He aha ke aniani fiber reinforced plastic?
ʻO nā plastic fiber reinforced glass he ʻano like ʻole o nā mea hoʻohui me nā waiwai like ʻole a me nā noi ākea.He mea hana hou ia i hana ʻia me ka resin synthetic afiberglass composite material ma o ka hana hui.
ʻO nā hiʻohiʻona o ke aniani fiber reinforced plastics:
（1）ʻO ke kūpaʻa ʻino maikaʻi: ʻO ka FRP kahi mea pale-corrosion maikaʻi.He kū'ē maikaʻi kona i ka lewa;ka wai a me ka nui o ka waikawa a me ka alkali;ka paʻakai, nā ʻaila like ʻole a me nā mea hoʻoheheʻe, a ua hoʻohana nui ʻia i ka anti-corrosion kemika.o na ano a pau.Ke pani nei ia i ke kila kalapona;kila kohu ʻole;lāʻau;nā metala non-ferrous a me nā mea ʻē aʻe.
(2) ʻO ke kaumaha māmā a me ka ikaika kiʻekiʻe: ʻO ka mānoanoa pili o FRP ma waena o 1.5 a me 2.0, ʻo ia wale nō ka 1/4 a hiki i ka 1/5 o ke kila kalapona, akā kokoke ka ikaika tensile a ʻoi aku paha ma mua o ke kalapona. kila, a hiki ke hoʻohālikelike ʻia ka ikaika me ke kila kila kila., hoʻohana nui ʻia i ka aerospace;nā pahu kiʻekiʻe a me nā huahana ʻē aʻe e pono e hoʻemi i ko lākou kaumaha ponoʻī.
(3) Nā waiwai uila maikaʻi: ʻO FRP kahi mea hoʻokalakupua maikaʻi loa, hoʻohana ʻia e hana i nā insulators, a hiki ke mālama i ka hana maikaʻi ma nā alapine kiʻekiʻe.
(4) Maikaʻi thermal hana: FRP he haʻahaʻa uila conductivity, 1.25 ~ 1.67KJ ma lumi wela, wale 1/100 ~ 1/1000 metala mea he maikai loa thermal insulation mea.He kūpono no ka pale wela a me ke kū'ē ablation ma lalo o nā kūlana wela kiʻekiʻe.
(5) Hana maikaʻi loa: hiki ke koho ʻia ke kaʻina hana e like me ke ʻano o ka huahana, a maʻalahi ke kaʻina hana a hiki ke hoʻoheheʻe ʻia i ka manawa hoʻokahi.
(6) Hoʻolālā maikaʻi: hiki ke koho piha ʻia nā mea e like me nā pono e hoʻokō i nā koi o ka hana huahana a me ke ʻano.
(7) ʻO ka modulus elastic haʻahaʻa: ʻO ka modulus elastic o FRP he 2 manawa nui ma mua o ka lāʻau akā he 10 mau manawa liʻiliʻi ma mua o ke kila, no laila ua manaʻo pinepine ʻia ʻaʻole lawa ka rigidity i ka hoʻolālā huahana a ua maʻalahi ka deformed.Hiki ke hana ʻia ka hoʻonā i loko o kahi ʻano pūpū lahilahi;Hiki ke hana ʻia ke ʻano hana sandwich ma ke ʻano o nā fiber modulus kiʻekiʻe a i ʻole e hoʻoikaika i nā iwi ʻaoʻao.
(8) ʻAʻole hiki ke hoʻohana ʻia ka FRP no ka manawa lōʻihi ma ke kiʻekiʻe wela, a ʻo ka ikaika o ka FRP o ka resin polyester kumu nui e emi nui i ka wā ma luna o 50 degere.
(9) ʻO keʻano o kaʻelemakule: ma lalo o ka hana a nā kukui ultraviolet;makani, one, ua a me ka hau;mea hoʻopāpā kemika;mechanical stress, etc., he maʻalahi ke kumu o ka hoʻohaʻahaʻa hana.
