Q: Dab tsi yog daim ntawv thov tseem ceeb ntawm Q235 phaj?
A: Q235 phaj yog dav siv hauv:
Kev tsim kho engineering: steel qauv kab teeb, kab, purlins, pem teb slabs, thiab lwm yam.
Mechanical manufacturing: tshuab cuab tam txaj, brackets, plhaub, thiab lwm yam.
Tsheb thauj mus los: tsheb compartments, nkoj decks, choj Cheebtsam, thiab lwm yam.
Lwm qhov chaw: ntim, kav dej, tshuab ua liaj ua teb, thiab lwm yam.
Q: Q235 puas siv tau los ua cov hlab ntsha siab?
A: Tsis yog Q235 phaj yog cov khoom siv carbon steel, uas tsis ua tau raws li qhov yuav tsum tau muaj zog thiab toughness ntawm cov hlab ntsha. Cov hlab ntsha siab yuav tsum siv cov hlau tshwj xeeb xws li Q345R thiab Q245R.
Q: Q235 puas tuaj yeem siv rau hauv qhov chaw qis - qhov kub thiab txias?
A: Nws nyob ntawm qib. Q235A thiab Q235B tsis haum rau qhov chaw qis - qhov kub thiab txias. Q235C tuaj yeem siv rau hauv 0℃ib puag ncig, thiab Q235D tuaj yeem siv rau hauv -20℃ib puag ncig. Rau qhov kub thiab txias ib puag ncig, nws raug nquahu kom xaiv cov phaj tshwj xeeb uas tsis kub kub.
Q: Q235 puas tuaj yeem siv los ua cov iav thiab cov ncej?
A: Feem ntau tsis yog. Q235 phaj muaj lub zog qis thiab hnav tsis zoo, uas tsis tuaj yeem ua tau raws li qhov yuav tsum tau ua ntawm cov iav thiab cov ncej. Iav thiab shafts feem ntau yog ua los ntawm cov pa roj carbon nruab nrab (xws li 45 # steel) lossis hlau alloy.
Q: Dab tsi yog qhov kev kho saum npoo ntawm Q235 phaj?
A: Cov kev kho saum npoo feem ntau suav nrog:
Kub-dip galvanizing: txhim kho corrosion kuj.
Painting: tiv thaiv -corrosion thiab zoo nkauj.
Pickling thiab passivation: tshem tawm nto oxide nplai thiab xeb.
Oiling: tiv thaiv xeb thaum khaws cia thiab thauj.
Q: Q235 phaj ntim li cas rau kev thauj mus los?
A: Q235 phaj feem ntau yog ntim rau hauv pob. Txhua lub pob yog tsau nrog cov hlua hlau, thiab qhov saum npoo yog npog nrog cov yas zaj duab xis los yog cov ntawv tsis muaj dej kom tiv thaiv xeb thiab kev puas tsuaj thaum thauj. Rau kev thauj mus los hauv hiav txwv, peb tseem yuav siv cov ntim seaworthy los tiv thaiv cov ntsev tsuag corrosion.
