keleawe pale dezincification (DZR keleawe) ua lilo i mea nui i ka oihana paipu, ʻoi aku no nā noi valve. Ka helu o nā mea hoʻohana e koho ʻO nā pāpaʻi keleawe DZR ke mahuahua nei, e hōʻike ana e piʻi mau ana nā koi o ka lehulehu no ka maikaʻi o ka wai a me nā mea valve.
He aha ka DZR Brass?
keleawe DZR(Palekana Dezincification) he hao keleawe kūikawā i hana ʻia e kūʻē i ka dezincification, he kaʻina hana ʻino e hōʻeha i ke keleawe maʻamau i kekahi mau kaiapuni.
He aha ka Dezincification?
Dezincification, a i ʻole ka leaching o ka zinc, hiki ke hoʻopau ʻia ka zinc mai ka hui keleawe, Ke haʻalele nei ma hope o kahi mea pena.
ʻO ka loaʻa ʻana o ka dezincification corrosion i loko o ke keleawe e pili kokoke ana i ka ʻike zinc i loko o nā alloy copper-zinc.. ʻO ka maʻamau, ke loaʻa ka zinc ma lalo 15%, ʻAʻole paha e hiki mai ka corrosion dezincification; Akā naʻe,, hoʻopilikia ʻia ke kūpaʻa erosion o ka alloy. ʻO ka hoʻonui ʻana i ka ʻike zinc hiki ke hoʻonui i ka ikaika a me ke kūpaʻa erosion o ka alloy, akā, hoʻonui ia i ka pilikia o ka corrosion dezincification.
Ke ʻoi aku ka nui o ka zinc 20%, ʻoi aku ka maikaʻi o ka hoʻoheheʻe ʻana o ka zinc i loko o ka wai. Ke waiho nei kēia kaʻina hana i ka porous o ka hale keleawe, e alakai ana i ka emi ana o ka ikaika o ke keleawe.
ʻOi aku ka nui o ka dezincification o ke keleawe i loko o ka wai kai a me nā mea paʻakai, e like me NaCl a me CuCl2.
Loaʻa ka mīkini pale i ke keleawe DZR ma o ka hoʻomalu ʻana i ka haku mele. Hoʻohui i nā mea liʻiliʻi e like me As/Sb/P/B/Al a me ka honua lae, a me ka mālama ʻana i nā lakio keleawe-a-zinc kikoʻī, e hana i kahi huila e pale pono ai i ka hoʻolele zinc i nā kūlana wai.
Nā Papa keleawe a me nā haku mele DZR
Nā Papa keleawe maʻamau

Nā Kūlana a me nā Kūlana o kēia wā
Ua hoʻokumu nā ʻāina a me nā ʻāina i nā kūlana no ka keleawe DZR a me kāna hoʻohana ʻana i nā valve:
Hui ʻEulopa: I 12165 (Ke keleawe a me ke keleawe – ʻO ka waiwai hoʻoheheʻe ʻia a me ka hana ʻole ʻia)
Aupuni Mōʻī Hui Pū ʻia: BS en 12165, Bs 6920 (ʻO ke kūpono o nā huahana non-metallic no ka hoʻohana ʻana i ka pilina me ka wai i manaʻo ʻia no ka ʻai kanaka)
Australia/Nuilani: AS/NZS 4020 (ʻO ka hoʻāʻo ʻana i nā huahana no ka hoʻohana ʻana i ka pilina me ka wai inu)
ʻAmelika Hui Pū ʻIa: ASTM B124 (Hōʻike maʻamau no ka Copper a me Copper Alloy Forging Rod, Bar, a me na Kinohi), NSF / ASI 61 (Nā ʻāpana ʻōnaehana wai inu – Nā hopena olakino)
Anterhi: Iso 6509 (ʻO ka ʻinoʻino o nā metala a me nā mea hao – ʻO ka hoʻoholo ʻana i ke kūʻē dezincification o nā ʻāpana keleawe me ka zinc)
Nā Koina Hoailona no nā Pono DZR
Loaʻa i nā ʻāina like ʻole nā koi kūikawā no ka hōʻailona ʻana i nā mea keleawe DZR:
Hoailona pono ia na lako paipu i ku i ka dezincification, me nā leka “CR” (Pale ʻino) a i ʻole DZR (pale i ka dezincification) ma UK, a me na palapala “DR” (pale i ka dezincification) ma Australia.
Nā ʻano hoʻāʻo no DZR Brass
Hōʻike ʻia ke ala hoʻāʻo mua no ka keleawe DZR ma ISO 6509:
① Hoʻomākaukau laʻana: Hoʻomaʻemaʻe ʻia nā mea hoʻohālike.
② Hōʻike: Hoʻokomo ʻia nā laʻana i loko o ka solution copper chloride ma nā wela kiʻekiʻe (maʻa mau 75°C) no ka manawa i oleloia (maʻamau 24 hola).
③ Ana: Ma hope o ka hōʻike, ua ʻāpana ʻia nā laʻana a ua ana ʻia ka hohonu o ka dezincification me ka hoʻohana ʻana i nā ʻenehana microscopy.
④ Loiloi: Hoʻohālikelike ʻia ka hohonu dezincification me nā palena i kuhikuhi ʻia, maʻamau emi mai 200 micrometers no ka ho'āʻo 24-hola.
ʻO nā pono o DZR Brass Valves
Hoʻonui i ka pale ʻana i ka corrosion, kūʻē i ka dezincification
ʻOi aku ka lōʻihi o ka lawelawe ʻana i ka hoʻohālikelike ʻana i nā valve keleawe maʻamau
Ka mālama pono ʻana o ke kino i nā kūlana wai ikaika
ʻO ka hoʻokō ʻana i nā lula wai inu koʻikoʻi
BMAG DZR Nā Pahu keleawe
Hōʻike nā pahu keleawe DZR i kahi holomua nui i ka ʻenehana paipu, hāʻawi ʻoi aku ka maikaʻi o ka corrosion a me ka lōʻihi i nā ʻōnaehana wai. BMAG DZR kiwi keleawe a KahawaiOli e hoʻoikaika i ka ikaika o nā ʻōnaehana i ʻike ʻia i ka wai corrosive loa, e ho'ēmi i ka pono no ka mālama pinepine a me ka hoʻololi hapa.
