Zithini iipropathi ze-HOOOOOLOCMC?

Zithini iipropathi ze-shilogical yeI-HPMC?

I-HydroxyPOpyl Methylcelcelsele (i-HPMC) yi-polymer eguquguqukayo efumana ukusetyenziswa okukhulu kumashishini ahlukeneyo, kubandakanya amayeza, ukwakhiwa, ukutya, kunye ne-cosmetics, ikakhulu ngenxa yezakhiwo zayo ezahlukileyo. I-RHOOLOLOLO LUFUNDWA kukuhamba kunye nokusebenza kwezinto, kunye nokuqonda iipropathi ze-HPMC kubalulekile ukuze zisebenzele ukusebenza kwezicelo ezahlukeneyo.

I-viscosity: i-HPMC ibonakalisa i-pseudoplastic okanye indlela yokuziphatha ye-shear, intsingiselo yokufakwa kwayo kuncipha ngokukhula kwenqanaba le-Shear. Le ndawo ibalulekile kwizicelo ezinje ngemisebenzi yamayeza, apho ivumela ukumpompela ngokulula, ukusasazeka, kunye nesicelo. I-Viscosity inokulungelelaniswa ngokuguqula inqanaba lokufakwa endaweni (DS) kunye nobunzima bemoya ye-HPMC.

I-Thixotdropy: I-Thizotropy ibhekisa kwinguqulelo eguqukayo ye-gel-sol ye-gel-sol ye-gel-sol ye-gel-sol ye-SOL evaliweyo ngezinto ezithile phantsi koxinzelelo lweShear. I-HPMC i-HPMC yenziwe ukuphumla kunokuqhekeza phantsi koShear kwaye ufumane ulwakhiwo lwabo lwejele xa uxinzelelo lususwe. Le ndawo iluncedo kwizicelo ezinjengepeyinti, apho ithintela ukuqhubela phambili ngexesha lokufaka isicelo kodwa iqinisekisa ukuba isetyenziswe kakuhle.

I-hydmire: i-HPMC i-hygroscopic kwaye inokufunxa amanzi, ekhokelela ekudumbe kunye nokunyuka kwe-viscosity. Inqanaba lokuhamba-mbambano lixhomekeke kwizinto ezinje ngamaqondo obushushu, i-PH, kunye ne-Ionic yendawo ephakathi. Ukudlala i-hydration idlala indima ebalulekileyo ekulawuleni ukukhululwa kwamachiza ukusuka kwimizobo yamayeza kunye nokugcina umxholo wokufuma kwiimveliso zokutya.

Imvakalelo yobushushu:I-HPMCIzisombululo ezibonisa ubushushu obuxhomekeke kubushushu, kunye nokupheliswa kwe-viscofity njengamaqondo obushushu ayanda. Nangona kunjalo, le ndlela yokuziphatha inokwahluka ngokuxhomekeka kwizinto ezinje nge-polymer gxili kunye nesisombululo seP. Imvakalelo yobushushu ibalulekile kwizicelo ezinjengezinto zokwakha, apho ichaphazela ukusebenza nokubeka ixesha.

Imvakalelo ye-ityuwa: Izisombululo ze-HPMC zinokubonakalisa imvakalelo yokutsala, kunye nezinye iityuwa ezibangela ukuphuculwa kwe-viscofity. Le phenonon ichazwe kunxibelelwano phakathi kweemolekyuli ze-HPMC kunye nee-ions kwisisombululo. Imvakalelo yetyuwa ibalulekile kwiifom zamayeza kunye neemveliso zokutya apho umxholo wetyuwa kufuneka ulawulwe ngononophelo.

Ixabiso le-Shear Ukuxhomekeka: Iipropathi ze-ROOIL SORTMS zesisombululo ze-HPMC zixhomekeke kakhulu kwinqanaba leShear lisetyenzisiwe. Ngamaxabiso asezantsi asezantsi, i-viscosity iphezulu ngenxa yokunyuka kwe-moleculant, ngelixa amaxabiso aphezulu asechibini, i-viscosity ihla ngenxa yokuthoba i-shear. Ukuqonda inqanaba lesinga lokuxhomekeka kwenqanaba lokuxhomekeka kubalulekile ekuyileni iimeko zokulungisa kwizicelo ezahlukeneyo.

Ukumiswa kwe-suricle: i-HPMC inokuthatha amanyathelo njengearhente yokumisa amasuntswana kwifomuli yolwelo ngenxa yokuthambisa kunye nokuzinzisa iipropathi. Inceda ukuthintela amasuntswana aqinileyo, kuqinisekisa ukusasazwa okungafaniyo kunye nokungaguquguquki kwiimveliso ezinjengeepeyinti, imingxunya, kunye nokumiswa kwamayeza.

Ukuqulunqwa kwejeli:I-HPMCUnokwenza i-gels kwindawo ephezulu okanye phambi kweearhente ezinqamlezileyo ezifana neendawo ezidluleleyo. Ezi galls zibonakalisa iipropathi ze-viscoesti kwaye zisetyenziswa kwizicelo ezinje ngokuhanjiswa kwamachiza, apho kukhangelwa ukukhululwa kwezithako ezisebenzayo.

Ipropathi ye-RTMC, kubandakanya i-vixmosity, i-Thixotdropy, i-hydration, iqondo lobushushu kunye nokumiswa kwexabiso le-Shear, idlala indima ebalulekileyo ekuqinisekiseni ukusebenza kwawo kwizicelo ezahlukeneyo zemveliso. Ukuqonda nokulawula ezi ndawo kubalulekile ukuze kuqinisekiswe ukuqulunqwa kunye nokulungiswa kweemveliso ezisekwe kwi-HPMC.
