Parizvino, tambo dzekudzivirira tambo dzinoshandiswa mukugadzira tambo dzakakamurwa kuita mapoka matatu: PE, PVC, uye XLPE.Izvi zvinotevera zvinounza mutsauko pakati pezvinhu zvinodzivirira PE, PVC, uye XLPE zvinoshandiswa mumatambo.
Explanation yemhando uye hunhu hwetambo insulating zvinhu
PVC: Polyvinyl chloride, polymer yakaumbwa nemahara polymerization yevinyl chloride monomers pasi pemamiriro chaiwo.Iine hunhu hwekugadzikana, acid resistance, alkali resistance, corrosion resistance, uye kuchembera kuramba, uye inoshandiswa zvakanyanya mukuvaka, zvinodiwa zuva nezuva, mapaipi nemapombi, waya netambo, uye zvekuvharisa zvinhu.Yakakamurwa kuita yakapfava uye yakaoma: dzakapfava dzinonyanya kushandiswa kugadzira zvinhu zvekurongedza, mafirimu ekurima, nezvimwewo, uye anoshandiswa zvakanyanya mukugadzira waya uye tambo yekuvharisa tambo, seyakajairika polyvinyl chloride insulated tambo dzemagetsi;nepo dzakaoma dzichiwanzo shandiswa kugadzira mapaipi nemandiro.Chinhu chikuru chepolyvinyl chloride zvinhu ndeye kudzoreredza moto, saka inoshandiswa zvakanyanya mumunda wekudzivirira moto uye ndeimwe yezvinonyanya kushandiswa zvidziviriro zvetambo zvinodzoreredza uye zvisingadziviriri moto uye tambo.
PE: Polyethylene is thermoplastic resin yakagadzirwa ne polymerization ye ethylene.Haina chepfu uye haina kukuvadza, ine yakanakisa yakadzika tembiricha kuramba, uye inogona kumira nekukukurwa kweakawanda acids uye alkalis, uye ine yakanakisa magetsi ekudzivirira kuita.Panguva imwecheteyo, nokuti polyethylene ine maitiro e-non-polarity, ine maitiro ekurasikirwa kwakaderera uye yakakwirira conductivity, saka inowanzoshandiswa sechinhu chekudzivirira kune high-voltage waya netambo.
XLPE: Muchinjikwa-yakabatana polyethylene imhando yepamusoro ye polyethylene zvinhu mushure mekushandurwa.Mushure mekuvandudzwa, maitiro ayo emuviri uye emakemikari akagadziridzwa zvakanyanya kana achienzaniswa nePE zvinhu, uye panguva imwecheteyo, chiyero chayo chekudzivirira kupisa chakagadziridzwa zvakanyanya.Naizvozvo, waya uye tambo dzakagadzirwa nemuchinjikwa-yakabatana polyethylene insulation zvinhu zvine zvakanakira izvo polyethylene insulation material waya uye tambo hazvigone kuenderana: huremu huremu, kunaka kwekushisa kupisa, kusaita ngura, yakakura kumisa kudzivirira, nezvimwe.
Kuenzaniswa ne thermoplastic polyethylene, XLPE insulation ine zvinotevera zvakanakira:
1 Yakavandudzwa kupisa deformation kuramba, yakagadziridzwa michina zvivakwa pakupisa kwakanyanya, yakagadziridzwa kwezvakatipoteredza kusagadzikana kupwanya kuramba uye kupisa kuchembera kuramba.
2 Kuwedzera kugadzikana kwekemikari uye kusagadzikana kwekunyungudika, kuderera kutonhora kuyerera, kwakachengetedza yekutanga magetsi emagetsi, kwenguva yakareba tembiricha yekushanda inogona kusvika 125 ℃ uye 150 ℃, yakachinjika-yakabatana polyethylene insulated waya uye tambo, zvakare yakagadziridza pfupi-yedunhu kutakura kugona, yayo. yenguva pfupi inotakura tembiricha inogona kusvika 250 ℃, ukobvu hwakafanana hwewaya netambo, mhiri-yakabatana polyethylene ikozvino kutakura kugona kwakakura.
3 XLPE insulated waya uye tambo zvine yakanakisa mechanical, waterproof uye radiation resistance properties, saka dzinoshandiswa zvakanyanya.Zvakadai se: waya dzemukati dzekubatanidza dzemidziyo yemagetsi, mota inotungamira, inotungamira yekuvhenekesa, mota yakaderera-voltage chiratidzo chekudzora waya, waya dzelocomotive, waya dzepasi pevhu netambo, migodhi yekudzivirira nharaunda, tambo dzemugungwa, tambo dzemagetsi enyukireya, waya dzeTV dzakakwirira-voltage. , X-RAY kupfura waya dzemagetsi akakwira, uye waya dzekufambisa magetsi netambo nemamwe maindasitiri.
Misiyano pakati petambo yekuvharisa zvinhu PVC, PE, uye XLPE
PVC: yakaderera tembiricha yekushanda, hupenyu hupfupi hwekuchembera, hudiki hwekutapurirana, huwandu hwakaderera hwekuremerwa, uye hutsi hukuru uye njodzi gasi kana moto.Zvigadzirwa zvakajairwa muindasitiri yewaya uye tambo, yakanaka yemuviri uye yemagetsi zvivakwa, yakanaka yekugadzirisa kuita, mutengo wakaderera uye mutengo wekutengesa.Asi ine halogens, uye sheath kushandiswa ndiyo yakakura.
PE: Yakanakisa magetsi zvivakwa, ine zvese zvakanaka zvePVC zvataurwa pamusoro apa.Inowanzo shandiswa mukugadzira waya kana tambo yekuvharisa, data line insulation, yakaderera dielectric kugara, inokodzera mitsara yedata, mitsara yekutaurirana, uye akasiyana komputa peripheral wire core insulation.
XLPE: Inenge yakanaka sePE mumagetsi emagetsi, nepo tembiricha yenguva refu yekushanda yakakwira zvakanyanya kupfuura PE, iyo mechanical properties iri nani pane PE, uye kuramba kuchembera kuri nani.Rudzi rutsva rwezvakatipoteredza chigadzirwa chine yakanaka yakakwirira tembiricha kuramba uye kudzivirira kwezvakatipoteredza, thermosetting plastiki.Inowanzo shandiswa mumagetsi waya uye nzvimbo dzine yakakwirira yemamiriro ekupikisa zvinodiwa.
Musiyano pakati peXLPO neXLPE
XLPO (cross-linked polyolefin): EVA, utsi hwakaderera uye halogen-isina, mwaranzi muchinjiko-yakabatana kana vulcanized rabha muchinjiko-yakabatana olefin polymer.Izwi rakajairika rekirasi ye thermoplastic resins inowanikwa ne polymerizing kana copolymerizing α-olefins senge ethylene, propylene, 1-butene, 1-pentene, 1-hexene, 1-octene, 4-methyl-1-pentene, uye mamwe cycloolefins. .
XLPE (cross-linked polyethylene): XLPE, cross-linked polyethylene, silane cross-linking kana chemical cross-linking, is thermoplastic resin yakagadzirwa ne polymerization ye ethylene.Muindasitiri, inosanganisirawo copolymers ethylene uye shoma α-olefins.
