Iyo resin matrix ye thermoplastic composite inosanganisira akajairwa uye akakosha einjiniya mapurasitiki, uye PPS mumiriri weakakosha einjiniya mapurasitiki, anowanzozivikanwa se "goridhe repurasitiki".Mabhenefiti ekuita anosanganisira anotevera maficha: yakanakisa kupisa kupisa, yakanaka michina zvivakwa, corrosion resistance, uye kuzvipisa kusvika paUL94 V-0 level.Nekuti PPS ine zvakanakira kuita zviri pamusoro, uye zvichienzaniswa nemamwe mapurasitiki einjiniya epamusoro-soro, ine hunhu hwekugadzirisa zviri nyore uye mutengo wakaderera, saka yave yakanakisa resin matrix yekugadzira zvinhu zvinosanganiswa.

长-短玻纤

PPS plus short glass fiber (SGF) composite material ine zvakanakira simba rakawanda, high heat resistance, flame retardant, easy processing, low cost, etc.
PPS yakarebesa girazi faibha (LGF) composite material ine zvakanakira kusimba kwakanyanya, yakaderera warpage, kuneta kuramba, yakanaka chigadzirwa chitarisiko, etc. Inogona kushandiswa impellers, pombi casings, majoini, mavharuvhu, kemikari pombi impellers uye casings, inotonhorera mvura. ma impellers uye Shells, midziyo yemumba, nezvimwe.

Saka ndeipi misiyano chaiyo mumidziyo yepfupi girazi fiber (SGF) uye refu girazi fiber (LGF) yakasimbiswa PPS macomposites?

Iyo yakazara zvimiro zvePPS/SGF (ipfupi girazi fiber) composites uye PPS/LGF (yakareba girazi fiber) maumbirwo akaenzaniswa.Chikonzero nei iyo yakanyunguduka impregnation process inoshandiswa mukugadzirira kwescrew granulation ndeyekuti iyo impregnation yefiber bundle inoitwa mu impregnation mold, uye fiber haina kukuvara.Chekupedzisira, kuburikidza nekuenzanisa kwedata kweiyo mechaniki zvivakwa zvevaviri, inogona kupa rutsigiro rwehunyanzvi kune yekushandisa-parutivi vashandi vesainzi uye tekinoroji pakusarudza zvinhu.

Mechanical property analysis
Iyo yekusimbisa fiber yakawedzerwa mune resin matrix inogona kugadzira skeleton inotsigira.Kana iyo yakasanganiswa inoiswa pasi pesimba rekunze, iyo inosimbisa fibers inogona zvinobudirira kutakura basa rekunze mitoro;panguva imwecheteyo, inogona kutora simba kuburikidza nekutsemuka, deformation, nezvimwewo, uye inovandudza michina ye resin.

Kana iyo girazi fiber yemukati inowedzera, yakawanda girazi fibers mune inoumbwa zvinhu inoiswa pasi pemasimba ekunze.Panguva imwecheteyo, nekuda kwekuwedzera kwenhamba yegirazi fibers, resin matrix pakati pegirazi fibers inova yakaonda, iyo inonyanya kubatsira pakuvakwa kwegirazi fiber reinforced frames;saka, kuwedzera kwegirazi fiber content inogonesa iyo inoumbwa zvinhu kuendesa zvakanyanya kushushikana kubva kune resin kusvika kune girazi fiber pasi pemutoro wekunze, izvo zvinonyatso kuvandudza kusimba uye kubhenda zvimiro zvezvakaumbwa zvinhu.
Iwo anotenha uye anochinjika zvimiro zvePPS/LGF macomposites akakwira kupfuura ayo ePPS/SGF anosanganisa.Kana chikamu chikuru chegirasi fiber chiri 30%, simba rekusimba rePPS/SGF uye PPS/LGF composites i110MPa uye 122MPa, zvichiteerana;Iwo masimba ekuchinja ari 175MPa uye 208MPa, zvichiteerana;iyo flexural elastic moduli ndeye 8GPa uye 9GPa, zvichiteerana.
Kusimba kwesimba, kushanduka kwesimba uye flexural elastic modulus yePPS / LGF composites yakawedzerwa ne11.0%, 18.9% uye 11.3%, maererano, zvichienzaniswa nePPS / SGF composites.Hurefu hwekuchengeta mwero wegirazi fiber muPPS/LGF inoumbwa zvinhu yakakwira.Pasi peiyo yakafanana girazi fiber yemukati, iyo inoumbwa zvinhu ine yakasimba kuroja kuramba uye zvirinani zvemuchina.
