ls corten corrosion kuj

Huab cua hais txog qhov tseeb tias cov hlau tiv taus huab cua ntau dua li cov hlau tsis muaj hlau vim nws cov tshuaj muaj pes tsawg leeg. Cov nyhuv corrosion-inhibiting ntawm txheej tiv thaiv yog tsim los ntawm qhov xwm ntawm nws cov qauv muaj pes tsawg leeg thiab tshwj xeeb tis thiab concentration ntawm alloying ntsiab nyob rau hauv nws.

Lub corrosion kuj ntawm weathering steel yog raws li nyob rau hauv lub tsim ntawm oxidized tiv thaiv txheej, hu ua patina, nyob rau saum npoo ntawm cov hlau. Raws li huab cua ib txwm muaj, patina tsim nyob rau hauv li ntawm 18-36 lub hlis yog tias qhov chaw ntub dej thiab qhuav.

Thaum pib, patina yog xim liab-xim av, tab sis nws darkens dhau sijhawm. Patina cov ntaub ntawv sai dua thiab tsaus dua nyob rau hauv kev lag luam ib puag ncig dua li nyob deb nroog. Nyob rau hauv ib puag ncig marine, tsim cov txheej txheem tiv thaiv ntawm patina yuav qeeb qeeb vim muaj cov tshuaj chlorides.
Nyob rau hauv ntau daim ntawv thov, weathering steels muab superior corrosion tiv thaiv rau lwm yam steels. Weathering steel yog tiv thaiv tus kheej: qhov chaw patina hloov mus rau hauv cov txheej txheem oxide nruj, uas ua rau cov txheej txheem corrosion. Cov hlau no yog cov khoom siv nyiaj txiag, ruaj khov, thiab cov khoom siv rov ua dua tshiab.

Huab cua txhais tau hais tias vim nws cov tshuaj muaj pes tsawg leeg, cov hlau yog resistant rau atmospheric corrosion dua li cov hlau tsis-alloyed. Cov nyhuv corrosion-inhibiting ntawm cov txheej tiv thaiv yog tsim los ntawm qhov xwm ntawm nws cov qauv muaj pes tsawg leeg thiab tshwj xeeb tis thiab concentration ntawm alloying ntsiab nyob rau hauv nws.
Thaum raug huab cua, txheej txheej tiv thaiv nto tsim thiab rov tsim dua tshiab. Cov nyhuv corrosion inhibition ntawm cov txheej tiv thaiv yog tsim los ntawm cov xwm txheej ntawm nws cov khoom siv thiab cov kev faib tawm tshwj xeeb thiab cov ntsiab lus ntawm cov alloying hauv nws. Thaum raug cuam tshuam los ntawm huab cua, cov txheej tiv thaiv saum npoo tsim thiab rov tsim dua tshiab.

Cov xwm txheej cuam tshuam rau huab cua ntawm Corten steel

Lub sij hawm tsim, kev loj hlob, thiab kev tiv thaiv ntawm weathered steel npog yog nyob ntawm qhov loj ntawm qhov corrosive qhov chaw. Cov teebmeem sib txawv thiab nyob ntawm qhov feem ntau ntawm huab cua huab cua (xws li kev nyab xeeb continental), macroclimate (xws li kev lag luam, nroog, marine, lossis kev nyab xeeb nyob deb nroog), thiab kev taw qhia ntawm cov qauv tsim (xws li raug los yog chaw nyob los ntawm huab cua, ntsug. los yog kab rov tav txoj hauj lwm).
Cov theem ntawm corrosive tshuaj nyob rau hauv cov huab cua kuj yuav tsum tau muab rau hauv tus account. Feem ntau, nyob rau hauv industrial, nroog, thiab nyob deb nroog kev nyab xeeb, npog tiv thaiv atmospheric corrosion. Thaum cov hlau no siv yam tsis muaj txheej tiv thaiv, tus tsim qauv yuav tsum coj mus rau hauv tus account qhov yuav tsum poob ntawm thickness vim corrosion thiab them rau qhov no los ntawm kev nce thickness ntawm cov khoom yog tias tsim nyog.

Qhov twg cov huab cua kis tau nrog cov tshuaj corrosive, cov pa tiv thaiv saum npoo yog pom zoo. Nyob rau hauv cov ntaub ntawv ntawm kev sib cuag nrog dej ntev, ntev raug rau cov av noo, los yog siv nyob rau hauv ntug hiav txwv dej, ib tug txheej yog tsim nyog. Muab piv rau cov hlau tsis muaj huab cua sib piv, cov xim pleev xim ntawm cov huab cua hlau tsis tshua muaj kev cuam tshuam rau kev puas tsuaj vim xeb.
Nrog rau atmospheric corrosion kuj ntau dua li cov hlau uas tsis yog-alloyed, COR-TEN steel yog nce raws li cov huab cua tiv thaiv steel rau siv nyob rau hauv cov tsev, txuas hniav, shipping ntim, thiab txoj kev loj qhia rails.
