1. Puas yog Q235 welded kav xav tau los tiv thaiv- kev kho corrosion?
Yog lawm. Txawm hais tias Q235 steel muaj qee qhov kev tiv thaiv corrosion nyob rau hauv qhov chaw qhuav, nws yooj yim rau xeb hauv av, corrosive, lossis ib puag ncig sab nraum zoov. Yog li ntawd, kev tiv thaiv- kev kho corrosion (xws li galvanizing, painting, lossis epoxy txheej) feem ntau yuav tsum tau ua kom nws lub neej ua haujlwm ntev.
2. Dab tsi yog qhov siab tshaj plaws ntawm Q195 welded kav uas tuaj yeem tsim tau?
Qhov siab tshaj plaws txoj kab uas hla ntawm Q195 welded kav feem ntau yog nyob ib ncig ntawm 630 hli. Vim yog lub zog qis ntawm Q195 steel, nws tsis haum rau kev tsim cov khoom siv ntxiv - txoj kab uas hla loj lossis tuab - cov kav dej, uas feem ntau yog siv rau cov kav dej me me thiab nruab nrab.
3. Dab tsi yog qhov sib txawv ntawm phab ntsa tuab ntawm Q215 welded kav?
Cov phab ntsa tuab ntau ntawm Q215 welded kav yog 1.5-10 hli. Nws tuaj yeem hloov kho raws li daim ntawv thov scenario: nyias- cov kav dej (1.5-}3 mm) yog siv rau cov qauv teeb, thiab cov kav dej tuab (3-10 mm) yog siv rau kev thauj mus los ntawm cov kua dej tsawg.
4. Dab tsi yog daim ntawv thov ntawm Q235 welded kav?
Q235 welded kav muaj ntau daim ntawv thov, suav nrog: nruab nrab thiab qis - kev thauj mus los ntawm cov kua dej siab (dej, roj, roj), kev tsim vaj tsev (steel thav duab, scaffolding, choj txhawb nqa), kev tsim kho tshuab (cov kav dej, lub tes tsho tiv thaiv), thiab kev tsim vaj tsev hauv nroog (cov kav dej phwj tuaj, cov kav dej).
5. Q195 thiab Q235 steels puas tuaj yeem sib xyaw ua cov kav dej welded?
Nws tsis pom zoo. Q195 thiab Q235 muaj cov khoom siv sib txawv thiab cov tshuaj sib xyaw ua ke, uas yuav ua rau lub zog tsis sib xws thiab vuam zoo ntawm cov yeeb nkab welded, cuam tshuam rau nws cov kev pabcuam thiab kev nyab xeeb. Welded kav yuav tsum tau tsim nrog tib qib ntawm cov hlau.
