I-HPMC (i-hydroxypropyl methylcellulose)Iikhaphu zezinye zezinto ezisetyenziswa kakhulu kwiikhaphu kumayeza anamhlanje nakwizongezo zokutya. Zisetyenziswa kakhulu kwishishini lamayeza nakwishishini lemveliso yokhathalelo lwempilo, kwaye ziyathandwa ngabantu abangatyi nyama kunye nezigulane ezine-allergies ngenxa yezithako zayo ezivela kwizityalo. Iikhaphu zeHPMC ziyanyibilika kancinci kancinci kwindlela yesisu emva kokuzitya, ngaloo ndlela zikhupha izithako ezisebenzayo kuzo.
1. Isishwankathelo sexesha lokuchithwa kwekhaphu ye-HPMC
Ixesha lokunyibilika kweekhaphu zeHPMC lidla ngokuba phakathi kwemizuzu eli-10 ukuya kwengama-30, nto leyo exhomekeke kakhulu kubukhulu bodonga lwekhaphu, inkqubo yokulungiselela, uhlobo lomxholo wekhaphu, kunye nezinto ezingqongileyo. Xa kuthelekiswa neekhaphu ze-gelatin zemveli, izinga lokunyibilika kweekhaphu zeHPMC lihamba kancinci, kodwa lisekwinqanaba elamkelekileyo lendlela yokugaya ukutya yomntu. Ngokubanzi, amayeza okanye izondlo zinokukhutshwa ngokukhawuleza kwaye zifunxwe emva kokuba ikhaphu inyibilikisiwe, ukuqinisekisa ukuba izithako ezisebenzayo ziyafumaneka.
2. Izinto ezichaphazela izinga lokunyibilika kweekhaphu zeHPMC
Ixabiso le-pH kunye nobushushu
Iikhaphu zeHPMC zinyibilika ngcono kwiindawo ezineasidi nezingathathi cala, ngoko ke zinokunyibilika ngokukhawuleza esiswini. Ixabiso le-pH yesisu lidla ngokuba phakathi kwe-1.5 ne-3.5, kwaye le ndawo ineasidi inceda iikhaphu zeHPMC ukuba ziqhekeke. Kwangaxeshanye, ubushushu obuqhelekileyo bomzimba womntu (37°C) bunokukhuthaza ukunyibilika ngokukhawuleza kweekhaphu. Ke ngoko, kwindawo eneasidi yesisu, iikhaphu zeHPMC ngokubanzi zinokunyibilika ngokukhawuleza kwaye zikhuphe umxholo wazo.
Ubukhulu kunye noxinano lodonga lwekhaphu yeHPMC
Ubukhulu bodonga lwekhaphu buchaphazela ngokuthe ngqo ixesha lokunyibilika. Iindonga zekhaphu ezityebileyo zithatha ixesha elingakumbi ukunyibilika ngokupheleleyo, ngelixa iindonga zekhaphu ezibhityileyo zinyibilika ngokukhawuleza. Ukongeza, ubuninzi bekhaphu yeHPMC buya kuchaphazela nesantya sayo sokunyibilika. Iikhaphu ezixineneyo ziya kuthatha ixesha elide ukuqhekeka esiswini.
Uhlobo kunye nohlobo lomxholo
Izithako ezifakwe ngaphakathi kwikhaphu nazo zinefuthe elithile kwizinga lokunyibilika. Umzekelo, ukuba umxholo une-asidi okanye uyanyibilika, ikhaphu iya kunyibilika ngokukhawuleza esiswini; ngelixa kwezinye izithako ezinamafutha, kungathatha ixesha elide ukunyibilika. Ukongeza, izinga lokunyibilika komxholo womgubo kunye nolwelo nalo lahlukile. Ukusasazwa komxholo wolwelo kuyafana ngakumbi, nto leyo enceda ekuqhekekeni ngokukhawuleza kweekhaphu zeHPMC.
Ubungakanani bekhaphu
I-HPMCIikhaphu ezineenkcazo ezahlukeneyo (ezifana neNombolo 000, Nombolo 00, Nombolo 0, njl.njl.) zinezinga ezahlukeneyo zokunyibilika. Ngokubanzi, iikhaphu ezincinci zithatha ixesha elifutshane ukunyibilika, ngelixa iikhaphu ezinkulu zineendonga ezixineneyo kunye nomxholo omninzi, ngoko ke zithatha ixesha elide ukunyibilika.
Inkqubo yokulungiselela
Ngexesha lenkqubo yokuvelisa ii-capsules ze-HPMC, ukuba kusetyenziswa ii-plasticizers okanye kongezwa ezinye izithako, iimpawu zokunyibilika kwee-capsules zinokutshintsha. Umzekelo, abanye abavelisi bongeza i-glycerin yemifuno okanye ezinye izinto kwi-HPMC ukuze kuphuculwe ukuthamba kwee-capsules, nto leyo enokuchaphazela izinga lokuqhekeka kwee-capsules ukuya kwinqanaba elithile.
