ʻO Jiangsu HELIKE Fluid Technology Co., Ltd. he lālā nona piha o Dongxu Hydraulics.He mea kūikawā ia i ka noiʻi a me ka hoʻomohala ʻana, ka hoʻolālā ʻana, ka hana ʻana a me ke kūʻai aku ʻana i nā mea hoʻololi wela alumini plate-fin.
Mechanism of Vacuum Aluminum Brazing
Hoʻohana ka ʻenehana brazing alumini vacuum i ka alumini alumini me kahi wahi hoʻoheheʻe haʻahaʻa ma mua o ka alumini e like me ka mea brazing.Hoʻomaʻamaʻa kēia ʻenehana i ka weld a me ka solder ma luna o ka helu heheʻe o ka solder.Akā ma lalo o ka wela hoʻoheheʻe ʻana o ka metala kumu, hoʻopiha ka solder wai i ka liʻiliʻi liʻiliʻi ma waena o nā mea hana ʻelua ma ka infiltration a diffuses me ka metala kumu, a laila e ʻike ai i ke ʻano o ka hoʻopili ʻana i nā mea hana e welded.

①He haʻahaʻa ka wela wela, no laila, ʻaʻole e hoʻopilikia ʻia nā waiwai kino a me nā kemika o ka metala kumu.
② Hiki ke wili ʻia nā kaukani o nā ʻāpana paʻakikī i ka manawa hoʻokahi.
③ He liʻiliʻi ka deformation o nā ʻāpana, a he maʻalahi ke hōʻoia i ka nui o ka hui.
④He mea maikaʻi ka hoʻomehana ʻana i loko o kahi kaʻa e hoʻoneʻe i ka momona a me ke kiʻiʻoniʻoni oxide ma ka ʻili o ka mea hana, a kiʻekiʻe ka ʻōlinolino o nā ʻāpana ma hope o ke kuʻi ʻana.
⑤ʻAʻole koi ʻia ka flux, ʻaʻohe pono e hoʻomaʻemaʻe ma hope o ke kuʻi ʻana.
⑥ Hiki ke hoʻokō ʻia ka hoʻopaʻa ʻana a me ke kinai ʻana (a i ʻole kekahi mālama wela) i ka manawa like.
Nā ʻano a me nā pilikia o ke kaʻina hana brazing alumini alumini
Ma muli o nā waiwai kino a me nā kemika o ka alumini alumini, e kū mai kekahi mau pilikia a me nā hiʻohiʻona i ka wā o ke kaʻina brazing:
ʻO nā mea kemika o ka alumini he mea ikaika loa, a ikaika loa kona pilina me ka oxygen.I ka ea ma ka lumi wela, e hoʻohui ʻia ka alumini a me ka oxygen i kahi AL paʻa2O3kiʻiʻoniʻoni me ka mānoanoa a hiki i ka 0.1 μm.ʻO ke kiʻiʻoniʻoni oxide he ʻeleʻele loa, a ʻo kona wahi hoʻoheheʻe he kiʻekiʻe e like me 2050 ° C, ʻoi aku ma mua o ka wela hoʻoheheʻe o ka alumini alumini.I ka manawa like, e keakea ia i ka hoʻopaʻa maikaʻi ʻana ma waena o nā metala, a hana maʻalahi i nā slag inclusions a me nā pores.No laila, he mea koʻikoʻi loa ka hoʻomaʻamaʻa mua ʻana o nā alumini alumini a me ka pale ʻana a i ʻole ka hoʻohaʻahaʻa ʻana i ka hoʻokumu ʻana o ke kiʻi ʻoniʻoni oxide i ka mokuʻāina.No laila, he mea pono loa e mālama i kahi ʻūhā kiʻekiʻe i loko o ka umu, e hoʻemi i ka hoʻokumu ʻana o ke kiʻi oxide a i ʻole e wehe i ke kiʻi oxide i ka wā o ka brazing kaʻina, ʻoi loa i ka ʻāpana kaʻina o ka hoʻoheheʻe solder.
ʻO ka mahana hoʻoheheʻe o ka mea hoʻoheheʻe alumini i hoʻokumu ʻia he 50-80 ° C wale nō ka ʻokoʻa mai ka helu hoʻoheheʻe o ka alumini alumini nui, a he liʻiliʻi ka wahi hana.No laila, pono e koho pono i ka solder a hoʻoholo i ka hoʻoheheʻe ʻana o ka mea kūʻai aku, a i ka manawa like, pono e loaʻa i ka solder a me ka metala kumu ka pulu maikaʻi.
ʻO ka koho kūpono o ka mahana wela a me ka manawa paʻa he mea nui loa ia e hana i kahi hui brazed maikaʻi a hoʻomaikaʻi i ka ikaika o ka hui.
He kiʻekiʻe ka pololei o ka nui o nā ʻāpana brazing: no ka laʻana, mālama ʻia ka hoʻomanawanui ʻana o ka hana fin ma ± 0.03mm e like me kā mākou ʻike, a pono e mālama pono ʻia ka maikaʻi o ka hui.
