Kev tsim cov txheej txheem ntawm TPU zaj duab xis rau cov ntaub
Feb 24, 2025
1. Raw khoom npaj
Ua ntej, xaiv cov khoom zoo TPU, uas nws cov ntsuas kev ua tau zoo xws li hardness, elasticity, thiab huab cua tsis kam yuav tsum ua kom tau raws li cov kev xav tau ntawm cov ntaub lamination. Cov ntaub sib txawv siv sib txawv rau cov yam ntxwv sib txawv ntawm TPU. Piv txwv li, TPU siv nyob rau hauv sportswear yuav tsum muaj ob qho tib si elasticity thiab zoo hnav tsis kam. Qhuav cov ntaub ntawv raw kom tshem tawm cov dej noo, vim tias cov dej noo yuav ua rau TPU hydrolysis thaum ua thiab txo cov yeeb yaj kiab zoo. Feem ntau, lub tshuab nqus tsev ziab yog siv, uas yog qhuav rau ob peb teev ntawm qhov kub thiab txias degree.
2. Extrusion plasticization
TPU qhuav pellets yog pub rau hauv extruder. Lub extruder siv lub siab rau cov khoom thiab thawb nws mus rau pem hauv ntej los ntawm tig lub hau. Thaum lub sijhawm txheej txheem no, cov cuab yeej cua sov ntawm lub thoob maj mam ua kom sov cov TPU pellets mus rau lub xeev molten, thiab qhov kub thiab txias feem ntau tswj tau ntawm 180-230 degree . Kev tswj qhov kub thiab txias yog qhov tseem ceeb. Yog tias qhov kub thiab txias qis dhau lawm, cov plasticization tsis txaus, thiab cov yeeb yaj kiab yuav muaj teeb meem xws li cov pob tawv tawv thiab tawv tawv; Yog tias qhov kub thiab txias dhau lawm, TPU tuaj yeem decompose thiab cuam tshuam rau kev ua haujlwm.
3. Moulding
Lub molten TPU yog extruded los ntawm cov tuag los ua ib daim ntawv zaj duab xis ntawm tej thickness thiab dav. Tus tsim ntawm qhov tuag txiav txim siab qhov sib txawv ntawm qhov sib txawv thiab qhov tseeb ntawm cov yeeb yaj kiab. Cov hom kev tuag feem ntau suav nrog cov hanger tuag, uas tuaj yeem ua kom muaj kev sib faib ntawm cov ntaub ntawv thiab tsim cov yeeb yaj kiab nrog cov tuab tuab. Nyob rau tib lub sijhawm, qhov kawg thickness ntawm zaj duab xis yog tswj los ntawm kev kho cov extrusion ceev thiab rub ceev. Qhov ob yuav tsum tau ua kom raug sib raug zoo kom ntseeg tau tias cov yeeb yaj kiab thickness kam rau ua nyob rau hauv qhov kev teev tseg.
4. Txias thiab ua kom zoo
Cov yeeb yaj kiab extruded los ntawm lub taub hau tuag muaj qhov kub thiab txias thiab yuav tsum tau txias thiab zoo li tus. Txoj kev ua kom txias yog siv lub tshuab ua kom txias. Cov zaj duab xis yog nyob ze rau ntawm qhov chaw ntawm lub tshuab cua txias, thiab lub coolant circulating nyob rau hauv cov menyuam yuav tshem tawm cov cua sov, yog li ntawd cov zaj duab xis yog sai txias thiab solidified. Cov cua txias ceev yuav cuam tshuam rau cov qauv siv lead ua thiab kev ua haujlwm ntawm zaj duab xis. Kev nrawm dhau los yog qeeb dhau yuav ua rau muaj teeb meem xws li kev ntxhov siab sab hauv thiab warping hauv zaj duab xis.
5. Tom qab ua tiav
Cov yeeb yaj kiab tsim yog dov thiab hlais rau hauv qhov dav thiab ntev raws li cov lus qhia tshwj xeeb uas yuav tsum tau ua rau cov ntaub ntau lawm. Cov yeeb yaj kiab tuaj yeem raug kho saum npoo, xws li kev kho mob corona, txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau corona Thaum kawg, tom qab kev tshuaj xyuas nruj, cov khoom tsim nyog tuaj yeem ntim thiab xa tawm.
