MHEC Hydroxyethyl Methyl Cellulose

Intshayelelo

I-CAS: 9032-42-2I-Hydroxyethyl Methyl Cellulose (MHEC) ngamanzi e-soluble nonionic cellulose ethers, anikezelwa njenge-powder ehambayo yamahhala okanye kwi-granular form cellulose.I-Hydroxyethyl Methyl Cellulose (MHEC) yenziwe kwi-cotton cellulose ecocekileyo kakhulu ngokuphendula kwe-etherification phantsi kweemeko ze-alkaline ngaphandle kwamalungu ezilwanyana, amanqatha kunye nezinye izinto eziphilayo.Ibonakaliswa yi-hygroscopicity kwaye ayinakunyibilika kumanzi ashushu, i-acetone, i-ethanol kunye ne-toluene.Emanzini abandayo i-MHEC iya kuvuvukala kwisisombululo se-colloidal kwaye i-solybility yayo ayichaphazeli ixabiso le-PH.Efana ne-methyl cellulose ngelixa yongezwa kumaqela e-Hdroxyethyl.I-MHEC ixhathisa ngakumbi kwi-saline, i-soluble ngokulula emanzini kwaye inobushushu obuphezulu be-gel.MHEC yaziwa nangokuthi yi-HEMC, i-Methyl Hydroxyethyl Cellulose, engasetyenziselwa njenge-agent ephezulu yokugcina amanzi, i-stabilizer, i-adhesives kunye ne-agent-forming agent ekwakheni, izinto zokuncamathelisa iithayile, isamente kunye neplastikhi esekwe kwigypsum, isicoci solwelo, kunye nezinye iinkqubo ezininzi.
