ʻO nā mea i hoʻololi hou ʻia: Glass Fiber Reinforced Modified Phenolic Resin (FX-501)

Phenolic Kinohi aniani, ma waena o nā resins synthetic mua loa, he polycondensate maʻamau i hana ʻia e ka polymerization o nā phenols a me nā aldehydes i mua o kahi catalyst alkaline. Hoʻokomo ʻia kekahi mau mea hoʻohui e hoʻohui i ke ʻano macromolecular, e hoʻololi iā ia i kahi ʻano macromolecular insoluble a infusible ʻekolu-dimensional, a laila lilo ia i mea maʻamau. mea polimer thermosetting. Manaʻo nui ʻia nā resins Phenolic no kā lākou mau waiwai koʻikoʻi, me ka hoʻopaneʻe ahi maikaʻi loa, ke kūpaʻa dimensional, a me ka ikaika mechanical maikaʻi. Ua hoʻoikaika kēia mau ʻano i ka noiʻi nui a me ka hoʻohana ʻana i nā mea resin fiber glass phenolic.

Ke holomua nei nā ʻoihana ʻoihana, hoʻonui ʻia nā koi i ka hana o ka phenolic Kinohi Kinohi Meas. No laila,kiʻekiʻe-ikaika a me ka wela hoololiia phenolic fibers anianike kūkulu ʻia nei a hoʻohana nui ʻia. Ua hoʻoikaika ʻia ka pulupulu aniani i hoʻololi ʻia (FX-501)i kēia manawa kekahi o nā mea hoʻololi hou ʻia phenolic fiber resin material. He ʻano hou ia o nā mea phenolic i hoʻololi ʻia a hoʻoikaika ʻia i hana ʻia e ka hoʻopili ʻana i nā fibers aniani i loko o ka matrix resin kumu ma o ka hui ʻana.

Nā Waiwai Mechanical a me nā kuleana kumu

Phenolic aniani fiber resinkoho pinepine ʻia ma ke ʻano he matrix no ʻaʻahu-pale, tensile, a compressive meama muli o kona ikaika tensile maikaʻi, ka pale ʻana i ka solvent, a me nā waiwai mechanical maikaʻi loa e like me ke ahi retardancy. ʻO ka mea matrixhana mua ma ke ʻano he mea hoʻopaʻa, hoʻopili kino i nā ʻāpana āpau. Nā pulu anianie lawelawe ma ke ano he mau mea lawe ukana nui i na mea aahu, e haawi ana i ka hiki ke amo, a o ka lakou hana maikai e pili pono ana i ka hopena hooikaika ma ka matrix.

ʻO ke kuleana o ka mea matrix ka hoʻopaʻa paʻa ʻana i nā mea ʻē aʻe o ka mea tensile, e hōʻoia i ka hoʻoili like ʻana o nā ukana, puʻunaue ʻia, a hoʻokaʻawale ʻia i nā ʻāpana aniani like ʻole. Hāʻawi kēia i kahi ikaika a paʻakikī i ka mea. ʻO nā pulupulu maʻamau, me nā fiber aniani, nā fiber organik, Kino kilas, a me ka mineral fibers, pāʻani i ka hana i ka hoʻoponopono ʻana i ka ikaika tensile o ka mea.

Kaumaha i loko o nā Composites a me ka hopena o ka maʻiʻo fiber

In phenolic fiber composite material system, na mea elua ʻO nā pulupulu a me ka resin matrix e amo i ka ukana, me nā pulu aniani e waiho ana i ka mea lawe ukana mua. Ke hoʻokau ʻia nā phenolic fiber composites i ke kulou a i ʻole ke koʻikoʻi koʻikoʻi, ua hoʻoneʻe ʻia ke koʻikoʻi mai ka resin matrix i nā fibers aniani pākahi ma o ke kikowaena, e hoʻopuehu maikaʻi i ka ikaika i lawe ʻia. ʻO kēia kaʻina hana e hoʻomaikaʻi i nā ʻano mechanical o ka mea hoʻohui. No laila, he hoʻonui kūpono i hiki ke hoʻonui i ka ikaika o nā pulu aniani phenolic fiber composites.

Hōʻike nā hopena hoʻokolohua i kēia mau mea:

• Phenolic fiber composites me 20% aniani fiber contenthōʻike i ka hāʻawi ʻole ʻana o ka fiber, me kekahi mau wahi i nele i ka fiber.
• Phenolic fiber composites me 50% aniani fiber contenthōʻike i ka hāʻawi like ʻana o ka fiber, nā ʻili haki ʻole, a ʻaʻohe hōʻailona koʻikoʻi o ka huki ʻana i waho. Hōʻike kēia e hiki i nā pulu aniani ke amo pū i ka ukana, ka hopena ʻoi aku ka ikaika flexural.
• Ke 70% ka nui o ke aniani fiber, ʻo ka nui o ka fiber e alakaʻi i kahi matrix resin haʻahaʻa haʻahaʻa. Hiki i kēia ke hana i nā hanana "resin-poor" i kekahi mau wahi, ke keʻakeʻa nei i ka neʻe ʻana o ke kaumaha a me ka hoʻokumu ʻana i nā koʻikoʻi koʻikoʻi kūloko. No laila, ʻo nā waiwai mechanical āpau o ka phenolic glass fiber composite material e emi iho.

Mai kēia mau ʻike, ʻo ka ʻO ka hoʻohui kiʻekiʻe loa i ʻae ʻia o ke aniani aniani i nā phenolic fiber composites he 50%.

Hoʻonui i ka hana a me nā mea hoʻoikaika

Mai ka ʻikepili helu, phenolic aniani puluniu composites i loaʻa 50% aniani puluniuhōʻike ma kahi o ʻekolu manawa o ka ikaika flexurala ʻehā manawa o ka ikaika compressivehoʻohālikelike ʻia me ka resin phenolic maʻemaʻe. Hoʻohui ʻia, ʻo nā mea ʻē aʻe e pili ana i ka ikaika o ka phenolic glass fiber reinforced plastics me ka ka lōʻihi o nā pulu aniania me kā lākou hoʻonohonoho ʻana.
