1. Uea kila
I mea e hōʻoia ai i ke kaula hiki ke kū i ka nui axial tension i ka wā e kau ana a me ka noi ʻana, pono ke kaula i nā mea e hiki ai ke amo i ka ukana, metala, non-metal, i ka hoʻohana ʻana i ka uea kila ikaika kiʻekiʻe ma ke ʻano he mea hoʻoikaika, no laila. ʻO ke kaula he ʻaoʻao maikaʻi loa ke kūʻē ʻana i ke kaomi ʻaoʻao, ka hopena hopena, hoʻohana pū ʻia ke kaula kila no ke kaula ma waena o ka puʻu o loko a me ka puʻu o waho no ka mea kaua. E like me kona kalapona maʻiʻo hiki ke mahele i kiʻekiʻe kalapona kila uea a me ka haʻahaʻa kalapona kila uea.
(1) Uea kila kalapona kiʻekiʻe
Kiekie kalapona kila uea kila e hoʻokō i ka oaoieei koi o GB699 kiʻekiʻe-maikaʻi kalapona kila, ka maʻiʻo o ka sulfur a me ka phosphorus mea e pili ana i 0.03%, e like me kaʻokoʻa ili lapaʻau hiki ke maheleia i galvanized kila uea a phosphating kila uea. Pono ka uea kila galvanized i ka ʻāpana zinc e ʻaʻahu, paʻa, paʻa paʻa, maʻemaʻe ka ʻili o ka uea kila, ʻaʻohe aila, ʻaʻohe wai, ʻaʻohe stains; ʻO ka papa phosphating o ka phosphating uea e ʻaʻahu a ʻālohilohi, a ʻo ka ʻili o ka uea me ka ʻole o ka aila, ka wai, nā ʻōpala a me nā ʻeha. No ka mea liʻiliʻi ka nui o ka hydrogen evolution, ʻoi aku ka maʻamau o ka hoʻohana ʻana i ka uwea kila phosphating i kēia manawa.
(2) Uea kila kalapona haahaa
Hoʻohana maʻamau ka uea hao kalapona haʻahaʻa no ke kaula pale, pono e uhi ʻia ka ʻili o ke uea kila me kahi ʻāpana zinc a hoʻomau ʻia, ʻaʻole pono ka papa zinc i nā māwae, hōʻailona, ma hope o ka hoʻāʻo ʻana, ʻaʻohe manamana lima hiki ke holoi. ka māhā, lamination a hāʻule.
2. Ke kaula hao
Me ka hoʻomohala ʻana o ke kaula i ka helu kumu nui, piʻi ke kaumaha o ke kaula, a piʻi aʻe hoʻi ka haʻalulu e pono ai ka hoʻoikaika ʻana. I mea e hoʻomaikaʻi ai i ka hiki o ke kaula optical ke amo i ka ukana a me ka pale ʻana i ke koʻikoʻi axial i hiki ke hana ʻia i ka waiho ʻana a me ka hoʻohana ʻana i ke kaula uila, ʻo ke kaula kila e like me ka ʻāpana hoʻoikaika o ke kaula optical ka mea kūpono loa. loaʻa i kekahi maʻalahi. Hana ʻia ke kaula kila i nā kaula he nui o ka wili kila, e like me ka ʻāpana ʻāpana hiki ke hoʻokaʻawale ʻia i 1 × 3,1 × 7,1 × 19 ʻekolu ʻano. Hoʻohana maʻamau ka hoʻoikaika ʻana i ke kaula hao 1 × 7, ke kaula kila e like me ka ikaika tensile nominal i māhele ʻia i: 175, 1270, 1370, 1470 a me 1570MPa ʻelima mau māka, ʻoi aku ka nui o ka modulus elastic o ke kaula kila ma mua o 180GPa. ʻO ke kila i hoʻohanaʻia no ke kaula kila e pono e hoʻokō i nā koi o GB699 "Nā Kūlana Kūikawā no ka hoʻolālā kila kalapona kiʻekiʻe", aʻo kaʻili o ke kaula kila i hoʻohanaʻia no ke kaula kila e hoʻopaʻaʻia me kahiʻaʻahu a me ka papa mau o ka zinc, a ma laila. ʻAʻole pono nā kiko, nā māwae a me nā wahi me ka ʻole o ka zinc plating. ʻO ke anawaena a me ka mamao o ke kaula he ʻano like ʻole, ʻaʻole pono e wehe ʻia ma hope o ka ʻoki ʻana, a pono e hui pū ʻia ke kaula kila o ka uea strand, me ka ʻole o ka crisscross, fracture a me ka piko.
