2. Nws kuj muaj qhov zoo permeability, uas tuaj yeem nkag mus ntawm cov cell membranes thiab txhawb kev nqus tshuaj.
Daim ntawv thov
1. Hauv tshuaj, DMSO tau siv dav los ua tus neeg xa tshuaj los txhawb cov tshuaj nkag mus rau ntawm daim tawv nqaij, mucosa, thiab lwm yam ntaub so ntswg. Lub zog hnyav hnyav ntawm DMSO ua kom nws txhawb txoj kev nkag mus ntawm cov tshuaj molecules los ntawm biofilms, thaum nws cov khoom me me kuj txhais tau tias nws tsis muaj qhov tsis zoo rau cov kab mob lom. Nws muaj cov nyhuv tshwj xeeb ntawm cov tshuaj tawg hauv cov ntaub so ntswg, cov hlwb, thiab txhim kho cov kev daws teeb meem los txhim kho lawv qhov nqus thiab diffusion permeability, thiab yog li siv dav hauv kev kho mob science.
2. Hauv kev tshawb fawb txog kev ua neej, DMSO tau siv dav rau kev khaws cia, khaws cia, thiab khov ntawm cov qauv tshuaj lom neeg, nrog rau hauv cov kab lis kev cai ntawm tes thiab kev sim pib. Cov khoom hnyav ntawm DMSO ua rau nws yog ib qho tseem ceeb ntawm cov cab kuj rau cov kab mob lom macromolecules, thiab nws cov kev ua kom muaj kab mob siab thiab tsis muaj tshuaj lom kuj ua rau nws siv dav hauv cell thiab microbial kab lis kev cai. Yog li ntawd, hauv kev tshawb fawb txog kev ua neej nyob, DMSO tau dhau los ua ib qho tseem ceeb ntawm cov tshuaj reagents.
3. Hauv kev lag luam chemistry, DMSO yog lub zog hnyav thiab cov tshuaj tiv thaiv nruab nrab, ua lub luag haujlwm tseem ceeb hauv cov organic synthesis thiab cov tshuaj tiv thaiv catalytic. Piv txwv li, nws yog dav siv los catalyze cyclic reactions, xws li mus ob peb vas kev xav, quaternary ammonium ntsev hloov, thiab nees lub bianny cov tshuaj tiv thaiv. Nws kuj yog siv nyob rau hauv ntau yam organic synthesis tshuaj, xws li nucleophilic hloov cov tshuaj tiv thaiv thiab condensation tshua. Tsis tas li ntawd, vim nws txoj kev daws teeb meem zoo kawg nkaus, nws kuj tau siv dav hauv kev tshuaj xyuas tshuaj los txhawb kev ntsuam xyuas ntawm cov tshuaj lom neeg ntawm cov tshuaj molecules.

FAQ
Q1: Dab tsi hnyav yog cov khoom no tshwj xeeb tshaj yog haum rau?
A: Tshwj xeeb tshaj yog nyob rau hauv acrylonitrile polymerization rau cov kuab tshuaj thiab nqus cov kuab tshuaj, polyurethane synthesis thiab nqus cov kuab tshuaj, li polyamide, polyimide thiab polysulfone resin hluavtaws hnyav, aromatics, butadiene extraction hnyav, synthesis ntawm chlorofluoraniline hnyav, acetylene, aromatics, sulfur dioxide thiab lwm yam gases. cov kuab tshuaj thiab acrylic fiber spinning hnyav.
Q2: Dab tsi yog kev ceev faj thaum siv cov khoom no?
A: DMSO muaj qee yam tshuaj lom, yog li nws yuav tsum tsis txhob muaj kev kub ntxhov thaum siv. 1%-5% dej ammonia yuav tsum tau npaj tseg, thiab daim tawv nqaij yuav tsum tau ntxuav nrog dej ntau thiab dilute ammonia dej tom qab stains.
