ʻO ka ʻaʻahu kaula ka papa waho loa o ke kaula.ʻO ia ka mea pale nui loa i ke kaula e pale i ka palekana o ka hale i loko a pale i ke kaula mai ka pōʻino mechanical i ka wā a ma hope o ke kau ʻana.ʻAʻole i manaʻo ʻia nā ʻaʻahu kelepona e hoʻololi i ka pale kaua i hoʻoikaika ʻia i loko o ke kaula, akā hiki iā lākou ke hāʻawi i kahi kiʻekiʻe kiʻekiʻe, ʻoiai he palena ʻole, ke ʻano o ka pale.Hoʻohui ʻia, hāʻawi nā kāʻei kelepona i ka pale mai ka makū, nā kemika, nā kukui UV, a me ka ozone.No laila, he aha nā mea i hoʻohana ʻia no ka sheathing cable?
1. Uila sheath material: PVC
ʻO nā mea kelepona nā ʻāpana i hoʻomākaukau ʻia e ka hui ʻana, kneading a extruding polyvinyl chloride e like me ka resin base, hoʻohui i nā stabilizers, plasticizers, inorganic fillers e like me ka calcium carbonate, auxiliaries a me nā lubricants.
Hiki ke hoʻolālā ʻia ka PVC no ka hoʻohana ʻana i nā ʻano like ʻole a me nā noi.He mea maʻalahi ke hoʻohana, hiki ke maʻalahi, ikaika kūpono, a he mau mea pale ahi/ʻaila.
Eia nō naʻe, loaʻa i kēia mea nā mea ʻino i ke kaiapuni a me ke kino o ke kanaka, a he nui nā pilikia ke hoʻohana ʻia i nā wahi kūikawā.Me ka hoʻonui ʻana i ka ʻike kaiapuni o ka poʻe a me ka hoʻomaikaʻi ʻana i nā pono hana waiwai, ua kau ʻia nā koi kiʻekiʻe no nā mea PVC.
2. Uila sheath material: PE
Ma muli o ka maikaʻi o ka hoʻoheheʻe ʻana i ka uila a me nā ʻano hana hoʻoponopono maikaʻi, hoʻohana nui ʻia ka polyethylene ma ke ʻano he mea uhi no nā uea a me nā kaula, a hoʻohana nui ʻia i ka papa insulation a me ka sheath layer o nā uea a me nā kaula.
ʻO nā waiwai uila maikaʻi a me ke kūpaʻa insulation kiʻekiʻe loa.Hiki ke pa'akikī a 'o'ole'a loa ka polyethylene, akā 'oi aku ka ma'alahi o ka PE ha'aha'a ha'aha'a (LDPE).ʻO ka PE i hoʻonohonoho pono ʻia he kūpaʻa maikaʻi loa.
ʻO ka laina molecular structure o ka polyethylene e maʻalahi ke hoʻololi i nā wela kiʻekiʻe.No laila, i nā noi PE ma ka uea a me ka ʻoihana kelepona, hoʻopili pinepine ʻia ka polyethylene i loko o kahi hoʻolālā pūnaewele, me ka pale ʻana i nā wela kiʻekiʻe.Kū'ē i ka deformation.
Hoʻohana ʻia ka polyethylene cross-linked (XLPE) a me ka polyvinyl chloride (PVC) ma ke ʻano he mea hoʻolalelale no nā uea a me nā kaula, akā ʻoi aku ka maikaʻi o nā uea XLPE a me nā kelepona ma mua o nā uea PVC a ʻoi aku ka maikaʻi o ka hana.
3. Cable sheath mea: PUR
ʻO ke kaula PUR kekahi ʻano o ke kaula.ʻO ka mea o ka PUR cable ka mea maikaʻi o ka pale ʻana i ka aila a me ke kūpaʻa ʻana, ʻoiai ʻo PVC i hana ʻia i nā mea maʻamau.I ka ʻoihana kelepona i nā makahiki i hala iho nei, ua lilo ka polyurethane i mea nui.I kekahi mahana, ua like ka waiwai mechanical o ka mea me ka rubber.ʻO ka hui pū ʻana o ka thermoplasticity a me ka elasticity ka hopena i ka TPE thermoplastic elastomer.
Hoʻohana nui ʻia ia i nā mīkini ʻenehana a me nā mea hana, nā ʻōnaehana mana hoʻouna, nā ʻenehana ʻenehana like ʻole, nā mea hana hoʻāʻo, nā lako uila, nā mea pono hale, electromechanical, kīhini a me nā mea hana ʻē aʻe, a hoʻohana ʻia no ka hoʻolako mana a me nā pilina hōʻailona ma nā wahi paʻakikī. a me nā manawa ʻē aʻe.