Umswakama kunye neemeko zokugcina
Iikhaphu zeHPMC zinobuthathaka kumswakama kunye neemeko zokugcina. Ukuba zigcinwe kwindawo eyomileyo okanye enobushushu obuphezulu, iikhaphu zinokuba buthathaka, nto leyo etshintsha izinga lokunyibilika esiswini somntu. Ke ngoko, iikhaphu zeHPMC zihlala zifuna ukugcinwa kwindawo enobushushu obuphantsi kunye nendawo eyomileyo ukuqinisekisa uzinzo lwezinga lokunyibilika kwazo kunye nomgangatho wazo.
3. Inkqubo yokunyibilikisa iikhaphu zeHPMC
Inkqubo yokunyibilika kweekhaphu zeHPMC yahlulwe ngokubanzi ibe ngamanqanaba amathathu:
Inqanaba lokuqala lokufunxa amanzi: Emva kokufunxa, ii-capsules ze-HPMC ziqala ukufunxa amanzi kwijusi yesisu. Umphezulu we-capsule uba manzi kwaye kancinci kancinci uqala ukuthamba. Ekubeni ulwakhiwo lwee-capsules ze-HPMC lunomlinganiselo othile wokufunxa amanzi, eli nqanaba lidla ngokuba ngokukhawuleza.
Inqanaba lokudumba nokuqhekeka: Emva kokufunxa amanzi, udonga lwekhaphu luyavuvuka kancinci kancinci ukuze lwenze umaleko we-gelatinous. Olu maleko lubangela ukuba ikhaphu iqhekeke ngakumbi, kwaye umxholo emva koko uyabonakala kwaye ukhululwe. Eli nqanaba limisela izinga lokunyibilika kwekhaphu kwaye likwangundoqo ekukhutshweni kwamayeza okanye izondlo.
Inqanaba lokunyibilika ngokupheleleyo: Njengoko ukuqhekeka kuqhubeka, ikhaphu iyanyibilika ngokupheleleyo, umxholo ukhululwe ngokupheleleyo, kwaye unokufunxwa ngumzimba womntu. Ngokwesiqhelo kwimizuzu eli-10 ukuya kwengama-30, iikhaphu zeHPMC zinokugqiba inkqubo ukusuka ekuqhekekeni ukuya ekunyibilikeni ngokupheleleyo.
Inkqubo yokulungiselela
Ngexesha lenkqubo yokuvelisa ii-capsules ze-HPMC, ukuba kusetyenziswa ii-plasticizers okanye kongezwa ezinye izithako, iimpawu zokunyibilika kwee-capsules zinokutshintsha. Umzekelo, abanye abavelisi bongeza i-glycerin yemifuno okanye ezinye izinto kwi-HPMC ukuze kuphuculwe ukuthamba kwee-capsules, nto leyo enokuchaphazela izinga lokuqhekeka kwee-capsules ukuya kwinqanaba elithile.
Umswakama kunye neemeko zokugcina
Iikhaphu zeHPMC zinobuthathaka kumswakama kunye neemeko zokugcina. Ukuba zigcinwe kwindawo eyomileyo okanye enobushushu obuphezulu, iikhaphu zinokuba buthathaka, nto leyo etshintsha izinga lokunyibilika esiswini somntu. Ke ngoko, iikhaphu zeHPMC zihlala zifuna ukugcinwa kwindawo enobushushu obuphantsi kunye nendawo eyomileyo ukuqinisekisa uzinzo lwezinga lokunyibilika kwazo kunye nomgangatho wazo.
3. Inkqubo yokunyibilikisa iikhaphu zeHPMC
Inkqubo yokunyibilika kweekhaphu zeHPMC yahlulwe ngokubanzi ibe ngamanqanaba amathathu:
Inqanaba lokuqala lokufunxa amanzi: Emva kokufunxa, ii-capsules ze-HPMC ziqala ukufunxa amanzi kwijusi yesisu. Umphezulu we-capsule uba manzi kwaye kancinci kancinci uqala ukuthamba. Ekubeni ulwakhiwo lwee-capsules ze-HPMC lunomlinganiselo othile wokufunxa amanzi, eli nqanaba lidla ngokuba ngokukhawuleza.
Inqanaba lokudumba nokuqhekeka: Emva kokufunxa amanzi, udonga lwekhaphu luyavuvuka kancinci kancinci ukuze lwenze umaleko we-gelatinous. Olu maleko lubangela ukuba ikhaphu iqhekeke ngakumbi, kwaye umxholo emva koko uyabonakala kwaye ukhululwe. Eli nqanaba limisela izinga lokunyibilika kwekhaphu kwaye likwangundoqo ekukhutshweni kwamayeza okanye izondlo.
Inqanaba lokunyibilika ngokupheleleyo: Njengoko ukuqhekeka kuqhubeka, ikhaphu iyanyibilika ngokupheleleyo, umxholo ukhululwe ngokupheleleyo, kwaye unokufunxwa ngumzimba womntu. Ngokwesiqhelo kwimizuzu eli-10 ukuya kwengama-30, iikhaphu zeHPMC zinokugqiba inkqubo ukusuka ekuqhekekeni ukuya ekunyibilikeni ngokupheleleyo.
