ʻO ke koho waiwai no nā keʻena hoʻomalu e pili pono i ko lākou pale, paʻa, a me nā hiʻohiʻona pili. Hoʻokaʻawale ʻia lākou i loko o nā ʻāpana:
1. Metala
- Ke kila kila: Corrosion-kū'ē a me ka oxidation-kū'ē, kūpono no nā kaiapuni haʻahaʻa, nā ʻoihana kemika, a i ʻole ka hana meaʻai, akā ma ke kumu kūʻai kiʻekiʻe.
- Ke kila kalapona: Maikaʻi a kūpono, me ka ikaika mechanical kiʻekiʻe, pono ka mālama ʻana i ka ʻili (e like me ka pulu ʻana i ka plastic) e pale ai i ka ʻōpala a hoʻohana mau ʻia i nā kaiapuni ʻoihana.
- Aluminum Aluminum: Māmā a maikaʻi ka wela, kūpono i nā polokalamu kelepona a i ʻole ka -mahanahana kiʻekiʻe, akā hāʻawi iki i ka palekana.
2. ʻEnekinia plastik
- ABS/polycarbonate: Hoʻopuʻu maikaʻi loa, māmā, a me ka pale kemika, kūpono no nā hale keʻena keʻena, nā hale lapaʻau, a i ʻole ka hoʻohana ʻana i waho (koi i ka pale UV), akā me ka haʻahaʻa haʻahaʻa.
3. Nā mea hoʻohuihui
- E like me ka fiberglass reinforced plastic (FRP), hāʻawi i ka pale ʻana i ka corrosion a me ka ikaika mechanical, akā ʻoi aku ke kumukūʻai a hoʻohana pinepine ʻia i nā kaiapuni kūikawā (e like me nā moku a me nā petrochemical).
Koho Koho:
- Kaiapuni: Pono ke pale ʻana i ka ʻōpala no ka hoʻohana ʻana i waho (koho i ke kila kila/FRP); pono ka wela no ka -kaiapuni ki'eki'e (koho i ka alumini alumini).
- Ka helu palekana: Paipai ʻia nā keʻena metala no IP54 a i luna, ʻoiai ʻo nā keʻena plastik i hoʻopaʻa ʻia he koho no IP65. Kumukūʻai: Hāʻawi ke kila kalapona i ka waiwai maikaʻi loa no ke kālā, ʻoiai ua kūpono ke kila kuhiliʻole a me nā mea i hui ʻia no ka lōʻihi -paʻa.
Eia kekahi, pono e noʻonoʻo ʻia ke ʻano o ke kau ʻana (ka -pā, ka papahele-kū) a me nā pono pale electromagnetic (e laʻa, hiki i nā keʻena metala ke pale aku i ka hoʻopilikia ʻana).
