Yas extruder kuj raug cais raws li ib qho ntawm ntau yam ntawm cov tshuab yas. Raws li cov khoom ntws kev taw qhia ntawm lub taub hau tuag thiab lub kaum sab xis ntawm cov kab nruab nrab ntawm cov ntsia hlau, lub extruder tuaj yeem faib lub taub hau tuag rau hauv txoj cai kaum tuag thiab oblique kaum tuag.
Cov ntsia hlau extruder tso siab rau lub siab thiab shear quab yuam tsim los ntawm kev sib hloov ntawm cov ntsia hlau, uas tuaj yeem ua rau cov khoom tuaj yeem ua tiav cov yas thiab sib xyaw ua ke, thiab tom qab ntawd tsim los ntawm kev tuag.
Txheej txheem cej luam
Lub plhaub ntawm lub tshuab taub hau feem ntau yog kho ntawm lub fuselage nrog bolts. Cov pwm hauv lub taub hau tshuab muaj cov tub ntxhais tuav, thiab tom qab ntawd raug kho rau qhov chaw nres nkoj ntawm lub tshuab taub hau nrog cov txiv ntoo. Sab hauv ntawm cov tub ntxhais tuav tseem raug ntsia Lub pwm tub ntxhais, thiab qhov nruab nrab ntawm cov tub ntxhais pwm thiab cov pwm tub ntxhais lub rooj zaum muaj qhov, uas yog siv los hla cov tub ntxhais hlau. Raws li kev sib txawv ntawm cov txheej txheem pressurization, cov txheej txheem extrusion tuaj yeem muab faib ua ntu txuas ntxiv thiab sib cuam tshuam extrusion. Cov khoom siv nyob rau hauv lub qub yog ib tug ntsia hlau extruder, thiab cov khoom nyob rau hauv lub tom kawg yog ib tug plunger extruder. Ntawm no, ntsia hlau extruders tuaj yeem raug faib ua ib leeg-ntsia hlau extruders thiab ntau cov ntsia hlau extruders raws li tus naj npawb ntawm cov ntsia hlau.
Cov txheej txheem kev khiav hauj lwm ntawm cov ntsia hlau extruder yog tso siab rau lub siab thiab shear quab yuam tsim los ntawm kev sib hloov ntawm cov ntsia hlau, uas tuaj yeem ua rau cov khoom tuaj yeem ua tiav plasticized thiab sib xyaw ua ke, thiab tom qab ntawd molded los ntawm kev tuag; yog li qee zaum ib qho extruder tuaj yeem siv los ua kom tiav cov txheej txheem. Cov txheej txheem xws li kev sib xyaw, plasticizing thiab molding, thiab tom qab ntawd mus rau kev tsim khoom tiav. Tsis tas li ntawd, kev khiav hauj lwm mechanism ntawm lub plunger extruder feem ntau yog nyob ntawm lub plunger siab los ua ntej extrude cov khoom uas tau yav tas los plasticized los ntawm cov tuag kom ua tiav cov nyhuv molding. Tom qab cov khoom nyob rau hauv cov khoom ntim yog extruded, lub plunger yuav rov qab. Piv nrog rau kev ntxiv ib puag ncig tshiab ntawm cov khoom siv yas, kev ua haujlwm tom ntej yog nqa tawm. Cov txheej txheem tsim khoom no yog tsim los ntawm kev tsim khoom tsis tu ncua, thiab cov khoom siv tsis tuaj yeem ua tiav. Sib tov thiab sib tov. Tsis tas li ntawd, qhov kev tsim khoom no yuav tsum tau pre-plasticized. Yog li ntawd, txoj kev no feem ntau tsis siv hauv kev xyaum. Nws tsuas yog siv tau rau cov yas uas muaj cov dej tsis zoo lossis cov viscosity siab heev, xws li nitrocellulose plastics. Yam khoom yas molding ua.
Yas extruders tuaj yeem muab faib ua ntxaib-ntsia hlau extruders, ib leeg-ntsia hlau extruders, thiab tsawg-ntsia hlau extruders thiab ntsia hlau-tsawg extruders.
