Ukuqina kwepuleti elishumekiwe le-hot-dip? 

Ake sinqamule i-marketing fluff. Uma othile ebuza ngokuqina kwamapuleti ashumekwe ediphu ashisayo, ngokuvamile usuke efuna impendulo yeminyaka engu-50+ evamile. Iqiniso liwukuthi messier. Akukhona nje ngokuqina kwe-zinc enamathela; kumayelana nokuthi kwenzekani kusukela lapho ipuleti lishiya igedlela kuze kube yilapho ligqitshwa kukhonkolo futhi likhohliwe amashumi eminyaka. Ngike ngabona amapuleti ehluleka eminyakeni eyi-10 kanti amanye abukeka emsulwa ngemuva kweminyaka engama-30, futhi umehluko uvame ukuza emininingwaneni okungekho muntu okhuluma ngayo kumashidi athile.

Igedlela Akuwona Umugqa Wokuqeda

Izingxoxo eziningi ziqala futhi zigcine ngenqubo yokufaka ama-galvanizing. I-ASTM A123, ukujiya kokugqoka, konke lokho. Impela, leso yisisekelo. Kodwa ngike ngabuka amapuleti ewonakala egcekeni ngaphambi kokuthi athunyelwe. Ukupakisha kusha eketelani ngaphandle kwe-dunage efanele? Ugaya i-coating ezindaweni zokuxhumana. Ngikhumbula iqoqo lephrojekthi yebhuloho lapho kwakudingeka senqabe i-pallet ngoba amakhona ayengenalutho ngenxa yokuphatha kabi. I-galvanizer ihlangabezane ne-spec, kodwa i ukuqina ibekwe engcupheni ngaphambi kokufakwa. Umcabango wokuthi ukwenza izikhali kuyizikhali zokugcina, ezingaguquki kuyiphutha lokuqala.

Bese kuba khona isitoreji. Uma ugcina lezi ngaphandle izinyanga, uqala iwashi endaweni yokugcina emanzi (ukugqwala okumhlophe). Ikakhulukazi iyizimonyo, kodwa ikhuluma ngokuntula ukunakekelwa ochungechungeni lokugcinwa. Umkhiqizi omuhle noma umphakeli, njenge-Handan Zitai Fastener, uyakuqonda lokhu. Indawo yabo e-Yongnian, leyo hub enkulu yokubopha, isho ukuthi bahambisa umkhiqizo ngokushesha. Ukuba seduze kwezitimela ezinkulu kanye namanethiwekhi omgwaqo njengolayini weBeijing-Guangzhou akuyona nje indawo yokuthengisa; kusho ukuthi amapuleti achitha isikhathi esincane ehlezi ezimeni eziguquguqukayo, okuthinta ngokuqondile ubuqotho bengubo oyikhokhele.

Ukushiselwa kwama-studs noma amahange ngemva kokugalela kungenye indlela ebalulekile. Kufanele uphinde uvule indawo ethinteke ukushisa. Ngike ngaba kumasayithi lapho basebenzisa upende ocebile zinc njengendlela yokuthinta. Endaweni epholile, mhlawumbe ibamba. Ezindaweni zikasawoti ezisogwini noma ezincibilikayo, leso sichibi sihluleka ngokushesha, sidala indawo eqondile yokugqwala ukuze ihlasele isisekelo sensimbi. I Ipuleti elishumekiwe kuwuhlelo, hhayi nje ucezu lwensimbi oluyisicaba.

Thela Ukhonkolo: Lapho I-Theory Ihlangana Nezinxushunxushu

Yilapho ipuleti lakho elicaciswe kahle lihlolwa khona. I-chemistry yekhonkolo ibaluleke kakhulu kunalokho abantu abakucabangayo. Izingxube ze-chloride eziphezulu ziwumbulali. Ngisebenze kuphrojekthi yegalaji yokupaka lapho ukuhlanganiswa kwamandla okuqala ... kunolaka. Sabona ukuqhuma kwe-zinc enamathela kungakapheli unyaka. I-galvanizing yayizocacisa, kodwa indawo ekhonkolo yayinobutha.

Isenzo somzimba sokuthulula sinonya. Ama-Vibrator angalimaza ipuleti uma esunduzwa aqondane nalo. Ngikhumbula isisekelo sekholomu lapho isidlidlizi sachopha khona i-zinc onqenqemeni lokushumeka. Kwakubonakala kuncane, kodwa kwakha indlela. I I-hot-cthessited galvanized ukunamathela kuyadela, ngakho-ke ukuphulwa kwenza isivikelo sibe sasendaweni. Lokho kuhle kuze kube yilapho ukuphulwa kusesimweni esibucayi sokucindezeleka, njengokuzungeze i-anchor stud.

Ukujula kwekhava kungenye yakudala. Ipuleti libekwe kahle ephepheni. Esizeni, amakheji e-rebar aguquguquka, ukugeleza kukakhonkolo, futhi kungazelelwe ikhava yakho engu-50mm iba ngu-30mm. Kulowo mkhawulo, i-carbonation ifinyelela ipuleti ngokushesha. Endaweni yekhonkrithi ye-carbonated, i-zinc idlula, kodwa uma ikhava ingahambisani, uthola izimo ezihlukile. Akuvamile ukwehluleka okufanayo; iqala endaweni ebuthaka.

