Izindaba - Izixazululo ze-Si-TPV 2250 zezinto ze-EVA Foam ezinenduduzo ephezulu, ezihlala isikhathi eside, nezisebenza kahle

Izixazululo ze-Si-TPV zokuthuthukisa induduzo, ukuqina, kanye nokusebenza kahle kokukhiqiza ezintweni ze-foam ze-EVA

Izinselele Zokuqina Kokulahlekelwa Nokuqina Kwezicathulo ze-EVA Foam Rebound

Abakhiqizi abaningi bezicathulo babhekene nenselele yesikhathi eside:Ukulahlekelwa yi-EVA foam rebound kufika ku-10%ngemva kokugcinwa noma ukusetshenziswa isikhathi eside. Lokhu kwehla kokuqina kuthinta induduzo ephakathi kwezinyawo, kunciphisa ukuqina kwezicathulo ze-EVA, futhi kuholela ezikhalweni zamakhasimende eziphezulu kanye namazinga okubuya.

YendabukoI-EVA + SEBSizinhlelo zivame ukuhlushwa yi:

• ukuminyana okunganele kwe-crosslink,

• ukuphumula kwe-molecule chain,

• Ukungahambisani kwebanga le-SEBS.

Lezi zinkinga zinegalelo ekuwohlokeni kokusebenza, ukungazinzi kobukhulu, kanye nokululama okungalingani kokubuyela emuva.

Izinselele nge-EVA Foam kanye nezixazululo eziqinisekisiwe

Izixazululo Zobuchwepheshe Zokuthuthukisa Ukuzinza Kokubuyela Emuva Kwe-Foam ye-EVA
1. Ukuthuthukisa Ukwakheka
1.1 Thuthukisa Ubuningi be-Crosslink
Khulisa i-DCP ngo-10–20% bese wengeza i-TAIC engu-0.1–0.2 phr ukuze uqinise isakhiwo senethiwekhi futhi uzinzise ukusebenza kwe-foam yesikhathi eside.
1.2 Khetha Amabanga E-High-Rebound SEBS
Sebenzisa i-SEBS enezakhiwo eziqinile zokulwa nokushwabana ukuze ulondoloze ubuqotho be-molecular chain. Hlanganisa ne-SEBS enobunzima obuphezulu ukuze uthuthukise amandla okuthambekela kanye nokumelana nokuguguleka.
1.3 Ukusetshenziswa Okunengqondo Kokwengeza
Gwema ama-plasticizers anesisindo esincane sama-molecule.
Engeza i-1–2 phr nano CaCO₃ noma i-silica ukuze uqinise uhlaka lwe-foam.
Lawula isilinganiso se-foam esiphakathi kuka-1.8–2.2 ukuze uthole ukufana okungcono kwe-pore.

2. Ukuthuthukisa Inqubo
• Khulisa izinga lokushisa lokupholisa ngo-5–10°C (isb., 160°C → 165–170°C).
• Nweba isikhathi sokulungisa ngemizuzu emi-3-5 ukuqinisekisa ukuxhumanisa okuphelele.
• Faka ukuguga kwesibili ku-80°C amahora ama-2 ukuze ukhulule ukucindezeleka kwangaphakathi futhi uthuthukise ukuzinza kokubuyela emuva kwesikhathi eside.

I-Si-TPV 2250-75A I-Thermoplastic Elastomer Modifier1 Enobungani Nemvelo

Isilungisi sefoam se-EVA esithambile nesinwebekayo se-SI-TPV

Ubuchwepheshe Obusha Kwezinto Ze-EVA Foam – Thuthukisa Ukusebenza Nge-Si-TPV 2250 Series Soft-elastic EVA foam modifier

Uchungechunge lwe-Si-TPV 2250 lwe-SILIKE luyi-i-thermoplastic elastomer modifier enobungani nemveloechaza kabusha ubuchwepheshe bokwenza igwebu ngamakhemikhali e-EVA, iqinisekisa ukufana okuphezulu kanye nokuvumelana. Ngokuvimbela ukufuduka kwamakhemikhali kanye nokunikeza isilinganiso sokwenza igwebu esilungisekayo, i-Si-TPV ithuthukisa ukusebenza kahle kokukhiqiza, inciphisa ukusetshenziswa kwamandla, futhi ithuthukisa ukusebenza kwegwebu iyonke.

Uchungechunge lwe-Si-TPV 2250Izithasiselo ze-foam ze-EVA ezinobungani nemveloivumela ukukhiqizwa kwama-foam e-EVA aphansi, aqinile kakhulu anokumelana nokuguguleka okuhle kakhulu, ukuncipha kokushisa, umbala ofanayo, kanye nomkhiqizo oqediwe kakhulu. Ukulula kwawo ukucutshungulwa kanye nokusebenza kahle kwezindleko kuyenza ibe yindlela engcono kakhulu kunezindlela zendabuko zokufaka amagwebu angaphezulu kokubalulekile.

Uchungechunge lwe-Si-TPV 2250 luka-SILIKEi-elastomer esekelwe ku-silicone eguquguqukayo e-thermoplasticinikeza ikhambi elisebenzayo lezinto zokwenza i-EVA ibe yisivikelo, ukuqina, kanye nokusimama kuzo zonke izicathulo, imishini yezemidlalo, amadivayisi ezokwelapha kanye nezinhlelo zokupakisha.

Ucwaningo Lokuqhathanisa: Imiphumela Yezithasiselo ze-Si-TPV 2250-75A vs. Polyolefin Elastomer ku-EVA Foam (Ukuqina kwe-40A)

1. Ukubuyela emuva kwebhola eliwisiwe

Ukwengeza njeI-foam engu-20% Si-TPV 2250-75A kuya ku-EVA (ubulukhuni be-40A) ithuthukisa ukuqina kokubuyela emuvakusuka ku-49% kuya ku-51% — ukuthola imiphumela ecishe ifane ne-20% OBC, ngenkathi kunikezwa izinzuzo zokucubungula ezithuthukisiwe kanye nokusimama.
