Q235 steel coil tiv thaiv- kev kho corrosion (feem ntau siv hauv kev tsim kho)?
A: Kev tshem tawm xeb (sandblasting/shot blasting) → primer (epoxy zinc-paint paint) → intermediate paint (epoxy micaceous iron oxide paint) → topcoat (polyurethane/fluorocarbon paint), los yog kub-dip galvanizing, kom ntev lub neej kev pab ntawm lub tsev.
Q235 steel coil tivthaiv deformation kho (kev tsim kho)?
A: Txias straightening (mechanical / phau ntawv qhia), kub tsawg dua los yog sib npaug ntawm chav tsev kub; kub straightening (nplaim taws kub, kub 600-800 degree), overheating yog nruj me ntsis txwv tsis pub, xyuas qhov ntev thiab txhua yam khoom tom qab straightening.
Q235 steel kauj kev lag luam zoo hauv kev tsim kho?
A: Kev smelting yooj yim, tus nqi qis, zoo heev plasticity / weldability, tsis ua tiav, thiab tag nrho cov nqi qis dua siab dua - steel zog, ua rau nws yog thawj qhov kev xaiv rau tus nqi - kev ua tau zoo hauv cov qauv siv.
Thaum twg siv Q235 steel kauj thiab thaum twg siv siab -lub zog steel hauv kev tsim kho?
A: Rau lub teeb loads, tus qauv ncua sij hawm, qhov kub thiab txias, thiab kev siv nyiaj tsawg, xaiv Q235; rau cov khoom hnyav, qhov loj me, siab- cov tsev nce siab, thiab qis- kub dynamic loads, xaiv Q355 thiab siab dua.
Dab tsi yog yav tom ntej tiam sis hauv Q235 steel coil daim ntawv thov hauv kev tsim kho?
A: Nws yuav yog cov khoom siv tseem ceeb rau kev tsim kho; nrog rau qhov sib txawv ntawm lub teeb yuag thiab kev ua haujlwm siab, nws yuav siv ua ke nrog Q355 thiab lwm yam khoom siv; ntsuab ua thiab ntse txheej yuav txhim kho nws adaptability thiab durability nyob rau hauv kev tsim kho.
