CAS Nr .: 9032-42-2
Hydroxyethyl Methyl Cellulose (MHEC) yog cov dej soluble nonionic cellulose ethers, uas muaj pub dawb ntws hmoov los yog hauv daim ntawv granular cellulose.
Hydroxyethyl Methyl Cellulose (MHEC) yog tsim los ntawm cov ntshiab ntshiab paj rwb-cellulose los ntawm cov tshuaj tiv thaiv ntawm etherification nyob rau hauv alkaline tej yam kev mob yam tsis muaj lub cev ntawm cov tsiaj, rog thiab lwm yam bioactive constituents.MHEC zoo nkaus li cov hmoov dawb thiab tsis muaj ntxhiab thiab tasteless.Nws yog featured los ntawm hygroscopicity thiab hardly soluble nyob rau hauv dej kub, acetone, ethanol thiab toluene.Hauv dej txias MHEC yuav o mus rau hauv cov tshuaj colloidal thiab nws cov solybility tsis cuam tshuam los ntawm PH tus nqi.Zoo li methyl cellulose thaum ntxiv rau Hdroxyethyl pawg.MHEC tiv taus ntau dua rau saline, yooj yim soluble hauv dej thiab muaj gel kub dua.
MHEC tseem hu ua HEMC, Methyl Hydroxyethyl Cellulose, uas tuaj yeem siv los ua tus neeg saib xyuas dej kom ruaj khov, ruaj khov, nplaum thiab ua yeeb yaj kiab hauv kev tsim kho, pobzeb adhesives, cement thiab gypsum raws li plasters, kua xab npum, thiab ntau lwm yam kev siv.
