Daim ntawv thov
9 9-Bis(3-methyl-4-hydroxyphenyl) fluoreneCAS: 88938-12-9) yog cov ntaub ntawv tseem ceeb chemistry, uas yog siv dav hauv ntau yam kev lag luam thiab kev tshawb fawb.
Nws cov ntawv thov tseem ceeb yog raws li hauv qab no:
1. 9 9-Bis(3-methyl-}4-hydroxyphenyl) fluorene yog ib qho kev ua haujlwm siab thiab cov monomer rau cov khoom siv hluav taws xob epoxy resins siv hauv cov khoom siv hluav taws xob thiab cov khoom siv PCB.
2. 9 9-Bis(3-methyl-4-hydroxyphenyl) fluorene yog ib qho tseem ceeb raw khoom rau synthesizing polycarbonate, polyimide thiab lwm yam high heat-resistant engineering yas resins.
3. 9 9-Bis(3-methyl-}4-hydroxyphenyl) fluorene yog ib qho kev ua haujlwm nruab nrab rau kev npaj cov khoom siv hluav taws xob tsis zoo thiab cov txheej txheem kub-resistant txheej binders.
Cia
1. Khaws cov khoom kaw hauv qab 25℃hauv lub txee tsaus ntuj kom tiv thaiv oxidation ntawm phenolic hydroxyl pawg ntawm cov benzene rings.
2. Txwv tsis pub qhib lub ntim ntau zaus kom tsis txhob muaj xim liab liab tshwm sim los ntawm cov pa oxygen thiab dej vapor hauv huab cua ambient.
3. Khaws cov tshuaj no sib cais los ntawm cov oxidants muaj zog thiab muaj zog alkaline tshuaj kom tsis txhob muaj phenolic ntsev tsim thiab molecular degradation.
Cov txiaj ntsig ntawm Kev Siv
1. Dual phenolic hydroxyl pawg tuaj yeem ua epoxy nplhaib - qhib cov tshuaj tiv thaiv rau crosslink thiab kho epoxy resin tshuab tau zoo.
2. Cov pob txha fluorene rigid pob txha zoo heev txhim kho qhov kub thiab txias, iav hloov kub thiab qhov ruaj khov ntawm cov polymers kho.
3. Methyl substituents txhim khu lub solubility ntawm lub monomer nyob rau hauv cov organic solvents uas tsis ua rau tag nrho cov thermal kev ua tau zoo.
Cov ntaub ntawv kev nyab xeeb
1. Thaiv nqus tau cov hmoov zoo crystalline hmoov; hnav plua plav qhov ncauj qhov ntswg thiab cov hnab looj tes chemical resistant thaum lub sij hawm hnyav thiab tuav cov khoom.
2. Cov tshuaj no ua rau mob me me rau ntawm daim tawv nqaij thiab cov ntaub so ntswg mucous; ntxuav cov chaw uas muaj kab mob nrog dej txaus tom qab kev sib cuag.
3. Muab pov tseg cov khib nyiab thiab cov kua dej pov tseg raws li cov cai tswj cov khib nyiab pov tseg rau fluorene-raws li bisphenol compounds.
