Chii chinonzi Non-Halogen Insulation Materials?

(1)Muchinjikwa-Yakabatana Yakaderera Utsi Zero Halogen Polyethylene (XLPE) Insulation Material:
XLPE insulation material inogadzirwa nekubatanidza polyethylene (PE) uye ethylene vinyl acetate (EVA) seye base matrix, pamwe chete nemhando dzakasiyana-siyana dzakadai sehalogen-isina flame retardants, lubricant, antioxidants, nezvimwewo, kuburikidza nekugadzirisa uye pelletizing maitiro. Mushure mekugadzirisa irradiation, PE inoshandura kubva kune mutsara mamorekuru chimiro kuita matatu-dimensional chimiro, ichichinja kubva kune thermoplastic zvinhu kuenda kune isinganyunguke thermosetting purasitiki.

XLPE insulation tambo dzine akati wandei mabhenefiti kana ichienzaniswa neyakajairika thermoplastic PE:
1. Kuvandudzwa kwekupikisa kwekupisa kwekupisa, kuwedzeredza ma mechanical properties pakupisa kwepamusoro, uye nekuvandudza kupikisa kunokonzera kushungurudzika kwezvakatipoteredza uye kukwegura kwekushisa.
2. Kuwedzerwa kugadzikana kwemakemikari uye kusagadzikana kwekugadzirisa, kuderedza kutonhora kuyerera, uye kuchengetedza magetsi emagetsi. Tembiricha yekushanda kwenguva refu inogona kusvika 125°C kusvika 150°C. Mushure mekuyambuka-kubatanidza kugadzirisa, iyo pfupi-yedunhu tembiricha yePE inogona kuwedzerwa kusvika 250 ° C, ichibvumira kune yakanyanya kukwirira ikozvino-yekutakura tambo dzehukobvu hwakafanana.
3. XLPE-insulated tambo dzinoratidzawo zvakanakisa mechanical, waterproof, uye radiation-resistant properties, zvichiita kuti dzive dzakakodzera kushandiswa kwakasiyana siyana, senge wiring yemukati mumidziyo yemagetsi, motor lead, lighting lead, mota dzakaderera-voltage signal control waya, locomotive wires. , tambo dzezvitima zvepasi pevhu, tambo dzemigodhi dzinochengetedza zvakatipoteredza, tambo dzengarava, tambo dzeE-giredhi dzezvigadzirwa zvemagetsi enyukireya, tambo dzepombi dzinonyura mumvura, uye tambo dzekufambisa magetsi.

Mafambiro azvino muXLPE insulation zvinhu kuvandudzwa anosanganisira irradiation-yakabatana PE simba tambo yekumisa zvinhu, irradiation-yakabatana-yakabatana PE aerial insulation zvinhu, uye irradiation-yakabatana murazvo-inodzoreredza polyolefin sheathing zvinhu.

(2)Muchinjikwa-Yakabatanidzwa Polypropylene (XL-PP) Insulation Material:
Polypropylene (PP), sepurasitiki yakajairwa, ine hunhu hwakadai sehuremu huremu, akawanda mbishi zvinyorwa, mutengo-unoshanda, yakanakisa kemikari inodzivirirwa nekuora, kureruka kwekuumbwa, uye kushandiswazve. Nekudaro, ine painogumira senge kuderera kwesimba, kushomeka kwekudzivirira kupisa, kuderera kukuru kwekushomeka, kushomeka kwekusagadzikana, kuderera-kupisa brittleness, uye kushomeka kwekudzivirira kupisa uye kuchembera kweokisijeni. Izvi zvinogumira zvakaganhurira kushandiswa kwayo mumashandisirwo etambo. Vatsvagiri vanga vachishanda kushandura polypropylene zvinhu kuti vavandudze kuita kwavo kwese, uye irradiation cross-linked modified polypropylene (XL-PP) yakakunda zvinogumira izvi.

XL-PP insulated waya dzinogona kusangana neUL VW-1 flame bvunzo uye UL-yakatemerwa 150 ° C waya zviyero. Mukushandisa tambo dzekushandisa, EVA inowanzo sanganiswa nePE, PVC, PP, uye zvimwe zvinhu kugadzirisa mashandiro etambo yekuvharisa tambo.

Imwe yezvakaipira irradiation cross-linked PP ndeyekuti inosanganisira kuita kwemakwikwi pakati pekuumbwa kweasina unsaturated magumo mapoka kuburikidza nekushatisa maitiro uye kuyambuka-kubatanidza maitiro pakati pemamorekuru anomutswa uye mamorekuru emahara radicals. Zvidzidzo zvakaratidza kuti reshiyo yekudzikira kusvika kuyambuka-inobatanidza maitiro muPP irradiation cross-linking ingangoita 0.8 kana uchishandisa gamma-ray irradiation. Kuti uwane zvinobudirira muchinjika-yekubatanidza maitiro muPP, muchinjika-inobatanidza vanokurudzira vanofanirwa kuwedzerwa kune irradiation cross-linking. Pamusoro pezvo, iyo inoshanda muchinjika-inobatanidza ukobvu inoganhurwa nekugona kupinda kwemagetsi emagetsi panguva yekuvhenekesa. Irradiation inotungamira mukugadzirwa kwegasi uye kupupa, izvo zvinobatsira pakuyambuka-kubatanidza kwezvigadzirwa zvitete asi zvinomisa kushandiswa kwetambo dzakakora-madziro.

