Ehlabathini lokwakhiwa kunye nokusetyenziswa kwezoshishino, isinyithi esinamanzi sithathwa ngokubanzi njengenye yezinto ezihlala zihlala zihlala zihlala zihlala zihlala zihlala zihlala zihlala zihlala zihlala zihlala zihlala zihlala zihlala zihlala zihlala zihlala zihlala zihlala zihlala zihlala zihlala zihlala zihlala khona. Ukuxhatshazwa kwayo kwe-corrosion sizathu esibalulekileyo sokuthandwa kwayo, ngakumbi kwiindawo apho isinyithi sibonakaliswe kwiimeko zemozulu ezinzima. Shandong Sino Steel Co., Ltd., umenzi ohamba phambili weentsimbi zentsimbi kunye ensimbi amashiti , uvelisa iimveliso ezikumgangatho ophezulu ezingathembekanga kuphela kodwa zikhangeleka. Eli nqaku liza kuphonononga ubume bokwenyani bokumelana nomhlwa kwentsimbi, ukuba isebenza njani, kwaye kutheni ilukhetho olubalaseleyo kumashishini ahlukeneyo, ukusuka kulwakhiwo ukuya kwimveliso.
Yintoni ngokwenene 'Ubungqina bomhlwa' kwiNsimbi?
Xa sibhekisela kwintsimbi yokukhusela i-rust-proof, sihlala sicinga ngentsimbi engayi kutshabalalisa okanye igxume, kungakhathaliseki ukuba iimeko zinjani. Nangona kunjalo, 'i-rust-proof' ligama elithile elahlekisayo. Ngelixa intsimbi ekhandisiweyo inika ukhuseleko olubalaseleyo kumhlwa, ayikhuselekanga ngokupheleleyo ekudlekeni. Ukuqonda umahluko phakathi 'kwe-corrosion' kunye 'nerust' kubalulekile ekuvavanyeni ukusebenza kwentsimbi.
Umhlwa vs. Umhlwa – Umahluko
Ukonakala kubhekiselele ekuwohlokeni kancinci kancinci kwesinyithi ngenxa yokusabela kweekhemikhali kunye nokusingqongileyo. Umhlwa, kwelinye icala, ubhekisela ngokukhethekileyo kwinto enamatheku bubomvu-bumdaka ebakho xa i-iron neoksijini zisabela xa kukho amanzi. Ayizizo zonke i-corrosion eziphumela kumhlwa, kodwa yonke irusi luhlobo oluthile lomhlwa.
Insimbi ene-galvanized, efakwe kwi-layer ye-zinc, ichasene kakhulu nale nkqubo. I-zinc layer ikhusela ukudibana ngokuthe ngqo phakathi kwentsimbi kunye nezinto ezisingqongileyo ezifana nokufuma kunye nomoya, ezona zinto zibangela umhlwa. Xa kusenzeka umhlwa, i-zinc idla ngokutya kuqala, ishiya intsimbi ikhuselekile.
Kutheni iZinc ibalulekile kuKhuseleko lweCorrosion
I-Zinc idlala indima ebalulekileyo ekusebenzeni kwentsimbi enamazinki ekuthinteleni irusi. Ngethuba lenkqubo ye-galvanizing, i-zinc iboshwe kwi-steel surface, yenza uluhlu olukhuselayo. Lo maleko usebenza njengesithintelo, ukugcina ukufuma kunye nomoya kude nentsimbi engaphantsi. Ngaphezu koko, i-zinc ingumbingelelo-ithetha ukuba i-corrodes ngaphambi kokuba intsimbi yenze, ikhusela isinyithi esingaphantsi kwi-oxidation. Lo matshini wokuzincama uyimfuneko kubomi obude bentsimbi enezingqimba, ngakumbi kwiindawo eziyimingeni.
