Q: Qhov xwm txheej uas cuam tshuam dab tsi rau kev pabcuam lub neej ntawm galvanized profiles?
A: Zinc Txheej Thickness: kub-dip Galvanizing (50) 100μm +) Txias-dip Galvanizing (5 ~ 30μm) {{}
Ib puag ncig corrosiveness: qhuav sab nraum zoov
Q: Dab tsi yog lub tswv yim pabcuam kev pabcuam ntawm Galvanized profile nyob rau hauv cov chaw yuav sib txawv?
A: Hauv chav qhuav: kub-dip galvanized profiles rau ntau tshaj 50 xyoo (zinc txheej (zinc txheej yog yeej tsis corroded); Mob khaub thuas-dip galvanized profiles rau 20 ~ 30 xyoos (zinc txheej corrodes maj mam) .
Sab Nraum Zoov Sab Nraum: kub-dip galvanized profiles rau 20 ~ 50 xyoo (zinc txheej tau maj mam noj thiab xav tau tshuaj xyuas ib txwm); Mob khaub thuas-dip galvanized profiles rau 5 ~ 15 xyoos (zinc txheej yog nyias thiab nquag mus liab xeb) .
Tsaus ntuj ib puag ncig: kub-dip galvanized profiles rau 15 ~ 30 xyoos (zinc txheej accelerates corrosion); Mob khaub thuas-dip galvanized profiles rau 3 ~ 8 xyoo (yooj yim rau xeb thiab xav tau kev saib xyuas nquag).
Ntug dej hiav txwv / cov ntsev ntau Mob khaub thuas-dip galvanized profiles rau 2 ~ 5 xyoos (zinc txheej corrodes thiab perforates sai sai) {}}
Industrial acid-puag ib puag ncig ib puag ncig rau 5 ~ 10 xyoo (Zinc Txheej tsis nrawm thiab yuav tsum muaj kev tiv thaiv muaj zog); Mob khaub thuas-dip galvanized profiles rau 1 ~ 3 xyoos (tsis muaj feem xyuam, xav tau kev tiv thaiv ntau dua)
Q: Dab tsi cuam tshuam rau kev pabcuam lub neej ntawm stainless hlau?
A: stainless hlau qauv: 304 <316 <904 thiab lwm cov qauv siab {}}
Corrosive nruab nrab hom: chloride ions (xws li seaterater) ua qhov kev hem thawj loj tshaj plaws rau cov hlau tsis muaj zog, thiab qhov chaw xav tau txawv.
Kev ncaj ncees saum npoo: kev puas tsuaj rau cov zaj duab xis hla (xws li khawb, vuam tsis xws luag) yuav ua rau corrosion .
Q: Dab tsi yog qhov tseem ceeb tshaj plaws uas ua rau qhov sib txawv hauv kev pabcuam lub neej ntawm Galvanized steel thiab stainless hlau?
A: galvanized profiles: vam khom cov txheej txheej, lub neej ntev yog muaj feem cuam tshuam nrog cov txheej luv ntawm zinc txheej, thiab nws yog i6 {}}
Stainless hlau: cia siab rau tus kheej-kho cov yeeb yaj kiab passivation, lub neej ntev tuaj yeem ua tiav "semi-titefortion" corrosion tsis kam.
Q: Dab tsi yog qhov cuam tshuam ntawm kev saib xyuas ntawm lub neej?
A: Galvanized profiles: tsis tu ncua xeb thiab rov thov cov xim xeb los ntawm cov choj muaj peev xwm txuas ntxiv lub neej pabcuam los ntawm ntau tshaj 50 xyoo) {8}
Yuav tsum muaj cov hlau stainless: Feem ntau, tsis tas yuav muaj kev txij nkawm (tab sis nyob rau hauv cov kev qias neeg ib txwm muaj los tiv thaiv cov neeg ua yeeb yam los ntawm kev puas tsuaj los ntawm impurities .
