Tsis ntev los no, thaum sawv daws booming kev txhim kho ntawm kev lag luam tshuaj lom neeg, PMDA), muaj qhov muaj zog tshaj tawm hauv kev lag luam, muaj kev kawm zoo, thiab tshawb xyuas cov zej zog.
Raws li ib qho tseem ceeb organic tshuaj raw tshuaj, pyromellitic dianhydride yuav zoo li unreadarkable thaum xub thawj siab ib muag, tab sis nws yeej muaj lub peev xwm tshwj xeeb. Los ntawm cov khoom lag luam tsim muaj ntau, ntau cov kev lag luam siv tshuaj nyeg hauv tsev muaj zog ua rau lawv cov dag zog ua kom nce qib thiab nthuav lawv cov kab ntau lawm. [Lub tuam txhab npe] Chinese] Tshuaj Co., Ltd. nyuam qhuav ua tiav qhov kev ua kom zoo thiab hloov kho cov txheej txheem ntau lawm rau Pyromellitic dianydride. Cov thev naus laus zis tshiab tau lees paub kev tswj hwm uas tau ua kom muaj kev tswj hwm cov ntsiab lus tseem ceeb xws li cov tshuaj tiv thaiv kub thiab siab. Qhov no tau nce cov khoom siv purity los ntawm ze li 3 feem pua cov ntsiab lus thiab txo cov ntsiab lus impurity. Nws tsis tsuas yog ua kom muaj kev ruaj ntseg ntawm cov khoom lag luam tom ntej tab sis kuj txhim kho ib lub sijhawm tsim nyog los ntawm ntau dua 20%, muab cov tuam txhab ua ntej kev sib tw ua lag luam ntau.
Hauv daim ntawv thov teb, Pyromellitic dianhydride ci ntsa iab txawm meej. Cov pab pawg tshawb fawb tau kawm tas li nws lub peev xwm hauv kev txhim kho cov ntaub ntawv zoo. Hais txog cov ntaub ntawv hluav taws xob, cov yeeb yaj kiab polyimide synthesized los ntawm kev siv hluav taws xob, muaj peev xwm ua tau zoo heev ntawm cov khoom siv insulating, tseem muaj peev xwm ua tau zoo ib yam li ntawm cov khoom siv insulating, Cov kev lag luam hluav taws xob ua haujlwm tau mus txog ib qho kev sib koom tes zoo nkauj nrog cov khoom lag luam polyimide hauv kev sib tw rau kev sib tw rau kev sib tw ntawm cov khoom sib txuas lus tom ntej.
Lub aerospace sector tseem tsis yog lagging qab. Ua tsaug rau qhov kev kub-kub thiab hluav taws xob-resistant yam khoom ntawm cov khoom siv hluav taws xob dianhyized tau siv los tsim cov khoom sib xyaw ntawm cov npoo ntawm cov npoo ntawm lub dav hlau ntawm lub dav hlau. Piv nrog tsoos hlau ib txwm, lawv txo qhov hnyav los ntawm ntau dua 30%, pab pawg tsheb ya mus deb thiab ntau dua. Ntxiv mus, thaum cov ntaub ntawv synthesized los ntawm cov tshuaj no tau koom rau hauv cov txheej txheem tiv thaiv sab nraud thiab qhov sib txawv ntawm cov ntaub ntawv tshwj xeeb, ua kom muaj cov ntaub ntawv ruaj khov sib kis rau cov chaw ua haujlwm nyuaj.
