1. Nā pōmaikaʻi a me nā pōʻino o ka brazing alumini

ʻO Brazing kekahi o nā ʻano hoʻoheheʻe ʻekolu o ka hoʻoheheʻe fusion, ka wili puʻe, a me ka brazing.Hoʻohana ʻo Aluminum brazing i ka solder metala me kahi helu hoʻoheheʻe haʻahaʻa ma mua o ka metala weldment.E wela i ka solder a me ka weldment a hiki i lalo o ka wela hehee o ka weldment a ma luna o ka wela hehee o ka solder.He ala ia e hoʻohana ai i ka solder wai e hoʻomaʻemaʻe i ka metala o ka weldment, e hoʻopiha i ka hili lahilahi o ka hui a huki kekahi i kekahi me nā molekala metala o ka metala kumu e hoʻokō ai i ke kumu o ka hoʻopili ʻana i ka weldment.

pono :

1) Ma lalo o nā kūlana maʻamau, ʻaʻole e hoʻoheheʻe ʻia ka weldment i ka wā brazing;

2) Hiki ke hoʻopaʻa ʻia nā ʻāpana he nui a i ʻole ka hoʻolālā multi-layer a me nā weldments nested i ka manawa hoʻokahi;

3) Hiki iā ia ke hoʻopaʻa i nā ʻāpana lahilahi a lahilahi, a hiki ke hoʻopaʻa i nā ʻāpana me nā ʻokoʻa nui o ka mānoanoa a me ka mānoanoa;

4) Hiki ke hoʻokaʻawale ʻia a hoʻopaʻa hou ʻia nā hui brazed o kekahi mau mea kikoʻī.

hemahema :

No ka laʻana: 1) He haʻahaʻa ka ikaika kikoʻī o nā hui brazing ma mua o ka fusion welding, no laila hoʻohana pinepine ʻia nā ʻūhā no ka hoʻonui ʻana i ka hiki ke lawe;

2) He kiʻekiʻe loa nā koi no ka pae hoʻomaʻemaʻe o ka ʻili hui o ka mea hana brazing a me ka maikaʻi o ka hui ʻana o ka mea hana.

2. ʻO ke kumu a me ke kaʻina hana o ka brazing alumini

ʻO ke kumu o ka brazing alumini

ʻO ka maʻamau, i ka wā brazing, aia kahi kiʻi ʻoniʻoni oxide ma luna o ka ʻili o ka alumini a me ke alumini alumini, kahi e pale ai i ka pulu a me ke kahe ʻana o ka solder hoʻoheheʻe.No laila, i mea e hoʻokō ai i kahi hui brazing maikaʻi o ka weldment, pono e luku ʻia kēia ʻāpana o ke kiʻi ʻoniʻoni ma mua o ke kuʻi ʻana.I ka wā o ke kaʻina hana brazing, i ka wā e hiki ai ka mahana i ka mahana i makemake ʻia o ka flux, e hoʻomaka ana ka hoʻoheheʻe ʻana, a palahalaha ke kahe i hoʻoheheʻe ʻia ma ka ʻili o ka alumini e hoʻoheheʻe i ke kiʻi oxide i ka piʻi ʻana o ka mahana.Hoʻomaka ka hoʻoheheʻe ʻana o ka Ai-Si, a kahe i ke āpau e welded ma o ka neʻe ʻana o ka capillary, pulu a hoʻonui e hana i kahi hui.

ʻOiai ʻo nā loina brazing o nā radiators alumini he mea like, hiki ke hoʻokaʻawale ʻia i loko o ka brazing vacuum, air brazing a me Nocolok.ka hoʻopaʻa ʻana e like me ke kaʻina hana brazing.Eia kekahi mau hoʻohālikelike kikoʻī o kēia mau hana brazing ʻekolu.

