Amapulasitiki wobunjiniyela asebenza kahle kakhulu-PPO polyphenylene ether material.Ukumelana nokushisa okuhle kakhulu, izakhiwo zikagesi, amandla aphezulu kanye nokumelana nokukhuphuka nokunye, kunikeza izinto ze-PPO ngezinzuzo zohlelo lokusebenza ezimotweni., izinto zikagesi, i-5G nezinye izinkambu.
Ngenxa ye-viscosity ephezulu yokuncibilika kanye nokungabi namanzi kahle kwezinto ze-PPO, izinto ze-PPO ezilungisiwe (MPPO) okwamanje zisemakethe, futhi izinto eziguquliwe ze-PPO alloy ziyindlela ebaluleke kakhulu yokuguqula.
Okulandelayo yizinto ezijwayelekile eziguquliwe ze-PPO emakethe, ake sibheke:
01.PPO/PA ingxubevange impahla
Impahla ye-PA (inayiloni) inezici ezinhle kakhulu zemishini, ukumelana nokugqoka, ukuzigcoba, ukucubungula kalula nezinye izici, kodwa ukumuncwa kwamanzi asezindaweni ezishisayo kukhulu kakhulu, futhi ubukhulu bomkhiqizo bushintsha kakhulu ngemva kokumuncwa kwamanzi.
Impahla ye-PPO inokumuncwa okuphansi kakhulu kwamanzi, ukuqina okuhle kobukhulu, kanye nokumelana okuhle kakhulu nokukhasa, kodwa ukucutshungulwa okungekuhle.Kungashiwo ukuthi i-PPO/PA alloy material ihlanganisa izici ezinhle kakhulu zalokhu okubili.Le nto ye-alloy nayo iwuhlobo lwe-alloy olukhula ngokushesha kanye nezinhlobonhlobo eziningi phakathi kwama-PPO alloys.Isetshenziselwa ikakhulukazi izingxenye zezimoto, njengezimbozo zamasondo, izingxenye ze-peripheral injini, njll.
Kufanele kuqashelwe ukuthi i-amorphous PPO kanye ne-crystalline PA azihambisani ne-thermodynamically, futhi imikhiqizo yazo elula yokuhlanganisa kulula ukuyiqeda, inezinto ezimbi zemishini, futhi inenani eliphansi elisebenzayo;izinyathelo ezifanele kumele zithathwe ukwenza ngcono ukusebenza kwalokhu okubili.ukuhambisana ukuze kuthuthukiswe ukusebenza kwayo.Ukwengeza into ehambisanayo efanele kanye nokwamukela inqubo efanelekile kungathuthukisa ngempumelelo ukuhambisana kwe-PPO ne-PA.
02.I-PPO/HIPS ingxubevange yezinto
Impahla ye-PPO inokuhambisana okuhle nempahla ye-polystyrene, futhi ingaxutshwa kunoma iyiphi ingxenye ngaphandle kokunciphisa izakhiwo zemishini kakhulu.
Ukwengezwa kwe-HIPS kokubalulekile kwe-PPO kukhulisa amandla omthelela anonqatshiwe.Ngokuvamile, ukuze kuthuthukiswe amandla omthelela wesistimu futhi kuthuthukiswe ukusebenza kukonke, ama-elastomer avame ukungezwa njengezilungisi eziqinisayo, njenge-SBS, i-SEBS, njll.
Ngaphezu kwalokho, i-PPO ngokwayo iwuhlobo lwe-polymer evimbela amalangabi, kulula ukwenza ikhabhoni, futhi enezici zokuzicisha ngokwazo.Uma kuqhathaniswa nama-HIPS ahlanzekile, izakhiwo ezingavimbeli ilangabi ze-PPO/HIPS alloys nazo zingathuthukiswa kakhulu.Ngokukhula kwenani le-PPO, ukuncibilika kokuconsa kanye nokubhema kwengxube ye-polymer ngesikhathi sokusha kwehla kancane kancane, futhi izinga lokuvutha elivundlile lakhula kancane kancane.
Izinkambu ezisetshenziswa kakhulu: izingxenye zezimoto ezimelana nokushisa, amathuluzi kagesi nemishini kagesi, izingxenye zemishini yokuvala inzalo yesitimu, njll.
03.PPO/PP ingxubevange impahla
Intengo nokusebenza kwama-alloys e-PPO/PP kuphakathi kwalawo amapulasitiki obunjiniyela, njenge-PA, i-ABS, i-fiber yengilazi ende PP, i-PET eshintshiwe ne-PBT, njll., futhi bathole izinga eliphakeme lokuqina, ukuqina, ukumelana nokushisa kanye intengo.ibhalansi enhle.Izicelo zisembonini yezimoto, amandla, amabhokisi amathuluzi, amathreyi okuphatha ukudla, izingxenye zokuthutha uketshezi (izindlu zamaphampu), njll.
Ama-alloys athandwa ngabakhi bezimoto ngenxa yokuhambisana kwawo namanye amapulasitiki ngesikhathi sokugaywa kabusha, okungukuthi angahlanganiswa futhi agaywe kabusha namanye amapulasitiki asekelwe ku-PP noma uhla lwamapulasitiki asekelwe ku-polystyrene.
04.I-PPO/PBT ingxubevange yezinto
Nakuba izinto ze-PBT zinezakhiwo ezinhle eziphelele, kusekhona izinkinga ezifana ne-hydrolysis elula, ukungakwazi ukumelana namanzi ashisayo isikhathi eside, imikhiqizo ethambekele ku-anisotropy, ukuncipha kokubumba kanye ne-warpage, njll. Ukuguqulwa kwe-alloy ngezinto ze-PPO kungathuthukisana ngokuphumelelayo.amaphutha okusebenza.
Ngokocwaningo lwento ehlobene ye-alloy, i-viscosity ephansi ye-PPO impahla ifaneleka kakhulu ukuxutshwa ne-PBT material alloy, kodwa futhi idinga i-compatibilizer ukuze ihambisane.
Okuvame ukusetshenziselwa ukwenza izinto zikagesi, izingxenye zemishini kagesi nokunye.
05. PPO/ABS ingxubevange impahla
Impahla ye-ABS iqukethe isakhiwo se-PS, esinokuhambisana kahle ne-PPO futhi singahlanganiswa ngokuqondile.Izinto ze-ABS zingathuthukisa kakhulu amandla omthelela we-PPO, zithuthukise ukuqhekeka kwengcindezi, futhi zinikeze i-PPO electroplatability, kuyilapho igcina ezinye izici eziphelele ze-PPO.
Intengo ye-ABS iphansi kunaleyo ye-PPO, futhi izinsiza zemakethe ziningi.Ngenxa yokuthi lezi zinto ezimbili ziyahambisana futhi inqubo yokuhlanganisa ilula, kungashiwo ukuthi iyingxubevange ye-PPO yenhloso evamile, elungele izingxenye zezimoto, izinto zegobolondo zokuvikela i-electromagnetic, izinto zasehhovisi, imishini yasehhovisi kanye namashubhu okuphotha, njll.
