Matrix ye resin yema thermoplastic composites inosanganisira mapurasitiki akajairika neeinjiniya, uye PPS inomiririra mapurasitiki einjiniya akasarudzika, anowanzozivikanwa se "goridhe repurasitiki". Zvakanakira mashandiro azvo zvinosanganisira zvinotevera: kudzivirira kupisa kwakanyanya, hunhu hwakanaka hwemakanika, kudzivirira ngura, uye kuzvipisa kusvika padanho reUL94 V-0. Nekuti PPS ine zvakanakira mashandiro ataurwa pamusoro apa, uye kana ichienzaniswa nemamwe mapurasitiki einjiniya ethermoplastic anoshanda zvakanyanya, ine hunhu hwekugadziriswa kuri nyore uye mutengo wakaderera, saka yave matrix yakanaka ye resin yekugadzira zvinhu zvakasanganiswa.

Zvinhu zvakagadzirwa nePPS pamwe neshinda pfupi yegirazi (SGF) zvine zvakanakira zvekuti zvine simba guru, hazvipise kupisa zvakanyanya, zvinodzivisa moto, zviri nyore kugadzira, zvinodhura zvishoma, nezvimwewo.
Zvinhu zvakagadzirwa nePPS lengthened glass fiber (LGF) zvine mabhenefiti ekuti zvakasimba, hazvina kusimba zvakanyanya, hazvina kuneta, zvinotaridzika zvakanaka, nezvimwewo. Zvinogona kushandiswa kuma impellers, mapombi casings, majoints, mavalvu, makemikari pump impellers nema casings, ma impellers emvura inotonhorera nemaShells, zvikamu zvemidziyo yepamba, nezvimwewo.

Saka ndeapi musiyano chaiwo uripo pakati pezvinhu zvema "short glass fiber" (SGF) ne "long glass fiber" (LGF) zvakasimbiswa nePPS composites?

Hunhu hwakazara hwePPS/SGF (short glass fiber) composites uye PPS/LGF (long glass fiber) composites hwakaenzaniswa. Chikonzero nei nzira yekunyungudutsa impregnation ichishandiswa pakugadzirira screw granulation ndechekuti impregnation yefiber bundle inowanikwa mu impregnation mold, uye fiber haikuvadzi. Chekupedzisira, kuburikidza nekuenzanisa data rehunhu hwemakanika hweviri ava, inogona kupa rutsigiro rwehunyanzvi kune vashandi vesainzi netekinoroji vari pakusarudza zvinhu.

Kuongorora zvivakwa zvemakanika
Mashinda ekusimbisa anowedzerwa mu resin matrix anogona kuumba skeleton inotsigira. Kana zvinhu zvakasanganiswa zvikashandiswa nesimba rekunze, mashinda ekusimbisa anogona kutakura basa remitoro yekunze; panguva imwe chete, anogona kutora simba kuburikidza nekutyoka, kushanduka, nezvimwewo, uye kuvandudza hunhu hwemuchina we resin.

Kana huwandu hwefiber yegirazi hukawedzera, fiber yegirazi yakawanda iri muzvinhu zvakasanganiswa inobatwa nemasimba ekunze. Panguva imwe chete, nekuda kwekuwedzera kwehuwandu hwefiber yegirazi, resin matrix iri pakati pefiber yegirazi inova yakatetepa, izvo zvinoita kuti zvive nyore kuvaka maframe akasimbiswa nefiber yegirazi; saka, kuwedzera kwehuwandu hwefiber yegirazi kunobvumira zvinhu zvakasanganiswa kutamisa kushushikana kwakawanda kubva kuresini kuenda kufiber yegirazi pasi pemutoro wekunze, izvo zvinovandudza zvinobudirira hunhu hwekudhonza nekukombama kwezvinhu zvakasanganiswa.
Hunhu hwekudhonza nekuchinjika hwePPS/LGF composites hwakakwira kupfuura hwePPS/SGF composites. Kana chikamu chikuru chegirazi fiber chiri 30%, simba rekudhonza rePPS/SGF nePPS/LGF composites riri 110MPa ne122MPa, zvichiteerana; Simba rekudhonza ndiro 175MPa ne208MPa, zvichiteerana; flexural elastic moduli ndeye 8GPa ne9GPa, zvichiteerana.
Simba rekudhonza, simba rekudhonza uye modulus yekudhonza yePPS/LGF composites yakawedzerwa ne11.0%, 18.9% uye 11.3%, zvichiteerana, zvichienzaniswa nePPS/SGF composites. Mwero wekuchengetedza urefu hwegirazi fiber muPPS/LGF composite material wakakwira. Pasi pehuwandu hwegirazi fiber hwakafanana, jira rekudhonza rine simba rakasimba rekudzivirira mutoro uye hunhu huri nani hwemakanika.
