Pyromellitic DianhydrideCAS2420-87-3: Ib tug "Nees Tsaus Ntuj" hauv Kev Tshawb Fawb Txog Cov Khoom Siv Tshuaj Tshiab Nyiam Kev Lag Luam

Tsis ntev los no, thaum muaj kev loj hlob ntawm kev lag luam tshuaj lom neeg, pyromellitic dianhydride (PMDA), ib qho tshuaj tseem ceeb, tau maj mam nkag mus rau hauv qhov chaw pom kev, txhaj tshuaj muaj zog rau hauv kev tsim kho tshiab ntawm ntau yam khoom siv siab thiab ua rau muaj kev tshawb nrhiav tshiab thoob plaws hauv kev lag luam, kev kawm, thiab cov zej zog tshawb fawb.

Ua ib yam khoom siv organic tseem ceeb, pyromellitic dianhydride tej zaum yuav zoo li tsis tseem ceeb thaum xub thawj siab, tab sis nws muaj peev xwm tshwj xeeb. Los ntawm sab kev tsim khoom, ntau lub tuam txhab tshuaj lom neeg hauv tsev tab tom ua kom lawv cov kev siv zog los txhim kho thiab nthuav lawv cov kab ntau lawm. [Lub Npe Tuam Txhab] Chemical Co., Ltd. nyuam qhuav ua tiav kev txhim kho thiab txhim kho cov txheej txheem ntau lawm rau pyromellitic dianhydride. Cov thev naus laus zis tshiab siv lub kaw lus tswj hwm ntse uas tswj hwm cov yam ntxwv tseem ceeb xws li qhov kub thiab siab ntawm cov tshuaj tiv thaiv. Qhov no tau ua rau cov khoom huv si ntau dua li 3 feem pua ​​thiab txo cov ntsiab lus tsis huv. Nws tsis tsuas yog ua kom muaj kev ruaj khov ntawm qhov zoo ntawm cov khoom tom qab tab sis kuj txhim kho kev ua haujlwm ntau lawm, nrog rau cov zis ib chav tsev nce ntau dua 20%, ua rau lub tuam txhab muaj txiaj ntsig zoo hauv kev lag luam sib tw heev.

Hauv daim teb thov, pyromellitic dianhydride ci ntsa iab dua. Cov pab pawg tshawb fawb yeej ib txwm tshawb nrhiav nws lub peev xwm hauv kev tsim cov khoom siv ua tau zoo. Hais txog cov khoom siv hluav taws xob, cov zaj duab xis polyimide uas tsim los ntawm nws muaj qhov tuab tsuas yog ib nrab ntawm cov khoom siv rwb thaiv tsev ib txwm muaj, tab sis nws tuaj yeem tiv taus cov hluav taws xob txog li ntau pua volts, muaj qhov ruaj khov dielectric tas mus li, thiab cov khoom siv cua sov zoo heev, muab cov kev daws teeb meem zoo tshaj plaws rau qhov teeb meem ntawm kev rwb thaiv tsev thiab ntim cov chips me me, precision hauv 5G thiab txawm tias yav tom ntej 6G cov khoom siv sib txuas lus. Ib lub tuam txhab thev naus laus zis hluav taws xob ua lag luam tau mus txog kev koom tes zoo nrog cov neeg muab khoom siv raw thiab tau ua tus thawj coj hauv kev sim cov khoom ntim chip uas muaj cov zaj duab xis polyimide tshiab, siv zog ua tus thawj coj hauv kev sib tw rau cov khoom siv thev naus laus zis sib txuas lus tiam tom ntej.

Lub chaw ua haujlwm aerospace kuj tsis poob qis. Ua tsaug rau cov khoom siv uas ua los ntawm pyromellitic dianhydride uas tiv taus kub thiab tiv taus hluav taws xob, cov yas engineering tseem ceeb siv los tsim cov khoom tiv thaiv sib dua ntawm ntug ntawm tis dav hlau. Piv nrog cov khoom siv hlau ib txwm muaj, lawv txo qhov hnyav ntau dua 30%, txo kev siv roj thiab pab cov tsheb aerospace ya mus deb dua thiab ruaj khov dua. Ntxiv mus, thaum cov khoom siv uas ua los ntawm cov tshuaj no tau koom ua ke rau hauv cov txheej tiv thaiv sab nraud ntawm cov xov hlau tshwj xeeb ntawm cov chaw soj ntsuam qhov chaw, lawv tuaj yeem tiv taus hluav taws xob cosmic thiab qhov sib txawv ntawm qhov kub thiab txias, ua kom muaj kev sib kis cov ntaub ntawv ruaj khov thaum lub sijhawm ua haujlwm hauv qhov chaw nyuaj.
