Ipayipi Eliyindilinga Lensimbi Eshisayo Ecwebezelayo Esezingeni Eliphezulu Elingabizi Kakhulu
amapayipi ensimbi acwiliswe ngogesi ashisayo
Ubukhulu bengqimba ye-zinc: Ngokuvamile yi-15-120μm (okulingana no-100-850g/m²). Ilungele izindawo zangaphandle, ezinomswakama, noma ezigqwalisayo njengezakhiwo ezisikiwe, izivikelo zikamasipala, amapayipi amanzi omlilo, kanye nezinhlelo zokunisela zezolimo.
amapayipi ensimbi afakwe i-electro-galvanized
Ubukhulu bengqimba ye-zinc: Ngokuvamile 5-15μm (okulingana no-30-100g/m²). Ifanelekela izimo zangaphakathi, ezingagqwali kakhulu njengezinhlaka zefenisha, izisekelo zesakhiwo ezilula, kanye nezimbobo zekhebula ezinezifakelo ezivikelwe.

Izici
1. Ukuvikelwa kabili kwengqimba ye-zinc:
Ungqimba oluqinile lwe-iron-zinc alloy (amandla okubopha aqinile) kanye nongqimba oluhlanzekile lwe-zinc kwakheka phezu kobuso, okuhlukanisa umoya nomswakama, okubambezela kakhulu ukugqwala kwamapayipi ensimbi.
2. Ukuvikelwa kwe-anode yomhlatshelo:
Ngisho noma uqweqwe lonakele kancane, i-zinc izoqala ngokugqwala (ukuvikelwa kwe-electrochemical), ivikele isisekelo sensimbi ekugugulekeni.
3. Impilo ende:
Endaweni evamile, isikhathi sokuphila singafinyelela eminyakeni engama-20-30, okude kakhulu kunemipayipi yensimbi evamile (njengoba isikhathi sokuphila kwamapayipi apendiwe singaba yiminyaka emi-3-5)
Xhumana Nathi Ukuze Uthole Imininingwane Eyengeziwe Ngamapayipi Ensimbi Ahlanganisiwe.
Ukucwilisa okushisayoipayipi elihlanganisiweAma-s asetshenziswa kabanzi ezakhiweni zokwakha (njengezinsika zefektri, izisekelo), ubunjiniyela bukamasipala (izinsika zokuvikela, izinsika zokukhanya zasemgwaqweni, amapayipi okukhipha amanzi), amandla namandla (imibhoshongo yokudlulisa, amabhuleki e-photovoltaic), izikhungo zezolimo (amathambo okugcina ukushisa, izinhlelo zokunisela), ukukhiqiza kwezimboni (amashalofu, imigudu yokungenisa umoya) kanye neminye imikhakha ngenxa yokumelana kwawo okuhle kakhulu nokugqwala, amandla aphezulu kanye nokuphila isikhathi eside. Ahlinzeka ngokuvikelwa okungenasondlo, okungabizi kakhulu futhi okuthembekile ezindaweni zangaphandle, ezinomswakama noma ezigqwalisayo kanye nokuphila kwesikhathi senkonzo esifinyelela eminyakeni engama-20-30. Ayisisombululo esithandwayo sokulwa nokugqwala sokufaka esikhundleni samapayipi ensimbi ajwayelekile.
Inqubo yokukhiqiza amapayipi ahlanganisiwe ayindilinga agqitshwe nge-galvanized ilandela lezi zinyathelo:
1. Ukwelashwa Kwangaphambi Kwezinto Ezingavuthiwe: Khetha ama-coil ensimbi angenakhabhoni ephansi, asikwe abe yimichilo enobubanzi obufanele, afakwe emanzini abandayo ukuze kususwe uqweqwe, ahlanzwe ngamanzi ahlanzekile, bese omiswa ukuze kuvinjelwe ukugqwala.
