Galvanized hlau yog dab tsi?

GNEE Steel Galvanized Sheet Hlau Rolls

Yog tias koj tshiab rau lub ntiaj teb ntawm cov khoom siv hlau thiab hlau, tej zaum koj yuav tau hnov ​​lo lusgalvanizepov ib ncig ob peb zaug. Tab sis dab tsi yog galvanized? Tampa Steel thiab Supply nyob ntawm no los muab txhua yam ntaub ntawv koj xav tau kom nkag siab txog kev siv galvanizing, nws siv, thiab nws cov txiaj ntsig.

Galvanized txhais li cas?

Galvanizing yog txheej txheem ntawm kev siv cov txheej txheem tiv thaiv hlau los yog hlau. Cov txheej yog tsim los ntawm zinc thiab yog siv los tiv thaiv kev tsim ntawm xeb. Galvanization yog qhov tseem ceeb vim nws muab kev tiv thaiv ntev rau cov khoom hlau thiab hlau.

Galvanization tiv thaiv lub hauv paus hlau hauv qab li cas?

1. Cov zinc txheej tiv thaiv corrosive yam xws li acid(piv txwv li acid los nag) los ntawm ncav cuag cov hlau hauv qab.

2. Galvanization tiv thaiv los ntawm xeb.Thaum cov txheej yog khawb, zinc tseem yuav "tshem nws cov anode" yooj yim dua li lub hauv paus hlau ua - uas tiv thaiv nws los ntawm xeb.

3. Cov zinc tiv thaiv cov hlau los ntawm corroding sai dua li lub hauv paus hlau.Qee zaum cov khoom siv tshwj xeeb hu ua "chromate" yog ntxiv rau cov hlau galvanized, qhov no ua rau nws corrode sai dua. Tej zaum nws yuav zoo li qhov ntawd tsis yog qhov koj xav tau, tab sis nco ntsoov cov zinc corroding ua ntej cov hlau yog dab tsi tiv thaiv cov hlau hauv qab los ntawm xeb.

 

Koj tuaj yeem qhia tau tias thaum twg hlau yog galvanized vim tias zinc ua ib qho txawv ntawm cov hlau hu ua "spangle."

Lo Lus "Galvanize" Los Ntawm Qhov Twg?

Lo lus "galvanization" los ntawm lub npe ntawm Italian kws tshawb fawb Luigi Galvani. Niaj hnub no, "galvanize" feem ntau yog hais txog cov txheej txheem ntawm txheej txheej hlau nrog zinc, tab sis nws tau siv los ua ib lo lus uas tau piav qhia "muab hluav taws xob shocks".

Luigi Galvani tau kawm "bioelectricity", lossis yuav ua li cas cov hlab ntsha thiab cov ntaub so ntswg hauv peb lub cev tsim thiab ua rau cov qauv hluav taws xob. Nws xub pom tias lub cev tsim hluav taws xob thaum nws zapped ib tug qav tuag ceg nrog hluav taws xob taws, thiab cov nqaij ntshiv.

Galvanization txheej txheem yog dab tsi?

Muaj ob peb txoj kev ntawm galvanizing hlau. Cov txheej txheem feem ntau yog cov txheej txheem kub-dip galvanization. Txoj kev no ntawm galvanization tsim ib tug zoo, tuab txheej ntawm zinc nyob rau sab saum toj ntawm lub hauv paus hlau - uas ua rau nws ntxiv resistant rau corrosion. Rau feem ntau, cov txheej txheem kub-dipping tsis txi cov txheej txheem kev ncaj ncees ntawm cov hlau, tab sis qee qhov heev.siab zogsteel tuaj yeem raug kev txom nyem los ntawm hydrogen embrittlement.

Cov hlau siv nyob rau hauv lub tsheb lub cev kuj yog galvanized, tab sis vim hais tias cov khaubncaws sab nraud povtseg ntawm cov xim yuav tsum tau siv tom qab - lawv siv ib tug txawv galvanization txheej txheem. Qhov no yog vim cov zinc txheej los ntawm txoj kev kub-dip yog tuab heev, thiab ua rau muaj teeb meem nrog cov xim adhesion.

