ʻO nā kumu kaiapuni e pili ana i nā paneli i uhi ʻia i ke kala
Ke alo nei i nā ʻano ʻano uhi like ʻole, pehea mākou e koho ai?E ʻae mai iaʻu e hoʻolauna i kekahi mau mea kaiapuni e pili ana i ka hoʻohana ʻana i nā papa i uhi ʻia i ke kala.
1. Ka wela
He maʻalahi ka hoʻopili ʻana i ka ʻili i ka wela kiʻekiʻe, a maʻalahi ke ʻano corrosive e pili.He mea maʻalahi ke komo i loko o ka substrate, e hoʻonui ka oxygen i loko o ka wai i ke kiʻekiʻe kiʻekiʻe, a e piʻi ka nui o ka corrosion i kahi mahana.
2. Haʻahaʻa
ʻO ka ʻino o ka substrate ma ka ʻoki a me ka hoʻoponopono ʻana i ka pōʻino o ka papa i uhi ʻia i ka waihoʻoluʻu no ka corrosion electrochemical, a ʻaʻole maʻalahi ka haʻahaʻa haʻahaʻa e hoʻokumu i kahi pānaʻi corrosion (ie electrochemical circuit).
3, ʻO ka ʻokoʻa wela ma waena o ke ao a me ka pō
ʻO ka ʻokoʻa wela nui he maʻalahi ke condense, e hana ana i kahi kūlana galvanic corrosion ma luna o ka metala ʻole.Eia kekahi, ʻo ka ʻokoʻa wela nui e alakaʻi i ke anuanu a me ka wela o ka deformation o ka uhi, kahi e hoʻolōʻihi ai i ka ʻelemakule a me ka looseness o ka uhi ʻana, a e komo maʻalahi ka mea corrosive waho i loko o ka substrate.
4. Ka manawa a me ka ikaika o ka lā
Hoʻopili ka orientation a me ka slope i ka lōʻihi o ka lā a no laila ka lōʻihi o ka uhi.Hoʻopili pū ka slope i ka manawa hoʻonā o ka media corrosive a i ʻole ka lepo ma ka pā kila.ʻO ka lā ka nalu electromagnetic, i māhele ʻia i nā kukuna gamma, nā kukui X, nā kukui ultraviolet, nā kukui ʻike ʻia, nā kukui infrared, nā microwave a me nā hawewe lekiō e like me ko lākou ikaika a me ka pinepine.He haʻahaʻa ka ikehu o nā nalu a me nā hawewe lekiō a ʻaʻole pili pū me ka mea.ʻO ka infrared kekahi ʻano uila haʻahaʻa.Hiki iā ia ke kikoo a hoʻopōloli paha i nā paʻa kemika o nā mea, akā ʻaʻole hiki ke wāwahi.Hāʻawi ka mālamalama ʻike i nā kala momona a pau.ʻO ka UV spectrum he pāhawewe kiʻekiʻe, ʻoi aku ka nui o ka mana luku ma mua o ka spectrum haʻahaʻa.E like me kā mākou ʻike, ʻo nā wahi ʻeleʻele o ka ʻili a me ka maʻi maʻi ʻili ma muli o nā kukuna ultraviolet o ka lā.Pēlā nō, hiki i ka UV ke uhaki i nā paʻa kemika o nā mea, e wāwahi ai.Pili kēia i ka lōʻihi hawewe UV a me ka ikaika paʻa kemika o ka mea.Loaʻa i nā kukui X nā hopena kuʻuna.Hiki i nā kukuna Gamma ke uhaki i nā paʻa kemika o nā mea a hoʻohua i nā iona manuahi.He mea make kēia i nā mea olaola.ʻO ka mea pōmaikaʻi, he kakaikahi kēia mau kukuna i ka lā.No laila, hiki ke ʻike ʻia mai luna aʻe e pili ana ka manawa o ka lā a me ka ikaika i ka paʻa o ka hale uhi, ʻoi loa ma nā wahi me nā kukuna ultraviolet ikaika.
5. Ka ua a me ka waiʻona
He mea ʻino ʻole ka ua acidity i ka pale ʻana i ka corrosion.Eia nō naʻe, ʻelua ka hopena o ka ua.No nā panela pā a me nā pā hale me nā pali nui, hiki i ka ua ke hoʻomaʻemaʻe i ka ʻili o nā pā kila a holoi i nā huahana corrosion.Eia nō naʻe, no nā panela o ka hale me nā pali haʻahaʻa a me nā wahi me ka wai maikaʻi ʻole, nui ka ua e Maʻalahi ka hoʻonui ʻana i ka corrosion.
6. Ka makani a me ka māmā holo
ʻO ka hopena o ka makani a me ka wikiwiki o ka makani e like me ka wai, a hele pinepine lākou.He ho'āʻo ia no ka hoʻopili ʻana i nā mea, no ka mea, ʻo ka makani ka mea e hemo ai ka pilina a komo ka wai ua i loko o ka hale.
7. Ka ʻinoʻino a me ka paʻapū
No ka laʻana, loaʻa i nā ion chloride, sulfur dioxide, a me nā mea ʻē aʻe ka hopena wikiwiki i ka corrosion, a ʻo kēia mau sediment e ulu nui ʻia ma kahakai a ma nā wahi me ka haumia ʻoihana koʻikoʻi (e like me nā mea kanu mana, smelters, etc.).
