HPMC
HPMC Hydroxypropyl Methyl Cellulose
Isishwankathelo semveliso
I-HPMC yi-semi-synthetic nonionic cellulose exutywe ne-ether ehlala ibonakala njengomgubo omhlophe okanye omhlophe. Ilungiswa ngokuguqulwa kweekhemikhali zeselulosi yendalo.
Ukunyibilika kakuhle kwamanzi: Inokunyibilika ngokukhawuleza emanzini abandayo ukwenza isisombululo se-viscous esicacileyo.
iimpawu zemveliso
Ukuqina okugqwesileyo: Ukuphucula ngokubonakalayo i-viscosity kunye nokuhambelana kolwelo, ukuphucula ulwelo kunye nokuzinza.
Ukubunjwa kwefilimu egqwesileyo: Xa yomisiwe, ifilimu enzima yenziwa, ekwazi ukumelana namanzi, iphefumula kwaye iguquguqukayo.
I-biocompatibility elungileyo: Ayinatyhefu, ayinancasa, ayicaphukisi, ifanelekile kwintsimi ye-biomedicine.
Ukonakala kokusingqongileyo: Kunokonakala ngokwendalo kokusingqongileyo, ngokuhambelana neemfuno zokhuselo lokusingqongileyo.
ukusetyenziswa kwemveliso
Ishishini lokwakha: Isetyenziswa njengearhente yokugcina amanzi kunye nearhente ebambezela udaka lwesamente ukuphucula ukwanda kunye nexesha lokusebenza; Njengento yokuncamathelisa, isetyenziselwa ukuncamathelisa izinto zokuhombisa ezifana neethayile kunye neebhastile.
Umzi-mveliso wokugquma: Njenge-thickener, dispersant kunye ne-stabilizer, ukuphucula ukusebenza kweengubo.
Intsimi yamachiza: Ingasetyenziselwa njengezinto zokugquma ifilimu, i-ejenti yokukhululwa eqhubekayo, i-capsule shell material, uncedo lokumiswa, njl.
Ishishini lokutya: Ukusebenza njenge-thickener, emulsifier, stabilizer kunye nezinye iindima.
Inkqubo yokuvelisa
Ngokuqhelekileyo umqhaphu, umthi njengezinto eziluhlaza, ngokusebenzisa i-alkalization, ipropylene oxide kunye nenkqubo ye-chloromethane etherification yokulungiselela.
Amathemba emarike
Ngophuhliso loqoqosho lwehlabathi kunye nokwazisa ngokusingqongileyo, imfuno yayo yentengiso iyaqhubeka nokukhula. Izicelo kwizakhiwo eziluhlaza, iingubo zokukhusela okusingqongileyo, i-biomedicine kunye nezinye iindawo ziyaqhubeka nokwanda, kwaye isikali semarike kulindeleke ukuba sandise ngakumbi. Kodwa kwangaxeshanye, eli shishini likwajongene nemingeni kwi-teknoloji entsha, ukhuphiswano lweemarike kunye neemfuno zokukhuselwa kwendalo.
sebenzisa izilumkiso
Kwinkqubo yokusetyenziswa, kuyimfuneko ukubeka ingqalelo kwindlela yokutshatyalaliswa, kwaye ukhethe indlela efanelekileyo yokuchithwa ngokwemizekelo eyahlukeneyo. Ngelo xesha, qaphela iimeko zokugcina, kufuneka zibekwe kwindawo epholileyo eyomileyo, ecocekileyo ukuze kuqinisekiswe umgangatho wemveliso kunye nokusebenza.
