Iindaba - Izisombululo zeSi-TPV 2250 zezixhobo ze-EVA Foam eziNgcono kakhulu, ezihlala ixesha elide, nezisebenzayo

Izisombululo ze-Si-TPV zokuphucula intuthuzelo, ukuqina, kunye nokusebenza kakuhle kwemveliso kwizixhobo ze-foam ze-EVA

Imingeni yoKulahlekelwa yiFoam Rebound kunye nokuQina kweZihlangu ze-EVA

Abavelisi bezihlangu abaninzi bajongene nomceli mngeni wexesha elide:Ukulahleka kwe-EVA foam rebound ukuya kuthi ga kwi-10%emva kokugcinwa okanye ukusetyenziswa ixesha elide. Oku kuncipha kokuqina kuchaphazela intuthuzelo esecaleni, kunciphisa ukuqina kwezihlangu ze-EVA, kwaye kukhokelela kwizikhalazo eziphezulu zabathengi kunye namazinga okubuya.

YemveliI-EVA + SEBSiinkqubo zihlala zihlupheka ngenxa yezi zinto zilandelayo:

• ukuxinana okunganelanga kwe-crosslink,

• ukuphumla kwe-molecular chain,

• Ukungahambelani kwebanga le-SEBS.

Ezi ngxaki zinegalelo ekuwohlokeni kokusebenza, ukungazinzi kobukhulu, kunye nokubuyela umva okungaguqukiyo.

Imingeni nge-EVA Foam kunye neZisombululo eziQinisekisiweyo

Izisombululo zobugcisa zokuphucula uzinzo lwe-EVA Foam Rebound
1. Ukuphucula Ukwenziwa Kweefomyula
1.1 Ukuphucula Uxinano lweCrosslink
Yongeza i-DCP nge-10–20% kwaye wongeze i-0.1–0.2 phr TAIC ukuze uqinise ulwakhiwo lwenethiwekhi kwaye uzinzise ukusebenza kwefoam yexesha elide.
1.2 Khetha iiGrade ze-SEBS eziHlaziyiweyo eziphezulu
Sebenzisa i-SEBS eneempawu ezinamandla zokulwa nokushwabana ukugcina ukuthembeka kwe-molecular chain. Yidibanise ne-SEBS enobunzima obuphezulu ukuphucula amandla okutsalwa kunye nokumelana nokuguguleka.
1.3 Ukusetyenziswa okunengqiqo kokongeza
Ziphephe izinto zokufaka iplastiki ezinobunzima obuphantsi beemolekyuli.
Yongeza i-1–2 phr nano CaCO₃ okanye i-silica ukuqinisa ulusu lwe-foam.
Lawula umlinganiselo we-foam phakathi kwe-1.8–2.2 ukuze ufumane ukufana okungcono kweembobo.

2. Ukuphucula Inkqubo
• Yongeza ubushushu bokuphilisa nge-5–10°C (umz., 160°C → 165–170°C).
• Yandisa ixesha lokunyanga ngemizuzu emi-3-5 ukuqinisekisa ukuba i-crosslinking iyasebenza ngokupheleleyo.
• Faka ukuguga kwesibini kwi-80°C kangangeeyure ezi-2 ukuze ukhulule uxinzelelo lwangaphakathi kwaye womeleze ukuzinza kokubuyela umva kwexesha elide.
