PA66 Polyamide Txoj Hlub Hlub Rau Thermal Break Strips | Zoo Tshaj Plaws GF25

PA66 polyamide, uas feem ntau hu ua nylon 66, yog ib hom polymer siv los ntawm neeg tsim thiab muaj zog tshaj plaws, muaj kev ceev siab zoo, tiv thaiv tau txiag txim rau cov khoom siv kim, thiab tsis huv. Lub material no tsim los ntawm kev sib sau ua ke ntawm adipic acid thiab hexamethylenediamine, tsim tau ib qhov chaw sib piv rau crystalline uas pab ntxiv zog thiab nyob dai. Cov yam ntxwv feem ntau muaj tensile strength ntawm 80–90 MPa, elongation at break ntawm 10–50%, thiab melting point ntawm 260°C, thiab heat deflection temperature uas nyob tawm li 70°C mus rau 100°C thaum muaj nqaij. Vim tias nws muaj kev xav kom nqus nqaij, nws xav tau kom nqus nqaij ua ntej nyob tawm li 80–100°C rau 2–4 teev ua vor ua ntej siv injection molding lossis extrusion, thiab lub teeb pom kev ua haujlwm yuav tsum nyob tawm li 270–290°C kom paub meej tias nws yooj yooj sib luag thiab crystallization zoo. PA66 polyamide feem ntau siv rau kev siv tshwj xeej xws li cov khoom siv rau rooj zaum (xws li cov fan blades, fuel lines), cov khoom sib cuag rau hluav taws xob, thiab cov sib ntxiv rau tej kab ntsug, vim nws muaj coefficient friction tsuas, kev tiv thaiv hluav taws xob zoo, thiab kev txaus siab rau kev sib tham nrog oils thiab hydrocarbons. Nws tuaj yeem kho dua los ntxiv yam ntxwv xws li stiffness thiab kev tiv thaiv kub los ntawm siv cov khoom ntxiv xws li glass fibers lossis minerals, thaum cov additives pab ntxiv kev nyob dai rau sab saum toj lossis kev tiv thaiv dej ntsuag. Cov nqe lus txog dej num muaj feem nrog nws tus kheej thaw thiab kev pab cuam ntxiv rau kev lag luam, tab sis kev daws teeb meem nqaij yog qhov tseem ceeb kom ntxiv kev nyob dai nyob hauv qhov chaw muaj nqaij ntau. Txhua yam, PA66 polyamide nyuaj siab hauv kev tsim kho, nws muaj kev siv ntau thiab kev txaus siab rau kev txhim kho cov standard kev ua haujlwm tseem ceeb nyob hauv ntau qhov chaw sib pauv, pab kom muaj kev nyob zoo thiab kev lag lag nyob rau hauv ntau yam khoom thiab hauv ntau cheeb tsam.
