MHEC Hydroxyethyl Methyl Cellulose
CAS:9032-42-2
I-Hydroxyethyl Methyl Cellulose (MHEC) ngamanzi e-soluble nonionic cellulose ethers, anikezelwa njenge-powder ejikelezayo yamahhala okanye kwi-granular form cellulose.
I-Hydroxyethyl Methyl Cellulose (MHEC) yenziwe kwi-cotton-cellulose ecocekileyo kakhulu ngokusabela kwe-etherification phantsi kweemeko ze-alkali 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.
I-MHEC ikwabizwa ngokuba yi-HEMC, i-Methyl Hydroxyethyl Cellulose, enokusetyenziswa njenge-ejenti ephezulu yokugcina amanzi, i-stabilizer, i-adhesives kunye ne-ejenti yokwenza ifilimu ekwakhiweni, i-adhesives tile, i-samente kunye ne-gypsum based plasters, isicoci solwelo, kunye nezinye izicelo ezininzi.
