Intshayelelo
Kwindawo yokwakhiwa kunye nokuveliswa, ukuqina kwezinto eziphathekayo kwiimeko zemozulu ezinzima kubaluleke kakhulu. Izakhiwo zihlala zichanabeke kwizinto ezifana nemvula, ikhephu, ukufuma, nezinto ezingcolisa umzimba ezinokubeka esichengeni ingqibelelo yazo ekuhambeni kwexesha. Enye imathiriyeli eye yamelana novavanyo lwexesha ekuxhathiseni ezi ziphumo ziyingozi lishiti lentsimbi editshiweyo eshushu. Olu luhlu lwentsimbi lunika isisombululo esomeleleyo kumashishini afuna ixesha elide kunye nokuthembeka kwiimveliso zabo. Inkqubo yokwenziwa kwegalvanization yongeza ukukwazi kwentsimbi ukumelana nemekobume eyonakalisayo, iyenze ibe lolona khetho lufanelekileyo Iishiti zeNtsimbi eGalvanized ezisetyenziswa kwizicelo ezahlukeneyo.
Ukuqonda aMashiti eNtsimbi aDidiweyo ashushu
Amashiti entsimbi aditshiweyo ashushu aveliswa ngokuntywiliselwa intsimbi kwizinki etyhidiweyo, nto leyo ekhokelela kwiqhina lesinyithi phakathi kwezinki nentsimbi. Le nkqubo idala isakhiwo esinemigangatho emithathu ebandakanya intsimbi yentsimbi, i-intermetallic layer, kunye ne-coating ye-zinc yangaphandle. I-zinc isebenza njengesithintelo sokukhusela, ukuthintela izinto ezinobungozi ekufikeleleni kwi-substrate yensimbi. Ibhondi ye-metallurgical iqinisekisa ukuba i-coating iqinile kwaye ichasene nomonakalo womatshini ngexesha lokuphatha kunye nenkonzo.
Inkqubo yeGalavanization
Inkqubo yokwenziwa kwegalvanization ibandakanya amanyathelo abalulekileyo okuqinisekisa ubulunga obuphezulu bokugquma. Ekuqaleni, amashidi ensimbi ahamba ngokulungiswa komhlaba, okubandakanya ukuhlanjululwa, ukucolwa, kunye nokuguquguquka ukususa ukungcola kunye ne-oxides. Olu lungiselelo lubalulekile ekufezekiseni umaleko we-zinc ofanayo kunye nokubambelelayo. Emva kokulungiswa, amaphepha afakwa kwibhafu ye-zinc etyhidiweyo eshushu malunga ne-450 ° C (842 ° F). Emva kokuhoxiswa, i-zinc iphendula ngentsimbi ukuze yenze iileyile zokukhusela. Amaphepha ke ayapholiswa kwaye ahlolwe ukutyeba kunye nokuhambelana.
IiNdlela zokuTyakala kunye neMozulu
Ukonakala yinkqubo yendalo eyenzeka xa iintsimbi zisabelana nezinto zokusingqongileyo, nto leyo ekhokelela ekuwohlokeni kwemathiriyeli. Kwiimeko zemozulu ezimaxongo, izinto ezifana nokufuma, ioksijini, ukuguquguquka kwamaqondo obushushu, kunye nezingcolisi zinyusa izinga lokurhwalala. Ngokomzekelo, kwimimandla engaselunxwemeni, isitshizi setyuwa sizisa iikloridi eziyonakalisa kakhulu intsimbi. Imimandla yemizi-mveliso inokuba namanqanaba aphezulu e-sulphur dioxide, enegalelo kwimvula eneasidi, eqhubela phambili ukudleka. Ukuqonda ezi ndlela ziyimfuneko ekukhetheni izixhobo ezinokuxhathisa imeko-bume enobundlongondlongo.
