Ka hoʻoheheʻe ʻana i ke keleawe a me nā mea hao keleawe

1. Mea hoʻoheheʻe

(1) Ua hōʻike ʻia ka ikaika o ka hoʻopaʻa ʻana o kekahi mau mea hoʻoheheʻe i hoʻohana pinepine ʻia no ke keleawe a me ka brazing keleawe ma ka papa 10.

Papa 10 ikaika o nā hui keleawe a me ke keleawe i hoʻoheheʻe ʻia

I ke kāpili ʻana i ke keleawe me ka solder kēpau tin, hiki ke koho ʻia ka flux brazing non corrosive e like me ka hopena rosin alcohol a i ʻole ka rosin hana a me ka zncl2+nh4cl aqueous solution. Hiki ke hoʻohana ʻia ka mea hope no ka brazing keleawe, keleawe a me ke keleawe beryllium. I ke kāpili ʻana i ke keleawe alumini, ke keleawe alumini a me ke keleawe silicon, hiki ke lilo ka flux brazing i ka hopena zinc chloride hydrochloric acid. I ke kāpili ʻana i ke keleawe manganese keʻokeʻo, hiki ke lilo ka mea hoʻokomo i ka hopena phosphoric acid. Hiki ke hoʻohana ʻia ka hopena zinc chloride aqueous ma ke ʻano he flux i ka wā e kāpili ai me ka metala hoʻopihapiha e pili ana i ke kēpau, a hiki ke hoʻohana ʻia ka flux fs205 i ka wā e kāpili ai me ka metala hoʻopihapiha e pili ana i ka cadmium.

(2) I ka wā e hoʻopili ai i ke keleawe me nā metala hoʻopihapiha a me nā fluxes, hiki ke hoʻohana ʻia nā metala hoʻopihapiha kālā a me nā metala hoʻopihapiha keleawe phosphorus. ʻO ka solder kālā ka solder paʻakikī i hoʻohana nui ʻia ma muli o kona wahi heheʻe haʻahaʻa, ka hiki ke hana maikaʻi, nā waiwai mechanical maikaʻi, ka conductivity uila a me ka thermal. No ka workpiece e koi ana i ka conductivity kiʻekiʻe, pono e koho ʻia ka solder b-ag70cuzn me ka nui o ke kālā. No ka brazing vacuum a i ʻole ka brazing i loko o ka umu lewa pale, pono e koho ʻia ka b-ag50cu, b-ag60cusn a me nā mea brazing ʻē aʻe me ka ʻole o nā mea volatile. ʻO nā metala hoʻopihapiha Brazing me ka haʻahaʻa o ke kālā he haʻahaʻa ke kumukūʻai, he kiʻekiʻe ka mahana brazing a me ka paʻakikī haʻahaʻa o nā hui brazed. Hoʻohana nui ʻia lākou no ka brazing keleawe a me nā mea hao keleawe me nā koi haʻahaʻa. Hiki ke hoʻohana ʻia nā metala hoʻopihapiha keleawe phosphorus a me ke keleawe phosphorus kālā no ka brazing o ke keleawe a me kāna mau mea hao keleawe. I waena o lākou, he maikaʻi ka fluidity o b-cu93p a hoʻohana ʻia no ka brazing ʻana i nā ʻāpana ʻaʻole i kau ʻia i ka ukana hopena ma nā ʻoihana Electromechanical, mea hana a me nā hana hana. ʻO ka hakahaka kūpono loa he 0.003 ~ 0.005mm. ʻOi aku ka paʻakikī a me ka conductivity o nā metala hoʻopihapiha keleawe phosphorus kālā (e like me b-cu70pag) ma mua o nā metala hoʻopihapiha keleawe phosphorus. Hoʻohana nui ʻia lākou no nā hui uila me nā koi conductivity kiʻekiʻe. Hōʻike ka Papa 11 i nā waiwai hui o kekahi mau mea brazing maʻamau i hoʻohana ʻia no ka brazing keleawe a me ke keleawe.

Papa 11 nā waiwai o nā hui keleawe a me nā keleawe i hoʻoheheʻe ʻia
