Kev faib tawm thiab qhov sib txawv ntawm cov kav dej Galvanized

Tianjin Lefin Industrial Co., Ltd yog ib qho ntawm cov tuam txhab kev paub ntau tshaj plaws thiab cov neeg muag khoom ntawm kev faib tawm thiab qhov sib txawv ntawm cov kav dej galvanized hauv Suav teb. Thov koj xav tias dawb mus yuav cov kev faib tawm zoo thiab qhov sib txawv ntawm cov kav dej galvanized los ntawm peb lub hoobkas. Kev pabcuam zoo thiab tus nqi tsim nyog muaj.

Raws li cov txheej txheem galvanizing thiab ntau lawm ntws, cov kav dej loj galvanized hauv khw tuaj yeem muab faib ua peb pawg:

1. Kub-Dip Galvanized Pipes (Kub-Dip Galvanized, HDG): Cov kav dej tiav yog kub -dip galvanized tag nrho. Lawv yog cov feem ntau siv los tiv thaiv - cov kav dej xeb hauv engineering.
2. Electro-Galvanized Pipes (Txias-Dip Galvanized, EG): Lub zinc txheej yog tso los ntawm electrolysis rau sab nrauv ntawm cov yeeb nkab. Lawv yog nyias- cov khoom siv galvanized nrog lub teeb los tiv thaiv- corrosion khoom.
3. Ua ntej-galvanized Pipes (Galvanized Sawb Pipes/Steel Sawb Galvanized Pipes, Ua ntej-galvanized):Lawv yog welded los ntawm pre-galvanized steel strips. Lawv kuj tseem hu ua "txias strip galvanized kav".

Ob qho no yog cov txheej txheem galvanizing txawv kiag li, nrog rau qhov sib txawv tseem ceeb xws li lub hauv paus ntsiab lus mus rau kev ua haujlwm.

1. Qhov tseem ceeb sib txawv hauv cov txheej txheem

• Kub-galvanized kav:Cov kav dej uas twb tau tsim lawm (welded kav / seamless kav) yog cov kua qaub- ntxuav thiab kho nrog auxiliary plating ua ntej muab tso rau hauv molten zinc ntawm 440-460℃. Los ntawm cov tshuaj tiv thaiv metallurgical, zinc- hlau alloy txheej + ntshiab zinc txheej txheej txheej yog tsim rau saum npoo ntawm cov yeeb nkab, uas yog kev sib xyaw ua ke ntawm qhov kub thiab txias. Cov phab ntsa sab hauv thiab sab nrauv, nrog rau cov hlua khi, tuaj yeem ua tiav nrog zinc txheej.
• Electro-galvanized Pipes (Cold-galvanized):Nyob rau hauv chav tsev kub, zinc ions tau tso rau sab nrauv ntawm cov yeeb nkab los ntawm txoj cai electrolysis, tsim tsuas yog ib txheej zinc ntshiab xwb. Nws yog qhov qis -kub lub cev adhesion. Sab hauv phab ntsa ntawm cov yeeb nkab tsis tuaj yeem coated nrog zinc, thiab weld seam yog qhov ua tsis tiav txheej.

2. Kev ua tau zoo thiab lub neej sib txawv

• Adhesion: Kub-galvanized yog metallurgical ua ke, thiab cov zinc txheej yog sib xyaw nrog cov yeeb nkab hauv paus, ua rau nws tsis tshua tev tawm txawm tias nyob rau hauv kev khoov, cuam tshuam, lossis kev sib tsoo; electro-galvanized yog electrostatic adsorption, nrog tsis muaj zog adhesion, thiab khawb me ntsis yuav ua rau zinc txheej tev tawm.

• Anti-corrosion Peev xwm: Kub-galvanized muaj ob qho tib si lub cev barrier + sacrificial anode cathodic tiv thaiv, thiab nws anti-corrosion muaj peev xwm yog 5-10 npaug ntawm electro-galvanized.

①INdoor Dry Environment:Kub-galvanized muaj lub neej ntev ntawm 30-50 xyoo, thaum electro-galvanized kav 8-15 xyoo
②Sab nraum zoov ib puag ncig: Kub-galvanized kav 15-25 xyoo, thaum electro-galvanized kav 2-5 xyoos
③Ntug hiav txwv / Hiav Txwv / faus: Kub-galvanized kav 15-30 xyoo, thaum electro-galvanized kav 0.5-2 xyoos. Nws feem ntau tsis pom zoo siv

• Ntsej Tsuag Test: Kub-galvanized tuaj yeem dhau 240-1000 xuab moos ntawm cov tshuaj tsw qab ntsev tsis muaj xeb; electro-galvanized feem ntau qhia xeb tom qab 48-100 teev.

3. Cov yam ntxwv thiab kev ua haujlwm zoo

• Kub-galvanized: Qhov saum npoo yog matte silver- grey, nrog qee cov zinc flakes thiab pob, thiab qhov kev ntxhib los mos yog ntxhib; zinc txheej yog nquag volatilization thiab tsim zinc pa luam yeeb thaum vuam.
• Hluav taws xob-galvanized: Qhov saum npoo yog du thiab ci, nrog rau qhov zoo nkauj dua; welding yog ib qho yooj yim, tab sis cov txheej yog yooj yim rau cov npuas tsim ntawm qhov kub thiab txias.