Ma waena o nā kaʻina hana ʻekolu, ʻo Nocolok.ʻO ka brazing ke kaʻina kumu o ke kaʻina brazing radiator alumini.ʻO ke kumu o Nocolok.Hiki i ka brazing ke lilo i wahi kikowaena o ke kaʻina hana brazing radiator alumini ma muli o ka maikaʻi kuʻi ʻana o kēia huahana.A loaʻa iā ia nā hiʻohiʻona o ka hoʻohana ʻana i ka ikehu haʻahaʻa, ka hana kiʻekiʻe o ka hana ʻana, ka hopena liʻiliʻi o ke kaiapuni, a me ke kūpaʻa ikaika o ka corrosion.He ala brazing kūpono.

Nocolok.Kaʻina Hana Pahu

Hoomaemae

Aia nā hoʻomaʻemaʻe ʻokoʻa o nā ʻāpana a me ka hoʻomaʻemaʻe ʻana i nā cores radiator.I kēia manawa, ʻo ka mālama ʻana i ka mahana a me ka hoʻomaʻemaʻe ʻana o ka mea hoʻomaʻemaʻe a me ka mālama ʻana i ka mahana a me ka hoʻomaʻemaʻe ʻana o ka mea hoʻomaʻemaʻe i kahi waiwai kūpono ke kumu nui o ka hoʻomaʻemaʻe.Hōʻike ka ʻike hoʻomaʻemaʻe i ka mahana hoʻomaʻemaʻe o 40 ° C a i 55 ° C a me ka neʻe ʻana o ka mea hoʻomaʻemaʻe o 20% nā waiwai maikaʻi loa no ka hoʻomaʻemaʻe ʻana i nā ʻāpana radiator alumini.(E pili ana i ka mea hoʻomaʻemaʻe hoʻomaʻemaʻe kaiapuni alumini, waiwai pH: 10; pono e hōʻoia ʻia nā mea hoʻomaʻemaʻe o nā ʻano like ʻole a i ʻole ka pae pH ma mua o ka hoʻohana ʻana)

Inā lawa ka flux, hiki ke hoʻopaʻa ʻia ka mea hana me ka ʻole o ka hoʻomaʻemaʻe ʻana, akā ʻo ka hoʻomaʻemaʻe ʻana e hopena i kahi kaʻina hana i hoʻohui ʻia, hiki ke hōʻemi i ka nui o ka flux i hoʻohana ʻia a loaʻa i kahi huahana welded maikaʻi.ʻO ka maʻemaʻe o ka mea hana e pili pū i ka nui o ka uhi flux.

Kapu ʻana i ke kahe

ʻO ka pīpī ʻana i ka flux ma ka ʻili o nā ʻāpana alumini he hana koʻikoʻi ma Nocolok.ʻO ke kaʻina hana brazing, ka maikaʻi o ka flux spraying e pili pono i ka maikaʻi o ka brazing.No ka mea aia kahi kiʻiʻoniʻoni oxide ma ka ʻili o ka alumini.ʻO ke kiʻiʻoniʻoni oxide ma luna o ka alumini ka mea e keʻakeʻa ai i ka pulu ʻana o ka ʻili a me ke kahe ʻana o ka fiber hehee.Pono e hoʻoneʻe ʻia ka kiʻiʻoniʻoni oxide a hou ʻia e hana i kahi weld.

ʻO ke kuleana o ka flux: 1) E luku i ke kiʻi oxide ma ka ʻili alumini;2) E hoʻoikaika i ka pulu a me ka maʻalahi o ke kahe ʻana o ka solder;3) Kāohi i ka ʻili mai ka hoʻomaʻamaʻa hou ʻana i ka wā o ka hana brazing.Ma hope o ka pau ʻana o ka brazing, e hana ka flux i kahi kiʻiʻoniʻoni pale me ka hoʻopili ikaika ma ka ʻili o ka ʻāpana alumini.ʻAʻohe hopena maikaʻi ʻole o kēia papa kiʻiʻoniʻoni i ka hana o ka huahana, akā hiki iā ia ke hoʻonui nui i ka hiki o nā ʻāpana alumini e pale aku i ka corrosion o waho.

