamvu, ndi

zomatira ndi kuuma kwa kanasonkhezereka wosanjikiza bwino.Choyipa chake ndikuti mtengo wake ndi wokwera, zida zambiri

ndipo danga likufunika, kapangidwe kachitsulo ndi kokulirapo komanso kovutirapo kuyika mu thanki yopangira galvanizing, kapangidwe kazitsulo ndi

ofooka kwambiri, ndi kutentha-kuviika galvanizing ndi yosavuta kupunduka.Zovala zokhala ndi zinc nthawi zambiri zimatanthawuza zokutira zotsutsana ndi dzimbiri

okhala ndi zinc ufa.Zovala zokhala ndi zinc pamsika zimakhala ndi zinc imodzi.Ndikufuna kudziwa makulidwe a zinki

angagwiritse ntchito njira zotsatirazi

Maginito njira

Njira yamaginito ndi njira yoyesera yosawononga.Ikuchitika molingana ndi zofunikira za

GB/T 4956. Ndi njira yoyezera makulidwe a zinki wosanjikiza pogwiritsa ntchito electromagnetic makulidwe gauge.

Ndikoyenera kutchula apa kuti zida zotsika mtengo zingakhale, kulakwitsa kwakukulu kungayesedwe.Mtengo

zoyezera makulidwe zimachokera ku masauzande mpaka masauzande, ndipo tikulimbikitsidwa kugwiritsa ntchito zida zabwino zoyesera.

njira yoyezera

Malinga ndi zofunikira za GB/T13825, njira yoyezera ndi njira yolumikizirana.Kuchuluka kwa plating

zokutira zinki zoyezedwa ndi njirayi ziyenera kusinthidwa kukhala makulidwe a zokutira molingana ndi kachulukidwe

Kuphimba (7.2g / cm²).Njira iyi ndi njira yoyesera yowononga.Pankhani yomwe chiwerengero cha magawo ndi

zosakwana 10, wogula sayenera kuvomera monyinyirika ngati njira yoyezera

kuwonongeka kwa zigawozo ndi ndalama zowongola zomwe zimatsatira ndizosavomerezeka kwa wogula.

Anodic dissolution njira ya coulometric

Anode-kusungunula gawo lochepa la zokutira ndi njira yoyenera ya electrolyte, kusungunuka kwathunthu kwa

❖ kuyanika kumatsimikiziridwa ndi kusintha kwa magetsi a selo, ndipo makulidwe a ❖ kuyanika amawerengedwa kuchokera ku kuchuluka kwake

magetsi (mu coulombs) ogwiritsidwa ntchito ndi electrolysis, pogwiritsa ntchito nthawi kuti asungunuke zokutira ndi Mphamvu

kumwa, kuwerengera makulidwe a zokutira.

Ma microscopy amitundu yosiyanasiyana

Cross-sectional microscopy ndi njira yoyesera yowononga ndipo imangoyimira mfundo, kotero si kawirikawiri.

ntchito, ndipo ikuchitika molingana ndi GB/T 6462. Mfundo ndi kudula chitsanzo kuchokera workpiece kuti ayesedwe,

ndipo mutatha kuyikamo, gwiritsani ntchito njira zoyenera pogaya, kupukuta ndi kumangirira gawo lopingasa, ndikuyesa makulidwe ake.

wa mtanda gawo la chophimba wosanjikiza ndi wolamulira calibrated.
