Dab tsi yog DMF hauv lub desiccant? Vim li cas' t nws muaj DMF? Raws li Dingxing desiccant, DMF yog tus tsiaj ntawv luv ntawm (dimethyl fumarate). Nws feem ntau yog siv tshuaj tua kab mob thiab tshuaj tua kab mob, thiab feem ntau siv rau hauv kev tsim khoom, kev khaws cia thiab kev thauj mus los ntawm tawv, khau, ntaub, thiab lwm yam. Txawm li cas los xij, European Union tau ua tiav cov ntawv ceeb toom ntau yam ntawm daim tawv nqaij ua xua, mob eczema, tawm pob thiab kub hnyiab los ntawm cov neeg siv khoom' kis rau nkawm khau thiab tawv sofas uas muaj cov dimethyl fumarate, uas tau nyiam mloog dav. Lub koomhaum tseem ceeb hauv European Union tseem tau tshawb nrhiav thiab tshawb xyuas txij thaum ntawd, thiab tau pom zoo cov lus pom zoo los ntawm "lees tias cov neeg siv khoom muaj dimethyl fumarate yuav tsis muab tso rau hauv cov khw European", uas pib siv txij thaum Lub Tsib Hlis 1, 2009.
DMF: Nws muaj cov yam ntxwv ntawm kev tsis muaj tshuaj lom (LD_ (50) 2240 mg / kg ntawm qhov ncauj hauv nas), kev ua haujlwm siab thiab dav-pom cov kab mob tua, thiab muaj qhov tshwj xeeb tua cov pwm. Nws tuaj yeem siv los tiv thaiv pwm nyob hauv khob cij, pub mov, tshuaj pleev ib ce, ntses, nqaij, zaub thiab txiv hmab txiv ntoo. Cov tshuaj tiv thaiv pwm ntawm DMF rau lub khob cij ua tau zoo dua li cov calcium calcium propionate. Raws li kev tshawb fawb hauv tsev, DMF muaj lub peev xwm zoo antifungal, thiab nws cov txiaj ntsig antifungal ntawm kev pub noj yog qhov zoo dua li cov kua qaub ua kom zoo li propionate, sorbic acid thiab benzoic acid. Nws tuaj yeem tiv thaiv ntau yam pwm thiab kab mob hauv PDA qhov nruab nrab muaj 500-800 ppm. Tab sis EU txoj kev xav rau DMF: Lub Ib Hlis 29, 2009, EU cov tswvcuab tau pom zoo cov kev cai lij choj hais txog "kev lees paub tias cov neeg siv khoom muaj dimethyl fumarate yuav tsis muab tso rau hauv cov European ua lag luam", uas tau pib siv txij lub Tsib Hlis 1, 2009. Cov ntawv sau meej meej tshaj tawm tias yog cov ntsiab lus ntawm dimethyl fumarate hauv cov khoom lag luam lossis nws cov khoom tau siab tshaj 0.1 mg / kg, lossis cov khoom nws tus kheej tau tshaj tawm nws cov ntsiab lus ntawm dimethyl fumarate, nws yuav raug suav hais tias yog" muaj cov fumarate" Dimethyl" cov khoom yuav raug txwv tsis pub nkag mus hauv EU ua lag luam rau ncig thiab muag khoom.
Yog li no, yog tias cov neeg tsim khoom tso tawm xav xa tawm mus rau Tebchaws Europe thiab lwm qhov chaw, nws yuav tsum yog desiccant uas tsis muaj DMF. Cov desiccants uas ua los ntawm peb lub tuam txhab tsis muaj DMF, dhau qhov kev xeem RHOS, thiab ua tau raws li cov qauv European thiab Asmeskas cov qauv kev xa tawm.
