Tam sim ntawd thiab tshwj xeeb tom qab-muag kev pab cuam muab los ntawm peb pab pawg neeg pab tswv yim tau zoo siab rau peb cov neeg yuav khoom. Hauv qhov tob Info thiab parameters los ntawm cov khoom muag tej zaum yuav raug xa tuaj rau koj kom paub meej meej. Cov qauv dawb tuaj yeem xa tuaj thiab lub tuam txhab tshawb xyuas rau peb lub tuam txhab. n Portugal rau kev sib tham yog lossi txais tos. Cia siab tias yuav tau txais cov lus nug ntaus koj thiab tsim kom muaj kev sib koom tes ua haujlwm ntev.
Cov pyromellitic dianhydride (abbreviated li PMDA), uas yog tsuas yog siv rau synthesis ntawm polyimide, vim hais tias polyimide muaj zoo heev ultra-siab kub tsis kam, acid thiab alkali tsis kam, zoo heev vim hais tias ntawm nws mechanical zog, hluav taws xob zog thiab seem stability, nws yog dav. siv nyob rau hauv high-tech teb xws li aviation, aerospace, microelectronics thiab atomic zog, uas yuav tsum nruj me ntsis rau cov khoom siv.

Pyromellitic dianhydride (PMDA) yog ib qho tseem ceeb raw khoom nyob rau hauv kev lag luam organic synthesis, nrog rau cov khoom siv raw rau kev tsim cov khoom siv tshuaj tshiab thiab cov khoom muaj txiaj ntsig zoo ntxiv. Nws yog tsuas yog siv rau zus tau tej cov polyimide monomers, thiab kuj yuav siv tau raws li ib tug Curing neeg sawv cev rau epoxy resin thiab cross-linking tus neeg saib xyuas rau polyester cob, siv nyob rau hauv lub tsim ntawm phthalocyanine xiav dye thiab ib co tseem ceeb derivatives, thiab lwm yam., thiab muaj ntau yam kev siv. Pyromellitic dianhydride, tseem hu ua homoanhydride, muaj cov qauv molecular tshwj xeeb thiab tuaj yeem siv los tsim cov ntaub ntawv nrog cov khoom siv hluav taws xob, hluav taws xob rwb thaiv tsev thiab tshuaj lom neeg, cov khoom siv tseem ceeb tshaj plaws yog cov monolayer ntawm polyimide. Nws yog synthesized nrog aromatic diamine kom tau polyimide yas, tab sis lub purity ntawm pyromellitic dianhydride yog siab heev, uas yuav tsum tau ntau tshaj 99%.
