I le taimi nei, o mea faʻapipiʻi uaea faʻaaogaina i le gaosiga o le uaea e vaevaeina i ni vaega se tolu: PE, PVC, ma le XLPE.O loʻo faʻaalia mai i lalo le eseesega i le va o mea faʻapipiʻi PE, PVC, ma XLPE faʻaaogaina i uaea.
Ele fa'avasegaina o le fa'avasegaga ma uiga o mea fa'apipi'i uaea
PVC: Polyvinyl chloride, o se polymer e faia e le polymerization saoloto o monomers vinyl chloride i lalo o tulaga patino.O loʻo i ai uiga o le mautu, teteʻe o le acid, teteʻe o le alkali, teteʻe o le corrosion, ma le matua teteʻe, ma e faʻaaogaina lautele i mea faufale, mea e manaʻomia i aso uma, paipa ma paipa, uaea ma uaea, ma mea faʻamaufaʻailoga.E vaevaeina i le vaivai ma le malo: o mea vaivai e masani ona faʻaaogaina e fai ai mea faʻapipiʻi, ata faʻatoʻaga, ma isi, ma faʻaaogaina lautele i le gaosiga o uaea ma uaea faʻapipiʻi faʻapipiʻi, e pei o le polyvinyl chloride faʻapipiʻiina uaea eletise masani;ae o mea malō e masani ona faʻaaogaina e fai ai paipa ma ipu.O le pito sili ona tele o mea polyvinyl chloride o le mumu o le afi, o lea e faʻaaogaina lautele i le fanua o le puipuiga o le afi ma o se tasi lea o mea faʻapipiʻi e masani ona faʻaaogaina mo le afi mumu ma le afi-tetee uaea ma uaea.
PE: O le polyethylene o se resini vevela e faia i le polymerization o le ethylene.E le oona ma le afaina, e sili ona lelei le vevela o le vevela, ma e mafai ona tatalia le tafia o le tele o acids ma alkalis, ma e sili ona lelei le faʻaogaina o le eletise.I le taimi lava e tasi, ona o le polyethylene o loʻo i ai uiga o le leai o se polarity, o loʻo i ai uiga o le maualalo o le gau ma le maualuga o le amio, o lea e masani ona faʻaaogaina e avea o se mea faʻapipiʻi mo uaea maualuga ma uaea.
XLPE: O le polyethylene e feso'ota'i fa'alava'au ose ituaiga sili ona maualuga o mea polyethylene pe a mae'a suiga.A maeʻa le faʻaleleia, o lona tino ma vailaʻau ua faʻaleleia atili pe a faʻatusatusa i mea PE, ma i le taimi lava e tasi, ua faʻaleleia atili le maualuga o le vevela.O le mea lea, o uaea ma uaea e faia i mea faʻapipiʻi polyethylene e fesoʻotaʻi faʻasolosolo e iai mea lelei e le mafai ona faʻatusalia uaea ma uaea polyethylene: mama mama, vevela lelei, faʻamaʻi faʻamaʻi, faʻamaʻi tele faʻamaʻi, ma isi.
Pe a faatusatusa i le thermoplastic polyethylene, XLPE insulation o loʻo i ai tulaga lelei nei:
1 Faʻaleleia le faʻafefe o le vevela, faʻaleleia mea faʻainisinia i le maualuga o le vevela, faʻaleleia atili le faʻafefe o le siosiomaga ma le vevela matua.
2 Faʻaleleia le faʻamautuina o vailaʻau ma le solvent resistance, faʻaitiitia le malulu, faʻatumauina le tulaga muamua o le eletise, o le vevela galue umi e mafai ona oʻo i le 125 ℃ ma le 150 ℃, fesoʻotaʻiga polyethylene insulated uaea ma uaea, faʻaleleia foʻi le mafai gafatia, lona e mafai ona oʻo i le 250 ℃ le vevela o le taimi puʻupuʻu, o le mafiafia tutusa o uaea ma uaea, o le polyethylene o loʻo fesoʻotaʻi i le taimi nei e sili atu le gafatia.
3 XLPE insulated uaea ma uaea e sili ona lelei masini, e le susu ma le faʻavevela mea e tetee ai, o lea e faʻaaogaina lautele.E pei o: uaea feso'ota'iga i totonu o mea fa'aeletise, ta'avale afi, ta'ita'i moli, uaea fa'atonutonu fa'ailo eletise maualalo, uaea locomotive, uaea i lalo ole auala ma uaea, uaea puipuia o le si'osi'omaga, uaea o le gataifale, uaea eletise eletise, uaea eletise maualuga TV. , X-RAY e fanaina uaea maualuga, ma uaea felauaiga eletise ma uaea ma isi alamanuia.
Eseesega i le va o mea faʻapipiʻi uaea PVC, PE, ma XLPE
PVC: maualalo le vevela o le faagaoioia, puupuu le soifua matua vevela, laititi le gafatia o le felauaiga, maualalo le mamafa o le mamafa, ma le tele o le asu ma le kasa oona e lamatia pe a mu.O oloa lautele i totonu o le uaea ma le cable industry, lelei faʻaletino ma mea faʻainisinia, lelei gaioiga faʻatinoga, tau maualalo ma tau faʻatau.Ae o loʻo i ai halogens, ma o le faʻaogaina o le faʻaoga e sili ona tele.
PE: Lelei mea tau eletise, ma mea lelei uma o le PVC o loʻo taʻua i luga.E masani ona faʻaaogaina i le uaea poʻo le uaea insulation, faʻamauina laina faʻamaumauga, maualalo le dielectric faifai pea, talafeagai mo laina faʻamatalaga, laina fesoʻotaʻiga, ma le tele o le faʻaogaina o le uaea pito i luga ole komepiuta.
XLPE: Toeitiiti lava lelei e pei o le PE i mea tau eletise, ae o le umi o le faʻaogaina o le vevela e sili atu le maualuga nai lo le PE, o mea faʻainisinia e sili atu nai lo le PE, ma e sili atu le malosi o le malosi.O se ituaiga fou o oloa fa'alelei fa'alesiosiomaga fa'atasi ai ma le maualuga maualuga o le vevela ma le si'osi'omaga, o se palasitika thermosetting.E masani ona fa'aoga i uaea fa'aeletonika ma nofoaga e mana'omia maualuga le tete'e o le si'osi'omaga.
Eseesega i le va XLPO ma XLPE
XLPO (polyolefin feso'ota'i): EVA, maualalo le asu ma e leai se halogen, fa'avevela fa'asa'o feso'ota'i po'o pa'u pa'u fa'alava fa'alava olefin polymer.O se faaupuga lautele mo se vasega o resini vevela e maua mai i polymerizing poʻo copolymerizing α-olefins e pei ole ethylene, propylene, 1-butene, 1-pentene, 1-hexene, 1-octene, 4-methyl-1-pentene, ma nisi cycloolefins .
XLPE (polyethylene fa'afeso'ota'i): XLPE, polyethylene feso'ota'i, feso'ota'iga silane po'o feso'ota'iga vaila'au, o se resini vevela e faia i le polymerization o le ethylene.I totonu o alamanuia, e aofia ai foi copolymers o le ethylene ma sina vaega itiiti o α-olefins.
