Peb cov cav tov muaj cov qauv tsim qauv uas yooj yim rau customization. Ua ntej, cov cav tov tau nruab nrog ntau yam extruders. Txhua extruder yog lub luag hauj lwm rau melting thiab extruding ntau hom khoom yas. Piv txwv li, ib qho extruder yuav raug siv los ua txheej txheej sab hauv ntawm PE-RT cov khoom, thaum lwm tus extruder yog siv los ua cov txheej txheem sib txawv ntawm cov polymer uas xav tau rau txheej txheej.
Cov extruders txuas nrog co-extrusion tuag. Qhov kev tuag no yog qhov tseem ceeb ntawm cov txheej txheem ntawm cov yeeb nkab multilayer, qhov twg cov txheej txheem sib txawv ntawm cov yas converge. Cov tuag yog tsim los tswj cov tuab thiab cov duab ntawm txhua txheej, kom ntseeg tau zoo ib yam thoob plaws tag nrho ntev ntawm cov yeeb nkab multilayer.
Peb kuj tau nruab nrog lub tshuab cua txias. Tom qab cov yeeb nkab multilayer tawm ntawm qhov tuag, nws yuav tsum tau txias sai sai kom khov cov txheej. Peb lub tshuab cua txias ua ke ua ke cov dej txias thiab cua txias kom ua tiav qhov no. Cov dej txias yuav pab txo qis cov yeeb nkab kub sai, thaum cua txias ua kom tiav cov txheej txheem txias thiab tiv thaiv kev sib tsoo lossis deformation.
Lwm qhov tseem ceeb yog kev tswj hwm qhov system. Peb cov cav tov tau nruab nrog cov kev tswj xyuas siab heev uas tso cai rau cov neeg ua haujlwm saib xyuas thiab kho cov txheej txheem tsim khoom raws sijhawm. Lawv tuaj yeem tswj cov extruder ceev, cov khoom kub, thiab tuag siab. Qhov kev tswj hwm qib no ua kom muaj qhov tseeb thiab siab - zoo ntawm cov kav dej ntau.
