Lub synthesis ntawm bagged hmoov muaj ob peb kauj ruam tseem ceeb, xws li raw khoom pretreatment, sib tov txheej txheem, ziab thiab shaping, thiab ntim. Lub hom phiaj tseem ceeb yog los xyuas kom meej cov khoom muaj pes tsawg leeg, kev ruaj ntseg siab, thiab yooj yim ntawm kev cia thiab kev thauj mus los. Hauv qab no yog ib qho kev qhia luv luv ntawm cov txheej txheem synthesis.
1. Raw Material Pretreatment
Ua ntej, cov khoom siv raw ua tau raws li qhov xav tau ntawm purity thiab particle loj ntawm cov formulation yuav tsum raug xaiv, xws li cov khoom xyaw nquag, fillers, los yog excipients. Qee cov khoom siv raw yuav xav tau crushing, sieving, los yog premixing los xyuas kom meej uniformity nyob rau hauv lub tom ntej ua. Piv txwv li, cov ntaub ntawv hygroscopic yuav tsum tau ua ntej- khaws cia rau hauv qhov chaw qhuav lossis muaj cov khoom siv desiccant ntxiv.
2. Kev sib xyaw ua ke
Kev sib xyaw yog cov kauj ruam tseem ceeb hauv cov hmoov synthesis. Cov txheej txheem feem ntau suav nrog kev sib xyaw ua ke (xws li V-hom mixers thiab peb -dimensional motion mixers) lossis airflow mixing, uas siv lub cev ua haujlwm kom sib faib cov khoom sib txawv. Rau cua sov- cov ntaub ntawv rhiab heev, qhov sib tov kub yuav tsum tau tswj; rau siab - cov formulations precision, ib tug stepwise dilution txoj kev yuav siv tau los txhim kho kev sib tov uniformity.
3. Drying and Shaping: Yog tias cov ntaub ntawv raw muaj cov dej noo los yog cov kuab tshuaj, lawv yuav tsum tau muab tshem tawm los ntawm kev ziab kom qhuav, fluidized txaj kom qhuav, los yog lub tshuab nqus tsev kom qhuav kom cov hmoov flowability thiab cia ruaj khov. Qee cov hmoov yuav tsum tau granulation ntxiv (piv txwv li, qhuav lossis ntub granulation) los txhim kho qhov ntom ntom, tab sis cov hmoov ntim khoom feem ntau ntim ncaj qha rau hauv cov hmoov zoo.
4. Ntim thiab Kev Tshuaj Xyuas Zoo: Cov hmoov sib xyaw ua ke yuav tsum tau muab faib ua ntau ntau rau hauv cov dej noo- cov hnab pov thawj (xws li, aluminium- cov hnab yas sib xyaw lossis PE hnab) thiab ntim nrog cov pa roj tsis zoo xws li nitrogen kom ntev lub neej txee. Tom qab ntim khoom, yuav tsum muaj kev soj ntsuam nruj nruj, suav nrog kev tshuaj xyuas cov khoom, kev kuaj pom qhov loj me, txwv tsis pub microbial, thiab ntsuas cov dej noo kom ntseeg tau tias ua raws li cov qauv kev lag luam.
Cov txheej txheem synthesis rau cov hnab ntim cov hmoov yuav tsum tau hloov kho raws li daim ntawv thov tshwj xeeb (xws li, khoom noj khoom haus additives, tshuaj raw cov ntaub ntawv, los yog tshuaj intermediates) kom ua tiav cov hom phiaj ua tau zoo, nyab xeeb, thiab tswj tau.