Inkqubo yeGalavanizing kunye noKuchasa umhlwa
Inkqubo eyenziwa ngayo intsimbi ekhandisiweyo ibalulekile kwiipropati zayo ezikwaziyo ukumelana nomhlwa. Iinkqubo ezimbini eziphambili zisetyenziselwa ukuvelisa intsimbi ye-galvanized: i-hot-dip galvanizing kunye ne-electrogalvanizing. Indlela nganye ineenzuzo zayo kwaye isetyenziselwa izicelo ezahlukeneyo ngokuxhomekeke kwinqanaba elifunekayo lokukhusela kunye nokusetyenziswa okujoliswe kuyo.
I-Hot-Dip Galvanizing vs. Electrogalvanizing
I-Hot-dip galvanizing yeyona ndlela ixhaphakileyo nesebenzayo ekuveliseni intsimbi. Kule nkqubo, intsimbi ifakwe kwi-zinc etyhidiweyo, idala i-coating eqinileyo, ehlala ibambelele phezulu. Ubuninzi be-zinc layer bubonelela ngokhuseleko oluphezulu kwi-rust kunye ne-corrosion, okwenza kube yinto efanelekileyo kwizicelo zangaphandle kunye nezoshishino apho intsimbi ibonakaliswe kumswakama, ukungcola kunye nezinye izinto zokusingqongileyo.
I-Electrogalvanizing, ngakolunye uhlangothi, isebenzisa inkqubo ye-electrolytic ukusebenzisa i-zinc encinci kwintsimbi. Ngelixa le ndlela ibonelela ngenqanaba elilungileyo lokhuseleko, ayinamandla njenge-galvanizing yediphu eshushu. Insimbi ye-Electrogalvanized isoloko isetyenziselwa izicelo apho intsimbi iya kubonakaliswa kwiimeko ezinobunzima kwaye apho i-coating encinci iyamkeleka.
Isithintelo seZinc kunye neNdlela yokuKhusela iDini
Iipropati ezikhuselayo zetsimbi ezenziwe nge-galvanized zivela kwisithintelo esikhethekileyo se-zinc. I-zinc layer isebenza njengesikhuselo somzimba esithintela ukufuma kunye neoksijini ekufikeleleni kwintsimbi. Ukongezelela, ukuba i-coating ye-zinc ikhutshwe okanye yonakaliswe, iyaqhubeka nokukhusela intsimbi engaphantsi kwendlela yokukhusela idini. I-Zinc i-corrodes kuqala, ikhusela intsimbi ekuhlwa kwaye yandisa ixesha lokuphila kwayo.
Ixesha elingakanani intsimbi eGalvanized Mesa umhlwa
Omnye weyona mibuzo ixhaphakileyo malunga nentsimbi ekhandisiweyo kukuba ihlala ixesha elingakanani phambi kokuba iqale ukurusa. Impendulo ixhomekeke kwizinto ezininzi, kubandakanywa indawo esetyenziswa kuyo, ubukhulu be-zinc coating, kunye nenqanaba lokuchayeka kumanzi kunye nezinye izinto ezidliwayo.
Imiba yokusingqongileyo echaphazela ubomi obude
Ubomi obude bentsimbi ye-galvanized buchaphazelwa kakhulu yimiba yokusingqongileyo. Kwiindawo ezomileyo, zangaphakathi, isinyithi esinamatyholo sinokuhlala amashumi eminyaka ngaphandle kokubola okukhulu. Ngokwahlukileyo koko, indawo ezingqongileyo zangaphandle ezinomswakama ophezulu, umoya onetyuwa (njengeendawo eziselunxwemeni), okanye ungcoliseko lwemizi-mveliso lunokukhawulezisa ukuthotywa kwengubo ye-zinc.
Umzekelo, intsimbi efakwe igalvanized esetyenziswa kwindawo yokugcina imizi-mveliso enokuvezwa kancinci kukufuma inokuhlala iminyaka engama-20 ukuya kwengama-30, ngelixa intsimbi efakwe igalvanized esetyenziswa kwimimandla eselunxwemeni inokuhlala iminyaka emi-5 ukuya kweli-10 ngenxa yendalo engcolisayo yamanzi anetyuwa kunye nokufuma okuphezulu.
