Olu phawu ludlala indima ebalulekileyo ekumiseleni ukusebenza kwayo kwizicelo ezahlukeneyo, ukusuka kwimixube yamachiza ukuya kwi-samente kunye ne-adhesives tile.
Isishwankathelo se-HPMC
I-HPMC yi-ether ye-cellulose ye-nonionic ephuma kwi-cellulose yendalo ngokuzisa i-hydroxypropyl kunye namaqela e-methyl. Olu tshintsho luphumela kwipolymer enyibilikayo emanzini kwaye ibonise ukuziphatha kwe-thermogelling. Xa inyibilika, i-HPMC yenza isisombululo se-viscous, esicacileyo, esinika ukutyeba, ukwenza ifilimu, kunye neempawu zokuzinzisa.
Enye yeempawu eziphambili ze-HPMC kukukwazi ukusasaza emanzini abandayo ngaphandle kokwenza amaqhuma okanye i-aggregates. Le propati yenza lula ukuphathwa kwayo kunye nokusetyenziswa kwayo, iyenze ibe yinto efanelekileyo yokudibanisa kumashishini efuna umxube ochanekileyo kunye osebenzayo wesithako.
IiNdlela zokuNyekwa kwaManzi abandayo
I-dispersibility yamanzi abandayo ye-HPMC ilawulwa ikakhulu ziipropati zayo zomphezulu kunye ne-hydration kinetics. Iindlela eziphambili ziquka:
Ukuguqulwa komphezulu: Amasuntswana e-HPMC ahlala ephathwa ngee-arhente ezisebenza kumphezulu okanye i-hydrophilic coatings ukukhulisa ukusasazeka kwazo. Olu nyango lunciphisa ukudibanisa kwe-interparticle, ukuvumela ukuba amaqhekeza ahlukane ngokulula ngakumbi emanzini.
I-Hydration Kinetics: Xa ifakwe emanzini abandayo, amaqela e-hydrophilic kwi-HPMC atsala iimolekyuli zamanzi. I-hydration elawulwayo iqinisekisa ukusabalalisa ngokuthe ngcembe, ukuthintela ukubunjwa kwe-clumps okanye i-gel mass.
Uvakalelo lobushushu: I-HPMC ibonisa iprofayili eyodwa yokunyibilika. Inyibilika ngokulula emanzini abandayo kodwa yenza ijeli njengoko ubushushu bunyuka. Oku kuziphatha okuxhomekeke kwiqondo lokushisa kunceda ekusasazeni ngokulinganayo amasuntswana ngexesha lokusasazwa kokuqala.
Izinto Eziphembelela Ukusasazeka Kwamanzi Abandayo
Izinto ezininzi zinefuthe kwi-dispersibility yamanzi abandayo ye-HPMC, kubandakanywa nesakhiwo semolekyuli, ubungakanani bamasuntswana, kunye neemeko zokusingqongileyo:
