1. Koj yuav tsum ua li cas tam sim yog tias koj pom cov galvanized coils tau ntub thiab xeb?
Ua ntej, koj yuav tsum ntsuas qhov hnyav ntawm cov xeb ua ntej yuav ua li cas. Yog tias tsuas yog dej tau nkag mus rau hauv lub ntim lossis muaj cov hmoov dawb me ntsis ntawm qhov chaw, qhov tseem ceeb tshaj plaws uas yuav tsum tau ua yog kom tshem tawm cov ntim tam sim ntawd thiab kis cov galvanized coils tawm hauv qhov dej - qhov chaw cua kom huab cua qhuav. Tom qab ziab, cov hmoov xeb dawb tuaj yeem raug tshem tawm los ntawm kev so nrog ib daim ntaub qhuav. Thaum lub sijhawm ua haujlwm no, thov ceev faj tsis txhob siv cov txhuam hlau lossis cov ntawv xuab zeb ntxhib los txhuam kom zoo, vim qhov no yuav ua rau cov zinc txheej puas. Rau cov xeb dawb me ntsis, muaj qhov tshwj xeeb: zinc hydroxide hauv cov xim dawb dawb yuav hnov mob nrog huab cua tom qab qhov cua, hloov mus rau hauv zinc carbonate, uas muaj kev tiv thaiv zoo. Hauv qhov no, tej zaum nws yuav tsis tsim nyog los so nws tawm.
2.Yuav ua li cas yog tias cov xeb dawb hnyav thiab tsis tuaj yeem tshem tawm los ntawm tsuas yog so nrog daim ntaub qhuav?
Rau nruab nrab mus rau loj xeb dawb, yuav tsum muaj kev tiv thaiv ntau dua. Koj tuaj yeem siv cov txhuam nylon tawv los yog cov ntawv xuab zeb zoo (1200 grit lossis siab dua pom zoo) los maj mam txhuam cov hmoov txhuam hniav. Yog tias cov xeb tawv tawv, koj tuaj yeem siv cov kua qaub me me rau kev kho tshuaj. Sib tov cov kua txiv hmab txiv ntoo dawb thiab dej hauv qhov sib piv 1: 3, siv rau hauv cov xeb, tawm rau 5 mus rau 10 feeb, tom qab ntawd txhuam nrog txhuam txhuam txhuam. Thaum kawg, yaug kom huv si nrog dej kom ntau thiab cia kom qhuav tag.
3.Kuv yuav ua li cas yog tias cov txheej galvanized tau tawg hnyav heev, nthuav tawm cov hlau hauv qab thiab ua rau xeb liab?
Thaum pom cov xeb liab, nws qhia tau hais tias cov zinc txheej tau sib sib zog nqus corroded, thiab qhov xwm txheej hnyav heev. Kev so yooj yim yuav tsis ua haujlwm. Ua ntej, kom huv si tshem tawm cov xeb liab thiab ib puag ncig puas zinc txheej nrog cov ntawv xuab zeb zoo. Tom qab ntawd, siv lub txias txias - tshuaj tsuag zinc kho cov xim uas muaj siab - purity zinc hmoov los kho qhov chaw, ua kom muaj kev tiv thaiv tiav tom qab kho.
4. Vim li cas qee zaum nws tsis tas yuav txhawj xeeb ntau dhau ntawm cov xeb dawb me ntsis ntawm galvanized coils?
Cov xeb dawb me ntsis feem ntau yog cov tshuaj tiv thaiv ib txwm nyob qhov twg zinc txheej nquag "saib nws tus kheej" los tiv thaiv cov hlau. Zinc yog tshuaj lom neeg ntau dua li cov hlau, nyiam dua cov dej noo thiab oxygen los tiv thaiv lub hauv paus hlau substrate. Txawm hais tias lub ntim nthuav dav ntawm cov hmoov dawb xeb tuaj yeem ua rau corrosion tshwm sim hnyav, qhov poob ntawm zinc txheej yog feem ntau me me. Ntxiv mus, nyob rau hauv qhov chaw zoo -ventilated ib puag ncig, cov xim dawb dawb tuaj yeem ua rau cov pa roj carbon dioxide ntxiv los ua cov yeeb yaj kiab tiv thaiv ntom ntom ntawm cov zinc carbonate, uas ua tau pab txhim kho ntev - lub sij hawm corrosion kuj.
5. Dab tsi yog qhov kev daws teeb meem rau xeb los ntawm ya raws hauv galvanized coils?
Ntev -lub sij hawm tiv thaiv xeb hinges ntawm kev tiv thaiv. Lub hauv paus ua rau rusting nyob rau hauv galvanized coils vim ya raws yog feem ntau heev high humidity thiab tsis zoo cua nyob rau hauv lub cia ib puag ncig. Cov lus pom zoo: Khaws cov av noo nyob rau hauv lub tsev qiv ntawv qis dua 70%, thiab khaws cov khoom nce siab uas siv cov sawb ntoo lossis ntoo racks tiv thaiv kev sib cuag nrog hauv av. Thaum yuav khoom, xaiv cov galvanized coils uas tau dhau los ua kev kho mob passivation, vim tias cov yeeb yaj kiab passivation ntawm lawv qhov chaw ua haujlwm tau zoo ncua kev tsim cov xeb dawb. Tom qab kev xa khoom, siv thawj -hauv, ua ntej- tawm (FIFO) system kom luv luv lub voj voog khoom. Ua ntej warehouses, xyuas cov zaj duab xis passivation, thiab xyuas kom meej tias lub ntim yog zoo thaum lub sij hawm thauj mus los thiab cia. Kuj tseem nco ntsoov tias qhov zoo{10}}passivated galvanized coils muaj qhov pheej hmoo ntawm xeb dawb.
