4,4′-Biphenol CAS: 92-88-6

4,4'-Biphenol siv tau rau ntau yam kev siv vim nws muaj ntau yam khoom siv. Ib qho ntawm nws cov kev siv tseem ceeb yog ua ib lub monomer hauv kev tsim cov yas engineering xws li polyesters, polycarbonates, thiab polyarylates. Cov ntaub ntawv no pom cov ntawv thov hauv kev lag luam xws li tsheb, hluav taws xob thiab hluav taws xob, thiab aerospace vim lawv lub zog zoo heev, tiv taus cua sov, thiab cov khoom hluav taws xob. Ntxiv mus, 4,4'-Biphenol ua haujlwm ua lub hauv paus hauv kev tsim cov kua siv lead ua kua, uas siv rau hauv ntau yam thev naus laus zis tso saib, suav nrog cov kua siv lead ua kua (LCDs) thiab cov organic teeb-emitting diodes (OLEDs). Nws lub peev xwm los tsim cov kua siv lead ua kua ua rau nws muaj txiaj ntsig zoo hauv kev txhim kho cov khoom siv hluav taws xob siab heev nrog kev ua tau zoo dua thiab ua haujlwm tau zoo. Ntxiv mus, 4,4'-Biphenol siv rau hauv kev tsim cov epoxy resins, uas siv dav ua cov nplaum, txheej, thiab cov ntaub ntawv tsim kho hauv ntau yam kev lag luam. Nrog nws lub peev xwm los hloov kho cov khoom ntawm epoxy formulations, 4,4'-Biphenol pab txhawb kev txhim kho ntawm lub zog nplaum, tshuaj lom neeg tiv taus, thiab thermal stability. Ntxiv mus, cov tshuaj no pom tau tias siv tau rau hauv kev tsim cov polymers tshwj xeeb nrog cov khoom tsim tshwj xeeb rau cov kev xav tau tshwj xeeb hauv kev lag luam. Los ntawm kev koom ua ke 4,4'-Biphenol rau hauv cov polymer matrices, cov chaw tsim khoom tuaj yeem ua tiav cov yam ntxwv ntawm cov khoom siv, xws li kev pom tseeb siab, tiv taus UV, thiab hluav taws kub, ua kom tau raws li ntau yam kev xav tau thoob plaws ntau qhov kev lag luam. Hauv kev xaus, 4,4'-Biphenol yog ib qho tseem ceeb hauv kev tsim cov polymers siab heev, cov kua siv lead ua kua, thiab cov ntaub ntawv tshwj xeeb, txhawb nqa ntau yam kev lag luam nrog cov kev daws teeb meem tshiab rau kev siv ua haujlwm siab. Nws cov qauv tshuaj lom neeg tshwj xeeb thiab kev ua haujlwm ntau yam ua rau nws yog ib qho tseem ceeb hauv kev tsim cov khoom siv tshiab rau kev siv thev naus laus zis niaj hnub thiab kev lag luam.