(10) Haʻahaʻa haʻahaʻa haʻahaʻa haʻahaʻa haʻahaʻa haʻahaʻa: ʻO ka ikaika ʻoki interlaminar e lawe ʻia e ka resin, no laila haʻahaʻa.Hiki ke hoʻomaikaʻi ʻia ka adhesion interlayer ma ke koho ʻana i kahi kaʻina hana, me ka hoʻohana ʻana i kahi mea hoʻohui, a me nā mea ʻē aʻe, a e hoʻāʻo e pale i ka ʻoki ʻana i ka interlayer i ka wā hoʻolālā huahana.
ʻO nā pōmaikaʻi o nā plastic fiber reinforced glass:
ʻOi aku ka kiʻekiʻe o ka wela wela o nā pulu aniani i hoʻoikaika ʻia ma mua o kēlā me ka ʻole o ke aniani aniani, ʻoi aku ka nui o nā plastic nylon.
ʻO nā plastic fiber i hoʻoikaika ʻia he haʻahaʻa haʻahaʻa a me ka rigidity kiʻekiʻe.
Ke aniani puluniu i hoʻoikaika 'ia ka plastic 'aʻole stress māwae, a me ka hopena kū'ē ofemoglas fibra de vidio ʻoi aku ka maikaʻi o ka plastic
He kiʻekiʻe ka ikaika o nā plastic fiber glass reinforced, e like me: ka ikaika tensile, ka ikaika compressive, ka ikaika kulou, kiʻekiʻe loa nā mea a pau.
Ma muli o ka hoʻohui ʻana i nā mea hoʻohui ʻē aʻe,fiber glasua ho'emi nui nā plastic i ho'oikaika 'ia i ka hana kuni 'ana o nā plastic fiber glass reinforced plastics, a 'a'ole hiki ke ho'ā 'ia ka hapa nui o nā mea, no laila he mea pale ahi.
ʻO nā hemahema o nā plastic fiber glass reinforced:
Ma muli o ka hoʻohui ʻana oe aniani fiber, ua lilo ke aniani fiber reinforced plastic i opaque, a ua akaka ma mua o ka hoʻohui ʻana i ka fiber aniani.
ʻO ka plastic aniani fiber reinforced plastic he haʻahaʻa haʻahaʻa a hoʻonui i ka brittleness ma mua o ka plastic me ka ʻole aniani;
Ma muli o ka hoʻohui ʻana o ka fiber aniani, hoʻonui ka viscosity hehee o nā mea āpau, lilo ka wai i mea ʻilihune, a ʻoi aku ka kiʻekiʻe o ke kaomi injection ma mua o ka ʻole o ka fiber aniani.No ka hoʻoheheʻe ʻana maʻamau, ʻoi aku ka kiʻekiʻe o ka mahana injection o nā plastic i hoʻoikaika ʻia ma mua o kēlā me ka hoʻohui ʻole ʻana i ka fiber aniani.Ua hoʻokiʻekiʻe mua ʻia ka fiber aniani e 10 ℃ -30 ℃.
Ma muli o ka hoʻohui o ke aniani fiber a me nā mea hoʻohui, nā waiwai hygroscopic odaw fiberglass Hoʻonui nui ʻia nā plastic i hoʻoikaika ʻia.ʻO nā plastik maʻemaʻe maoli ʻaʻole e hoʻomoʻi i ka wai e lilo pū kekahi.No laila, pono e hoʻomaloʻo ʻia i ka wā o ka hoʻoheheʻe ʻana.
I ka wā o ke kaʻina hana hoʻoheheʻe ʻia o ke aniani fiber i hoʻoikaika ʻia i ka plastic, hiki i ke aniani ke komo i ka ʻili o ka huahana plastik, e hoʻolilo i ka ʻili o ka huahana a ʻeleʻele loa.I mea e hoʻokō ai i ke ʻano kiʻekiʻe o ka ʻili, hoʻohana ʻia ka mīkini wela wela e wela i ka ʻōpala i ka wā o ka hoʻoheheʻe ʻana, i komo ka polymer plastic i ka ʻili o ka huahana, akā ʻaʻole hiki ke hoʻokō ʻia ke ʻano hiʻohiʻona o ka plastic maʻemaʻe.
