ʻO ka ʻenehana hoʻoikaika kino kino ma lalo o ka wai

Lima puluniu anianilalo wai anticorrosion hoʻoikaika 'enehana he synthesis o ka hale a me ka haole pili 'enehana a hui pu me Kina 'āina kūlana, a me ka hoʻomaka 'ana o ka hydraulic concrete anticorrosion reinforcement hana 'enehana.

Loaʻa i ka ʻenehana nā hiʻohiʻona nui:

1. hiki ke pale aku i ka pōʻaiapuni i hoʻokumu ʻia e ka maloʻo a me ka pulu, ka wela a me ke anu, ka maloʻo a me ka hoʻoheheʻe ʻana a me nā pilina ʻē aʻe, a me nā kahe wai, ke kai moana, ka wai ʻino, nā electrolytes a me nā hopena corrosive hoʻomau a intermittent, maikaʻi loa ka lōʻihi.

2. Ma muli o ka inertia o ka lima fiberglass i ka hopena kemika, hiki iā ia ke pale aku i nā ʻano mea hana kemika a pau, a he ikaika kona kūpaʻa ʻana i ka waikawa a me ka alkali, no laila hiki iā ia ke pale aku i ka ʻino o ka wai kai.

3. No ka mea, ʻaʻole ia e paʻa i ka wai, ʻoi aku ka ikaika a me ka paʻa paʻa (ka ikaika hoʻopaʻa ʻana a hiki i 2.5MPa) i ka hana ʻana ma lalo o ka wai. ʻOi loa i ka "hana ma lalo o ka wai", me ka ʻole o ka pono e kūkulu i nā cofferdams a me nā lako waiwai waiwai, kahi hoʻonohonoho o ka ʻōnaehana hoʻōla manawa, mālama kālā, mālama kālā maikaʻi loa i ka ʻōnaehana anti-corrosion.

4. ma lalo o ka wai anti-dispersion grout a me ka epoxy grout hiki ke komo i loko o nā māwae o ka substrate, e hana ana i kahi rivet, ʻoi aku ka maikaʻi o ka hoʻoponopono ʻana a me ka hoʻoikaika ʻana i ka hale kumu.

ʻO ka lima kīʻaha aniani kūikawā:

KūikawāMāmā Uila AnianiHe mea hana hou ia i hana ʻia me ka resin synthetic a me ka fiber aniani e ka hana composite. He mea polymer thermosetting me kēia mau ʻano:

ʻO ke kaumaha māmā a me ka ikaika kiʻekiʻe: ʻo ka pili pili ma waena o 1.5 ~ 2.0, ʻo 1/4 ~ 1/5 wale nō o ke kila kalapona, akā kokoke a ʻoi aku ka ikaika o ka tensile i ke kila kalapona, a hiki ke hoʻohālikelike ʻia ka ikaika kikoʻī me ke kila kila kila kiʻekiʻe. No laila, i loko o ka mokulele, rockets, spacecraft, kiʻekiʻe-press ipu, a me nā huahana ʻē aʻe e pono e hoʻemi i ke kaumaha o ka noi, loaʻa nā hopena maikaʻi loa. ʻO ka tensile, flexural a me ka ikaika compressive o kekahi mau epoxy FRP hiki ke piʻi ma luna o 400 MPa.

ʻO ke kūpaʻa ʻino maikaʻi: ʻO ka GRP kahi mea kūʻē i ka corrosion maikaʻi me ke kūpaʻa maikaʻi i ka lewa, ka wai, a me ka nui o ka nui o nā waikawa, alkalis, paʻakai, a me nā ʻano ʻaila a me nā mea hoʻoheheʻe. Ua hoʻohana ʻia i nā ʻano āpau o ke kemika anti-corrosion, a ke hoʻololi nei i ke kila kalapona, ke kila kila, ka lāʻau, 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 microwave permeability, ua hoʻohana nui ʻia i nā radomes.

Maikaʻi thermal waiwai: GRP haʻahaʻa thermal conductivity, lumi wela no 1.25 ~ 1.67kJ / (mhK), wale 1/100 ~ 1/1000 o ka metala, he maikai loa thermal insulation mea. I ka hihia o ka transient ultra-kiʻekiʻe wela, ʻo ia ka pale wela kūpono a me nā mea ablation-resistant, hiki ke pale i ka mokulele i 2000 ℃ a i ʻole ke kū ʻana i ka ea holo wikiwiki.

Hoʻolālā maikaʻi:

① Hiki ke hoʻolālā ʻia nā ʻano huahana a pau e like me nā pono e hoʻokō i nā koi o ka hoʻohana ʻana, hiki ke hana i nā huahana i kahi kūpaʻa maikaʻi.

Hiki iā ② ke koho piha i ka mea e hoʻokō ai i ka hana o ka huahana, e like me: hiki ke hoʻolālā i ka corrosion-resistant, ke kiʻekiʻe o ka mahana wela, ʻo ka huahana kahi kuhikuhi o ka ikaika kiʻekiʻe, nā waiwai dielectric maikaʻi, a pēlā aku.

Hana maikaʻi loa:

① E like me ke ʻano o ka huahana, nā koi ʻenehana, hoʻohana a me ka helu o ke koho maʻalahi o ke kaʻina hana.

② maʻalahi ke kaʻina hana, hiki ke hoʻoheheʻe ʻia i hoʻokahi manawa, ʻoi aku ka maikaʻi o ka hopena o ka hoʻokele waiwai, ʻoi aku hoʻi no nā ʻano paʻakikī, ʻaʻole maʻalahi e hana i kahi helu liʻiliʻi o nā huahana, ʻoi aku ka maikaʻi o kāna kaʻina hana.
