Muaj pes tsawg hom ntawm cov ntawv galvanized tuaj yeem raug cais raws li kev tsim khoom thiab kev ua haujlwm?

Galvanized ntawvtuaj yeem muab faib ua pawg hauv qab no raws li kev tsim khoom thiab kev ua haujlwm:

(1)Kub dipped galvanized steel ntawv. Nyias steel ntawv yog immersed nyob rau hauv ib tug molten zinc da dej los ua ib tug nyias steel ntawv nrog ib txheej ntawm zinc adhering rau nws nto. Tam sim no, qhov tseem ceeb ntawm kev siv cov txheej txheem txuas ntxiv galvanizing, uas yog, cov yob ntawm cov hlau tsis tu ncua rau hauv molten zinc plating da dej ua los ntawm galvanized steel;

(2) alloyed galvanized hlau. Cov phaj hlau no kuj yog tsim los ntawm kub dipping, tab sis tam sim ntawd tom qab tawm hauv lub tank, nws yog rhuab mus txog 500 ℃, thiaj li hais tias nws generates ib tug nyias zaj duab xis ntawm zinc thiab hlau alloy. Hom galvanized steel ntawv no muaj cov xim zoo adhesion thiab weldability;

(3) Electro-galvanized steel ntawv. Kev tsim cov ntawv galvanized steel los ntawm txoj kev electroplating muaj kev ua haujlwm zoo. Txawm li cas los xij, cov txheej txheej yog nyias thiab qhov kev tiv thaiv corrosion tsis zoo li cov ntawv kub-dip galvanized;

(4) Ib sab thiab ob sab tsis zoo galvanized steel ntawv. Ib sab galvanized steel ntawv, uas yog, galvanized nkaus xwb ntawm ib sab ntawm cov khoom. Nws muaj qhov hloov tau zoo dua li ob sab galvanized ntawv nyob rau hauv cov nqe lus ntawm vuam, pleev xim, kev kho xeb thiab kev ua haujlwm. Txhawm rau kom kov yeej qhov tsis txaus ntawm ib leeg-ib sab tsis muaj zinc, muaj lwm hom galvanized ntawv coated nrog ib txheej nyias ntawm zinc ntawm sab nraud, uas yog, ob sab sib txawv galvanized ntawv;

(5) Alloy thiab composite galvanized steel ntawv. Nws yog ua los ntawm zinc thiab lwm yam hlau xws li txhuas, txhuas, zinc thiab lwm yam alloys thiab txawm composite plated hlau. Hom steel phaj no muaj ob qho tib si zoo rustproof kev ua tau zoo thiab kev ua haujlwm zoo;

Ntxiv rau cov saum toj no tsib, kuj tseem muaj xim galvanized steel, luam tawm thiab pleev xim rau galvanized steel, PVC laminated galvanized steel, thiab lwm yam.. Txawm li cas los xij, feem ntau siv tam sim no tseem muaj.Kub Dip Galvanized Phaj.

Cov tsos ntawm galvanized hlau
[1] Surface state:Galvanized phajvim cov txheej txheem txheej hauv kev kho mob ntawm ntau txoj kev, lub xeev saum npoo yog txawv, xws li cov paj zinc zoo tib yam, zoo zinc paj, paj zinc paj, tsis muaj zinc paj, thiab phosphate kho ntawm qhov chaw thiab lwm yam. Tus qauv German kuj tseem qhia txog qib saum npoo.
[2] Galvanized ntawv yuav tsum muaj qhov zoo nkauj, yuav tsum tsis muaj qhov tsis zoo rau kev siv cov khoom, xws li tsis muaj plating, qhov, rupture, thiab slag, ntau tshaj li cov thickness ntawm plating, puas, chromic acid stains, dawb xeb, thiab lwm yam.

① Feem ntau hais lus, tsuas yog cov txheej txheem, tensile thiab sib sib zog nqus-kos duab galvanized ntawv yuav tsum muaj tensile zog. Cov ntawv hlau galvanized yuav tsum muaj qhov taw qhia tawm, lub zog tensile thiab elongation, thiab lwm yam; tensile tsuas xav tau elongation. Cov nqi tshwj xeeb saib "8" hauv ntu no ntawm cov qauv khoom lag luam;
② xeem txoj kev: tib yam li cov qauv nyias nyias, saib "8" muab los ntawm cov qauv tsim nyog thiab "cov pa roj carbon zoo tib yam" uas teev nyob rau hauv cov qauv kev xeem.

[2] Bending Test:
Kev xeem dabtsi yog khoov yog lub luag haujlwm tseem ceeb los ntsuas cov txheej txheem kev ua haujlwm ntawm cov ntawv hlau, tab sis lub teb chaws tus qauv ntawm ntau yam galvanized sheet hlau yuav tsum tsis ua raws, US tus qauv, ntxiv rau cov qauv qib, tus so tsis tas yuav khoov thiab tensile xeem. Nyiv, ntxiv rau cov qauv qib, lub tsev corrugated ntawv thiab cov ntawv corrugated dav dav uas tsis yog tus so yuav tsum tau ua qhov kev sim khoov.

Galvanized ntawv corrosion kuj muaj ob lub ntsiab nta:

1, lub luag haujlwm ntawm kev tiv thaiv txheej
Nyob rau hauv lub galvanized nto los tsim ib tug ntom oxide zaj duab xis

2, thaum muaj qee qhov laj thawj khawb hauv zinc txheej, cov zinc nyob ib puag ncig siv los ua cation los tiv thaiv corrosion ntawm hlau.
