Extrusion Tshuab Ntsia Hlau

Lub tshuab Extrusion tshuab ntsia hlau yog qhov tseem ceeb ntawm cov txheej txheem extrusion, ua si ib lub luag haujlwm tseem ceeb hauv kev thauj, melting, thiab shaping cov khoom siv tau ua tiav. Hauv tsab xov xwm no, peb yuav tshawb txog cov qauv, cov ntsiab cai ua haujlwm, thiab kev siv cov tshuab luam yeeb.

Cov tshuab Extrusion tshuab ntsia hlau yog feem ntau ua los ntawm cov khoom siv zoo, cov khoom siv ruaj khov xws li cov hlau nrawm lossis cov cuab yeej hlau. Nws yog tsim ntawm tus pas nrig cylindrical nrog ib lub siab khaus uas cua ncig nws. Lub hau ntswj yog tsim kom haum nruj nreem tsis pub dhau lub thoob ntawm cov tshuab extrusion, nrog qhov kev tshem tawm me me kom tso cai rau kev txav ntawm cov khoom.

Tus txheej txheem ua hauj lwm ntawm Extrusion Tshuab Ntsia Hlau tuaj yeem yog sau ua ntej: Raws li cov ntsia hlau tig, nws yog cov khoom siv los ntawm kev pub mis xaus rau lub tshuab. Cov dav hlau helical ntawm cov ntsia hlau thawb cov khoom siv rau pem hauv ntej, thaum lub sijhawm kub tsim los ntawm lub tshuab melts cov khoom thiab hloov nws mus rau hauv lub xeev viscous.

Cov tshuab Extrusion tshuab ntsia hlau yog tsim nrog ntau ntu uas ua cov haujlwm tshwj xeeb. Cov cheeb tsam pub mis, nyob rau thaum pib ntawm lub hau ntswj, yog lub luag haujlwm rau rub hauv cov khoom thiab compressing nws. Qhov chaw ua ke compression ua raws, qhov uas cov khoom siv tau compressed thiab rhuab los ntawm kev sib txhuam thiab cov cua sov tsim los ntawm lub tshuab.

Lub cheeb tsam melting los tom ntej, qhov twg cov khoom siv tau tag nrho cov khoom thiab sib xyaw. Ntu ntawm cov ntsia hlau ib txwm tsim nrog lub davhlau ntxig kom muaj kev ua kom haum thiab txhawb kev ua kom zoo nkauj thiab sib xyaw ntawm cov khoom siv. Thaum kawg, lub meterting cheeb tsam tswj tus dej ntws thiab siab ntawm cov khoom uas nws tau thawb ntawm kev tuag.

Lub tshuab Extrusion tshuab ntsia hlau yog siv dav hauv ntau yam kev lag luam, suav nrog cov yas, roj hmab, thiab ua zaub mov noj. Hauv kev lag luam plastics, lub hau ntswj yog siv rau cov pellets yas lossis cov pob zeb ua kom zoo nkauj, xws li cov kav dej, khoom siv, lossis cov ntawv txheeb. Hauv kev lag luam roj hmab, cov ntsia hlau yog ua haujlwm rau txheej txheem roj hmab teb rau hauv ntau yam khoom, zoo li cov ntsaws ruaj ruaj, gaskets, lossis cov log tsheb. Hauv kev lag luam khoom noj khoom haus, cov ntsia hlau raug siv los mus muab cov khoom noj khoom haus extrude, xws li khob noom cookie lossis pasta.

Kev tu xyuas kom zoo thiab kev saib xyuas ntawm cov tshuab luam ntawv extrusion yog qhov tseem ceeb kom ntseeg tau nws lub siab ntev thiab ua tau zoo. Kev tu thiab tshuaj xyuas kev tshuaj xyuas kom tshem tawm cov chaw seem lossis cov paug tsis huv uas yuav cuam tshuam rau cov txheej txheem extrusion. Tsis tas li ntawd, cov tshev mis rau kev hnav lossis kev puas tsuaj yog tsim nyog, thiab cov khoom hnav lossis cov khoom puas lawm.

Hauv kev xaus, lub tshuab Extrusion tshuab ntsia hlau yog qhov tseem ceeb hauv kev ua kom tiav, lub luag haujlwm rau kev xa khoom, melting, thiab shaping cov khoom siv tau ua tiav. Nkag siab txog nws cov qauv, ua haujlwm hauv paus ntsiab lus, thiab cov ntawv thov yog qhov tseem ceeb rau kev ua tiav thiab muaj kev phom sij zoo. Los ntawm kev saib xyuas kom zoo thiab saib xyuas, cov tuam ntxhab tuaj yeem xyuas kom muaj kev ua haujlwm ntev thiab kev ua tau zoo ntawm kev extrusion tshuab ntsia hlau.
