Iimveliso ze-zinc zinobuhlobo nokusingqongileyo kwaye kulula ukuzisebenzisa kwakhona ngenxa yokunganyangeki kwe-corrosion, ukusetyenzwa lula, ukubumba okucebileyo, ukuhambelana okuqinileyo nezinye izinto. Ngobuhle obuhle kunye nokuqina, i-zinc ithandwa ngokubanzi kuyilo lophahla oluphezulu lwentsimbi kunye neenkqubo zodonga namhlanje.
Isitya seZincngokuqhelekileyo esetyenziswa kulwakhiwo yimathiriyeli yesinyithi yanamhlanje eneempawu ezibalaseleyo ezenziwe ngokudibanisa inani elincinci kakhulu le-titanium (0.06% ~ 0.20%), i-aluminiyam kunye ne-alloy element yobhedu kunye ne-zinc njengenxalenye ephambili, eyaziwa ngokuba yi-titanium-zinc plate. I-zinc ebizwa ngokuba yi-"titanium zinc" yenziwe nge-high-grade electrolytic zinc kunye nokucoceka ukuya kwi-99.99% kwaye inyibilika ngobhedu oluchanekileyo kunye nobuninzi kunye ne-titanium, ephucula ukusebenza kokucubungula kunye neempawu zemishini ye-zinc, kunye nomgangatho ungcono.
Emva kokongeza ubhedu kunye ne-titanium kwi-zinc, iimpawu ze-zinc plate ziba phezulu. I-Copper iphucula kakhulu amandla okuqina e-alloy, kwaye i-titanium iphucula ukuxhathisa kwe-alloy plate ngokuhamba kwexesha. I-alloy yezinyithi ezine yenza ipleyiti i-coefficient yokwandisa iyancitshiswa.
Xa i-zinc sheet idibana ne-carbon dioxide kunye namanzi emoyeni, kukho izigaba ezibini eziphambili kwinkqubo yokutshintsha kwemichiza, oko kukuthi ukubunjwa kwe-zinc hydroxide carbonate layer kunye ne-zinc carbonate layer. Olu luhlu lwe-oxide oluxineneyo lusebenza njengefilimu ekhuselayo yokukhusela i-zinc yangaphakathi kwi-corrosion eqhubekayo, iqinisekisa ubomi benkonzo yexesha elide le-sheet metal.
Ekwakhiweni, i-zinc sheet ineenzuzo ezibonakalayo xa kuthelekiswa neshiti lentsimbi esetyenziswa ngokuqhelekileyo kunye ne-aluminium sheet. Iphepha le-Zinc linezinto zokuzikhusela, kwaye akukho nolunye unyango olukhethekileyo oluchasene ne-corrosion olufunekayo. Nokuba umphezulu wonakaliswe, umaleko okhuselayo unokuphinda uqulunqwe kunye neempawu zayo zokuzikhusela ukuze uthintele ukubola. Iphepha le-galvanized kunye ne-aluminium sheet liya kukrazula okanye likhuphe umaleko we-zinc okanye ifilimu ye-oxide phezu komhlaba ngenxa ye-bumping kunye nezinye izizathu, kwaye emva koko i-corrode, ngoko iindleko ezongezelelweyo zokulondoloza ziyafuneka.
