ʻO ka hiʻohiʻona maikaʻi o kahi huahana kahi mea nui o ka maikaʻi sensory. ʻO ka maikaʻi o ka hiʻohiʻona e pili ana i nā mea maikaʻi o ke ʻano o ka huahana, ke kala kala, luster, pattern, a me nā ʻike ʻike ʻē aʻe.
ʻIke loa, ʻo nā hemahema a pau e like me nā puʻupuʻu, nā ʻōpala, nā indentations, scratches, rust, mold, bubbles, pinholes, pit, surface cracks, delamination, wrinkles, etc. Eia kekahi, nui nā hiʻohiʻona hiʻohiʻona o ka huahana e pili pono i ka hana o ka huahana, ke ola, a me nā mea ʻē aʻe. Loaʻa i nā huahana me nā ʻili paheʻe ke kūpaʻa ʻana i ka ʻōpala, ka liʻiliʻi haʻahaʻa haʻahaʻa, ke kūpaʻa maikaʻi a me ka hoʻohana ʻana i ka ikehu.
ʻO ka loiloi o ka maikaʻi o ka hiʻohiʻona huahana he ʻano kumuhana. I mea e hoʻoholo ai i nā manaʻo e like me ka hiki, ua hoʻohana pinepine ʻia nā ʻano loiloi e pili ana i ka nānā ʻana i ka maikaʻi o nā huahana ʻoihana.
(1)Keʻano hui laʻana maʻamau. E koho mua i nā hōʻailona kūpono a kūpono ʻole e like me nā laʻana maʻamau, kahi i loaʻa ai nā hemahema like ʻole me nā pae like ʻole o ka paʻakikī.
Hiki ke nānā pinepine ʻia ka laʻana maʻamau e nā mea nānā he nui (nā loiloi) a hiki ke nānā ʻia nā hopena nānā. Ma hope o ke kālailai ʻana i nā hualoaʻa helu, hiki ke hoʻoholo i nā ʻāpana hemahema i kuhikuhi pono ʻole ʻia; ʻAʻole maopopo i nā mea nānā i nā kūlana; ʻO nā mea nānā i nele i ka hoʻomaʻamaʻa pono a me nā mākau ʻike.
(2)ʻano nānā kiʻi.Ma o ke kiʻi, hiki ke hōʻike ʻia nā hiʻohiʻona kūpono a me nā palena kīnā ʻae ʻia e nā kiʻi, a hiki ke hoʻohana ʻia nā kiʻi maʻamau o nā hemahema like ʻole no ka nānā hoʻohālikelike.
(3)ʻano hoʻonui hemahema.E hoʻohana i ke aniani hoʻonui a i ʻole ka projector e hoʻonui i ka ʻili o ka huahana a ʻimi i nā hemahema ma ka ʻili i ʻike ʻia, i mea e hoʻoholo pono ai i ke ʻano a me ka paʻakikī o nā hemahema.
(4)Keʻano mamao nalowale.E hele i ka pūnaewele hoʻohana huahana, e nānā i nā kūlana hoʻohana o ka huahana, a nānā i ke kūlana hoʻohana o ka huahana. A laila e hoʻohālikelike i nā kūlana hoʻohana maoli o ka huahana, a kuhikuhi i ka manawa kūpono, ka mamao nānā, a me ke kihi e like me nā kūlana nānā no ka nānā ʻana. No ka laʻana, inā ʻaʻole hiki ke ʻike ʻia kahi kīnā o kekahi huahana i loko o 3 kekona mai kahi mamao o hoʻokahi mika, manaʻo ʻia ʻo ia ke kūpono, inā ʻaʻole i manaʻo ʻia ʻaʻole kūpono. ʻOi aku ka maʻalahi o kēia ʻano hana ma mua o ka hoʻonohonoho ʻana i nā mea maʻamau i kēlā me kēia mea e pili ana i nā ʻano like ʻole a me ka paʻakikī o nā hemahema, a me ka nānā ʻana i kēlā me kēia mea.
