Dab tsi yog qhov sib txawv ntawm extrusion thiab coextrusion? Tseem pom tseem ceeb rau plastics scufacturing

Extrusion thiab coextrusion yog ob cov txheej txheem ntau lawm siv los ua cov khoom lag luam yas, thiab siv ntau yam khoom sib txawv los ua ke rau cov khoom sib txawv rau hauv ib qho khoom siv lossis encapsulated tus qauv . Qhov no tuaj yeem txhim kho cov khoom lag luam, thaum muaj qhov zoo tshaj plaws rau cov ntaub ntawv ntawm ntau cov khoom .

Cov Ntsiab Lus Tseem Ceeb:
Dab tsi yog qhov sib txawv ntawm extrusion thiab coextrusion? Tseem Ceeb Cov Kev Raug Yas
Cov Txheej Txheem Txheej txheem cej luam:

Extrusion: Hauv cov txheej txheem txheem tsim qauv, cov khoom siv yas ua tiav rau cov khoom siv txuas ntxiv rau ib qho kev ua lag luam
Kev sib xyaw ua haujlwm ntau ntxiv rau cov khoom lag luam sib xyaw ua ke
Siv khoom siv:

Extrusion: Siv ib hom khoom yas yas . Cov txheej txheem yooj yim thiab raug nqi los tsim cov khoom lag luam tsis zoo .
Kev sib tw: siv ntau cov ntaub ntawv, suav nrog ntau hom plastics lossis tseem sib xyaw ua ke ntawm cov qauv nplaum lossis cov khoom lag luam sib xyaw rau cov khoom lag luam ntawm cov khoom lag luam ntau ntxiv thiab cov khoom lag luam.
Chaw Thov:

Extrusion: feem ntau yog siv rau cov khoom lag luam xws li cov khoom siv yas thiab profiles {} Nws tsim nyog rau cov ntaub ntawv uas xav tau .
Kev Siv Khoom Siv Ua Ntej: Siv rau cov ntawv thov uas xav tau ntau cov khoom noj ntim khoom, cov khoom siv hluav taws xob nrog cov txheej txheem sib txawv thiab kev kho mob nrog cov txheej txheem sib txawv nrog cov txheej txheem
Qhov zoo thiab txwv:

Extrusion:
Cov txiaj ntsig: Yooj yim, muaj txiaj ntsig zoo, thiab cov khoom lag luam siab ntau rau cov khoom siv ib leeg-cov khoom siv {2}
Txwv: Txwv rau cov khoom siv ib leeg nkaus xwb, yuav tsis tau raws li qhov yuav tsum tau siv cov kev siv nyuaj ntxiv.
Coextrusion:
Cov txiaj ntsig: kev muaj peev xwm ua ke los sib txuas los txhim kho kev ua haujlwm thiab kev ua tau zoo} Qhov no suav nrog kev txhim kho cov khoom lag luam, lub zog, thiab ua kom zoo nkauj.
Txwv: nyuaj thiab kim vim qhov xav tau rau ntau tus extruders thiab meej tswj ntawm cov khoom ntws thiab txheej .
Khoom siv thiab teeb tsa:

Extrusion: Yuav tsum muaj extruder, tuag, thiab txias txias ciracator system. Cov teeb tsa tau yooj yim thiab tuaj yeem kho tau yooj yim rau siab heev.
Kev rho tawm: Yuav tsum muaj ntau cov extruders, txhua tus tau mob siab rau cov khoom sib txawv thiab yuav tsum tau tswj cov khoom siv kom ntseeg tau tias yog cov khoom siv pov tseg kom yog cov khoom lag luam kom zoo thiab ua kom tiav.
Zoo thiab ua tau zoo:

Extrusion: Ua cov khoom lag luam tsis sib xws nrog cov khoom siv tsis sib xws . Txawm li cas los xij, nws qhov kev ua tau zoo rau tib cov khoom siv.
COExtrusion: tuaj yeem tsim cov khoom lag luam nrog cov khoom siv tau yooj yim, hloov kho lub zog, hloov khoom siv rau cov ntawv thov ntau dua.
Hauv cov ntsiab lus, extrusion yog qhov yooj yim thiab cov khoom lag luam zoo dua rau cov khoom lag luam ntau ntxiv thiab cov khoom siv sib txuas ntawm cov khoom lag luam uas yog tsim .
