1.What yog qhov tseem ceeb txhais thiab cov txheej txheem ntau lawm ntawm SGCC?
Tub ntxhais nta: SGCC siv cov hlau txias-dov-dov hlau raws li nws substrate. Ib txheej zinc zinc yog tsim nyob rau saum npoo los ntawm cov txheej txheem kub-dip galvanizing (yaum cov hlau hauv Molten Zinc). Cov txheej txheem no ua ke ntawm cov qauv ntawm cov hlau txias-rolled steel nrog corrosion tsis kam ntawm zinc txheej.
Cov Txheej Txheem Ntau Lawm: Txias-Rolled substrate (xws li Spinc Txheej (Zinc Da Dej Tsis Muaj) →
2.What yog cov tsis sib haum thiab kev tawm tsam kev tiv thaiv corrosion ntawm SGCC Zinc Txheej?
Zinc Txheej Txheem hnyav: Cov khoom siv tshwj xeeb yog 60g / m², 80g / m², thiab 180g / m², thiab 18μm, 11.5μm, 11.5μm, 11.5μm, thiab nws tau. Lub thicker lub zinc txheej, qhov muaj zog nws corrosion tsis kam (piv txwv li, cov ntsev txheej sib txig tsis muaj kwv yees li 1.5 zaug ntawm ib qho 60g / m² zinc txheej).
Zinc Txheej Txheej Txheej Txheem: Los ntawm sab nraud hauv, qhov kub-dip galvanized txheej muaj ntawm cov ntshiab zinc txheej (η theem), ib qho zinc-txheej txheej, thiab ib txheej hlau-zinc alloy. Lub alloy txheej yog nruj nreem rau lub substrate thiab tiv taus detachment.
Anti-corrosion txoj cai: txoj kev ua yeeb yam zinc raws li kev tiv thaiv kab mob ua ke, zinc hydroting cov yeeb yaj kiab uas thaiv cov dej thiab cov pa oxygen los ntawm mus txog rau substrate, muab ob qhov kev tiv thaiv dua.
3.Qhov yog cov tshuaj lom neeg muaj pes tsawg leeg thiab cov khoom siv neeg kho mob ntawm SGCC?
Cov khoom siv uas muaj pes tsawg leeg: zoo ib yam li SpCCC, nrog rau 0.15% tsawg dua los yog sib npaug lossis sib npaug lossis sib npaug.
Cov Khoom Siv Neeg Kho Tshuab:
Lub zog tensile: 270-370 MPA
Peple Zog: 130-250 mpa
Txiaj: ntau dua los yog sib npaug rau 20% (zinc txheej me ntsis txo cov khoom siv hauv paus mus elongation, tab sis tseem ua tau raws li kev tsim nyog tsim).
Cov yam ntxwv ua tau: Lub zog yog zoo ib yam li Spcc, nrog me ntsis qis qis dua. Txawm li cas los xij, zinc txheej muab ho zoo dua corrosion tsis kam tshaj li cov hlau liab qab.
4.What yog lub xeev saum npoo thiab kev faib tawm SGCC?
Nto Kho:
Kev sib cais tsis tu ncua: cov me me pom kab muaj kua rau saum npoo, muab ib qho pom tau pom pom ntawm tus nqi qis.
Minimized SPANGLE: Nta Zoo, Cov Khaub Ncaws Zoo, ua rau nws pleev xim lossis Lamination, zam kev sib txawv ntawm cov kab sib txawv.
Spangle-Dawb: Muaj ib tug du, ze li ntawm spangle-dawb, ua rau qhov kev xaiv xaiv tau zoo tshaj plaws uas xav tau cov cuab yeej siv siab (xws li cov cuab yeej siv).
Passivation: Xaiv ntawm Chromate passivation (tsoos corrosion-resistant tab sis muaj cov nkauj chromium (piv txwv li cov ntiv tes dawb (piv txwv li cov ntiv tes ua kom zoo dua.
5. Dab tsi yog cov yam ntxwv ua kom zoo thiab kev thov cov cheeb tsam SGCC?
Cov ntsiab lus zoo:
Zoo tshaj plaws corrosion: piv rau cov hlau liab qab (xws li SpCC), nws lub sijhawm ua haujlwm nyob rau hauv 3-5 zaug.
Cov qauv muaj txiaj ntsig zoo: Tsim nyog rau khoov, stamping, vuam, thiab lwm yam kev kawm (ua siab zoo ntawm lub peev xwm ntawm zinc evaporation thaum vuam).
Nqi Them Nqi: Qhov kub-dip galvanizing cov txheej txheem yog paub tab, nrog tus nqi qis dua electroplating, ua rau haum rau huab hwm coj ntau lawm.
Cov Kev Siv Raug:
Kev tsim kho: Ru tsev panels, phab ntsa phab ntsa, cov hlau nplaum, thiab cov nkhaus (rau cov ntawv thov sab nraum zoov uas yuav tsum muaj huab cua tsis kam).
Cov khoom siv hauv tsev: tub yees rov qab panels, cua txias cov tsev, uas xav tau dej noo thiab corrosion kuj).
Automotive: Cov Cheebtsam Chassis thiab cov nplaim hluav taws xob (cov khoom siv hluav taws xob tsis yog, nrog tsom rau kev tiv thaiv corrosion).
Muaj: Cov Khoom Hluav Taws Xob, Khoom Siv Khoom Siv Khoom Siv Khoom Siv, Ua Cua Ua Si, thiab lwm yam.
