He aha nā pono hana maʻamau o FRTP?

ʻO nā mea hoʻohui wela i hoʻopaʻa ʻia i ka fiber (FRTP)

 

Nā mea hoʻohui thermoplastic i hoʻopaʻa ʻia i ka fiber he ʻāpana koʻikoʻi o nā mea hoʻohuihui. Hoʻoikaika ʻia nā resins thermoplastic like ʻolekīʻaha aniani(GF),kalapona kalapona (CF), aramid fibers (AF) a me nā mea fiber ʻē aʻe. Loaʻa nā waiwai maikaʻi o nā mea hoʻohui thermoplastic fiber-reinforced e like me ke kiʻekiʻe o ka paʻakikī, ka pale ʻana i ka corrosion a me ka pale ʻana i ka luhi, ke kaʻina hana maʻalahi, pōkole pōkole, kiʻekiʻe o ka hoʻohana ʻana i nā mea waiwai (ʻaʻohe ʻōpala), ʻaʻohe pono no ka mālama haʻahaʻa haʻahaʻa, a ua lilo i noiʻi. piko pele ma ka ʻoihana waiwai.

 

Nā pōmaikaʻi hana maʻamau o FRTP

 

Ua hoʻohana ʻia ka Thermoplastic composite FRTP no nā makahiki. Hoʻohālikelike ʻia me nā mea hoʻohui thermosetting e like me ka resin phenolic, ka resin urea-formaldehyde, ka resin epoxy, a me ka polyurethane, loaʻa i nā composites thermoplastic kekahi mau waiwai kūikawā:

 

◆Haʻahaʻa haʻahaʻa a me ka ikaika kiʻekiʻe:ʻO ka mānoanoa o FRTP he 1.1-1.6g/cm3, ʻo ia wale nō ka 1/5-1/7 o ke kila, 1/3-1/4 māmā ma mua o ka thermosetting FRP, a hiki ke loaʻa me kahi ʻāpana liʻiliʻi ʻoi aku ka ikaika mechanical a papa noi.

 

◆Nui o ke kūʻokoʻa i ka hoʻolālā hana: Hoʻolālā ʻia nā waiwai kino, nā waiwai kemika, a me nā waiwai mechanical o FRTP ma o ke koho kūpono ʻana o nā ʻano mea maka, ka like ʻana, nā ʻano hana, ka ʻike fiber a me nā ʻano layup. He nui nā mea, nā mea nui loa he polyetherketoneketone (PEKK), polyetherketone (PEEK), polyphenylene sulfide (PPS), nylon (PA), polyetherimide (PEI), etc. No laila, kona ʻO ke degere o ke kūʻokoʻa i ke koho ʻana a me ka hoʻolālā. ʻoi aku ka nui.

 

◆Nā waiwai wela: ʻO ka mahana hoʻohana maʻamau o ka plastic he 50-100 ℃, a hiki ke hoʻonui ʻia i luna o 100 ℃ ma hope o ka hoʻoikaika ʻia ʻana me ke aniani aniani. ʻO ka wela wela o ka PA6 he 65 ° C, a ma hope o ka hoʻoikaika ʻana me 30% aniani fiber, hiki ke hoʻonui ʻia ka mahana distortion wela i 190 ° C. ʻO ka pale wela o PEEK a hiki i 220 ° C. Ma hope o ka hoʻoikaika ʻana me 30% aniani fiber, hiki ke hoʻonui ʻia ka mahana hana i 310 ° C. ʻAʻole hiki ke hoʻokō ʻia nā mea hoʻohui thermosetting e like me ke kūpaʻa wela kiʻekiʻe.

 

◆Ke kūʻiʻo kino kino: Hoʻoholo nui ʻia e ka hana o ka mea matrix. Nui nā ʻano resins thermoplastic, a loaʻa i kēlā me kēia resin kona mau ʻano anti-corrosion ponoʻī. No laila, hiki ke koho ʻia ka resin matrix e like me ke ʻano hoʻohana a me nā kūlana waena o ka mea hoʻohui. ʻO ka maʻamau, hiki ke hoʻokō i nā koi o ka hoʻohana. ʻOi aku ka maikaʻi o ka pale wai o FRTP ma mua o nā mea hoʻohui thermosetting.

 

◆Nā waiwai uila: Loaʻa i ka FRTP nā waiwai dielectric maikaʻi, ʻaʻole hōʻike i nā hawewe lekiō, a hoʻouna maikaʻi i nā microwaves. No ka mea, ʻoi aku ka liʻiliʻi o ka hoʻoheheʻe wai o FRTP ma mua o ka FRP thermosetting, ʻoi aku ka maikaʻi o kāna mau mea uila ma mua o ka hope. Ma hope o ka hoʻohui ʻana i nā mea conductive i ka FRTP, hiki iā ia ke hoʻomaikaʻi i kona conductivity a pale i ka hana ʻana o ka uila static.

 

◆Hiki ke hana hou ʻia ka ʻōpala: Hiki ke hana hou ʻia ka FRTP a hana ʻia, hiki ke hana hou ʻia nā ʻōpala a me nā koena, a ʻaʻole loli nui nā waiwai kino a me nā mīkini, ʻaʻole ia e hoʻohaumia i ke kaiapuni. koi kaiapuni.
