Nā paipu keleawe / keleawe CuZn36

ʻO CuZn36, kahi hui keleawe-zinc, i ʻike nui ʻia ʻo ia he keleawe. ʻO ke keleawe CuZn36 kahi hui e loaʻa ana ma kahi o 64% keleawe a me 36% zinc. ʻOi aku ka haʻahaʻa o ke keleawe o kēia hui i loko o ka ʻohana keleawe akā ʻoi aku ka nui o ka zinc, no laila he mau waiwai kino a me nā ʻano mechanical kūikawā i kūpono no nā noi ʻoihana like ʻole. Ma muli o kona mau waiwai mechanical maikaʻi loa a me nā waiwai hana, hoʻohana nui ʻia ʻo CuZn36 i ka hana ʻana i nā ʻāpana mechanical like ʻole, nā mea paʻa, nā pūnāwai, a pēlā aku.

Nā waiwai mīkini

ʻOkoʻa nā waiwai mechanical o CuZn36 e like me nā kūlana mālama wela like ʻole. Eia kekahi mau ʻikepili hana maʻamau:

· Ikaika tensile (σb): Ma muli o ke kūlana mālama wela, ʻokoʻa nō hoʻi ka ikaika tensile, ma waena o 460 MPa a me 550 MPa.

·Ka ikaika hua (σs): Ma muli o ke kūlana mālama wela, ʻokoʻa nō hoʻi ka ikaika hua.

·Elongation (δ): He ʻokoʻa nā koi o nā uea o nā anawaena like ʻole no ka elongation. No ka laʻana, no nā uea me ke anawaena o 4mm a emi mai paha, pono e hiki aku ka elongation ma mua o 30%.

·Paʻakikī: ʻO ka paʻakikī o CuZn36 mai HBW 55 a 110, a ʻo ka waiwai kikoʻī e pili ana i ke kūlana lapaʻau wela kikoʻī

Nā waiwai hana

Loaʻa iā CuZn36 nā waiwai hana anu maikaʻi a hiki ke hana ʻia ma ke kāwili ʻana, extrusion, stretching a me ka ʻōwili anu. Ma muli o ke kiʻekiʻe o ka zinc, piʻi ka ikaika o CuZn36 me ka piʻi ʻana o ka zinc, akā i ka manawa like, emi ka conductivity a me ka ductility. Eia kekahi, hiki ke hoʻopili ʻia ʻo CuZn36 ma o ka brazing a me ke soldering, akā ma muli o ke kiʻekiʻe o ka zinc, pono e uku ʻia ka nānā kūikawā i ka wā e kuʻi ai.

Ke kū'ē ʻana i ka palaho

Loaʻa iā CuZn36 ke kūpaʻa maikaʻi i ka wai, ka mahu wai, nā ʻano paʻakai like ʻole a me nā wai organik he nui. He kūpono hoʻi ia no nā ʻāina lewa ʻāina, kai a me nā ʻoihana. Ma lalo o kekahi mau kūlana, hiki iā CuZn36 ke hana i ka haki ʻana o ka corrosion stress i ka lewa ammonia, akā hiki ke hoʻopau ʻia kēia corrosion ma ka wehe ʻana i ke kaumaha kūloko i nā hihia he nui

Nā wahi noi
Loaʻa pinepine ka keleawe CuZn36 ma nā kahua aʻe:

ʻEnekinia mīkini: hoʻohana ʻia e hana i nā ʻāpana e pono ai kekahi paʻakikī a me ke kūpaʻa ʻana i ka ʻaʻahu, e like me nā kiwikā, nā ʻāpana pamu, nā kia a me nā bearings.

ʻEnekinia uila: Ma muli o kona alakaʻi uila maikaʻi, hoʻohana ʻia ia e hana i nā mea hoʻohui uila, nā kumu, a pēlā aku.

Nā mea hoʻonaninani a me nā hana lima: Ma muli o kona mau waiwai hana maikaʻi a me ke kala kū hoʻokahi o ke keleawe, kūpono hoʻi ka hui CuZn36 no ka hana ʻana i nā mea hoʻonaninani a me nā hana lima.

He nui nā noi o CuZn36, e like me:

· Nā ʻāpana i huki hohonu ʻia

·Nā huahana metala

· ʻOihana uila

·Nā mea hoʻohui

· ʻEnekinia mīkini

· Nā hōʻailona a me nā mea hoʻonaninani

·Nā mea kani, a pēlā aku.510

ʻŌnaehana mālama wela

ʻO ka ʻōnaehana mālama wela o CuZn36 e komo pū ana me ka annealing, quenching a me ka tempering, a me nā mea ʻē aʻe. Hiki i kēia mau ʻano mālama wela ke hoʻomaikaʻi i kona mau waiwai mechanical a me ka hana hana

Hōʻuluʻulu Manaʻo：

Ma ke ʻano he mea hoʻohuihui keleawe waiwai a hana kiʻekiʻe, he kuleana koʻikoʻi ʻo CuZn36 i nā noi ʻoihana. Hoʻohui ia i ka ikaika kiʻekiʻe me ka hiki ke hana maikaʻi a kūpono no nā ʻano noi ʻenekinia like ʻole, ʻoi aku hoʻi i ka wā e hana ai i nā ʻāpana e pono ai nā waiwai mechanical maikaʻi a me ke kūpaʻa ʻana i ka pala. Ma muli o kona mau waiwai piha maikaʻi, ʻo CuZn36 ka mea makemake nui ʻia ma nā ʻoihana he nui.

Welina mai e hoʻokaʻaʻike mai iā mākou no nā kikoʻī hou aku e pili ana i nā paipu keleawe a keleawe paha!