2. Ukwakha Nokushisela: Imichilo yensimbi ifakwa kumshini wokunyathelisa ojikelezayo bese igoqwa kancane kancane ibe yizicucu zamashubhu eziyindilinga. Umshini wokushisela osebenza kakhulu uncibilikisa imithungo yeshubhu bese uyicindezela bese uyiqinisa, wakhe ishubhu eliyindilinga elinesikhumba esimnyama. Ngemva kokupholisa ngamanzi, amashubhu ayalinganiswa futhi alungiswe, bese enqunywa ngobude njengoba kudingeka.
3. Ukwakhiwa Kwe-Galvanizing Engaphezulu(i-galvanizing ingahlukaniswa ngokuthi i-hot-dip galvanizing (i-hot-dip galvanizing) kanye ne-cold-dip galvanizing (i-electrogalvanizing), kanti i-hot-dip galvanizing iyindlela evelele embonini (inikeza umphumela wokuvimbela ukugqwala osebenza kahle kakhulu)): Amapayipi ahlanganisiwe adlula ekuhlungeni kwesibili ukuze kususwe ukungcola, acwiliswe ku-flux ye-galvanizing, bese ecwiliswa ku-zinc encibilikisiwe ku-440-460°C ukuze kwakhiwe ungqimba lwe-zinc alloy. I-zinc eningi isuswa ngommese womoya, bese ipholiswa. (I-cold-dip galvanizing iwungqimba lwe-zinc olune-electrodeposited futhi aluvamile ukusetshenziswa.)
4. Ukuhlolwa Nokupakisha: Hlola ungqimba lwezinki kanye nosayizi, kala ukunamathela kanye nokumelana nokugqwala, hlela bese uhlanganisa imikhiqizo efanelekile, bese uyibeka endaweni yokugcina ngamalebula.
Inqubo yokukhiqiza amapayipi ayindilinga angenamthungo agqitshwe nge-galvanized ilandela lezi zinyathelo:
1. Ukwelashwa Kwangaphambi Kwezinto Eziluhlaza: Ama-billet ensimbi angenamthungo (ikakhulukazi insimbi engenakhabhoni ephansi) ayakhethwa, anqunywe abe ubude obungaguquki, bese kususwa isikali se-oxide kanye nokungcola. Ama-billet abe eseshiswa afike ezingeni lokushisa elifanele ukuze abhoboze.
2. Ukubhoboza: Ama-billet afudumele afakwa emapayipini angenalutho ngomshini wokubhoboza. Amapayipi abe esedluliswa ngomshini wokugoqa ipayipi ukuze kulungiswe ukujiya kodonga kanye nokuzungeza. Ububanzi bangaphandle bulungiswa ngomshini wokukala ukuze kwakhiwe amapayipi amnyama ajwayelekile angenamthungo. Ngemva kokupholisa, amapayipi anqunywa ngobude.
3. Ukuhlanganisa nge-galvanizing: Amapayipi amnyama angenamthungo adlula ekwelashweni kwesibili kokukhipha ungqimba lwe-oxide. Bese ehlanzwa ngamanzi bese ecwiliswa ku-ejenti yokugaya. Bese ecwiliswa ku-zinc encibilikisiwe engu-440-460°C ukuze kwakheke ungqimba lwe-zinc-iron alloy. I-zinc eningi isuswa ngommese womoya, bese amapayipi epholiswa. (I-cold galvanizing iyinqubo yokufaka i-electrode futhi ayivamile ukusetshenziswa.)
4. Ukuhlolwa Nokupakisha: Ukufana kanye nokunamathela kwengubo ye-zinc kuyahlolwa, kanye nobukhulu bamapayipi. Amapayipi avunyiwe abe esehlelwa, ahlanganiswe, afakwe ilebula, futhi agcinwe ukuqinisekisa ukuthi ahlangabezana nezindinganiso zokuvimbela ukugqwala kanye nokusebenza kwemishini.
