Khoom siv
3,3 ',4,4 '-Biphenyl tetracarboxylic diandhydride, lwm yam hu ua BPDA, CAS 2420-87-3, yog ib qho organic compound feem ntau siv rau hauv kev sib txuas ntawm cov khoom siv polymers siab. BPDA feem ntau yog siv hauv cov hauv qab no:
1, cov khoom siv polyimide: BPDA yog ib qho tseem ceeb monomers rau kev npaj ntawm Polyimides. Polyimide muaj kev ruaj ntseg zoo heev, cov khoom siv kho tshuab thiab tshuaj lom neeg ruaj khov, thiab yog siv dav hauv aerospace, microelectronics ntim, kub kub Circuit Court board thiab lwm yam teb.
2,laminate: Hauv kev tsim cov laminate ua haujlwm siab, BPDA tuaj yeem siv los txhim kho cov cua sov thiab hluav taws xob rwb thaiv tsev ntawm cov khoom.
3, coatings thiab xim: BPDA tuaj yeem siv los tsim cov txheej txheem ua haujlwm siab thiab cov xim uas muaj kev ua tau zoo txawm tias nyob rau hauv cov xwm txheej hnyav.
4,fiber ntau reinforced plastics (FRP): Qee zaum, BPDA kuj tseem siv los txhim kho kev ua haujlwm ntawm FRP cov ntaub ntawv, ua rau nws tsim nyog rau cov ntawv thov hauv qhov kub thiab txias.
5, Lwm yam kev ua haujlwm siab polymers: Ntxiv rau polyimide, BPDA kuj tuaj yeem siv los ua lwm cov khoom siv hluav taws xob zoo xws li polyether imide (PEI) cov khoom siv raw khoom.

FAQ
1. Dab tsi yog qhov tseem ceeb ntawm BPDA?
Raws li tau hais ua ntej, BPDA feem ntau yog siv los ua monomer rau kev ua haujlwm siab polymers xws li polyimides, uas tau siv dav hauv kev lag luam xws li electronics, aviation, thiab coatings tshwj xeeb.
2. Dab tsi yog qhov chaw cia khoom rau BPDA?
BPDA yuav tsum tau muab cia rau hauv qhov chaw qhuav, txias thiab yuav tsum tau khaws cia kom deb ntawm huab cua thiab noo noo kom tsis txhob muaj cov tshuaj tiv thaiv lossis degradation.
3. Kev ceev faj rau BPDA yog dab tsi?
Thaum tuav BPDAs, koj yuav tsum ua raws li cov txheej txheem kev ua haujlwm nyab xeeb, hnav cov khoom tiv thaiv tus kheej tsim nyog (PPE), thiab xyuas kom meej tias thaj chaw ua haujlwm yog qhov cua zoo.
