4,4'-Oxydiphthalic anhydride (ODPA) yog ntau yam tshuaj nruab nrab uas muaj ntau yam kev siv hauv kev tsim khoom ntawm ntau yam khoom. ODPA CAS 1823-59-2 yog cov hmoov dawb crystalline uas yog tsim los ntawm cov tshuaj tiv thaiv ntawm phthalic anhydride thiab phenols.
4,4'-Oxydiphthalic anhydride cas 1823-59-2 yog ib qho tseem ceeb nruab nrab ntawm kev tsim cov khoom siv hluav taws xob zoo xws li polyimides, polyesters, thiab epoxy resins. Cov polymers no muaj cov khoom siv zoo heev, thermal, thiab tshuaj lom neeg, ua rau lawv muaj txiaj ntsig zoo hauv ntau yam kev siv xws li aerospace, electronics, thiab automotive industries.
Polyimides yog cov kub-resistant polymers uas yog siv nyob rau hauv daim ntaub ntawv uas yuav tsum tau zoo heev mechanical zog. Qee qhov piv txwv ntawm cov ntawv thov no muaj xws li bearings, gears, thiab seals. 4,4'-Oxydiphthalic anhydride cas 1823-59-2 yog ib qho tseem ceeb nruab nrab siv hauv kev tsim cov polyimides xws li PMDA-ODA, BPDA-ODA, thiab BPDA-PDA.
Epoxy resins yog siv los ua cov nplaum, txheej, thiab cov khoom sib xyaw hauv ntau yam lag luam.ODPA CAS 1823-59-2yog siv los tsim cov epoxy resins xws li bisphenol A-type epoxy resins thiab novolac-type epoxy resins. Cov resins no muaj adhesion zoo, siab zog, thiab tshuaj tiv thaiv uas ua rau lawv haum rau siv nyob rau hauv kev tsim kho, marine, thiab hluav taws xob industries.
Polyesters yog lwm hom polymer uas tuaj yeem tsim siv ODPA ua ib qho nruab nrab. Cov polymers no muaj lub zog siab, ruaj khov, thiab yoog raws, ua rau lawv muaj txiaj ntsig zoo rau ntau yam kev siv xws li textile fibers, ntim khoom, thiab coatings.
ODPA kuj tseem siv rau hauv kev tsim cov yas yas xws li ortho-phthalate esters. Cov plasticizers no tau ntxiv rau cov polymers txhawm rau ua kom lawv yooj yim dua thiab ua haujlwm ntev. ODPA-based plasticizers muaj qhov ua tau zoo ntawm qhov kub thiab txias thiab siv rau hauv cov ntawv thov uas qhov yooj yim yog qhov tseem ceeb.
Ntxiv rau nws siv hauv kev tsim cov polymers thiab plasticizers,4,4'-Oxydiphthalic anhydride CAS 1823-59-2yog siv los ua hluav taws kub retardant hauv kev tsim cov khoom siv hluav taws xob thiab hluav taws xob. Nws tseem tuaj yeem siv los ua tus neeg sawv cev sib txuas hauv kev tsim cov nplaum, txheej, thiab lwm yam khoom.
Hauv kev xaus,4,4'-Oxydiphthalic anhydride CAS 1823-59-2yog ntau yam tshuaj nruab nrab uas muaj ntau yam kev siv tseem ceeb hauv ntau yam kev lag luam. Nws siv hauv kev tsim cov khoom siv zoo polymers, plasticizers, nplaim retardants, thiab lwm yam khoom tau pab txhawb rau kev nce qib ntawm ntau yam thev naus laus zis. Vim nws cov khoom tshwj xeeb thiab ntau yam kev siv, ODPA yog ib qho tseem ceeb ntawm cov tshuaj nruab nrab uas zoo li yuav ua lub luag haujlwm tseem ceeb hauv kev txhim kho yav tom ntej ntawm ntau yam kev lag luam.
