1. Cov tsos thiab cov khoom:

Peb 4,4-chloroformylphenylene ether nthuav tawm lub cev zoo kawg nkaus.Nws zoo nkaus li cov hmoov daj daj, muaj cov thermal stability zoo heev thiab ua rau cov tshuaj degradation.CFPE muaj qhov melting point ntawm kwv yees li 180°C thiab boiling point ntawm 362°C. Nws yog soluble hauv cov kuab tshuaj xws li chlorinated hydrocarbons, cawv, thiab ethers.

2. Kev siv:

4,4-chloroformylphenylene ether yog dav siv los ua lub tsev tseem ceeb hauv kev sib txuas ntawm ntau yam kev ua haujlwm siab polymers, xws li polyphenylene sulfide (PPS) thiab polyether ether ketone (PEEK).Cov polymers no tau nrhiav-tom qab rau lawv qhov tshwj xeeb thermal stability, mechanical zog, thiab tshuaj tiv thaiv, ua rau lawv zoo tagnrho rau kev thov kev lag luam.

3. Ntxiv nta thiab txiaj ntsig:

- Cov tshuaj tiv thaiv kev ua haujlwm siab: CFPE cov qauv tshuaj tso cai rau kev koom ua ke zoo rau hauv cov saw hlau polymer, ua rau cov khoom ua tau zoo dua qub.

- Txhim kho cov nplaim hluav taws-retardancy: CFPE-muaj cov polymers pom cov nplaim taws zoo heev, ua rau lawv tsim nyog rau cov ntawv thov kom muaj kev nyab xeeb hluav taws.

- Chemical inertness: Cov khoom tshwj xeeb ntawm CFPE ua rau nws tiv taus ntau cov tshuaj corrosive, ua kom lub neej ntev ntawm cov khoom kawg.

4. Ntim thiab tuav:

Peb 4,4-chloroformylphenylene ether tau ntim rau hauv cov thawv ntim cua kom ntseeg tau tias nws ruaj khov thaum thauj thiab khaws cia.Nws raug nquahu kom khaws cov khoom hauv qhov chaw txias, qhuav kom deb ntawm lub hnub ncaj qha thiab cov khoom tsis sib xws.Cov txheej txheem tuav kom raug yuav tsum tau ua raws li kev thauj mus los thiab kev siv kom muaj kev nyab xeeb siab tshaj plaws thiab tiv thaiv kev pheej hmoo ntawm kev kis kab mob.
