Nylon Polyamide 66 (PA66) rau Thermal Break Strips | POLYWELL

Nylon polyamide 66, uas tshwm sim nyob rau hauv PA66, yog ib qhov siv zoo heev thiab txheej txheem thermoplastic uas muaj qhuj lus txaus siab ntau rau nws qhuj lus mekanik zoo, kev nyob ruaj khov ntawm kub, thiab kev cuam tshuam los ntawm cheeb. Nws tsim los ntawm adipic acid thiab hexamethylenediamine, tsim tau ib hom polymer uas muaj crystalline ib leeg thiab muaj melting point nyob rau 260°C thiab glass transition temperature nyob rau 50°C. Qhuj lus tseem ceeb muaj zog tshaj plaws ntawm 80–90 MPa, kev cuam tshuam zoo, thiab coefficients friction tsuas me ntsis, ua rau nws zoo tshaj plaws rau kev siv hauv tsev neeg yav tsaus, electronics, thiab tej kab mob. Vaj voos no tuaj yeem tsoj kub txog 120°C thiab muaj heat deflection temperature ntawm 70–100°C nyob rau 1.82 MPa, tab sis nws muaj kev nyob ruaj khov rau dej thiab tuaj yeem dhau dej, uas tuaj yeem muaj kev pheej xwm rau daim duab thiab qhuj lus mekanik yog tias tsis xav kom meej. Qhov kev tsim kho yog li injection molding thiab extrusion yuav tsum tau kub txog 270–290°C thiab thawv ua ntej nyob rau 80–100°C kom tiv thaiv hydrolysis. PA66 feem ntau raug hloov kho los ntawm cov roj teeb xim nkhaus kom ntxim dua thiab nyob ruaj khov rau kub, lossis nrog cov khoom xa khoom rau UV stability thiab flame retardancy. Cov kev siv feem ntau muaj gears, bearings, thiab electrical insulators, uas nws kev nyob ruaj, kev tiv thaiv hluv, thiab kev cuam tshuam rau huab thiab solvents yog qhov tseem ceeb. Cov xwm txheej tshaj tawm ntawm sustainability muaj recyclability thiab kev pib tsim cov precursor zoo los ntawm bio, kom reduce qhov impact rau hauv environment. Txhua yam, nylon polyamide 66 yog ib qho vaj voos siv ntau thiab muaj kev sib thooj zoo, uas sib xyeej ntau yam kev siv thiab txheej txheem, txhawj xeeb rau kev tsws yees thiab kev nyob ruaj khov hauv kev tsim kho vaj voos.
