Daim ntawv thov
1. Pab 4 4'-Diaminobenzanilide ua ib qho tseem ceeb monomer rau kev sib txuas siab -lub zog muaj zog polyamides thiab polyimide resins nrog thermal stability zoo.
2. Siv DABA hauv kev tsim khoom siab -kev ua haujlwm fibers thiab cov yeeb yaj kiab siv hauv kev lag luam aerospace, automotive thiab filtration industries.
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 thiab cov neeg kho tshuab toughness.
Cia thiab ceev faj
4 4'-Diaminobenzanilide 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 DABA CAS 785-30-8 cais tawm ntawm cov kua qaub uas muaj zog, cov oxidizing cov neeg ua haujlwm thiab cov dej noo kom tsis txhob muaj tshuaj lom neeg, tsis muaj xim thiab degradation zoo.
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 DABA?
DABA CAS 785-30-8 yog ib qho tseem ceeb monomer rau kev sib txuas ua haujlwm siab uas muaj ntxhiab polyamides thiab polyimides. Cov polymers no muaj kev ruaj ntseg zoo heev, txhua yam muaj zog thiab tshuaj lom neeg ua haujlwm, ua rau lawv zoo tagnrho rau kev tsim cov khoom siv hauv aerospace, muaj zog muaj fiber ntau thiab cov khoom siv ruaj khov uas ua tau zoo hauv kev ua haujlwm hnyav.
