Le mveliso yi-2-ihydroxypropyl ether methyl cellulose, eyimveliso ye-semi-synthetic. Inokuveliswa ngeendlela ezimbini: (1) Emva kokunyanga iilitha zomqhaphu okanye iifiber zeplanga zomthi nge-caustic soda, zixutywe nekloromethane kunye ne-epoxy Propane isabela, icocwe kwaye icolwe ukuze ifumane; (2) Sebenzisa ibakala elifanelekileyo le-methyl cellulose ukunyanga nge-sodium hydroxide, uphendule ngepropylene oxide phantsi kobushushu obuphezulu kunye noxinzelelo oluphezulu ukuya kumgangatho ofanelekileyo, kwaye ucokiseke. Ubunzima bemolekyuli busuka kwi-10,000 ukuya kwi-1,500,000.
★ Ingqikelelo yendalo enyulu, yomeleza ukwetyisa nokufunxa.
★ Umthamo wamanzi aphantsi, 5% -8%. Ukuxhathisa okuqinileyo kokufunxa ukufuma, imixholo ayilula ukuyidibanisa, kwaye iqokobhe le-capsule akulula ukulikhubaza, libe brittle, kwaye libe lukhuni.
★ Akukho mngcipheko we-cross-linking reaction, akukho ukusebenzisana, ukuzinza okuphezulu, ekubeni i-hydroxypropyl methylcellulose i-cellulose derivative, akukho mngcipheko we-cross-linking reaction of protein substances kwi-gelatin.
★ Iimfuno eziphantsi zeemeko zokugcina:
Iphantse ingabi brittle kwindawo ephantsi yomswakama, inozinzo oluhle kumaqondo aphezulu, kwaye i-capsule ayiguquki.
★ Imigangatho efanayo kunye nokuhambelana okulungileyo:
Esebenzayo kwimigangatho ye-pharmacopoeia kazwelonke, imilo, ubungakanani, ukubonakala kunye nendlela yokuzalisa ilingana ne-gelatin capsules engenanto, kwaye akukho mfuneko yokutshintsha izixhobo kunye neengxenye.
★ Umthombo ongeyiwo wezilwanyana, akukho mngcipheko unokubakho wehomoni yokukhula okanye amachiza ashiywe kumzimba wesilwanyana.
IHydroxypropyl methylcelluloseii-capsules ezingenanto zahlukile kwii-capsules ze-gelatin zendabuko. Ziyihydroxypropyl methylcellulose (HPMC) eyenziwe ngomthi womthi. Ukongeza kwiinzuzo zengcamango yendalo ecocekileyo, i-hydroxypropyl methylcellulose capsules engenanto nayo Inokuphucula ukufunxa kunye nokugaya iprotheni, amafutha kunye ne-carbohydrates, kwaye ineenzuzo zobugcisa kunye neempawu ezingenayo i-gelatin yendabuko. Ngokukhuthazwa okuqhubekayo kolwazi lwabantu lokuzikhathalela, ukuphuhliswa kwemifuno, ukupheliswa kwesifo senkomo yenkomo, isifo sonyawo kunye nomlomo kwimpilo yabantu, kunye neempembelelo zenkolo nezinye izinto, iimveliso ze-capsule zendalo ezicocekileyo zendalo kunye nezityalo. iya kuba ngumkhombandlela okhokelayo wophuhliso lweshishini le-capsule. .
