Daim ntawv thov
1. Ua haujlwm 3 3'-Sulfonyldianiline CAS 599-61-1 ua cov monomer tseem ceeb rau kev sib txuas ntawm sulfone-based polyamide thiab polyimide polymers nrog thermal stability.
2. Siv 3 3'-Sulfonyldianiline hauv kev tsim khoom siab-kev ua haujlwm engineering yas siv hauv kev lag luam aerospace, tsheb thiab hluav taws xob.
3. Siv los ua tus ntoo khaub lig- txuas tus neeg sawv cev rau kev hloov kho epoxy resins los txhim kho lawv cov tshuaj tiv thaiv corrosion thiab lub zog txhua yam.
Cia thiab ceev faj
3 3'-Sulfonyldianiline should be stored in a tightly sealed, light-resistant container at 15–25℃, in a cool, dry and well-ventilated area away from direct sunlight and heat sources. Khaws nws cais tawm ntawm cov kua qaub uas muaj zog, oxidizing cov neeg ua haujlwm thiab cov dej noo los tiv thaiv cov tshuaj lom neeg uas ua rau kom tsis zoo los yog tsis muaj xim.
Thaum tuav, hnav cov tshuaj lom neeg-cov hnab looj tes tiv thaiv, tsom iav thiab lub tsho tiv thaiv, thiab ua haujlwm hauv lub hood 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.
Dab tsi yog qhov txiaj ntsig ntawm kev noj 3 3'-Sulfonyldianiline?
3 3'-Sulfonyldianiline yog ib qhoindustrial organic intermediate, feem ntau yog siv rau hauv kev sib txuas siab -kev ua tau zoo polymers xws li sulfone-raws li polyamides thiab polyimides. Cov polymers pom zoo thermal stability, tshuaj tiv thaiv thiab txhua yam muaj zog, uas muaj txiaj ntsig zoo rau kev tsim cov khoom siv hluav taws xob, hluav taws xob rwb thaiv tsev thiab cov khoom siv tsheb.
