Cov ntaub ntawv hauv paus ntawm galvanized carbon steel yeeb nkab thiab dub carbon steel yeeb nkab yog tib yam, ob qho tib si yog Q195 / Q215 / Q235 / Q355 thiab lwm yam carbon steel qauv. Cov khoom siv kho tshuab yog txiav txim siab los ntawm qib khoom siv hauv paus. Qhov sib txawv tseem ceeb nyob hauv cov txheej txheem kho saum npoo, uas ua rau muaj kev cuam tshuam rau kev tiv thaiv- kev ua haujlwm corrosion thiab cov xwm txheej siv tau. Cov hauv qab no yog cov ntsiab lus tseem ceeb:
Cov txheej txheem tseem ceeb sib txawv
Dub carbon steel yeeb nkab: Tsis muaj kev tshwj xeeb los tiv thaiv- kev kho corrosion. Thawj xim ntawm cov yeeb nkab thaum lub sij hawm tsim khoom yog khaws cia. Kub- cov kav dej dov tshwm tsaus xim av nrog cov hlau oxide nplai ( ntxhib), thaum txias - cov kav dej yog cov nyiaj - grey (kuj sib npaug). Qee qhov tsuas yog ua rau cov roj yooj yim thiab xeb tshem tawm.
Galvanized carbon steel yeeb nkab: Cov khoom siv hauv paus yog cov yeeb nkab dub. Tom qab cov kua qaub ntxuav kom tshem tawm cov xeb, nws dhau los ua kub -dip galvanization (txoj kev tseem ceeb, nrog txheej txheej ntawm 60-100 μm, muaj zog adhesion) lossis electro-galvanization (rau nyias-walled kav, nrog txheej txheej ntawm 10-30 μm, ib txheej ci ci rau kev tiv thaiv corrosion).
Qhov sib txawv ntawm cov khoom siv
Dub carbon steel yeeb nkab: Haum rau qhuav thiab tsis yog - ib puag ncig corrosive, los yog rau cov xwm txheej uas nws tus kheej tom ntej - tiv thaiv - kev kho corrosion yuav tsum tau, xws li cov kav dej thiab cov pa ib ntus hauv cov kav dej hauv tsev, ua ntej - txhim kho cov kav dej, cov khoom siv hauv paus, thiab cov kav dej ib ntus.
Galvanized carbon steel yeeb nkab: Tsim nyog rau corrosive ib puag ncig xws li ntub dej, sab nraum zoov, thiab hauv av, xws li cov dej hauv tsev thiab kev tso dej, cov kav dej sab nraum zoov hauv nroog, cov kav dej tsis tshua muaj siab, kev txhawb nqa sab nraum zoov, thiab cov kav dej ua liaj ua teb. Nws lub neej kev pabcuam yog 3-5 npaug ntawm cov kav dej dub nyob rau hauv ib txwm muaj.
Kev sib piv ntawm Core Strengths thiab Weaknesses
Dub carbon steel yeeb nkab: Cov txiaj ntsig zoo suav nrog tus nqi qis (30% -50% qis dua cov kav dej galvanized ntawm tib lub ntsiab lus), kev ua haujlwm yooj yim (tuaj yeem ncaj qha welded yam tsis muaj kev cuam tshuam los ntawm zinc txheej), thiab lub sijhawm luv luv; Qhov tsis zoo yog tsis muaj kev tiv thaiv corrosion, nws yooj yim rau xeb, thiab cov nqi kho mob siab.
Galvanized carbon steel yeeb nkab: Qhov zoo muaj xws li kev tiv thaiv corrosion zoo heev, tsis xav tau kev saib xyuas thawj zaug, thiab ntxuav cov phab ntsa sab hauv thiab sab nrauv; Qhov tsis zoo yog tus nqi siab, thiab vuam yuav tsum tau xuab zeb tawm ntawm zinc txheej. Nws tsis haum rau siab - kub (＞ 200 degree) thiab ib puag ncig corrosive heev.
Quick Differentiation Methods
Cov tsos mob: Cov kav dej dub muaj xim av tsaus / grey nrog oxide txheej / xeb me ntsis; cov kav dej galvanized yog uniformly silver grey (kub-dip) lossis ci nyiaj (electroplated), nrog zinc flakes thiab tsis muaj xeb.
2. Polishing: Tom qab sib tsoo, cov yeeb nkab dub tsuas pom cov nyiaj - grey xim hlau; rau cov yeeb nkab galvanized, lub ci dawb zinc txheej raug nthuav tawm ua ntej, ua raws li cov pa roj carbon steel hauv qab.
3. Kev Taw Qhia: Cov kav dej Galvanized tau cim nrog "Kub Dip / Galvanizing" thiab txheej txheej, thaum cov kav dej dub tsuas yog sau nrog cov khoom, qhov loj me, thiab lub npe khoom.
Cov lus qhia xaiv cov khoom siv
Kev siv nyiaj tsawg, ib puag ncig qhuav lossis xav tau kev ua haujlwm ntxiv yuav tsum muaj cov kav dej dub; rau sab nraum zoov, ntub dej, hauv av thiab dej / qhov dej ntws tawm, kub -dip galvanized kav yuav tsum tau xaiv; rau kev teeb pom kev teeb pom kev zoo, electro-galvanized kav tuaj yeem xaiv.
