Daim ntawv thov
- A588 qib K Kub ntws cov huab cua hlau phaj yog siv nyob rau hauvChoj SivVim nws cov huab cua zoo heev thiab muaj zog siab.
Thaum nthuav tawm cov huab cua uas muaj cov ntaub ntawv txuas ntxiv, ib cov ntaub ntawv tiv thaiv oxide ruaj khov ntawm cov nqi hlau thoob plaws hauv tus choj lub neej.
Piv rau cov pa roj carbon hlau, A588 Qib K High Dag Zog Corten Steel Sheet Extends cov kev pabcuam lub neej ntawm Choj Cov Qauv ntawm Choj Cov Qauv ntawm 20-30 xyoos.
Thaum lub rooj sib tham txog cov kev xav tau ntawm cov txiaj ntsig zoo dua lossis sib npaug ntawm 345-620 mpa thiab rau kev siv tus me pose- seem qhov ntev.
Qhov hnyav no txo cov qauv hnyav, txhim kho kev lag luam tag nrho thiab kev nyab xeeb.
- Hauv kev tsim kho loj,A588 Qib K High zog Weatherig Hlau Ntawv yog siv rau cov kws ua tsom kwm, suab teeb meem, thiab kev txhawb nqa kev tsim qauv.
Nrog ib xyoos txhua xyoo corrosion tsuas yog 1 / 4-1 / 6 uas yog cov txheej txheem muaj kev tiv thaiv ruaj khov txawm tias tsis muaj txheej txheem lossis tsis muaj kev sib tw ntev.
Kev xyaum engineering qhia tias yog lub neej tsim muaj siab tshaj 40 xyoo hauv nroog hauv nroog ib puag ncig ib puag ncig ib puag ncig ib puag ncig ib puag ncig ib puag ncig ib puag ncig rau 20-30 xyoo hauv kev lag luam thiab cov khoom siv marrospheres.
- Hauv lwm txoj haujlwm tsim kho,A588 Qib K High Zog Corten Steel Phaj Tshawb kom muaj kev tso ntaub ntawv ntau ntxiv, ntim tsheb thauj khoom, thiab cov tshuab kev tsheb ciav hlau hnyav.
Nws ua kom pom kev zoo tshaj plaws - kub cuam tshuam todness (cuam tshuam rau lub zog loj dua los yog sib luag rau cov neeg enginees
Tsis tas li ntawd, nws lub zog siab dua rau 10-30% cov khoom siv hlau hluav taws xob hauv kev tsim, muab cov txiaj ntsig tseem ceeb hauv cov phiaj xwm loj.
ASTM A588 Qib k steel phaj yog qhov siab- Lub zog, qis} Cov huab cua muaj zog nrog cov kev siv tshwj xeeb hauv kev txhim kho atmospheric. Nws qhov chaw maj mam tsim kho cov txheej oxide tuab heev (patina) hauv cov huab cua ntuj.
Qhov no tsis tsuas yog txo qis cov khoom siv thiab cov nqi tsheb thauj mus los tab sis kuj txuas ntxiv txij nkawm mus los, cov nqi pheej yig rau kev kho txheej txheem thiab kev tiv thaiv kev tiv thaiv.
Hu rau tam sim no kom tau A588 tsocai
