Ua hana au me nā mea he nui e kū'ē ana i ka wai kai i nā makahiki i hala iho nei, a ke piʻi mau nei nā mea hao keleawe-nickel (cupronickel) e like me C70600 (90/10) a me C71500 (70/30) ma ke ʻano he koho hilinaʻi no nā mea i hōʻike ʻia i ka wai paʻakai. Hāʻawi ka hoʻohui nickel i ke keleawe i kēlā lihi hou aʻe e kū'ē i ka pala a me ka biofouling me ka ʻole o ka hoʻololi ʻana iā ia he palupalu a nāwaliwali paha. ʻAʻole ia ka mea makepono loa ma mua, akā i ka wā e kamaʻilio ai ʻoe no nā makahiki he ʻumi o ka lawelawe ʻana i nā wahi kai ʻino, hoʻopau pinepine ʻo CuNi i ka mālama kālā i ka wā lōʻihi. I ka makahiki 2026, me ka hoʻonui ʻana o nā mahi makani ma waho a me ka ulu ʻana o nā mea kanu desalination, ke ʻike nei kēia mau mea hao i ka hoʻohana paʻa ʻana kahi ʻaʻole hiki ke hāʻule.
Eia kahi nānā pono ʻana i nā ʻano a mākou e hana pinepine ai, nā mea kūpono iā lākou, nā ʻoihana e hilinaʻi nei iā lākou, pehea lākou e hoʻohālikelike ai i ka tini a me ke keleawe alumini, a no ke aha he paʻakikī ke hoʻololi i ko lākou wahi kūpono.
Nā koʻokoʻo keleawe-nickel, nā papa, nā paipu, a me nā ʻāpana moana maʻamau e like me nā condensers a me nā piping.
Nā ʻAno Maʻamau a me kā lākou Hana Maikaʻi
Ua ʻōwili ʻia ʻo CuNi, hoʻopuka ʻia, a huki ʻia paha i loko o nā ʻano e paʻa ai i nā kūlana paʻakikī:
- Nā koʻokoʻo/nā kaola→ Nā poepoe paʻa a i ʻole hexagons no nā mea hoʻopaʻa, nā kumu valve, a i ʻole nā ʻau pamu - hana maikaʻi nā mīkini a pale aku i ka ʻānai ʻia ʻana o ke kai e kahe ana.
- Nā Papa→ ʻŌpala pālahalaha no ka uhi ʻana i nā ʻili o ka moku, nā pūpū hoʻololi wela, a i ʻole nā panela paepae ma waho o ke kai - maʻalahi ke hoʻoheheʻe a hana i nā hale nui.
- Nā Paipu→ Paipu humuhumu ʻole a i ʻole i hoʻopaʻa ʻia no nā condensers, nā mea hoʻololi wela, a i ʻole nā paipu wai kai - ke kumu no ka hoʻoili wai me ka liʻiliʻi o ka haumia.
Mālama mākou i kēia mau mea ma nā papa maʻamau, e like menā koʻokoʻo keleawe-nickel, nā pā, a menā paipu- nā wahi hoʻomaka paʻa noHana ʻana o CNCa i ʻole nā papahana maʻamau.
Nā ʻoihana e hoʻohana nui ana iā ia
Loaʻa maoli ka nickel keleawe i kona mālama ʻana i nā ʻāpana kaumaha o ka wai paʻakai:
- Ke kūkulu ʻana i nā moku a me nā moku (ka uhi ʻana o ka ʻili, nā paipu, nā propellers)
- ʻAila/kinoea a me ka makani ma waho (nā kahua, nā lako ma lalo o ka moana)
- Nā hale hana desalination (nā mea hoʻoheheʻe wai, nā mea hoʻololi wela)
- Ka hana mana (nā ʻōmole condenser ma nā hale hana kahakai)
- Ka hana kemika (lawelawe ʻana i ka wai paʻakai)
Ma kahi o ka wai kai maka a i ʻole ka brine e neʻe ana ma o nā ʻōnaehana.
Pehea e hoʻopaʻa ai - A no ke aha ʻo ia ka mea kūpono loa
E kū'ē i ke keleawe tin (paʻa no nā bearings a me ke komo ʻana), ʻoi aku ka maikaʻi o ke kūpaʻa ʻana o CuNi i ka palaho kai a me ka biofouling - hiki i ke keleawe tin ke hoʻokahe a hoʻopau paha i ka wai i nā kahe kai ikaika. E kū'ē i ke keleawe alumini (paʻakikī i ka ikaika a me ka cavitation), hāʻawi ke keleawe-nickel i ke kūpaʻa ʻana i ka palaho holoʻokoʻa i ka wai kai, ʻoi aku ka ductility no ka hoʻokumu ʻana, a me nā waiwai anti-biofouling koʻikoʻi (ʻaʻole paʻa ka ulu ʻana o ke kai).
ʻO ke kī lanakila: ke kūpaʻa kūikawā i ka ʻino-ka pala i loko o ka wai kai e holo wikiwiki ana, ke kūpaʻa kūlohelohe i nā antimicrobial/biofouling, ka ikaika maikaʻi me ka hiki ke hoʻopili ʻia, a me ka hilinaʻi lōʻihi.
E hoʻāʻo e hoʻololi? Hana maikaʻi ke kila kila a i ʻole ka titanium akā he nui ke kumukūʻai a hiki ke ʻeha i ka pala o ka crevice a i ʻole ka galling. He nui loa ka Super duplex no nā polokalamu he nui. No nā paipu wai kai, nā condensers, a i ʻole nā hale ma waho e pono ai ka hana i hōʻoia ʻia, haʻahaʻa ka mālama ʻana ma luna o 20-30 mau makahiki, ʻo ke keleawe-nickel ka mea maʻamau, koho i hoʻāʻo ʻia ma ke kahua - ʻo nā koho ʻē aʻe ke ʻano o nā kumukūʻai mua kiʻekiʻe, nā nānā hou aku, a i ʻole ke ola lawelawe pōkole.
He aha ka mea e hiki mai ana no Copper-Nickel
Me ka nānā hou aku i ka ikehu kai hoʻomau, ke loaʻa nei ka makemake i nā māka nickel kiʻekiʻe no nā kūlana paʻakikī.
Inā ʻoe e noʻonoʻo nei i nā ʻōnaehana wai kai a i ʻole nā ʻāpana moana, e nānā i kā mākouka laulā o ke keleawe-nickel alloy or e hoʻokaʻaʻike mai– ua hoʻolako mākou i nā mea he nui e ikaika mau ana ma hope o nā makahiki he ʻumi.
ʻAʻole paha he mea hoʻonani ke keleawe-nickel, akā mālama mālie ia i nā ʻoihana koʻikoʻi e holo ana ma nā wahi ʻino loa.
