Daim ntawv thov

1. Ua haujlwm raws li cov tub ntxhais monomer rau kev sib txuas siab -lub zog muaj zog polyamides thiab polyimides siv hauv cov fibers thiab cov yeeb yaj kiab.

2. Ua haujlwm 4 4'-Ethylenedianiline ua ib qho tseem ceeb nruab nrab ntawm kev tsim cov xim tshwj xeeb, xim xim thiab UV-cov coatings ruaj khov rau cov tsheb thiab kev tsim kho.

3. Ua haujlwm raws li tus neeg sawv cev kho rau epoxy resins txhawm rau txhim kho qhov kub thiab txias ntawm cov khoom siv sib xyaw.

Cia thiab ceev faj

Khaws 4 4'-Ethylenedianiline nyob rau hauv ib lub thawv kaw, lub teeb- tiv taus qhov kub ntawm 10–20℃hauv qhov txias, qhuav, zoo- qhov cua qhov chaw, deb ntawm qhov chaw tshav ntuj ncaj qha thiab qhov chaw sov. Cais nws los ntawm acids, oxidants thiab noo noo los tiv thaiv decomposition thiab discoloration.

Hnav cov tshuaj lom neeg- hnab looj tes tiv thaiv, daim npog ntsej muag thiab daim npog ntsej muag thaum tuav. Tsis txhob nqus plua plav thiab tiv thaiv daim tawv nqaij. Rov kho lub thawv tam sim tom qab siv thiab pov tseg cov pov tseg raws li cov cai hauv zos muaj kev phom sij.

Dab tsi yog qhov txiaj ntsig ntawm kev noj 4 4'-Ethylenedianiline?

4 4'-Ethylenedianiline ua ib qho tseem ceeb monomer rau synthesizing siab -kev ua tau zoo ntawm polyamides thiab polyimides nrog tshwj xeeb thermal kuj thiab txhua yam muaj zog, uas yog siv nyob rau hauv manufacturing industrial fibers thiab siab - kub resistant films. Tsis tas li ntawd, nws ua haujlwm ua tus neeg saib xyuas zoo rau epoxy resins, txhim kho cov tshuaj tiv thaiv ntawm cov ntaub ntawv sib xyaw siv hauv aerospace thiab automotive fields.
