4,4′-Oxydaniline CAS 101-80-4
Raws li cov khoom siv tshwj xeeb engineering, polyimide muaj qhov zoo ntawm qhov kub thiab txias, tiv thaiv hluav taws xob thiab lub zog txhua yam. Nws yog siv nyob rau hauv films, coatings, fibers, aerospace, hluav taws xob thiab hluav taws xob industries, foamed plastics thiab photoresists. 4,4'-Diaminodiphenyl ether yog ib qho ntawm cov khoom siv tseem ceeb. Nyob rau tib lub sijhawm, 4,4'-diaminodiphenyl ether tuaj yeem siv los tsim tus neeg sawv cev sib txuas, thiab tau siv dav los hloov cov carcinogenic benzidine los tsim azo dyes thiab reactive dyes. Yog li, 4,4'-diaminodiphenyl ether yog ib qho nruab nrab nrog tus nqi ntxiv.

1. Nws yog ib qho tseem ceeb raw khoom rau tshiab tshwj xeeb engineering yas xws li polyimide, polyetherimide, polyesterimide, polymaleimide, polyaramid thiab lwm yam kub resistant resins;
2. Nws kuj yog synthesized. Cov khoom siv raw ntawm 3,3',4,4'-tetraaminodiphenyl ether, uas yog lub ntsiab monomer rau kev npaj cov khoom muaj ntxhiab heterocyclic kub-resistant polymer cov ntaub ntawv.
3. Nws kuj tseem siv los ua cov khoom siv raw thiab tus neeg sawv cev sib txuas rau kev ua haujlwm siab kub-resistant epoxy resin, polyurethane thiab lwm yam hluavtaws polymers.
4. Nws kuj tseem siv los hloov cov carcinogenic benzidine hauv kev tsim cov azo dyes, reactive dyes thiab fragrances. Tam sim no, siv diaminodiphenyl ether ua raw khoom, ncaj qha dyes ntawm cov xim sib txawv xws li ci liab, ci liab, xuab zeb liab, daj-xim av, ntsuab, grey, xiav, ci ntsa iab txiv kab ntxwv thiab dub tau tsim, uas yuav siv tau rau. txhob lo lo ntxhuav, ntaub plaub, paj rwb, dyeing ntawm hemp thiab lwm yam ntaub yog superior rau benzidine dyes nyob rau hauv cov nqe lus ntawm cov xim ceev ceev thiab qaug zog npaum li cas.
