Anti-kev lausSolution ntawmPolyamide (Nylon, PA)
Nylon (polyamide, PA) yog ib qho yas engineering nrog cov khoom siv kho tshuab thiab kev ua haujlwm zoo, ntawm cov PA6 thiab PA66 yog ntau hom polyamide.
Txawm li cas los xij, nws muaj kev txwv hauv qhov kub thiab txias tsis kam, tsis muaj xim ruaj khov, thiab nws yooj yim rau kev nqus dej thiab hydrolysis.
Noj PA6 ua piv txwv, kab lus no tshawb fawb txog kev txhim kho nws txoj kev laus. Cov kev tshawb fawb ntsig txog tau pom tias qhov kev ua tau zoo ntawm PA6 tuaj yeem txhim kho tau zoo los ntawm kev ntxiv qhov tsim nyogantioxidantsthiab lwm yam additives. Tom qab lub sij hawm ntev UV raug kuaj thiab ntsuas thermal stability, cov nram qab no ua ke tau muab kev tiv thaiv zoo rau cov khoom siv thiab xim ntawm nylon:
①Antioxidant 1098+ Antioxidant 626
②Antioxidant 245+Antioxidant 626
③Antioxidant 1098+Antioxidant 168
Txhawm rau txuas ntxiv kev pab cuam lub neej ntawm PA, feem ntau yuav tsum tau ntxiv qee yam ntxiv. Piv txwv li, ntxiv HALS los txhim kho lub teeb ruaj khov,SIB 770yog ib qho ntawm cov kev xaiv ua tau nrog qhov cuam tshuam tsawg kawg ntawm cov khoom siv kho tshuab. Meanwhile, peb lub tuam txhab muab ib tug multifunctional nylon stabilizer hu uaSIB 438, qho txhim kho yaj ua ntawm polyamides, txhim kho cov cua sov mus sij hawm ntev thiab yees duab ruaj khov, thiab txhim kho xim ceev.
Txhawm rau txhim kho qhov dawb thiab npog yellowing, TiO2, ultramarine xiav, optical brightening agents, thiab lwm yam kuj tau ntxiv rau Polyamide. Cov Optical Brightener KSNmuab los ntawm peb lub tuam txhab yog kev xaiv zoo thiab kub-resistant.
Ntxiv rau,carbodiimide tiv thaiv-hydrolysis tus neeg sawv cev tuaj 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 ib qho kev taw qhia, thiab kev ua tau zoo tiag tiag yuav tsum tau txiav txim siab los ntawm cov neeg siv kev xyaum.
