Banyere nsogbu nke gel okpomọkụ nke hydroxypropyl methylcellulose HPMC, ọtụtụ ndị ọrụ adịkarịghị etinye uche na nsogbu nke jel okpomọkụ nke hydroxypropyl methylcellulose. N'oge a, a na-ahụkarị hydroxypropyl methylcellulose dị ka viscosity si dị, mana maka ụfọdụ gburugburu pụrụ iche na ụlọ ọrụ pụrụ iche, ezughị ezu iji gosipụta viscosity nke ngwaahịa ahụ. Ihe na-esonụ na-ewebata obere oge jel okpomọkụ nke hydroxypropyl methylcellulose.
Ọnụ ọgụgụ nke methoxyl na-ejikọta kpọmkwem na ogo nke cellulose sourization, na ọdịnaya nke metxyl otu nwere ike gbanwee site na ịchịkwa usoro, mmeghachi omume okpomọkụ na oge mmeghachi omume. N'otu oge ahụ, ogo inactivation na-emetụta ogo nke nnọchi nke hydroxyethyl ma ọ bụ hydroxypropyl. Ya mere, njigide mmiri nke cellulose ether na oke gel okpomọkụ ga-adị njọ. Ọ dị mkpa ka a nyochaa usoro mmepụta a, n'ihi ya, ọ bụghị na mmepụta nke cellulose ether dị ala ma ọ bụrụ na ọdịnaya methoxy dị ala, n'ụzọ megidere nke ahụ, ọnụahịa ahụ ga-adị elu.
A na-ekpebi ọnọdụ okpomọkụ gel site na otu metoxyl, na njigide mmiri na-ekpebi otu hydroxypropoxyl. Enwere naanị otu atọ nwere ike dochie anya na cellulose. Chọta ọnọdụ okpomọkụ gị kwesịrị ekwesị, njide mmiri kwesịrị ekwesị, wee chọpụta ihe nlereanya nke cellulose a.
Okpomọkụ gel bụ isi ihe dị mkpa maka ntinye cellulose ether. Mgbe ọnọdụ okpomọkụ dị n'ime ya karịrị gel okpomọkụ, a ga-ekewapụ cellulose ether na mmiri ma tụfuo njide mmiri ya. The gel okpomọkụ nke cellulose ether na ahịa nwere ike ihu ọma gboo mkpa nke ngwa agha gburugburu ebe obibi (ma e wezụga maka pụrụ iche gburugburu). Mgbe ị na-etinye ngwa agha, ọ dịghị mkpa ịṅa ntị pụrụ iche na ntinye ọrụ nke okpomọkụ gel.
