Polyethylene (PE) cov kav dej tau siv dav hauv ntau qhov kev lag luam vim lawv cov kav ntev, yoog raws, thiab tiv thaiv corrosion. Cov txheej txheem ntawm kev tsim cov kav dej no suav nrog cov txheej txheem hu ua extrusion. Wb delve rau hauv cov mechanics ntawm PE yeeb nkab extrusion.
Txheej txheem Extrusion
1 、 Kev npaj khoom:
Pelletization: Polyethylene resin feem ntau yog xa hauv daim ntawv me me pellets.
Kev ziab: Cov pellets qhuav kom tshem tawm cov dej noo uas tuaj yeem degrade cov khoom kawg.
2, Extrusion:
Cua sov: Cov pellets qhuav yog pub rau hauv ib qho extruder, qhov chaw uas lawv tau rhuab mus rau lawv qhov melting point.
Melting thiab Mixing: Ib tug ntsia hlau nyob rau hauv lub extruder sib tov cov yas molten thiab thawb nws mus rau pem hauv ntej.
Shaping: Lub molten yas yog yuam los ntawm ib tug tuag nrog ib tug tshwj xeeb cov duab, nyob rau hauv cov ntaub ntawv no, ib tug hollow profile uas phim cov yeeb nkab qhov ntev.
3, Txias thiab Sizing:
Txias: Cov yeeb nkab extruded dhau los ntawm lub dab da dej txias los yog mus rau lub txaj txias kom khov cov yas.
Sizing: Raws li cov yeeb nkab txias, nws dhau los ntawm cov cuab yeej sizing uas ua kom nws ua tau raws li qhov ntev.
4. Txiav:
Ntev: Thaum cov yeeb nkab tau txias thiab khov kho, nws raug txiav mus rau qhov ntev uas xav tau.
5, Kev tshuaj xyuas thiab ntim:
Kev Tswj Xyuas Zoo: Cov kav dej tau txais ntau yam kev kuaj xyuas kom ntseeg tau tias lawv ua tau raws li cov qauv xav tau.
Ntim: Cov kav dej tau muab ntim thiab ntim rau kev thauj mus los.
Cov ntsiab lus tseem ceeb ntawm cov kab Extrusion:
Hopper: Pub cov polyethylene pellets rau hauv extruder.
Extruder: Melts cov yas thiab yuam nws los ntawm qhov tuag.
Tuag: Tsim cov yas molten rau hauv cov yeeb nkab uas xav tau.
Cooling system: Cools thiab solidifies cov yeeb nkab extruded.
Sizing ntaus ntawv: Xyuas kom cov yeeb nkab ua tau raws li qhov loj me.
Cutter: Txiav cov yeeb nkab mus rau qhov ntev uas xav tau.
Qhov zoo ntawm PE yeeb nkab Extrusion:
Versatility: PE kav dej tuaj yeem tsim muaj ntau qhov ntau thiab tsawg thiab muaj cov khoom sib txawv.
Efficiency: Cov txheej txheem extrusion yog qhov ua tau zoo thiab tuaj yeem tsim cov yeeb nkab ntau hauv cov txheej txheem txuas ntxiv.
Tus nqi zoo: PE yog cov khoom siv pheej yig, ua rau cov txheej txheem kev lag luam.
Precision: Cov cuab yeej extrusion niaj hnub tso cai rau kev tswj xyuas meej ntawm qhov ntev thiab cov khoom ntawm cov yeeb nkab tiav.
Kev siv ntawm PE Pipes:
Kev faib dej: Cov kav dej PE feem ntau siv rau kev faib dej haus vim lawv tsis kam tiv thaiv corrosion thiab tshuaj lom neeg.
Gas Distribution: Lawv kuj yog siv rau kev faib cov pa roj.
Cov kav dej PE yog siv rau cov kav dej, suav nrog cov kav dej.
Irrigation: PE kav yog siv nyob rau hauv kev ua liaj ua teb daim ntaub ntawv rau irrigation.
Hauv kev xaus, PE yeeb nkab extrusion txheej txheem yog ib txoj kev ua tau zoo thiab muaj ntau yam los ua cov kav dej zoo rau ntau yam kev siv. Los ntawm kev nkag siab txog cov hauv paus ntsiab lus ntawm cov txheej txheem no, koj tuaj yeem txaus siab rau engineering thiab thev naus laus zis koom nrog hauv kev tsim cov khoom tseem ceeb no.
