IHydroxypropyl methylcellulose iyi-ether engeyona ionic cellulose eyenziwe nge-cellulose yezinto ze-polymer yemvelo ngochungechunge lwezinqubo zamakhemikhali.Ziwuhlobo lwempushana emhlophe engenaphunga, engenaphunga, engenabuthi, evuvukala emanzini abandayo futhi ibizwa ngesixazululo se-colloidal esicacile noma esinamafu kancane.Inezici zokuqina, ukubopha, ukusabalalisa, i-emulsifying, ifilimu-forming, ukumiswa, i-adsorbing, i-gelling, i-surface esebenzayo, ukugcina umswakama nokuvikela i-colloid.
I-hydroxypropyl methylcellulose enhle kakhulu ingaxazulula ngokuphumelelayo inkinga yokugcinwa kwamanzi ngaphansi kwezinga lokushisa eliphezulu.Ezikhathini zokushisa okuphezulu, ikakhulukazi ezindaweni ezishisayo nezomile kanye nokwakhiwa kongqimba oluncane ohlangothini olushisayo, i-HPMC hydroxypropyl methylcellulose yekhwalithi ephezulu iyadingeka ukuze kuthuthukiswe ukugcinwa kwamanzi odaka.
Ikhwalithi ephezulu ye-hydroxypropyl methylcellulose inokufana okuhle kakhulu.Amaqembu ayo e-methoxy ne-hydroxypropoxy asatshalaliswa ngokulinganayo eduze kweketango lamangqamuzana e-cellulose, elingathuthukisa ama-athomu omoya-mpilo ku-hydroxyl ne-ether bond kanye nenhlangano yamanzi.Ikhono lokuhlanganisa nokwenza amabhondi e-hydrogen aphendulela amanzi amahhala abe amanzi abophekile, ngaleyo ndlela alawule ngempumelelo ukuhwamuka kwamanzi okubangelwa izinga lokushisa eliphezulu kanye nokuzuza ukugcinwa kwamanzi okuphezulu.
