Super kuwala zotanuka Environment-wochezeka EVA thobvu zinthu kukonzekera

fotokozani:

EVA thovu zinthu ndi mtundu wa zinthu thovu kuti amapangidwa EVA (ethylene-vinyl acetate copolymer) ndi otsika kachulukidwe polyethylene (LDPE) monga zopangira ndi zina zowonjezera.Ili ndi kusinthasintha kwabwino, kusinthasintha kwa mphira, kuwonetsetsa bwino komanso gloss pamwamba, kukhazikika kwamankhwala abwino, anti-kukalamba, ndi kukana kwa ozoni, kosakhala poizoni.

Anthu ambiri amaganiza kuti EVA thovu zakuthupi ndi kuphatikiza wangwiro chipolopolo cholimba ndi zofewa chipolopolo, Komabe, ntchito EVA thovu zipangizo ndi malire pamlingo wakuti chifukwa cha ukalamba kukana, flexure kukana, elasticity, ndi abrasion kukana.Kukwera kwa ETPU m'zaka zaposachedwa komanso kuyerekeza kwa zitsanzo kumapangitsanso nsapato za EVA thovu kukhala ndi kuuma pang'ono, kubwezeredwa kwapamwamba, kutsika kwapang'onopang'ono, ndi zinthu zina zatsopano ndi zinthu zopangidwa ndi thovu la EVA zomwe zimaperekedwa pamsika pano zimakonzedwa ndi njira yothira thovu. ndipo amagwiritsidwa ntchito makamaka pazinthu monga nsapato, matiresi pansi, ndi zina zotero zomwe zimagwirizana mwachindunji ndi matupi aumunthu.Komabe, zinthu zotulutsa thovu za EVA zokonzedwa ndi njirayo ndipo njirayo imakhala ndi chitetezo chambiri komanso zovuta zaumoyo, ndipo makamaka, zinthu zovulaza (makamaka formamide) zimasiyanitsidwa mosalekeza ndi mkati mwazogulitsa kwa nthawi yayitali.

Mavuto enieni ndi awa: choyamba, kutentha kwa kutentha kwa mankhwala otulutsa thovu kumafunika kukhala pamwamba pa kutentha komwe EVA yatsala pang'ono kusungunuka ndi njira ya EVA yotulutsa thovu, ndipo kutentha kwapang'onopang'ono kwa mankhwala otulutsa thovu ndi kwakukulu. ndipo ndondomeko yowonongeka imaphatikizapo kulinganiza kwa mankhwala, kotero kuti mankhwala opangira thovu amakhalabe ochuluka muzitsulo zakuthupi pambuyo pomaliza thovu, miyeso yoyenga EVA yotsika kutentha m'malo osasungunuka ndikuwonjezera kuwonjezera kwa mndandanda wothandizira. zinthu monga cross-linking agent, stearic acid, cross-linking initiator, chemical foaming agent agent decomposition catalyst, plasticizer ndi zina zotero zimatengedwa makamaka m'makampani pofuna kuchepetsa mphamvu ya otsalira a thovu pakuchita thovu. zinthu, koma miyeso mwachindunji chifukwa chachikulu kuchuluka kwa micromolecular wothandiza wothandizila zosavuta kusamuka mu chomaliza mankhwala, ndi wothandizira mosalekeza amasamukira pamwamba pa mankhwala kuchokera mkati pamodzi ndi ntchito nthawi yaitali, kotero kuti matenda pakhungu kapena Kuipitsa kwina komwe kumalumikizidwa ndi mankhwalawa kumayambitsidwa;Kachiwiri, mukupanga thovu lamankhwala, kuwonongeka kwa chinthu chomwe chikuwomba mankhwala chomwe chimawonetsa kutulutsa thovu ndi kuphatikizika kwamankhwala komwe kumatsimikizira kusungunuka kwa rheology kumapitilira nthawi imodzi, ndipo kutentha koyenera kuwonongeka kwa mankhwala omwe amawomba sikotentha koyenera kwambiri. kusungunula rheology kwa ma cell nucleation ndi kukula.Kuphatikiza apo, mankhwala otulutsa thovu ndi kuphatikizika kwamankhwala ndi njira zosunthika zomwe zimachitidwa mosalekeza ndi nthawi, ndipo kudalira kwa kutentha kumakhala kolimba kwambiri.Njira yokonzekera thovu la EVA pogwiritsa ntchito thovu la mankhwala liyenera kuganizira za kuphatikizika ndi kuchita thovu nthawi imodzi kuti kukhathamiritsa kwa ma cell kumakhala kovuta.

Pofuna kuthetsa mavuto omwe ali pamwambawa, opanga zinthu akhala akufufuza ndi kuphunzira mwakhama.kuphatikiza kwa EVA thovu zinthu ndi zipangizo zina elastomer wakhala otentha kafukufuku pakati opanga nsapato.

Ubwino waukulu

01

Sinthani kukhuthala kwa zida za thovu la EVA

Poyerekeza ndi ufa wa talcum kapena anti-abrasion agent, Si-TPV ili ndi elasticity yabwino.
02

Sinthani machulukitsidwe amtundu wa zida za thovu la EVA

Magulu ena pa Si-TPV atha kuyanjana ndi ma chromophores a utoto, kukulitsa kuchulukitsitsa kwamitundu.
03

Chepetsani kutentha kwazinthu za thovu la EVA

Kukhazikika kwa Si-TPV kumathandizira kumasula kupsinjika kwamkati kwa zinthu za thovu la EVA.
04

Sinthani kukana kwa anti-abrasion kwa zida za thovu za EVA

Si-TPV imatha kutenga nawo gawo pamachitidwe olumikizirana, omwe amawonjezera kachulukidwe wolumikizana.
05

Heterogeneous nucleation

Si-TPV imamwazikana mofanana muzinthu za thovu za EVA, zomwe zingathandize cell nucleation.
06

Chepetsani kupindika kwa zinthu za thovu za EVA

Si-TPV ili ndi magwiridwe antchito abwino kwambiri komanso otsika kutentha, ndipo nthawi imodzi imatha kusintha mawonekedwe apamwamba komanso otsika kutentha kwazinthu zolimba kwambiri za EVA thovu.

Kukhalitsa Kukhazikika

Ukadaulo wapamwamba kwambiri wopanda zosungunulira, wopanda plasticizer, wopanda mafuta ofewetsa, komanso wopanda fungo.
Kuteteza chilengedwe ndi kubwezeretsedwanso.
Amapezeka m'mapangidwe ogwirizana ndi malamulo.