4. Mea hoʻopaʻa kaula: TPE/TPR
Hāʻawi nā elastomers Thermoplastic i nā waiwai haʻahaʻa haʻahaʻa maikaʻi loa me ka ʻole o ka lilo o nā thermosets.Loaʻa iā ia ke kūpaʻa kemika a me ka ʻaila a maʻalahi loa.ʻO ke kūpaʻa ʻaʻahu maikaʻi a me ke ʻano o ka ʻili, akā ʻaʻole lōʻihi e like me ka PUR.
5. Uila sheath mea: TPU
ʻO ke kaula polyurethane e pili ana i ke kaula e hoʻohana ana i nā mea polyurethane ma ke ʻano he insulation a i ʻole sheath.ʻO kona kūpale ʻaʻahu ʻoi loa e pili ana i ke kūpaʻa ʻaʻahu nui o ke kaula uwea a me ka papa insulation.ʻO ka mea polyurethane i hoʻohana ʻia i nā kaula, i ʻike maʻamau ʻia ʻo TPU, he thermoplastic polyurethane elastomer rubber.Hoʻokaʻawale nui ʻia i ke ʻano polyester a me ke ʻano polyether, me ka laulā paʻakikī (60HA-85HD), ʻaʻahu kūpaʻa, kūpaʻa ʻaila, ʻike maopopo, a me ka elasticity maikaʻi.ʻAʻole wale ʻo TPU i ka pale lole kiʻekiʻe kiʻekiʻe, kiʻekiʻe kiʻekiʻe, kiʻekiʻe tensile ikaika, ʻoʻoleʻa a he kūʻokoʻa ʻo ia a he mea kūlohelohe kūlohelohe.
ʻO nā wahi noi o nā kaula polyurethane sheathed e pili ana i nā uwea noi moana, nā lopako ʻenehana a me nā kaula manipulator, nā mīkini awa a me nā kaula pahu pahu gantry crane, a me nā kaula mīkini ʻenekinia.
6. Uea sheath material: Thermoplastic CPE
Hoʻohana pinepine ʻia ka polyethylene chlorinated (CPE) i nā wahi ʻino loa.Loaʻa iā ia nā hiʻohiʻona o ke kaumaha māmā, paʻakikī loa, haʻahaʻa haʻahaʻa haʻahaʻa, kūʻē i ka aila maikaʻi, kūpaʻa wai maikaʻi, kūpaʻa kemika maikaʻi a me ka pale UV, a me ke kumu kūʻai haʻahaʻa.
7. Uila sheath mea: ceramic silicone rubber
He maikaʻi loa ka pale ʻana i ke ahi, ka pale ahi, ka uahi haʻahaʻa, nā mea ʻawaʻawa a me nā waiwai ʻē aʻe.He maʻalahi ke kaʻina hana extrusion.ʻO ke koena ma hope o ke puhi ʻana he pūpū seramika paʻakikī.ʻAʻole hoʻoheheʻe ʻia ka pūpū paʻakikī i kahi ahi ahi a ʻaʻole ʻo Dropping, hiki iā ia ke hele i ka hoʻāʻo pono o ka laina i kuhikuhi ʻia ma GB/T19216.21-2003 ma kahi mahana o 950 ℃-1000 ℃, ʻike ʻia i ke ahi no 90 mau minuke, a maloʻo. no 15 mau minuke.He kūpono ia no kēlā me kēia wahi e koi ai i ka pale ahi e hōʻoia i ka lawe ʻana i ka mana maʻemaʻe i ka wā o ke ahi.Ua pāʻani i kahi hana pale paʻa.
ʻAʻohe koi koʻikoʻi nā huahana silicone silicone no nā mea hana a maʻalahi ka ʻenehana hana.Hiki ke hoʻokō ʻia ka hana ʻana me ka hoʻohana ʻana i nā lako hana hoʻoponopono silicone maʻamau.Ke hoʻohālikelike ʻia me ka uea refractory o kēia manawa a me ka ʻenehana hana kelepona, ʻoi aku ka maikaʻi o ka hana ʻana a hiki ke hōʻemi i ka hoʻohana ʻana i ka ikehu a mālama i nā kumukūʻai.
ʻO ka mea i luna aʻe e pili ana i nā mea o nā kaula kaula.ʻO kaʻoiaʻiʻo, nui nā ʻano o nā kaula uwea.Ke koho ʻana i nā mea maka no nā sheath cable, pono e noʻonoʻo ʻia ka hoʻohālikelike o ka mea hoʻohui a me ka hoʻololi ʻana i ke kaiapuni.No ka la'ana, pono paha i ke kaiapuni anu loa i ke kaula uwea e ma'alahi i ka wela ha'aha'a loa.
