Lisebelisoa tsa PPO, joalo ka e 'ngoe ea lipolasetiki tse hlano tse kholo tsa boenjiniere, le tsona ke sehlahisoa se seng se holile haholo sa k'hamphani ea rona. PPO, (polyphony ether)
E na le melemo ea ho tiea ho hoholo, ho hanyetsa mocheso o phahameng, ho thata ho chesa, matla a phahameng le ts'ebetso e ntle ea motlakase. Ho phaella moo, polyether e boetse e na le melemo ea ho roala - ho hanyetsa, ho se chefo, ho thibela - tšilafalo joalo-joalo.
PPO dielectric kamehla le tahlehelo ea dielectric ho polasetiki ea boenjiniere ke e 'ngoe ea mefuta e menyenyane ka ho fetisisa, hoo e batlang e sa angoe ke mocheso, mongobo, e ka sebelisoa tšimong ea tšimo ea motlakase e tlaase, e bohareng, e phahameng.
Tshebetso
1. Likaroloana tse tšoeu. Ts'ebetso e ntle e felletseng e ka sebelisoa ka mouoane oa 120 degree, ho kenya motlakase o motle, ho monya metsi hanyane, empa tloaelo ea khatello ea maikutlo. Khatello ea khatello ea maikutlo e ka felisoa ka polyphenylene ether e fetotsoeng.
2. Motlakase o motle ka ho fetisisa le ho hanyetsa metsi, ho hanyetsa ho apara hantle le ts'ebetso ea motlakase, botsitso bo botle ba dimensional. Thepa ea eona ea dielectric e nka sebaka sa pele ka polasetiki.
3, MPPO ke thepa e fetotsoeng e entsoeng ka ho kopanya PPO le HIPS, hajoale lisebelisoa tse 'marakeng ke mofuta ona oa thepa.
4, e na le mocheso o phahameng oa ho hanyetsa, mocheso oa vitrification oa likhato tse 211, ntlha ea ho qhibiliha ke likhato tse 268, ho futhumatsa ho 330 likhato tse senyehang, dikahare tsa PPO li phahame ho hanyetsa mocheso ho molemo, mocheso oa mocheso o ka fihla ho likhato tse 190.
5. E thibelang malakabe e ntle, e nang le boithatelo, le ho cha ha e kopane le HIPS. Boima bo bobebe, bo seng chefo bo ka sebelisoa indastering ea lijo le lithethefatsi. Ho hanyetsa khanya e fokolang, nako e telele letsatsing e tla fetola 'mala.
6. E ka kopanngoa le ABS, HDPE,PPS,PA,HIPS, fiber ea khalase, joalo-joalo.
Litšobotsi tsa thepa e tala ea PPO
A. PPO lisebelisoa tse tala tse se nang chefo, tse bonaletsang, tse batlang li le nyane, tse nang le matla a matla a mochini, ho hanyetsa khatello ea maikutlo, khanyetso ea creep, ho hanyetsa mocheso, ho hanyetsa metsi, ho hanyetsa metsi, ho hanyetsa mouoane, botsitso ba sebopeho.
B, ka mefuta e mengata ea mocheso le maqhubu a fapaneng, ts'ebetso e ntle ea motlakase, ha e na hydrolysis, ho etsa sekhahla sa ho fokotseha ho nyane, ho ka chesoa ka ho tima, ho hanyetsa ho hanyetsa acid, alkali, monko o monate oa hydrocarbon, halogenated hydrocarbon, oli le thepa e 'ngoe; ho ruruha ha bonolo kapa khatello ea maikutlo.
C. E na le melemo ea ho tiea ho phahameng, ho hanyetsa mocheso o phahameng, ho thata ho chesa, matla a phahameng le ts'ebetso e ntle ea motlakase.
D. Polyether e boetse e na le melemo ea ho hanyetsa abrasion, ho se be chefo le ho hanyetsa tšilafalo.
E. PPO lisebelisoa tse tala tsa polasetiki dielectric kamehla le tahlehelo ea dielectric ka polasetiki ea boenjiniere ke e 'ngoe ea mefuta e menyenyane ka ho fetisisa, hoo e batlang e sa angoe ke mocheso, mongobo, e ka sebelisoa tšimong ea tšimo ea motlakase e tlaase, e bohareng, e phahameng.
