Thaum cov thawv khib nyiab raug nug, muaj ntau txoj hauv kev los piav qhia txog lawv: hlau khib nyiab, steel khib nyiab, galvanized bins, steel khib nyiab, kub dip galvanized khib nyiab ntim, thiab ntau, ntau ntxiv. Thaum xub thawj siab ib muag, lawv txhua tus zoo li qub, tab sis cov no yog cov thawv sib txawv raws li lawv hom kev tsim khoom. Nyeem rau kom paub ntau ntxiv txog cov txheej txheem galvanization thiab nws qhov tseem ceeb hauv kev tsim cov ntim khoom pov tseg.
Galvanization yog dab tsi?
Cov hlau thiab hlau yog cov hlau corrosive yog tias tsis tiv thaiv kom raug. Lawv zoo li tsim xeb uas tshwm sim los ntawm kev raug rau cov ntsiab lus, thiab qib xeb feem ntau nyob ntawm ib puag ncig cov khoom tso rau hauv.
Galvanization yog paub los tiv thaiv corrosive nto los ntawm kev puas tsuaj. Nws yog cov txheej txheem tshuaj uas tiv thaiv zinc txheej yog siv rau cov hlau lossis hlau los tiv thaiv lawv los ntawm kev xeb thiab xeb ua ntej.
Ib qho zoo tshaj plaws galvanization txoj kev yog kub-dip galvanization, nyob rau hauv uas tag nrho cov hlau nto yog dipped rau hauv molten zinc, li no tag nrho them nrog ib txheej ntawm zinc melted nyob rau hauv qhov kub thiab txias kom nws kub tuab kua.
Zinc yog siv vim nws tiv taus corrosion heev, yog li npog hlau nrog nws txuas nws lub neej thiab tiv thaiv lub hauv paus hlau. Cov txheej txheem ntxiv ntawm galvanization entails alloying zinc rau cov hlau, yog li ua rau kev tiv thaiv cathodic, uas cov hlau raug rau qhov kev puas tsuaj yuav ua rau xeb ntau dua - zoo ib yam li kev txhaj tshuaj rau tib neeg thiab tsiaj txhu. Txoj kev no, kev tiv thaiv cathodic yuav kav ntev npaum li cas muaj cov zinc txheej ntawm cov khoom nto.
Puas muaj lwm txoj hauv kev?
Galvanization tsis yog tib txoj kev los tiv thaiv corrosive nto los ntawm xeb. Lwm txoj hauv kev los tiv thaiv cov khoom siv hlau thiab tooj dag tau siv ntev ua ntej galvanization tau tsim.
Qee tus ntawm lawv tau pleev xim thiab txheej yas, thiab, txawm tias tseem siv niaj hnub no, lawv ob leeg muaj qhov tsis zoo: lawv yog ib ntus thiab tsis ntseeg. Thaum cov khoom hlau puas lawm, nws cov seem tsim xeb, thaum txheej yas yuav poob thiab ua rau muaj kev puas tsuaj ntxiv. Yog li ntawd, ob qho tib si tha xim thiab txheej yas xav tau kev saib xyuas txuas ntxiv.
Cov txiaj ntsig ntawm galvanization
Galvanization tau dhau los ua txoj kev tiv thaiv hlau nrov vim muaj ntau yam txiaj ntsig nws tuav.
Ua ntej tshaj plaws, thaum nws los txog rau cov nqi, galvanization yog qis dua tus nqi ntawm stainless. Nyob rau lub sijhawm ntev, nws yuav tsum tau saib xyuas tsawg dua thiab ua kom lub neej ntev ntawm cov khoom siv galvanized.
Thib ob, thaum nws los txog rau kev ua tau zoo, galvanization muab cov txheej txheem txhim khu kev qha thiab ua haujlwm zoo rau huab cua thiab kev puas tsuaj. Qhov no ua tiav yam tsis muaj kev cuam tshuam rau lub hauv paus hlau zoo lossis kev ua haujlwm.
Thib peb, galvanization yog tib txoj kev uas tiv thaiv cov ntu me me ntawm cov hlau raug los ntawm kev puas tsuaj.
Thiab, kawg tab sis tsis kawg, nrog galvanization, tsis muaj sij hawm poob rau hauv kev npaj saum npoo, tshuaj xyuas thiab pleev xim, tsis zoo li tha xim thiab txheej txheej yas, uas yuav tsum tau npaj tshwj xeeb saum npoo ua ntej kev tiv thaiv txheej txheem.
Tag nrho cov no ua rau galvanization yog qhov kev xaiv zoo tshaj plaws rau kev tiv thaiv ib qho khoom siv hlau los ntawm kev cuam tshuam rau cov khoom thiab kev puas tsuaj, uas yog qhov tseem ceeb tshwj xeeb hauv cov khoom ntim khoom pov tseg.
Galvanization drawbacks
Galvanization ua haujlwm zoo kawg nkaus nrog cov khoom uas yuav tsum tsis muaj kev saib xyuas tshwj xeeb, xws li cov thawv ntim khoom pov tseg, lossis qhov ntawd yuav tsum tiv taus kev ntxhov siab. Tsis tas li ntawd, kev sib cuag ntawm cov khoom noj uas muaj galvanized cookware lossis cov khoom siv hauv chav ua noj yog tsis pom zoo, vim nws tuaj yeem ua rau zinc lom thiab zaub mov tsis zoo.
Yog li ntawd, kev khaws cia lossis npaj zaub mov hauv cov khoom siv hlau thiab cov khoom siv galvanized yuav tsum zam txhua tus nqi. Namely, nyob rau hauv cov khoom noj uas nplua nuj nitrate, xws li cov nqaij kho, cov nqaij haus luam yeeb, nqaij npua thiab cov hnyuv ntxwm siav, uas nitrate siv rau kev khaws cia nrog rau ntsev, kev sib cuag nrog cov hlau galvanized tsim cov tshuaj tiv thaiv ntawm kev tso zinc thiab ua rau oxidization, yog li corrosion. . Qee cov txiv hmab txiv ntoo tshiab muaj cov sulfur dioxide uas khaws cia ntev dua tab sis ua rau tib qho kev sib cuag nrog hlau.
Txhawm rau tiv thaiv qee qhov xwm txheej ntawm cov tshuaj tiv thaiv, tsis yog cov zaub mov nyoos yuav tsum tau ntsib nrog galvanized cookware lossis cov tais diav.
