Silica gel desiccant tau dhau los ua cov khoom siv feem ntau desiccant ntawm kev ua lag luam. Txawm li cas los xij, vim muaj ntau qhov sib txawv ntawm ntau silica gel tuam ntxhab nyob hauv thaj chaw muaj peev txheej, kev siv tshuab ntau lawm, kev tswj kom zoo, tswj kev lag luam, thiab lwm yam, qhov zoo ntawm cov khoom lawv ua yog txawv. Thaum tsis muaj cov cuab yeej kuaj kev ua haujlwm, cov khoom lag luam zoo tsuas yog txiav txim siab los ntawm kev soj ntsuam pom thiab qee txoj kev yooj yim. Cov hau kev no tseem tau ua rau ntau tus neeg hauv qhov kev tsis nkag siab no.
1. Txog kev txiav txim siab adsorption muaj peev xwm thiab cov ntsiab lus dej
Rau kev txiav txim siab ntawm cov dej ntsiab lus ntawm silica gel, feem ntau txoj kev siv rau cov tuam txhab desiccant muaj raws li hauv qab no:
1. Tso me me ntawm silica gel desiccant mus rau hauv dej thiab saib qhov sib zog ntawm qhov tawg thaum nws ntsib dej: qhov tawg tau nrawm thiab qhov cuam tshuam tawg yog qhov muaj zog, tom qab ntawd cov khoom lag luam pom tau tias muaj dej tsawg cov ntsiab lus thiab muaj peev xwm zoo adsorption Cov.
Nco tseg: Qhov dej tawg tus nqi ntawm silica gel desiccant tsis muaj kev sib raug zoo nrog cov dej ntsiab lus thiab adsorption muaj peev xwm ntawm silica gel. Nws tsis tuaj yeem cuam tshuam cov dej nqus ntawm qhov desiccant zoo heev, vim tias" tawg" los yog tsis yog tsuas yog ib pliag xwb, thiab theem ntawm kev nqus dej yog tas mus li. Cov ntaub ntawv ua pov thawj tau pom tseeb tias qee cov tuam ntxhab txhob txwm tsim cov khoom lag luam nrog" tus nqi tawg &; uas cov dej ntsiab lus nce mus txog lossis siab dua 15%, thiab lawv cov peev xwm adsorption qis dua cov qauv kev lag luam, uas yog qhov tsis muaj qhov tseeb.
2. Sib khi me me ntawm silica gel desiccant thiab me me ntawm cov xim hloov silica gel ua ke, thiab soj ntsuam qhov ceev ntawm qhov hloov xim silica gel. Lub qeeb qeeb tsis tau pom tseeb tias cov ntsiab lus dej ntawm qhov khoom yog tsawg.
Nco tseg: Qhov kev kuaj pom no yog qhov muaj txuj ci zoo heev, tab sis nws tsuas yog piav qhia seb cov dej ntsiab lus ntawm silica gel desiccant kuaj ntau dua li cov xim-hloov silica gel. Tsis tas li ntawd, cov xim hloov xim silica gel tsim los ntawm cov chaw tsim khoom lag luam, vim qhov sib txawv cov ntsiab lus ntawm cov khoom siv ntxiv rau, kuj tseem yuav ua rau qhov ceev ceev ntawm cov xim-hloov silica gel nws tus kheej yuav txawv. Yog li, peb tsis tuaj yeem ntseeg siab los ntawm qhov kev tshawb pom no.
3. Noj me me ntawm silica gel desiccant thiab tso nws sab nraum zoov rau 2 hnub tom qab hnyav. Tom qab ntsuas, suav qhov sib txawv ntawm ob qho kev ntsuas los ntawm qhov hnyav no. Yog tias qhov sib txawv loj heev, nws tau suav hais tias cov khoom muaj cov khoom lag luam muaj adsorption zoo. Rau
Nco tseg: Lub hauv paus ntsiab lus ntawm txoj kev no yog qhov tseeb, tab sis vim tias qhov chaw sab nraud ib puag ncig tau hloov pauv tas li, qhov tshwm sim los ntawm cov qauv no tsis tuaj yeem ntseeg tau.
4. Siv me me ntawm silica gel desiccant thiab tuav nws khov kho hauv koj txhais tes, thiab xav tias nws puas kub. Yog tias nws kub, nws ua pov thawj tias nws qhov zoo yog qhov zoo.
Nco tseg: Silica gel desiccant yuav tso tawm qee qhov kub thaum nws nqus dej, tab sis nws txoj kev ua tsis muaj tseeb raws li kev xav cuav.

2. Hais txog dimethyl fumarate DMF
Dimethyl fumarate DMF yog tus neeg sawv cev ywj siab rau yus tus kheej. Nws yog cov organic compound synthesized los ntawm qee yam tshuaj raw cov ntaub ntawv. Nws nkag mus rau cov cell membrane ntawm cov kab mob me me thiab nkag mus rau lub cell ua kom nws tso tshuaj tiv thaiv kab mob.
