Extrusion Granulation (一) - Muab kauv Extrusion Granulation
Muaj ob hom ntsia hlau extrusion granulator: Pem hauv ntej extrusion thiab sab extrusion. Muaj qee qhov sib txawv ntawm cov ntsia hlau ncej thiab cov kab hniav ntawm ob tus extrusion ntsia hlau kaum sab xis, thiab sab kev extrusting ntsia hlau kaum yog loj dua. Loj dua. Feem ntau, txoj kab uas hla ntawm cov khoom siv ua ntej loj dua, thiab lub hardness kuj siab dua. Cov cheeb tsam me me tuaj yeem tsim los ntawm sab extrusion, tab sis lub hardness yog phem dua li ntawm extrusion. Nws yog tsim nyog sau cia tias cov khoom siv tau yooj yim kom ua kom sov thaum ua ntej extrusion, thiab kev tshwj xeeb yuav tsum tau them rau cov ntaub ntawv uas yog cua sov rhiab lossis tshav kub nplaum hauv cov hmoov.
Feem ntau cov granulator yog nruab nrog kev hloov pauv hniav rau txhuam cov phaj phaj adhesion. Cov hniav cov hniav nruab hauv ob qhov pib ntawm muab kauv extruder gorsuler granulators yog txawv, thiab pem hauv ntej extruder hom presipt txuas ntxiv lossis kiv cua hniav; Sab sab exusion hom siv lub consical lub tog raj kheej lossis txhuam hniav. Cov khoom siv tau zoo zuj zus los ntawm cov chaw sib txuas ib puag ncig mus rau txoj kev sib cav, yog li ntawd cov kev taw qhia tawm ntawm cov khoom yog ntawm txoj cai sib dhos. Vim nws cov phaj orifle nyias, cov tau txais cov ntom ntom ntom ntom ntom ntom yog qis dua, tab sis kev ua haujlwm tau ntau dua. Cov duab thiab qhov loj me ntawm cov qhov me me raug txiav txim siab raws li kev tsim khoom. Yog hais tias cov hais nrog kev ua kom muaj zog dua yuav tsum tau npaj, cov tuab ntawm tus sib cais thiab lub zog ntawm lub cev muaj zog yuav tsum nce ntxiv.
Lub ntsia hlau Extruder granulator siv cov nplawm ntawm lub raj ntawm cov khoom muag thiab thauj nws mus rau lub aperture, yuam kev extrusion los ntawm lub qhov me me mus rau granulate me me. Lub tshuab tau muab faib ua peb qhov chaw ua haujlwm, thaj chaw pub noj mov, nias thaj chaw thiab thaj chaw.
Cov cheeb tsam pub mis yog tsim los ntawm kev pub mis thiab lwm qhov chaw, cov khoom siv muag khoom muag rau hauv cov khoom muag muag, tom qab ntawd, cov khoom muag muag tuaj yeem sib xyaw ua key. Tom qab cov khoom muag muag nkag tau cov zeem muag kauv, cov khoom muag muag tau xa mus rau thaj chaw hauv kev los ntawm kev kauv. Kev hloov Axis tuaj yeem muab faib ua ib qho kev sib hloov axis thiab ob npaug tsim Axis, thiab cov nplais uas tsim los ntawm kev sib hloov Axis muaj ntau dua ntom ntom. Ob chav ntsug teb cov roj muaj peev xwm zam tau rau cov tub nres nkoj pub mis, ua kom cov khoom siv hauv qab thiab muaj peev xwm loj.
Hauv thaj chaw ua ke, cov pa ntawm cov koog vov yog compressed thiab escapes. Txhawm rau ua kom cov cua khiav kom zoo thiab zam qhov tsis sib haum ntawm cov khoom uas tau los ntawm huab cua uas twb muaj lawm, lub qhov sab yog feem ntau nruab rau hauv thaj chaw compression.
Nyob rau hauv lub chaw extrusion, cov ntsia hlau ncej yog tsim raws li cov nyiaj yuav tsum tau, thiab nws txoj haujlwm tseem ceeb yog thauj khoom, feem ntau yog nyob rau hauv lub hau ntswj
Nws yog siv los tawm ntawm qee qhov chaw nruab nrab ntawm tus kauv tus kauv ncej thiab tsim lub qhov phaj, uas yog conducive rau qhov compression ntawm cov khoom. Raws li cov lus rheological ntawm cov khoom (xws li viscosity, elasticity, deformation thiab formatity ntawm cov khoom siv tom qab compression, thiab qis dua tus vice versa. Raws li tib qho kev mob, cov khoom ntom ntom nce nrog kev nce ntawm cov kauv ntawm cov kauv kab thiab cov tshuab ua kom muaj qhov siab dua muaj qhov chaw siab dua. Kev Kub Siab Dua Extrusion Gran Kev Siv Khoom Siv tsis muaj peev xwm siv tau, ntawm qhov kev siv hluav taws xob, kev ua haujlwm tsis zoo, kev siv hluav taws xob tsis zoo, cov khoom siv tsis zoo.
Yog tias muaj ib qho cai tau, thov hu rau peb, Shh Muaj cua.