Izindlela zokuhamba zemikhiqizo zifaka phakathi ezokuthutha zomgwaqo, zesitimela, zasolwandle, noma zezindlela eziningi zokuhamba, ngokusekelwe ezidingweni zamakhasimende.
Ezokuthutha ngomgwaqo, kusetshenziswa amaloli (isb., ama-flatbed), ziyaguquguquka emabangeni amafushane aphakathi nendawo, okuvumela ukulethwa ngqo ezindaweni/ezindaweni zokugcina impahla ngokulayisha/ukukhulula okulula, okulungele ama-oda amancane noma aphuthumayo kodwa abiza kakhulu emabangeni amade.
Ezokuthutha ngesitimela zithembele ezitimeleni zempahla (isb., izinqola ezimboziwe/ezivulekile ezinezintambo ezingangenisi imvula), ezifanelekela ukuthunyelwa okude, okunomthamo omkhulu ngezindleko eziphansi kanye nokuthembeka okuphezulu, kodwa zidinga ukuthunyelwa okufushane.
Ukuthuthwa kwamanzi (ngaphakathi nezwe/olwandle) ngemikhumbi yempahla (isb., imikhumbi emikhulu/yesitsha) kunezindleko eziphansi kakhulu, kufakwa amabanga amade, ukuthuthwa okukhulu ogwini/ogwini lomfula, kodwa kunqunyelwe echwebeni/emzileni futhi kuhamba kancane.
Ezokuthutha eziningi (isb., isitimela+umgwaqo, ulwandle+umgwaqo) zilinganisela izindleko kanye nesikhathi, zifanelekela ama-oda ahamba ngezifunda, amabanga amade, ahamba ngendlu ngendlu anenani eliphezulu.
1. Angakanani amanani akho?
Amanani ethu angashintsha kuye ngokuthi ukunikezwa kwempahla kuyatholakala yini kanye nezinye izici zemakethe. Sizokuthumelela uhlu lwamanani olubuyekeziwe ngemuva kokuxhumana nenkampani yakho.
nathi ukuze uthole ulwazi olwengeziwe.
2. Ingabe unenani elincane kakhulu le-oda?
Yebo, sidinga ukuthi wonke ama-oda aphesheya abe nenani elincane eliqhubekayo le-oda. Uma ufuna ukuthengisa kabusha kodwa ngamanani amancane kakhulu, sincoma ukuthi uhlole iwebhusayithi yethu.
3. Ungakwazi yini ukunikeza amadokhumenti afanele?
Yebo, singanikeza imibhalo eminingi kufaka phakathi Izitifiketi Zokuhlaziya/Ukuhambisana; Umshwalense; Umsuka, kanye neminye imibhalo yokuthumela ngaphandle lapho kudingeka khona.
4. Singakanani isikhathi esimaphakathi sokuhola?
Kumasampula, isikhathi sokuhola cishe siyizinsuku eziyi-7. Ekukhiqizweni ngobuningi, isikhathi sokuhola siyizinsuku ezi-5-20 ngemuva kokuthola inkokhelo yediphozithi. Izikhathi zokuhola ziqala ukusebenza uma
(1) sesiyitholile idiphozithi yakho, futhi (2) sinemvume yakho yokugcina yemikhiqizo yakho. Uma izikhathi zethu zokukhokha zingasebenzi ngesikhathi sakho sokugcina, sicela ubuyekeze izidingo zakho ngokuthengisa kwakho. Kuzo zonke izimo sizozama ukuhlangabezana nezidingo zakho. Ezimweni eziningi siyakwazi ukwenza kanjalo.
5. Yiziphi izinhlobo zezindlela zokukhokha ozamukelayo?
U-30% kusengaphambili nge-T/T, u-70% uzoba ngaphambi kokuthunyelwa okuyisisekelo ku-FOB; u-30% kusengaphambili nge-T/T, u-70% uma kuqhathaniswa nekhophi ye-BL eyisisekelo ku-CIF.
