Daga ina hydroxypropyl methylcellulose ya fito?

Hydroxypropyl methylcellulose (HPMC) wani polymer roba ne wanda aka samo shi daga cellulose, wanda ke faruwa a dabi'a na kwayoyin halitta wanda ke haifar da bangon tantanin halitta.Ana yin HPMC ta hanyar sinadari mai gyara cellulose ta hanyar da ake kira etherification.

A cikin etherification, ana bi da cellulose tare da cakuda propylene oxide da methyl chloride a ƙarƙashin yanayin sarrafawa don samar da hydroxypropyl cellulose (HPC).Sannan ana ƙara gyaggyarawa HPC ta hanyar yi masa magani da methanol da hydrochloric acid don samar da HPMC.

Samfurin HPMC da aka samu shine mai narkewa mai ruwa, wanda ba na ionic polymer wanda ke da kaddarorin masu amfani da yawa, irin su babban riƙewar ruwa, iyawar ƙirƙirar fim mai kyau, da kyawawan kaddarorin haɓakawa da daidaitawa.Waɗannan kaddarorin suna sa HPMC ta zama ƙari mai amfani a cikin aikace-aikace da yawa, kamar kayan gini, magunguna, da samfuran abinci.

Yayin da aka samo HPMC daga cellulose, shi ne polymer roba wanda aka samar ta hanyar hadadden tsarin sinadarai.
