Polyphenylene oxide kapa polyethylene ether E boetse e tsejoa e le polyphenylene oxide kapa polyphenylene ether, ke resin ea thermoplastic e hanyetsanang le mocheso o phahameng.
Litšobotsi le Lisebelisoa
PPO ke polasetiki ea boenjiniere ea thermoplastic e nang le ts'ebetso e phethahetseng e felletseng, ho kenella ka motlakase ho ikhethang le ho hanyetsa metsi, le botsitso bo botle ba sebopeho.
1, thepa ea dielectric ea polasetiki ea boenjiniere pele
Sebopeho sa limolek'hule tsa PPO ntle le lihlopha tse matla tsa polar, thepa ea motlakase e tsitsitseng, e ka boloka thepa e ntle ea motlakase ka mefuta e mengata ea mocheso le maqhubu.
① Dielectric constant: 2.6-2.8 ke e nyane ka ho fetisisa ho lipolasetiki tsa boenjiniere ② Tangent ea tahlehelo ea dielectric Angle: 0.008-0.0042 (hoo e batlang e sa angoe ke mocheso, mongobo le maqhubu) ③ Restivity ea molumo: 1016 ke eona e phahameng ka ho fetisisa ea polasetiki ea boenjiniere
2, thepa e ntle ea mochini le e futhumatsang ea ketane ea limolek'hule ea PPO, e nang le palo e kholo ea sebopeho sa selikalikoe se nkhang hamonate, kutlo ea limolek'hule tsa ketane e matla, matla a mochini oa resin a phahame, khanyetso e ntle ea creep, phetoho ea mocheso e nyane haholo.PPO e na le khanyetso e phahameng ea mocheso, mocheso oa phetoho oa khalase ho fihla ho 211 ℃, ntlha e qhibilihang ke 268 ℃.
3, khanyetso e ntle ea metsi PPO ke resin e seng kristale, maemong a tloaelehileng a mocheso, motsamao o fokolang oa limolek'hule, ha ho na lihlopha tse kholo tsa polar ka ketane e kholo, motsotso oa dipole ha o etsahale poleiti, ho hanyetsa metsi ho molemo haholo, ke sekhahla se tlase sa ho monya metsi. ea mefuta ea lipolasetiki tsa boenjiniere.Sebopeho sa eona sa 'mele se ntse se e-na le ho senyeha ho fokolang ka mor'a ho koloba metsing a chesang nako e telele.
4, Index ea oksijene ea PPO e itimang ka boeona ke 29, e leng thepa ea ho itima lijo, 'me index ea oksijene ea polyethylene e nang le tšusumetso e phahameng ke 17, e leng thepa e tukang.Motsoako oa bobeli ke oa ho chesa ho itekanetseng.Ha o etsa PPO e thibelang malakabe, ha ho hlokahale hore u kenye halogen flame retardant, ho eketsa lethal dose le nang le phosphorus le nang le lelakabe le ka fihla ho UL94 standard.Fokotsa tšilafalo tikolohong.
5, sekhahla se tlase sa shrinkage, botsitso bo botle ba sebopeho;E se nang chefo, e tlaase ea 6, ho hanyetsa dielectric le ho hanyetsa khanya PPO acid, alkali le detergent le tse ling tsa motheo tsa kutu, tlas'a boemo ba khatello ea kelello, oli ea diminerale le ketone, li-solvents tsa ester li tla hlahisa khatello ea kelello;Li-solvents tse kang aliphatic hydrocarbons, halogenated aliphatic hydrocarbons le li-hydrocarbon tse nkhang hamonate li ka qhibiliha le ho qhibiliha.
Bofokoli ba PPO ke ho hanyetsa khanya ha nako e telele, nako e telele tlas'a khanya ea letsatsi kapa tšebeliso ea lebone la fluorescent e hlahisa mebala, 'mala o mosehla, lebaka ke hore leseli la ultraviolet le ka etsa hore ketane ea ether e nkhang hamonate e arohane.Mokhoa oa ho ntlafatsa khanyetso ea leseli ea PPO e fetoha sehlooho.
Ts'ebetso ea PPO e khetha sebaka le boholo ba kopo:
①MPPO density e nyane, ho bonolo ho e sebetsa, mocheso oa deformation oa mocheso ho 90-175 ℃, ho na le litlhaloso tse fapaneng tsa thepa, botsitso bo botle ba sebopeho, bo loketseng ho etsoa ha lisebelisoa tsa ofisi, lisebelisoa tsa ntlo, mabokose a khomphutha, chassis le likarolo tse nepahetseng.
② MPPO dielectric kamehla le tahlehelo ea dielectric Angle tangent ho li-plastiki tse hlano tse akaretsang tsa boenjiniere tse tlase ka ho fetisisa, ke hore, sekontiri se setle ka ho fetisisa, le ho hanyetsa mocheso o motle, o loketseng indasteri ea motlakase.E loketse ho etsa likarolo tse sireletsang motlakase, tse kang foreimi ea li-coil, sets'oants'o sa tube, shaft ea taolo, sleeve ea thebe ea transformer, lebokose la relay, pilara e sireletsang joalo-joalo, e sebelisoang maemong a metsi le a laetsoeng.
③ MPPO e na le ho hanyetsa metsi hantle le ho hanyetsa mocheso, e loketseng ho etsa limithara tsa metsi, lipompo tsa metsi le li-tubes tsa likhoele tse sebelisoang lifekthering tsa masela tse hlokang thepa e tšoarellang ea bareki bakeng sa ho pheha.Li-tubes tsa khoele tse entsoeng ka MPPO li na le bophelo bo bolelele ba ts'ebeletso.
④ The dielectric constant le dielectric loss Angle tangent ea MPPO ha e amehe ke mocheso le nomoro ea potoloho ka lipolasetiki tsa boenjiniere, 'me li na le ho hanyetsa mocheso o motle le botsitso ba dimensional, tse loketseng indasteri ea elektroniki.
