Yintoni umahluko phakathi kwe-hydroxypropyl methylcelcelculose (i-HPMC) kunye okanye ngaphandle kwezi?

Hydroxypropyl methylcelculose (hpmc)Isisele esisungulwa ngokubanzi sisetyenziswe ngokubanzi kwindawo yamayeza, ukutya, iikhemikhali kunye namashishini okwakha. Isakhiwo sayo semichiza siqulathe i-hydroxylypropy kunye namaqela e-methyl, kunye nemisebenzi yayo ephambili injenge-tickener, iarhente yeGeling, inza umahluko phakathi kwencwadi ethi "I-S" imele ingcaciso kunye neepropathi.

1. Intsingiselo ye-HPMC kunye ne-HPMCS

Umahluko ophambili phakathi kwe-HPMC kunye ne-HPMCs kukuba "s" kwigama lokugqibela libonisa "iqela le-sulffar", kwezi zinto, iimeko ezithile, i-HPMC iyongeza imisebenzi yazo.

I-HPMC: Le yi-Hydroxypropyl Methylcelceluplose, engabinamaqela e-sulfate. Iqhelekile isetyenziselwa ukutya, amayeza, amayeza, ukwakhiwa kunye nezinye iinkalo, kwaye unazo iipropathi ezisisiseko ezinjengokutyibilika, ukubekwa kwefilimu, kunye nokusasazwa. I-HPMC yindibaniselwano ye-hydroxylypropy kunye namaqela e-methyl, kunye nohlobo lwayo, ukuluka kunye neRheemology kungalawulwa ngokuhlengahlengiswa kweedigri ezahlukeneyo ze-etheriya.

I-HPMCS: I-HPMCs yi-hydroxypropyl methylcelcelgalose i-sulfate yamaqela e-sulfate. "I-s" imele inkqubo ye-sulffition, edla ngokwenza into ngakumbi i-hydrophilic, kunye nokuzinza kunye nokubonisa isisombululo kunokwahluka. Ii-HPMCs zihlala zisetyenziswa kwiimeko ezifuna uzinzo oluphezulu kunye nokuhlawulwa okuthile kwemichiza, ezinjengendawo yamayeza.

2. Umahluko wamachiza amachiza

Isakhiwo sekhemikhali se-HPMC sisekwe ikakhulu kwi-seluplose, eguqulwa yi-methytration kunye ne-hydroxyypropy. Isakhiwo sayo sinomhlaba ophakamileyo wamanzi kwaye inokwenza isisombululo se-colloidal emanzini.

Isakhiwo sekhemikhali se-HPMCS sisekwe kwi-HPMC ngokusungulwa kwamaqela e-sulfate, etshintsha i-hydrophicicity kunye nokusebenza kwezisombululo ziqingqiweyo zamanzi. Ukuqaliswa kwamaqela e-rulfate kunceda ukwandisa i-hydration yayo kwaye kunokuchaphazela ireyithi yayo yokuchithwa okanye iipropathi ze-suheological phantsi kweemeko ezithile.

3. Umahluko wentsebenzo

Ukuluka: i-HPMC ihlala inyibilika emanzini ukwenza isisombululo se-viscous kwaye inohlengahlengiso oluhle lokufakwa. Ukuqina kwayo kunye nokuncamathiswa kunokulungiswa njengoko kufuneka, njengokulawula ulwalamano lwamanzi kunye neepropathi zeRhemoology eziboniswe kwizisombululo ezahlukeneyo.

Uzinzo: I-HPMCS inyukele i-hydrophicicity ngenxa yokwazisa amaqela e-sulfate, enokuthi ibonelele ngokuzinza okungcono kwezinye iimveliso zamayeza okanye zempahla. Ukongeza, amaqela e-sulffate anokwenza i-kimbacell®HPMcs azinzileyo phantsi kweemeko ezithile, njengokufuma okuphezulu okanye i-HPMCS eguqukayo, apho i-HPMCS ibonisa ukunyamezelana okuqinileyo.

I-biomatisise-promomatining: Njengombono osetyenzisiweyo osetyenzisiweyo, i-HPMC iqinisekisiwe ngokupheleleyo nge-biomatisiatication kunye nokhuseleko kwintsimi yamayeza. Nangona kunjalo, ngenxa yokongezwa kwamaqela e-sulfate, i-HPMCS inokufuna izifundo ezongeziweyo zetyhefu kwizicelo ezithile ezibuthathaka.

4. Amasimi esetyenziswayo

I-HPMC: isetyenziswa ngokubanzi kwiindawo zamachiza (ezinje ngamachiza okukhulula, iitafile zetafile), i-cosmetings, yokwakhiwa, ukwakhiwa, ukutya, ukutya kunye namanye amashishini. I-non-bubyuli, i-hypoalgenicgenity kunye ne-biompatifayisi ye-biomative iyenza ibe yinto eqhelekileyo, ifilimu yangaphambili kunye nendawo yokuziqhelanisa namashishini amayeza kunye nokutya.

I-HPMCcs: Ngenxa yepropathi yayo ekhethekileyo kunye neempawu ze-solbing, ii-HPMCs zisetyenziswa kakhulu kwezinye izinto ezifuna izinto ezenziwa ngamayeza, ngakumbi ukulungiswa kweziyobisi ezinzileyo. I-HPMCS ihlala isetyenziswa kwiiarhente zokukhupha iziyobisi kunye neenkqubo ezithile zokuhambisa iziyobisi, kwaye ngamanye amaxesha zisetyenziswa kwizinto zokongeza ukutya.

5. Inkcazo eqhelekileyo yemveliso

I-HPMC kunye nee-HPMCs zinoluhlu olubanzi lweenkcazo zemveliso, ezihlala zihlelwa ngokwemilinganiselo efana nobunzima bemolekyuli, inqanaba le-etheriya, kunye nokuluka. Iimveliso ezichaziweyo ezahlukeneyo ziya kubonisa ukusebenza okwahlukileyo kwizicelo ezahlukeneyo.

I-HPMC inedigri eyahlukeneyo ye-ether, i-viscofisies eyahlukeneyo kunye nezigaba, kwaye ilungele amasimi awahlukeneyo. Iinkcazo eziqhelekileyo zibandakanya i-viscofity ephantsi, viscosity eziphakathi, i-viscofity ephezulu, njl.

Inkcazo yee-HPMCs ihlulekile ngokweeparameter ezifana nenqanaba le-sulfotion, isoba kunye ne-hydrophicicity. I-HPMCS yenkcazo eyahlukileyo inokuhlengahlengiswa ngokweemfuno ezahlukeneyo zokuqulunqwa kweziyobisi.

I-HPMC kunye nee-HPMCs zinemahluko obonakalayo kwimo yemichiza, ukusebenza kunye neendawo zesicelo. I-HPMC yi-Hydroxypropyl Methylceltulose, esetyenziswe ngokubanzi kumasimi amaninzi; Ngelixa i-HPMCs yi-kimbacell ye-kimbacell®hpmc, enokusebenza okuphezulu, kwaye isetyenziswa kakhulu kwimihlaba yobungcali efuna ukukhululwa okuphezulu.

Ngokwenene ukusetyenziswa, ukhetho lweI-HPMCokanye ii-HPMCs kufuneka zigqitywe ngokweemfuno ezithile kunye nezicelo. Ukuba kukho iimfuno ezizodwa zokomelela, uzinzo, njl njl., I-HPMSS inokunikwa kuqala. Ukuba akukho zifungolo ziphezulu zeendleko kunye ne-HPMC luhlobo oluqhelekileyo noloqoqosho.
