IHydroxypropyl methylcellulose (HPMC) yipolymer eguquguqukayo esetyenziswa kumashishini ahlukeneyo, kubandakanywa amayeza, ulwakhiwo, ukutya, kunye nezinto zokuthambisa.Enye ipropati ephambili echaphazela kakhulu ukufaneleka kwayo yi-viscosity.I-Viscosity ibhekisela ekuchaseni ulwelo ukuba luhambe kwaye ludlala indima ebalulekileyo ekumiseleni ukusebenza kunye nokusebenza kwe-HPMC kwizicelo ezahlukeneyo.
1. Qonda i-HPMC:
IHydroxypropylmethylcellulose (HPMC) yi-semi-synthetic water-soluble polymer ephuma kwi-cellulose.
Ngenxa yeempawu zayo ezizodwa, isetyenziswa ngokuqhelekileyo njenge-thickener, stabilizer, ifilimu yangaphambili kunye ne-adhesive.
I-HPMC ifumaneka kumabakala ahlukeneyo, ngalinye linamanqanaba ahlukeneyo e-viscosity, echaphazela ukusebenza kwayo kwizicelo ezahlukeneyo.
2.Usetyenziso lwamayeza:
Kwicandelo lamachiza, i-HPMC isetyenziswa ngokubanzi kwiipilisi zeepilisi, iifomyula ezilawulwayo zokukhululwa kunye nokumiswa.
I-Viscosity idlala indima ebalulekileyo ekulawuleni ubukhulu kunye nokufana kwe-tablet coating, ukuqinisekisa ukukhutshwa okufanelekileyo kwechiza kunye ne-bioavailability.
I-viscosity ye-HPMC nayo ichaphazela iimpawu zokuhamba zokunqunyanyiswa kunye nokuzinza kokuqulunqwa, ngaloo ndlela kuchaphazela ukuhanjiswa kweziyobisi kunye nokuthotyelwa kwesigulane.
3.Ishishini lokwakha:
I-HPMC isetyenziswa kakhulu kushishino lolwakhiwo njenge-arhente yokujiya kwiidaka ezisekwe kwisamente, izinto zokuncamathelisa iithayile kunye neeplasta.
I-Viscosity ichaphazela ukusebenza kunye nokuxhathisa kwe-sag yokwenziwa kodaka, ukuqinisekisa ukubambelela ngokufanelekileyo kunye nokunciphisa inkunkuma yezinto eziphathekayo ngexesha lokwakha.
Ngokulungelelanisa i-viscosity yokuqulunqwa kwe-HPMC, abakhi banokufezekisa ukuhambelana okufunwayo kunye neempawu zokusebenza, ngaloo ndlela baphucula umgangatho opheleleyo weeprojekthi zabo zokwakha.
4. Ishishini lokutya neziselo:
Kushishino lokutya nesiselo, i-HPMC isetyenziswa njenge-thickener, emulsifier kunye ne-stabilizer kwiimveliso ezahlukeneyo ezibandakanya iisosi, isuphu kunye nezinye iindlela zobisi.
I-Viscosity ichaphazela ukuthungwa, i-mouthfeel kunye nokuzinza kokutya, ukuqinisekisa iimpawu ezifanelekileyo zokuziva kunye nobomi beshelufu.
Abavelisi bokutya bakhetha ngononophelo amabanga e-HPMC anamanqanaba athile e-viscosity ukufikelela kwimveliso enqwenelekayo kunye neemfuno zokusetyenzwa.
5. Izinto zokuthambisa kunye neemveliso zokhathalelo lomntu:
I-HPMC isetyenziswa njengesixhobo esityebisayo kunye nokwenza ifilim kwizithambiso kunye neemveliso zokhathalelo lomntu ezifana neekhrimu, izinto zokuthambisa kunye neeshampu.
I-Viscosity idlala indima ebalulekileyo ekulawuleni ukuhambelana kwemveliso, ukusasazeka kunye nokuzinza, ukuphucula amava omsebenzisi kunye nokusebenza kwemveliso.
Abenzi bezinto zokuthambisa baxhomekeke kwi-HPMC ngeeprofayili ze-viscosity ezilungiselelwe ukufezekisa i-rheology efunwayo kunye neempawu zoluvo ekuqulunqweni kwazo.
6. Ukubaluleka kolawulo lwe-viscosity:
Ulawulo oluchanekileyo lwe-viscosity lubalulekile ukuhlangabezana neemfuno ezithile zezicelo ezahlukeneyo.
Abavelisi banikezela ngamabakala ahlukeneyo e-HPMC anamanqanaba ahluka-hlukeneyo e-viscosity, evumela abaqulunqi ukuba bakhethe ibakala elifanelene kakhulu nesicelo sabo.
Umlinganiselo ochanekileyo we-viscosity kunye ne-rheological characterization yenza ukuba abaqulunqi basebenzise iifomyula kunye nokuqinisekisa ukusebenza kwemveliso kunye nomgangatho.
7. Izinto ezichaphazela i-viscosity:
Izinto ezininzi, kubandakanywa ugxininiso lwepolymer, ubunzima bemolekyuli, iqondo lokutshintshwa, kunye nobushushu, kunokuchaphazela i-viscosity yezisombululo ze-HPMC.
Ukuqonda ubudlelwane phakathi kwezi zinto kunye ne-viscosity kubalulekile ekuqulunqeni iimveliso ze-HPMC ezineempawu zokusebenza ezinqwenelekayo.
I-Viscosity yiparameter ebalulekileyo enokuchaphazela kakhulu ukusebenza kunye nokusebenza kwe-HPMC kwizicelo ezahlukeneyo.
Kumashishini amayeza, ulwakhiwo, ukutya, izimonyo kunye nokunyamekela komntu, ukulawulwa ngokuchanekileyo kwe-viscosity kubalulekile ukuhlangabezana neemfuno ezithile zokuqulunqa kunye nokufezekisa iimpawu ezifunwayo zemveliso.Ngokuqonda ukubaluleka kwe-viscosity kunye neempembelelo zayo kwizicelo ze-HPMC, abavelisi kunye nabaqulunqi banokulungisa iifomyula ukuphucula ukusebenza kwemveliso, umgangatho kunye nokwaneliseka kwabathengi.I-Viscosity yinto ephambili ekunqumeni ukusebenza kunye nokusebenza kwe-HPMC kwiintlobo ezahlukeneyo zezicelo.Ulawulo lwayo ngononophelo kunye nokuqonda kubalulekile ukufezekisa iimpawu ezinqwenelekayo zemveliso kunye nokuqinisekisa impumelelo kuwo wonke amashishini.
