1.What yog qhov sib txawv ntawm cov ntaub ntawv raw thiab cov txheej txheem ntawm SECC thiab Secd?
Secc yog tsim los ntawm cov pa txias txias - rolled steel ntawv (SPCC) uas yog electrolytically galvanized. Secd, raws li SPCD, yog tsim los ntawm kev kho cov tshuaj lom neeg muaj pes tsawg leeg, xws li txo cov roj carbon thiab phosphorus cov ntsiab lus, thiab ua kom zoo dua qhov txheej txheem anealing.
2.What yog qhov sib txawv ntawm kev ua kom sib sib nqus ntawm SECC thiab Secd?
SECC yog ib qho hluav taws xob {{}} galvanized steel ntawv nrog qhov nruab nrab tob {1} {- 25%. Nws yog qhov tsim nyog rau cov ntawv thov stamping yooj yim, xws li kev tsim cov txheej txheem yooj yim xws li cov cuab yeej siv thiab cov khoom siv hluav taws xob. Secd yog lub electro - galvanized steel ntawv rau kev sib nqus, nrog kev sib sib zog nqus tau ntau dua 30%. Nws muaj kev sib sib zog nqus- teeb duab kev ua tau zoo thiab haum rau qhov uas xav tau lub qhov rooj sab hauv thiab cov nruas ntawm cov tshuab ntxhua khaub ncaws.
3.Qhov dab tsi yog qhov sib txawv ntawm cov neeg kho tshuab ntawm SECC thiab Secd?
Secc muaj cov khoom siv tsis tshua muaj zog, nrog rau tsis lees txais lub zog ua kom lub zog ua kom zoo. Nws yog feem ntau haum rau cov ntawv thov uas yuav tsum tau siv tsawg dua cov khoom siv uas xav tau. Secd feem ntau muaj cov txiaj ntsig lub zog ntawm tsawg dua lossis sib npaug ntawm 280 mpa thiab lub zog tensile ntawm 300-400 mpa. Nws nthuav tawm cov khoom ua pov thawj zoo heev ntxiv thiab tuaj yeem tiv taus qhov tseem ceeb tsis muaj kev tawg thaum lub sijhawm sib sib zog nqus.
4.What yog qhov sib txawv ntawm cov nqe ntawm Secc thiab Secd?
Txij li thaum Secd muaj siab dua ntawm substrate tshuaj muaj tshuaj lom neeg thiab cov txheej txheem ntau lawm, nws tus nqi feem ntau yog siab dua li secc.
5.Qhov dab tsi sib txawv hauv kev xeb tsis kam ntawm Secc thiab Secd?
Lub corrosion tsis kam ntawm Secc thiab Secd tsis txawv ntau. Yog hais tias cov txheej txheej tuab yog tib yam, cov xeb tsis kam ntawm ob yog yeej zoo ib yam; Yog hais tias txheej txheej tuab yog txawv, cov tuab dua txheej, qhov zoo dua rau corrosion tsis kam.
