HydroxyPropylmethylcellCellCellsells (HPMC) ni urugingo rufite ibikoresho bibisi mu nganda nyinshi bitewe n'imitungo mibi. Bikunze gukoreshwa nkibiryo byongeweho, ubunini bwo kwisiga, ndetse nuburyo bwa buvuzi mumiti myinshi. Umutungo wihariye wa HPMC nimyitwarire yayo ya thixotropic, iyemerera guhindura virusi nimitungo yimiterere mubihe bimwe. Byongeye kandi, abantu benshi basukuye hamwe na vino nkeya HPMC bafite uyu mutungo, exelid thixotropy ndetse munsi yubushyuhe bwa gel.
Thixotropipy ibaho muri HPMC mugihe igisubizo gikubiye inkombe mugihe igitutu gikoreshwa cyangwa kikangurirwa, bikaviramo kugabanuka kwa vino. Iyi myitwarire irashobora kandi guhindurwa; Iyo imihangayiko ikuweho kandi igisubizo gisigaye kuruhuka, vinosity isubira buhoro buhoro igana muri leta nkuru. Uyu mutungo wihariye ukora HPMC ibice byingirakamaro munganda nyinshi nkuko bituma kuri porogaramu yoroshye no gutunganya byoroshye.
Nka hydrocolloide, hpmc yabyimbye mumazi kugirango akore gel. Urwego rwo kubyimba no kuri dolling biterwa nuburemere bwa molecular hamwe na polymer, phi nubushyuhe bwigisubizo. Ubushishozi bwo hejuru HPMC bufite uburemere bwimbitse kandi butanga gel ndende, mugihe virusi nkeya HPMC ifite uburemere buke bwa molecular kandi itanga gel nkeya. Nubwo, nubwo itandukaniro ryimikorere, ubwoko bwombi bwa mpmcs thixotropie kubera impinduka zubwibiko zibera kurwego rwa molekile.
Imyitwarire ya Thixotropic ya HPMC nigisubizo cyo guhuza iminyururu ya polymer kubera imihangayiko yogosha. Iyo imihangayiko yo kwigomeka ikoreshwa kuri HPMC, iminyururu ya polymer ihuza n'icyerekezo cy'imihangayiko ikoreshwa, bikaviramo gusenya imiyoboro itatu-imiyoboro yabayeho mu gihe hatabayeho imihangayiko. Guhagarika umuyoboro bivamo kugabanuka kwikibazo. Iyo imihangayiko ikuweho, iminyururu ya polymer yohereze mubyerekezo byambere, kubaka umuyoboro no kugarura vino.
HPMC nayo igaragaza thixotropi munsi yubushyuhe bwa dolling. Ubushyuhe bwa Gel nubushyuhe buri gihe urunigi rwa Crosmer cance kugirango ikore umuyoboro wigipimo bitatu, ugize gel. Biterwa no kwibanda, uburemere bwa molekile na ph of igisubizo cya polymer. Gel yavuyemo ifite ubushishozi bwo hejuru kandi ntabwo ihinduka vuba mugitutu. Ariko, munsi yubushyuhe bwa gelateri, igisubizo cya HPMC cyakomeje kumazi, ariko kiracyagaragaza imyitwarire ya thixotropique kubera kuboneka kumiterere yumurongo. Umuyoboro washyizweho nibice usenyuka mukibazo, bikaviramo kugabanuka kwa vino. Iyi myitwarire ifite akamaro muri porogaramu nyinshi aho ibisubizo bigomba gutemba byoroshye mugihe ubyutsa.
HPMC ni imiti itandukanye ifite imitungo myinshi yihariye, imwe murimwe muriyo ari imyitwarire yayo. Byombi-viscosity na viscosity HPMCs HPMC ifite uyu mutungo, erekana thixotropy no munsi yubushyuhe bwa gel. Ibi biranga bituma HPMC ibice byingirakamaro munganda nyinshi bisaba ibisubizo bikemura byoroshye kugirango ubike neza. Nubwo itandukaniro ryimiterere hagati ya vino-succosity hamwe na HPMCS nkeya HPMCIQUE, imyitwarire yabo ya Thixotropic ibaho kubera guhuza no guhungabanya imiterere yumurongo. Kubera imitungo yihariye, abashakashatsi bahora bakoresha porogaramu zitandukanye za HPMC, bizeye gukora ibicuruzwa bishya no gutanga ibisubizo byiza kubaguzi ku isi.
