I-matrix ye-resin yezinhlanganisela ze-thermoplastic ihilela amapulasitiki obunjiniyela ajwayelekile futhi akhethekile, futhi i-PPS ingummeleli ojwayelekile wamapulasitiki wobunjiniyela akhethekile, ngokuvamile aziwa ngokuthi "igolide lepulasitiki".Izinzuzo zokusebenza zifaka izici ezilandelayo: ukumelana nokushisa okuhle kakhulu, izakhiwo ezinhle zemishini, ukumelana nokugqwala, nokuzishisa kuze kufike ku-UL94 V-0.Ngenxa yokuthi i-PPS inezinzuzo zokusebenza ezingenhla, futhi uma iqhathaniswa namanye amapulasitiki wobunjiniyela be-thermoplastic asebenza kahle kakhulu, inezici zokucubungula kalula nezindleko eziphansi, ngakho isibe yi-resin matrix enhle kakhulu yokukhiqiza izinto eziyinhlanganisela.

I-PPS plus short glass fiber (SGF) composite material inezinzuzo zamandla aphezulu, ukumelana nokushisa okuphezulu, i-flame retardant, ukucubungula kalula, izindleko eziphansi, njll.
I-PPS lengthened glass fiber (LGF) composite material inezinzuzo zokuqina okuphezulu, i-warpage ephansi, ukumelana nokukhathala, ukubukeka okuhle komkhiqizo, njll. Ingasetshenziselwa ama-impellers, ama-pump casings, amalunga, ama-valve, ama-chemical pump impellers nama-casings, amanzi okupholisa. ama-impeller namaShell, izingxenye zikagesi zasendlini, njll.

Ngakho-ke yimuphi umehluko othize ezimpahleni ze-fiber glass fiber (SGF) kanye ne-long glass fiber (LGF) izinhlanganisela ze-PPS eziqinisiwe?

Izakhiwo eziphelele zezinhlanganisela ze-PPS/SGF (i-fiber yengilazi emfushane) nezinhlanganisela ze-PPS/LGF (i-glass fiber ende) ziye zaqhathaniswa.Isizathu sokuthi kungani inqubo yokuncibilika kokuncibilika isetshenziswa ekulungiseleleni i-screw granulation ukuthi ukufakwa kwe-fiber bundle kuyabonakala ekubunjweni kokufakwa, futhi i-fiber ayilimazi.Okokugcina, ngokuqhathaniswa kwedatha yezakhiwo eziwumshini zokubili, inganikeza ukwesekwa kobuchwepheshe kubasebenzi besayensi nezobuchwepheshe ohlangothini lwesicelo lapho kukhethwa izinto zokusebenza.

Ukuhlaziywa kwempahla yemishini
Imicu eqinisayo eyengezwe ku-resin matrix ingakha uhlaka lwamathambo olusekelayo.Lapho izinto ezihlanganisiwe zingaphansi kwamandla angaphandle, imicu yokuqinisa ingathwala ngempumelelo indima yemithwalo yangaphandle;ngesikhathi esifanayo, ingakwazi ukumunca amandla ngokuphuka, ukuguqulwa, njll., futhi ithuthukise izakhiwo zemishini ye-resin.

Lapho okuqukethwe kwe-fiber yengilazi kwanda, imicu yengilazi eyengeziwe entweni eyinhlanganisela ingaphansi kwamandla angaphandle.Ngesikhathi esifanayo, ngenxa yokwanda kwenani lemicu yengilazi, i-resin matrix phakathi kwemicu yengilazi iba mncane, okwenza kube ngcono kakhulu ekwakhiweni kwamafreyimu aqinisiwe we-glass fibre;ngakho-ke, ukwanda kokuqukethwe kwe-fiber yengilazi kwenza izinto ezihlanganisiwe zidlulise ukucindezeleka okwengeziwe kusuka ku-resin kuya ku-fiber yengilazi ngaphansi komthwalo wangaphandle, okuthuthukisa ngokuphumelelayo izakhiwo eziqinile nokugoba zezinto ezihlanganisiwe.
Izici eziqinile neziguquguqukayo zezinhlanganisela ze-PPS/LGF ziphakeme kunezinhlanganisela ze-PPS/SGF.Uma ingxenye enkulu yefiber yengilazi ingu-30%, amandla e-tensile we-PPS/SGF nezinhlanganisela ze-PPS/LGF yi-110MPa kanye ne-122MPa, ngokulandelana;Amandla e-flexural yi-175MPa kanye ne-208MPa, ngokulandelanayo;i-flexural elastic moduli yi-8GPa ne-9GPa, ngokulandelana.
Amandla aqinile, amandla aguquguqukayo kanye ne-flexural elastic modulus yezinhlanganisela ze-PPS/LGF zanda ngo-11.0%, 18.9% no-11.3%, ngokulandelana, uma kuqhathaniswa nezinhlanganisela ze-PPS/SGF.Izinga lokugcinwa kobude be-glass fiber ku-PPS/LGF composite material liphezulu.Ngaphansi kokuqukethwe kwe-fiber yengilazi efanayo, into eyinhlanganisela inokumelana nomthwalo okuqinile kanye nezakhiwo ezingcono zokusebenza.
