ʻO nā mea hoʻopili kelepona: PVC, PE, a me XLPE - He hoʻohālikelike kikoʻī

Hoʻolauna

I ka hana ʻana i nā kaula uila, ʻo ke koho ʻana i ka mea insulation kūpono he mea koʻikoʻi. ʻAʻole pale wale ka papa insulation i ke kaula mai ka pōʻino o waho akā e hōʻoiaʻiʻo i ka hana uila palekana a maikaʻi. Ma waena o nā mea i loaʻa, PVC, PE, a me XLPE ka mea maʻamau i hoʻohana ʻia. Akā, he aha ka mea e ʻokoʻa ai lākou, a pehea ʻoe e hoʻoholo ai i ka mea i kūpono no kāu mau pono? E luʻu kākou i nā kikoʻī ma ke ʻano maʻalahi a maʻalahi ke hoʻomaopopo.

ʻO ka nānā ʻana o kēlā me kēia mea hoʻohuihui

PVC (Polyvinyl Chloride)

ʻO PVC kahi ʻano plastik i hana ʻia mai ka polymerized vinyl chloride. He mea maʻalahi a hoʻohana nui ʻia i nā ʻoihana like ʻole. No nā kaula, kū ka PVC no ka mea paʻa, paʻa, a kū i ka waika, alkali, a me ka ʻelemakule.

• PVC palupalu: Hiki ke maʻalahi a hoʻohana mau ʻia no ka hana ʻana i nā mea hoʻopihapiha, nā kiʻiʻoniʻoni, a me nā papa insulation i nā kaula haʻahaʻa haʻahaʻa. Loaʻa i nā laʻana nā kaula mana maʻamau.
• PVC paakiki: ʻoi aku ka paʻakikī a hoʻohana ʻia no ka hana ʻana i nā paipu a me nā panela.

ʻO kekahi o nā hiʻohiʻona maikaʻi o PVC ʻo kona kūpaʻa ʻana i ka lapalapa ahi, kahi e kaulana ai ia no nā kaula pale ahi. Eia nō naʻe, loaʻa iā ia kahi ʻaoʻao: ke puhi ʻia, hoʻokuʻu ia i ka uahi ʻawaʻawa a me nā kinoea ʻino.

PE (Polyethylene)

ʻO ka PE he mea ʻawaʻawa ʻole, māmā māmā i hana ʻia e ka polymerizing ethylene. Kaulana ʻo ia no kāna mau waiwai hoʻokaʻawale uila maikaʻi loa a me ke kūʻē ʻana i nā kemika a me ka makū. ʻOi aku ka maikaʻi o ka PE i ka lawelawe ʻana i nā mahana haʻahaʻa a he mau dielectric haʻahaʻa, e hōʻemi ana i ka nalowale o ka ikehu.

Ma muli o kēia mau hiʻohiʻona, hoʻohana pinepine ʻia ʻo PE no ka hoʻokaʻawale ʻana i nā uwea mana kiʻekiʻe-voltage, nā kelepona ʻikepili, a me nā uea kamaʻilio. He kūpono ia no nā noi kahi mea nui ka hana uila, akā ʻaʻole ia e like me ka pale ahi e like me PVC.

XLPE (Polyethylene i hoʻopili ʻia)

ʻO XLPE kahi mana hou o PE. Hana ʻia ia e nā molekele polyethylene i hoʻohui ʻia i ke kino a i ʻole ke kino, kahi e hoʻomaikaʻi nui ai i kāna mau waiwai.

Hoʻohālikelike ʻia me ka PE maʻamau, hāʻawi ʻo XLPE i ka pale wela ʻoi aku ka maikaʻi, ka ikaika mechanical kiʻekiʻe, a me ka lōʻihi o ka lōʻihi. ʻAʻole kūʻē ia i ka wai a me ka radiation, kūpono ia no ke koi ʻana i nā noi e like me nā uwea lalo, nā mea kanu nuklea, a me nā kaiapuni kai.

Nā ʻokoʻa nui ma waena o PVC, PE, a me XLPE

1. Hana wela

• PVC: He kūpono no nā kaiapuni haʻahaʻa haʻahaʻa akā he palena palena ʻole ka wela. ʻAʻole kūpono ia no nā noi e koi ana i ka pale wela kiʻekiʻe.
• PE: Mālama maikaʻi i nā wela haʻahaʻa akā hoʻomaka e hoʻohaʻahaʻa ma lalo o ka wela nui.
• XLPE: Excels ma nā wahi wela wela. Hiki iā ia ke hana mau ma 125 ° C a kū i nā mahana pōkole a hiki i 250 ° C, e hoʻomaʻamaʻa maikaʻi ia no nā noi kiʻekiʻe.

