Ngokolwazi olugunyazisiweyo lwekhemikhali, i-zinc yintsimbi ekunzima ukuyidla. Xa i-zinc ifudumala phezu kwentsimbi, inokuthintela ukubola kunye nokugqwala xa ivele ibonakaliswe kumswakama kunye ne-oksijini emoyeni; ukongeza, i-zinc ikwaluhlobo lwentsimbi. Olu hlobo lwempahla lunokwandisa ukuguda, ezininziucingo lwensimbi ye-zincabavelisi basebenzisa le ndlela yokuthintela intsimbi ukuba ifakwe oxidized.
Insimbi ye-Zinc inokuthintela ukubola kwaye inikeze umaleko wefilimu ekhuselayo ye-zinc yesinyithi. Ukulungiswa kwezinto zetsimbi eziqhubayo kunye ne-agent yokunyamekela ngokunyuka kombala; ukhuseleko oluphindwe kabini olukhuselekileyo noluthembekileyo, i-synthetic metal resin layer protective layer and cathodic protective layer, inokumelana nemozulu embi, Ifanelekile ukukhuselwa kwexesha elide lesinyithi; ukuxhathisa okugqwesileyo kwi-corrosion yityuwa kunye namanzi. Ukunamathela okuqinileyo kuzo zonke iintlobo zesinyithi kunye ne-alloys yazo, inokutshizwa ngokuthe ngqo ngaphandle kwe-primer, ukumelana nobushushu obuphezulu, ungoyiki ukubhaka, emva kokumisa, i-coating inokumelana nokushisa okuphezulu malunga ne-120 ℃. Ubushushu bokuchasana nokomisa bunokufikelela kwi-80℃, kwaye yoma ngokukhawuleza. I-Economic and practical, inokuthintela umhlwa ngesitshizi esinye.
Umsebenzi wokuchasana nomhlwa weucingo lwensimbi ye-zincayisekelwe kuphela kumxholo we-zinc kwi-coating ye-zinc, kodwa iphinda ichaphazeleke ngobukhulu bamaqhekeza kwi-zinc layer. Incinci i-zinc particles, i-high density ye-coating, kwaye umgangatho ophezulu we-coating ufana ne-100% yobushushu obuphezulu be-hot-dip coating. Umsebenzi wala masuntswana amahle kukwenza i-coating iqina, ayithinteli kuphela ukubola, kodwa inokuba yityatyambo elingaphantsi okanye elilingana ne-120μm (umphezulu othe nkqo) ukukhusela ukuguquguquka kwamacandelo e-zinc. Ngaphantsi kweemeko eziqhelekileyo zokusetyenziswa, ixesha lokuchasana ne-corrosion kwi-atmosfera linokufikelela kwiminyaka engaphezu kwama-30.
