Glass Filled Polyamide PA66 GF25 rau cov chaw tshuab kawv txoj kab uas tsim nyog

Polyamide siv txos rwb qhov muaj roj teeb yog daim ntawv rau qhov chaw thermoplastic composites uas muaj polyamide resins, xws li PA66 lossis PA6, uas tau raug tshuv los ntawm cov kab ntsuas roj teeb kom ua rau zoo dua nyob rau hniav taws, kev ruaj khov thiab kev txaus siab. Cov kab roj teeb, feem ntau yog 10–50% nyob rau hniav taws, tau sib thooj nrog thaum compounding, tsim cov duab ntawv uas muaj kev ntxoov ntxooj zoo dua (xws li 150–200 MPa rau PA66 GF25), flexural modulus (8–14 GPa), thiab saff deflection temperatures (200–270°C). Cov composite no muaj kev lag luam hloov siab thiab kev txaus siab zoo dua li polyamides tsis muaj, ua rau nws zoo rau cov khoom siv tshwj xeeb hauv tsev kawm yeej, hluav taws xob, thiab khoom siv hauv tse. Kev them nyiaj yog injection molding lossis extrusion, muaj kev daws tswj kev ceev (kev ntxuav taws ntawm 260–290°C rau PA66-based grades) thiab nraws kom tiv thaiv kab ntsuas roj teeb puav thiab kom meej meej. Qhov tshaib ntawm cov kab roj teeb roj teeb tau xav tau cov khoom siv tiv thaiv thiab duab ntawv tiv thaiv, thaum qhov tshaib ntawm polyamide tau xav tau pre-drying kom tiv thaiv kev phom sij. Cov kev siv yog hniav taws, insulators, thiab cov khoom siv tshwj xeeb, uas muaj kev sib piv ntawm ntau, kev ruaj khov, thiab kev tiv thaiv tsis pub cuam tshuam los yog tshaib. Cov ntaub ntawv kev nyab xeeb, xws li kev rooj sib cuam thiab kev siv cov roj tshaib tsis muaj halogen, sib phim nrog kev nyab xeeb hauv cheeb tsam. Cov polyamides siv roj teeb tau zoo heev, pab tau kev kho tshwj xeeb los ntawm kab ntsuas roj teeb, cov khoom siv tshwj xeeb, lossis cov khoom siv tshwj xeeb kom dhau rau kev xav tau tshwj xeeb, thiab nws muaj kev leej hnub zoo dua rau cov neeg siv hluav taws xob hauv tse, kom paub tseeb tias muaj kev pab ntau hauv qhov chaw thiab kev sib tw.
