PA66 Pellets rau qhov chaw ntxoog kub zoo tshaj plaws | PA66 GF25

PA66 pellets yog daim ntawv rau PA66 polymer uas tsim los rau kev siv hauv tsev lag luam uas tsim nyog rau kev pab cuam ntau thiab yooj yim. Cov daim no muaj qhov loj thiab duab tiag tiag, pab rau kev sib txuas zoo hauv qhov chaw sau ua kom yooj yim thiab sib ruv zoo hauv kev tsim kho lossis kev tshuab tshuaj. Qhov tshwm sim ntawm cov khoom muaj zog siab (zog tshem tau txog 90 MPa), zoo tiv thaiv kev puav tseg, thiab qhov kub tshem txog li 260°C, thiab qhov kub tiv thaiv yog 70–100°C nyob ntawm qhov load. Thwj ci ntsiab lus kho kom sai 270–290°C thiab thwj ci ntsiab lus tshuab kom sai 60–100°C kom tau qhov crystallinity xwb thiab kom saib xyaw cov teeb meem xws li khaum lossis ceev. Vim PA66 muaj kev nyiam dej, cov daim yuav tsum siv dej ntxias nyob ntawm 80–100°C nrog 2–4 teev kom tiv thaiv cov teeb meem xws li dej ntxias lossis kev sib txuas tsawg dua thaum tshuab. Cov kev siv khoom feem ntau rau tshwj tsim hlwb (xws li huab cua tanks, fasteners), cov khoom sib chig, thiab cov khoom siv hauv tse, qhov kev tuaj yeem ntxiv ntau lossis ntxiv cov khoom sib txuas xws li fiberglass tuaj yeem pab ntau yam kev siv. Cov khoom muaj kev tiv thaiv zoo tshaum neeg, dej tshuaj, thiab khoom kem, yog li tsim nyog rau qhov chaw nyuaj, tab sis yuav tsum tau ntxig cov UV stabilizers rau kev siv hauv av. Kev nyab xeeb yog qhov tseem ceeb, PA66 pellets tuaj yeem rov siv dua thiab feem ntau siv hauv kev rov qab kom tsawg dej. Txhua yam, cov daim no muaj kev pab zoo rau tsev lag luam, pab kev siv yooj yim thiab muaj kev nyab xeeb, kev nyab xeeb thiab kev kub sov, kom txheej tau kev xav tau ntawm cov khoom siv plastic zoo tagnrho rau ntau yam kev siv.
