ETPU Foaming Materials muaj qee qhov tsis zoo

Lo rau ntawm: PECOAT | nyob rau lub Cuaj Hli 7, 2023

tsoos EVA Cov ntaub ntawv ua npuas dej muaj qhov tsis zoo, thiab tom qab hnav rau lub sijhawm, cov khoom yuav tawg thiab tawg. Kev hloov kho cov khoom siv nrog POE, roj hmab, thiab lwm yam ntaub ntawv tuaj yeem kho thiab txhim kho cov khoom siv, tab sis kev txhim kho yog txwv. Nyob rau tib lub sij hawm, muaj teeb meem xws li siab shrinkage thiab nyuaj rau molding. Cov txheej txheem tsim khoom siv tshuaj foaming, uas tsis yog tsuas yog ua rau muaj kuab paug rau ib puag ncig tab sis kuj ua rau muaj kev phom sij rau tib neeg lub cev.

ETPU Cov ntaub ntawv ua npuas ncauj muaj cov khoom siv hluav taws xob muaj ultra lub teeb, ultra-siab resilisence, thiab siv cov pa roj carbon dioxide raws li cov txheej txheem npaj ua npuas dej. Lawv yog tsim los ntawm ntshiab lub cev foaming txoj kev, uas yog ntsuab, environmentally friendly, tsis muaj kuab paug, thiab tsis muaj tshuaj residues. Txawm li cas los xij, tam sim no ETPU foaming cov ntaub ntawv tseem muaj cov nram qab no shortcomings.

1.Tam sim no, lub foaming particle npaj tshuab tsis paub tab txaus, thiab kev npaj ntawm ETPU cov hais feem ntau yog nyob ntawm kev paub. Cov TPU foaming txheej txheem thiab nws cov txheej txheem tsis to taub zoo, thiab tsuas yog ob peb lub tuam txhab tuaj yeem tsim lawv hauv ntau qhov ntau, uas yog deb ntawm kev ua lag luam xav tau. ETPU cov ntaub ntawv foaming.

2.Qhov TPU foaming hais tsis raug rau tom qab kev kho mob, cov foaming hais yuav maj mam shrink kom txog thaum lawv ua compact. Tam sim no, ob txoj kev tsim tau tau npaj tseg: txoj kev ua kom txias ceev ceev thiab txoj kev tuav cov cua txias.

3.Qhov ceev cov cuab yeej depressurizes, lub fuller thiab brighter lub ETPU foamingmaterialsparticles yuav, thiab siab dua qhov rebound elasticity. Vim tsis muaj peev xwm ntawm cov cuab yeej uas twb muaj lawm kom tau raws li qhov siab depressurization tus nqi xav tau rau TPU foaming, kev txhim kho ntxiv ntawm cov khoom siv foaming yog xav tau.

4. Hauv TPU Cov txheej txheem cua sov ua kom sov, cov khoom siv hluav taws xob thermocouple feem ntau yog siv rau cov cua sov, uas ua rau cov cua sov tsis sib xws, ua rau qhov tsis sib xws ntawm qhov ntau thiab tsawg. ETPU cov khoom. Qhov npaj foamed hais muaj qhov ntom ntom muaj qhov ntau dua, ntxhib saum npoo, loj loj, thiab tsis muaj mob daj thiab hydrolysis ntawm cov lus.

5.Thaum tus txheej txheem ntawm kev tsim cov midsole hauv ETPU khau, lub ntsiab kub-kub chav vuam molding txoj kev yuav ua rau tsis tiav vuam thiab tsis meej nto qauv, tshwj xeeb tshaj yog rau polyester-raws li TPU, uas tej zaum yuav undergo hydrolysis thiab tig daj nyob rau hauv high-kub dej vapor.

6.Tam sim no, feem ntau ntawm kev npaj ETPU foaming cov ntaub ntawv hais yog cov ntaub ntawv ib leeg-xim. Muaj ob txoj hauv kev kom ua tiav cov xim ETPU: Direct dyeing ntawm TPU ua npuas ncauj nrog pigments los yog qhia dyed polyols los npaj cov xim TPU ua ntej foaming.

Direct dyeing ntawm TPU ua npuas ncauj nrog pigments nthuav tawm qhov teeb meem loj thiab nyuaj, uas yog pigment migration ua rau cov xim txawv ntawm cov khoom kawg. Qhov no yog qhov tshwj xeeb tshaj yog nyob rau hauv high-temperature water vapor molding, qhov twg cov txheej txheem cua sov ntxiv txhawb kev tsiv teb tsaws ntawm me me molecule dyes thiab exacerbates xim variations.

Qhia dyed polyols los npaj cov xim TPU Ua ntej foaming tso cai rau cov dyes kom tawg mus rau hauv daim ntawv microscopic hauv cov saw hlau polymer. Nrog kev pab los ntawm coupling agents zoo li silane, cov xim molecules yog grafted mus rau lub polymer chains, tiv thaiv kev tsiv teb tsaws ntawm cov xim molecules nyob rau hauv lub TPU nyob rau hauv high-kub dej vapor. Txawm li cas los xij, cov txheej txheem no suav nrog cov khoom siv polymerization thiab muaj cov txheej txheem nyuaj dua.
