Ngaba i-hydroxypropyl methylcellulose kunye ne-hypromellose ziyafana?

I-Hydroxypropyl methylcellulose (HPMC) kunye ne-hypromellose ngokwenene ziyikhompawundi enye, kwaye amagama ahlala esetyenziswa ngokutshintshanayo.Lawa ngamagama anzima kwiintlobo eziqhelekileyo zeepolymers ezisekelwe kwi-cellulose ezinoluhlu olubanzi lwezicelo kumashishini ahlukeneyo kuquka amayeza, ukutya kunye nezithambiso.

1. Ubume beMichiza kunye nokwakheka:

I-Hydroxypropylmethylcellulose (HPMC) yinguqulelo eyenziweyo ye-cellulose, i-polymer yendalo efumaneka kwiindonga zeeseli zezityalo.Ubume bemichiza ye-HPMC ifunyenwe ngokuzisa i-hydroxypropyl kunye namaqela e-methyl ngokwesiseko seselulosi.Iqela le-hydroxypropyl lenza i-cellulose i-soluble ngakumbi emanzini, kwaye iqela le-methyl liphucula ukuzinza kwalo kwaye linciphisa ukusebenza kwalo kwakhona.

2. Inkqubo yokwenziwa kwemveliso:

Ukuveliswa kwe-hydroxypropyl methylcellulose kubandakanya ukunyanga i-cellulose nge-propylene oxide ukwazisa amaqela e-hydroxypropyl kunye ne-methyl chloride ukongeza amaqela e-methyl.I-degree of substitution (DS) ye-hydroxypropyl kunye ne-methyl inokulungelelaniswa ngexesha lenkqubo yokuvelisa, okukhokelela kumabakala ahlukeneyo e-HPMC eneempawu ezahlukeneyo.

3. Iimpawu ezibonakalayo:

I-HPMC imhlophe ukuya kumgubo omhlophe kancinci, ayinavumba kwaye ayinancasa.Iimpawu zayo ezibonakalayo, ezifana ne-viscosity kunye ne-solubility, zixhomekeke kwinqanaba lokutshintshwa kunye nobunzima be-molecular of polymer.Kwiimeko eziqhelekileyo, i-soluble ngokulula emanzini, yenza isisombululo esicacileyo nesingenambala.

4. Iinjongo zonyango:

Esinye sezicelo eziphambili ze-HPMC kushishino lwamayeza.Isetyenziswa ngokubanzi njenge-excipient yamachiza kwaye idlala iindima ezahlukeneyo kumalungiselelo amayeza.I-HPMC iqhele ukufunyanwa kwiifomu zedosi yodosi yomlomo eqinileyo njengeepilisi, iipilisi, iipilisi.Isebenza njenge-binder, i-disintegrant, kunye ne-arhente yokukhululwa elawulwayo, igalelo kuzinzo jikelele kunye ne-bioavailability yechiza.

5. Indima kumalungiselelo okukhululwa alawulwayo:

Ukukwazi kwe-HPMC ukwenza iijeli kwizisombululo ezinamanzi kuyenza ixabiseke ekuqulunqweni kweziyobisi ezilawulwayo.Ngokutshintsha i-viscosity kunye ne-gel-forming properties, izazinzulu zamachiza zinokulawula izinga lokukhululwa kwezithako ezisebenzayo, ngaloo ndlela zifezekise isenzo seziyobisi eziqhubekayo kunye nexesha elide.

6. Ukusetyenziswa kushishino lokutya:

Kwishishini lokutya, i-HPMC isetyenziswa njenge-thickener, stabilizer kunye ne-emulsifier.Iphucula ukuthungwa kokutya okwahlukeneyo, kubandakanywa iisosi, iisuphu kunye neemveliso zobisi.Ukongeza, i-HPMC isetyenziselwa ukubhaka okungekho gluten-free ukunyusa isakhiwo kunye neempawu zokufuma kwiimveliso ezingenagluten.

7. Izinto zokwakha kunye nezinto zokwakha:

I-HPMC isetyenziswa kushishino lolwakhiwo kwiimveliso ezifana nokuncamathelisa iithayile, iiplasta ezisekwe kwisamente kunye nezinto ezisekwe kwigypsum.Iphucula ukusetyenzwa, ukugcinwa kwamanzi kunye neempawu zokubambelela kwezi mveliso.

8. Izinto zokuthambisa kunye neemveliso zokhathalelo lomntu:

I-Hypromellose ikwasisithako esiqhelekileyo kwizithambiso kunye neemveliso zokhathalelo lomntu.Isetyenziswa kwi-creams, lotions kunye ne-shampoos ngenxa yokuqina kwayo kunye nokuzinza kwayo.Ukongezelela, inceda ukuphucula ukuthungwa ngokubanzi kunye nokuvakalelwa kwemveliso.

9. Ukugqunywa kwefilimu kumayeza:

I-HPMC isetyenziswa kakhulu kwishishini lamachiza ukugquma ifilim yamacwecwe.Iipilisi ezigqunywe ngefilimu zibonelela ngenkangeleko ephuculweyo, incasa yokufihla incasa kunye nokukhuselwa kwizinto ezisingqongileyo.Iifilimu ze-HPMC zibonelela ngengubo egudileyo nefanayo, iphucula umgangatho uwonke wemveliso yeziyobisi.

13. Isiphelo:

IHydroxypropyl methylcellulose (HPMC) kunye ne-hypromellose zibhekisa kwipolymer esekwe kwi-cellulose eneentlobo ngeentlobo zezicelo kumayeza, ukutya, izimonyo kunye nokwakhiwa.Iimpawu zayo ezizodwa, ezifana nokunyibilika, ukuzinza kunye nokubola kwe-biodegradability, igalelo ekusetyenzisweni kwayo ngokubanzi.Ukuguquguquka kweHPMC kumashishini ahlukeneyo kuqaqambisa ukubaluleka kwayo njengesixhobo esinemisebenzi emininzi, kwaye iyaqhubekauphendlo nophuhliso lunokuveza usetyenziso olongezelelweyo kwixesha elizayo.

Olu qwalaselo lubanzi lujolise ekuboneleleni ngeenkcukacha ezicacileyo ze-hydroxypropyl methylcellulose kunye ne-hypromellose, ukucacisa ukubaluleka kwazo kwiinkalo ezahlukeneyo, kunye nokucacisa indima yabo ekubunjweni kweemveliso ezininzi kunye nokuqulunqwa.
