Kev tshawb fawb txog Corrosion Resistance ntawm Basalt Fiber Concrete

Pob zeb corrosion yog ib qho ntawm cov laj thawj tseem ceeb ntawm cov pob zeb ua kom tsis muaj zog, thiab cov teeb meem kev txhim kho pob zeb ua rau muaj kev lag luam loj loj txhua xyoo. Txhawm rau txo qhov kev poob nyiaj txiag los ntawm kev ua vaj tse corrosion, nws yog ib qho tseem ceeb heev los kawm txog kev tiv thaiv corrosion ntawm Basalt Fiber ntau pob zeb.

Tam sim no, kev tshawb fawb txog kev tiv thaiv corrosion ntawm basalt fiber ntau yog koom nrog kev sib xyaw ua ke hauv cov kev daws teeb meem sib txawv rau qee lub sijhawm thiab tshuaj xyuas qhov kev tiv thaiv corrosion ntawm basalt fiber ntau los ntawm kev sim. Cov kev tshawb fawb sim tau pom tias lub zog compressive thiab flexural zog ntawm basalt fiber ntau pob zeb txo qis raws li qhov concentration ntawm cov tshuaj corrosive nce, thiab lawv kuj txo nrog qhov nce ntawm corrosion lub sij hawm nyob rau hauv ib tug corrosive tov ntawm tib concentration. Qhov sib ntxiv ntawm basalt fibers tuaj yeem txhim kho cov compressive thiab flexural lub zog ntawm pob zeb hauv ib puag ncig corrosive. Txawm li cas los xij, ntxiv ntau ntau ntawm basalt fibers yuav ua rau txo qis hauv cov pob zeb compressive thiab flexural zog. Qee cov kws tshawb fawb tau tso cov qauv basalt fiber ntau hauv cov tshuaj sodium sulfate rau 90 hnub thiab pom tias qhov sib ntxiv ntawm basalt fibers tuaj yeem txhim kho cov pob zeb tawg, yog li txhim kho nws cov corrosion kuj. Nyob rau hauv cov xwm txheej no, qhov zoo tshaj plaws tawg tiv thaiv tau tiav nrog basalt fiber ntau cov ntsiab lus ntawm 0.1%. Nyob rau tib lub sijhawm, cov qauv basalt fiber ntau tau muab tso rau hauv cov tshuaj sodium chloride rau 90 hnub, 180 hnub, thiab 270 hnub. Kev sib piv tau pom tias qhov sib ntxiv ntawm basalt fibers tuaj yeem cuam tshuam txoj kev loj hlob ntawm cov kab nrib pleb thaum ntxov hauv cov pob zeb, thiab thaum lub sij hawm corrosion nce, qhov zoo tshaj plaws kev tiv thaiv yog tiav nrog ib tug basalt fiber ntau ntim cov ntsiab lus ntawm 0.1%. Qhov sib ntxiv ntawm qhov tsim nyog ntawm basalt fibers tuaj yeem txhim kho cov pob zeb tiv thaiv corrosion los ntawm sodium sulfate thiab sodium chloride. Compressive kev ntsuam xyuas ntawm cov qauv soaked nyob rau hauv ib tug corrosive tov pom tias qhov sib ntxiv ntawm basalt fibers tuaj yeem txhim kho cov pob zeb deformation muaj peev xwm thiab qhov kawg ntawm cov kabmob, nrog cov txiaj ntsig zoo tshaj plaws ntawm cov ntsiab lus basalt fiber ntau ntawm 0.1%.

Hauv cov ntsiab lus, qhov ntxiv ntawm basalt fibers tuaj yeem txhim kho corrosion kuj ntawm pob zeb. Txawm li cas los xij, cov kev sim tam sim no feem ntau tsom rau ib qho kev corrosive (xws li sulfate lossis chloride corrosion), thiab xav tau kev sib tham ntxiv rau kev tshawb fawb txog kev daws teeb meem ntawm ob lossis ntau dua cov tshuaj corrosive.
