Xov Xwm - Si-TPV 2250 Cov Kev Daws Teeb Meem rau Cov Khoom Siv EVA Ua Npuas Ncauj Uas Xis Nyob, Ruaj Khoov, thiab Siv Tau Zoo

Cov kev daws teeb meem Si-TPV los txhim kho kev nplij siab, kev ruaj khov, thiab kev ua haujlwm zoo ntawm cov khoom siv ua npuas ncauj EVA

Kev Poob Rov Qab Los Ntawm EVA Ua Npuas Ncauj & Kev Sib Tw Ua Kom Khau Ruaj Khov

Ntau tus neeg tsim khau ntsib teeb meem ntev:EVA ua npuas ncauj rov qab poob txog li 10%tom qab khaws cia lossis siv ntev. Qhov kev poob qis ntawm qhov kev ywj pheej no cuam tshuam rau qhov xis nyob ntawm lub hauv paus, txo qhov ruaj khov ntawm EVA khau, thiab ua rau cov neeg siv khoom tsis txaus siab thiab cov nqi rov qab ntau dua.

Ib txwm muajEVA + SEBScov kab ke feem ntau raug kev txom nyem los ntawm:

• qhov sib txuas tsis txaus,

• kev so ntawm cov saw hlau molecular,

• Kev tsis sib haum xeeb ntawm qib SEBS.

Cov teeb meem no ua rau muaj kev puas tsuaj ntawm kev ua haujlwm, kev tsis ruaj khov ntawm qhov loj me, thiab kev rov qab zoo li qub tsis sib xws.

Cov Teeb Meem Nrog EVA Ua Npuas Ncauj Thiab Cov Kev Daws Teeb Meem Uas Tau Pom Zoo

Kev daws teeb meem kev siv tshuab los txhim kho EVA Foam Rebound Stability
1. Kev Txhim Kho Cov Qauv
1.1 Txhim Kho Qhov Ceev ntawm Crosslink
Nce DCP los ntawm 10–20% thiab ntxiv 0.1–0.2 phr TAIC los txhawb cov qauv network thiab ua kom ruaj khov rau kev ua haujlwm ua npuas dej mus sij hawm ntev.
1.2 Xaiv Cov Qib SEBS Uas Rov Qab Zoo
Siv SEBS uas muaj cov khoom tiv thaiv kev ntsws kom tswj tau qhov ruaj khov ntawm cov saw hlau molecular. Siv ua ke nrog SEBS uas muaj qhov nyuaj dua los txhim kho lub zog tensile thiab kev tiv thaiv kev hnav.
1.3 Kev Siv Cov Khoom Ntxiv Uas Muaj Peev Xwm
Tsis txhob siv cov plasticizers uas muaj molecular weight tsawg.
Ntxiv 1–2 phr nano CaCO₃ lossis silica kom ua kom lub pob txha ua npuas ncauj ruaj khov.
Tswj qhov sib piv ntawm 1.8–2.2 rau qhov sib npaug zoo dua.

2. Kev Txhim Kho Cov Txheej Txheem
• Ua kom qhov kub ntawm kev kho kom zoo dua 5–10°C (piv txwv li, 160°C → 165–170°C).
• Ncua lub sijhawm kho kom ntev li 3–5 feeb kom paub tseeb tias muaj kev sib txuas ua ke tag nrho.
• Siv kev laus zaum ob ntawm 80°C rau 2 teev kom tso tawm kev ntxhov siab sab hauv thiab txhim kho kev ruaj khov rov qab mus sij hawm ntev.
