ʻO ka resin matrix o ka thermoplastic composites e pili ana i nā plastic engineering maʻamau a kūikawā, a ʻo ka PPS kahi mākaʻikaʻi maʻamau o nā plastic engineering kūikawā, i kapa ʻia ʻo "plastic gula".ʻO nā mea maikaʻi o ka hana e pili ana i kēia mau hiʻohiʻona: ʻoi aku ka maikaʻi o ka wela, nā waiwai mechanical maikaʻi, ke kū ʻana o ka corrosion, a me ka hiki ke puhi ʻia a hiki i ka pae UL94 V-0.No ka mea, loaʻa iā PPS nā pono hana ma luna, a hoʻohālikelike ʻia me nā plastics ʻenehana thermoplastic kiʻekiʻe, loaʻa iā ia nā hiʻohiʻona o ka hana maʻalahi a me ke kumu kūʻai haʻahaʻa, no laila ua lilo ia i matrix resin maikaʻi loa no ka hana ʻana i nā mea composite.

PPS me ka pōkole aniani fiber (SGF) composite mea i nā pono o ka ikaika kiʻekiʻe, kiʻekiʻe wela kū'ē, flame retardant, hana maʻalahi, haʻahaʻa kumu kūʻai, etc.
PPS lōʻihi aniani puluniu (LGF) composite mea i ka pono o kiʻekiʻe toughness, haʻahaʻa warpage, luhi kū'ē, maikaʻi huahana helehelena, etc. Hiki ke hoʻohana 'ia no ka impellers, pump casings, ami, kiwikā, kemikala pauma impellers a me casings, wai hooluolu. nā impellers a me nā Shells, nā ʻāpana mea hana hale, etc.

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

Hoʻohālikelike ʻia nā waiwai piha o ka PPS/SGF (puʻu aniani pōkole) a me ka PPS/LGF (lōʻihi aniani lōʻihi) composites.ʻO ke kumu i hoʻohana ʻia ai ke kaʻina hoʻoheheʻe impregnation i ka hoʻomākaukau ʻana i ka granulation screw i ʻike ʻia ka impregnation o ka pūpū fiber i loko o ka impregnation mold, a ʻaʻole i hōʻino ʻia ka fiber.ʻO ka hope, ma o ka hoʻohālikelike ʻikepili o nā waiwai mechanical o nā mea ʻelua, hiki iā ia ke hāʻawi i ke kākoʻo ʻenehana no ka ʻaoʻao noiʻi ʻepekema a me nā limahana ʻenehana i ke koho ʻana i nā mea.

Hiki i nā mea hoʻoikaika ikaika i hoʻohui ʻia i loko o ka resin matrix ke hana i kahi iwi kākoʻo.Ke hoʻokau ʻia ka mea composite i ka ikaika o waho, hiki i nā fibers hoʻoikaika ke hoʻokō pono i ka hana o nā ukana o waho;i ka manawa like, hiki iā ia ke komo i ka ikehu ma o ka haʻihaʻi, deformation, etc., a hoʻomaikaʻi i nā waiwai mechanical o ka resin.

Ke piʻi aʻe ka maʻiʻo aniani, ʻoi aku ka nui o nā aniani i loko o ka mea i hui pū ʻia i nā mana o waho.I ka manawa like, ma muli o ka hoʻonui ʻana i ka nui o nā aniani aniani, ʻoi aku ka lahilahi o ka resin matrix ma waena o nā aniani aniani, ʻoi aku ka maikaʻi o ke kūkulu ʻana i nā pā aniani i hoʻoikaika ʻia;no laila, ʻo ka hoʻonui ʻana i ka ʻike aniani fiber hiki ke hoʻololi i ke koʻikoʻi mai ka resin a i ka fiber aniani ma lalo o ka ukana o waho, kahi e hoʻomaikaʻi maikaʻi ai i nā waiwai tensile a me ke kulou ʻana o ka mea hoʻohui.
ʻOi aku ka kiʻekiʻe o nā waiwai tensile a me ka flexural o ka PPS/LGF composites ma mua o ka PPS/SGF composites.Ke 30% ka hakina nui o ke aniani aniani, he 110MPa a me 122MPa ka ikaika tensile o PPS/SGF a me PPS/LGF composites;ʻO nā ikaika flexural he 175MPa a me 208MPa;ʻO ka flexural elastic moduli he 8GPa a me 9GPa.
Ua hoʻonuiʻia ka ikaika tensile, ka ikaika flexural a me ka modulus elastic elastic o ka PPS / LGF composites e 11.0%, 18.9% a me 11.3%, i hoʻohālikelikeʻia me ka PPS / SGF composites.ʻOi aku ka kiʻekiʻe o ka lōʻihi o ka mālama ʻana o ka fiber aniani i ka PPS/LGF composite material.Ma lalo o ke aniani fiber maʻiʻo like, ʻoi aku ka ikaika o ka hoʻouka ʻana o ka mea composite a ʻoi aku ka maikaʻi o nā waiwai mechanical.
