ʻO ka lining FRP kahi ala maʻamau a koʻikoʻi i ka hoʻokele corrosion i ka hana anti-corrosion kaumaha. Ma waena o lākou, hoʻohana nui ʻia ʻo FRP ma muli o kāna hana maʻalahi, ʻoluʻolu a me ka maʻalahi. Hiki ke ʻōlelo ʻia, ʻoi aku ka nui o ke kaʻina hana lima lima ma mua o 80% o ka hana anti-corrosion FRP. pākuʻi. ʻO ka "ʻekolu mau mea nui" resin, fiber a me ka pauka i loko o ka FRP i kau lima ʻia ka iwi o FRP, e kākoʻo ana i ka ikaika o ka ʻōnaehana FRP, a he mea nui ia o ka ʻike ʻana i ka hopena lōʻihi o ka anti-corrosion o FRP.
E like me ka ʻokoʻa o ke kaiapuni corrosive a me ka waena, e loli pū nā mea constituent o FRP. ʻO ke koho ʻana i nā mea waiwai i ka wā o ke kūkulu ʻana he kumu koʻikoʻi ia e hōʻoia ai e hiki ke hoʻololi i ka huahana FRP i hoʻopau ʻia i ke kaiapuni corrosive a me kona lōʻihi. No laila, pono e hoʻoholo i ke koho ʻana i nā mea hoʻoikaika FRP ma mua o ke kūkulu ʻana. ʻO kahi laʻana, ʻo nā mea hoʻoikaika i hōʻike ʻia e ka fiber aniani ka mea maʻamau o ka fiber, hiki ke pale i ka nui o ka ʻakika; akā naʻe,ʻaʻole lākou e kū'ē i ka waika hydrofluoric a me ka waika phosphoric wela. E hoʻohana i ka polyester, polypropylene a me nā lole fiber organic ʻē aʻe a me ka manaʻo, hiki iā ʻoe ke koho e hoʻohana i ka lole olonā a i ʻole degreased gauze, a ʻo kekahi mau huahana FRP pono i ka corrosion resistance a me ka conductivity, hiki iā ʻoe ke koho i nā mea kalapona. Ma kahi huaʻōlelo, ʻo ke koho ʻana i ka fiber i hoʻopaʻa ʻia i ka lima lima he mākaukau a me ka ʻike e pono ai ka ʻenehana anti-corrosion a me nā mea hoʻolālā.
I loko o nā huahana FRP i hoʻopili ʻia, ʻo ka hapa nui o nā fibers e hoʻoikaika nei i nā fibers aniani, inā he lole, manaʻo a ʻili paha. ʻO ke kumu nui ʻo ia ka hoʻohui ʻana i ke kumu kūʻai, loaʻa iā ia nā hiʻohiʻona maikaʻi loa:
01 Ke kūʻē kemika
ʻAʻole e pala, ʻeleʻele a ʻeʻe paha nā ʻili lole fiberglass nonorganic. Kūʻē lākou i ka nui o nā waikawa koe wale ka hydrofluoric a me ka waika phosphoric wela.
02 Paʻa paʻa
ʻAʻole kikoo a emi ʻole nā kaula aniani aniani i hoʻohana ʻia no ka hana ʻana i nā lole aniani ma muli o nā loli i ke ʻano o ka lewa. ʻO ka elongation nominal i ka wā hoʻomaha he 3-4%. He 5.4 × 10-6 cm/cm/°C ka awelika linear thermal expansion coefficient o ka bulk E-aniani.
03 Hana wela maikaʻi
ʻO nā lole Fiberglass ka haʻahaʻa haʻahaʻa o ka hoʻonui ʻana i ka wela a me ka conductivity thermal kiʻekiʻe. Hoʻopau wikiwiki ʻo Fiberglass i ka wela ma mua o ka asbestos a i ʻole nā mea kūlohelohe.
04 Ka ikaika tensile kiʻekiʻe
He kiʻekiʻe ka ikaika-a-kaumaha o ka wili fiberglass. ʻOi aku ka ikaika o ka paona o ke kaula fiberglass ma mua o ka uwea kila. ʻO ka hiki ke hana i ka ikaika unidirectional a bidirectional paha i loko o ka lole e hoʻonui nui i ka maʻalahi o nā huahana hoʻohana hope.
05 Kūleʻa wela kiʻekiʻe
ʻAʻole ʻā ʻia nā kīʻaha aniani inorganic a pale ʻole i ka wela kiʻekiʻe a mālama i nā mahana i ʻike pinepine ʻia i ka hana ʻoihana. E mālama ka Fiberglass ma kahi o 50% o kona ikaika ma 700°F a me 25% ma 1000°F.
06 Haʻahaʻa hygroscopicity
Hana ʻia nā wili fiberglass me nā fibers porous ʻole a no laila he haʻahaʻa haʻahaʻa loa.
07 ʻO ka hoʻopili uila maikaʻi
ʻO ka ikaika dielectric kiʻekiʻe a me ka mau dielectric haʻahaʻa haʻahaʻa, me ka haʻahaʻa haʻahaʻa o ka wai a me ke kūpaʻa wela kiʻekiʻe, e hana i nā lole fiberglass maikaʻi loa no ka insulation uila.
08 Hiki ke hoʻololi i ka huahana
ʻO nā filament maikaʻi loa i hoʻohana ʻia i nā wili fiberglass, nā ʻano nui a me nā hoʻonohonoho hoʻonohonoho, nā ʻano ulana like ʻole, a me nā hoʻopau kūikawā he nui nā lole fiberglass e pono ai no ka nui o nā hoʻohana hope ʻoihana.
09 kumu kūʻai haʻahaʻa
Hiki i nā lole Fiberglass ke hana i ka hana a ua like ke kumukūʻai me nā lole synthetic a me nā lole fiber maoli.
No laila, ʻo ka fiber aniani kahi mea hoʻoikaika lima FRP hoʻopaʻa lima, ʻoi aku ka waiwai, maʻalahi a maʻalahi hoʻi e hana. ʻO ia kekahi o nā mea i hoʻohana nui ʻia ma waena o nā mea hoʻoikaika i kēia manawa.
