ʻO ka fiberglass reinforcement, i kapa ʻia hoʻi ʻo GFRP reinforcement, he ʻano hou o ka mea hoʻohui.ʻAʻole maopopo ka poʻe he aha ka ʻokoʻa ma waena o ia me ka hoʻoikaika kila maʻamau, a no ke aha mākou e hoʻohana ai i ka fiberglass reinforcement?E hōʻike ana ka ʻatikala aʻe i nā pono a me nā hemahema o ka fiberglass reinforcement a me ke kila maʻamau, a ma hope o ka hoʻohālikelike ʻana, e ʻike inā hiki i ka fiberglass reinforcement ke pani i ke kila maʻamau?

He ahapulupuluanianimea hoʻoikaika
Ma ke ʻano he mea hana hou kiʻekiʻe, hoʻohana nui ʻia ka fiberglass reinforcement i nā alaloa subway (pale), nā alaloa, nā alahaka, nā mokulele, nā pahu, nā kikowaena, nā papahana mālama wai, nā papahana lalo a me nā māla ʻē aʻe, a hiki ke hoʻololi i nā wahi corrosive e like me ka wai. nā mea kanu lapaʻau, nā mea kanu kemika, nā pahu electrolytic, nā uhi manhole, nā papahana pale kai.Hiki i ka Fiberglass hoʻoikaika ke hoʻoponopono i nā pilikia he nui i ka ʻenekinia, hoʻoponopono i nā hemahema o ke kila kuʻuna, a lawe mai i nā manawa hoʻomohala hou i ka ʻenekinia kīwila a me ke kūkulu hale.

ʻO nā mea maikaʻi a me nā pōʻino o ke kila maʻamau apulupuluanianihoʻoikaika
1, kiʻekiʻe haʻahaʻa haʻahaʻa, kiʻekiʻe tensile ikaika, ka ikaika o ka pahu he palua ka nui o ke anawaena rebar, aka, o ke kaumaha he 1/4 wale no o ka pahu kila;
2、ʻano elastic paʻa, ma kahi o 1/3 ~ 2/5 o ka pahu kila;
3、Electrical a me ka wela insulation, thermal hoʻonui coefficient ua kokoke i ka sima ma mua o ke kila;
4、ʻoi aku ka maikaʻi o ka corrosion, kūpono no ka hoʻohana ʻana i ka wai a i ʻole nā ​​​​mea ʻino ʻē aʻe e like me ka mālama wai, nā alahaka, nā pahu a me nā tunnels;
5, haʻahaʻa ka ikaika shear, ʻo ka ikaika o ka fiberglass reinforcement shear ikaika wale nō ʻo 50 ~ 60MPa he mau waiwai ʻoki maikaʻi loa.

I ka hana a me ke kila ma ke ano like, a he maikai ka adhesion, aka, he ikaika tensile kiʻekiʻe a me ka ikaika ʻāhi haʻahaʻa, hiki ke ʻoki pololei ʻia e ka mīkini pale composite, me ka ʻole o ka hōʻino ʻana i nā mea hana.

ʻO ka ʻokoʻa ma waena o ka fiberglass reinforcement a me ka hoʻoikaika kila
1, ma ke ʻano o ka manawa hana, ke hoʻohālikelike ʻia i nā kaola kila maʻamau, hoʻopili ʻia ka fiberglass reinforcement e ka mea hana, no ka mea ʻaʻole hiki ke hoʻoponopono ʻia ka pūnaewele, no laila pono e hoʻomalu pono ʻia ka nui, i ka manawa e alakaʻi ai ka mea hewa i ka lohi i ka manawa hana. .Hoʻopili pololei ʻia kona ʻano, e hōʻemi ana i nā kaʻina hana o nā kaola kila maʻamau, a ʻo ke ʻano o ka hoʻopaʻa ʻana e pani i ke kaʻina hana kuʻi, mālama i ka manawa hana o ka hale pa.
2、Ma ke ʻano o ka paʻakikī o ke kūkulu ʻana, ʻokoʻa loa ke kuʻekuʻe ʻana a me ka ʻoki ʻana o ka fiberglass reinforcement i nā kaola kila maʻamau a ʻoi aku ka māmā o ka maikaʻi, no laila ʻoi aku ka paʻa ma mua o ka hale kila maʻamau i ke kaʻina o ka hoʻokiʻekiʻe ʻana i ka hale, ka hoʻohaʻahaʻa i ka hale a ʻO ka ninini ʻana, maʻalahi ke ʻike ʻia i ka hale hoʻoheheʻe, ka hoʻopaʻa ʻana i ka hīnaʻi, ka lana ʻana a me nā kūlana kūikawā ʻē aʻe, pono ka nānā kūikawā i ka hana ʻana a me ka hāpai ʻana.
3、Ma ke ʻano o ka palekana o ke kūkulu ʻana, ke hoʻohālikelike ʻia me ke ʻano hana o ka ʻāpana a i ʻole ka haki ʻana i ka pā mau o ka hale hoʻoikaika i ka pale pale, hiki ke komo pololei ʻia ka pā mau o ka hale fiberglass e ka mīkini pale. ʻO ka lepo, ka wai a me ke one e kahe ana, e mālama i ke kumukūʻai o ka haki ʻana i ka pā mau, a hoʻemi pū i ka haumia o ka lepo a me ka walaʻau.
4, e pili ana i ka hoʻokele waiwai, ke hoʻohālikelike ʻia me ke kila maʻamau, ʻoi aku ka māmā o ka hoʻoikaika ʻana i ke aniani fiber, e hōʻemi ana i ke kumukūʻai o ka hale, a i ka manawa like, no ka nui o ka hale aniani fiber, hoʻemi ia i ka laulā o ka pā diaphragm, hoʻopakele ka helu o ka pā diaphragm interface I-beam a i ʻole ka paipu laka, a mālama i ke kumukūʻai.