I-Patina ekhuselayo kunye nendlela ephuhliswa ngayo
Ngokuhamba kwexesha, intsimbi ekhandisiweyo yenza umaleko okhuselayo obizwa ngokuba yipatina. Lo maleko ukhula xa i-zinc isabelana nomoya kunye nokufuma. I-patina isebenza njengesithintelo sesibini, inika ukhuseleko olongezelelweyo kwi-corrosion. Ngokwenene, le patina inceda ukucotha inkqubo yokubola, iqinisekisa ukuba isinyithi esinamavili siyaqhubeka sisebenza kakuhle nangemva kweminyaka yokuvezwa kwezinto.
Xa intsimbi yeGalvanized Can Rust
Ngelixa intsimbi ekhandiweyo imelana kakhulu nomhlwa, kukho iimeko ezithile apho umhlwa usenokwakheka. Kubalulekile ukuqonda ezi meko ukuze kugcinwe ingqibelelo yentsimbi enamatyheli ngokuhamba kwexesha.
Imikrwelo kunye nokonakala koomatshini
Oyena nobangela uphambili womhlwa kwintsimbi yegalvanized ngumonakalo womatshini. Ukuba i-coating ye-zinc yokukhusela ikhutshwe okanye iphazamisekile, intsimbi evezwayo isengozini yokubola. Oku kuyinyani ngakumbi ukuba umkrwelo okanye umonakalo wenzeka kwindawo apho kunokuqokelelwa ukufuma okanye ungcoliseko.
Imekobume Ebungqwabalala
Kwiimeko ezingqongileyo ezirhabaxa kakhulu, ezinje ngolwandle okanye kwimizi-mveliso, intsimbi efakwe amazimba inokuba nomhlwa okhawulezileyo. Amanqanaba aphezulu etyuwa emoyeni, iikhemikhali zemizi-mveliso, kunye nezinye izinto ezidlayo zinokudiliza i-zinc layer ngokukhawuleza, nto leyo evumela ukuba kubekho umhlwa kwintsimbi evelileyo. Ngelixa intsimbi ekhandiweyo inika ukhuseleko olugqwesileyo, ezi meko zisenokufuna ukugcinwa rhoqo okanye ukugquma ezongezelelweyo zokhuselo.
Ukuthelekisa i-Galavanized Steel Coil kunye nokuqina kweShiti kwii-Applications zangempela
Zomibini iikhoyili zetsimbi kunye namaphepha ensimbi ahlala eqinile, kodwa ukusebenza kwawo kunokuhluka ngokuxhomekeka kwisicelo esithile. I-Shandong Sino Steel Co., Ltd. inikeza zombini iinketho, nganye ineenzuzo ezizodwa kumashishini ahlukeneyo.
Imizi-mveliso vs
Kwizicelo zoshishino, iikhoyili zetsimbi kunye namaphepha zisetyenziselwa iinjongo ezahlukeneyo, kubandakanywa ukuphahla, ukugquma, ukubiyela kunye namacandelo okwakhiwa. Ukuqina kwentsimbi yegalvanized kwezi zicelo kubalulekile, njengoko kufuneka imelane nokuvezwa kokufuma, iikhemikhali, kunye nobushushu obugqithisileyo.
Kwishishini lokwakha, isinyithi esinezinki sisoloko sisetyenziselwa ukuqulunqa, ukuphahla, kunye nezakhiwo zangaphandle. Ukuxhatshazwa kwe-corrosion yensimbi eyenziwe nge-galvanized kwenza kube yinto efanelekileyo kwiiprojekthi ezivezwe kwizinto, eziqinisekisa ukusebenza kwexesha elide nakwimozulu enzima.
