Powder activated carbon yog ib hom nrov heev ntawm activated carbon. Yog li, puas yuav ntim cov hmoov activated carbon cuam tshuam qhov zoo ntawm cov khoom? Tom ntej no, cia kuv qhia rau koj!
Vim muaj kev cuam tshuam ntawm ib puag ncig kev tsim khoom, ntim khoom, kev thauj mus los, thiab kev cia khoom, hmoov activated carbon tuaj yeem nqus dej thiab cua, ua rau nws lub peev xwm adsorption txo. Yog tias nws tsis tau qhib ua ntej siv, nws yuav cuam tshuam rau lub peev xwm ntawm cov hmoov activated carbon rau adsorb tshav kub thiab impurities, thiab cuam tshuam rau qhov zoo ntawm cov formulation. Yog li ntawd, kev kho mob ua ntej yuav tsum tau ua raws li cov ncauj lus kom ntxaws ua ntej siv, uas tuaj yeem txhim kho lub peev xwm tshem tawm cov cua sov ntawm cov pa roj carbon activated. Cov kev sim tau pom tias cov cua sov qhov chaw tshem tawm cov nyhuv ntawm cov hmoov activated carbon yog qhov zoo dua li cov uas tsis tau kho cov pa roj carbon activated.
Feem ntau siv txoj kev kho ua ntej rau cov hmoov activated carbon muaj xws li:
Vim lub ntim ntim tsis zoo, nqus dej noo thiab cua yuav ua rau cov pa roj carbon activated adsorb ua ntej nws tuaj yeem tsaws. Nws tuaj yeem ci ntawm 120 degree. Tej zaum tom qab boiling kev kho mob.
Rau cov uas me ntsis alkaline los yog tsis ruaj tsis khov rau hlau ntsev, kua qaub los yog alkali kev kho mob yuav tsum tau siv thaum siv hmoov activated carbon. Cov txheej txheem nthuav dav: Siv 1 feem ntawm cov hmoov activated carbon, ntxiv 4 feem ntawm 5% sodium hydroxide, boil rau 30 feeb, lim kom qhuav, ntxuav nrog dej txhaj kom txog thaum nruab nrab, ces ua ntu zus nrog 4 feem ntawm 5% hydrochloric acid thiab 4 feem ntawm txhaj dej rau 30 feeb, lim kom qhuav, thiab rov qab yaug nrog dej txhaj tshuaj kom txog thaum tsis muaj chloride ions, ces qhuav.
Cov saum toj no yog ib qho kev taw qhia txog hmoov activated carbon. Yog tias koj muaj lus nug ntxiv, txais tos sab laj!
