Hoʻohana ʻana i nā mea uea haʻahaʻa Halogen-free a me nā mea uea Polyethylene (XLPE) i hoʻopili ʻia.

I nā makahiki i hala iho nei, ua piʻi ka noi no nā mea uila haʻahaʻa halogen-free (LSZH) ma muli o ko lākou palekana a me nā pono o ke kaiapuni. ʻO kekahi o nā mea koʻikoʻi i hoʻohana ʻia i kēia mau kaula he polyethylene crosslinked (XLPE).

1. He ahaPolyethylene i hoʻopaʻa ʻia (XLPE)?

ʻO ka polyethylene i hoʻopili ʻia, i hoʻopau pinepine ʻia ʻo XLPE, he mea polyethylene i hoʻololi ʻia me ka hoʻohui ʻana i kahi crosslinker. Hoʻonui kēia kaʻina hana cross-link i ka wela, mechanical a me nā waiwai kemika o ka mea, e kūpono ia no nā ʻano noi like ʻole. Hoʻohana nui ʻia ʻo XLPE i ke kūkulu ʻana i nā ʻōnaehana pipe service, hydraulic radiant heating a me nā ʻōnaehana hoʻoluʻu, nā paipu wai home a me ka insulation cable kiʻekiʻe.

2. Nā pōmaikaʻi o ka XLPE insulation

Hāʻawi ka insulation XLPE i nā pono ma mua o nā mea kahiko e like me ka polyvinyl chloride (PVC).
Loaʻa kēia mau mea maikaʻi:
ʻO ke kūpaʻa wela: Hiki i ka XLPE ke kū i nā mahana kiʻekiʻe me ka ʻole o ka deformation a no laila kūpono ia no nā noi kiʻekiʻe.
Ke kū'ē kemika: He kū'ē kemika maikaʻi loa ka hoʻolālā crosslinked, e hōʻoiaʻiʻo ana i ka paʻa i nā wahi paʻakikī.
Ka ikaika mīkini: Loaʻa i ka XLPE nā waiwai mechanical maikaʻi loa, me ka pale ʻana i ka ʻaʻahu a me ka haki ʻana.
No laila, hoʻohana pinepine ʻia nā mea uea XLPE i nā pili uila i loko, nā alakaʻi kaʻa, nā alakaʻi kukui, nā uea kiʻekiʻe-voltage i loko o nā kaʻa ikehu hou, nā laina mana hōʻailona haʻahaʻa haʻahaʻa, nā uea locomotive, nā uwea subway, nā kaula hoʻomalu kaiapuni, nā kaula moana, nuklea. nā kaula hoʻomoe mana, nā kaula uila uila kiʻekiʻe, nā uwea uila uila X-RAY a me nā kaula hoʻoili mana.
ʻenehana hoʻopili ʻana i ka polyethylene

Hiki ke hoʻokō ʻia ka hoʻopili ʻana o ka polyethylene ma nā ʻano like ʻole, me ka radiation, peroxide a me ka silane crosslinking. Loaʻa i kēlā me kēia ala kona mau pono a hiki ke koho ʻia e like me nā koi noi kikoʻī. Hoʻopili nui ka degere o ka crosslinking i nā waiwai o ka mea. ʻOi aku ka kiʻekiʻe o ka crosslinking density, ʻoi aku ka maikaʻi o nā waiwai wela a me nā mechanical.

3. He ahahaʻahaʻa-uwahi halogen-noa (LSZH)mea?

Hoʻolālā ʻia nā mea haʻahaʻa haʻahaʻa ʻole halogen (LSZH) i mea e hoʻokuʻu ai nā kaula i ke ahi i ka mea liʻiliʻi loa o ka uahi i ka wā e ʻā ana a ʻaʻole e hoʻopuka i ka uahi ʻawaʻawa halogen. ʻOi aku ka maikaʻi o kēia no ka hoʻohana ʻana i nā Space paʻa a me nā wahi me ka ea maikaʻi ʻole, e like me nā tunnels, nā ʻupena kaʻaahi lalo a me nā hale aupuni. Hana ʻia nā kaula LSZH me nā pūhui thermoplastic a i ʻole thermoset a hana i nā haʻahaʻa haʻahaʻa o ka uahi a me nā uahi ʻawaʻawa, e hōʻoia ana i ka ʻike maikaʻi a me ka hōʻemi ʻana i nā pilikia olakino i ke ahi.

4. LSZH uwea mea noi

Hoʻohana ʻia nā mea kelepona LSZH i nā noi like ʻole kahi mea koʻikoʻi ka palekana a me ka hopohopo.
ʻO kekahi mau polokalamu koʻikoʻi he:
Nā mea kelepona no nā hale aupuni: Hoʻohana mau ʻia nā kaula LSZH i nā hale aupuni e like me nā mokulele, nā kahua kaʻaahi a me nā halemai e hōʻoia i ka palekana i ke ahi.
Kaula no ka lawe ʻana: Hoʻohana ʻia kēia mau kaula i nā kaʻa, nā mokulele, nā kaʻa kaʻaahi a me nā moku e hōʻemi i ka hopena o nā uahi ʻawaʻawa i ka wā o ke ahi.
ʻO ke alahao a me nā uea ʻoihana kaʻaahi lalo: He haʻahaʻa ka uahi a me nā hiʻohiʻona halogen-free nā kaula LSZH, i mea kūpono no ka hoʻohana ʻana i nā ʻoihana kaʻaahi a me lalo.
Nā kaula papa B1: Hoʻohana ʻia nā mea LSZH i nā kaula B1 Class, i hoʻolālā ʻia e hoʻokō i nā kūlana palekana ahi ikaika a hoʻohana ʻia i nā hale kiʻekiʻe a me nā ʻoihana koʻikoʻi ʻē aʻe.

ʻO nā holomua hou i ka XLPE a me ka ʻenehana LSZH e nānā i ka hoʻomaikaʻi ʻana i ka hana o ka mea a me ka hoʻonui ʻana i kāna mau noi. Hoʻokomo ʻia nā mea hou i ka hoʻomohala ʻana i ka polyethylene cross-linked high-density cross-linked polyethylene (XLHDPE), ka mea i hoʻonui i ka pale wela a me ka lōʻihi.

Hoʻohana nui ʻia nā mea ʻenehana polyethylene (XLPE) me ka uahi haʻahaʻa zero-halogen (LSZH) i nā ʻoihana like ʻole ma muli o ko lākou ʻano wela maikaʻi loa, kemika a me ka mīkini. Ke hoʻomau nei kā lākou mau noi me ka holomua mau o ka ʻenehana a me ka piʻi nui ʻana o ka noi no nā mea palekana a ʻoi aku ka maikaʻi o ke kaiapuni.

Ke hoʻomau nei ka hoʻonui ʻana o ka noi no nā mea kelepona hilinaʻi a palekana, manaʻo ʻia ʻo XLPE a me LSZH e hana nui i ka hoʻokō ʻana i kēia mau koi.
