Ka Hoʻohana ʻana o nā Mea Uea Halogen-free Haʻahaʻa a me nā Mea Uea Polyethylene Cross-linked (XLPE)

I nā makahiki i hala iho nei, ua piʻi nui ke koi no nā mea uwea halogen-free haʻahaʻa-uahi (LSZH) ma muli o ko lākou palekana a me nā pono o ke kaiapuni. ʻO kekahi o nā mea nui i hoʻohana ʻia i loko o kēia mau uwea, ʻo ia ka polyethylene crosslinked (XLPE).

1. He aha ka meaʻO ka Polyethylene i hoʻopili ʻia (XLPE)?

ʻO ka polyethylene cross-linked, i hoʻopōkole pinepine ʻia ʻo XLPE, he mea polyethylene i hoʻololi ʻia me ka hoʻohui ʻana o kahi crosslinker. Hoʻonui kēia kaʻina hana cross-linking i nā waiwai thermal, mechanical a me kemika o ka mea, e kūpono ai no nā ʻano hana like ʻole. Hoʻohana nui ʻia ʻo XLPE i nā ʻōnaehana paipu lawelawe kūkulu hale, nā ʻōnaehana hoʻomehana a me ka hoʻoluʻu ʻana o ka radiant hydraulic, nā paipu wai home a me ka insulation uwea voltage kiʻekiʻe.

2. Nā pono o ka hoʻokaʻawale ʻana o XLPE

Hāʻawi ka insulation XLPE i kekahi mau pono ma luna o nā mea kuʻuna e like me ka polyvinyl chloride (PVC).
ʻO kēia mau pono:
Paʻa wela: Hiki i ka XLPE ke kū i nā mahana kiʻekiʻe me ka ʻole o ka deformation a no laila kūpono no nā noi kiʻekiʻe.
Ke kūpaʻa kemika: He kūpaʻa kemika maikaʻi loa ka ʻano i hoʻopili ʻia, e hōʻoiaʻiʻo ana i ka lōʻihi i nā ʻano ʻino.
Ikaika mīkini: Loaʻa iā XLPE nā waiwai mechanical maikaʻi loa, me ke kūpaʻa ʻana i ka ʻaʻahu a me ka haki ʻana o ke kaumaha.
No laila, hoʻohana pinepine ʻia nā mea kaula XLPE i nā pilina uila kūloko, nā alakaʻi motika, nā alakaʻi kukui, nā uea uila kiʻekiʻe i loko o nā kaʻa ikehu hou, nā laina hoʻomalu hōʻailona haʻahaʻa haʻahaʻa, nā uea locomotive, nā uea subway, nā uea pale kaiapuni mining, nā uea moana, nā uea hoʻomoe mana nuklea, nā uea uila TV kiʻekiʻe, nā uea uila kiʻekiʻe X-RAY a me nā uea hoʻoili mana.
ʻenehana hoʻopili ʻana o ka polyethylene

Hiki ke hoʻokō ʻia ke crosslinking o ka polyethylene ma o nā ʻano hana like ʻole, me ka radiation, peroxide a me ka silane crosslinking. Loaʻa i kēlā me kēia ʻano hana kona mau pono a hiki ke koho ʻia e like me nā koi noi kikoʻī. Hoʻopilikia nui ke kekelē o ka crosslinking i nā waiwai o ka mea. ʻO ke kiʻekiʻe o ka crosslinking density, ʻoi aku ka maikaʻi o nā waiwai thermal a me mechanical.

3. He aha nā meaʻaʻohe halogen uahi haʻahaʻa (LSZH)nā mea hana?

Ua hoʻolālā ʻia nā mea halogen-free haʻahaʻa-uahi (LSZH) i mea e hoʻokuʻu ai nā kaula i hōʻike ʻia i ke ahi i ka liʻiliʻi loa o ka uahi i ka wā e ʻā ana a ʻaʻole hoʻi e hana i ka uahi halogen ʻawahia. ʻOi aku ka kūpono o kēia no ka hoʻohana ʻana ma nā wahi paʻa a me nā wahi me ka ea maikaʻi ʻole, e like me nā tunnels, nā pūnaewele kaʻaahi ma lalo o ka honua a me nā hale lehulehu. Hana ʻia nā kaula LSZH me nā hui thermoplastic a thermoset paha a hana i nā pae haʻahaʻa loa o ka uahi a me nā uahi ʻawahia, e hōʻoiaʻiʻo ana i ka ʻike maikaʻi a me ka hoʻemi ʻana i nā pilikia olakino i ka wā o ke ahi.

4. Hoʻohana ʻana i nā mea kaula LSZH

Hoʻohana ʻia nā mea uwea LSZH i nā ʻano hana like ʻole kahi e koʻikoʻi ai nā hopohopo no ka palekana a me ke kaiapuni.
ʻO kekahi mau noi koʻikoʻi:
Nā mea uwea no nā hale aupuni: Hoʻohana pinepine ʻia nā uwea LSZH i nā hale aupuni e like me nā kahua mokulele, nā kahua kaʻaahi a me nā haukapila e hōʻoia i ka palekana i ka wā o ke ahi.
Nā kaula no ka halihali: Hoʻohana ʻia kēia mau kaula i nā kaʻa, nā mokulele, nā kaʻa kaʻaahi a me nā moku e hōʻemi i ka pilikia o nā uahi ʻawahia i ka wā e loaʻa ai ke ahi.
ʻO nā kaula pūnaewele alahao tunnel a me lalo o ka honua: He haʻahaʻa ka uahi a me nā ʻano halogen-free nā kaula LSZH, e kūpono ai lākou no ka hoʻohana ʻana i nā pūnaewele alahao tunnel a me lalo o ka honua.
Nā kaula Papa B1: Hoʻohana ʻia nā mea LSZH i nā kaula Papa B1, i hoʻolālā ʻia e hoʻokō i nā kūlana palekana ahi paʻa a hoʻohana ʻia i nā hale kiʻekiʻe a me nā ʻoihana koʻikoʻi ʻē aʻe.

ʻO nā holomua hou i ka ʻenehana XLPE a me LSZH e kālele ana i ka hoʻomaikaʻi ʻana i ka hana o ka mea a me ka hoʻonui ʻana i kāna mau noi. ʻO nā hana hou e pili ana i ka hoʻomohala ʻana o ka polyethylene cross-linked high-density (XLHDPE), ka mea i hoʻonui i ke kūpaʻa wela a me ka lōʻihi.

Hoʻohana nui ʻia nā mea polyethylene cross-linked (XLPE) a me nā mea kaula haʻahaʻa-uahi ʻole (LSZH) i nā ʻoihana like ʻole ma muli o ko lākou mau waiwai wela, kemika a me ka mechanical maikaʻi loa. Ke hoʻomau nei kā lākou noi i ka ulu ʻana me ka holomua mau o ka ʻenehana a me ka hoʻonui ʻana o ke koi no nā mea palekana a ʻoi aku ka launa pū me ke kaiapuni.

Ke hoʻomau nei ka piʻi ʻana o ke koi no nā mea uwea hilinaʻi a palekana hoʻi, manaʻo ʻia ʻo XLPE lāua ʻo LSZH e hoʻokani i kahi kuleana koʻikoʻi i ka hoʻokō ʻana i kēia mau koi.
