Daim ntawv thov
1. Ua raws li ib qho tseem ceeb monomer rau synthesizing tshav kub-resistant polyimide resins siv nyob rau hauv siab -kev ua tau zoo hluav taws xob thiab aerospace cov ntaub ntawv.
2. Pab Cyclobutane-1 2 3 4-tetracarboxylic dianhydride ua tus ntoo khaub lig- txuas tus neeg sawv cev rau kev hloov kho epoxy resins los txhim kho lawv cov thermal stability thiab txhua yam muaj zog.
3. Kev ua haujlwm raws li lub tsev thaiv hauv kev sib txuas ntawm cov polymers tshwj xeeb nrog cov tshuaj tiv thaiv zoo heev thiab dielectric zog.
Cia thiab ceev faj
Cyclobutane-1 2 3 4-tetracarboxylic dianhydride yuav tsum muab cia rau hauv lub thawv kaw nruj nreem ntawm 15-25 degree, nyob rau hauv qhov txias, qhuav, thiab zoo- qhov cua qhov chaw kom deb ntawm tshav ntuj ncaj qha. Nws yog rhiab heev rau cov dej noo, yog li khaws nws kom deb ntawm qhov chaw ntub dej kom tsis txhob muaj hydrolysis thiab qhov tsis zoo.
Thaum tuav, hnav cov tshuaj lom neeg- cov hnab looj tes tiv thaiv, tsom iav, thiab lub tsho hauv chav kuaj, thiab ua haujlwm hauv lub hood fume kom tsis txhob nqus plua plav thiab qhov muag / qhov muag. Tshem lub thawv tam sim tom qab siv. Kev pov tseg pov tseg nruj me ntsis raws li cov cai tswj kev phom sij hauv zos.
