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 kahi huahana, ka leo kala, ka nani, ke ʻano, a me nā mea ʻē aʻe i ʻike maka.ʻIke loa, ʻo nā hemahema a pau e like me ka puʻu, abrasions, indentations, scratches, rust, mold, bubbles, pinholes, pitting, surface cracks, delamination, wrinkles, etc.Eia kekahi, he nui nā kumu maikaʻi o nā hiʻohiʻona huahana e hoʻopili pololei i ka hana huahana, ola 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 ʻana i ka maikaʻi o ka hiʻohiʻona o ka huahana aia kekahi 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)Kaʻina 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 nā 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 kīnā ʻaʻole i wehewehe pono ʻia;ʻAʻole maopopo i nā mea nānā i nā kūlana;ʻO nā mea nānā i nele i ka hoʻomaʻamaʻa pono a me ka hiki ke ʻike.
(2)ʻano nānā kiʻi.Ma o ke kiʻi ʻana, hiki ke hōʻike ʻia ke ʻano 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.Inā ʻike ʻia ka hemahema o kekahi huahana, ʻoiai ʻaʻole i ʻike ʻia i loko o 3 kekona mai kahi mamao o hoʻokahi mika, ua manaʻo ʻia he kūpono, inā ʻaʻole i manaʻo ʻia ʻaʻole kūpono.ʻOi aku ka maʻalahi o kēia ʻano hana ma mua o ka hoʻonohonoho ʻana i nā kūlana a me ka nānā ʻana i kēlā me kēia mea e pili ana i nā ʻano like ʻole a me ka paʻakikī o nā hemahema.
Laʻana: ʻO ka nānā ʻana i ka maikaʻi o ke ʻano o ka uhi galvanized ma nā ʻāpana.
①Nā koi o ka hiʻona.ʻO ka hiʻohiʻona hiʻohiʻona o ka uhi galvanized e loaʻa i nā ʻano ʻehā: ka waihoʻoluʻu, ka like ʻole, nā hemahema ʻae ʻia, a me nā hemahema ʻae ʻole.
kalakala.ʻO kahi laʻana, ʻo ka papa galvanized e pono ke kala hina hina me kahi hue beige liʻiliʻi;Ma hope o ka ʻike ʻia ʻana i ka mālamalama, ʻike ʻia ka papa galvanized e like me ke keʻokeʻo kālā me kahi ʻōlinolino 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.
ʻAe i nā hemahema.No ka laʻana, nā ʻili wai liʻiliʻi;He mea koʻikoʻi loa nā ʻāpana, a he mau kaha liʻiliʻi ma ka ʻili;Aia nā ʻokoʻa liʻiliʻi o ka waihoʻoluʻu a me ka ʻōlinolino ma ka ʻāpana like.
ʻAʻole ʻae ʻia nā hemahema.No ka laʻana: blistering, peeling, kuni, nodulation, a me ka lua o ka uhi;Dendritic, sponge like, a me nā ʻili ʻoniʻoni;Paakai maemae ole, etc.
②Laʻana no ka nānā ʻana.No nā ʻāpana koʻikoʻi, nā ʻāpana koʻikoʻi, nā ʻāpana nui, a me nā ʻāpana maʻamau me ka nui o ka puʻupuʻu ma lalo o 90, pono e nānā ʻia ka hiʻohiʻona 100% a pono e wehe ʻia nā huahana like ʻole;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 loaʻa kahi pūʻulu kūpono ʻole, ʻae ʻia e nānā i ka pūʻulu 100%, wehe i nā huahana kūpono ʻole, a waiho hou no ka nānā ʻana.
③Nā 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 pālahalaha maoli a i ʻole ke kukui uila keʻokeʻo me ka ʻole o ka noʻonoʻo ʻana, me ka hoʻomālamalama ʻana ʻaʻole i emi iho ma mua o 300 lux, a ʻo ka mamao ma waena o nā ʻāpana a me ka maka kanaka he 250 millimeters.
Inā he 100 ka nui o ka pūʻulu, hiki ke unuhi 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.ʻOiai he 2 ka nui o nā huahana like ʻole, ua hoʻoholo ʻia ʻaʻole kūlike kēia pūʻulu o nā ʻāpana.
