I-HPMC

I-HPMC, ekwabizwa ngokuba yi-hydroxypropyl methylcelcelgalose, yi-polymer ye-polymer esetyenziswe ngokubanzi kwi-cosmetic, kumashishini amayeza kunye nokutya. I-polymer ithathwe kwi-sellyulose, into yendalo efumaneka kwizityalo. I-HPMC yeyona nto ibalaseleyo i-chickener isetyenziselwa ukwandisa i-viscofity yezisombululo ezahlukeneyo. Amandla ayo okuvelisa i-thletropic ye-thletropic ikwenzela ukhetho oludumileyo kwizicelo ezininzi.

Iipropathi ezinkulu ze-HPMC

Iipropathi ezinkulu ze-HPMC ziyaziwa kakhulu kwishishini. I-HPMC inokunyusa i-viscofity yesisombululo ngokwenza inethiwekhi yejeyi egibisela iimolekyuli zamanzi. Amasuntswana e-HPMC ayenza inethiwekhi yejeyi xa ihlelo emanzini kwaye itsalelane nge-hydrogen. Inethiwekhi idala i-matrix eyonyusa i-vintassity yesisombululo.

Esona sibonelelo siphambili sokusebenzisa i-HPMC njenge-thi choner kukuba inokuzikhulula isisombululo ngaphandle kokuchaphazela ukucaca okanye umbala. I-HPMC yi-polymer engeyiyo i-ionic, oko kuthetha ukuba ayisebenzi nasiphi na isisombululo. Oku kwenza ukuba ilungele ukusetyenziswa kwifomu ecacileyo okanye engabonakaliyo.

Elinye i-HPMC kukuba inokuziqhelanisa nezisombululo ezisezantsi. Oku kuthetha ukuba kuphela yimali encinci ye-HPMC iyafuneka ukufezekisa i-viscofity oyifunayo. Oku kungagcina iindleko zabavelisi kwaye banike abathengi ngeemveliso zoqoqosho ngakumbi.

I-Thixotropy ye-HPMC

I-Thixotropy yipropathi yezinto zokuncipha kwi-viscosity xa iphantsi koxinzelelo lwe-Shear kwaye ibuyele kwi-viscosity yayo yoqobo xa uxinzelelo lususiwe. I-HPMC yindawo yeThixitRootropic, ethetha ukuba isasaza okanye ithulu thuls phantsi koxinzelelo lwe-Shear. Nangona kunjalo, kanye xa uxinzelelo lususiwe, ibuyela ekutsaleni nasezi-trickens kwakhona.

Iipropathi zeThixitropic ze-HPMC zenza ukuba zilungele ukusetyenziswa kwezicelo ezininzi. Umzekelo, iqhele ukusetyenziswa kwipeyinti, njengengubo enkulu kumphezulu. Iipropathi zeThixiitropic ze-HPMC ziqinisekisa ukuba ukungqengqa kuhlala kusendaweni ngaphandle kokungena okanye ukusebenza. I-HPMC ikwasetyenziswa kumzi-mveliso wokutya njenge-thickener kwiisosi kunye nokunxiba. Iipropathi zeThixitropic ze-HPMC ziqinisekisa ukuba iisosi okanye i-rocks ayikhuphuki kwii-spons okanye iipleyiti, kodwa endaweni yoko kuhlala kungaguquki.

I-HPMC yi-polymer eguquguqukayo ngezicelo ezininzi kumashishini ahlukeneyo. Iipropathi zayo zokuthambisa kunye neepropathi zeThixitropic zenza ukuba kubelinde i-cosmetic, i-chimersecial kunye nokutya. I-HPMC yeyona tyaba elibalaseleyo, inyusa ukugcinwa kwesisombululo ngaphandle kokuchaphazela ukucaca okanye umbala. Iipropathi zayo zeThixitropic ziqinisekisa ukuba isisombululo singabi kakhulu okanye sinciphile kakhulu, kuxhomekeka kwisicelo. I-HPMC sisithako esibalulekileyo kwiimveliso ezininzi, kwaye izibonelelo zayo ezininzi zenza ukuba kuthathwe ukuba kuthanda abavelisi abavelisi kunye nabathengi.
