ETPU Zida Zotulutsa thovu Zili ndi Zolakwika Zina
Traditional EVA zinthu za thovu zimakhala zosalimba bwino, ndipo zitavala kwa nthawi ndithu, zinthuzo zimagwa ndi kuphulika. Kusintha zinthu ndi POE, mphira, ndi zida zina zimatha kusintha ndikuwongolera zinthu, koma kuwongolera kuli kochepa. Pa nthawi yomweyo, pali nkhani monga shrinkage mkulu ndi zovuta akamaumba. Kupangaku kumagwiritsa ntchito thovu lamankhwala, lomwe silimangowononga chilengedwe komanso limatulutsa zotsalira zovulaza m'thupi la munthu.
ETPU tinthu tating'onoting'ono tating'onoting'ono timakhala ndi kachulukidwe kopitilira muyeso, kulimba kwambiri, komanso kugwiritsa ntchito mpweya woipa kwambiri ngati wotulutsa thovu pokonzekera. Amapangidwa ndi njira yeniyeni yotulutsa thovu, yomwe ndi yobiriwira, yosakonda zachilengedwe, yopanda kuipitsa, komanso yopanda zotsalira za mankhwala. Komabe, panopa ETPU zotulutsa thovu akadali ndi zofooka zotsatirazi.
1.Currently, ndi thobvu tinthu kukonzekera luso si okhwima mokwanira, ndi kukonzekera ETPU particles amadalira makamaka pa zochitika. The TPU kutulutsa thovu ndi makina ake sizikumveka bwino, ndipo makampani ochepa okha ndi omwe angapange zinthu zambiri, zomwe sizikukwaniritsa zofunikira za msika. ETPU thovu zipangizo.
2.Ngati TPU tinthu tating'onoting'ono tating'onoting'ono tating'onoting'ono tating'onoting'ono tating'onoting'ono tating'onoting'ono tating'onoting'ono tating'onoting'ono tating'onoting'ono tomwe timapanga thovu. Pakalipano, njira ziwiri zopangira zaperekedwa: njira yopangira kuzizira kofulumira komanso njira yolipirira mpweya.
3.The mofulumira zida depressurizes, wodzaza ndi owala ETPU foamingmaterialsparticles adzakhala, ndi apamwamba rebound elasticity. Chifukwa cha kulephera kwa zida zomwe zilipo kuti zikwaniritse kuchuluka kwa depressurization komwe kumafunikira TPU kutulutsa thovu, kuwongolera kwina kwa zida zotulutsa thovu kumafunika.
4. Mu TPU Kutentha kwa thovu, ndodo zotenthetsera za thermocouple nthawi zambiri zimagwiritsidwa ntchito potenthetsera, zomwe zimapangitsa kuti tinthu ting'onoting'ono ting'onoting'ono ting'onoting'ono ting'onoting'ono ting'onoting'ono ting'onoting'ono ting'onoting'ono ting'ono ting'ono ting'ono ting'ono ting'ono ting'ono ting'ono ting'ono ting'ono ting'ono ting'ono ting'ono ting'ono. ETPU particles. The okonzeka thobvu particles ndi apamwamba kachulukidwe, akhakula pamwamba, kwambiri shrinkage, ndi osauka kukana chikasu ndi hydrolysis wa particles.
5.Panthawi yopangira midsole mkati ETPU nsapato, njira yowotcherera yotentha kwambiri ya nthunzi imatha kupangitsa kuti pakhale kuwotcherera kosakwanira komanso mawonekedwe osadziwika bwino apamtunda, makamaka potengera poliyesitala. TPU, yomwe imatha kukhala ndi hydrolysis ndikusintha chikasu pansi pa nthunzi wamadzi wotentha kwambiri.
6.Currently, ambiri okonzeka ETPU thovu zipangizo particles ndi amodzi-amitundu zipangizo. Pali njira ziwiri kukwaniritsa akuda ETPU: kuyanika mwachindunji kwa TPU thovu lokhala ndi inki kapena kuyambitsa ma polyols opaka utoto kuti apange utoto TPU pamaso thovu.
Direct utoto wa TPU thovu lokhala ndi ma pigment limapereka vuto lalikulu komanso lovutirapo, lomwe ndi kusamuka kwa pigment kumabweretsa kusiyanasiyana kwamitundu muzomaliza. Izi zimakhala zodziwika kwambiri pakuwotcha kwamadzi otentha kwambiri, komwe kutenthetsa kumapangitsanso kusuntha kwa utoto wa ma molekyulu ang'onoang'ono ndikuwonjezera kusiyanasiyana kwamitundu.
Kuyambitsa ma polyols opaka utoto kuti akonzekere utoto TPU pamaso thovu amalola utoto kumwazikana mu mawonekedwe microscopic mkati polima unyolo. Mothandizidwa ndi zinthu zophatikizira monga silane, mamolekyu a utoto amalumikizidwa pamaketani a polima, kuletsa kusamuka kwa mamolekyu a utoto mkati mwa utoto. TPU pansi pa kutentha kwakukulu kwa madzi. Komabe, njirayi imaphatikizapo polymerization yakuthupi ndipo imakhala yovuta kwambiri.
