Iri na asatọ, hydroxypropyl methyl cellulose na MC kedu ihe dị iche:
MC bụ methylcellulose, nke ejiri owu a nụchara anụcha mgbe ọgwụgwọ alkali gasịrị na methane chloride dị ka onye na-ahụ maka etherification site na usoro mmeghachi omume iji mee cellulose ether. N'ozuzu, ogo nke nnọchi bụ 1.6-2.0, na solubility nke ogo dị iche iche nke nnọchi dị iche iche, nke bụ nke na-abụghị ionic cellulose ether.
(1) Njide mmiri nke methyl cellulose na-adabere na ego nke mgbakwunye ya, viscosity, urughuru mma na mgbasa ọsọ. N'ozuzu, ọ bụrụ na ọnụ ọgụgụ nke ịgbakwunye buru ibu, ịdị mma dị ntakịrị na viscosity dị ukwuu, ọnụ ọgụgụ njide mmiri dị elu. Ọnụ ọgụgụ nke agbakwunyere nwere mmetụta dị ukwuu na njide mmiri, na viscosity adịghị emetụta ọnụ ọgụgụ njide mmiri. Mgbasa ọsọ tumadi dabere na elu mgbanwe ogo nke cellulose ahụ na urughuru fineness. N'elu cellulose ether methyl cellulose na hydroxypropyl methyl cellulose ọnụ ọgụgụ njide mmiri dị elu.
(2) Methyl cellulose nwere ike etisasịwo na mmiri oyi, mmiri ọkụ mgbasa ga-ezute ihe isi ike, ya aqueous ngwọta na nso nke pH = 3-12 bụ nnọọ ike, na starch, na ọtụtụ surfactant ndakọrịta dị mma, mgbe okpomọkụ ruru na Gelation okpomọkụ, Gelation phenomen ga-eme.
(3) Mgbanwe nke okpomọkụ ga-emetụta n'ụzọ dị ukwuu na njigide mmiri nke methyl cellulose, n'ozuzu ka okpomọkụ dị elu, nke ka njọ nke njide mmiri. Ọ bụrụ na okpomọkụ nke ngwa agha gafere ogo 40, njide mmiri nke methyl cellulose ga-akawanye njọ, na-emetụta nrụnye ngwa ngwa.
(4) Methyl cellulose nwere mmetụta doro anya na owuwu na nrapado nke ngwa agha. N'ebe a, adhesion na-ezo aka na ike nrapado chere n'etiti ngwá ọrụ daub nke ndị ọrụ na mgbidi mgbidi, ya bụ, nkwụsị nke ngwa agha. Ngwongwo nrapado buru ibu, ihe mgbochi nke ngwa agha buru ibu, na ike nke ndị ọrụ na-arụ ọrụ na-arụ ọrụ na-arụkwa ọrụ buru ibu, ya mere ihe eji arụ ọrụ nke ngwa agha adịghị mma.
