Dab tsi yog qhov txawv ntawm gelatin capsule thiab tsob nroj capsule
1. Cov khoom siv sib txawv
Lub ntsiab tseem ceeb ntawm gelatin capsule yog tshuaj gelatin, uas los ntawm collagen nyob rau hauv cov tsiaj tawv nqaij, leeg thiab pob txha. Lub ntsiab tseem ceeb ntawm cov tshuaj ntsiav tshuaj yog 2-hydroxypropyl methylcellulose, uas feem ntau yog ua los ntawm cellulose npaj los ntawm cov nroj tsuag hydrolysis thiab etherification.
2. Qhov txawv txav
Qhov saum npoo ntawm HPMC capsule yog rougher dua li ntawm hollow capsule, thiab cov pob tshab thiab du nto yog me ntsis phem dua li cov gelatin capsule.
Gelatin hollow capsule yog lub plhaub capsule nrog cov xim tshwj xeeb thiab cov duab ua los ntawm gelatin ua cov khoom siv tseem ceeb.

Cov tshuaj ntsiav ua los ntawm hollow capsule tsis xav tau cov nplaum thiab ntau cov khoom ntxiv hauv cov txheej txheem tsim khoom, thiab yooj yim rau disintegrate thiab tso tawm hauv cov kua txiv hmab txiv ntoo. Piv nrog rau cov ntsiav tshuaj thiab tshuaj, nws tuaj yeem txhim kho bioavailability. Nyob rau tib lub sijhawm, nws muaj qhov zoo ntawm cov koob tshuaj raug, yooj yim nqa thiab siv, kev ruaj ntseg sealing thiab lwm yam.
