Umhlwa weMbhobho yentsimbi eGalvanized

Umbhobho wentsimbi owenziwe ngamachiza umhlwa ikakhulu yenzelwe i-zinc enyibilikayo kwiasidi kwaye kwakhona inyibilika kwi-alkali, yibize ngokuba yintsimbi yesini.I-Zinc emoyeni owomileyo phantse akukho tshintsho.Kumoya omanzi, indawo ye-zinc iya kuvelisa ifilimu eshinyeneyo ye-zinc carbonate esisiseko.Iqulethe i-sulfur dioxide, i-hydrogen sulfide kunye ne-atmosfera yaselwandle, ukuxhathisa okungahambi kakuhle kwe-zinc, ngakumbi kwi-atmospheric eshushu nefumileyo equlethe i-organic acids, i-zinc yokwaleka ngokulula inokuhlwa.I-zinc standard electrode enokubakho-0.76V, i-substrate yentsimbi, i-zinc yokwambathisa i-anodic coating, esetyenziselwa ukuthintela ukubola kwentsimbi kunye nentsimbi, iinzuzo kunye neengozi zeempawu zayo ezikhuselayo zobudlelwane bobunzima obukhulu.

I-Zinc yokugqoka, i-passivation, i-staining okanye i-coating egcina i-arhente yokukhanya, inokuphucula kakhulu ukukhusela kunye nokuhlobisa.I-zinc oxide emoyeni, umphezulu wokubunjwa kwe-rust emhlophe, le meko iqhelekile.Kuxhomekeke umcu wakho idiphu eshushu galvanized okanye i-electro-galvanized, dip eshushu ifakwe igalvanized, ke ngenxa yokuba umaleko otyebileyo we-zinc ukuvelisa umhlwa omhlophe awuchaphazeli iwaranti eqhelekileyo, kuba izinga le-oxidation ye-zinc emoyeni licotha kakhulu.I-Electro-galvanized ayilula ukuyithetha.Ukungaboni umhlwa akuyi kuchaphazeleka.Xa ufuna ukugcina isinyithi esinezibilini ukuba uqaphele ukuba ungafaki umoya omanzi kunye nobushushu bemozulu kulula kakhulu ukubumba, ezinye zasebusika, uze ubambelele kwixesha elide.

Iimfuno zobugcisa zemibhobho yentsimbi yesinyithi

Kwinkqubo yokuhlolwa komgangatho wombhobho wediphu yentsimbi eshushu, eyona ngongoma iphambili kukusebenza kwesicelo sombhobho wentsimbi.
Indawo yokugoba yediphu eshushu eyenziwe ngamazi ibhekisa kwisenzeko semathiriyeli yesinyithi enesivuno, inqanaba lokugoba lomfanekiso kwintsimbi ekhandisiweyo ekuqaleni ekubumbeni kubaluleke kakhulu, kuba inokuvavanya umbhobho wentsimbi ngoxinzelelo lwangaphandle xa isabela. , ukuba uvavanyo lwatshiselwa umbhobho wentsimbi kwindawo ebaluleke kakhulu, sinokuba nokuqiniswa okufanelekileyo kombhobho wentsimbi ukufikeleleka ngakumbi ngokweemfuno zabathengi.
Ukuba ukwehla kwamandla kuyenzeka, kufuneka kwahlulwe phakathi kweqondo lesivuno esingaphezulu nesisezantsi.Inqaku eliphezulu lesivuno lisampulu yokuvelisa amandla awela okokuqala ngaphambi kokuba uxinzelelo olukhulu lwenzeka;isivuno esisezantsi inqanaba loxinzelelo oluncinci xa ungabandakanyi umphumo wokuqala wexeshana, isigaba sesivuno.Isalathiso sezinto ezilukhuni zetsimbi ukuxhathisa izinto ezilukhuni ukunyathela isakhono somphezulu, owaziwa ngokuba lukhuni.
Ngokuxhomekeke kwiindlela zovavanyo kunye nobubanzi bobulukhuni bunokwahlulwa ibe bubunzima beBrinell, ukuqina kweRockwell, ubulukhuni beVickers, ukuqina konxweme, ubulukhuni obuncinci kunye nobunzima obuphezulu bobushushu.Ngokuqhelekileyo isetyenziselwa umbhobho Brinell, Rockwell, Vickers ubulukhuni.
