(1)Mea Hoʻomoe Haʻahaʻa Haʻahaʻa Uhi Haʻahaʻa ʻAʻole Halogen Polyethylene (XLPE).:
Hoʻokumu ʻia ka mea insulation XLPE ma o ka hoʻohui ʻana i ka polyethylene (PE) a me ka ethylene vinyl acetate (EVA) ma ke ʻano he kumu matrix, me nā mea hoʻohui like ʻole e like me ka halogen-free flame retardants, lubricants, antioxidants, etc., ma o ke kaʻina hana hoʻohui a me ka pelletizing. Ma hope o ka hana ʻana i ka irradiation, hoʻololi ʻo PE mai kahi ʻano molekula laina i kahi ʻano ʻekolu-dimensional, e hoʻololi ana mai kahi mea thermoplastic i kahi plastic thermosetting insoluble.
Loaʻa i nā kaula insulation XLPE nā mea maikaʻi e hoʻohālikelike ʻia me ka PE thermoplastic maʻamau:
1. Hoʻomaikaʻi i ke kūpaʻa ʻana i ka hoʻololi ʻana o ka wela, hoʻomaikaʻi ʻia nā waiwai mechanical i nā wela kiʻekiʻe, a hoʻomaikaʻi i ke kūpaʻa ʻana i ke koʻikoʻi o ke kaiapuni a me ka ʻelemakule wela.
2. Hoʻonui i ka paʻa kemika a me ka pale ʻana i ka solvent, hoʻemi i ke kahe anuanu, a mālama i nā waiwai uila. Hiki i nā mahana hana lōʻihi ke piʻi i 125°C a 150°C. Ma hope o ka hoʻoili ʻana i ka cross-linking, hiki ke hoʻonui ʻia ka mahana pōkole o PE i 250 ° C, e ʻae ana i kahi hiki ke lawe i kēia manawa no nā kaula o ka mānoanoa like.
3. ʻO nā kaula i hoʻopaʻa ʻia ʻo XLPE e hōʻike ana i nā ʻano mechanical maikaʻi loa, wai ʻole, a me ka radiation-resistant, e kūpono ana iā lākou no nā noi like ʻole, e like me ka wili kūloko i nā mea uila, nā alakaʻi kaʻa, nā alakaʻi kukui, nā uea kaʻa haʻahaʻa haʻahaʻa haʻahaʻa, nā uea locomotive. , uwea subway, uwea eli kaiapuni, uwea moku, uwea papa 1E no na mea kanu nukelea, uwea pauma submersible, a me na uwea lawe mana.
ʻO nā kuhikuhi i kēia manawa i ka hoʻomohala ʻana i nā mea hoʻomohala XLPE e pili ana i ka irradiation cross-linked PE power cable insulation material, irradiation cross-linked PE aerial insulation material, a me ka irradiation cross-linked polyolefin sheathing material.
(2)Mea hoʻopololei ʻo Polypropylene (XL-PP) i hoʻopili ʻia:
ʻO ka Polypropylene (PP), ma ke ʻano he plastic maʻamau, he mau hiʻohiʻona e like me ke kaumaha māmā, ka nui o nā kumu waiwai maka, ka maikaʻi o ke kumu kūʻai, ke kūpaʻa maikaʻi ʻana i ka corrosion kemika, ka maʻalahi o ka hana ʻana, a me ka hana hou. Eia nō naʻe, loaʻa iā ia nā palena e like me ka ikaika haʻahaʻa, ke kūpaʻa wela maikaʻi ʻole, ka deformation shrinkage koʻikoʻi, ke kūpaʻa ʻino ʻole, ka brittleness haʻahaʻa haʻahaʻa, a me ke kūpaʻa maikaʻi ʻole i ka wela a me ka ʻelemakule. Ua kaupalena kēia mau palena i kona hoʻohana ʻana i nā polokalamu kelepona. Ke hana nei nā mea noiʻi e hoʻololi i nā mea polypropylene e hoʻomaikaʻi i kā lākou hana holoʻokoʻa, a ua lanakila maikaʻi ka irradiation cross-linked modified polypropylene (XL-PP) i kēia mau palena.
