PI (polyimide) hmoov, pas nrig, ntawv, cnc tsim cov khoom lag luam

Thermosetting polyamides yog paub rau thermal stability, cov tshuaj zoo, thiab cov yam ntxwv zoo nkauj / daj xim. Polyamities compounded nrog graphite lossis khob fiber ntau reights muaj qhov ua tau zoo ntawm 340 mpa (49,000 moduli ntawm 21,000 mpa (3,000,000 PSI). Thermoses polymer matrix polyamides pom kev ua tau zoo heev thiab lub zog qis tensile lub zog. Cov khoom no yog tswj xyuas thaum siv sijhawm ntev mus txog 232 ° C (450 ° F) thiab rau kev mus ncig ua si, kom siab li 704 ° F). [11] Moulded polyimimide seem thiab laminates muaj cov kub ua kom zoo heev. Kev ua haujlwm ib txwm txias rau cov ntu thiab laminates ntau yam los ntawm cryogenic rau cov tshaj li 260 ° C (500 ° F). Polyamides kuj tseem muaj kev tiv thaiv kom cov nplaim hluavteeb rau cov nplaim taws thiab tsis tas yuav tsum tau sib xyaw nrog nplaim taws retardants. Feem ntau nqa cov ul ul ntsuas ntawm VTM-0. Polyimaus laminates muaj lub zog flexural zog ib nrab ntawm 249 ° C (480 ° F) ntawm 400 teev.

Raug polyimide seem tsis cuam tshuam los ntawm cov kuab tshuaj uas nquag siv thiab roj, suav nrog cov roj hydrocarbons, esters, dej cawv thiab ferns. Lawv kuj tawm tsam cov kua qaub tsis muaj zog tab sis tsis pom zoo rau kev siv nyob rau hauv ib puag ncig uas muaj cov alkalis lossis inorganic acids. Qee cov polyamides, xws li CP1 thiab Corin XLS, yog cov kuab tshuaj-solu-soluble thiab nthuav tawm cov teeb pom kev kub siab. Cov khoom siv solubility qiv rau lawv rau ntawm cov tshuaj tsuag thiab tsis tshua muaj tshuaj kho cov ntawv thov.
