Los ntawm qhov kev xav ntawm kev tsim cov khoom yas, lub tshuab extrusion tshuab yog siv rau inflating, txias, thiab shaping lub parison, thaum muab tus tsim qauv xav tau thiab loj.Lub tshuab extrusion tshuab muaj cov yam ntxwv hauv qab no.

(1) Extrusion tshuab moulding pwm, tshwj tsis yog cov pwm tshwj xeeb xws li cov khoom siv ob phab ntsa, tsuas muaj cov poj niam pwm kab noj hniav thiab tsis muaj txiv neej pwm.Piv nrog rau cov pwm siv nyob rau hauv lwm yam khoom yas, cov qauv yog ntau yooj yim.

(2) Txij li cov qauv pwm tsis muaj txiv neej pwm, nws tuaj yeem ua rau cov khoom siv yas nrog qhov tob tob thiab cov duab nyuaj.

(3) Lub pwm kab noj hniav tsis muaj dej ntws ntws, thiab cov pwm raug kaw tom qab lub parison nkag mus rau hauv pwm.Lub parison yaj cia siab rau compressed cua nthuav dav kom puv cov kab noj hniav.

(4) Piv nrog rau kev txhaj tshuaj pwm, extrusion tshuab pwm kab noj hniav bears qis dua.Cov khoom siv hnyav tuaj yeem siv los ua cov pwm, thiab cov kab noj hniav tsis tas yuav tsum tau ua kom tawv.Tus nqi pwm yog tus nqi qis.

(5) Kev tsim khoom tsis tu ncua, kev ua haujlwm siab ntau lawm, thiab cov khoom siv ntev tuaj yeem tsim khoom;

(6) Cov khoom siv sib txawv tuaj yeem tsim tau;

(7) Ua ke nrog lwm cov khoom siv, nws tuaj yeem ua tiav kev ua tiav ntawm cov txheej txheem sib txawv.Piv txwv li, lub tshuab kos duab thiab lub tshuab calendering koom tes los tsim cov yeeb yaj kiab;

(8) Lub taub hau extruder thiab pelletizer tuaj yeem koom tes rau pelletize;

(9) Lub cheeb tsam me me thiab qhov chaw tsim khoom huv si.