(3) Cross-Linked Ethylene-Vinyl Acetate Copolymer (XL-EVA) Insulation Material:
Sezvo kudiwa kwekuchengetedzwa kwetambo kunowedzera, kuvandudzwa kwehalogen-isina murazvo-retardant cross-linked cables yakakura nekukurumidza. Kuenzaniswa nePE, EVA, iyo inosuma vinyl acetate monomers mucheni yemolecular, ine yakaderera crystallinity, zvichikonzera kugadziridzwa kuchinjika, kukanganisa kupikisa, kuenderana kwekuzadza, uye kupisa chisimbiso. Kazhinji, zvivakwa zveEVA resin zvinoenderana nezviri mukati mevinyl acetate monomers mune molecular chain. Yakakwira vinyl acetate yemukati inotungamira kuwedzera pachena, kuchinjika, uye kuoma. EVA resin ine yakanakisa mafirita anoenderana uye muchinjika-kubatana, zvichiita kuti iwedzere kufarirwa muhalogen-isina murazvo-inodzoreredza muchinjika-yakabatana tambo.

EVA resin ine vinyl acetate yemukati inosvika 12% kusvika 24% inowanzoshandiswa mukuisa waya uye tambo. Mumashandisirwo chaiwo etambo, EVA inowanzo sanganiswa nePE, PVC, PP, uye zvimwe zvinhu kugadzirisa mashandiro etambo yekuvharisa tambo. EVA zvikamu zvinogona kusimudzira kuyambuka-kubatanidza, kuvandudza tambo mashandiro mushure mekuyambuka-kubatanidza.

(4) Cross-Linked Ethylene-Propylene-Diene Monomer (XL-EPDM) Insulation Material:
XL-EPDM inonzi terpolymer inoumbwa ne ethylene, propylene, uye isina-conjugated diene monomers, yakabatanidzwa kuburikidza neirradiation. XL-EPDM tambo dzinobatanidza zvakanakira polyolefin-insulated tambo uye akajairika rabha-insulated tambo:
1. Kuchinja, kusimba, kusanamatira pakupisa kwepamusoro, kuramba kukwegura kwenguva refu, uye kurwisana nemamiriro okunze akaoma (-60 ° C kusvika 125 ° C).
2. Ozone kuramba, UV kuramba, magetsi ekudzivirira kushanda, uye kuramba kune kemikari corrosion.
3. Kupokana nemafuta uye zvinonyungudutsa zvinofananidzwa ne general-chinangwa chloroprene rubber insulation. Inogona kugadzirwa uchishandisa yakajairwa inopisa extrusion yekugadzirisa michina, ichiita kuti ishande-inoshanda.

XL-EPDM-insulated cables ine zvakawanda zvekushandisa, kusanganisira asi kwete kugumira kune yakaderera-voltage tambo dzemagetsi, tambo dzengarava, tambo dzemoto dzinopisa, tambo dzekudzora dzefiriji compressors, migodhi mbozha tambo, midziyo yekuchera, uye michina yekurapa.

Izvo zvakanyanya kuipa kwetambo dzeXL-EPDM zvinosanganisira kushomeka kwemisodzi uye kusagadzikana kunamatira uye kuzvinamira zvinhu, izvo zvinogona kukanganisa kunotevera kugadzirisa.

(5) Silicone Rubber Insulation Material

Silicone rabha ine inochinjika uye yakanakisa kuramba ozone, corona discharge, uye marimi, zvichiita kuti ive chinhu chakanakira kuvharisa magetsi. Chishandiso chayo chikuru muindasitiri yemagetsi ndeye waya netambo. Silicone rabha waya uye tambo dzakanyanya kukodzera kushandiswa munzvimbo dzepamusoro-tembiricha uye dzinoda nharaunda, dzine hupenyu hwakareba zvakanyanya kana zvichienzaniswa netambo dzakajairwa. Zvishandiso zvakajairika zvinosanganisira mota dzemhando yepamusoro-tembiricha, ma transformer, majenareta, zvemagetsi nemagetsi, tambo dzekubatidza mumotokari dzekutakura, uye simba remugungwa netambo dzekudzora.

Parizvino, silicone rabha-insulated tambo dzinowanzo kuchinjika-yakabatana uchishandisa kungave kwemuchadenga kudzvanywa nemhepo inopisa kana yakakwirira-kudzvanywa chiutsi. Kune zvakare tsvakiridzo irikuenderera mberi yekushandisa electron beam irradiation ye cross-linking silicone rabha, kunyangwe isati yave kuwanda muindasitiri yematambo. Nekufambira mberi kwazvino mu irradiation cross-linking tekinoroji, inopa yakaderera-mutengo, inoshanda zvakanyanya, uye ine hushamwari imwe nzira yesilicone rubber insulation zvinhu. Kuburikidza neelectron beam irradiation kana mamwe masosi emwaranzi, kuchinjika-kuchinjika kwesilicone rubber insulation kunogona kuwanikwa uku uchibvumira kutonga pamusoro pekudzika uye dhigirii rekuyambuka-kusangana kusangana nezvinodiwa zvekushandisa.

Nekudaro, kushandiswa kweirradiation cross-linking tekinoroji yesilicone rubber insulation zvinhu zvine vimbiso yakakosha muindasitiri yewaya netambo. Iyi tekinoroji inotarisirwa kudzikisira mitengo yekugadzira, kuvandudza hunyanzvi hwekugadzira, uye kubatsira mukudzikisa kuipa kwakashata kwezvakatipoteredza. Kutsvagisa kweramangwana uye kuedza kwekusimudzira kunogona kufambisa kushandiswa kweirradiation cross-linking tekinoroji yesilicone rubber insulation zvinhu, zvichiita kuti zvishande zvakanyanya pakugadzira tembiricha, waya dzepamusoro-soro uye tambo muindasitiri yemagetsi. Izvi zvichapa mamwe akavimbika uye akasimba mhinduro kune dzakasiyana nzvimbo dzekushandisa.
