API Kev tshuaj ntsuam xyuas
Khoom siv
Hauv kev sib xyaw ntawm cov khoom siv raw thiab cov khoom nruab nrab, qhov loj me ntawm cov khoom sib txawv, thiab qhov zoo ntawm cov hmoov tsis sib xws, uas yog depreciated lossis txawm tsis lees paub.Vim tias cov ntsiab lus ntawm cov nroj tsuag fiber ntau tshaj tus qauv, tus nqi ntawm cov hmoov tshuaj tsis tuaj yeem txhim kho.Qhov luaj li cas ntawm cov tshuaj yog txawv, qhov loj ntawm cov tshuaj yog txawv, thiab cov specifications ntawm raw cov ntaub ntawv yog txawv.Muaj ze li ib txhiab yam.Cov kev xav tau nruj, tsis tuaj yeem ua kom puas, puas, xws li tshuaj ntsiav pellets raw khoom.
Cov txheej txheem ntau lawm
Raw khoom extraction - pom - crystallization - sib cais - ziab - sieving - puab ntim - txheej ntim
Extraction ntawm raw cov ntaub ntawv: Raws li cov solubility ntawm ntau yam nyob rau hauv Suav tshuaj ntsuab tshuaj nyob rau hauv cov kuab tshuaj, ib tug hnyav uas muaj solubility siab rau active Cheebtsam thiab tsis muaj solubility rau Cheebtsam uas tsis yuav tsum tau yaj yog xaiv, thiab cov txheej txheem ntawm dissolving lub active Cheebtsam. los ntawm cov ntaub so ntswg ntawm cov khoom siv tshuaj yog hu ua hnyav extraction.
Filtration: Filtration yog hais txog kev ua haujlwm ntawm kev sib cais cov khoom sib cais hauv cov roj los yog kua, siv cov khoom ntxeem tau (filter nruab nrab) kom dhau cov pa roj los yog kua hauv qhov kev ncua (filter slurry) (filtrate), cuam tshuam cov khoom siv ( lim residue) uas tuaj nyob rau hauv lub lim nruab nrab los tsim ib lub ncuav mog qab zib lim.
Crystallization: Thaum cov kua dej kub saturated txias, cov solubility ntawm cov kuab tshuaj txo qis thiab cov tshuaj ua supersaturated, yog li ntawd cov kua nplaum precipitates nyob rau hauv daim ntawv ntawm crystallization.
Kev sib cais: qhuav thiab ntub sib cais.
Kev ziab: Siv cov cua sov kom vaporize noo noo (nqus dej los yog lwm yam kuab tshuaj) hauv cov ntaub ntawv ntub dej, thiab siv cov cua los yog lub tshuab nqus tsev kom tshem tawm cov vaporized ya raws kom tau cov khoom qhuav.
Kev tshuaj ntsuam: Cov khoom yog txheeb los ntawm particle loj.
Ntim: tiav ntim.
Kev tshuaj ntsuam lub hom phiaj
Nyob rau hauv cov synthesis ntawm intermediates, lub particle loj ntawm cov khoom yog txawv, thiab cov fineness ntawm cov hmoov yog tsis sib xws, uas yog depreciated los yog txawm tsis kam.Cov khoom yog nplaum, adsorbed, soj ntsuam thiab thaiv, qhov saum npoo ntawm cov khoom siv, thiab cov khoom loj yuav tsum nruj me ntsis, thiab nws tsis tuaj yeem raug puas los yog puas, xws li cov khoom siv raw ntawm cov tshuaj ntsiav thiab pellets.
