He aha kā mākou e ʻike ai e pili ana i nā "Tinning Rods"

No ka hoʻomākaukau ʻana a me ka maikaʻi o nā koʻokoʻo tinning

ʻO ke koʻokoʻo tin, e like me ka inoa i hōʻike ʻia he rod solder, ua kapa ʻia ʻo ia he ʻoihana lāʻau tin. Hoʻohana nui ʻia no ka hoʻoheheʻe ʻana i ka nalu a me ka hoʻoheheʻe ʻia ʻana, ʻo ia ka ʻai nui loa o nā ʻano solder uila; Hoʻohana ʻia kahi mea liʻiliʻi no ka hoʻoheheʻe ʻana i ka lapalapa ahi a i ʻole ka hao hao ʻana o nā ʻāpana kūkulu nui a me nā welds lōʻihi. ʻO ia ka mea koʻikoʻi a koʻikoʻi e pili ana i nā mea uila a me nā huahana uila a ʻo ka hoʻohana makahiki honua ma kahi o 100,000 tons.

He maʻalahi ke kaʻina hana hoʻomākaukau o ka pahu tin, e like me ka hoʻopaʻa ʻana, ka hoʻoheheʻe ʻana a me ka hoʻolei ʻana, a ʻo ke ʻano o ka oxidation a me ka ʻike o ka metala a me nā mea haumia ʻole. ʻO ka wela hoʻoheheʻe a me ka mahana hoʻoheheʻe ʻana he hopena nui i ka maikaʻi o ka tin. He mea maʻalahi ka hoʻomākaukau ʻana i nā ʻāpana tin a he haʻahaʻa ka paepae ʻenehana, no laila ua ikaika loa ka hoʻokūkū. ʻO ke kumu kūʻai o kēia manawa ke hoʻohui wale nei i kahi uku hana liʻiliʻi i ke kumukūʻai o nā mea maka. I ka manawa e loli nui ai ke kumukūʻai o nā mea maka i ka wā pōkole, hiki ke hoʻopau ʻia ka waiwai liʻiliʻi, a i ʻole ke poho.

ʻO nā koi nui no ka maikaʻi o ka pahu tin e like me kēia:

(1) He laumania ka ili o ka pahu;

(2) Ka wai maikaʻi a me ka wettability i ka wā wili;

(3) ʻO nā mea mechanical maikaʻi;

(4) A hui solder malamalama;

(5) Liʻiliʻi ke koena oxidation.

ʻO nā hemahema maʻamau ma luna o ka ʻili o ka ʻili, he mau kiko pua a me nā ʻōhū. Hoʻokumu ʻia kēia mau hemahema e ka hana hana a me ka hoʻohana ʻana i nā mold. No ka laʻana, ʻaʻohe ʻili ʻili i ka wā o ka hana ʻana, ʻaʻole maikaʻi ka ʻōnaehana hoʻoluʻu, a ʻaʻole maʻalahi nā ʻōpala, e alakaʻi i nā pilikia ma luna. ʻO ke kumu o ka pehu e pili ana i ka wā i hana ʻia ai. Lawe nā limahana hana i ka pahu pahu, ʻaʻole e hoʻohana pololei i ka lima, e hoʻopilikia ka makū i ka lima i ka ʻōlinolino o ka pahu tin, ka mana o ka tin bar o ka hoʻohana maikaʻi ʻana i ka pepa plastik, hiki iā lāua ke ʻike i ka ʻōlinolino, ʻaʻole pulu. Ke lōʻihi ka manawa o ka waiho ʻana a i ʻole ka pulu ʻana o ka wahi e waiho ai, aia kahi papa o ka oxide ma luna o ka ʻili o ka pahu tin, kahi e hoʻopau ai ka ʻōlinolino o ka pahu pahu, akā liʻiliʻi ka hopena i ka hopena hoʻohana. .

ʻO ka hoʻokaʻawale ʻana o nā ʻōpala tin:

Hoʻokaʻawale ʻia nā ʻōpala tin e ka mālama ʻana i ke kaiapuni, e komo pū ana me nā pahu pahu alakaʻi a me nā pahu pahu pahu ʻole.

I kēia manawa, ʻo ka mea maʻamau i hoʻohana ʻia i ke kēpau me ke kēpau ʻole, ʻo ia ka: tin copper lead-free tin strip (Sn99.3Cu0.7), tin silver copper lead-free tin strip (Sn96.5Ag3.0Cu0.5), 0.3 silver lead- ʻāʻī pīni manuahi (Sn99Ag0.3Cu0.7), ʻano kīʻaha kiʻekiʻe ke alakaʻi ʻole (SnSb).

ʻO ka mea hoʻohana maʻamau i hoʻohana ʻia i ka electrode lead tin electrode: 63/37 solder bar (Sn63/Pb37), 60/40 solder bar (Sn60/Pb40) a me ka wela kiʻekiʻe solder bar (400 degere ma luna o ke kuʻi ʻana).

Ma waho aʻe o nā mea nui o ka tin, ke kēpau, ke keleawe, ke kālā, loaʻa pinepine i kahi liʻiliʻi o nā mea ʻē aʻe, e like me ka nickel, antimony, bismuth, in, rare earth a pēlā aku.

ʻO kēia mau mea ʻeleʻele micro i loko o ka pahu tin he mana nui i nā ʻano kino a me nā ʻano mechanical o ka pahu tin: hiki i ka bismuth ke hoʻemi i ka wela hoʻoheheʻe ʻana o ka pahu tin a hoʻomaikaʻi i ka pulu a hoʻolaha ʻana i ka waiwai, akā ʻo ka nui o ka bismuth e hōʻemi i ke ola luhi a me ka plasticity o ka solder. nā hui, a ʻo ka nui kūpono o ka bismuth ma kahi o 0.2 ~ 1.5%. Hiki iā Ni ke hoʻomaikaʻi i nā waiwai mechanical a me ke ola luhi o nā hui solder ma ka hoʻololi ʻana i ka microstructure a hoʻomaʻemaʻe i ka palaoa. I ka hoʻolālā ʻōnaehana o ka haku mele mele, manaʻolana ka mea hoʻolālā e hiki ke loaʻa i ka pahu tin i kahi kaulike maikaʻi loa i nā ʻano like ʻole o ka hana, e like me ka hana welding, ka wela hoʻoheheʻe, ka ikaika, ka plasticity a me ke ola luhi, etc.

Inā makemake ʻoe i nā huahana tungsten carbide a makemake ʻoe i ka ʻike hou aku a me nā kikoʻī, hiki iā ʻoe ke CONTACT US ma ke kelepona a i ʻole ka leka uila ma ka hema, a i ʻole SEND US MAIL ma lalo o kēia ʻaoʻao.
