Twin ntsia hlau extruders yog dav siv rau kev hloov kho lub cev ntawm polymers, thiab tseem tuaj yeem siv rau extrusion ntawm molded khoom. Nws cov yam ntxwv pub mis zoo dua, thiab nws muaj kev sib xyaw zoo dua, qhov cua, thiab kev tu tus kheej ua haujlwm dua li ib qho ntsia hlau extruder. Los ntawm kev sib xyaw ua ke ntawm cov ntaub ntawv sib txawv ntawm cov ntsiab lus ntawm cov ntsia hlau, ntxaib-ntsia hlau extruder nrog kev ua haujlwm sab hauv tsim hauv daim ntawv ntawm lub tsev thaiv tuaj yeem siv rau hauv cov hauv qab no.
- Kev tsim cov masterbatch
Kev sib xyaw ntawm cov khoom siv yas thiab cov khoom siv ntxiv yog cov tswv batch. Additives muaj xws li pigments, fillers thiab functional additives. Lub ntxaib-ntsia hlau extruder yog cov cuab yeej tseem ceeb ntawm cov kab ntau lawm masterbatch, siv rau homogenization, dispersion thiab sib tov ntawm additives nyob rau hauv lub polymer matrix.
- Kev hloov kho sib xyaw
Muab qhov zoo tshaj plaws sib xyaw ua haujlwm ntawm matrix thiab additives, fillers. Cov iav fiber ntau yog cov khoom siv tseem ceeb tshaj plaws, tab sis lwm cov fibers kuj tuaj yeem ua ke nrog cov khoom siv polymer. Los ntawm kev ntxiv cov fibers thiab sib txuas nrog cov polymers, cov khoom siv nrog lub zog siab thiab kev cuam tshuam siab tuaj yeem tau txais, thiab tib lub sijhawm, qhov hnyav thiab tus nqi tuaj yeem txo.
- Tshem tawm
Vim yog kev sib nrig sib txuas ntawm ob lub ntsia hlau, cov txheej txheem shearing ntawm cov khoom ntawm lub meshing txoj hauj lwm tsis tu ncua hloov cov txheej txheej ntawm cov khoom thiab txhim kho cov pa tawm, yog li ntawd cov ntxaib-ntsia hlau extruder muaj kev ua tau zoo dua li cov ntsia hlau ib leeg. extruder. Kev ua haujlwm tawm.
- Direct extrusion
Lub ntxaib-ntsia hlau extruder tuaj yeem sib xyaw ua ke thiab extrusion molding. Los ntawm kev siv lub taub hau tshwj xeeb thiab cov khoom siv hauv qab kom tsim nyog, nws tuaj yeem tsim cov khoom tiav hauv qhov ua tau zoo dua, xws li cov yeeb yaj kiab, daim hlau, cov kav dej, thiab lwm yam. Direct extrusion tuaj yeem tshem tawm cov kauj ruam ntawm kev ua kom txias thiab pelletizing thiab reheating thiab melting, thiab cov khoom yuav raug thermal stress thiab shear stress tsawg. Tag nrho cov txheej txheem tuaj yeem txuag lub zog thiab cov qauv tuaj yeem hloov kho tau yooj yim.