Njani iNtsimbi eyiGalvanized kuMhlwa
Ukuxhathisa okukhethekileyo kwentsimbi yesinyithi kwi-corrosion ivela kwiipropathi zokukhusela ze-zinc coating. I-zinc isebenza njengesithintelo somzimba, ukukhusela intsimbi engaphantsi kumswakama kunye ne-oxygen. Ngaphezu koko, i-zinc inamandla aphezulu e-electrochemical kunentsimbi, evumela ukuba yenze idini. Ukuba i-coating ikrwelwe okanye yonakaliswe, i-zinc ikhetha ngokufanelekileyo i-corrodes, ikhusela iindawo zetsimbi eziveziweyo, into eyaziwa ngokuba yi-galvanic okanye i-cathodic ukukhusela.
Ukukhuselwa komqobo
Uluhlu lwangaphandle lwe-zinc lubonelela ngomqobo ongenakuthintelwa kwizinto ezisingqongileyo. Lo mqobo uthintela izinto ezidliwayo ukuba ziqhagamshelane nomphezulu wentsimbi. Ukunyaniseka kolu maleko kubalulekile ekomeleleni kwexesha elide, njengoko kuthoba kakhulu inkqubo yokubola. Iimpawu zokuncamathelisa ze-zinc ziqinisekisa ukuba zihlala zikhuselekile naphantsi koxinzelelo lomatshini.
Ukukhuselwa kweGalvanic
Kwiimeko apho i-zinc layer iphazamiseka, ukukhuselwa kwe-galvanic kuya kudlala. Ubudlelwane be-electrochemical phakathi kwe-zinc kunye nentsimbi bubangela ukuba i-zinc i-oxidize ngokukhethekileyo, ngaloo ndlela igcina intsimbi. Oku kuziphatha kokuzincama kwandisa ixesha lokuphila kwecandelo lentsimbi, okwenza amashiti ensimbi afakwe emanzini ashushu afaneleke ngokukodwa kwiindawo ezinzima.
Ukusebenza kwiNdawo eziBungqwabalala
Amaphepha entsimbi aditshiwe ashushu avavanyiwe kwaye angqinwa ukuba asebenza kakuhle kakhulu kwiimeko ezahlukeneyo ezinzima. Ukuguquguquka kwabo kubenza babe yimathiriyeli ekhethwayo kumacandelo amaninzi.
Imekobume engaseluNxwemeni
Kwimimandla engaselunxwemeni, ubukho bomoya onetyuwa eninzi kwandisa umngcipheko wokudleka. Amaphepha ensimbi enziwe ngesinyithi anika ukhuseleko olongeziweyo ngenxa yokuqina kwe-zinc. Uphononongo lubonise ukuba i-zinc layer inokumelana nemiphumo eyingozi yekloridi, inika ubomi obufikelela kwiminyaka engama-75 kwezinye iimeko. Oku komelela kubenza balungele iziseko zophuhliso zaselwandle, ezifana needokhi, iibhulorho, kunye nezakhiwo eziselunxwemeni.
Ubume boShishino
Imimandla yemizi mveliso ihlala inemigxinano ephezulu yezingcolisi ezifana nesulphur dioxide kunye nenitrogen oxides, ezikhokelela kwimvula eneasidi. Ukumelana nentsimbi ye-galvanized kwiimeko ze-acidic kuqinisekisa ukuba amacandelo esakhiwo agcina ingqibelelo yawo ekuhambeni kwexesha. Ukusebenza okungaguqukiyo kwi-atmospheres enobundlongondlongo kwenza ukuba amashiti ensimbi abe nexabiso elikhulu kwiifektri kunye nokufakelwa kwamashishini.
Ubume baseMaphandleni
Kwiindawo zasemaphandleni, amashidi ensimbi abonakaliswe ngeendlela ezahlukeneyo zemozulu, kubandakanywa umswakama ophezulu kunye nokutshintsha kweqondo lokushisa. I-zinc ikhusela ngokufanelekileyo kumhlwa kunye nomhlwa, iyenza ifaneleke kwizakhiwo zezolimo, ukubiyela kunye nezixhobo zokusebenza. Ubude obude bensimbi ye-galvanized kwezi zicwangciso kunciphisa isidingo sokutshintshwa rhoqo kunye nokugcinwa.