Nā hiʻohiʻona opulupuluhoʻoikaika aniani
1, ka ikaika tensile kiʻekiʻe: ʻoi aku ka maikaʻi o ka ikaika tensile o ka fiberglass reinforcement ma mua o ke kila maʻamau, ʻoi aku ka kiʻekiʻe ma mua o 20% o ke kila kikoʻī like, a me ke kūpaʻa luhi maikaʻi.
2, ke kaumaha māmā: ʻo ka nui o ka fiberglass hoʻoikaika ʻia he 1/4 wale nō o ka nui like o ke kila, a ʻo ka mānoanoa ma waena o 1.5 a me 1.9 (g/cm3).
3, hiki ke pale aku i ka ʻakika a me ka alkali a me nā mea kemika ʻē aʻe i ka erosion o nā ions chloride a me nā haʻahaʻa pH haʻahaʻa, ʻoi aku ka ikaika o ka corrosion o nā pūhui kalapona a me nā pūhui chlorine.
4、Ka paʻa mea ikaika: ʻoi aku ka nui o ka hoʻonui wela o ka hoʻoikaika fiberglass i ka sima ma mua o ke kila, no ka mea, ʻoi aku ka ikaika o ka hoʻoikaika ʻana i ka fiberglass ma mua o ka paʻa paʻa.
5, hoʻolālā ikaika: paʻa ka modulus elastic o ka fiberglass reinforcement, paʻa ka nui ma lalo o ke koʻikoʻi wela, ke kulou a me nā ʻano ʻē aʻe e hiki ke hoʻohālikelike ʻia, hana palekana maikaʻi, non-thermal conductivity, non-conductive, flame retardant anti-static, ma o ka hoʻololi ʻana i ke ʻano a me ka hui ʻana metala ʻaʻole e hoʻohua mai i nā huna huna.
6, ikaika permeability i magnetic hawewe: fiberglass reinforcement mea he non-magnetic mea, i loko o ka non-magnetic a electromagnetic lālā paʻa pono ole e hana demagnetization lapaʻau.
7, hana maʻalahi: hiki ke hana ʻia ka fiberglass reinforcement e like me nā koi o ka mea hoʻohana no nā ʻano ʻāpana like ʻole a me nā lōʻihi o nā ʻāpana maʻamau a me nā ʻāpana maʻamau, ma ka pūnaewele hoʻopaʻa ʻana i loaʻa i ka lipine tensioning non-metallic, hana maʻalahi.

ʻO ka mea i luna nei ka hoʻolauna ʻana i nā pono a me nā pōʻino o ka fiberglass reinforcement a me ke kila maʻamau, fiberglass reinforcement e like me nā mea hana kiʻekiʻe kiʻekiʻe, hoʻohana nui ʻia i nā tunnels subway (pale), nā alaloa, nā alahaka, nā mokulele, nā docks, stations, water conservancy projects. , 'enekinia ma lalo o ka honua a me nā māla ʻē aʻe, hiki ke hoʻololi i nā mea kanu hoʻomaʻemaʻe wai, nā mea kanu kemika, nā pahu electrolytic, nā uhi manhole, nā papahana pale kai a me nā kaiapuni corrosive ʻē aʻe.