3.FRP
ʻO FRP ka pōkole o ka leka mua o ka plastic fiber English reinforced plastic, ʻo ia ka mea non-metallic me ka ʻili maʻemaʻe a me ke anawaena o waho i loaʻa ma ka uhi ʻana i ka ʻili o nā kaula aniani he nui me ka resin curing māmā, a pāʻani i ka hoʻoikaika ʻana. kuleana ma ka uwea optical. No ka mea, he mea hao ole ka FRP, loa'a ia ia na mea maikai e like me ka hooikaika ana me ka metala: (1) 'A'ole i ma'alahi nā mea metala 'ole i ka ha'alulu uila, a ua kūpono ke kaula uila no nā wahi uila; (2) ʻAʻole hoʻopuka ʻo FRP i ka hopena electrochemical me ka wai, ʻaʻole hana i nā kinoea ʻino a me nā mea ʻē aʻe, a kūpono i nā wahi ua, wela a me ka wai; (3) ʻaʻole ia e hoʻoulu i kēia manawa, hiki ke hoʻonohonoho ʻia ma ka laina kiʻekiʻe-voltage; (4) Loaʻa i ka FRP nā hiʻohiʻona o ke kaumaha māmā, hiki ke hoʻemi nui i ke kaumaha o ke kaula. Pono ka ʻili o ka FRP e maʻemaʻe, e liʻiliʻi ka poʻe ʻole, e like ke anawaena, a ʻaʻohe hui i ka lōʻihi o ka disc maʻamau.
4. Aramid
ʻO Aramid (polyp-benzoyl amide fiber) kahi ʻano fiber kūikawā me ka ikaika kiʻekiʻe a me ka modulus kiʻekiʻe. Hana ʻia ia mai ka p-aminobenzoic acid e like me ka monomer, ma ke alo o ka catalyst, i ka ʻōnaehana NMP-LiCl, e ka polymerization condensation solution, a laila ma ka wili pulu a me ka mālama wela kiʻekiʻe. I kēia manawa, ʻo nā huahana i hoʻohana ʻia ʻo ia ke kumu hoʻohālike huahana KEVLAR49 i hana ʻia e DuPont ma ʻAmelika Hui Pū ʻIa a me ke ʻano huahana Twaron i hana ʻia e Akzonobel ma Netherlands. Ma muli o kona kūpaʻa kiʻekiʻe kiʻekiʻe o ka wela a me ke kūpaʻa ʻana o ka thermal oxidation, hoʻohana ʻia ia i ka hana ʻana i ka hoʻoikaika ʻana i ke kelepona ʻokoʻa āpau āpau (ADSS).
5. Lilo puluniu aniani
ʻO ke aniani fiber yarn he mea metala ʻole i hoʻohana mau ʻia i ka hoʻoikaika ʻana i ke kaula optical, i hana ʻia me nā kaula aniani he nui. Loaʻa iā ia ka insulation maikaʻi loa a me ka pale ʻana i ka corrosion, a me ka ikaika tensile kiʻekiʻe a me ka haʻahaʻa haʻahaʻa haʻahaʻa, e kūpono ana ia no ka hoʻoikaika ʻana i ka non-metallic i nā kaula optical. Ke hoʻohālikelike ʻia me nā mea metala, ʻoi aku ka māmā o ke kaula aniani a ʻaʻole ia e hoʻoulu i kēia manawa, no laila kūpono loa ia no nā laina kiʻekiʻe-volt a me nā noi kelepona optical i nā wahi pulu. Eia kekahi, hōʻike ka wili aniani aniani i ke kūpaʻa maikaʻi a me ke kū ʻana o ka wā i ka hoʻohana ʻana, e hōʻoiaʻiʻo ana i ka paʻa lōʻihi o ke kaula i nā ʻano like ʻole.
