Nkhani - Mayankho a Si-TPV 2250 a Zipangizo Zofewa za EVA Zotonthoza Kwambiri, Zolimba, komanso Zogwira Ntchito

Mayankho a Si-TPV kuti awonjezere chitonthozo, kulimba, komanso magwiridwe antchito opangira zinthu zopangidwa ndi thovu la EVA

Mavuto Okhazikika a Kutayika ndi Kukhazikika kwa Nsapato za EVA

Opanga nsapato ambiri akukumana ndi vuto lalikulu kwa nthawi yayitali:Kutayika kwa thovu la EVA mpaka 10%mutasunga kapena kugwiritsa ntchito nthawi yayitali. Kuchepa kumeneku kwa kulimba mtima kumakhudza chitonthozo cha pakatikati pa nsapato, kumachepetsa kulimba kwa nsapato za EVA, ndipo kumabweretsa madandaulo ambiri kwa makasitomala ndi kuchuluka kwa kubweza.

ZachikhalidweEva + SEBSMa system nthawi zambiri amavutika ndi:

• Kusakwanira kwa kuchuluka kwa ma crosslink,

• kupumula kwa unyolo wa mamolekyulu,

• Kusagwirizana kwa SEBS grade.

Mavuto amenewa amachititsa kuti magwiridwe antchito awonongeke, kusakhazikika kwa mawonekedwe, komanso kuchira kosasinthasintha kwa rebound.

Mavuto ndi EVA Thovu ndi Mayankho Otsimikizika

Mayankho Aukadaulo Othandizira Kukhazikika kwa Foam ya EVA
1. Kukonza Mapangidwe
1.1 Kuonjezera Kuchuluka kwa Crosslink
Wonjezerani DCP ndi 10–20% ndikuwonjezera 0.1–0.2 phr TAIC kuti mulimbikitse kapangidwe ka netiweki ndikukhazikitsa magwiridwe antchito a thovu kwa nthawi yayitali.
1.2 Sankhani Magiredi a SEBS Okwera Kwambiri
Gwiritsani ntchito SEBS yokhala ndi mphamvu zotsutsana ndi kufupika kuti musunge umphumphu wa unyolo wa mamolekyu. Phatikizani ndi SEBS yolimba kwambiri kuti muwongolere mphamvu yokoka komanso kukana kukalamba.
1.3 Kugwiritsa Ntchito Zowonjezera Mwanzeru
Pewani zinthu zopaka pulasitiki zokhala ndi mamolekyu ochepa.
Onjezani 1–2 phr nano CaCO₃ kapena silica kuti mulimbikitse chigoba cha thovu.
Onetsetsani kuti chiŵerengero cha thovu chili pakati pa 1.8–2.2 kuti mukhale ndi ma pore ofanana bwino.

2. Kukonza Njira
• Wonjezerani kutentha kwa kuzizira ndi 5–10°C (monga, 160°C → 165–170°C).
• Wonjezerani nthawi yothira ndi mphindi 3-5 kuti muwonetsetse kuti kulumikizana konse kuli bwino.
• Ikani ukalamba wachiwiri pa 80°C kwa maola awiri kuti muchotse kupsinjika kwamkati ndikuwonjezera kukhazikika kwa nthawi yayitali.

Si-TPV 2250-75A Chosinthira cha Thermoplastic Elastomer Chosawononga Zachilengedwe1

Chosinthira thovu la SI-TPV Soft-elastic EVA

Ukadaulo Watsopano mu Zipangizo za Foam za EVA - Sinthani Magwiridwe Anu ndi Si-TPV 2250 Series Soft-elastic EVA foam modifier

Si-TPV 2250 Series ya SILIKE ndi yothandiza kwambiri.chosinthira cha elastomer cha thermoplastic chosavuta kuwononga chilengedwezomwe zimatanthauziranso ukadaulo wa thovu la mankhwala a EVA, kuonetsetsa kuti thovu limakhala lofanana komanso losasinthasintha. Mwa kupewa kusamuka kwa mankhwala ndikupereka chiŵerengero chosinthika cha thovu, Si-TPV imawonjezera magwiridwe antchito opangira, imachepetsa kugwiritsa ntchito mphamvu, komanso imapangitsa kuti thovu lonse lizigwira ntchito bwino.