F. PPO load deformation mocheso o ka fihla ka holimo ho 190 ℃, mocheso oa embrittlement ke -170 ℃.
G. bofokoli bo boholo ke ho fokola ha metsi a qhibilihang, ho thata ho sebetsa le ho bopa.
Kopo
Ts'ebetso ea PPO e khetholla sebaka sa eona sa ts'ebeliso le mefuta ea ts'ebeliso:
1) MPPO na le segokanyipalo nyenyane, ho le bonolo ho sebetsa, mogote deformation mocheso ka 90 ~ 175 ℃, litlhaloso tse fapaneng tsa thepa, e ntle dimensional botsitso, loketseng bakeng sa ho etsa thepa ea ofisi, lisebelisoa tsa ntlo, lik'homphieutha le mabokose a mang, chassis le likarolo tse nepahetseng.
2) Dielectric constant le dielectric tahlehelo Angle tangent ea MPPO ke e tlaase ka ho fetisisa har'a lipolasetiki tse hlano tsa boenjiniere tse akaretsang, ke hore, ho pata ka ho fetisisa le ho hanyetsa mocheso o motle, o loketseng indasteri ea motlakase.
E loketse tlhahiso ea likarolo tsa ho kenya motlakase tse sebelisoang maemong a metsi le a laetsoeng, joalo ka moralo oa coil, tube base, shaft ea taolo, thebe ea transformer, lebokose la relay, strut ea insulation, jj.
3) MPPO ho hanyetsa metsi le ho hanyetsa mocheso, metsi a matle, a loketseng ho etsoa ha limithara tsa metsi, lipompo.
Thepa ea khoele e sebelisoang fekthering ea masela e lokela ho ba e hanyetsanang le linomoro. Tube ea khoele e entsoeng ke MPPO e na le bophelo bo bolelele ba ts'ebeletso.
4) Dielectric kamehla le tahlehelo ea dielectric Angle tangent ea MPPO ka polasetiki ea boenjiniere ha e amehe ke mocheso le palo ea maqhubu, 'me ho hanyetsa mocheso le botsitso ba dimensional ho molemo, ho loketse indasteri ea elektronike.
5) ka lebaka la nts'etsopele ea indasteri ea lisebelisoa tsa elektroniki le likhokahano, mehala ea thekeng, lilaptop, kh'amera e sebetsang hantle, kh'amera joalo-joalo kaofela li hloka libeteri tsa lithium ion, 'maraka oa betri ea lithium-ion litebello tse kholo tsa nts'etsopele, ka hona, libeteri tsa lithium ion tse nang le organic electrolyte. ea thepa ea ho paka e sebelisitsoeng ABS kapa PC, e ntlafalitsoeng betri MPPO kantle ho naha ka 2013, ts'ebetso ea eona e betere ho feta ea tse peli tsa pele.
6) MPPO e na le mefuta e mengata ea li-USES indastering ea likoloi, joalo ka dashboard, li-bars tse sireletsang, PPO le PA alloy, haholo-holo bakeng sa litlhaloso tse phahameng tsa ts'ebetso bakeng sa nts'etsopele e potlakileng ea likarolo.
7) Lefapheng la lik'hemik'hale, polyphenylene ether e fetotsoeng e ka sebelisoa ho etsa lisebelisoa tse thibelang ho bola; ho hanyetsa ha eona ho hydrolysis e ntle haholo, empa hape le asiti, alkali, e qhibilihang ka har'a hydrocarbon e nkhang hamonate le hydrocarbon e chlorinated.
8) Bakeng sa lisebelisoa tsa bongaka, li ka nka sebaka sa tšepe e sa hloekang le litšepe tse ling ka tanka ea polokelo ea metsi a chesang le valafo e tsoang ho fan e tsoakiloeng.
