Ukusebenza okuphezulu kwe-PPO evela ku-SIKO.

Impahla ye-PPO evela ku-SIKO

I-Polyphenylene oxide noma i-polyethylene ether Eyaziwa nangokuthi i-polyphenylene oxide noma i-polyphenylene ether, i-resin ye-thermoplastic emelana nezinga lokushisa eliphezulu.

Izici kanye nezicelo

I-PPO iyipulasitiki yobunjiniyela be-thermoplastic esebenza kahle kakhulu, i-insulation kagesi evelele kanye nokumelana namanzi, kanye nokuzinza okuhle kwe-dimensional.

1, izakhiwo ze-dielectric zamapulasitiki wobunjiniyela kuqala

Isakhiwo se-molecular PPO resin ngaphandle kwamaqembu aqinile we-polar, izakhiwo zikagesi ezizinzile, zingagcina izakhiwo ezinhle zikagesi ebangeni elibanzi lokushisa kanye nemvamisa.

① I-Dielectric constant: 2.6-2.8 incane kunawo wonke kumapulasitiki obunjiniyela ② I-Tangent yokulahleka kwe-dielectric I-engeli: 0.008-0.0042 (cishe ayithinteki izinga lokushisa, umswakama kanye nemvamisa) ③ Ukumelana nomthamo: 1016 iphakeme kakhulu kumapulasitiki obunjiniyela

I-2, izakhiwo ezinhle zemishini nezokushisa zeketanga le-PPO lamangqamuzana, eliqukethe inani elikhulu lesakhiwo sendandatho enephunga elimnandi, ukuzwela kweketango lamangqamuzana kunamandla, amandla emishini e-resin aphezulu, ukumelana okuhle kakhulu kokukhasa, ukuguquka kwezinga lokushisa kuncane kakhulu. I-PPO inokumelana nokushisa okuphezulu, izinga lokushisa lokushintsha kwengilazi lifika ku-211 ℃, iphuzu elincibilikayo lingu-268 ℃.

I-3, ukumelana namanzi okuhle kakhulu i-PPO iyi-resin engeyona i-crystalline, ebangeni lokushisa elijwayelekile, ukunyakaza okuncane kwamangqamuzana, awekho amaqembu amakhulu e-polar eketangeni eliyinhloko, umzuzu we-dipole awenzeki isigxobo, ukumelana kwamanzi kuhle kakhulu, izinga lokumunca amanzi eliphansi kakhulu. izinhlobo zepulasitiki zobunjiniyela. Izakhiwo zayo ezibonakalayo zisenokonakala okuncane ngemva kokucwiliswa emanzini ashisayo isikhathi eside.

I-4, Inkomba ye-oxygen ye-PPO yokuzicisha yi-29, okuyizinto ezizicishayo, futhi inkomba ye-oksijini ye-polyethylene enomthelela omkhulu yi-17, okuyizinto ezivuthayo. Inhlanganisela yakho kokubili iwukuvutha okumaphakathi. Uma wenza i-PPO ebuyisela amalangabi, asikho isidingo sokwengeza i-halogen flame retardant, ukwengeza umthamo we-phosphorus-container flame retardant kungafinyelela izinga le-UL94. Yehlisa ukungcoliswa kwemvelo.

5, izinga lokuncipha eliphansi, ukuzinza okuhle kwe-dimensional; I-Non-toxic, i-low density 6, ukumelana ne-dielectric kanye nokumelana nokukhanya kwe-PPO acid, i-alkali kanye ne-detergent nokunye ukugqwala okuyisisekelo, ngaphansi kwesimo sokucindezeleka, amafutha amaminerali kanye ne-ketone, i-ester solvents izokhiqiza ukuqhekeka kokucindezeleka; Izinyibilikisi zemvelo ezifana nama-aliphatic hydrocarbon, ama-halogenated aliphatic hydrocarbons nama-hydrocarbon anephunga elimnandi angancibilika futhi ancibilike.

Ubuthakathaka be-PPO ukumelana nokukhanya okubi, isikhathi eside ngaphansi kokukhanya kwelanga noma ukusetshenziswa kwesibani se-fluorescent kukhiqiza ukushintsha kombala, umbala ophuzi, isizathu siwukuthi ukukhanya kwe-ultraviolet kungenza iketango le-ether elimnandi lihlukane. Indlela yokuthuthukisa ukumelana nokukhanya kwe-PPO iba isihloko.

Ukusebenza kwe-PPO kunquma inkambu kanye nobubanzi besicelo:

①MPPO ukuminyana kuncane, kulula ukusetshenzwa, izinga lokushisa lokushintsha okushisayo ku-90-175℃, kukhona ukucaciswa okuhlukile kwezimpahla, ukuqina okuhle kwe-dimensional, kulungele ukwakhiwa kwemishini yasehhovisi, izinto zasendlini, amabhokisi ekhompyutha, i-chassis nezingxenye ezinembayo.

② I-MPPO dielectric engaguquki kanye nokulahlekelwa kwe-dielectric I-angle tangent kumapulasitiki obunjiniyela ayisihlanu aphansi kakhulu, okungukuthi, okokufaka okungcono kakhulu, nokumelana nokushisa okuhle, okufanele imboni kagesi. Ifanele ukwenza izingxenye zokuvikela kagesi, njengefreyimu yekhoyili, i-tube holder, i-shaft yokulawula, umkhono wesihlangu se-transformer, ibhokisi lokudlulisa, insika yokuvikela nokunye, okusetshenziselwa izimo ezimanzi nezilayishiwe.

③ I-MPPO inokumelana kahle namanzi nokumelana nokushisa, efaneleka ukwenza amamitha amanzi, amaphampu amanzi namashubhu entambo asetshenziswa ezimbonini zendwangu ezidinga izimpahla ezihlala isikhathi eside zabathengi ukuze kuphekwe. Amashubhu enziwe nge-MPPO anempilo ende yokusebenza.

④ I-dielectric constant kanye ne-dielectric loss loss I-angle tangent ye-MPPO ayithintwa izinga lokushisa nenombolo yomjikelezo kumapulasitiki wobunjiniyela, futhi inokumelana nokushisa okuhle nokuzinza kwe-dimensional, efanele imboni ye-elekthronikhi.
