Ibakala lemihla ngemihla lekhemikhali i-hydroxypropyl methylcellulose yipolymer eyenziwe ngeselulosi yendalo ngokuguqulwa kweekhemikhali.I-ether ye-cellulose iphuma kwi-cellulose yendalo.Ukuveliswa kwe-cellulose ether kuyahluka kwiipolymers zokwenziwa.Izinto zayo ezisisiseko ziyi-cellulose, i-polymer compound yendalo.
Ngenxa yobungcali besakhiwo se-cellulose yendalo, i-cellulose ngokwayo ayinakukwazi ukusabela kunye nee-etherification agents.Nangona kunjalo, emva kokunyangwa kwe-ejenti yokuvuvukala, iibhondi ze-hydrogen ezinamandla phakathi kwamatyathanga e-molecular kunye namatyathanga atshatyalaliswa, kwaye ukukhutshwa okusebenzayo kweqela le-hydroxyl kuba yi-alkali cellulose esebenzayo.Emva kokusabela kwe-etherifying agent, iqela -OH liguqulwa libe yi-OR iqela Fumana i-ether cellulose.I-200,000-viscosity hydroxypropyl methylcellulose ye-"Max" ibakala lemichiza yemihla ngemihla imhlophe okanye i-powder ephuzi kancinane, engenavumba, ingenancasa kwaye ayinayo ityhefu.Inokunyibilika emanzini abandayo kunye ne-solvent edibeneyo yezinto eziphilayo ukwenza isisombululo esicacileyo se-viscous.
Ulwelo lokusetyenziswa kwamanzi lunomsebenzi ongaphezulu, ukukhanya okuphezulu, ukuzinza okuqinileyo, kwaye akuchaphazeli i-pH xa inyibilika emanzini.Ineziphumo ezityebileyo kunye ne-antifreeze kwiishampu kunye neegels zeshawa, kwaye inokugcinwa kwamanzi kunye neempawu ezilungileyo zokwenza ifilimu yeenwele kunye nolusu.Ngokunyuka okubukhali kwezinto ezisisiseko, ukusetyenziswa kweselulosi (antifreeze thickener) kwishampu kunye nejeli yeshawa kunokunciphisa kakhulu iindleko kwaye kufezekiswe umphumo oyifunayo.
