Cov khoom no yog ib lub zog rau ntau yam CR, chlorosulfonated polyethylene roj hmab, CHR, polyacrylate roj hmab. Haum rau lub ntxhov siab uas siv los ntawm cov xim hlau oxide. Cov khoom no tuaj yeem txhim kho txoj kev ntxhov siab thiab txo cov deformation hauv compression, tshwj xeeb tshaj yog rau 54-1 (W) thiab dav GN CR thiab cable, nws yooj yim dispersed thiab tsis pom.

Nyob rau hauv lub system ntawm ETU neeg txhawb nqa rau neoprene, tom qab sib ntxiv ntawm TT, lub sij hawm coking tau ntev, lub ntawg crosslinking txo, tus fluidity raug kho, thiab lub cev thiab mechanical zog hloov raws li nram no:

1.Permanent compression deformation nce.

2.Huaj qis zog, lub zog hloov me me, kev loj hlob nce.

3.Qhov kev laus muaj zuj zus ntxiv, qhov kev loj hlob tseem ceeb heev thiab lub zog ua kom pom tseeb.

4.After hloov ETU nrog hva-2, qhov kev sib dhos ntawm qhov sib dhos thiab kev nplua ntawm cov nplaum yuav tsis zoo dua, kev laus kev ua tau zoo dua qub, thiab qhov kev hloov ntawm lub cev muaj qhov ua kom raug tsawg, uas yog ib nrab ntawm cov ETU nplaum.

5. Nyob rau hauv qhov system hva-2, thawj lub cev muaj zog tsawg dua li ntawm ETU. DM thiab TT siv tau los txhim kho coke hlawv thiab fluidity.TT yog superior rau DM (fluidity), tab sis cov cuab yeej laus ntawm DM yog superior TT.

6.Thaum DM raug siv los ua tus txhawb nqa ntawm hva-2, qhov kev sib dhos ntawm kev sib tshuam tsis sib haum lawm, qhov ruaj khov ntawm deformation tseem tsawg dua li ntawm hva-2 ib leeg, thiab qhov elongation thiab dua dua tau zoo dua.Thaum ntxiv ntawm TT, lub elongation tus nqi tau raug txo kom tsawg, vim tias TT tsis koom rau hauv qhov kev sib tshuam ntawm thawj theem pib thiab kev txhim kho kev ua tau zoo dua, tab sis nyob rau theem tom qab vulcanization, TT tau koom tes hauv kev sib tw thiab ntxiv cov kev sib dhos, DM.Yog li, hva-2 + TT muaj kev kawm zoo dua qub thiab kev pheej yig compression deformation dua li ETU ib leeg.