Hiki i nā uwea insulated XL-PP ke hoʻokō i nā hoʻāʻo ahi UL VW-1 a me nā kūlana uea UL-helu 150 ° C. Ma nā noi kelepona pono, hoʻohui pinepine ʻia ʻo EVA me PE, PVC, PP, a me nā mea ʻē aʻe e hoʻoponopono ai i ka hana o ka papa insulation cable.
ʻO kekahi o nā hemahema o ka irradiation cross-linked PP ʻo ia ke komo ʻana i ka hoʻokūkū hoʻokūkū ma waena o ka hoʻokumu ʻana o nā pūʻulu hopena unsaturated ma o nā hopena degradation a me nā hopena hoʻohui ʻia ma waena o nā molekala i hoʻoulu ʻia a me nā molekala nui. Ua hōʻike ʻia nā haʻawina ʻo ka ratio o ka hoʻohaʻahaʻa ʻana i ka hoʻopili ʻana i nā hopena i ka PP irradiation cross-linking ma kahi o 0.8 i ka wā e hoʻohana ai i ka irradiation gamma-ray. No ka hoʻokō ʻana i nā hopena hoʻohui keʻa maikaʻi i ka PP, pono e hoʻohui ʻia nā mea hoʻolaha hoʻohui kea no ka hoʻopili ʻana i ka irradiation. Hoʻohui ʻia, ua kaupalena ʻia ka mānoanoa cross-linking e ka hiki ke komo o nā kaola electron i ka wā irradiation. Ke alakaʻi nei ka iradiation i ka hana ʻana i ke kinoea a me ka huʻihuʻi, ʻoi aku ka maikaʻi no ka hoʻopili ʻana i nā huahana lahilahi akā e kaupalena i ka hoʻohana ʻana i nā kaula paʻa mānoanoa.
(3) Mea Hoʻopololei Ethylene-Vinyl Acetate Copolymer (XL-EVA):
Ke piʻi aʻe nei ke koi no ka palekana o ke kaula, ua ulu wikiwiki ka hoʻomohala ʻana o nā kaula i hoʻopaʻa ʻia me ka halogen-free flame-retardant cross-linked cable. Hoʻohālikelike ʻia me PE, EVA, ka mea e hoʻokomo i nā monomers vinyl acetate i loko o ke kaulahao mole, he haʻahaʻa haʻahaʻa ka crystallinity, ka hopena i ka hoʻomaikaʻi ʻana i ka maʻalahi, ke kūpaʻa hopena, ka hoʻopiha piha ʻana, a me nā waiwai sealing wela. ʻO ka maʻamau, pili nā waiwai o ka resin EVA i ka ʻike o nā monomers vinyl acetate i loko o ke kaulahao mole. ʻO ka maʻiʻo vinyl acetate kiʻekiʻe e alakaʻi i ka hoʻonui ʻana i ka ʻike, hiki ke maʻalahi, a me ka paʻakikī. Loaʻa i ka EVA resin ka hoʻopihapiha hoʻopihapiha maikaʻi a me ka cross-linkability, e hoʻonui nui ʻia ana i nā kaula hoʻopaʻa ʻia i ka halogen-free flame retardant cross-linked.
ʻO ka resin EVA me kahi maʻi vinyl acetate ma kahi o 12% a 24% ka mea maʻamau i hoʻohana ʻia i ka uea a me ka insulation cable. Ma nā noi kelepona maoli, hoʻohui pinepine ʻia ʻo EVA me PE, PVC, PP, a me nā mea ʻē aʻe e hoʻoponopono ai i ka hana o ke kaula insulation layer. Hiki i nā ʻāpana EVA ke hoʻoikaika i ka hoʻopili ʻana, e hoʻomaikaʻi i ka hana kelepona ma hope o ka hoʻopili ʻana.
(4) Mea Hoʻopololei ʻO Ethylene-Propylene-Diene Monomer (XL-EPDM):
ʻO XL-EPDM he terpolymer i haku ʻia me ka ethylene, propylene, a me nā monomers diene non-conjugated, i hoʻopili ʻia ma o ka irradiation. Hoʻohui nā kaula XL-EPDM i nā pono o nā uwea polyolefin-insulated a me nā kaula hoʻopaʻa maʻamau.
