ʻO ka matrix resin o nā composites thermoplastic e pili ana i nā plastics ʻenekinia laulā a me nā mea kūikawā, a ʻo PPS kahi ʻelele maʻamau o nā plastics ʻenekinia kūikawā, i ʻike nui ʻia ʻo "plastic gold". ʻO nā pono hana e pili ana i kēia mau ʻano: ke kūpaʻa wela maikaʻi loa, nā waiwai mechanical maikaʻi, ke kūpaʻa i ka corrosion, a me ka lapalapa ponoʻī a hiki i ka pae UL94 V-0. No ka mea, loaʻa iā PPS nā pono hana i luna, a hoʻohālikelike ʻia me nā plastics ʻenekinia thermoplastic hana kiʻekiʻe ʻē aʻe, loaʻa iā ia nā ʻano o ka hana maʻalahi a me ke kumukūʻai haʻahaʻa, no laila ua lilo ia i matrix resin maikaʻi loa no ka hana ʻana i nā mea composite.

Loaʻa i ka mea hui PPS me ke aniani pōkole (SGF) nā pono o ka ikaika kiʻekiʻe, ke kūpaʻa wela kiʻekiʻe, ka pale ahi, ka maʻalahi o ka hana ʻana, ke kumukūʻai haʻahaʻa, a pēlā aku.
Loaʻa i ka mea hui PPS hoʻolōʻihi ʻia ke aniani fiber (LGF) nā pono o ke kiʻekiʻe o ka paʻakikī, ka haʻahaʻa o ke kaua ʻana, ke kūpaʻa i ka luhi, ke ʻano maikaʻi o ka huahana, a pēlā aku. Hiki ke hoʻohana ʻia no nā impellers, nā pahu pamu, nā hui, nā valves, nā impellers a me nā pahu pamu kemika, nā impellers wai hoʻoluʻu a me nā pūpū, nā ʻāpana mīkini home, a pēlā aku.

No laila he aha nā ʻokoʻa kikoʻī i nā waiwai o nā fiber aniani pōkole (SGF) a me nā composites PPS i hoʻoikaika ʻia i ka fiber aniani lōʻihi (LGF)?

Ua hoʻohālikelike ʻia nā waiwai piha o nā hui PPS/SGF (poloka aniani pōkole) a me nā hui PPS/LGF (poloka aniani lōʻihi). ʻO ke kumu e hoʻohana ʻia ai ke kaʻina hana impregnation hoʻoheheʻe i ka hoʻomākaukau ʻana o ka granulation screw, ʻo ia ka hoʻokō ʻia ʻana o ka impregnation o ka pūʻolo fiber i loko o ka ʻōmole impregnation, a ʻaʻole i hōʻino ʻia ka fiber. ʻO ka mea hope loa, ma o ka hoʻohālikelike ʻikepili o nā waiwai mechanical o nā mea ʻelua, hiki iā ia ke hāʻawi i ke kākoʻo loea no nā limahana ʻepekema a me nā ʻenehana ʻaoʻao noi i ke koho ʻana i nā mea.

Ka loiloi waiwai mīkini
Hiki i nā olonā hoʻoikaika i hoʻohui ʻia i loko o ka matrix resin ke hana i kahi iwi kākoʻo. Ke kau ʻia ka mea i hui pū ʻia i ka ikaika o waho, hiki i nā olonā hoʻoikaika ke halihali pono i ke kuleana o nā ukana o waho; i ka manawa like, hiki iā ia ke omo i ka ikehu ma o ka haki, deformation, a me nā mea ʻē aʻe, a hoʻomaikaʻi i nā waiwai mechanical o ka resin.

Ke piʻi aʻe ka nui o ke aniani o ke kaula aniani, ʻoi aku ka nui o nā aniani o ke kaula aniani i loko o ka mea i hui pū ʻia i nā mana o waho. I ka manawa like, ma muli o ka piʻi ʻana o ka nui o nā aniani o ke kaula aniani, ua lahilahi ka matrix resin ma waena o nā aniani o ke kaula aniani, ʻoi aku ka maikaʻi o ke kūkulu ʻana i nā mōlina i hoʻoikaika ʻia me ke kaula aniani; no laila, ʻo ka hoʻonui ʻia ʻana o ka nui o ke kaula aniani e hiki ai i ka mea i hui pū ʻia ke hoʻoili i ke kaumaha hou aʻe mai ka resin i ke kaula aniani ma lalo o ke kaumaha o waho, kahi e hoʻomaikaʻi pono ai i nā waiwai tensile a me ke kūlou o ka mea i hui pū ʻia.
ʻOi aku ke kiʻekiʻe o nā waiwai tensile a me flexural o nā composites PPS/LGF ma mua o nā composites PPS/SGF. Ke 30% ka hapa nui o ke kaula aniani, ʻo ka ikaika tensile o nā composites PPS/SGF a me PPS/LGF he 110MPa a me 122MPa, kēlā me kēia; ʻO ka ikaika flexural he 175MPa a me 208MPa, kēlā me kēia; ʻo nā moduli elastic flexural he 8GPa a me 9GPa, kēlā me kēia.
Ua hoʻonui ʻia ka ikaika tensile, ka ikaika flexural a me ka modulus elastic flexural o nā composites PPS/LGF e 11.0%, 18.9% a me 11.3%, kēlā me kēia, i hoʻohālikelike ʻia me nā composites PPS/SGF. ʻOi aku ke kiʻekiʻe o ka helu paʻa lōʻihi o ka fiber aniani i loko o ka mea composite PPS/LGF. Ma lalo o ka nui o ka fiber aniani like, ʻoi aku ka ikaika o ka pale ʻana i ka ukana a me nā waiwai mechanical maikaʻi.
