Umbane ofakwe igalvanized:
Intsimbi kulula ukugqwala emoyeni, emanzini okanye emhlabeni, okanye yonakaliswe ngokupheleleyo.Ilahleko yentsimbi yonyaka ngenxa ye-corrosion akhawunti malunga ne-1/10 yemveliso yensimbi yonke.Ukongezelela, ukwenzela ukuba unike umphezulu weemveliso zetsimbi kunye neengxenye umsebenzi okhethekileyo, ngelixa unika imbonakalo yokuhlobisa, ngokuqhelekileyo ziphathwa nge-electro-galvanizing.
① Umgaqo:
Ekubeni i-zinc ayilula ukuhluka emoyeni owomileyo, emoyeni omanzi, umphezulu unokuvelisa ifilimu ye-carbonate exineneyo kakhulu, enokukhusela ngokufanelekileyo ngaphakathi ukuba ingabikho i-corrosion.
② Iimpawu zokusebenza:
1. I-coating ye-zinc ingqindilili, ineekristale ezintle, ukufana kunye nokungabikho kwe-porosity, kunye nokumelana nokubola kakuhle;
2. I-zinc layer efunyenwe nge-electroplating ihlambulukile, kwaye i-corrodes ngokucothayo kwinkungu ye-asidi, i-alkali, njl., kwaye inokukhusela ngokufanelekileyo i-substrate yensimbi;
3. I-coating ye-zinc idluliswa yi-chromic acid ukwenza umhlophe, umbala, uhlaza lomkhosi, njl., elihle kwaye lihlobisa;
4. Ngenxa yokuba i-zinc i-coating ine-ductility enhle, inokuqulunqwa ngokubetha okubandayo, ukugoqa, ukugoba, njl njl ngaphandle kokulimaza ukugqoka.
③ Umda wesicelo:
Ngophuhliso lwemveliso yenzululwazi kunye nezobuchwepheshe, amasimi abandakanyekayo kwishishini le-electroplating aye abanzi ngakumbi.Okwangoku, ukusetyenziswa kwe-electro-galvanization kuye kwasasazeka kumasebe ahlukeneyo okuvelisa kunye nophando.
Kushushu iigalvanized:
Ⅰ.Isishwankathelo:
Kwindlela yokwaleka yeematrix zentsimbi ekhuselweyo, idiphu eshushu igqwesile kakhulu.Ikwimeko apho i-zinc ilulwelo, emva kwefiziksi entsonkothileyo, ikhemikhali, ingeyiyo kuphela umaleko we-zinc otyebileyo ongafakwanga kuphela kwintsimbi, kodwa kunye ne-zinc-ferrous layer.Le ndlela yokucoca ayinayo kuphela into yokumelana ne-corrosion ye-galvanization yombane, kodwa nangenxa ye-zinc iron alloy layer.Kananjalo inokumelana okuqinileyo ne-electroplated zinc.Ke ngoko, le ndlela yokucwenga ifaneleke ngokukodwa kwindawo eyomeleleyo edlayo efana neentlobo ngeentlobo zeasidi eyomeleleyo, inkungu yealkaline.
Ⅱ.Umgaqo:
I-Hot-dip galvanized layer yizinc kulwelo lobushushu obuphezulu, kwaye yenziwa ngamanyathelo amathathu:
1. I-iron-based surface ichithwa ngesisombululo se-zinc ukwenza isigaba se-zinc-ferrous;
2. I-Zinc ions kwi-alloy layer iphinda isasazwe kwi-substrate ukwenza i-zinc iron intercollation layer;
3. ubuso boluhlu lwe-alloy lufakwe kwi-zinc layer.
Ⅲ.Iimpawu zokusebenza:
(1) Inomaleko ashinyeneyo acwengekileyo wezinki kumphezulu wentsimbi, othintela ukudibana kwentsimbi ye matrix kuso nasiphi na isisombululo somhlwa ukukhusela imatrix yentsimbi ekudlekeni.Kwi-atmospheric jikelele, umphezulu we-zinc layer yenza uluhlu oluncinci kunye ne-intimate zinc oxide layer, okunzima ukunyibilika emanzini, ngoko ke i-matrix yensimbi idlala umphumo othile wokukhusela.
(2) Ngomaleko we-iron-zinc alloy, edityaniswe neshinyene, kwi-atmosphere yetyuwa ye-humex yolwandle kunye ne-industry atmosphere ibonise ukuxhathisa okukodwa kokuhlwa;
(3) Ekubeni udibaniso luqinile, i-zinc-iron i-solubilized, inokuxhathisa okuqinileyo;
(4) Ekubeni i-zinc ine-ductility enhle, i-alloy layer ifakwe ngokukhuselekileyo kwiqela lentsimbi, ngoko ke iindawo ezishushu ezitshisayo zinokubanda, zigoqwe, zixutywe, zigobe, kunye nokunye okunjalo ngaphandle kokonakalisa isambatho;
(5) Emva kwe-galvanization eshushu ye-finisse yensimbi, ilingana nonyango lwe-annealing, olunokuphucula ngokufanelekileyo iimpawu zomatshini we-matrix yensimbi, ukuphelisa uxinzelelo lwe-welding yensimbi yokubumba, enenzuzo yokuguqula ilungu lesakhiwo sensimbi.
(6) Umphezulu weziqwenga emva kwe-galvanization eshushu iqaqambile kwaye intle.

Ⅳ.Umda wesicelo:
Ukusetyenziswa kwe-hot-dip ghanely uphuhliso loshishino kunye nophuhliso lwezolimo.Ngoko ke, iimveliso ze-hot-dip ghared ziyi-industry (ezifana nezixhobo zekhemikhali, ukuqhutyelwa kweoli, ukuhlola iilwandle, isakhiwo sesinyithi, ukuhanjiswa kombane, ukwakhiwa kweenqanawa, njl.), ezolimo (ezifana nokufefa), izakhiwo (ezifana nokuhanjiswa kwamanzi kunye negesi, ucingo iseti Iityhubhu, isikafula, indlu, njl.), ibhulorho, ezothutho, njl. ziye zasetyenziswa kwiminyaka yakutshanje.
Kuba iimveliso ezishushu zediphu zinenkangeleko entle, ukusebenza kakuhle kokumelana nomhlwa, uluhlu lwesicelo lwayo luyanda.
