Nylon 66 Polymer rau Thermal Break Strips | PA66 GF25 Granules & Solutions

Nyloj 66 tshuaj polymer yog ib qhov thermoplastic uas muaj crystalline, muaj zog, nyob ntev, thiab txaus siab rau kev siv kawg nkaus ntawm qhov polyamide. Kev tsim tshuaj polymer yog ua los ntawm kev sib txig sib to los tsim cov kab uas muaj amide uas pab tso hydrogen, tiam sis ntxiv rau crystallinity (feem ntau yog 35-45%). Qhov crystallinity no pab tso zog hluav taws xob ntawm 85 MPa thiab flexural modulus ntawm 3 GPa, ua rau nws zoo rau kev siv rau cov khoom siv xwmfab xwm txhab thiab cov khoom siv hluav taws xob. Nws muaj qhov cim tshav kub ntawm 260°C thiab Vicat softening point nyob rau sab 240°C, uas pab nws tuaj tau zoo thaum muaj kev npog tshav kub. Qhov tshav kub tsis loj (pob 0.24 W/m·K) ua rau nws zoo rau kev tiv thaiv tshav kub, xws li rau cov thermal break strips rau tsev lag, uas ntxiv kev ruaj nqah los ntawm kev tshem tshav kub. Tab sis Nyloj 66 polymer feem ntau yuav dab tsi rau dej, uas tuaj yeem tsim kev plasticize rau khoom, muaj zog tsawg dua thiab ntxiv zog impact; vim li no, kev tiv thaiv lossis sau nrog feem ntau yuav tsum tau ua thaum nyob rau qhov chaw muaj dej. Cov kev tsim khoom xws li injection molding yuav tsum muaj kev coov txog tebchaws kub kom tsis txhob phom sij, nrog tebchaws kub ntawm melt nyob rau 270-290°C uas yog zoo tshaj plaws rau kev flow thiab crystallization. Cov khoom ntxiv xws li heat stabilizers lossis lubricants tuaj yeem pab ntxiv kev ua haujlwm rau kev siv tshwj xeej, xws li rau electrical insulators uas dielectric strength yog tseem ceeb. Cov ntsiab lus tshwj xeej rau environment yog tias nws tsis tuaj yeem yav tom qab, tab sis kev recycling los ntawm kev grinding thiab reprocessing pab kom tsis pub khoom pov tseg. Thim rau lwm yam nylon, Nyloj 66 muaj kev tiv thaiv tshav kub thiab kev ua haujlwm zoo dua Nylon 6, tab sis nws tuaj yeem muaj nqi ntau dua. Cov kev siv feem ntau ntawm industrial gears mus rau sports equipment, siv nws muaj kev tiv thaiv fatigue thiab friction coefficients tsis ntau. Cov kev pab ntxeem tshiab hauv copolymerization thiab nanotechnology xav pab ntxiv properties, kom nws muaj txoj haujlwm rau sustainable thiab high-performance designs hauv yoj ywg.
