Kev tshawb fawb txog kev tiv thaiv corrosion ntawm basalt fiber ntau pob zeb los pab txhim kho pob zeb ua kom ntev

Kev tshawb fawb txog corrosion kuj ntawm Basalt Fiber ntau pob zeb qhia tau hais tias qhov sib tov ntawm qhov tsim nyog tus nqi ntawmbasalt fibers tuaj yeem txhim kho qhov kev tiv thaiv corrosion ntawm pob zeb, uas muab lub tswv yim tshiab los daws qhov teeb meem ntawm kev ua haujlwm tsis zoo los ntawm kev ua vaj tse corrosion.
Pob zeb corrosion yog ib qho tseem ceeb ua rau nws cov durability degradation, uas ua rau poob nyiaj txiag loj txhua xyoo. Txhawm rau txo qhov kev poob nyiaj txiag los ntawm kev ua vaj tse corrosion, nws yog qhov tseem ceeb heev los kawm txog kev tiv thaiv corrosion ntawm basalt fiber ntaupob zeb. Tam sim no, cov kev tshawb fawb cuam tshuam feem ntau yog los ntawm cov Pob zeb Specimen immersed nyob rau hauv sib txawv corrosion daws los soj ntsuam cov kev hloov nyob rau hauv nws compressive zog, flexural zog thiab lwm yam khoom.

Kev tshawb nrhiav pom:

• Compressive zog thiab flexural zog: lub zog compressive thiab flexural zog ntawm basalt fiber ntau pob zeb txo qis nrog qhov nce ntawm corrosive tov concentration thiab corrosion lub sij hawm, tab sis qhov sib xyaw ntawm cov khoom tsim nyog ntawm basalt fibers tuaj yeem txhim kho nws lub zog compressive thiab flexural zog hauv corrosive ib puag ncig. Txawm li cas los xij, kev koom ua ke ntau dhau ntawm basalt fibers yuav ua rau txo qis zog.
• Anti-cracking khoom: Tom qab immersed nyob rau hauv sodium sulfate tov rau 90 hnub, anti-cracking cuab yeej ntawm basalt fiber ntau pob zeb tau txhim kho zoo, uas qhov zoo tshaj plaws tau ua tiav thaum lub ntim admixture ntawm basalt fiber yog 0.1%.
• Crack inhibition: Tom qab immersed nyob rau hauv sodium chloride tov rau 90 hnub, 180 hnub thiab 270 hnub, basalt fiber ntau tuaj yeem cuam tshuam txoj kev loj hlob ntawm cov kab nrib pleb thaum ntxov hauv pob zeb, nrog kev ua haujlwm zoo tshaj plaws los tiv thaiv kev tawg thaum lub ntim ntau npaum li 0.1%.
• Deformation muaj peev xwm thiab qhov kawg bearing muaj peev xwm: Cov kev ntsuas compressive ntawm cov qauv uas tau muab tso rau hauv cov tshuaj corrosive pom tau tias qhov sib ntxiv ntawm basalt fibers tuaj yeem txhim kho lub peev xwm deformation thiab qhov kawg ntawm lub peev xwm ntawm cov pob zeb, thiab cov nyhuv yog qhov zoo tshaj plaws thaum lub ntim ntau npaum li 0.1%.

Txawm hais tias cov kev tshawb fawb uas twb muaj lawm tau lees paub qhov txiaj ntsig zoo ntawm basalt fibers ntawm kev tiv thaiv corrosion ntawm cov pob zeb, feem ntau ntawm cov kev tshawb fawb tam sim no tsom rau ib qho kev mob corrosive (xws li sulfate lossis chloride corrosion), thiab muaj tsawg dua kev tshawb fawb txog kev sib xyaw ntawm ntau yam tshuaj corrosive. Tsis tas li ntawd, cov kev tshawb fawb uas twb muaj lawm yog kev txhawj xeeb txog cov txiaj ntsig ntawm fiber ntau admixture ntawm cov khoom siv kho tshuab, lub neej yav tom ntej yuav tsum tau tsim kom muaj kev phom sij ion yaig thiab kev nkag mus thiab lwm yam ntawm kev kawm.
Cov kws tshaj lij tau hais tias kev tshawb fawb ntawm basalt fiber ntau pob zeb muab kev txhawb nqa tseem ceeb los txhim kho lub zog ntawm cov pob zeb, thiab xav tias yuav siv dav hauv marine engineering, chemical chaw thiab lwm qhov chaw corrosive yav tom ntej.