Ukufiphala Okude: Ukuthi Kubukeka Kanjani Ukuqina Empeleni

Ukuqina akukhona ukudlula/ukufeyila kanambambili. Kusetshenziswa kancane kancane ungqimba lwezinc. Kukhonkolo omuhle, ominyene, one-chloride ephansi, i-zinc yakha ama-zincates azinzile futhi ehlisa umoya. Ingahlala impilo yesakhiwo. Inkinga asivamile ukuba nezimo eziphelele. Ngibuyekeza imibiko yokuhlola evela ezinhlakeni ezindala. Amapuleti awagqwalile; abonisa i-pitting yendawo noma amabala emugqeni ongaphezulu okhonkolo, ngokuvamile lapho umswakama unamathela khona njalo.

Icala elilodwa eliqondile: umzila wokuhlanza amanzi angcolile. Amapuleti ayebukeka emuhle ngaphandle kwalapho ukujiya kwamapayipi angaphezulu kwakuhlala kuconsela engxenyeni efanayo yomugqa wosimende. Lowo mjikelezo omanzi/omile njalo wadala iseli lokugqwala. I-zinc yaqedwa lapho ngemva kweminyaka engaba ngu-15, nokugqwala kwensimbi encane. Ipuleti lonke lalilungile. Ngakho, i ukuqina Iminyaka engu-15 noma engu-50? Kuya nge-micro-imvelo.

Yingakho nginokungabaza ukuhlolwa kwelebhu okusheshisiwe. Balingisa ukuhlasela okufanayo. Impilo yangempela imayelana namaphutha wendawo, ukubekezelela ukwakhiwa, kanye nezindawo zemvelo. Umphakeli ovele adayisele ipuleti elisezingeni akakuniki isithombe esigcwele. Udinga umuntu ocabanga ngesicelo. Ihlola isayithi like zitasteners.com, uyabona ukuthi bagxile ochungechungeni lwezokukhiqiza kanye nempahla. Kumakhi, lokho kwethembeka okuphezulu komfula kukhulu—kususa okuhlukile okukodwa okukhulu. Ukwazi amapuleti akho aqhamuke kusizinda sokukhiqiza esifana ne-Yongnian ngaphandle kokubanjwa ezindaweni eziningi zokudlulisa kuyisici esibambekayo sokuqina.

Lapho I-Zinc Eningi Ingeyona Isixazululo

I-reflex evamile ukucacisa i-coating enzima kakhulu. Izigidi eziningi, iminyaka eminingi. Kodwa epuletini elishumekiwe elinezikhonkwane ezishiselwe, ukunamathela okuminyene ngokweqile kungaba brittle futhi kuthambekele ekuqhekekeni ngesikhathi sokuphatha noma ukubekwa kukakhonkolo. Ngabona kuqhuma. Kukhona indaba emnandi. Futhi, i-coating ewugqinsi kakhulu ingathinta ukulingana nokuxhumeka okubekezelelana okuqinile. Ngezinye izikhathi, ukunamathela okujwayelekile okungaguquki, okusetshenziswa kahle kudlula okujiyile, okungajwayelekile.

Okuhlukile akuhlali kungenasici. Kuzinhlelo zokusebenza eziningi, lokho kuyaqina. Ipuleti eliqinile le-hot-dip galvanized, elinokunaka kwemininingwane yangemuva kokuvuthwa, libiza ngendlela emangalisayo. Okubalulekile wukuphatha njengenqubo, hhayi umkhiqizo. Kuwukwenza, ukugalela, ukuphatha, ukugcinwa, ukufakwa, nokubekwa kukakhonkolo. Ikhefu kulelo ketango ikhefu in the ukuqina.

Sizame ama-duplex coatings (galvanizing + powder coat) ekushumekeni kwezakhiwo okuveziwe kanye. Iphupho elibi. Isibopho sikakhonkolo sasikhohlisayo, futhi noma iyiphi i-chip ngesikhathi sokuthululwa yayiyisicupho somswakama. Ibuyele ku-hot-dip evamile. Kwesinye isikhathi ikhambi elijwayelekile, elenziwa ngokunaka okwedlulele emininingwaneni, lihlala isikhathi eside kakhulu.

I-Takeaway: Kuyinqubo, Hhayi Umkhiqizo

Ngakho, buyela embuzweni wokuqala. Ukuqina kwepuleti elishumekiwe le-hot-dip lincane mayelana nepuleti ngokwalo futhi okuningi mayelana nesistimu eyingxenye yalo. Ungathola ipuleti elifaneleka kakhulu endaweni enkulu yokukhiqiza efana nalena u-Handan Zitai asebenza kuyo, kodwa uma ithimba lakho liyiphatha njengensimbi eyinsimbi, ulahlekile.

Ukwahlulela kochwepheshe kuza ngokucacisa hhayi kuphela ukunamathela, kodwa izidingo zokuphatha, imiyalelo yesitoreji, namanothi okufaka. Kusekukhetheni abahlinzeki abayingxenye ye-ecosystem yezimboni edidiyelwe—lapho amapuleti asuka eketela aye kwelinye iloli aye endaweni ngaphandle komsindo omncane—ngoba lokho kunciphisa izindawo eziyingozi.

Ekugcineni, ukuqina kuyatholwa, akucacisiwe. Isamba sezinqumo eziyikhulu ezincane, ezilungile kusukela ekuklanyeni kuya ekuthululeni. I-hot-dip galvanizing iyisivikelo sakho sokuqala esingcono kakhulu, kodwa akuyona inkambu yokuphoqelela. Kuyingqimba yomhlatshelo obude bayo bokuphila bunqunywa ukuthi uyivikela kahle kangakanani, isikhathi eside ngemva kokuba ishiye i-rack ye-galvanizer.