Laʻana: ʻO ka nānā ʻana i ka maikaʻi o ke ʻano o ka uhi galvanized ma nā ʻāpana.
① Nā koi o ka hiʻona.ʻO ka hiʻohiʻona maikaʻi o ka papa galvanized e loaʻa i nā ʻano ʻehā: kala, kūlike, nā hemahema ʻae ʻia, a me nā hemahema ʻae ʻole.
kalakala. ʻO kahi laʻana, pono ka papa galvanized i kahi hina hina me kahi kala beige liʻiliʻi; Ma hope o ka ʻike ʻia ʻana i ka mālamalama, e lilo ka papa galvanized i keʻokeʻo kālā me kahi ʻulaʻula a me kahi ʻōniʻoniʻo o ka uliuli māmā; Ma hope o ka hoʻomaʻamaʻa ʻana i ka phosphate, pono e ʻāhinahina ka papa galvanized i ka hina hina.
Kaulike. Pono ka papa galvanized e loaʻa i kahi crystallized maikaʻi, ʻaʻahu, a me ka ʻili mau.
Nā hemahema ʻae ʻia. Eia kekahi laʻana, nā kaha wai liʻiliʻi; Nā hōʻailona paʻa liʻiliʻi ma ka ʻili o nā ʻāpana koʻikoʻi; Aia nā ʻokoʻa liʻiliʻi o ka waihoʻoluʻu a me ka ʻōlinolino ma ka ʻāpana like.
ʻAʻole ʻae ʻia nā hemahema. No ka laʻana, ʻohu, ʻili, ʻā, nodulation, a me ka lua o ka uhi; Dendritic, spongy, a me nā uhi ʻoniʻoni; Paakai holoi ole ia, etc.
② Laʻana no ka nānā ʻana.No nā'āpana koʻikoʻi, nā'āpana koʻikoʻi, nā'āpana nui, a me nā'āpana maʻamau me ka nui o ka hui ma lalo o 90 mau'āpana, pono e nānāʻia ka helehelena 100% e hoʻopau i nā huahana kūponoʻole; No nā ʻāpana maʻamau me ka nui o ka puʻupuʻu i ʻoi aku ma mua o 90 mau ʻāpana, pono e hoʻokō ʻia ka nānā ʻana i ka laʻana, me kahi pae nānā nui o II a me kahi pae kiʻekiʻe o 1.5%. Pono e hoʻokō ʻia ka nānā ʻana e like me ka hoʻolālā sampling nānā maʻamau i kuhikuhi ʻia ma ka Papa 2-12. Ke ʻike ʻia kahi puʻupuʻu like ʻole, ʻae ʻia e hana i kahi 100% nānā ʻana o ka pūʻulu, hoʻopau i nā huahana like ʻole, a waiho hou no ka nānā ʻana.
③ Nā ʻano nānā ʻike a me ka loiloi maikaʻi.ʻO ka nānā ʻana i nā hiʻohiʻona ke ala nui no ka nānā ʻana i nā hiʻohiʻona, a inā pono, hiki ke hoʻohana ʻia ke aniani hoʻonui 3-5 mau manawa no ka nānā ʻana. I ka wā o ka nānā ʻana, e hoʻohana ʻia ke kukui hoʻopuehu maoli a i ʻole ke kukui uila keʻokeʻo me ka ʻike ʻole ʻia. ʻAʻole emi ka mālamalama ma mua o 300 Lux, a ʻo ka mamao ma waena o nā ʻāpana a me nā maka kanaka he 250 mm. Inā he 100 ka nui o ka hui, hiki ke koho ʻia kahi laʻana o 32 mau ʻāpana; Ma o ka nānā maka ʻana i kēia mau ʻāpana he 32, ua ʻike ʻia he ʻelua o lākou ka pohu ma ka uhi a me nā kaha kuni. Ma muli o ka nui o nā huahana like ʻole he 2, ua manaʻo ʻia kēia ʻāpana o nā ʻāpana ʻaʻole kūpono.