4. Daim ntawv thov Scenarios

• Kub-galvanized kav: Kev siv dej hauv nroog thiab kev tso dej, cov kav dej tiv thaiv hluav taws, kev ua haujlwm sab nraum zoov, faus thaiv, kev txhawb nqa photovoltaic, cov phiaj xwm ntug dej hiav txwv, cov ncej thaiv, thiab lwm yam, uas yuav tsum muaj kev tiv thaiv siab - corrosion, yog cov kev xaiv tseem ceeb hauv kev tsim kho.
• Electro-Cov kav dej galvanized: Tsuas yog tsim nyog rau qhov chaw qhuav hauv tsev, xws li cov kav hlau txuas hluav taws xob, cov khoom siv kho kom zoo nkauj sab hauv tsev, cov khoom siv rooj tog yeeb nkab, thiab lwm yam. Hauv Tuam Tshoj, txias- cov kav dej galvanized tau raug txwv tsis pub siv los ua cov kav dej.

1. Qhov txawv ntawm Core:Nws yog cov txheej txheem ntawm cov txheej txheem, tsis yog cov khoom siv raw khoom

Cov ntaub ntawv hauv paus ntawm ob qho tib si yog cov pa roj carbon zoo tib yam. Qhov sib txawv tseem ceeb yog qhov sib lawv liag ntawm cov txheej txheem galvanizing, tsis yog cov khoom sib txawv ntawm cov khoom siv raw:

• Kub-dip galvanized yeeb nkab: Ua ntej, cov pa roj carbon steel yog welded rau hauv cov yeeb nkab tiav, thiab tom qab ntawd tag nrho cov yeeb nkab yog muab tso rau hauv zinc da dej kom tiav cov galvanization (post- txheej txheem galvanization).
• Ua ntej-galvanized yeeb nkab(galvanized sawb yeeb nkab): Ua ntej, cov pa roj carbon steel sawb (cov ntaub ntawv cov ntaub ntawv) yog kub tsis tu ncua -dip galvanized ntawm lub zeb zeb kom tau galvanized sawb hlau, thiab ces cov galvanized sawb hlau yog welded rau hauv cov yeeb nkab (galvanization ua ntej, ces cov yeeb nkab raug).

Hauv cov ntsiab lus yooj yim: Ib qho yog "ua cov yeeb nkab ua ntej thiab tom qab ntawd galvanize nws", thiab lwm yam yog "galvanize zinc zoo ua ntej ua cov yeeb nkab".

2. Kev ua tau zoo thiab daim ntawv thov sib txawv hauv qhov chaw sib txawv

• Anti-corrosion lub neej:Kev tiv thaiv -corrosion lub neej ntawm kub-dip galvanized yeeb nkab yog 35 npaug ntawm pre-galvanized yeeb nkab. Ua ntej- cov kav dej galvanized feem ntau pib xeb ntawm cov welds tom qab 25 xyoo nyob rau hauv ib puag ncig sab nraum zoov, thaum kub -dip galvanized tuaj yeem siv ruaj khov rau ntau tshaj 15 xyoo.
• Cov tsos thiab specifications: Ua ntej- cov kav dej galvanized muaj qhov smoother thiab ci dua, qhov tseeb dua qhov tseeb, thiab feem ntau nyias nyias- cov kav dej me me; kub-dip galvanized kav dej muaj qhov rougher nto, thiab txoj kab uas hla loj dua thiab cov phab ntsa tuab yog ua tiav ntau dua.
• Nqi thiab efficiency: Ua ntej- cov kav dej galvanized yog tsim tas li, nrog kev ua haujlwm siab thiab tus nqi qis, thiab tus nqi feem ntau yog 30% mus rau 50% qis dua qhov qub specification kub -dip galvanized kav; kub-dip galvanized kav yog batch ntau lawm, nrog zinc noj loj thiab nqi ntau dua.
• Siv tau scenarios:

①Kub-dip galvanized yeeb nkab: Sab nraum zoov tej yaam num, qis- kev thauj mus los ntawm cov kua (dej, roj), underground nteg, scaffolding, load-cov kab nrib pleb, thiab lwm yam., siab -thov scenarios.

②Pre-galvanized yeeb nkab: Sab hauv tsev teeb pom kev zoo, vaj tsev cog khoom vaj tse, guardrails, rooj tog kav, hluav taws xob thaiv, kev tsim kho ib ntus, thiab lwm yam., qhuav, qis- corrosion, qis-load scenarios.

• Ua raws sijhawm ntev -lub sij hawm tiv thaiv- corrosion, sab nraum zoov / mounted underground / rau kev thauj mus los dej → Xaiv kub -dip galvanized yeeb nkab
• Nyob sab hauv tsev qhuav, zoo nkauj xav tau, siv nyiaj tsawg → tuaj yeem xaiv ua ntej -galvanized yeeb nkab (galvanized sawb yeeb nkab)
• Tsuas yog siv ib ntus xwb, tsis tshua muaj kev tiv thaiv- cov xwm txheej corrosion → tuaj yeem txiav txim siab electro-galvanized yeeb nkab, tab sis tsis pom zoo rau kev thauj mus los sab nraum zoov thiab dej
