Ukufakwa kodaka HPMC

IHydroxypropylmethylcellulose (HPMC) sisongezo sodaka esisetyenziswa ngokuqhelekileyo kushishino lokwakha. Yi-ether ye-cellulose eguqulwayo ephuma kwiipolima zendalo, ngokukodwa i-cellulose. Ifumaneka kwifom yomgubo, i-HPMC ihlakazwa ngokulula emanzini ukwenza isisombululo se-colloidal.

Xa yongezwa kwimixube esekwe kwisamente, i-HPMC ineempawu ezininzi eziluncedo:

Ukugcinwa kwamanzi: I-HPMC isebenza njenge-arhente yokugcina amanzi, ivumela udaka ukuba lugcine ukusebenza kwalo ixesha elide. Oku kuluncedo ngakumbi kwiindawo ezishushu nezomileyo apho ukufuma okukhawulezileyo kokufuma kunokubangela ukuba udaka lome ngaphambi kwexesha.

Ukuphuculwa kokuSebenza: Ngokwandisa ukuhambelana kunye neplastiki yodaka, i-HPMC iphucula ukusebenza kwayo, okwenza kube lula ukuxuba, ukusasazeka kunye nokusebenzisa. Oku kuphucula iimpawu zokuphatha jikelele zodaka.

I-Adhesion eyandisiweyo: I-HPMC iphucula ukunamathela phakathi kodaka kunye nee-substrates ezahlukeneyo ezifana nekhonkrithi, izitena kunye nethayile. Oku kukhuthaza ukudibanisa okungcono kwaye kunciphisa umngcipheko wokutshatyalaliswa okanye ukwahlukana.

I-Sag eNcitshisiweyo: I-HPMC inceda ukukhusela udaka ukuba ungagxumeki okanye uwohloke xa usetyenziswa kumphezulu othe nkqo, uqinisekisa ukhuselo olungcono kunye nokunciphisa imfuno yokusebenza kwakhona.

Ixesha elongeziweyo lokuVula: Ukongezwa kwe-HPMC kwandisa ixesha elivulekileyo lodaka, ngaloo ndlela kwandiswa ifestile yexesha apho udaka luhlala lusebenza kwaye lubambisene. Oku kuluncedo ngakumbi kwiiprojekthi ezinkulu okanye ezinzima ezifuna ixesha elingakumbi lokufaka isicelo.

Ukuphuculwa koKuhlala ixesha elide: I-HPMC yonyusa ukuqina okupheleleyo kodaka ngokunciphisa ukuncipha, ukuqhekeka kunye nokungena kwamanzi. Iphakamisa umanyano kunye nokuthembeka kodaka, okwenza imveliso yokugqibela yomelele kwaye yomelele ngakumbi.

Ubungakanani obuchanekileyo be-HPMC efunekayo kuqulunqo lodaka lunokwahluka ngokuxhomekeke kwizinto ezifana neempawu ezinqwenelekayo, iimeko zokusingqongileyo kunye nohlobo lodaka olusetyenzisiweyo. Kunconywa ukuba ulandele izikhokelo zomenzi kunye namaphepha edatha yezobugcisa kwi-dosage efanelekileyo kunye nemiyalelo yesicelo.

Ngokubanzi, i-HPMC yinto yokongeza esebenzayo ephucula ukusebenza kodaka kunye nemixube esekwe kwisamente, ukuphucula ukusebenza, ukunamathela kunye nokuqina.
