Nylon (polyamide, PA) yog ib hom yas engineering uas muaj cov khoom siv kho tshuab thiab ua haujlwm zoo heev, ntawm cov PA6 thiab PA66 yog cov polyamide ntau hom.

Txawm li cas los xij, nws muaj kev txwv hauv kev tiv taus kub siab, tsis ruaj khov xim, thiab yooj yim nqus dej noo thiab hydrolysis.

Piv txwv li, tsab xov xwm no tshawb nrhiav seb yuav ua li cas thiaj txhim kho nws txoj kev tiv thaiv kev laus. Cov kev tshawb fawb cuam tshuam tau qhia tias kev ua tau zoo ntawm PA6 tuaj yeem txhim kho tau zoo los ntawm kev ntxiv cov tshuaj antioxidants thiab lwm yam khoom ntxiv. Tom qab kev sim tshuaj UV ntev thiab kev sim thermal stability, cov kev sib xyaw ua ke hauv qab no tau muab kev tiv thaiv zoo rau cov khoom siv kho tshuab thiab xim ntawm nylon:

①Cov tshuaj tiv thaiv kab mob 1098 + Cov tshuaj tiv thaiv kab mob 626

②Cov tshuaj tiv thaiv kab mob 245 + Cov tshuaj tiv thaiv kab mob 626

③Cov tshuaj tiv thaiv kab mob 1098 + Cov tshuaj tiv thaiv kab mob 168

Yuav kom lub neej ua haujlwm ntev dua ntawm PA, nws feem ntau yuav tsum ntxiv qee yam khoom ntxiv. Piv txwv li, ntxiv HALS los txhim kho lub teeb ruaj khov,LS770yog ib qho ntawm cov kev xaiv ua tau nrog kev cuam tshuam tsawg kawg nkaus rau cov khoom siv kho tshuab. Lub caij no, peb lub tuam txhab muab cov nylon stabilizer ntau yam hu uaLS438, uas txhim kho cov txheej txheem yaj ntawm polyamides, txhim kho lub sijhawm ntev kub thiab photo-stability, thiab txhim kho xim ceev.

Yuav kom ua kom dawb dua thiab npog qhov daj, TiO2, ultramarine xiav, cov neeg sawv cev ci ntsa iab, thiab lwm yam kuj tau ntxiv rau Polyamide.Tshuaj Pleev Xim Kho Qhov Muag KSNmuab los ntawm peb lub tuam txhab yog qhov kev xaiv zoo thiab tiv taus kub siab.

Tsis tas li ntawd,carbodiimide antihydrolysis tus neeg sawv cevtuaj yeem ntxiv los txhim kho nws cov kev ua haujlwm tiv thaiv hydrolysis thiab txuas ntxiv nws lub sijhawm oxidation induction los ntawm kev sib koom tes nrog lwm cov khoom ntxiv.

Cov lus qhia saum toj no tsis yog cov lus qhia txog kev siv tshuab, thiab kev ua tau zoo tiag tiag yuav tsum tau txiav txim siab los ntawm kev siv tus neeg siv.