Ma hope o ka hoʻoikaika ʻia ʻana o ka fiber aniani,e aniani aniani he mea me ka paakiki kiekie.Ma hope o ka hoʻoheheʻe ʻia ʻana o ka mea hoʻohui i ka wela kiʻekiʻe, he kinoea corrosive loa ia, ka mea e hoʻoulu ai i ka ʻaʻahu nui a me ka corrosion i ka wili a me ka hoʻoheheʻe ʻia o ka mīkini hoʻoheheʻe injection.No laila, hoʻohana ʻia kēia ʻano mea i ka hana ʻana.I ka hoʻohana ʻana i nā mīkini a me nā mīkini hoʻoheheʻe injection, e hoʻolohe i ka mālama anti-corrosion ili a me ka mālama ʻana i ka paʻakikī o nā mea hana.
Hoʻoikaika i ka hopena o ka fiber aniani ma ka nylon
ʻO Nylon, i kapa ʻia ʻo polyamide, he mea synthetic me ka nui o nā noi, i hoʻohana ʻia i nā textiles, packaging, nā ʻāpana mechanical a me nā māla ʻē aʻe.
Ma ke ʻano he plastic engineering, aia ka PA66 i ka nui o nā pūʻulu hydrophilic amide, e kaupalena ana i kāna kahua noi.Hoʻohana maʻamau ia i ka ʻoihana e hoʻololi iā ia ma o ka copolymerization, ka hui ʻana i ka paʻakikī, a me ka hoʻoikaika ʻana.
ʻO ka hoʻoikaika ʻana i ka fiber Glass kahi ʻano hoʻololi maʻamau.Hiki iā ia ke hoʻoikaika maikaʻi i ke kūpaʻa ʻaʻahu, ka ikaika, ka paʻakikī a me ke kūpaʻa dimensional o ka nylon.
Hana ʻia ke aniani fiber me ka pyrophyllite, ke one quartz, ka limestone a me nā minerale ʻē aʻe ma o ke kiʻi ʻana i ka wela kiʻekiʻe, kiʻi uea, wili, ulana a me nā hana ʻē aʻe, a ʻo kona anawaena monofilament e pili ana i kahi mau microns.
Ke kumu o ka hoʻoikaika ʻana i ka fiber aniani: ʻEkolu ala no ka fiber e hoʻopaʻa ai i ka ikaika o ka hopena: ka haki ʻana o ka fiber, ka huki ʻana o ka fiber, a me ka haki resin.Ke piʻi aʻe ka lōʻihi o ka fiber, ʻoi aku ka ikaika o ka huki ʻana o ka fiber, i mea e pono ai ka hoʻomaikaʻi ʻana i ka ikaika hopena.
PA66 / aniani fiber composite mea haʻahaʻa wai absorption, kiʻekiʻe kiko'ī ikaika a me ka kemikala kū'ē, a me kona mau huahana i maikai moisture absorption kū'ē, dimensional paʻa, kiʻekiʻe ikaika, paakiki, a me ka hana hana, no laila, ua hoʻohana nui 'ia i loko o nā kaʻaahi, machinery, automotive. , nā mea uila a me nā kahua ʻē aʻe.
ʻO ka lōʻihi omea aniani uila modulus elasticʻO ka maʻamau i hoʻohana ʻia e hoʻoikaika i ka nylon ma kahi o 3mm a 12mm.Ke piʻi aʻe ka lōʻihi o ka fiber, piʻi ka hopena i ka hoʻoikaika kino.Maikaʻi ma kahi o 12mm.
ʻO ka maʻamau, ka lōʻihi ofilament fiberglasshe 12mm, a me ka loa okīʻaha aniani ʻokiʻokihe 3mm.Ke hoʻohālikelike ʻia me ka fiber aniani pōkole, ʻo ka hiʻohiʻona kupaianaha o ka hoʻoikaika ʻana i ka fiber glass lōʻihi ʻo ia ka pālua o ka ikaika o ka hopena.Eia kekahi, loaʻa nā pono o ka ikaika kiʻekiʻe, rigidity kiʻekiʻe, kiʻekiʻe notched hopena ikaika, pōkole ka wela wela a me ka luhi luhi maikaʻi, a hiki ke mālama i nā waiwai mechanical maikaʻi i ke kiʻekiʻe kiʻekiʻe a me ka haʻahaʻa haʻahaʻa., hiki ke hoʻohana ʻia ma ke ʻano he mea hana ma kahi o ka metala.
