Nā ʻano ʻāpana keleawe a me kā lākou hoʻohana?

Nā ʻāpana keleaweLoaʻa i ka plasticity maikaʻi loa a me ka ikaika kiʻekiʻe, ka machinability maikaʻi, maʻalahi ke kuʻi ʻana, a paʻa loa i ka corrosion maʻamau.ʻO ka ʻāpana keleawe he hui keleawe a me ka zinc, i kapa ʻia no kona kala melemele.ʻO kaʻoiaʻiʻo, he nui nā ʻano ʻāpana keleawe ma ka mākeke, e like me H96, H90, H85, H70, H68, a me nā mea ʻē aʻe.
kaula keleawe
1. Ua like ka hana o ka H90 me ka H96, aka, ua oi iki kona ikaika mamua o ko H96.Hiki ke uhi ʻia me ka metala a hoʻopaʻa ʻia me ka enamel.
Hoʻohana: ʻO nā paipu wai a me ka wai, nā mekala, nā hana noʻeau, nā kaula pahu, a me nā ʻāpana bimetallic.
2. He ikaika kiʻekiʻe ka ikaika o ke keleawe H85, ka plasticity maikaʻi, hiki ke kū i ka wela a me ke kaomi ʻana me ka maikaʻi, a he maikaʻi ke kuʻi ʻana a me ka pale ʻana i ka corrosion.
Hoʻohana: ʻO nā paipu hoʻoheheʻe a me ka wela, nā paipu siphon, nā paipu serpentine, a me nā mea hoʻoluʻu.
3. H96 keleawe kaula i oi aku ka ikaika ma mua o maemae keleawe, maikai thermal conductivity a me ka uila conductivity, kiʻekiʻe corrosion kū'ē i loko o ka lewa a me ka wai hou, a me ka maikai plasticity, oluolu i ke anu a me ka wela puʻe hana, oluolu e weld, forge a me ka tin-plated,ʻaʻohe stress Prone i ka corrosion māwae.
Hoʻohana: Hoʻohana ʻia ma ke ʻano he conduits, condensation pipes, radiator pipes, heat sink, kāʻei pahu wai kaʻa a me nā ʻāpana conductive i ka hana mīkini maʻamau.
4. H70 a me H68 keleawe i ka plasticity maikaʻi a me ka ikaika kiʻekiʻe, maikaʻi machinability, oluolu kuʻihao, paa loa i ka maʻamau corrosion, akā, prone i ka corrosion a me ka pohā.Hoʻohana nui ʻia ka H68 i ke keleawe maʻamau.Hoʻohui ʻia kekahi ʻano like ʻole, H68A me kahi liʻiliʻi o ka arsenic (As), hiki ke pale i ke keleawe mai ka dezincification a hoʻomaikaʻi i ka pale ʻana o ke keleawe.
Hoʻohana: ʻO ka hoʻopaʻa ʻana i ke anuanu paʻakikī a me nā ʻāpana kikoʻī hohonu, e like me nā pūpū radiator, conduits, bellows, pahu pahu pahu, gaskets, etc.
