TPE yog ib qho chaw zoo thiab tsis muaj kuab lom, muaj qhov siab ntawm rubber, yog li dav siv rau cov khoom ua si sab nraum zoov, xws li tsheb kauj vab, Rally, cov ntiv taw kev sib tw, kev sib tw khiav qav, tsom iav thiab lwm yam. Cov neeg mob tau txais kev txhawj xeeb yog txhawj txog TPE cov khoom siv tiv taus hluav taws xob (hluav taws xob) lossis teeb meem tiv thaiv kev laus.

1. kev laus yog kev tsis ntseeg ntuj

Kev laus yog ib qho txheej txheem rau kev xwm txheej. Qhov tseem ceeb tshaj plaws nyob ib puag ncig peb yog tus txheej txheem ntawm lub neej txij thaum yug, kev loj hlob thiab kev laus, uas yog qhov kev laus tshaj plaws. Yog li, txawm nws yog yas, elastomer los yog hlau thiab lwm yam

cov ntaub ntawv, yog inevitably maj "laus"!

2. qhov kev ua tiav ntawm cov thermoplastic elastomer khoom laus

Los ntawm cov kev ua tau zoo qis, mus rau ib qho twg, tuaj yeem soj ntsuam los ntawm lub ntsej muag me me

saib:

Lost lus, uas yog qhov phenomenon ntawm cov laus khoom nto;

Yellowing, uas txhais tau hais tias cov nyiaj ntawm cov tshuaj hauv cov pob zeb tawg lossis hloov pigment;

Ploj, qhia cov xim uas tsis haum lossis poob

Cov nplaim ntawm cov khoom hmoov, los ua pov thawj tias cov polymer tau loj hnub nyoog

Mechanical zog ntawm cov khoom hloov, xws li nkig, yooj yim tawg, nkig, puas ntsoog, hais tias lub puab

polymer molecules tau tawg.

3. Vim li cas cov khoom siv thermoplastic elastomer yuav muaj hnub nyoog

a. Macro tsom xam

Vim hais tias muaj kev sib tov ntawm tej yam tshwm sim xws li cua sov, dej, dej, lub teeb, tshuaj tua kab thiab tshuaj nruab nrab thaum lub sijhawm ntawm tus qauv polymer, cov tshuaj muaj pes tsawg leeg thiab tus qauv yuav hloov pauv thiab lub cev nqaij daim tawv yuav hloov raws li phem, xws li nyuaj plaub hau, nplaum, brittle, heev, tsis muaj zog, cov kev pauv thiab qhov tshwm sim yog hu ua kev laus.

bmicroscopic tsom xam

Polymer nyob rau hauv qhov kev txiav txim ntawm lub tshav kub los yog lub teeb yuav zoo siab lub xeev lub cev, thaum lub zog siab txaus, molecular saw yuav tawg ua dawb radicals, dawb radicals tau tsim ib cov saw fab hauv lub polymer, ntxiv mus ua kom degradation, kuj yuav Ua Ntej Khaub Lig.

Yog tias muaj oxygen lossis ozone nyob rau hauv ib puag ncig, nws kuj ua rau kom muaj cov tshuaj oxidation, ua cov hydroperoxides (ROOHs), thiab txuas ntxiv rau carbonyl pawg.

Yog hais tias tus polymer nyob rau hauv muaj cov residual catalyst hlau ions, los yog ua, siv cov hlau ions xws li tooj liab, hlau, manganese, cobalt, thiab lwm yam., Yuav accelerate oxidative degradation ntawm qhov tshuaj tiv thaiv polymer.
