wehewehe:
Hoʻohana ʻo Bronze Powder i ke keleawe, zinc ma ke ʻano he kumu kumu / mea waiwai, ma o ka hoʻoheheʻe ʻana, ka pauka ʻōpala, ka wili pōleʻa a me ke kaʻina hana polishing o ka pauka metala liʻiliʻi liʻiliʻi, i kapa ʻia hoʻi ka pauka keleawe zinc alloy, i kapa ʻia ʻo ka pauka gula.
Nā hiʻohiʻona:
1.Bronze Powder a me ka hana ʻana o ka hue
Wahi a nā ʻano hana like ʻole, hiki i ka ʻili keleawe ke hōʻike i ka ʻulaʻula, ke gula, keʻokeʻo a i ʻole ka poni.ʻO nā ʻokoʻa zinc ʻokoʻa e hana i ka pauda keleawe i ka hue ʻokoʻa.Loaʻa ka zinc ma lalo o 10% e hoʻopuka i ka hopena gula pale, i kapa ʻia he gula pale;ʻO 10% -25% e hoʻopuka i ka hopena gula māmā maikaʻi, i kapa ʻia ʻo ke gula pale momona;ʻO 25% -30% e hoʻopuka i ka hopena gula māmā, i kapa ʻia he gula waiwai.
2.Micro-structure a me ka mahele nui o ka mahele o ka pauda keleawe
ʻO nā ʻāpana pauda keleawe he ʻano palaki, ma lalo o ka nānā ʻana o ka scanning electron microscopy, ʻaʻole maʻamau ka nui o nā flakes, a ʻo kona ʻaoʻao he ʻano zigzag, ʻo kekahi poʻe maʻamau.Hiki ke ho'onohonoho like 'ia me nā mea pena.
3.Bronze pauda optical waiwai
Loaʻa i ka pauka keleawe ka hopena dissimulation kala ma muli o ke kihi, pili ia i ka maʻalahi o ka ʻili metala.ʻO ka Micro-structure, ka mānoanoa o ka uhi ʻana a me ka hāʻawi ʻana i ka nui o nā ʻāpana he mea koʻikoʻi e hoʻoikaika i ka nani o ka paʻi gula.
