Hoolei Aluminum-Silicon Alloy Radiator/ Exchanger no ka Boiler Kinohi Kino maoli
Mea Hoʻolauna
ʻO ke alumini alumini kiʻekiʻe-silikona he ʻāpana binary i haku ʻia me ke silikoni a me ka aluminika, a he mea hoʻokele wela metala. Hiki i ke kiʻekiʻe kiʻekiʻe-silicon alumini alumini mea hiki ke mālama i nā waiwai maikaʻi loa o ka silicon a me ka alumini, ʻaʻole e hoʻohaumia i ke kaiapuni, a ʻaʻole ʻino i ke kino o ke kanaka. ʻO ka mānoanoa o ke alumini alumini kiʻekiʻe-silikona ma waena o 2.4 ~ 2.7 g / cm³, a ʻo ka coefficient o ka hoʻonui wela (CTE) ma waena o 7-20ppm / ℃. ʻO ka hoʻonui ʻana i ka ʻike silika hiki ke hōʻemi nui i ka nui a me ka hoʻonui ʻana i ka wela o ka mea hao. I ka manawa like, ʻoi aku ka maikaʻi o ka conductivity thermal kiʻekiʻe-silikoni, ka paʻakikī kikoʻī a me ka rigidity, ka hana plating maikaʻi me ke gula, kālā, keleawe, a me ka nikela, weldable me ka substrate, a me ka maʻalahi machining. He mea hoʻopili uila me nā manaʻo noi ākea.
ʻO nā ʻano hana hana o nā mea hoʻohuihui alumini kiʻekiʻe-silikoni aluminika ka mea nui i kēia mau mea: 1) hoʻoheheʻe a hoʻolei ʻia; 2) ke ʻano infiltration; 3) ka pauda metallurgy; 4) keʻano kaomi wela wela; 5) ʻano hoʻoheheʻe wikiwiki / hoʻoheheʻe ʻia.
Kaʻina Hana Hana
1) Ka hoohehee a me ka hoolei ana
ʻO nā mea hana no ka hoʻoheheʻe ʻana a me ka hoʻolei ʻana he maʻalahi, haʻahaʻa ke kumu kūʻai, a hiki ke hoʻomaopopo i ka hana ʻoihana nui, a ʻo ia ke ʻano hoʻomākaukau nui loa no nā mea hao.
2) Keʻano impregnation
ʻO ke ʻano o ka impregnation ʻelua mau ʻano: kaomi infiltration ala a me pressureless infiltration ala. Hoʻohana ke ʻano infiltration kaomi i ke kaomi mechanical a i ʻole ke kaomi kinoea i hoʻoheheʻe ʻia e hoʻoheheʻe i ka metala kumu e hoʻoheheʻe ʻia i loko o ka lua hoʻoikaika.
3) Ka pauka metala
ʻO ka powder metallurgy ka hoʻopuehu ʻana i kekahi hapa o ka pauka aluminika, ka pauka silika a me ka hoʻopaʻa ʻana like ʻole, hoʻohui a hoʻohālikelike i nā pauka ma ke kaomi maloʻo, injection a me nā ʻano hana ʻē aʻe, a hope loa ka sinter i loko o kahi lewa pale e hana i kahi mea denser.
4) Keʻano kaomi wela wela
ʻO ke kaʻina hana hoʻoheheʻe wela e pili ana i kahi kaʻina sintering kahi e hana ʻia ai ke kaomi ʻana a me ka sintering kaomi i ka manawa like. ʻO kāna mau mea maikaʻi: ①He maʻalahi ka pauka i ka plastically kahe a densify; ②He pōkole ka mahana sintering a me ka manawa sintering; ③He kiʻekiʻe ka nui. ʻO ke kaʻina hana maʻamau: ma lalo o nā kūlana vacuum, hoʻokomo ʻia ka pauka i loko o ka lua mold, ua wela ka pauka i ka wā e kaomi ʻia, a ua hoʻokumu ʻia kahi mea paʻa a me nā mea like ʻole ma hope o ka manawa pōkole o ka pressurization.
5) Hoʻomoe wikiwiki / hoʻoheheʻe ʻia
ʻO ka ʻenehana hoʻoheheʻe wikiwiki / hoʻoheheʻe ʻia he ʻenehana paʻa wikiwiki. Loaʻa iā ia nā pono penei: 1) ʻaʻohe macro-segregation; 2) maikaʻi a ʻano like ʻole equiaxed crystal microstructure; 3) maikaʻi maikaʻi ka pae ua; 4) haʻahaʻa oxygen maʻiʻo; 5) hoʻomaikaʻi i ka hana ʻana i ka wela.
Hoʻokaʻawale
(1) Hypoeutectic silikon alumina aluminika loaʻa 9% -12% silika.
(2) Eutectic silikon alumina aluminika loaʻa 11% a 13% silika.
(3) ʻO ka ʻike silika o ka alumini alumini hypereutectic ma luna o 12%, ka nui ma ka laulā o 15% a 20%.
(4) ʻO ka poʻe i loaʻa i ka silicon content o 22% a ʻoi aʻe paha i kapa ʻia he kiʻekiʻe-silikon alumini alumini, a ʻo 25% -70% ka mea nui, a ʻo ka mea kiʻekiʻe kiʻekiʻe ma ka honua hiki ke hiki i 80%.
Palapala noi
1) Kiʻekiʻe-mana hoʻohui kaʻapuni puʻupuʻu: kiʻekiʻe-silikona alumini alumini e hāʻawi i ka wela wela;
2) Ka mea lawe: Hiki ke hoʻohana ʻia ma ke ʻano he wela kūloko e hana i nā mea i hoʻonohonoho pono ʻia;
3) Kiʻi Optical: hāʻawi ke kiʻekiʻe kiʻekiʻe kiʻekiʻe alumini alumini i ka hoʻonui haʻahaʻa wela, rigidity kiʻekiʻe a me ka hana;
4) Heat sink: Hāʻawi ke kiʻekiʻe kiʻekiʻe kiʻekiʻe alumini alumini i ka hoʻopau wela a me ke kākoʻo kūkulu.
5) Nā ʻāpana kaʻa: High-silicon alumina alumina mea (silicon content 20% -35%) he mau waiwai tribological maikaʻi loa, a hiki ke hoʻohana ʻia ma ke ʻano he mea hoʻohana ʻia i nā mea hoʻohana ʻokoʻa, nā mīkini mana, a me nā mīkini. mea paahana. , Hoʻohana nui ʻia nā mea hoʻopili kūikawā a me nā mea hana.
Loaʻa i ke kiʻekiʻe kiʻekiʻe-silicon alumina aluminika he ʻano o nā pono e like me ka gravity kikoʻī liʻiliʻi, ke kaumaha māmā, ka conductivity thermal maikaʻi, ka hoʻonui haʻahaʻa haʻahaʻa haʻahaʻa, ka paʻa o ka leo, ke kūpaʻa maikaʻi a me ke kūpaʻa corrosion maikaʻi, a hoʻohana nui ʻia e like me nā cylinder liners, pistons, a me nā rotor o nā ʻenekini kaʻa. , Nā pahu kaʻa a me nā mea ʻē aʻe.
