Yuav Ua Li Cas Galvanized Steel Coil yog Tsim - Cov txheej txheem tsim khoom
Galvanized steel coils yog cov khoom siv hlau uas tau kho nrog cov txheej txheem tiv thaiv kom tsis txhob xeb. Cov txheej txheem feem ntau yog zinc, uas ua rau muaj kev cuam tshuam ntawm cov hlau substrate thiab corrosive ib puag ncig. Cov txheej txheem no tsis tsuas yog txhim kho lub neej ntawm cov hlau, tab sis kuj ua rau nws zoo nkauj zoo nkauj.
Cheebtsam ntawm galvanized steel coils
Lub ntsiab tivthaiv ntawm galvanized steel coils yog, ntawm chav kawm, steel. Txawm li cas los xij, qhov kev txiav txim siab yog cov zinc txheej uas encapsulates steel substrate. Cov txheej zinc no ua raws li kev cuam tshuam kev txi, uas corrodes es tsis txhob ntawm cov hlau thaum nws raug rau cov ntsiab lus corrosive. Tsis tas li ntawd, lub thickness ntawm zinc txheej yuav txawv, yog li cuam tshuam rau qib ntawm kev tiv thaiv corrosion muab.
Kev tsim khoom:
1. Kev Npaj Nto:
Tag nrho cov lus pib nrog kev npaj ntawm cov hlau substrate. Cov txheej txheem steel hlau tau dhau los ua cov txheej txheem tu kom huv si kom tshem tawm cov kab mob ntawm qhov chaw xws li xeb, roj lossis av. Qhov kev npaj no ua kom zoo tshaj plaws adhesion ntawm galvanized txheej thov nyob rau hauv cov kauj ruam tom ntej.
2. Galvanizing da dej:
Tom qab ntxuav, cov hlau kauj yog muab tso rau hauv ib lub molten zinc da dej. Cov kauj ruam no yog hu ua kub dip galvanizing thiab yog tus yuam sij rau cov txheej txheem. Zinc da dej yog khaws cia ntawm qhov kub thiab txias kom ntseeg tau tias muaj kev sib raug zoo ntawm cov zinc thiab cov hlau. Qhov no metallurgical daim ntawv cog lus txhim kho lub durability thiab ntev lub neej ntawm lub resulting galvanized hlau.
3. Alloying thiab Solidification:
Thaum cov hlau coil raug tshem tawm ntawm lub da dej galvanizing, ntau tshaj molten zinc drips tawm, tawm hauv ib txheej ntawm zinc adhering rau saum npoo ntawm cov hlau. Nyob rau theem no, alloying ntawm zinc thiab hlau yuav tshwm sim, ntxiv txhim khu kev sib raug zoo ntawm ob cov ntaub ntawv. Cov zinc txheej solidifies ntawm cov hlau substrate los tsim cov txheej tiv thaiv.
4. Txias thiab tshuaj xyuas:
Lub galvanized steel kauj yog tom qab ntawd txias kom cia cov zinc txheej kom tag nrho solidify thiab khi rau cov hlau. Tom qab txias, cov coils raug tshuaj xyuas kom zoo los xyuas kom meej qhov sib xws ntawm txheej txheej thiab nws cov adhesion rau cov hlau. Kev tshuaj xyuas no yog qhov tseem ceeb los xyuas kom meej tias cov khoom kawg ua tau raws li cov qauv tsim nyog.
5. Kev kho mob tom qab (yeem):
Nyob ntawm daim ntawv thov thiab cov khoom xav tau, galvanized steel coils yuav raug kho ntxiv. Ib qho kev kho tom qab kev kho mob yog passivation, uas yuav tsum tau siv cov tshuaj tov rau zinc txheej los txhim kho nws cov corrosion kuj. Tsis tas li ntawd, topcoats tuaj yeem siv rau lub hom phiaj zoo nkauj lossis muab kev tiv thaiv ntxiv tiv thaiv ib puag ncig tshwj xeeb.
Galvanized steel coil ntau lawm yog muab cov hlau phaj rau hauv lub lauj kaub fusible zinc thiab coated zinc rau ntawm nws qhov chaw.
Nruam galvanizing yog nws cov txheej txheem ntau lawm. Nws hais txog kev muab cov av steel rau hauv lub lauj kaub fusible zinc.
Alloy galvanized steel panels kuj yog ua los ntawm kub-dip galvanizing. Tab sis thaum nws tawm ntawm lub lauj kaub zinc, qhov kub tau nce mus rau 500 degrees, thiab cov yeeb yaj kiab alloy yog tsim.
Nws muaj qhov zoo ntawm adhesion thiab weldability.
Peb tuaj yeem tsim cov ntawv galvanized, cov ntawv galvalume, cov ntawv xim-coated, xim-coated aluminium coils thiab cov ntawv corrugated.
tos ntsoov rau peb kev koom tes.
