Common mavuto galvanizing ndondomeko lalikulu mpukutu kanasonkhezereka waya

Amapaka waya ❖ kuyanika akhakula, passivation filimu si kowala, kusamba kutentha kwambiri.Ngati kachulukidwe ka cathode panopa ndi wochuluka kwambiri, zinki zomwe zili mu bafa ndizokwera kwambiri kapena sodium hydroxide ndi DPE ndizochepa kwambiri;Electroplating solution yokhala ndi tinthu tating'onoting'ono kapena zonyansa zakunja zakunja, zitha kuyambitsa mavuto.Yankho: Ngati mpukutu waukulu kanasonkhezereka waya pamwamba ❖ kuyanika ndi akhakula, pangakhale olimba particles mu plating njira.Ngati kuuma kwa gawolo kuli koopsa, kachulukidwe kameneka kangakhale kokwera kwambiri.

Ngati kuyanika kwa zinki kuli bwino, koma kuwala kumatuluka mu 3% nitric acid, pamakhala mthunzi wakuda pa zokutira, ndipo filimuyo imakhala yofiirira pamene passivation imachitika, zomwe zingayambitsidwe ndi zonyansa zakunja zachitsulo monga mkuwa kapena kutsogolera. m'madzi opangira malata.Pamene pali vuto m`kati galvanizing, fufuzani kutentha ndi kachulukidwe panopa, ndiyeno kuyeza ndi kusintha zili nthaka ndi sodium hydroxide mu kusamba mwa kusanthula kusamba.Kaya milingo ya DPE ndiyotsika imatha kudziwika ndi kuyesa kwa cell ya Hull.

Ngati kuyanika roughness si chifukwa cha zifukwa pamwamba, zikhoza chifukwa cha zosafunika mu plating njira.Angathe kutenga pang'ono njira electroplating, pambuyo kusefera mayeso, ndiye kutenga pang'ono ya electroplating njira, pambuyo nthaka kuyezetsa ufa mankhwala, fufuzani vuto amayamba ndi particles olimba kapena mkuwa, kutsogolera ndi zina zachilendo zitsulo zosafunika.Ayeseni mmodzimmodzi ndipo sizovuta kupeza chomwe chayambitsa vutoli.Kanasonkhezereka chitsulo waya ❖ kuyanika thovu, kumanga mphamvu si zabwino.

Osauka pretreatment pamaso electroplating;Kutentha kwa kusamba ndi kochepa kwambiri;Zowonjezera zabwino kapena zowonjezera kwambiri ndi zonyansa za organic zingayambitse kusamvana.Ubwino wa zowonjezera zimakhalanso ndi zotsatira za kupaka thovu.Zowonjezera zina zimachita mosakwanira panthawi ya kaphatikizidwe ndikupitiriza kupangika posungira nthawi yayitali kapena kugwiritsidwa ntchito.Chowonjezeracho chimakonda kupotoza lattice ndikupanga kupsinjika, kuchititsa kuti zokutira ziwonongeke.

Pamene lalikulu mpukutu kanasonkhezereka waya galvanizing ndondomeko ❖ kuyanika thovu, choyamba fufuzani kusamba kutentha.Ngati kusamba kutentha si otsika, ndiye kulimbikitsa plating pamaso kuchotsa mafuta, kuteteza masanjidwewo zitsulo mu asidi dzimbiri.Ngati inu kulabadira mavuto amenewa, thovu chodabwitsa akadalipo, ayenera kulabadira kuchuluka ndi khalidwe zina, ndiye inu mukhoza kusiya kuwonjezera zina, ndi mkulu panopa electrolysis kwa nthawi, kuti kuchepetsa zili zowonjezera, onani ngati chodabwitsa cha thovu chikuyenda bwino.Ngati palibe kusintha, ndikofunikira kuyang'ana ngati nthawi yosungiramo zowonjezera ndi yayitali kwambiri, kapena ngati pali zonyansa zambiri pazowonjezera.
