Silica Powder rau tshuaj tua kab ua tus cab kuj los txhim kho kev nqus
Silicon dioxide, feem ntau hu ua silica, yog cov khoom tseem ceeb ntawm lub ntiaj teb crust thiab muaj kev siv dav hauv ntau yam lag luam. Nws kuj tseem ua haujlwm rau ntau yam khoom ua liaj ua teb, suav nrog tshuaj tua kab thiab fungicides. Silica hmoov yog amorphous daim ntawv ntawm silicon dioxide thiab yog ib qho kev xaiv nrov raws li cov cab kuj rau cov tshuaj tua kab.
Silica hmoov rau tshuaj tua kab yog cov khoom ntxeem tau nrog thaj chaw siab uas tuaj yeem nqus cov tshuaj tua kab thiab txhim kho lawv cov kev faib tawm ntawm cov nroj tsuag. Qhov no ua rau cov tshuaj tua kab ntau dua ntawm cov qoob loo, txhim kho nws cov txiaj ntsig. Silica hmoov muaj cov tshuaj toxicity tsawg heev, ua rau nws muaj kev nyab xeeb siv hauv kev ua liaj ua teb.
Thaum siv los ua cov cab kuj rau cov tshuaj tua kab, silica hmoov pab txhim kho qhov nqus ntawm cov tshuaj tua kab rau hauv cov nroj tsuag. Qhov no yog ua tiav los ntawm nws lub cev tshwj xeeb xws li qhov ntxeem tau uas tso cai rau thaj chaw siab thiab adsorption ntawm cov tshuaj tua kab. Tsis tas li ntawd, qhov me me me me ntawm cov hmoov ua rau muaj kev sib cuag ntawm cov tshuaj tua kab ntawm cov nroj tsuag, uas txhim kho qhov nqus tau.
Silica hmoov kuj yog cov tshuaj inert, ua rau nws muaj txiaj ntsig zoo rau kev nqa cov tshuaj tua kab acidic thiab alkaline. Nws muaj qhov nruab nrab pH, uas ua kom ntseeg tau tias nws tsis cuam tshuam nrog cov khoom siv tshuaj tua kab. Tsis tas li ntawd, cov hmoov tsis tawg yooj yim, uas txhais tau hais tias nws muaj lub neej txee ntev thiab tuaj yeem ruaj ntseg khaws cia rau lub sijhawm ntev.
Hauv cov ntsiab lus, silica hmoov yog qhov kev xaiv zoo tshaj plaws los ua cov khoom siv tshuaj tua kab vim nws cov txiaj ntsig ntau. Nws txhim khu kev faib cov tshuaj tua kab ntawm cov qoob loo, kom ntseeg tau tias muaj ntau dua cov tshuaj ntawm cov nroj tsuag. Nws cov khoom tshwj xeeb ntawm lub cev kuj ua rau kom muaj kev nqus ntawm cov tshuaj tua kab rau hauv cov nroj tsuag, ua kom nws zoo dua. Thaum kawg, nws muaj kev nyab xeeb siv thiab muaj lub neej txee ntev, ua rau nws yog qhov kev xaiv zoo tshaj plaws rau cov neeg ua liaj ua teb thiab cov kws ua liaj ua teb.