ʻO ka nui o ka flux i hoʻopili ʻia: I ka wā o ke kaʻina hana brazing, ka nui o ka flux i hoʻopili ʻia: maʻamau 5g o ka flux no ka mika square;He mea maʻamau ka 3g no ka mika square i kēia mau lā.

ʻO ke ala hoʻohui flux:

1) Nui nāʻano likeʻole: ka hoʻouluʻana i ka haʻahaʻa haʻahaʻa, ka'ōpala, ka hoʻouluʻana i ke kiʻekiʻe, ke kuʻiʻana, ka hoʻouluʻana i ka electrostatic;

2) ʻO ke ʻano maʻamau o ka hoʻohui ʻana i ka flux i ke kaʻina hana brazing ea (c AB) ʻo ia ka hoʻokuʻu ʻana;

3) ʻO ke kino a me nā waiwai kemika o ka flux e hana i ka pulupulu pulu ke koho mua;

4) Ma ke ao holoʻokoʻa, e like me nā helu helu: 80% hoʻohana i ka pulu pulu, 15% hoʻohana i ka pulu maloʻo, 5% koho koho a i ʻole ke kapa mua;

ʻO ka pulupulu pulu ke ʻano maʻamau o ka fluxing i ka ʻoihana a hāʻawi i nā hopena maikaʻi loa.

Hoʻomaloʻo

I mea e hōʻoiaʻiʻo ai i ka maikaʻi o nā ʻāpana brazing, pono e hoʻomaloʻo piha ʻia ka mea hana ma mua o ka brazing e hoʻoneʻe i ka wai mai ka uhi flux.ʻO ka mea koʻikoʻi i ka hoʻomaloʻo ʻana, ʻo ia ka mālama ʻana i ka mahana maloʻo a me ka wikiwiki mesh;inā haʻahaʻa loa ka mahana a i ʻole ka wikiwiki o ka mesh, ʻaʻole e maloʻo ke kumu, e hopena i ka emi ʻana o ka maikaʻi brazing a i ʻole desoldering.ʻO ka mahana maloʻo ma waena o 180 ° C a me 250 ° C.

Hoʻopaʻa

ʻO ka mahana o kēlā me kēia wahi i ka ʻāpana brazing, ka wikiwiki o ka ʻupena a me ka lewa o ka umu ahi e hoʻomalu i ka maikaʻi brazing.ʻO ka mahana wela a me ka manawa brazing ka hopena pololei i ka maikaʻi o ka huahana.ʻAʻole i manaʻo ʻia inā he kiʻekiʻe a haʻahaʻa paha ka mahana, he hopena maikaʻi ʻole ia i ka huahana, e like me ka hoʻohaʻahaʻa ʻana i ke ola lawelawe o ka huahana, ka hopena i ka wai ʻilihune o ka solder, a me ka hoʻonāwaliwali ʻana i ke kūpaʻa luhi o ka huahana;no laila, ʻo ka mālama ʻana i ka mahana a me ka manawa brazing ke kī i ke kaʻina hana.

ʻO ka lewa i loko o ka umu ahi he mea nui e pili ana i ka helu welding.I mea e pale ai i ka flux a me nā ʻāpana alumini mai ka oxidized e ka ea, ʻo ka wikiwiki o ka mesh ʻaʻole e hoʻoholo wale i ka lōʻihi o ka manawa brazing, akā e hoʻoholo pū i ka pono hana.Ke nui ka leo o ka radiator core, i mea e loaʻa ai ka wela kūpono no kēlā me kēia ʻāpana (pre-brazing zone, wela wela a me brazing zone) i ka wā o ka hana brazing.Pono e lohi ka wikiwiki o ka pūnaewele i hiki i ka mahana wela ke hiki i ka waiwai kaʻina hana maikaʻi loa.ʻO ka mea ʻē aʻe, inā liʻiliʻi ka nui o ka radiator core, pono e wikiwiki ka wikiwiki o ka pūnaewele.
