Muaj pes tsawg hom ntawv galvanized tuaj yeem faib ua pawg raws li cov txheej txheem tsim khoom thiab ua tiav?

Cov ntawv galvanizedtuaj yeem muab faib ua pawg hauv qab no raws li kev tsim khoom thiab kev ua tiav:

(1)Kub dipped galvanized hlau ntawv. Cov ntawv hlau nyias nyias raug muab tso rau hauv lub dab dej zinc uas yaj kom ua ib daim ntawv hlau nyias nyias nrog ib txheej zinc lo rau ntawm nws qhov chaw. Tam sim no, kev siv tseem ceeb ntawm kev tsim cov txheej txheem galvanizing tas mus li, uas yog, cov yob hlau txuas ntxiv raug muab tso rau hauv lub dab dej zinc plating uas ua los ntawm cov hlau galvanized;

(2) cov hlau galvanized alloyed. Cov hlau phaj no kuj tsim los ntawm kev kub dipping, tab sis tam sim ntawd tom qab tawm hauv lub tank, nws raug cua sov txog li 500 ℃, yog li nws tsim cov zaj duab xis nyias ntawm zinc thiab hlau alloy. Hom hlau galvanized no muaj cov xim zoo adhesion thiab weldability;

(3) Daim ntawv hlau electro-galvanized. Kev tsim cov ntawv hlau galvanized no 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 hlau ntawv. Ib sab galvanized hlau ntawv, uas yog, galvanized tsuas yog nyob rau ib sab ntawm cov khoom. Nws muaj kev hloov pauv zoo dua li ob sab galvanized ntawv hauv cov nqe lus ntawm kev vuam, pleev xim, tiv thaiv xeb kho thiab ua tiav. Txhawm rau kov yeej qhov tsis zoo ntawm ib sab zinc tsis muaj txheej, muaj lwm hom ntawv galvanized coated nrog ib txheej nyias ntawm zinc nyob rau sab tod, uas yog, ob sab sib txawv galvanized ntawv;

(5) Cov hlau galvanized hlau sib xyaw thiab sib xyaw. Nws yog ua los ntawm zinc thiab lwm yam hlau xws li txhuas, txhuas txhuas, zinc thiab lwm yam hlau sib xyaw thiab txawm tias cov hlau sib xyaw plated. Hom hlau phaj no muaj kev ua tau zoo heev tiv taus xeb thiab kev ua tau zoo pleev xim;

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

Qhov tsos ntawm cov hlau galvanized
[1] Qhov chaw nto:Phaj GalvanizedVim yog cov txheej txheem txheej txheem hauv kev kho mob ntawm ntau txoj kev sib txawv, qhov xwm txheej ntawm qhov chaw sib txawv, xws li paj zinc ib txwm muaj, paj zinc zoo, paj zinc tiaj tus, paj zinc tsis muaj, thiab kev kho phosphate ntawm qhov chaw thiab lwm yam. Tus qauv German kuj qhia txog qib ntawm qhov chaw.
[2] Cov ntawv galvanized yuav tsum muaj qhov zoo nkauj, yuav tsum tsis muaj qhov tsis zoo uas ua rau siv cov khoom tsis zoo, xws li tsis muaj plating, qhov, tawg, thiab slag, ntau dua qhov tuab ntawm plating, abrasion, chromic acid stains, dawb xeb, thiab lwm yam.

① Feem ntau hais lus, tsuas yog cov ntawv galvanized uas muaj cov qauv, tensile thiab cov ntawv galvanized uas kos tob xwb thiaj li yuav tsum muaj cov yam ntxwv tensile. Cov ntawv galvanized uas muaj cov qauv yuav tsum muaj qhov taw tes tawm, lub zog tensile thiab elongation, thiab lwm yam; tensile tsuas yog xav tau elongation xwb. Cov nqi tshwj xeeb saib "8" hauv ntu no ntawm cov qauv khoom cuam tshuam;
② txoj kev xeem: zoo ib yam li txoj kev xeem hlau nyias dav dav, saib "8" uas muab los ntawm cov qauv cuam tshuam thiab "daim ntawv hlau carbon ib txwm muaj" teev nyob rau hauv tus qauv txoj kev xeem.

[2] Kev sim khoov:
Kev ntsuam xyuas khoov yog qhov project tseem ceeb los ntsuas qhov ua tau zoo ntawm cov hlau ntawv, tab sis cov qauv hauv tebchaws ntawm ntau yam kev cai ntawm cov hlau ntawv galvanized tsis sib xws, tus qauv hauv Tebchaws Meskas, ntxiv rau qib qauv, lwm tus tsis tas yuav tsum tau kuaj khoov thiab tensile. Nyiv, ntxiv rau qib qauv, kev tsim cov ntawv corrugated thiab cov ntawv corrugated dav dav lwm yam tsis yog qhov seem yuav tsum tau ua qhov kev ntsuam xyuas khoov.

Kev tiv thaiv corrosion ntawm galvanized ntawv muaj ob lub ntsiab nta:

1, lub luag haujlwm ntawm cov txheej tiv thaiv
Nyob rau hauv qhov chaw galvanized los tsim ib zaj duab xis oxide ntom ntom

2, thaum qee qhov laj thawj khawb hauv zinc txheej, zinc ib puag ncig siv ua cation los tiv thaiv kev xeb ntawm hlau.
