ʻUmi lima anianiʻO ka ʻenehana hoʻoikaika anticorrosion ma lalo o ka wai he hui pū ʻana o nā ʻenehana pili kūloko a me nā ʻāina ʻē a hui pū ʻia me nā kūlana aupuni o Kina, a me ka hoʻomaka ʻana o ke kahua o ka ʻenehana kūkulu hoʻoikaika anticorrosion beton hydraulic.
Loaʻa i ka ʻenehana nā hiʻohiʻona koʻikoʻi:
1. hiki ke pale aku i ke kaʻapuni o ke aniau i hoʻokumu ʻia e ka maloʻo a me ka pulu, ka wela a me ke anu, ka hau a me ka heheʻe ʻana a me nā pilina ʻē aʻe, a me nā kahe wai, nā kai moana, nā wai hoʻoneoneo, nā electrolytes a me nā hopena ʻino mau a i ʻole intermittent, maikaʻi loa ka lōʻihi.
2. Ma muli o ka inertia o ka ʻūlū fiberglass i ka hopena kemika, hiki iā ia ke kū'ē i nā ʻano kemika āpau, a he kūpaʻa ikaika kona i ka waikawa a me ka alkali, no laila hiki iā ia ke kū i ka pala o ka wai kai.
3. No ka mea, ʻaʻole ia e pili i ka wai, he ikaika loa kona hoʻopaʻa ʻana a paʻa hoʻi (ikaika hoʻopaʻa a hiki i ka 2.5MPa) i ke kūkulu ʻana ma lalo o ka wai. ʻOi loa aku hoʻi i ka "kūkulu ʻana ma lalo o ka wai", me ka ʻole o ka pono e kūkulu i nā cofferdams a me nā lako hoʻokahe wai pipiʻi, he hoʻonohonoho o ka ʻōnaehana anti-corrosion maikaʻi loa e mālama ana i ka manawa, ka hana, a me ke kālā.
4. Hiki i ka grout anti-dispersion underwater a me ka epoxy grout ke komo i loko o nā māwae o ka substrate, e hana ana i kahi ʻano rivet, hoʻoponopono maikaʻi a hoʻoikaika i ka ʻano mua.
ʻUmiʻumi aniani kūikawā:
KūikawāʻUmiʻumi anianihe mea hana hou i hana ʻia me ka resin synthetic a me ke aniani fiber ma o ke kaʻina hana composite. He mea polymer thermosetting me nā ʻano penei:
Māmā ke kaumaha a me ka ikaika kiʻekiʻe: ʻo ka nui o ka mānoanoa ma waena o 1.5 ~ 2.0, 1/4 ~ 1/5 wale nō o ke kila kalapona, akā kokoke a ʻoi aku paha ka ikaika tensile i ke kila kalapona, a hiki ke hoʻohālikelike ʻia ka ikaika kikoʻī me ke kila alloy kiʻekiʻe. No laila, i loko o ka mokulele, nā rockets, nā mokulele mokulele, nā ipu kiʻekiʻe, a me nā huahana ʻē aʻe e pono ai ke hoʻemi i ke kaumaha o ka noi, loaʻa nā hopena maikaʻi loa. Hiki i nā ikaika tensile, flexural a me compressive o kekahi mau epoxy FRP ke piʻi ma luna o 400 MPa.
Kū'ē maika'i i ka palaho: He mea kū'ē maika'i ka GRP i ka palaho me ke kū'ē maika'i i ka lewa, ka wai, a me nā ʻano nui o nā waikawa, alkalis, pa'akai, a me nā ʻano aila like ʻole a me nā mea ho'ohehe'e. Ua ho'ohana 'ia i nā 'ano āpau o ka kemika anti-corrosion, a ke pani nei i ke kila kalapona, ke kila kila, ka lā'au, nā metala non-ferrous a pēlā aku.
Nā waiwai uila maikaʻi: He mea maikaʻi loa iamea hoʻokaʻawale, hoʻohana ʻia e hana i nā insulators. Hiki i ke alapine kiʻekiʻe ke pale i nā waiwai dielectric maikaʻi. Maikaʻi ka permeability microwave, ua hoʻohana nui ʻia i nā radomes.
Nā waiwai wela maikaʻi: ʻO ka hoʻokele wela haʻahaʻa GRP, ʻo ka mahana o ka lumi he 1.25 ~ 1.67kJ / (mhK), ʻo 1/100 ~ 1/1000 wale nō o ka metala, he mea hoʻomehana wela maikaʻi loa ia. I ke ʻano o ka mahana kiʻekiʻe loa, ʻo ia ka pale wela kūpono a me nā mea pale ablation, hiki ke pale i ka mokulele i 2000 ℃ a ʻoi aku paha e kū i ke kahe ʻana o ka ea wikiwiki.
Ka maikaʻi o ka hoʻolālā ʻana:
① Hiki ke hoʻolālā maʻalahi ʻia nā ʻano huahana kūkulu āpau e like me nā pono e hoʻokō ai i nā koi o ka hoʻohana ʻana, hiki ke hoʻolilo i nā huahana i kahi kūpaʻa maikaʻi.
② hiki ke koho piha i ka mea e hoʻokō ai i ka hana o ka huahana, e like me: hiki ke hoʻolālā i kahi pale ʻana i ka pala, ke kūpaʻa wela kiʻekiʻe, aia ka huahana i kahi kuhikuhi kikoʻī o ka ikaika kiʻekiʻe, nā waiwai dielectric maikaʻi, a pēlā aku.
Hana lima maikaʻi loa:
① E like me ke ʻano o ka huahana, nā koi loea, ka hoʻohana a me ka helu o nā koho maʻalahi o ke kaʻina hana hoʻoheheʻe.
② He maʻalahi ke kaʻina hana, hiki ke hoʻoheheʻe ʻia i hoʻokahi manawa, he mea koʻikoʻi ka hopena waiwai, ʻoiai no nā ʻano paʻakikī, ʻaʻole maʻalahi ke hana i kahi helu liʻiliʻi o nā huahana, ʻoi aku ka ʻike ʻia o kona kūlana kiʻekiʻe.
