A na-ekewa Hydroxypropyl methyl cellulose n'ụdị dị iche iche, oleekwa ihe dị iche na ojiji ya?
Enwere ike ikewa HPMC n'ụdị ngwa ngwa na ụdị agbaze ọkụ.Ngwa ngwa ngwaahịa na-agbasa ngwa ngwa na mmiri oyi wee pụọ n'ime mmiri.N'oge a, mmiri mmiri enweghị viscosity, n'ihi na HPMC na-agbasasị na mmiri na-adịghị n'ezie igbari.Mgbe ihe dị ka nkeji 2 gasịrị (na-akpali akpali), viscosity nke mmiri mmiri na-eji nwayọọ nwayọọ na-abawanye, na-eme ka colloid na-acha ọcha na-acha ọcha.Ngwaahịa na-ekpo ọkụ na-ekpo ọkụ nwere ike ịgbasa ngwa ngwa na mmiri ọkụ ma pụọ na mmiri ọkụ mgbe ha na-agbakọta na mmiri oyi.Mgbe okpomọkụ na-adaba na ọnọdụ okpomọkụ (dị ka gel okpomọkụ nke ngwaahịa), viscosity ji nwayọọ nwayọọ na-apụta ruo mgbe a na-emepụta colloid viscous transperent.
Kedu otu esi ekpe ikpe nke hydroxypropyl methyl cellulose n'ụzọ dị mfe na nke uche?
Ọcha.Ọ bụ ezie na ịcha ọcha enweghị ike ikpebi ma HPMC dị mfe iji, ma ọ bụrụ na agbakwunyere ihe ndị na-acha ọcha na usoro mmepụta, ọ ga-emetụta àgwà ya, ọtụtụ ngwaahịa dị mma nwere ezigbo ọcha.

Kedu ụzọ mgbaze nke hydroxypropyl methyl cellulose?
Enwere ike ịgbakwunye ụdị niile na ihe site na usoro ngwakọta akọrọ;
Mgbe ọ dị mkpa ka etinye ya ozugbo na ngwọta mmiri na-ekpo ọkụ na ụlọ okpomọkụ, ọ ka mma iji ụdị mgbasa ozi mmiri oyi.N'ozuzu, enwere ike ịgbanye ya n'ime nkeji 10-90 mgbe agbakwunyere (akpali)

Kedu ọrụ hydroxypropyl methyl cellulose na-arụ na ntinye nke ntụ ntụ putty, na ma enwere kemistri?
Na ntụ ntụ putty, ọ na-arụ ọrụ atọ: ịgbakọ, njigide mmiri na iwu ụlọ.Na-eto eto, cellulose nwere ike itolite, rụọ ọrụ nke nkwusioru, mee ka ngwọta ahụ dị n'otu elu na ala, ma guzogide ịda mbà n'obi.Njide mmiri: mee ka ntụ ntụ putty kpoo nwayọọ nwayọọ, ma nyere calcium lime aka imeghachi omume n'okpuru mmiri.Mwube: cellulose nwere mmetụta mmanu mmanu, nke nwere ike ime ka ntụ ntụ putty nwee ezigbo ọrụ.HPMC anaghị eso na mmeghachi omume kemịkalụ ọ bụla, mana ọ na-arụ naanị ọrụ inyeaka.
Kedu ihe jikọrọ jel okpomọkụ nke hydroxypropyl methyl cellulose?
Okpomọkụ gel nke HPMC metụtara ọdịnaya metoxyl ya.Ọdịnaya methoxyl dị ala, ọ na-abawanye okpomọkụ gel.
enwere mmekọrịta dị n'etiti mwụda ntụ ntụ na hydroxypropyl methyl cellulose?
O di mkpa!!!HPMC nwere njigide mmiri na-adịghị mma, nke ga-eme ka mfu ntụ ntụ.
Ngwa nke hydroxypropyl methyl cellulose na putty ntụ ntụ, gịnị bụ ihe kpatara egosipụta na putty ntụ ntụ?
HPMC na-arụ ọrụ atọ n'ime ntụ ntụ putty: ịgba, njigide mmiri na ihe owuwu.Ihe kpatara afụ bụ ndị a:
