Umahluko kwiipropathi zomzimba kunye neekhemikhali phakathi kwe-HPMC kunye ne-HEMC

I-Hydroxypropyl Methylcelcelcelse Nangona izakhiwo zabo zekhemikhali ziyafana, kukho umahluko kwipropathi yabo ebangela ukuba balungele izicelo ezahlukeneyo.

1.Kwazisa uMgangatho:

Zombini i-HPMC kunye ne-HMC zithathwe kwi-sellyulose, i-polymer yendalo. Umahluko ophambili ulele kwizinto eziqhotyoshelwe kwi-selsulose plarbone. Kwi-HPMC, impahla yokuthabatha iquka i-methyl kunye ne-hydroxylpropyl, ngelixa i-HMC, i-HMC, indawo iquka i-methyl kunye ne-hydroxyteyteyl. Olu mpahla lunokuchaphazela iipropathi zonke ze-seluplose

I-2. Ukungasebenzi:

Umahluko obalulekileyo phakathi kwe-HPMC kunye ne-HMC yindlela yabo yokuziphatha. I-HPMC ibonisa ukugcwaliswa okungcono kumanzi abandayo xa kuthelekiswa ne-HMC. Le mpahla ibalulekile kwizicelo ezifuna ukuchithwa okukhawulezayo okanye ukusasazeka kweepolimers, ezinje ngamashishini amayeza nolwakhiwo.

3. Ukugcinwa kwamanzi:

I-HPMC ngokubanzi inomthamo ongcono wamanzi kune-HEMC. Le ndawo ibaluleke kakhulu kwizicelo ezinjengeenkqubo ezisekwe kwimozulu, apho ukugcinwa kwamanzi kunceda ukulawula inkqubo ye-hydration kunye nokuphucula ukusebenza.

4. Ubushushu be-gene:

Iqondo lobushushu leqela liqondo lobushushu apho isisombululo okanye ukusasazeka sitshintsha kwijeli. I-HMC ngokubanzi icacisa iigesi kumaqondo obushushu asezantsi kune-HPMC. Le ndawo inokuba yingenelo kwizicelo ezinje ngeemveliso zokutya, apho amaqondo obushushu asezantsi anokufuneka kwiimeko ezithile zokwenza.

5.UPRORTITO LEMPILO:

Zombini i-HPMC kunye ne-HMC ifaka igalelo kwindlela yokuziphatha kakuhle yezisombululo okanye ukusasazeka. Nangona kunjalo, iziphumo zabo kuhlobo lwe-viscosity kunye nokuziphatha kwe-shear ukucinga kungahluka. I-HMC ngokubanzi ibonelela ngokuvisisa okuphezulu kwiindawo eziphantsi, zenza ilungele ukusetyenziswa kwezinye izinto ezifuna izisombululo ezihlanganisiweyo.

6. Ukuqulunqwa kwefilimu:

I-HPMC kunye ne-HMC inokwenza iifilimu ezincinci xa zisetyenziswa kwimiphezulu. Kuxhomekeka kwi-selsulose ether esetyenziswayo, iifilimu ezibonisa iipropathi ezahlukeneyo. Iifilimu ze-HPMC zihlala ziguquguquka ngakumbi, ngelixa iifilimu ze-hemc zibrittle. Le propati ichaphazela ukusetyenziswa kwabo kwi-cayintings, amachaphaza kunye nezinye iinkqubo zokwenza ifilimu.

I-7. Ukuhambelana nezinye iingcongolo:

Ukukhetha phakathi kwe-HPMC kunye ne-HMC kuya kuxhomekeka ekulungelelanisweni kwabo nezinye izinto ezihlanganisiweyo. Umzekelo, i-HPMC ihlala ikhethwa kwiifomu zamayeza ngenxa yokuhambelana kwezithako ezahlukeneyo, ngelixa iHMC inokukhethwa kwizicelo ezithile ngokusekwe kwiimpawu zawo.

8. Uzinzo lobushushu:

Zombini isellulose ethen ibonakalisa uzinzo oluhle, kodwa amaqondo obushushu apho ade ahlukane khona. I-HPMC idla ngokufumana uzinzo oluphezulu lwe-thermal ophezulu xa kuthelekiswa ne-HMC. Eli nqaku libalulekile kwizicelo apho kuvezwa khona amaqondo obushushu aphezulu.

Nangona i-HPMC kunye ne-HMC yabelana nge-Ilebose yeSelsulose, indawo yabo yemichiza emichithe isiphumo kwiipropathi ezahlukeneyo zomzimba kunye nekhemikhali. Ukuqonda lo mahluko kubalulekile ekukhetheni i-ether efanelekileyo ye-ether yesicelo esinikiweyo, ukuqinisekisa ukusebenza kakuhle kunye nokusebenza. Ukukhetha phakathi kwe-HPMC kunye ne-HMC kuxhomekeke kwiimfuno ezithile zesicelo, ukusukela kwi-chirmaceuticals kunye nezixhobo zokwakha nokutya kunye neengubo.
