Tus qauv ntawm lub extruder
Apr 01, 2022
Cov qauv ntawm extruder:
1. Lub feeder yog los xyuas kom meej cov khoom noj thiab ruaj khov thiab kho tus nqi noj raws li tus nqi tam sim no ntawm lub tshuab extrusion. Feem ntau, electromagnetic ceev tswj lub cev muaj zog los yog lub zaus hloov pauv yog siv rau kev tswj ceev kom hloov pauv tus nqi noj ntawm lub feeder. Lub qhov hluav taws xob ntawm qhov pub noj hopper feem ntau yog pub los ntawm cov ntsia hlau auger mus rau seem extrusion thiab puffing.
2. Cov kab noj hniav nthuav dav yog tsim los ntawm cov ntsia hlau, lub tes tsho, cov qauv, daim npav pob txha, thiab lwm yam. Cov ntsia hlau thiab lub tes tsho ntawm lub tes tsho yog sib xyaw ua ke hauv cov ntu, cov qib ntawm compression tuaj yeem hloov kho raws li hom thiab cov kev xav tau ntawm cov khoom siv extruded, thiab qhov expansion degree ntawm extruded pub tuaj yeem hloov tau.
3. Lub tshuab puffing tau muab faib ua 3 ntu nyob rau hauv cov nqe lus ntawm kev sib tsoo degree raws li kev ua haujlwm thiab txoj haujlwm:
Kev pub khoom noj: seem no muaj cov ntsia hlau loj loj, uas feem ntau xa thiab compresses cov khoom kom cov khoom ntim rau hauv qhov zawj.
Compression seem: Cov ntsia hlau zawj ntawm ntu no hloov ntawm qhov tob mus rau qhov ntiav raws li cov khoom txav txav mus rau compress cov khoom.
Extrusion seem: cov ntsia hlau zawj yog ntiav, lub suab maj mam ua me, lub zog extrusion tuaj yeem ncav cuag 3.0-10Mpa, thiab qhov kub tuaj yeem ncav cuag 120-150 degrees Celsius. Cov ntu no muaj qhov siab tshaj plaws thiab qhov kub siab tshaj plaws, yog li kev hnav ntawm cov ntsia hlau thiab lub tes tsho ntawm tes kuj yog qhov hnyav tshaj plaws.
Lub qhov hluav taws xob ntawm seem extrusion yog ib qho qauv. Cov duab ntawm tus qauv yog tsim los nrog qhov sib txawv tuag raws li qhov xav tau ntawm cov khoom sib txawv. Cov khoom yog extruded los ntawm qhov tuag qhov ntawm lub template thiab nkag mus rau hauv cov huab cua. Lub siab thiab kub poob qis heev, ua rau nws lub ntim kom nthuav dav thiab ya raws sai sai evaporation, lub cev qhuav dej thiab solidification ua cov ntaub ntawv extruded.
