Ipolima yeHPMC

I-HPMC (i-Hydroxypropyl Methylcellulose) i-non-ionic, i-polymer enyibilikayo emanzini ephuma kwi-cellulose. Isetyenziswa ngokubanzi kwizicelo ezahlukeneyo, kubandakanya amayeza, ukutya, izinto zokuthambisa, kunye namanye amashishini. I-HPMC yipolymer eguquguqukayo enokusetyenziswa ukuguqula izinto eziphathekayo zeenkqubo ezinamanzi, ezifana ne-viscosity, i-tension surface, kunye nokunamathela.

I-HPMC yipolysaccharide eyenziwe ngeeyunithi eziphinda-phindayo zeemolekyuli zeglucose, ezidityaniswe kunye ngamaqela e-ether kunye ne-methyl. Amaqela e-ether anika i-HPMC ukunyibilika kwayo kwamanzi, ngelixa amaqela e-methyl anika i-polymer kunye ne-non-ionic character. Oku kwenza i-HPMC ibe lukhetho olufanelekileyo kwizicelo ezahlukeneyo, njengoko inokuthi isasazwe ngokulula emanzini kunye nezinye izinyibilikisi zepolar.

HPMC isetyenziswa kumashishini ahlukeneyo, kuquka amayeza, ukutya, izinto zokuthambisa, kunye namanye amashishini. Kumashishini amayeza, i-HPMC isetyenziswa njenge-binder, i-disintegrant, kunye ne-agent-forming agent. Ikwasetyenziswa njenge-excipient kwiipilisi kunye ne-capsules, njengoko inceda ukuphucula ukuhamba kunye nokunyanzeliswa kwe powders. Kwishishini lokutya, i-HPMC isetyenziswa njenge-thickener, stabilizer, kunye ne-emulsifier. Ikwasetyenziswa kwishishini lezithambiso njengearhente yokwenza ifilim kunye ne-emulsifier.

HPMC i polima ekhuselekileyo nesebenzayo ukuba non-ityhefu kwaye non-ukundicaphukisa. Iyakwazi ukubola kwaye ihambelana nokusingqongileyo. I-HPMC ifumaneka kwiindidi zamabanga kunye neefom, ezifana nomgubo, iigranules, kunye neeflakes. Ikwafumaneka kubunzima beemolekyuli ezahlukeneyo, ezinokuthi zilungelelaniswe ukuhlangabezana neemfuno ezithile.

HPMC lukhetho olufanelekileyo kuluhlu olubanzi lwezicelo ngenxa yokuguquguquka kwayo, ukhuseleko, kunye nokusebenza. I-polymer eneendleko kwaye inokwethenjelwa engasetyenziselwa ukuguqula iimpawu ezibonakalayo zeenkqubo zamanzi. I-HPMC sisithako esibalulekileyo kwiimveliso ezininzi, kwaye ukusetyenziswa kwayo kunokwenzeka ukuba kuqhubeke ukukhula kwixesha elizayo.