1. ʻO ka maʻalahi, ke kūpaʻa, ka hoʻopili ʻole i nā mahana kiʻekiʻe, ka pale ʻana i ka wā kahiko, a me ke kūʻē ʻana i nā piʻi paʻakikī (-60 ° C a 125 ° C).
2. ʻO ke kū'ē o ka ozone, ke kū'ē o UV, ka hana hoʻoheheʻe uila, a me ke kū'ēʻana i ke kino kino.
3. Ke kū'ē i ka aila a me nā mea hoʻoheheʻe e like me ka chloroprene rubber insulation. Hiki ke hana ʻia me ka hoʻohana ʻana i nā lako hana extrusion wela maʻamau, ʻoi aku ka maikaʻi.
XL-EPDM-insulated uwea i ka laulā o nā noi, me ka 'ole i kaupalena 'ia i ka haʻahaʻa-voltage uwea uwea, moku uwea, automotive ignition uwea, mana uwea no ka refrigeration compressors, mining mobile uwea, wili lako, a me nā mea lapaʻau.
ʻO nā hemahema nui o nā kaula XL-EPDM e pili ana i ka pale waimaka maikaʻi ʻole a me nā mea hoʻopili palupalu a me nā waiwai ponoʻī, hiki ke hoʻopilikia i ka hana ma hope.
(5) Silicone Rubber Insulation Material
Loaʻa iā Silicone rubber ka maʻalahi a me ke kūpaʻa maikaʻi loa i ka ozone, ka hoʻokuʻu ʻana o ka corona, a me nā lapalapa, e hana ana ia i mea kūpono no ka hoʻokaʻawale uila. ʻO kāna noi mua i ka ʻoihana uila no nā uea a me nā kaula. Ua kūpono loa nā uwea a me nā kaula silikoni no ka hoʻohana ʻana i nā wahi wela a me nā koi, me ka lōʻihi o ke ola ʻana i hoʻohālikelike ʻia i nā kaula maʻamau. ʻO nā noi maʻamau e pili ana i nā motika wela kiʻekiʻe, nā mea hoʻololi, nā mea hana, nā mea uila a me nā lako uila, nā kaula uila i nā kaʻa kaʻa, a me nā mana moana a me nā kaula hoʻomalu.
I kēia manawa, hoʻopili pinepine ʻia nā kaula silicone rubber-insulated me ka hoʻohana ʻana i ke kaomi lewa me ka ea wela a i ʻole ka mahu kiʻekiʻe. Ke hoʻomau nei nō hoʻi ka noiʻi ʻana i ka hoʻohana ʻana i ka irradiation electron beam no ka lāʻau silicone cross-linking, ʻoiai ʻaʻole ia i lilo i laha i ka ʻoihana kelepona. Me nā holomua hou i ka ʻenehana cross-linking irradiation, hāʻawi ia i kahi kumu kūʻai haʻahaʻa, ʻoi aku ka maikaʻi, a me ke ʻano o ke kaiapuni no nā mea hoʻoheheʻe silicone. Ma o ka electron beam irradiation a i ʻole nā kumu hoʻoheheʻe ʻē aʻe, hiki ke hoʻokō ʻia ka hoʻopili pono ʻana o ka insulation rubber silicone me ka ʻae ʻana i ka mana ma luna o ka hohonu a me ke kiʻekiʻe o ka hoʻopili ʻana e hoʻokō i nā koi noi kikoʻī.
No laila, ʻo ka hoʻohana ʻana i ka ʻenehana cross-linking irradiation no nā mea insulation rubber silicone e paʻa i ka ʻōlelo koʻikoʻi i ka ʻoihana uea a me ke kaula. Manaʻo ʻia kēia ʻenehana e hōʻemi i nā kumukūʻai hana, hoʻomaikaʻi i ka hana hana, a kōkua i ka hōʻemi ʻana i nā hopena ʻino ʻino. Hiki i ka noiʻi a me ka hoʻomohala ʻana i ka wā e hiki mai ana ke hoʻoikaika i ka hoʻohana ʻana i ka ʻenehana cross-linking irradiation no nā mea insulation rubber rubber, e hoʻohana nui ʻia no ka hana ʻana i nā uwea kiʻekiʻe, hana kiʻekiʻe a me nā kaula i ka ʻoihana uila. E hāʻawi kēia i nā hoʻonā pono a paʻa no nā wahi noi.
