Noiʻi ma ka pale ʻana i ke ahi o nā mea kaʻa a me nā ʻano noi o nā olonā pale ahi i nā kaʻa
Me ka wikiwiki o ka ulu ʻana o ka ʻoihana kaʻa, ua lilo nā kaʻa—i hoʻohana ʻia no ka hele ʻana i ka hana a i ʻole ka lawe ʻana i nā waiwai—i mea hana pono ʻole i ke ola o kānaka. ʻOiai ke hāʻawi nei nā kaʻa i ka maʻalahi, hoʻopilikia pū lākou i ka palekana, e like me nā ulia kaʻa a me ke kuni koke ʻana. Ma muli o ka wahi paʻa a me nā mea i loko e lapalapa ana, i ka wā e puka mai ai ke ahi i loko o ke kaʻa, he mea paʻakikī ke kāohi, e hoʻoweliweli ana i ke ola a me ka waiwai o nā mea holo. No laila, ʻo ka palekana ahi i loko o nā kaʻa he mea nui ia no nā mea hoʻohana.
Ma keʻano laulā, hiki ke hoʻokaʻawale ʻia nā kumu o ke ahi i nā kaʻa i:
(1) Nā mea e pili ana i ke kaʻa, me nā hewa uila, nā liki wahie, a me ka haʻalulu mīkini i hoʻokumu ʻia e nā hoʻololi kūpono ʻole, nā hoʻonohonoho ʻana, a i ʻole ka mālama ʻana.
(2) Nā kumu o waho, e like me nā kuʻi ʻana, nā hiolo ʻana, ke ahi ʻana, a i ʻole nā kumu hoʻā ahi i mālama ʻole ʻia.
ʻO nā kaʻa ikehu hou, i lako me nā pila mana kiʻekiʻe-ikehu, ua maʻalahi loa i ke ahi ma muli o nā kaapuni pōkole i hoʻokumu ʻia e nā ulia, nā punctures, ka holo ʻana o ka wela mai nā mahana kiʻekiʻe, a i ʻole ke au nui i ka wā o ka hoʻouka wikiwiki ʻana.
01 Noiʻi ma ka pale ʻana i ke ahi o nā mea kaʻa
Ua hoʻomaka ke aʻo ʻana i nā mea pale ahi i ka hopena o ke kenekulia 19 ma ʻAmelika Hui Pū ʻIa. Me ka holomua o ka ʻenehana i nā makahiki i hala iho nei, ua loaʻa nā koi hou no ka noiʻi ʻana i ka pale ahi o nā mea o loko o ke kaʻa, ʻo ia hoʻi ma nā wahi aʻe:
ʻO ka mea mua, ka noiʻi kumumanaʻo e pili ana i ka pale ʻana i ka lapalapa. I nā makahiki i hala iho nei, ua kau nui nā mea noiʻi ma Kina i ke aʻo ʻana i nā ʻano hana puhi o nā ʻano olonā a me nā plastics like ʻole, a me ka hoʻohana ʻana i nā mea pale lapalapa.
ʻO ka lua, ka hoʻomohala ʻana i nā mea pale ahi. I kēia manawa, nui nā ʻano mea pale ahi e hoʻomohala ʻia nei. Ma ka honua holoʻokoʻa, ua hoʻopili pono ʻia nā mea e like me PPS, fiber kalapona, a me ke aniani ma nā ʻoihana like ʻole.
ʻO ke kolu, ka noiʻi ʻana i nā lole pale ahi. He maʻalahi ka hana ʻana i nā lole pale ahi a he kūpono loa. ʻOiai ua hoʻomohala maikaʻi ʻia nā lole pulupulu pale ahi, ua kaupalena ʻia ka noiʻi ʻana i nā lole pale ahi ʻē aʻe ma Kina.
ʻO ka hā, nā lula a me nā ʻano hoʻāʻo no nā mea pale ahi.
Hiki ke hoʻokaʻawale nui ʻia nā mea o loko o ke kaʻa i ʻekolu mau ʻāpana:
- ʻO nā mea i hana ʻia i ka fiber (e like me nā noho, nā kāpeti, nā kāʻei noho) - nā mea i hoʻohana nui ʻia a pili pono me nā ohua.
- Nā mea i hana ʻia ma ka palakiko.
- Nā mea i hana ʻia me ka laholio.
ʻO nā mea i hana ʻia me ka fiber, he mea hiki ke lapalapa a kokoke i nā mea holo, he mau pilikia nui ia i ka wā e ahi ai. Eia kekahi, aia kekahi mau ʻāpana kaʻa, e like me nā pila a me nā mīkini, kokoke i nā mea lole, e hoʻonui ana i ka likelika o ka laha ʻana o ke ahi. No laila, he mea nui ke aʻo ʻana i ka pale ʻana i ka lapalapa o nā mea o loko o ke kaʻa e hoʻopaneʻe i ka puhi ʻana a hāʻawi i ka manawa pakele hou aku no nā mea holo.
