1.Vim li cas txias-rolled coils tshwj xeeb yog tsim rau ua txias-tsim txee?
Txias dabtsi yog khoov yog txheej txheem uas siv cov txheej txheem txuas ntxiv kom maj mam khoov hlau sawb mus rau hauv ib qho tshwj xeeb ntoo khaub lig-sectional duab ntawm chav tsev kub. Cov yam ntxwv ntawm txias -rolled coils yog zoo kawg nkaus haum rau cov txheej txheem no:
Qhov zoo tshaj plaws ntawm qhov chaw: Txias-cov coils muaj qhov du, tiaj tiaj tsis muaj oxide nplai, ua rau muaj qhov zoo nkauj ntawm cov txee uas tuaj yeem pleev xim yam tsis muaj kev kho mob ntxiv, nrog rau cov txheej txheem zoo heev.
Precise dimensional tolerances: Kev tswj kom meej ntawm thickness thiab dav hauv txias-rolled coils ua kom qhov sib xws thiab ruaj khov ntawm cov khoom txee tom qab tsim, uas yog qhov tseem ceeb rau cov tshuab txee uas xav tau siab - kev sib dhos precision.
Zoo formability: Annealed txias- dov coils (feem ntau SPCC-SD, piv txwv li, "lub xeev mos") muaj cov yas zoo thiab ductility, muaj peev xwm tiv taus txoj kev khoov, curling, thiab ribbing deformations thaum lub caij txias khoov yam tsis muaj tawg.
Lub zog siab thiab nruj: Piv rau kub- dov coils, txias- dov coils ua tiav lub zog ntau dua los ntawm kev ua haujlwm tawv, tso cai rau cov txee kom muaj peev xwm txaus- cov kabmob muaj peev xwm txawm tias cov khoom sib dua thiab sib dua.
2.Qhov txheej txheem ntau lawm kab yog dab tsi rau txias -tsim txee?
Cold rolled coil uncoiling → Straightening → Roll forming → Fixed -ntev txiav → Punching / riveting → Vuam (rau qee qhov chaw) → Kev kho deg (corrosion tiv thaiv core) → Ntim
3.Yuav xaiv cov ntaub ntawv li cas?
Qib: Cov khoom siv feem ntau yog SPCC (Suav tus qauv) lossis DC01 (tus qauv European) mos-lub xeev (A lossis SD) cov ntaub ntawv los xyuas kom meej qhov txias txias zoo.
Nto: Rau kev yooj yim ntawm kev tiv thaiv corrosion tom ntej, kub -dip galvanized steel coils (SGCC) lossis electro-galvanized steel coils (SECC) yog qhov zoo dua los ua cov khoom siv hauv paus kom ua tiav "substrate corrosion tiv thaiv".
Thickness: Nyob ntawm cov khoom khib nyiab- qauv tsim, txias- dov coils nrog lub thickness ntawm 1.0mm txog 3.0mm feem ntau yog siv.
4.Yuav ua li cas los tiv thaiv- kev kho corrosion ntawm qhov chaw?
Shelving feem ntau yog nyob rau hauv ib puag ncig warehouse, uas tej zaum yuav raug rau ya raws thiab condensation, ua rau corrosion tiv thaiv tseem ceeb heev.
Kev daws teeb meem: Galvanized substrate + hmoov txheej
Siv galvanized steel coils (SGCC / SECC) raws li cov khoom siv raw muab cov txheej txheem tiv thaiv cathodic thawj zaug.
Tom qab txias khoov, phosphating pretreatment yog ua, ua raws li epoxy resin hmoov txheej los yog polyester txheej. Qhov no tsim kev tiv thaiv ob npaug ntawm "galvanized txheej + organic txheej," uas ua rau lub neej ntev thiab zoo nkauj. Qhov no yog txheej txheem txheej txheem rau nruab nrab - mus rau - siab - kawg shelving.
Kev daws teeb meem kev lag luam: Txias-Rolled Substrate + Zuag qhia tag nrho Post-Kev ua haujlwm
Siv cov khaub thuas zoo tib yam -rolled coils (SPCC) rau kev tsim, ua raws li tag nrho cov kub-dip galvanizing. Kev tiv thaiv corrosion zoo heev, tab sis qhov saum npoo yuav tsis zoo li du thiab zoo nkauj, thiab qhov kub thiab txias yuav ua rau me ntsis deformation.
Xwb, cov kab tiav ntawm "pickling thiab phosphating + electrophoretic primer + hmoov txheej" tuaj yeem siv. Kev ua tau zoo heev, tab sis kev nqis peev loj dua.
5.Yuav ua li cas txiav txim siab cov ntaub ntawv xav tau?
Rau lub teeb thiab nruab nrab -lub luag haujlwm shelving, galvanized txias-rolled coil (SGCC) yog siv ncaj qha.
Rau shelving nrog siab load- bearing peev xwm thiab zoo li yuav tsum tau, ib tug ua ke ntawm txias- dov coil substrate thiab ib tug ua tiav txheej kab yog siv.
Thaum ua kom muaj kev ua tau zoo, cov ntaub ntawv annealed mos raug xaiv los lav qhov zoo ntawm qhov txias txias.
