IHydroxypropyl Methylcellulose (HPMC) isetyenziswa ngokubanzi kwikhompawundi yepolymer, isetyenziswa ikakhulu kumayeza, ukutya, ukwakhiwa kunye nezithambiso.
1. I-Thickener kunye ne-stabilizer
I-HPMC yi-thickener esebenzayo kunye nokuzinzisa oko kunokunyusa i-viscosity yesisombululo okanye ukumiswa. Isetyenziswa ngokubanzi ekutyeni nakwizinto zokuthambisa ukunceda ukuphucula ukuthungwa kunye nokuzinza kwemveliso. Ngokomzekelo, kwishishini lokutya, i-HPMC ingasetyenziselwa njenge-thickener yejusi, i-condiments kunye ne-ayisikrimu ukuqinisekisa ukuhambelana kunye nencasa yemveliso.
2. I-Gelling kunye nokwakhiwa kwefilimu
I-HPMC inobuchule obuhle be-gelling kunye neempawu zokwenza ifilimu. Iyakwazi ukwenza i-colloid efanayo kwisisombululo okanye yenza ifilimu eqinile emva kokumisa. Le propati yenza i-HPMC ibe luncedo ngakumbi kumalungiselelo amayeza afana neepilisi kunye ne-capsules kuba inokunceda ukulawula izinga lokukhutshwa kwechiza kunye nokuphucula uzinzo lwechiza.
3. Ukunyibilika kwamanzi
I-HPMC yipolymer enyibilikayo emanzini enokunyibilika emanzini ukwenza isisombululo se-colloidal esicacileyo. Oku kwenza kube luncedo kakhulu kwizicelo ezininzi, ezifana ne-thickener kunye nokugcinwa kwamanzi kwizinto zokwakha (ezifana nodaka lwesamente), kunceda ukuphucula ukusebenza kokwakhiwa kunye nokuphucula ukuqina kwezinto.
4. I-Biocompatibility kunye nokhuseleko
Kwintsimi yamachiza, i-HPMC ithathwa ngokuba ne-biocompatibility efanelekileyo kunye ne-toxicity ephantsi, ngoko ke isetyenziswa ngokubanzi kuqulunqo lwamachiza. Ihlala isetyenziselwa ukulungiselela iziyobisi ezikhutshwa ngokuzinzileyo kuba zinokukhulula ngokuzinzileyo iziyobisi emzimbeni kwaye zinciphise iziphumo ebezingalindelekanga.
5. Uzinzo lweColloidal
I-HPMC inokuphucula ukuzinza kweenkqubo ze-colloidal kwaye ithintele i-particle precipitation okanye i-stratification. Oku kubaluleke kakhulu kwiimveliso zokuthambisa kunye nokunakekelwa kwesikhumba kuba iqinisekisa ukuba imveliso ihlala ifana kwaye izinzile ngexesha lokugcinwa kwexesha elide.
6. Ukukhululwa okulawulwayo
Iimpawu ze-HPMC ziyenza ibe ntle ekulawuleni ukukhutshwa kwechiza. Iyakwazi ukunyibilika emanzini ukwenza i-colloidal substance, evumela ukuba ichiza likhululwe kwizinga elilawulwayo. Le propati yokukhululwa elawulwayo ibaluleke kakhulu ekuphuculeni ukusebenza kweziyobisi kunye nokunciphisa ukuphindaphinda kwe-dosing.
7. Ukukhuselwa kwendalo kunye nokuhlaziywa
I-HPMC ithathwe kwi-cellulose yendalo, ngoko ineenzuzo ezithile zokusingqongileyo. Inkqubo yemveliso ihambelana nokusingqongileyo kwaye imveliso yokugqibela inokubola, ehlangabezana neemfuno zoshishino lwangoku ukwenzela uphuhliso oluzinzileyo.
I-Hydroxypropyl methylcellulose isetyenziswe ngokubanzi kumashishini amaninzi ngenxa yokuqina kwayo okugqwesileyo, i-gelling, ukubunjwa kwefilimu, ukuzinza kunye nokuhambelana kwezinto eziphilayo. Ukusuka ekutyeni ukuya kumayeza, ukusuka kulwakhiwo ukuya kwizinto zokuthambisa, i-HPMC iye yaba sisithako esiyimfuneko kwiimveliso ezininzi kunye neenkqubo ngenxa yokuguquguquka kwayo kunye nokuguquguquka.
