Umahluko phakathi kwe-HPMC kunye ne-hec

Zombini i-hydroxypropyl methylcelceluplose ne hydroxyythy seluplose yisellulose, nguwuphi umahluko phakathi kwezi zimbini?

"Umahluko phakathi kwe-HPMC kunye ne-hec"

01 I-HPMC kunye ne-hec
Hydroxypropyl methylcelcelculose (hypromellose), ekwabizwa ngokuba yi-hypromellose, luhlobo lwe-ionic se-ionsulose exubeneyo. Yinto ye-semidiyo, engasebenziyo, i-viclaelastic polymer isetyenziswa njengeoyile kwi-Opthalmology, okanye njengomculo okanye imoto kumayeza omlomo.
I-HYDROXYETYL ILINOse (hec), ifomula yekhemicamiki (C2H6O2) N, i-biblene emhlophe okanye i-powylene oxide (okanye i-chibyhanol) ilungiselelwe ii-thesupic kwaye zezona-i-ionic selsulose inyibilikisi. Kuba i-HCC inepropathi elungileyo yokutyibilika, ukusasaza, ukusasaza, ukwenziwa, ukubekwa komswakali, ipeyinti, i-TORTE, izinga le-polymer ≥ 99%.

02 umahluko
Nangona zombini zisellese, kukho umahluko omkhulu phakathi kwezi zimbini:
I-Hydroxypropyl MethylcelceLcelose kunye ne-hydroxyEthlcelcelgalose yahlukile kwiPropathi, isebenzisa, kunye nokuluka.

1. Iimpawu ezahlukeneyo
I-HYDROXYPPOPLL Methylcelcelgulose: Yinto engu-semi-syntatic engafunekiyo ye-viscoestic.
I-HYDROXYETHLTELCELXEXAse: I-E-DEEERIDE NGU-ALKALIINE SeLULUse nase-Ebanone Oxide (okanye i-chlorohydrin). Yenzelwe i-ionic ye-unic foyle i-ether.

I-2. Ukuzalwa ngokwahlukileyo
Hydroxypropyl methylcelceluplose: phantse i-sullineuled kwi-eshanol ye-eshanol, i-ether ne-acetone. Sula okanye ucoceke kancinci isisombululo se-colloidal isisombululo esinyibilikisiwe emanzini abandayo.
I-HydroxyEtheetheetheetheethl seluplose: Inepropathi yokutyibilika, ukumiswa, ukubopha, ukuqina, ukusasaza kunye nokunyathela. Ingalungiselela izisombululo kwii-vings ezahlukeneyo kwaye inomoya ogqwesileyo wenkunkuma.
I-HydroxyPOpyl Methylcelceltulose ineempawu zobuchule bokuthathwa, ukunganyangeki kwetyuwa, ukuzinza kwamanzi, ukuzinza kwefilimu, ukunyangwa kweefilimu, ukusasazeka kunye nokusasazeka.

Kukho umahluko omkhulu phakathi kwezi zimbini, kwaye ukubaluleka kwazo kwimveliso kwahluke kakhulu.

I-HydroxyPOpyl Methylcelcelcelose isetyenziswa kakhulu njenge-tickener, isisasazi kunye nokuzinzisa kumzi-mveliso wokudimaza, kwaye inesifo esihle emanzini okanye izinyibilikisi ezifanelekileyo. Kumzi-mveliso wokwakha, inokusetyenziswa kwisamente, i-gypsum, i-teex potty, udaka, njl njl.
I-HydroxyEtheetheetheetheetheetheetheetheetheetheetheetheetheetheethl ineepropathi zokutsalwa, ukumiswa, ukubopha, ukuqina, ukusasaza kunye nokunyathela. Ingalungiselela izisombululo kwii-vings ezahlukeneyo kwaye inomoya ogqwesileyo wenkunkuma. I-HydroxyEtheetheetheetheetheetheetheetheetheetheethl seluplose yifilimu esebenzayo, i-tackimier, i-tickener, i-stickener kunye nokusasazwa kweenwele, i-spielines, i-cosmetics kunye ne-cosmetics; Ekuhambeni i-powders embindini luhlobo lwearhente yokuguqula i-Dull. I-HydroxyEtheetheetheetheetheetheetheetheetheetheetheetheeseyl inyibiliki ngokukhawuleza kwiqondo lokushisa eliphezulu, elinokukhawulezisa inkqubo yemveliso kunye nokuphucula ukusebenza kwemveliso. Inqaku elibonakalayo lezitolo eziqukethe i-hydroxythyl yeyokuba inokuphucula ukugungqa kunye nokuxhamla kweendwangu.
