1.}} Yuav ua li cas xaiv cov khoom ntawm round pas nrig raws li kev kawm ntawm ib puag ncig corrosion?
Cov txheej txheem atmospher no: cov txheej galvanized tuaj yeem ua tau los ntawm kev tiv thaiv corrosion (xws li lub ntsej muag muaj zog) lossis 304)
Muaj zog corrosive: Seaterwater / ntsev tshuaj txau: 316 Stainless hlau (tiv taus mo, tiv taus chloride ion corrosion);
Acid thiab alkali media: 316 Stainless hlau (kua qaub tsis kam) lossis teflon-coated galvanized ntu (ntau heev tshaj plaws scenarios).
2.}} Yuav ua li cas xaiv cov khoom ntawm galvanized round round pas nrig raws li kev yoog raws li kev siv tshuab?
Cov vuam siv vuam: Xaiv Q235 (tsis tu ncua w235 (tsis txhob muaj 45 tus hlau (xav tau preheating kom tiv thaiv kev tawg).
Yuav Tsum Tau Kev Kho Cua sov: Rau Quenching thiab Xaiv 45 # steel lossis 20crmnti (Tempering tuaj yeem txhim kho los ntawm kev kho mob (304/316) Feem ntau tsis kub {}}
Txias kev tsim: 304 stainless hlau muaj cov zoo huv thiab yog qhov haum rau khoov thiab stamping (xws li cov tais diav hauv chav ua noj); Q235 yog ob, thiab Q345 yog qhov nyuaj me ntsis rau cov ntawv txias .
3. Yuav ua li cas yog lub galvanized hloov bar cov ntaub ntawv nrog tus nqi siab thiab kev ua tau zoo piv?
Tsawg-Nqi Teeb Meem: Q235, Q235, Q345, Haum rau kev tsim kho thiab cov tshuab feem ntau.
Nruab nrab- thiab siab-nqi scenarios: 45 # steel, 20cmnti, siv rau cov khoom siv tshuab {}}
Cov Hlau Loj: 304 stainless hlau, 316 stainless hlau, tsuas yog siv nyob rau hauv cov xwm txheej nrog rigid corrosion tsis kam rau.
4. Dab tsi yog cov kev siv cov xwm txheej ntawm Galvanized nruab nrab ntawm cov chaw tsim khoom lag luam?
Cov xwm txheej: Scaffolding, Tus Qauv Hlau Txhawb
Yuav tsum muaj: lub nra zoo li qub, ib puag ncig sab nraum zoov, vuam teeb hluav taws xob yuav tsum tau ua
Cov Khoom Siv Kom Zoo: Q235 Galvanized Round Bar
Vim li cas: Muaj zog nruab nrab (tawm los 235mpa), txheej malvanized, galvanized txheej yog resensive rau atmospheric corrosion, thiab tus nqi qis .
5.}}}} Yuav ua li cas xaiv Galvanized Qws Khoom Rau choj thiab Cov Ntawv Uas Hnyav?
Scenario: Choj Cables, crane booms • Xav tau: kev tawm tsam siab, kev tawm tsam ntev ntev sab nraum zoov
Cov Khoom Siv Kom Zoo: Q345B Galvanized Round Bar (Tsawg Alloy Kas Lub Zog Hlau)
Vim li cas: Tawm lub zog loj dua los yog sib npaug ntawm 345mpa (40% ntau dua Q235)