Hloov chaw, tsheb siv cov txheej txheem electrogalvanization. Ib qho kev daws ntawm dej ntsev (saline) thiab zinc yog muab tso rau hauv lub tank, thiab cov hlau los yog lub hauv paus hlau yog dipped rau hauv. Ib qho hluav taws xob tam sim no khiav los ntawm lub vat, thiab zinc bonds rau lub hauv paus hlau!

Ib daim ntawv tshwj xeeb ntawm galvanizing, hu ua Sherardizing, yog siv los tsim cov zinc txheej ntawm cov khoom hlau lossis tooj liab. Nws tau tsim los ntawm metallurgist Sherard Osborn Cooper-Coles thiab patented nyob ib ncig ntawm 1900.

Cov khoom siv hlau uas yuav tsum tau galvanized yog muab tso rau hauv lub kaw, tig lub nruas nrog rau zinc hmoov, thiab qee zaum muaj cov muab tub lim zoo li cov xuab zeb. Tom qab ntawd lub nruas yog superheated rau 500C. Ntawm qhov kub siab tshaj 300C, zinc hloov mus rau hauv vapor - thiab vapor nkag mus rau cov hlau tig sab hauv ntawm lub nruas.

Cov txheej txheem no tseem hu ua "dry galvanizing" vim tias tsis muaj cov kua dej siv.

Qhov no tej zaum yuav muaj pes tsawg qhov me me nyob ib puag ncig koj lub tsev, xws li cov ntsia hlau lossis cov txiv ntseej thiab bolts, tau galvanized. Cov txheej txheem no tsis siv cov hydrogen, yog li hydrogen embrittlement tsis tuaj yeem tshwm sim thaum lub sijhawm no ntawm galvanizing.

5 Cov txiaj ntsig ntawm Galvanizing Hlau

Yog tias koj tab tom nrhiav yuav steel rau koj qhov project tom ntej, xav txog kev xaivgalvanized hlau. Galvanized steel touts ntau cov txiaj ntsig ntsuas tau, suav nrog cov hauv qab no:

1. Kev lag luam:Xaiv galvanized steel thawj zaug yuav zoo li kim dua, tab sis nws yog ib qho kev nqis peev zoo rau lub sijhawm ntev. Ntxiv mus, galvanizing yog tiag tiag pheej yig dua li ntau lwm cov hlau tiv thaiv txheej.
2. Kev kho qis:Hlau uas tsis muaj txheej txheej tiv thaiv yuav tsum tau saib xyuas ntau dua los kho qhov tsos thiab kev nyab xeeb ntawm cov khoom.
3. Ntev ntev:Galvanized steel coatings tuaj yeem muaj lub neej ntev txog li 50 xyoo thiab tuaj yeem tiv taus hauv nroog thiab ntug hiav txwv.
4. Kev tiv thaiv tsis sib xws:Txhua nti ntawm cov hlau galvanized yog tiv thaiv-qhov no suav nrog cov npoo ntse thiab cov tawv tawv kom ncav cuag crevices.
5. Ceev:Cov txheej txheem ntawm galvanizing yog ceev thiab yooj yim. Qhov tseeb, lub tsho tiv thaiv tag nrho tuaj yeem siv rau hauv ob peb feeb xwb.

Koj tuaj yeem siv galvanized hlau li cas?

Galvanized hlau yog siv txhua qhov chaw!

Lub cev ntawm lub tsheb thiab ntau lub tsheb kauj vab yog tsim los ntawm cov hlau galvanized. Qee cov kav dej haus tseem ua los ntawm cov hlau galvanized.Cov ntawv txias txiashlau kuj nquag galvanized.

Cov txiv ntseej, bolts, cov cuab yeej, thiab cov xov hlau ntawm txhua yam tam sim no yog galvanized vim nws yog cov txheej txheem pheej yig, thiab yeej pab txhawb cov hlau txoj sia!

Galvanized steel, tshwj xeeb tshaj yog, feem ntau yog siv nyob rau hauv niaj hnub "steel thav duab" vaj tse. Galvanized steel kuj tseem siv los tsim cov qauv xws li balconies, verandahs, staircases, ladders, taug kev, thiab lwm yam.

Galvanized hlau yog ib qho kev xaiv zoo yog tias koj qhov project yuav nyob sab nraud tom qab nws ua tiav. Cov laj kab, ru tsev, thiab kev taug kev sab nraum zoov yog txhua qhov kev xaiv zoo rau cov hlau galvanized!
