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 resin "ʻekolu mau mea nui" resin, fiber a me ka pauka i loko o ka FRP lima lima ka iwi o FRP, e kākoʻo ana i ka ikaika o ka pūnaewele FRP, a he mea nui ia o kaʻikeʻana 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 i ka 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 waika;akā naʻe, ʻaʻole lākou e kūʻē i ka waika hydrofluoric a me ka corrosion 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 o ka FRP i hoʻopaʻa ʻia i ka 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 kū'ē 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 Kiʻekiʻe tensile ikaika
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 Hoʻololi 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.
