HPMC capsule, nyob rau hauv lub rooj sab laj kuj tau qhia, xws li HPMC nta thiab siv, thiab lwm yam khoom.
Hauv luv luv, peb tab tom tham txog qhov zoo ntawm HPMC capsule, tsis hais ntau, muaj plaub yam tseem ceeb: ib qho yog los ntawm cov nroj tsuag, ob yog tsis kis kab mob tsiaj; Qhov thib peb yog ua kom tau raws li cov kev xav tau ntawm cov neeg tsis noj nqaij tsis ua txhaum kev cai dab qhuas; Plaub, cov ntsiab lus noo noo tsawg, tsis yooj yim rau kev cuam tshuam los ntawm cov av noo, haum rau sau cov khoom hygroscopic lossis noo noo; HPMC muaj kev ruaj ntseg zoo thiab teeb meem kev sib raug zoo yam tsis muaj kev sib txuas.
Cov no yog tag nrho cov ntaub ntawv tseem ceeb los pab nkag siab txog HPMC capsules. Txawm li cas los xij, yog tias tsuas yog saib cov ntaub ntawv no yuav ua rau tsis meej pem, vim tias cov ntawv no rau ntau lub hom phiaj, HPMC capsule yuav hais tau zoo heev, qee zaus yuav muaj qee qhov kev taw qhia tsis raug. Peb tsom peb cov kev mob siab rau cov teeb meem uas yooj yim tsis quav ntsej lossis dag.
(1) Ib qho yuam kev: siab toughness, tsis tawg tawg
Yog hais tias koj tsuas yog hais tias lawv toughness siab, tsis nkig tawg, tsuas yog hais tsis kam. Tab sis piv rau gelatin capsules, nws yog qhov tsis zoo. Nrog ob lub ntsiab lus los ua pov thawj: ua ntej ntawm tag nrho cov, qhov yuav tshwm sim ntawm gelatin capsule yog siab dua HPMC capsule, kev sab laj lwm tus neeg, txawm tias HPMC capsule hais tias txawm zoo npaum li cas los kuj tsis kam hais qhov no zoo dua gelatin: qhov thib ob, gelatin capsule hauv lub capsule lub cev sib cais yuav pib tsuas yog deflate qhov tshwm sim, tab sis HPMC capsule feem ntau puas los yog tawg. Nws yog qhov yooj yim kom pom qhov twg yog qhov zoo dua li lwm tus. Kev paub ntawm tus kheej, txawv manufacturers capsule zoo tuaj yeem hnov los ntawm tes, zoo toughness, muag muag zoo dua. Tus kheej, quali-V yog superior rau vcaps ntxiv.
(2) ob qho yuam kev: kev ruaj ntseg zoo heev
Kev ruaj ntseg ntawm gelatin capsules tsis tas yuav sawv. Muaj tseeb, gelatin capsules muaj qee qhov teeb meem, uas txhais tau hais tias gelatin tau yoog rau qee yam tshuaj. Hauv lwm lo lus, HPMC tsis yog khoom siv thoob ntiaj teb, kuj tseem muaj qee qhov txwv tsis pub siv. Cia peb hais tias txhua tus muaj nws qhov zoo.
(3) Ib qho kev xav tsis zoo yog tias HPMC tsuas yog cov khoom siv raw
Qhov tseeb, HPMC capsule kuj yog ntau yam khoom siv npaj, muaj pes tsawg leeg yog complex, tsis yog ib leeg. Piv txwv li, HPMC, carrageenan, gellan gum, SDS thiab lwm yam ntaub ntawv kev npaj, ntawm chav kawm, tsis muaj shading titanium oxide, zoo nkauj tab sis kuj pigment, tej zaum yuav muaj ib co polishing neeg sawv cev.
(4) Cov teeb meem uas tsis tuaj yeem tsis quav ntsej - lub sijhawm ntev ntawm kev sib tsoo thiab qhov sib txawv ntawm tus kheej loj
Thawj tiam ntawm HPMC capsule, feem ntau ntawm rupture ntawm 10 thiab 30 feeb, tsis txhob siv cov tshuaj ntsiav no rau kev npaj tawm sai. Rau tiam thib ob ntawm vcaps ntxiv, lub sijhawm tawg yog feem ntau ntawm 3 thiab 15min. Raws li kuv qhov kev sim, nyob rau hauv hydrochloric acid nruab nrab, nws feem ntau yog li ntawm 4 mus rau 7 feeb, uas yog me ntsis sai dua li lwm cov xov xwm, tab sis nws kuj siv sij hawm 8 mus rau 10 feeb kom tawg. Txawm tias nyob rau tiam thib ob, tus neeg sib txawv tsis tuaj yeem tsis quav ntsej, thiab qee zaus yuav muaj qhov tshwm sim ntawm tus kheej 15 feeb.
Tau kawg, HPMC capsule txheej txheem kuj tseem ua kom zoo dua qub, txhim kho kev sib txawv ntawm tus kheej, nce tus nqi ntawm kev sib tsoo yog qhov tseem ceeb heev.
(5) Yooj yim tsis quav ntsej qhov teeb meem - ntsev hauv qhov nruab nrab dissolving
Cov poov tshuaj ions nyob rau hauv qhov nruab nrab dissolution yuav txuas nrog cov pos hniav gellan hauv cov tshuaj ntsiav, txo cov solubility ntawm HPMC capsule, uas ua rau qeeb disintegration. Qhov no yog ib yam uas yuav tsum tau ceev faj thaum ua kev tshawb fawb, vim hais tias poov tshuaj phosphate muaj ntau heev nyob rau hauv lub configuration ntawm leaching media.
(6) Kev sau npe hauv tsev
Cov tshuaj ntsiav no, txawm li cas los xij, zoo li qhov tsis zoo, tab sis qhov tseeb, raws li thev naus laus zis tau txhim kho thiab tus nqi qis dua, cov teeb meem no tau raug daws. Txawm li cas los xij, HPMC capsule yuav tsum tau hloov gelatin capsules sai sai vim nws cov txiaj ntsig tseem ceeb xws li kev pheej hmoo tsis muaj kev nyab xeeb, tsim nyog rau kev lag luam Muslim thiab cov neeg tsis noj nqaij.
