Otu esi atụ viscosity nke hydroxypropyl methyl cellulose

Iwuli pụrụ iche hydroxypropyl methyl cellulose iji zere mmiri infiltration na mgbidi, ga-abụ nnọọ ihe ziri ezi ego nke mmiri nwere ike ịnọ na ngwa agha simenti na-arụpụta ezi arụmọrụ na mmiri na ọrụ nke hydroxypropyl methyl cellulose na ngwa agha nwere ike nhata na viscosity, elu viscosity nke hydroxypropyl methyl cellulose njigide mmiri ga-aka mma.

Ozugbo mmiri nke hydroxypropyl methyl cellulose dị elu nke ukwuu, njide mmiri nke hydroxypropyl methyl cellulose ga-ada, ọ ga-edugakwa kpọmkwem n'ịrụ ọrụ nke hydroxypropyl methyl cellulose.Anyị na-marakwa na ihe ga-adị mfe karị imehie ihe, anyị kwesịrị ịdị na-adị ọhụrụ mgbe niile, anyị ga-enweta ihe a na-atụghị anya ya.

Viscosity pụtara ìhè bụ ndepụta dị mkpa nke hydroxypropyl methyl cellulose.Ụzọ nha a na-ejikarị bụ ntụgharị viscosity ntụgharị, nha viscosity capillary na nha viscosity ọdịda.

Na mbụ, a na-ekpebi hydroxypropyl methyl cellulose site na nha viscosity capillary, na-eji viscometer Uhnscher.Ngwọta nha na-abụkarị ngwọta mmiri nke 2, usoro a bụ: V=Kdt.V bụ viscosity na sekọnd, K bụ ihe na-adịgide adịgide nke viscometer, D bụ njupụta na okpomọkụ mgbe niile, na T bụ oge ọ na-ewe iji si n'elu gaa na ala nke viscometer na sekọnd.Ụzọ a na-arụ ọrụ dị mgbagwoju anya, ma ọ bụrụ na e nwere ihe na-adịghị edozi, ọ dị mfe ime ka njehie, ọ na-esiri ike ịmata àgwà hydroxypropyl methylcellulose.

Nsogbu nke ịmepụta gluu stratification bụ nnukwu nsogbu ndị ahịa zutere.Nke mbụ, a ga-atụle nsogbu nke akụrụngwa maka ịmepụta stratification gluu.Isi ihe mere eji wuo stratification gluu bụ enweghị nkwekọrịta n'etiti mmanya polyvinyl (PVA) na hydroxypropyl methylcellulose (HPMC).Ihe nke abụọ kpatara ya bụ na oge ngwakọta ezughị;E nwekwara ụlọ gluu ndim arụmọrụ adịghị mma.

N'ịrụ ụlọ gluu, a ga-eji ngwa ngwa hydroxypropyl methylcellulose (HPMC) mee ihe n'ihi na a na-achụsasị HPMC na mmiri ma ọ naghị agbaze n'ezie.Ihe dị ka nkeji 2, viscosity nke mmiri mmiri na-eji nwayọọ nwayọọ na-abawanye, na-eme ka colloid viscos na-egbuke egbuke.

Ngwaahịa na-ekpo ọkụ na-ekpo ọkụ, na mmiri oyi, nwere ike ịgbasa ngwa ngwa na mmiri ọkụ, na-apụ n'anya na mmiri ọkụ, mgbe okpomọkụ na-adaba na ọnọdụ okpomọkụ, viscosity ji nwayọọ nwayọọ na-apụta, ruo mgbe e guzobere transperent viscous colloid.Hydroxypropyl methylcellulose (HPMC) n'ime ụlọ gluo agbakwunyere ka akwadoro maka 2-4kg.

Hydroxypropyl methyl cellulose (HPMC) na ụlọ gluu chemical kwụsie ike, mildew, mmiri njigide mmetụta dị mma, na-adịghị emetụta PH mgbanwe, viscosity si 100 000 S - 200 000 S nwere ike iji.Ma na mmepụta abụghị nke elu viscosity dị mma, viscosity na ike nkekọ bụ inversely proportionally, elu viscosity, ike bụ obere, n'ozuzu 100,000S viscosity kwesịrị ekwesị.
