Extrusion tshuab ntsia hlau

Lub tshuab extrusion ntsia hlau yog ib qho tseem ceeb ntawm cov txheej txheem extrusion, ua lub luag haujlwm tseem ceeb hauv kev thauj, yaj, thiab kho cov khoom ua tiav.Hauv tsab xov xwm no, peb yuav tshawb xyuas cov qauv, cov qauv kev ua haujlwm, thiab kev siv ntawm lub tshuab extrusion ntsia hlau.

Lub tshuab extrusion ntsia hlau feem ntau yog ua los ntawm cov khoom zoo, cov khoom siv ruaj khov xws li cov hlau kub ceev lossis cov cuab yeej hlau.Nws yog tsim los ntawm ib tug cylindrical pas nrig nrog ib tug helical davhlau uas cua nyob ib ncig ntawm nws.Cov ntsia hlau yog tsim kom haum nruj rau hauv lub thoob ntawm lub tshuab extrusion, nrog rau kev tshem tawm me me kom tso cai rau kev txav ntawm cov khoom.

Lub hauv paus ntsiab lus ntawm kev ua haujlwm ntawm lub tshuab extrusion ntsia hlau tuaj yeem ua tiav raws li hauv qab no: raws li cov ntsia hlau tig, nws xa cov khoom siv los ntawm kev pub mis mus rau qhov kawg ntawm lub tshuab.Lub helical flights ntawm cov ntsia hlau thawb cov khoom mus rau pem hauv ntej, thaum lub tshav kub generated los ntawm lub tshuab melts cov khoom thiab hloov mus rau hauv lub viscous xeev.

Lub tshuab extrusion ntsia hlau yog tsim los nrog ntau ntu uas ua haujlwm tshwj xeeb.Qhov chaw pub mis, nyob rau ntawm qhov pib ntawm cov ntsia hlau, yog lub luag haujlwm rau rub cov khoom thiab compressing nws.Lub cheeb tsam compression ua raws li, qhov twg cov khoom yog compressed thiab rhuab los ntawm kev sib txhuam thiab lub tshav kub generated los ntawm lub tshuab.

Lub melting cheeb tsam tuaj tom ntej, qhov twg cov khoom yog tag nrho melted thiab tov.Qhov seem ntawm cov ntsia hlau no feem ntau yog tsim los nrog lub kaum sab xis sib sib zog nqus los ua kom cov shearing kev txiav txim thiab txhawb kom muaj txiaj ntsig zoo thiab sib xyaw ntawm cov khoom.Thaum kawg, metering cheeb tsam tswj tus nqi ntws thiab siab ntawm cov khoom raws li nws raug thawb mus rau qhov tuag.

Lub tshuab extrusion ntsia hlau yog dav siv nyob rau hauv ntau yam lag luam, nrog rau cov yas, roj hmab, thiab kev ua zaub mov.Hauv kev lag luam plastics, cov ntsia hlau feem ntau yog siv los extrude yas pellets lossis granules rau hauv cov duab uas xav tau, xws li cov kav dej, profiles, lossis cov ntawv txheeb.Hauv kev lag luam roj hmab, cov ntsia hlau yog ua haujlwm los ua cov roj hmab sib txuas rau hauv ntau yam khoom, xws li cov ntsaws ruaj ruaj, gaskets, lossis cov log tsheb.Hauv kev lag luam khoom noj, cov ntsia hlau yog siv los extrude cov khoom noj khoom haus, xws li khob noom cookie lossis pasta.

Kev saib xyuas kom zoo thiab kev saib xyuas ntawm lub tshuab extrusion ntsia hlau yog qhov tseem ceeb los xyuas kom meej nws lub neej ntev thiab kev ua haujlwm.Kev tu thiab tshuaj xyuas tsis tu ncua pab tshem tawm cov khoom seem lossis cov kab mob uas tuaj yeem cuam tshuam cov txheej txheem extrusion.Tsis tas li ntawd, kev kuaj xyuas ib ntus rau kev hnav lossis kev puas tsuaj yog tsim nyog, thiab txhua yam hnav lossis puas tsuaj yuav tsum tau hloov tam sim ntawd.

Hauv kev xaus, lub tshuab extrusion ntsia hlau yog ib qho tseem ceeb hauv cov txheej txheem extrusion, lub luag haujlwm rau kev xa tawm, melting, thiab shaping cov khoom ua tiav.Kev nkag siab txog nws cov qauv, cov qauv kev ua haujlwm, thiab cov ntawv thov yog qhov tseem ceeb rau kev ua kom tau zoo thiab zoo extrusion.Los ntawm kev muab kev saib xyuas thiab kev saib xyuas kom zoo, cov tuam ntxhab tuaj yeem ua kom lub neej ntev thiab kev ua haujlwm zoo ntawm lub tshuab extrusion ntsia hlau.
