Kev piav qhia txog cov yam ntxwv zoo thiab kev tshuaj xyuas cov yam ntxwv cuam tshuam rau hauv HIGH SHEAR lub tshuab sib tov Kev ua kom cov hmoov av
Cov thev naus laus zis High Shear Mixer Granulation siv dav hauv kev npaj tshuaj khov kho. Cov thev naus laus zis no feem ntau sib tov cov khoom siv raw thiab exCipcov khoom sib npaug zos los tsim cov khoom me me ntawm 180-2000 μ m, uas yog siv rau hauv cov txheej txheem downstream xws li kev nias ntsiav tshuaj, kev sau tshuaj ntsiav, thiab kev ntim khoom me me. Kev siv cov txheej txheem ntub dej granulation yog qhov tseem ceeb rau kev muab cov khoom zoo thiab tsim nyog downstream. Cov khoom ntawm cov khoom me me cuam tshuam rau cov yam ntxwv zoo tseem ceeb ntawm cov khoom, xws li tus nqi yaj, qhov sib txawv ntawm qhov hnyav ntsiav tshuaj (qhov sib txawv ntawm qhov ntim khoom), thiab lwm yam. Feem ntau, peb tuaj yeem soj ntsuam cov khoom me me raws li cov cim qhia lub cev xws li kev faib tawm qhov loj me ntawm cov khoom me me, porosity, cov dej noo, thiab kev ntws tau. Lub hom phiaj loj me me ntawm cov khoom me me yog hais txog feem pua ntawm cov khoom me me uas ua tau raws li qhov xav tau ntawm cov khoom me me hauv cov khoom kawg rau tag nrho cov khoom me me, uas tuaj yeem ntsuas los ntawm kev tshuaj ntsuam, laser, thiab cov duab. Raws li tus qauv kev lag luam JB / T 20015, tus qauv kev ntsuas kev ua tau zoo rau cov khoom sib xyaw ntub dej yog tias tus nqi ntawm cov hmoov txhuv nplej siab, dextrin, thiab hmoov qab zib hauv qhov sib piv 3: 2: 1 tom qab ziab yuav tsum tsis pub tsawg dua 75% hauv qhov ntau ntawm 180-2000 μ m. Cov lag luam lees paub qhov loj me ntawm cov khoom siv ntub dej raws li cov txheej txheem xav tau, thiab qhov loj me ntawm cov khoom siv thiab qhov nrawm ntawm cov khoom siv yog raws li cov khoom xav tau tshwj xeeb. Kev faib tawm ntawm cov khoom siv piav qhia txog qhov sib piv ntawm cov khoom siv ntawm ntau qhov ntau thiab tsawg hauv ib lub kaw lus khoom siv, thaum qhov degree dispersion yog ntsuas los ntawm qhov dav ntawm kev faib tawm ntawm cov khoom siv. Kev faib tawm ntawm cov khoom siv yog tau los ntawm cov txheej txheem suav lej raws li cov txiaj ntsig ntawm kev tshawb pom qhov loj me ntawm cov khoom siv. Txawm tias qhov loj me ntawm cov khoom siv yog tib yam, tej zaum tseem yuav muaj qhov sib txawv tseem ceeb hauv kev faib tawm ntawm cov khoom siv. Rau feem ntau cov tshuaj, peb nyiam qhov me me ntawm cov khoom siv hauv qhov ntau thiab tsawg ntawm cov khoom siv uas xav tau kom ntseeg tau tias muaj kev sib xws hauv cov nyhuv yaj tshuaj. Qhov dav ntawm kev faib tawm ntawm cov khoom siv feem ntau yog siv los ntsuas qhov degree ntawm kev faib tawm ntawm kev faib tawm ntawm cov khoom siv. Txoj kev xam yog raws li nram no: (1) Hauv qhov sib npaug: D90- lub cheeb ntawm cov khoom me me sib raug rau qhov suav ntawm qhov loj ntawm cov khoom me me mus rau loj txog 90% ntawm tag nrho, μm; D10- lub cheeb ntawm cov khoom me me sib raug rau qhov suav ntawm qhov loj ntawm cov khoom me me mus rau loj txog 10% ntawm tag nrho, μm; D50- lub cheeb ntawm cov khoom me me sib raug rau qhov suav ntawm qhov loj ntawm cov khoom me me mus rau loj txog 50% ntawm tag nrho, μm. Qhov loj dua qhov dav, qhov sib txawv ntawm qhov loj ntawm cov khoom me me thiab qhov tsis sib xws; Ntawm qhov tod tes, nws sib xws ntau dua. Daim duab 1 qhia txog qhov sib txawv ntawm qhov dav ntawm cov khoom me me uas tau npaj siv cov khoom siv raw tib yam thiab cov txheej txheem sib txawv. Nws tuaj yeem pom tias txawm hais tias qhov loj ntawm cov khoom me me ntawm 180-2000 μ m zoo sib xws, qhov sib txawv ntawm qhov dav ntawm cov khoom me me yog qhov tseem ceeb (qhov nkhaus xiav muaj tus nqi Span me dua, qhov nkhaus daj muaj tus nqi Span nruab nrab, thiab qhov nkhaus txiv kab ntxwv muaj tus nqi Span loj dua). Yog li ntawd, kev xaiv tus nqi Span tsim nyog raws li cov txheej txheem xav tau yog qhov tseem ceeb hauv kev ntsuam xyuas qhov ua tau zoo ntawm kev ua kom ntub dej.
