1. Khoom npaj npaj
TPU Pellets Xaiv: Xaiv TPU Pellets nrog lub hardness tsim nyog (xws li muaj kev nyuaj siab (MFON), thiab kev ua haujlwm hnyav ntxiv, elasticity, thiab tshuaj lom neeg cov khoom yuav tsum tau ua.
Kom qhuav: TPU yog hygroscopic, yog li nws yuav tsum tau ua ntej - qhuav ua ntej extrusion tshem ya raws. Ya dej noo tuaj yeem ua rau npuas, qhov tsis xws luag, thiab txo cov khoom siv txo hauv cov khoom lag luam. Kev ziab khaub ncaws feem ntau nqa tawm ntawm qhov kub ntawm 80 - 100℃rau 3 - 6 teev.
2. Extrusion Txheej Txheem
Ib yam nkaus
Barrel: lub thoob ntawm Extruder yog rhuab hauv ntau qhov chaw mus rau maj mam yaj lub tpu pellets. Qhov ntsuas kub profile yog ua tib zoo teeb tsa kom muaj tseeb melting yam tsis muaj ntau dua - cua sov tuaj yeem ua rau muaj kev mob siab. Piv txwv li, qhov chaw pub mov kub tej zaum yuav nyob ib ncig ntawm 160 - 180 degree, thaj chaw me me, tab sis cov nqi no tuaj yeem sib txawv nyob ntawm TPU qib.
Ntsia hlau: Cov ntsia hlau tig nyob rau hauv lub thoob, conveying, compressing, thiab melting lub TPU Pellets. Txawv ntsia hlau tsim qauv (piv txwv li, ib leeg - ntsia hlau lossis ntxaib - ntsia hlau sib xyaw) tuaj yeem cuam tshuam nrog kev sib xyaw, thiab cov txheej txheem tso zis ntawm cov txheej txheem Extrusion. Ntxaib - cov ntsia hlau EXTRUDERS feem ntau muab kev sib xyaw zoo dua thiab ntau yam tsis zoo melting, tshwj xeeb tshaj yog rau cov qauv sib txawv.
Melting thiab sib xyaw: raws li TPU pellets txav mus los ntawm lub thoob, lawv tau yaj los ntawm kev sib xyaw ua ke los ntawm lub thoob thiab shear generated los ntawm lub ntsia hlau tig. Lub Molten TPU yog kom meej sib xyaw kom ntseeg tau cov homogeneous yaj.
Tuag tsim thiab kev sau: lub TPU yog yuam kom tuag, uas yog txiav txim rau tus ntoo khaub lig - cov duab ntawm cov khoom extruded. Tuag tuaj yeem kho tau los ua cov qauv sib txawv, xws li puag ncig rau cov hlab, duab plaub, lossis tiaj tus qauv thiab cov yeeb yaj kiab. Tom qab dhau mus dhau ntawm kev tuag, extruded tpu yog txias thiab solunified, feem ntau yog los ntawm kev hla dej da dej lossis siv cua txias.
3. Ncej - Kev Ua
Kev ntsuas tshuaj thiab sizing: rau qee cov khoom lag luam, kev ntsuas thiab cov haujlwm sib luag yog qhov yuav tsum tau ua kom ntseeg tau qhov ntev. Qhov no tuaj yeem siv cov tshuaj calibration, lub tshuab nqus hluav taws xob, lossis lwm yam sitizing kom tswj tau lub taub sab nraud, tuab, lossis lwm yam tseem ceeb ntawm cov khoom lag luam.
Txiav lossis winding: nyob ntawm daim ntawv thov, tus extruded TPU khoom yog siv rau hauv cov ntev (rau profiles, thiab lwm yam) lossis qhov txhab rau cov ntawv txheeb (rau cov ntawv qhia thiab cov yeeb yaj kiab).
Hauv cov ntsiab lus, qhov extrusion ntawm TPU yog cov ntsiab lus tsim khoom lag luam kev tshawb fawb thiab cov khoom lag luam zoo rau cov khoom lag luam thiab cov duab.
