Hydroxypropylmethylcellulose (HPMC) bụ mmepụta cellulose nke a na-ejikarị emepụta ngwaahịa dị iche iche, gụnyere mmiri mmiri ịsa efere.Ọ na-eme dị ka a vasatail thickener, na-enye viscosity na nkwụsi ike na mmiri formulations.
Nyocha HPMC:
HPMC bụ a sịntetik mgbanwe nke cellulose, a eke polima dị na osisi cell mgbidi.A na-emepụta ya site n'ịgbanwe cellulose nke ọma site na iji propylene oxide na methyl chloride.Ngwaahịa a na-esi na ya pụta bụ polymer na-agbaze mmiri nwere ihe pụrụ iche rheological.
Ọrụ HPMC na mmiri mmiri ịsa efere:
Njikwa viscosity: Otu n'ime isi ọrụ HPMC na mmiri ịsa efere bụ ijikwa viscosity.Ọ na-enye mmiri mmiri ahụ ụfọdụ na-agbanwe agbanwe, na-eme ka ọdịdị ya dị elu na nhazi ya.Nke a dị mkpa iji hụ na onye na-ehicha ihe na-anọgide na-adị n'elu ma na-ewepụ griiz na unyi nke ọma.
Nkwụsi ike: HPMC na-akwalite nkwụsi ike nhazi site na igbochi nkewa oge na mmiri ozuzo.Ọ na-enyere aka idobe ngwaahịa ahụ otu ma kwụsie ike ka oge na-aga, na-ahụ na arụmọrụ na-agbanwe agbanwe.
Ọfụfụ emelitere: Na mgbakwunye na mmetụta ọ na-arị elu, HPMC na-enyekwa aka melite njirimara ịfụfụ nke mmiri ịsa efere.Ọ na-enyere aka ịmepụta ụfụfụ kwụsiri ike nke na-enyere aka n'usoro nhicha site na ọnyà na iwepụ unyi na unyi.
Ndakọrịta na surfactants: Mmiri mmiri na-asa efere nwere ihe ndị na-emepụta ihe, nke dị mkpa maka ịkụda griiz.HPMC dakọtara na ụdị surfactants dị iche iche, na-eme ka ọ bụrụ ihe siri ike maka usoro ndị a.
Ihe gbasara gburugburu ebe obibi: A na-ahụta HPMC dị ka enyi na gburugburu ebe obibi yana nchekwa maka iji na ngwaahịa ụlọ.Ọ bụ ihe na-emebi emebi na ọ dịghị etinye nnukwu ihe egwu na ahụike mmadụ ma ọ bụ gburugburu ebe obibi.
Ngwa na usoro:
A na-agbakwunye HPMC na nhazi mmiri ịsa efere mgbe a na-emepụta ihe.Ọnụ ego HPMC ejiri mee ihe dabere na viscosity achọrọ yana ihe ndị ọzọ akọwapụtara nke ngwaahịa ahụ.Ndị na-emepụta ihe na-atụle ihe ndị dị ka ụdị surfactant na ntinye uche, ọkwa pH, na ihe mgbaru ọsọ arụmọrụ zuru ezu.
Hydroxypropyl methylcellulose (HPMC) na-arụ ọrụ dị mkpa dị ka onye na-agbapụta mmiri na-asa efere, na-enye njikwa viscosity, nkwụsi ike na mma ịfụfụ.Ndakọrịta ya na surfactants na ịdị mma gburugburu ebe obibi na-eme ka ọ bụrụ nhọrọ a ma ama na nhazi ngwaahịa nhicha ụlọ.
