1. Ua haujlwm 2 3 6 7-Naphthalenetetracarboxylic2 3 6 7-dianhydride ua lub siab- purity dianhydride monomer rau kev sib xyaw ua ke ntawm cov cua sov-cov tshuaj tiv thaiv polyimide siv hauv aerospace thiab cov khoom siv hluav taws xob.

2. Ua haujlwm rau NTCDA ua tus thawj coj ua haujlwm rau kev tsim cov yeeb yaj kiab dielectric nrog cov hluav taws xob rwb thaiv tsev ua haujlwm zoo rau siab - cov khoom siv zaus.

3. Kev ua haujlwm raws li lub tsev tseem ceeb hauv kev tsim cov khoom sib xyaw ua ke thiab cov txheej txheem tshwj xeeb uas tiv taus qhov kub thiab txias thiab tshuaj lom neeg.

Store NTCDA in a sealed aluminum-lined container at 0–5℃under refrigerated conditions, away from direct sunlight, humidity and heat sources. Kev sib cais nruj me ntsis 2 3 6 7-Naphthalenetetracarboxylic2 3 6 7-dianhydride los ntawm amines, cawv thiab cov hauv paus muaj zog los tiv thaiv hydrolysis thiab polymerization ntxov ntxov uas txo cov purity.

Hnav cov kua qaub- cov hnab looj tes tiv thaiv, ib daim npog tag nrho - lub ntsej muag thiab lub tshuab nqus plua plav thaum tuav. Tsis txhob nqus plua plav thiab tiv thaiv daim tawv nqaij. Reseal tam sim ntawd tom qab siv thiab pov tseg cov pov tseg raws li cov txheej txheem pov tseg tshuaj lom neeg hauv zos.

Raws li lub siab -kev ua tau zoo dianhydride, NTCDA txhim kho cov thermal stability thiab tshuaj tiv thaiv ntawm polyimide resins siv nyob rau hauv aerospace thiab siab -frequency electronic Cheebtsam. 2 3 6 7-Naphthalenetetracarboxylic2 3 6 7-dianhydride kuj txhim kho cov dielectric zog ntawm tshwj xeeb zaj duab xis thiab durability ntawm ib puag ncig cov ntaub ntawv.
