Iyo resin matrix yeiyo thermplastic marobhoti inosanganisira maPurasitiki emaginiya, uye pps imiriri yakajairika yePlansering Eplastices, inowanzozivikanwa se "goridhe" rinowanzozivikanwa ". Zvekuita zvakanakira zvinosanganisira zvinotevera zvikamu: zvakanakisa kupisa kupokana, zvakanaka michina zvimiro, kupesana, uye kuzvishingisa kusvika kuUL94 V-0 level. Nekuti pps ine zviyero zviri pamusoro apa, uye zvichienzaniswa nedzimwe yakakwirira-pesvedzero yeinjiniya yeinjiniya yekugadzirisa, iyo yakaderera mutengo, saka zvave zvakanaka resin matrix yezvinhu zvekugadzira zvinyorwa.

PPS Plus pfupi yegirazi fiber (SGF) zvinyorwa zvine zvakanakira simba rakanyanya, rakanyanya kupisa kupokana, murazvo unodzoreredza, zviri nyore kugadzirisa, mutengo wakaderera, nezvimwe.
Pps yakawedzera girazi fiber (LGF) zvinyorwa zvine zvakanakira kuomeswa kwakanyanya, kutaridzika kwakadzika, macomputer pombi.

Saka ndezvipi chaizvo kusiyana kwezvivakwa zvepfupi girazi fiber (sgf) uye refu girazi fiber (LGF) yakasimbiswa PPS compositite?

Zvimiro zvakazara zvePPS / SGF (pfupi girazi fiber) composites uye pps / LGF (LGF (LEGRORE FIBETISE FIBER) DZIDZO YAKAITWA. Chikonzero nei chinyungudike chekushandiswa zvinoshandiswa mukugadziriswa kwescrew granulation ndeyekuti iyo fiber bundle inozoonekwa mukusaziva, uye fiber haina kukuvara. Pakupedzisira, kuburikidza nekuenzanisa kwedata kweiyo mechancal zvivakwa zvevaviri, zvinogona kupa rutsigiro rwehunyanzvi rweanoshanda-side resainzi uye technological vashandi kana vakasarudza zvinhu.

Mechancal Property Ongororo
Iyo inosimbisa fibers yakawedzerwa mune resin matrix inogona kuumba iyo inotsigira skeleton. Kana izvo zvinyorwa zvemavara zvichiratidzwa kune simba rekunze, iyo inosimbisa machira inogona kutakura zvinobudirira basa remitoro yekunze; Panguva imwecheteyo, inogona kutora simba kuburikidza nekupwanya, deformc., uye kugadzirisa maitiro emuchina weiyo resin.

Kana iyo girazi fiber zvemukati inowedzera, mamwe magetsi egirazi muzvinyorwa zvemukati zvinoiswa pasi pemasimba ekunze. Panguva imwecheteyo, nekuda kwekuwedzera kwehuwandu hwemagetsi egirazi, iyo resin matrix pakati pegirazi frabers dzinova dzakaonda, iro rinogona kuita mukuvakwa kwegiramu rakasimbiswa. Naizvozvo, kuwedzera kwegirazi fiber zvemukati kunoita kuti zvinhu zvinyararire kutamisa kushushikana kubva kune iyo resin kune girazi fiber pasi pemutoro wekunze, izvo zvinokonzera zvinokonzeresa uye zvichikweretesa zvinhu zvezvinyorwa zvemukati.
Iyo Tensile uye Inoshanduka Zvivakwa zvePPS / LGF makombuta yakakwira kupfuura iyo yePPS / SGF manyadzo. Kana chikamu chakawanda chegirazi fiber ndeye 30%, iyo tensile simba rePPS / SGF uye PPS / LGF makombuta ndeye 110mpa uye 122mpa, zvichiteerana; Simba rinoslippuro ndeye 175mpa uye 208mpa, zvichiteerana; Iyo inoshanduka elastic moduli is 8GPA uye 9GPA, zvichiteerana.
Simba reSimba, rinoshanduka-shanduka uye dzinoshurika elastic modulus yePPS yakawedzerwa ne 11.0%, 18,9% uye ne 11.3%, tichienzanisa nePPS / SGF manyoro. Kureba kwehurefu hwemagetsi egirazi muPPS / LGF YEMAHARA YEMAHARA. Pasi peiyo imwechete yegirazi fiber yezvinyorwa, zvinyorwa zvemhando yepamusoro zvine simba rekuramba kuramba uye zviri nani michina manhamba.
