Viscosity nke HPMC dabara na ọnọdụ okpomọkụ, ya bụ, viscosity na-abawanye ka okpomọkụ na-ebelata.

HPMC ma ọ bụ hydroxypropyl methylcellulose bụ ihe eji eme ihe n'ọtụtụ ụlọ ọrụ gụnyere ọgwụ, ihe ịchọ mma na nri.A na-eji ya eme ihe n'ọtụtụ ebe dị ka thickener na emulsifier, na viscosity ya na-agbanwe dabere na okpomọkụ ọ na-ekpughere ya.N'isiokwu a, anyị ga-elekwasị anya na mmekọrịta dị n'etiti viscosity na okpomọkụ na HPMC.

HPMC sitere na cellulose, polymer na-emekarị na osisi.Iji mepụta HPMC, cellulose kwesịrị ka ejiri propylene oxide na methyl chloride gbanwee kemịkalụ.Mgbanwe a na-ebute nguzobe nke hydroxypropyl na methyl ether n'ime agbụ cellulose.Ihe si na ya pụta bụ ihe siri ike nke nwere ike ịgbaze na mmiri na ihe ndị na-emepụta ihe na-edozi ahụ ma jiri ya mee ihe n'ụdị dị iche iche, gụnyere dịka mkpuchi maka mbadamba nkume na dịka onye na-emepụta ihe oriri, n'etiti ndị ọzọ.

Viscosity nke HPMC na-adabere na ntinye nke ihe na okpomọkụ nke ekpughere ya.N'ozuzu, viscosity nke HPMC na-ebelata site na ụbara itinye uche.Nke a pụtara na mkpokọta HPMC dị elu na-ebute viscosities dị ala yana ọzọ.

Otú ọ dị, mmekọrịta dị n'etiti viscosity na okpomọkụ dị mgbagwoju anya karị.Dị ka e kwuru na mbụ, viscosity nke HPMC na-abawanye na ibelata okpomọkụ.Nke a pụtara na mgbe HPMC na-edobe okpomọkụ dị ala, ike ọ na-asọ na-ebelata, ọ na-aghọwanye viscous.N'otu aka ahụ, mgbe HPMC na-edo onwe ya n'okpuru okpomọkụ, ike ya na-asọba na-abawanye na viscosity ya na-ebelata.

Enwere ihe dị iche iche na-emetụta mmekọrịta dị n'etiti okpomọkụ na viscosity na HPMC.Dịka ọmụmaatụ, solutes ndị ọzọ dị na mmiri mmiri nwere ike imetụta viscosity, dị ka pH nke mmiri mmiri.N'ozuzu, Otú ọ dị, enwere mmekọrịta dị n'etiti viscosity na okpomọkụ na HPMC n'ihi mmetụta okpomọkụ na njikọ hydrogen na mmekọrịta molecular nke agbụ cellulose na HPMC.

Mgbe HPMC na-edobe okpomọkụ dị ala, agbụ cellulose na-esiwanye ike, nke na-eduga n'ịba ụba hydrogen bonding.Njikọ hydrogen ndị a na-eme ka ihe na-eguzogide ihe na-asọpụta, si otú ahụ na-amụba viscosity ya.N'aka nke ọzọ, mgbe HPMC nwere okpomọkụ dị elu, agbụ cellulose na-agbanwewanye nke ọma, nke mere ka njikọ hydrogen dị ntakịrị.Nke a na-ebelata ike nke ihe ahụ na-asọba, na-ebute viscosity dị ala.

Ọ dị mma ịmara na ọ bụ ezie na a na-enwekarị mmekọrịta dị n'etiti viscosity na okpomọkụ nke HPMC, nke a abụghị mgbe niile maka ụdị HPMC niile.Kpọmkwem mmekọrịta dị n'etiti viscosity na okpomọkụ nwere ike ịdịgasị iche dabere na usoro nrụpụta yana akara ọkwa HPMC ejiri.

HPMC bụ ihe na-arụ ọrụ dị iche iche ejiri mee ihe n'ọtụtụ ụlọ ọrụ dị iche iche maka ihe na-eme ka ọ sie ike na emulsifying.Viscosity nke HPMC na-adabere n'ọtụtụ ihe, gụnyere ntinye nke ihe na okpomọkụ nke ekpughere ya.N'ozuzu, viscosity nke HPMC na-adaba na okpomọkụ, nke pụtara na ka okpomọkụ na-ebelata, viscosity na-abawanye.Nke a bụ n'ihi mmetụta okpomọkụ na njikọ hydrogen na mmekọrịta molekụla nke agbụ cellulose n'ime HPMC.
