ls weathering steel kim dua

Qhov zoo ntawm weathering steel
Zoo heev corrosion kuj
Kev tu-dawb thiab tsis tshua muaj nqi tag nrho

Ua tiav huab cua steel txuas hniav yuav tsum tau muaj kev saib xyuas me me lossis tsis tu ncua, ua rau lawv zoo tagnrho rau kev siv nyob rau hauv qhov chaw uas kev tu vaj tse nyuaj lossis kev tsim kho tsis zoo. Kev txiav txim siab los ntawm tag nrho cov nqi ntawm lub neej, tus nqi ntawm kev siv huab cua steel muaj qhov zoo dua li cov pa roj carbon zoo tib yam. Muaj ob hom huab cua steel: unpainted thiab pleev xim rau. Tag nrho lub neej voj voog tus nqi ntawm weathering steel txuas hniav yog soj ntsuam los ntawm kev sib piv nrog cov xim hlau txuas hniav ua piv txwv. Cov txiaj ntsig yog raws li nram no:

• Kev sib piv ntawm "tsis muaj painting weathering steel" thiab "zoo tib yam steel + painting". Thaum lub sij hawm tsim choj, tus nqi ntawm huab cua steel nce li ntawm 10% ~ 25% piv nrog cov qauv zoo tib yam, thiab tus nqi ntawm cov hlau vuam hlau rau huab cua steel nce li ntawm 50% ~ 70% piv nrog cov hlau zoo tib yam, yog li. Nws tuaj yeem pom tias tus nqi tsim kho ntawm huab cua steel choj yog kwv yees li 1.2 npaug ntawm tus choj zoo tib yam. Txawm li cas los xij, txiav txim siab tus nqi kos duab ntawm tus choj hlau zoo tib yam (tus nqi pleev xim rau kwv yees li 1/4 ntawm cov khoom siv ntawm tus choj), tus nqi pib ntawm huab cua steel choj yog ze rau tus nqi ntawm cov xim hlau, saib Table 1.
• Kev sib piv ntawm "weathering steel + painting" thiab "zoo tib yam steel + painting". Hauv qee qhov chaw corrosion kuj hnyav, huab cua hlau kuj yuav tsum tau pleev xim rau. Piv txwv tias tag nrho peb cov hlau txuas hniav yog pleev xim rau thaum lawv siv thawj zaug, tus nqi pib ntawm lub tsev nrog huab cua steel nce li ntawm 4.4% mus rau 12.2% piv rau kev siv cov hlau zoo tib yam, tab sis tag nrho cov nqi ntawm lub neej raug txo los ntawm 36.7% rau 39.8%. . Ib yam li ntawd, txij li kev saib xyuas tsawg tsawg, kev saib xyuas kev pheej hmoo cuam tshuam nrog rau yav tom ntej tuaj yeem pom tseeb txo qis, zam qhov teeb meem kev noj qab haus huv thiab kev nyab xeeb cuam tshuam nrog kev pleev xim thawj zaug. Saib Table 2 rau kev sib piv tshwj xeeb.

Cov txiaj ntsig ib puag ncig

Txij li cov huab cua ntawm cov hlau tuaj yeem pleev xim tsis tau lossis nrog cov txheej me me, qhov cuam tshuam rau thaj chaw ib puag ncig ntawm qhov tsis zoo ntawm cov organic compound (VOC) emissions los ntawm cov xim pleev xim rau saum npoo ntawm cov choj hlau zoo tib yam thiab cov cim ntawm cov khoom siv ntxuav tu los ntawm cov txheej txheem tu tom ntej (xws li. , sandblasting) tuaj yeem zam tau zoo heev lossis txo qis. Nyob rau tib lub sijhawm, huab cua hlau yuav hloov pauv raws sijhawm, nws cov xim ci thiab saturation siab dua li cov hlau zoo tib yam, thiab tuaj yeem tswj xyuas qhov zoo sib xws.
 

Nqi

Lwm qhov sib txawv loj ntawm Corten thiab cov hlau me me yog lawv tus nqi taw tes. Corten cov khoom feem ntau raug nqi ib ncig ntawm 50% ntau dua li qhov nruab nrab ntawm cov khoom siv hlau me me. Txawm li cas los xij, muab Corten lub neej ntev thiab kev saib xyuas qis dua, nws sawv cev rau kev nqis peev mus ntev. Cov hlau me me yeej yog ib qho txiaj ntsig zoo, tab sis yog tias muaj cov txheej txheem tiv thaiv, xws li hmoov txheej los yog galvanising, yog siv rau kev siv lub neej ntev ntxiv, tus nqi sib piv nrog Corten pib tawm.

Gnee Garden yog ib lub koom haum ntawm Gnee Group. Peb yog cov chaw tsim khoom lag luam sib koom ua ke, suav nrog lub qhov hluav taws kub, barbecues, dej nta, cua sov sab nraum zoov, grills, laj kab, cov ntxaij vab tshaus, planters thiab lwm yam.
