I-resin matrix yama-plastitis we-thermoplastic ifaka amapulasithi ajwayelekile futhi akhethekile wobunjiniyela, futhi i-PPS ingummeleli ojwayelekile wepulasitiki wobunjiniyela obukhethekile, owaziwa ngokuthi "igolide lepulasitiki". Izinzuzo zokusebenza zifaka phakathi kwalezi zinto ezilandelayo: Ukumelana kahle nokushisa okuhle, izakhiwo ezinhle zemishini, ukumelana nokugqwala, nokuzenzela ukuzilahla kuze kube se-UL94 V-0. 0 Izinga. Ngoba i-PPS inezinzuzo zokusebenza okungenhla, futhi iqhathaniswa namanye amapulasitiki wobunjiniyela obuphezulu be-thermoplastic, inezimpawu zokucubungula okulula nezindleko eziphansi, ngakho-ke sekuyinto eyakhiwe kahle ye-resin yokukhiqiza izinto zokwakha.

I-PPS Plus Glass Fiber Fiber (SGF) Izinto ezihlanganisiwe zinezinzuzo zamandla aphezulu, ukumelana nokushisa okuphezulu, i-flame retardant, ukucubungula okulula, izindleko eziphansi, njll.
I-PPS ebekelwe i-fiber fiber (LGF) izinto ezihlanganisiwe zinezinzuzo zobunzima obuphakeme, ukumelana kwempi ephansi, ukumelana nomkhiqizo okuhle, ama-valves, ama-valves, izingxenye zamanzi ezipholile, izingxenye zensiza zasekhaya, njll.

Ngakho-ke yini umehluko othize kwizakhiwo ze-fiber yengilazi emfushane (SGF) kanye ne-Lide Glass Fiber Fiber Fiber (LGF) Izihlanganisi ze-PPS eziqinisiwe?

Izakhiwo eziphelele ze-PPS / SGF (I-Short Glass Fiberfu) Ama-Composites kanye ne-PPS / LGF (ama-composites amade) aqhathaniswa. Isizathu esenza ukuthi inqubo yokufakwa kokuncibilika isetshenziswa lapho kulungiswa i-Screw Granution ukuthi ukukhishwa kwe-fiber bundle kutholwe ekubumbeni okugciniwe, futhi i-fiber ayonakaliswa. Ekugcineni, ngokuqhathaniswa kwedatha yempahla yemishini yalezi ezimbili, kunganikeza ukwesekwa kwezobuchwepheshe kwabasebenzi besayensi kanye nezobuchwepheshe lapho ukhetha izinto zokwakha.

Ukuhlaziywa Kwezakhiwo Zomshini
Imicu yokuqinisa angezwe ku-resin matrix ingakha umthambo oxhasayo. Lapho impahla eyinhlanganisela ibhekiswe amandla angaphandle, imicu yokuqinisa ingathwala indima yemithwalo yangaphandle; Ngasikhathi sinye, kungadonsa amandla ngokuqhekeka, ukuguquguquka, njll., futhi kuthuthukise izakhiwo zemishini ze-resin.

Lapho okuqukethwe kwengilazi kwengilazi kukhuphuka, imicu eminingi yengilazi ezintweni ezihlanganisiwe zibhekwa emandleni angaphandle. Ngasikhathi sinye, ngenxa yokwanda kwenombolo yemicu yengilazi, i-resin matrix phakathi kwemicu yengilazi iba mncane, okulungele ukwakhiwa kohlaka oluqinisiwe lwengilazi; Ngakho-ke, ukwanda kokuqukethwe kwengilazi yeglass kunika amandla impahla eyinhlanganisela ukudlulisa ingcindezi ethe xaxa kusuka ku-resin kuya ku-fiber yangaphandle, okuthuthukisa ngempumelelo izakhiwo ezixakile nokugoba kwezinto ezihlanganisiwe.
Izakhiwo ezishukumisayo neziguqukayo zama-composites e-PPS / LGF aphezulu kunalezo ze-PPS / SGF Composites. Lapho ingxenye enkulu yengilazi yengilazi ingama-30%, amandla ashubile e-PPS / SGF nama-PPS / LGF ahlanganisiwe angama-110MPA angama-110MPA angama-120MA, ngokulandelana; Amandla aguqukayo angama-175mpa kanye no-208MPA, ngokulandelana; I-Flemral elastic moduliyi yi-8GPA ne-9GPA, ngokulandelana.
Amandla ashukumisayo, amandla aguqukayo kanye ne-modulus ye-flemral elastic yama-composites e-PPS / LGF anyuswe ngo-11.0%, ngo-18,9% no-11.3%, ngokulandelana, ngokuqhathaniswa nezinhlanganisela ze-PPS / SGF. Izinga lokugcinwa kobude befayibha yengilazi kwizinto ezibonakalayo ze-PPS / LGF ziphezulu. Ngaphansi kokuqukethwe kwe-fiber efanayo efanayo, impahla eyinhlanganisela inokumelana nomthwalo oqinile kanye nezakhiwo ezingcono zemishini.
