Methyl-hydroxyethylcelculose | I-CAS 9032-42-42-4

Methyl hydroxyyethylcelcellellose (Mhec) i-cellulose derivative ngefomula yamakhemikhali (c6h10o5) n. Kuthathwe ku-cellulose, i-polymer eyenzeka ngokwemvelo etholakala ezindongeni zeseli zezitshalo. I-MHEC ihlanganiswe ngokuguqulwa kwamakhemikhali kwe-cellulose, yethula amaqembu we-methylyeth kanye ne-hydroxyethyyl emgogodleni we-cellulose.

Nawa amanye amaphuzu asemqoka nge-methylyyyyethylcellellulose:

1. Isakhiwo samakhemikhali: I-MHEC i-polymer encibilikayo yamanzi enesakhiwo esifana naleso se-cellulose. Ukungezwa kwamaqembu we-methylyeth kanye ne-hydroxyethyl kunikeza izakhiwo ezihlukile ku-polymer, kufaka phakathi i-solubity ethuthukisiwe emanzini kanye nekhono elikhulisa elikhulisa.
2. Izakhiwo: I-MheC ibonisa ukuqina okuhle, ukwakha amafilimu, kanye nokubopha izakhiwo, okwenza kube lula ukuthola izicelo eziningi. Isetshenziswa kakhulu njengomuntu omkhulu, i-stabilizer, kanye ne-viscosity modifier emidlalweni ehlukahlukene, kufaka phakathi ukwakhiwa, imithi, ukunakekelwa komuntu siqu, kanye nendwangu.
3. Inombolo ye-CAS: Inombolo ye-CAS ye-methylyyyethyylcellellose ingu-9032-42-2. Izinombolo ze-Cas ziyingqayizivele yokuhlonza izinombolo ezihlukile ezabelwe izinto zamakhemikhali ukwenza lula ukukhonjwa nokulandelela ezincwadini zesayensi kanye nemininingwane yokulawula.
4. Izicelo: I-Mhec ithola ukusetshenziswa okubanzi embonini yezokwakha njenge-ejenti yokuqina odongeni olususelwa kusawokuzi, izinamathiseli ze-tile, kanye nezinto zokwenziwa ze-gypsum. Emikhakheni nemikhiqizo yokunakekelwa komuntu siqu, kusetshenziswa njenge-binder, ifilimu yangaphambili, kanye ne-viscosity modifier kuma-tablet coatings, izixazululo ze-ophthalmic, okhilimu, ama-shadoos.
5. Isimo Sokulawula: I-methyl hydroxyyethylcellulose ngokuvamile ibhekwa njengephephile (GRAS) ngokusetshenziswa kwayo okuhlosiwe ezimbonini ezahlukahlukene. Kodwa-ke, izidingo ezithile zokulawula zingahluka ngokuya ngezwe noma esifundeni sokusebenzisa. Kubalulekile ukuhambisana nemigomo nemihlahlandlela efanele lapho kwakhiwa imikhiqizo equkethe i-MHEC.

Sekukonke, i-methyl hydroxyyethylcellellulose iyindlela eguquguqukayo ye-cellulose etholwa ngezakhiwo ezibalulekile ezinhlobonhlobo zezicelo zezimboni nezentengiso. Amandla awo okuthuthukisa izakhiwo ze-mboyali zokwakheka kwenza kube yikhekhe elikhethwayo lokuthola izici zokusebenza ezifiselekayo emikhiqizweni ehlukahlukene.