Ubomi obude kunye noLondolozo
Enye yeenzuzo ezibalulekileyo zamaphepha entsimbi aditshiweyo ashushu bubomi babo benkonzo ende kunye nokugcinwa okuncinci. Uluhlu olukhuselayo lwezinc lunokubonelela ngokuxhathisa ukubola amashumi eminyaka, kuxhomekeke kwindawo kunye nobukhulu bengubo. Uhlolo lwesiqhelo lwanele ukuqinisekisa ukuba imathiriyeli ihlala ikwimeko entle. Xa ukugcinwa kuyadingeka, kudla ngokuthe ngqo, okubandakanya ukudibanisa kwe-coating ye-zinc ukulungisa nayiphi na indawo eyonakalisiweyo.
Izinto eziluncedo kwezoQoqosho kunye neziSebenzayo
Ukusuka kumbono wezoqoqosho, amashiti ensimbi anikezela ngeendleko zokonga ixesha elide. Utyalo-mali lokuqala luhlawulelwa ziindleko zokuyilungisa ezicuthiweyo kunye nobomi benkonzo obandisiweyo. Oku kubenza babe sisisombululo esinexabiso elisebenzayo kubavelisi, abasasazi, kunye nabasebenzisi bokugqibela. Ubuninzi beeshiti zetsimbi zensimbi zivumela ukuba zisetyenziswe kuluhlu olubanzi lwezicelo, ukusuka kwiindawo zemoto ukuya kumacandelo okwakhiwa kwezakhiwo.
Izicelo kuwo wonke amaShishini
Ukusetyenziswa kwamaphepha entsimbi aphekiweyo kugubungela amashishini amaninzi. Ekwakhiweni, zibalulekile ekufuleni, ukugquma, kunye nefreyim ngenxa yamandla azo kunye nokumelana nemozulu. Umzi-mveliso weemoto uzisebenzisela iipaneli zomzimba kunye namalungu ekhareji engaphantsi, exhamla ekomeleleni kwazo kunye neempawu ezikhaphukhaphu. Ukongeza, icandelo lamandla lisebenzisa intsimbi ekhandiweyo kwiinqaba zothumelo kunye nee turbines zomoya, apho ukuchasana nezinto zokusingqongileyo kubaluleke kakhulu.
Ubuchwephesha obusakhulayo kwiGalvanization
Inkqubela phambili kwiteknoloji ye-galvanization iyaqhubeka nokuphucula ukusebenza kwamaphepha ensimbi. Ubuchule obutsha obufana ne-alloying zinc nezinye iintsimbi ezifana ne-aluminiyam kunye ne-magnesium ikhokelele ekuphuculeni ukuxhathisa umhlwa. Ezi zambatho zesizukulwana esilandelayo zinika ukhuseleko oluphezulu kwiindawo ezinobundlobongela ngakumbi, ukwandisa usetyenziso olunokwenzeka lwentsimbi.
Ukuqwalaselwa kokusingqongileyo
Uzinzo lubaluleke kakhulu ekukhetheni izinto eziphathekayo. Intsimbi yegalvanized i-100% iphinda isetyenziswe, kwaye inkqubo ye-galvanization iye yavela ukuze ibe yinto ehambelana nokusingqongileyo. Izityalo zanamhlanje zisebenzisa amanyathelo okunciphisa ukukhutshwa kunye nokuphinda kusetyenziswe i-zinc kunye nezinye iimveliso. Oku kuzibophelela kulawulo lokusingqongileyo kwenza ukuba amashiti entsimbi aditshiwe ashushu abe luxanduva lokukhetha iiprojekthi ze-eco-conscious.
Ukuqukumbela
Ukomelela kwamashiti entsimbi aditshiwe ashushu kwimozulu embi kububungqina bokugqwesa kwabo kwezobunjineli kunye nesayensi. Ukudibanisa umqobo kunye nokukhuselwa kwe-galvanic okubonelelwa nge-coating ye-zinc kuqinisekisa ukuhlala ixesha elide kunye nokuthembeka. Kwiifektri, abasasazi, kunye namashishini afuna izinto ezinikezela ukusebenza okuphezulu kunye nokugcinwa okuncinci, amashiti ensimbi amele ukhetho olufanelekileyo. Irekhodi yabo eqinisekisiweyo, kunye nenkqubela phambili yetekhnoloji, iyaqhubeka nokubenza bafaneleke kwiimeko zanamhlanje ezibangwayo.