Mndandanda wa Si-TPV 2250Zowonjezera za thovu la EVA zomwe siziwononga chilengedweZimathandiza kupanga thovu la EVA lochepa, lolimba kwambiri komanso losatha kusweka ndi kutsetsereka, lochepa kutentha, lokhala ndi mtundu wofanana, komanso lopangidwa bwino kwambiri. Kusavuta kwake kukonza komanso kugwiritsa ntchito ndalama moyenera kumapangitsa kuti likhale njira yabwino kwambiri m'malo mwa njira zachikhalidwe zopangira thovu lofunika kwambiri.

Mndandanda wa Si-TPV 2250 wa SILIKEelastomer yochokera ku silicone yopangidwa ndi thermoplastic yolimbaimapereka yankho lothandiza pazinthu zopangira thovu la EVA, zomwe zimapangitsa kuti nsapato, zida zamasewera, zida zamankhwala, ndi ma phukusi azikhale zotetezeka, komanso zotetezeka.

Kafukufuku Woyerekeza: Zotsatira za Si-TPV 2250-75A vs. Polyolefin Elastomer Additives mu EVA Foam (40A Hardness)

1. Kubwerera Mpira Woponya

KungowonjezeraThovu la 20% Si-TPV 2250-75A kupita ku EVA (kulimba kwa 40A) limathandizira kulimba kwa reboundkuchokera pa 49% mpaka 51% — kupeza zotsatira zofanana ndi 20% OBC, pomwe kumapereka maubwino abwino okonza ndi kupititsa patsogolo kukhazikika.

2. Kutentha Kuchepa

Kuonjezera 20%Thovu la Si-TPV 2250-75A kupita ku EVA (kulimba kwa 40A) limachepetsa kutentha pang'onokuyambira 2.1% mpaka 0.75% yokha — zomwe zimapereka kukhazikika kwabwino kwambiri kuposa ma polyolefin elastomers ena.

3. Kuchuluka kwa DIN Variation

Kuphatikiza20% Si-TPV 2250-75A mu thovu la EVA (kulimba kwa 40A) kumachepetsa kuvala kwa DINkuyambira 872 mm³ mpaka 424 mm³ — imapereka kukana kwa kukanda kofanana ndi kuwonjezera 5% ya mankhwala oletsa kukanda NM-2.

4. Kusintha kwa Kupsinjika

Mu thovu la EVA (kulimba kwa 40A), kuwonjezera kwaSi-TPV 2250-75A imathandiza kuchepetsa kusintha kwa kupsinjika, kulimbitsa mawonekedwe ake komanso kukhalitsa kwa nthawi yayitali.

5. Kusiyana kwa Mitundu

Pambuyo poyika Si-TPV 2250-75A, thovu la EVA limawonetsa mtundu wofiira kwambiri komanso mtengo wa A wokwera, zomwe zikusonyezakukongola kwa mtundu ndi mawonekedwe okongola.

Kodi mwakonzeka kukweza magwiridwe antchito a zinthu za thovu za EVA?

Mukufuna ma thovu a EVA okhala ndi rebound yokhalitsa, osasunthika bwino, komanso osamalira chilengedwe? Si-TPV 2250 Series ya SILIKE imapereka yankho lothandiza kuti zinthu zikhale bwino, zolimba, komanso zogwira mtima popanga zinthu.

Lumikizanani ndi SILIKE kuti mupezeMayankho a thovu a EVA a Si-TPV 2250 Series opepuka kwambiri, otanuka, komanso ochezeka ndi chilengedwezomwe zimawonjezera nsapato zamasewera, nsapato wamba, ma insoles azachipatala, ndi zina zomwe zimafuna thovu lapamwamba la EVA lokhala ndi rebound yapamwamba, chitonthozo, kukana kuvala, komanso kukhazikika.
