1.Kev ntim khoom noj thiab dej haus
2. Cov ntaub ntawv ua yeeb yaj kiab
3. Fibers thiab textiles
4.Engineering yas

Lub uniqueness ntawm PEF nyob rau hauv qhov tseeb hais tias tus qauv txiav txim siab kev ua tau zoo, kev ua tau zoo adapts rau cov kev xav tau, thiab cov kev xav tau ua raws li cov kev xav tau zoo: Cov qauv furan nplhaib endows nws nrog cov khoom thaiv thiab thermal stability deb tshaj cov PET. Cov khoom siv rov ua dua tshiab ua raws li cov cai ntawm ib puag ncig, sib haum nrog cov khoom siv uas twb muaj lawm, thiab txo qis kev lag luam. Nws yog tom ntej no - cov khoom siv tseem ceeb hauv kev ntim khoom thiab textiles.

Kev kho tsis tiav ntawm cov nplaum yog ib qho teeb meem tshwm sim hauv cov txheej txheem lamination qhuav ntawm PEF cov khoom noj sib xyaw ua ke. Qhov teeb meem tseem ceeb yog tias tus ntoo khaub lig- sib txuas cov tshuaj tiv thaiv ntawm tus neeg sawv cev tseem ceeb ntawm cov nplaum thiab tus neeg sawv cev kho tsis tau ua tiav, ua rau muaj ntau ntawm cov pab pawg tsis muaj zog ntxiv. Qhov no tsis yog tsuas yog cuam tshuam ncaj qha rau cov khoom tseem ceeb xws li interlayer adhesion thiab media resistance, tab sis kuj ua rau cov zaub mov tiv thaiv kev nyab xeeb vim kev tsiv teb tsaws ntawm cov khoom tsis sib haum xeeb, thiab tib lub sijhawm cuam tshuam rau kev tuav ntawm PEF cov khoom muaj teeb meem siab.

Kev siv ntau dhau ntawm cov kuab tshuaj-dawb polyurethane nplaum yuav ua rau muaj kev cuam tshuam ncaj qha rau cov khoom thaiv siab thiab pob tshab ntawm PEF cov yeeb yaj kiab los ntawm peb qhov loj: cov qauv ntawm cov nplaum nplaum nws tus kheej, lub xeev kev sib txuas, thiab txoj kev sib kis ntawm lub teeb. Ntxiv mus, tus nqi tseem ceeb ntawm PEF yog qhov tseeb hauv nws cov khoom muaj kev cuam tshuam siab.

Lub crosslinking ceev ntawm polyurethane adhesives yog lub ntsiab yam ntxwv parameter uas tswj lub boiling tsis kam thiab freezing tsis kam ntawm PEF composite daim nyias nyias. Qhov yuav tsum tau muaj rau crosslinking ceev ntawm ob yog nyob rau hauv ib tug inverse complementary kev sib raug zoo: lub boiling kuj yuav tsum tau ib tug high crosslinking ceev, cia siab rau ib tug ntom crosslinking network los tiv thaiv kev puas tsuaj los ntawm kub kub, siab kub thiab high humidity; lub freezing kuj yuav tsum tau ib tug nruab nrab mus rau tsawg crosslinking ceev, cia siab rau qhov tsawg crosslinking ntawm saj zawg zog molecular chains kom tsis txhob muaj tsawg - kub brittleness thiab internal stress cracking. Ntxiv mus, qhov crosslinking ntom yuav tsum phim lub rigidity thiab thermal shrinkage yam ntxwv ntawm PEF membrane; txwv tsis pub, nws yuav exacerbate kev ua haujlwm tsis ua haujlwm.