2. Pono Uila

• PVC: Nā waiwai uila maikaʻi no ka hoʻohana maʻamau.
• PE: Hoʻopili uila maikaʻi loa me ka nalowale o ka ikehu haʻahaʻa, kūpono no nā noi kiʻekiʻe a i ʻole nā ​​​​voltage kiʻekiʻe.
• XLPE: Mālama i nā waiwai uila maikaʻi loa o PE me ka hāʻawi ʻana i ka hana ʻoi aku ka maikaʻi ma lalo o nā wela kiʻekiʻe.

3. Ka lōʻihi a me ka ʻelemakule

• PVC: Hiki ke ʻelemakule i ka wā lōʻihi, ʻoi aku ka nui ma nā wahi wela.
• PE: ʻOi aku ka maikaʻi o ke kūʻē ʻana i ka ʻelemakule akā ʻaʻole naʻe e like me XLPE.
• XLPE: Kūʻē kūʻokoʻa i ka ʻelemakule, ke koʻikoʻi o ke kaiapuni, a me ka lole mechanical, e lilo ia i koho mau loa.

4. Palekana ahi

• PVC: Paʻa ke ahi akā hoʻokuʻu i ka uahi ʻawaʻawa a me nā kinoea ke puhi ʻia.
• PE: ʻAʻohe mea ʻawaʻawa akā hiki ke puhi ʻia, no laila ʻaʻole ia ka koho maikaʻi loa no nā wahi paʻa ahi.
• XLPE: Loaʻa i nā ʻano ʻokoʻa haʻahaʻa haʻahaʻa, halogen-free, e ʻoi aku ka palekana i nā kūlana ahi.

5. Kumukuai

• PVC: ʻO ke koho kūpono loa, hoʻohana nui ʻia no nā uwea maʻamau.
• PE: ʻOi aku ke kumukūʻai ma muli o kāna mau waiwai uila.
• XLPE: ʻO ke kumu kūʻai nui loa akā kūpono ke kumu kūʻai no nā noi hana kiʻekiʻe a koʻikoʻi paha.

Nā noi o PVC, PE, a me XLPE i nā Uila

Nā noi PVC

• Nā kaula uila haʻahaʻa haʻahaʻa
• Uea hana nui
• ʻO nā kaula pale ahi i hoʻohana ʻia i nā hale a me nā hoʻonohonoho ʻoihana

Noi PE

• Nā uwea mana mana kiʻekiʻe
• Nā kaula ʻikepili no nā lolouila a me nā pūnaewele kamaʻilio
• Uea hōʻailona a hoʻomalu

Nā noi XLPE

• ʻO nā uwea hoʻoili mana, me nā uwea lalo a me ka moana
• ʻO nā kaiapuni wela kiʻekiʻe e like me nā mea kanu nuklea
• Nā hoʻonohonoho ʻenehana kahi mea koʻikoʻi ka lōʻihi a me ka palekana

Hoʻohālikelike o XLPO a me XLPE

XLPO (Polyolefin pili pili)

• Hana ʻia mai nā olefins like ʻole, me ka EVA a me nā pūhui halogen-free.
• Ua ʻike ʻia no kāna mau waiwai haʻahaʻa uahi a me ka halogen-ʻole, e hoʻomaikaʻi i ke kaiapuni.

XLPE (Polyethylene i hoʻopili ʻia)

• Hoʻopili i ka polyethylene cross-linking e hoʻomaikaʻi i ka lōʻihi a me ka pale wela.
• He kūpono no nā noi kiʻekiʻe-koʻikoʻi, wela wela.

ʻOiai ua hoʻopili ʻia nā mea ʻelua, ʻoi aku ka maikaʻi o XLPO no nā noi eco-friendly a me ka uahi haʻahaʻa, ʻoiai ʻo XLPE e ʻālohilohi ana i nā ʻenehana a me nā hana kiʻekiʻe.

Ka hopena

ʻO ke koho ʻana i ka mea hoʻokaʻawale kelepona pono e pili ana i kāu mau pono kikoʻī. ʻO PVC kahi koho kūpono no ka hoʻohana maʻamau, hāʻawi ʻo PE i ka hana uila ʻoi aku ka maikaʻi, a hāʻawi ʻo XLPE i ka lōʻihi like ʻole a me ka pale wela no nā noi koi. Ma ka hoʻomaopopo ʻana i ka ʻokoʻa ma waena o kēia mau mea, hiki iā ʻoe ke hoʻoholo i ka ʻike e hōʻoia i ka palekana, ka hana, a me ka lōʻihi o kou mau ʻōnaehana kelepona.

ʻO Danyang Winpower Wire a me Cable Mfg Co., Ltd.ʻO ka mea hana i nā lako uila a me nā lako, nā huahana nui e pili ana i nā kaula uila, nā wili uila a me nā mea hoʻohui uila. Hoʻohana ʻia i nā ʻōnaehana home akamai, nā ʻōnaehana photovoltaic, nā ʻōnaehana mālama ikehu, a me nā ʻōnaehana kaʻa uila
