Huila Uila Uila Pu/PP Uila Hula Me/me ole ka Paa – ED4 SERIES

1. Ka waihoʻoluʻu o ka ea oxide kiʻiʻoniʻoni: pono ke kala ma hope o bluish, ʻaʻole ʻae ʻia nā stains a me kahi hapa o ka kiʻi ʻoniʻoni air oxide. Ma muli o ka ʻokoʻa o ka ʻili o ka ʻāpana like, a i ʻole nā ʻāpana me ka mālama wela ʻāpana a i ʻole ke kūlana wili uila, ʻae ʻia ka ʻokoʻa kala. Ma hope o ke kalapona kalapona a me nā ʻāpana kila kila kiʻekiʻe i ka uliuli, pono e loaʻa kahi kiʻi ʻoniʻoni ʻeleʻele ʻeleʻele symmetrical. ʻAe ʻia nā mea hoʻolei a me nā ʻāpana kalapona i loaʻa i ke silika he melemele a ʻeleʻele paha ma hope o ka huli ʻana i ka uliuli.

2. Ka ikaika compressive o ka ea oxide film: ʻO ka ea oxide film a me ka fusion nui compressive ikaika, e hamo ikaika me kahi lole maloʻo, a mai hōʻike i ke ʻano metala.

3. ʻO ka paʻa o ka kiʻiʻoniʻoni air oxide: Ke lilo nā ʻāpana i polū, e hoʻohana i ka 3% sodium thiosulfate solution e corrode no kahi o 30 kekona ma mua o ka hoʻohana ʻana i ka aila, ʻaʻole ʻae ʻia ka electroplating keleawe ma ka ʻili o nā ʻāpana. Eia nō naʻe, hiki ke loaʻa ka liʻiliʻi o nā ʻili keleawe ma nā kihi ʻoi, nā kihi a me nā kūlana wili.

4. Anti-corrosion o ka ea oxide kiʻiʻoniʻoni: corroded e 3% edible paakai solution no 3 hola me ka corrosion.

5. ʻO ka maʻalahi o nā ʻāpana a me ia: Ma hope o ka hoʻomaʻemaʻe ʻana, e hoʻoheheʻe i 1-2 kulu o ka solution alcohol phenolphthalein ma ka ʻāpana huahana. No ka laʻana, he ʻulaʻula ʻulaʻula ka waiʻona phenolphthalein, e hōʻike ana ʻaʻole maʻemaʻe ka hoʻomaʻemaʻe.
