Ichi chigadzirwa 2-hydroxypropyl ether methyl cellulose, inova semi-synthetic chigadzirwa. Inogona kugadzirwa nenzira mbiri: (1) Mushure mekurapa mapeji ekotoni kana huni dzehuni dzehuni ne caustic soda, dzinosanganiswa nekloromethane uye epoxy Propane inopindirana, inonatswa uye yakapwanyika kuti iwane; (2) Shandisa giredhi rakakodzera remethyl cellulose kurapa nesodium hydroxide, ita nepropylene oxide pasi pekupisa kwakanyanya uye kudzvanywa kwepamusoro kusvika padanho rakakodzera, uye gadzirisa. Huremu hwemamorekuru hunobva pa10,000 kusvika ku1,500,000.
★ Yakachena yakasikwa pfungwa, kusimudzira kugaya uye kunyura.
★ Mvura yakaderera, 5% -8%. Yakasimba kunyura hunyoro kuramba, zviri mukati hazvisi nyore kuunganidza, uye iyo capsule shell haisi nyore kukanganisa, kuita brittle, uye kuoma.
★ Hapana njodzi yekusangana-kusangana, hapana kupindirana, kugadzikana kwepamusoro, sezvo hydroxypropyl methylcellulose iine cellulose derivative, hapana njodzi yekuyambuka-inobatanidza kuita kweprotein zvinhu mugelatin.
★ Zvido zvakaderera zvekuchengetedza mamiriro:
Iyo inenge isina brittle munzvimbo yakaderera yehunyoro, ine kugadzikana kwakanaka pakupisa kwakanyanya, uye capsule haina kukanganisa.
★ Uniform zviyero uye kuenderana kwakanaka:
Inoshanda kune yenyika pharmacopoeia zviyero, chimiro, saizi, chitarisiko uye nzira yekuzadza yakaenzana negelatin hollow capsules, uye hapana chikonzero chekutsiva midziyo uye zvikamu.
★ Isiri yemhuka sosi, hapana njodzi inogona kuitika yekukura kwehomoni kana zvinodhaka zvakasara mumuviri wemhuka.
Hydroxypropyl methylcellulosemacapsules asina chinhu akasiyana kubva kune echinyakare gelatin capsules isina chinhu. Iwo hydroxypropyl methylcellulose (HPMC) yakagadzirwa nehuni pulp. Kuwedzera kune zvakanakira iyo yakachena yakasikwa pfungwa, hydroxypropyl methylcellulose capsules isina chinhu zvakare Inogona kuvandudza kunyura uye kugaya kweprotein, mafuta uye makhahydrates, uye ine hunyanzvi hwakanakira uye hunhu izvo zvechinyakare gelatin hollow capsules hazvina. Nekuenderera mberi kwekusimudzira kwekuziva kwekuzvitarisira kwevanhu, kukura kwezvinomera, kubviswa kwechirwere chemombe inopenga, chirwere chetsoka-ne-muromo pahutano hwevanhu, uye pesvedzero yechitendero nezvimwe zvinhu, zvakachena zvakasikwa uye zvinomera-based capsule zvigadzirwa. ichave inotungamira kutungamira kwekusimudzira iyo capsule indasitiri. .