02 Ka Hoʻokaʻawale ʻana o nā ʻUpena Pale Ahi
I nā noi lole ʻoihana, noho nui nā lole kaʻa. Loaʻa i kahi kaʻa ohua maʻamau ma kahi o 20-40 kg o nā mea o loko, ʻo ka hapa nui o ia mau mea he lole, me nā uhi noho, nā uluna, nā kāʻei noho, a me nā poʻo. Pili loa kēia mau mea i ka palekana o nā mea hoʻokele a me nā mea holo, e pono ai nā waiwai pale ahi e hoʻolohi i ka laha ʻana o ka lapalapa a hoʻonui i ka manawa pakele.
Nā olonā pale ahiua wehewehe ʻia he mau olonā ʻaʻole e hoʻā a puhi paha me ka piha ʻole i ka wā e hoʻopā aku ai me kahi kumu ahi, e hana ana i nā lapalapa liʻiliʻi a pio koke ke wehe ʻia ke kumu ahi. Hoʻohana pinepine ʻia ka Limiting Oxygen Index (LOI) e ana i ka lapalapa ʻana, me kahi LOI ma luna o 21% e hōʻike ana i ka lapalapa haʻahaʻa.
Ua māhele ʻia nā olonā pale ahi i ʻelua mau ʻāpana:
- Nā olonā pale ahi maoli
Loaʻa i kēia mau olonā nā hui pale ahi i kūkulu ʻia i loko o kā lākou mau kaulahao polymer, e hoʻoikaika ana i ke kūpaʻa wela, e hoʻonui ana i nā mahana palaho, e kāohi ana i ka hana kinoea lapalapa, a me ka paipai ʻana i ka hoʻokumu ʻana o ke kala. ʻO nā hiʻohiʻona:
- nā olonā aramid (e like me, para-aramid, meta-aramid)
- nā olonā polyimide (e laʻa, Kermel, P84)
- Nā olonā Polyphenylene sulfide (PPS)
- Nā olonā Polybenzimidazole (PBI)
- Nā olonā melamine (e like me Basofil)
Ua hana nui ʻia nā olonā Meta-aramid, polysulfonamide, polyimide, a me PPS ma Kina.
- Nā olonā pale lapalapa i hoʻololi ʻia
Loaʻa i kēia mau olonā ka pale ʻana i ka lapalapa ma o nā mea hoʻohui a i ʻole nā lāʻau lapaʻau ʻili, me:
- Polyester pale ahi
- Nylon pale ahi
- ʻO ka viscose pale ahi
- Polypropylene pale ahi
ʻO nā ʻano hoʻololi e komo pū me ka copolymerization, ka hoʻohuihui ʻana, ka milo ʻana i hui pū ʻia, ka hoʻopili ʻana, a me ka hoʻopau ʻana ma hope.
03 Nā Hoʻohana ʻana o nā ʻUpena Pale Ahi Hana Kiʻekiʻe i ka Palekana Kaʻa
Pono nā mea pale ahi kaʻa e hoʻokō i nā koi kikoʻī ma muli o nā palena o ka wahi. ʻAʻole e like me nā noi ʻē aʻe, pono kēia mau mea e kū i ka hoʻā ʻana a i ʻole e hōʻike i nā helu kuni i kāohi ʻia (e laʻa, ≤70 mm/min no nā kaʻa ohua).
Eia kekahi, ʻo nā manaʻo e pili ana i kēia mau mea:
- Haʻahaʻa ka nui o ka uahi a me ka liʻiliʻi o nā hoʻokuʻu kinoea ʻawahiae hōʻoia i ka palekana o ka poʻe ohua.
- Nā waiwai anti-statice pale aku i nā ahi i hoʻokumu ʻia e ka mahu wahie a i ʻole ka hōʻiliʻili ʻana o ka lepo.
Hōʻike nā helu helu e hoʻohana ana kēlā me kēia kaʻa i 20-42 m² o nā mea lole, e hōʻike ana i ka hiki ke ulu nui i nā lole kaʻa. Ua hoʻokaʻawale ʻia kēia mau lole i nā ʻano hana a me nā mea hoʻonaninani, me ka hoʻoikaika nui ʻana i ka hana—ʻoiai ka pale ʻana i ka lapalapa—ma muli o nā hopohopo palekana.
Hoʻohana ʻia nā lole pale ahi hana kiʻekiʻe i:
- Nā uhi noho
- Nā panela puka
- Nā kaulahao huila
- Nā ʻeke ea
- Nā uhi hale
- Nā mea pale leo a me nā mea hoʻokaʻawale
Hoʻohana nui ʻia nā lole i ulana ʻole ʻia i hana ʻia mai ka polyester, carbon fiber, polypropylene, a me ke aniani fiber i loko o nā loko kaʻa.
ʻO ka hoʻolaha ʻana i nā loko o ke kaʻa e pale aku ai i ke ahi, ʻaʻole wale ia e hoʻonui i ka palekana o nā mea ohua akā he mea kōkua pū kekahi i ka pono o ke kaiāulu.
