Polypropylene (PP), e le polasetiki e tloaelehileng, e na le litšoaneleho tse kang boima bo bobebe, mehloli e mengata ea lihlahisoa tse tala, theko e tlaase, khanyetso e ntle ea lik'hemik'hale, ho bōptjoa habonolo le ho sebelisoa hape. Leha ho le joalo, e na le mefokolo e kang matla a fokolang, ho hanyetsa mocheso o fokolang, ho senyeha ho hoholo ha shrinkage, khanyetso e fokolang ea creep, brittleness ea mocheso o tlaase, le ho hanyetsa mocheso le ho tsofala ha oksijene. Meeli ena e thibetse tšebeliso ea eona lits'ebetsong tsa cable. Bafuputsi ba 'nile ba sebetsa ho fetola thepa ea polypropylene ho ntlafatsa tshebetso ea bona ka kakaretso,' me mahlaseli a marang-rang a marang-rang a fetotsoeng polypropylene (XL-PP) a hlōtse mefokolo ena ka katleho.
Lithapo tse sirelelitsoeng tsa XL-PP li ka kopana le liteko tsa lelakabe la UL VW-1 le litekanyetso tsa terata tsa 150 ° C tsa UL. Lits'ebetsong tsa cable tse sebetsang, hangata EVA e kopantsoe le PE, PVC, PP, le lisebelisoa tse ling ho lokisa ts'ebetso ea lera la insulation cable.
E 'ngoe ea mefokolo ea PP e amanang le marang-rang ke hore e kenyelletsa karabelo ea tlholisano lipakeng tsa ho thehoa ha lihlopha tsa li-unsaturated qetellong ka karabelo ea ho senyeha le karabelo e hokahanyang lipakeng tsa limolek'hule tse hlohlellelitsoeng le li-radicals tse kholo tsa limolek'hule. Liphuputso li bonts'itse hore karo-karolelano ea ho senyeha ho ea ho karabelo e amanang le sefapano ho PP irradiation cross-linking e ka ba 0.8 ha o sebelisa mahlaseli a gamma-ray. Ho fihlella karabelo e sebetsang ea khokahano ea li-cross ho PP, ho hlokahala hore ho eketsoe batšehetsi ba li-cross-link bakeng sa ho hokahanya ha marang-rang. Ho phaella moo, botenya bo sebetsang ba ho hokahanya ha sefapano bo lekanyelitsoe ke bokhoni ba ho kenella ha maballo a elektronike nakong ea mahlaseli. Mahlaseli a lebisa ho hlahisoeng ha khase le ho phophoma, e leng molemo bakeng sa ho kopanya lihlahisoa tse tšesaane empa ho fokotsa tšebeliso ea likhoele tse teteaneng tse nang le marako.
(3) Cross-Linked Ethylene-Vinyl Acetate Copolymer (XL-EVA) Insulation Material:
Ha tlhokahalo ea polokeho ea lithapo e ntse e eketseha, nts'etsopele ea likhoele tse hokahaneng tse se nang mollo halogen tse se nang mollo tse sa sebetseng e eketsehile ka potlako. Ha e bapisoa le PE, EVA, e hlahisang vinyl acetate monomers ka har'a ketane ea limolek'hule, e na le kristale e tlase, e bakang ho feto-fetoha ha maemo, ho hanyetsa tšusumetso, ho lumellana ha li-filler, le thepa ea ho tiisa mocheso. Ka kakaretso, thepa ea resin ea EVA e itšetlehile ka litaba tsa vinyl acetate monomers ka ketane ea limolek'hule. Likahare tse phahameng tsa vinyl acetate li lebisa ponaletsong e eketsehileng, ho tenyetseha le maemo a thata. Resin ea EVA e na le khokahano e ntle ea li-filler le khokahano ea sefapano, e e etsa hore e tumme le ho feta likhoeleng tse hokahaneng tse se nang halogen tse se nang mollo.
Resin ea EVA e nang le vinyl acetate content ea hoo e ka bang 12% ho isa ho 24% e atisa ho sebelisoa ho kenya mohala le cable. Lits'ebetsong tsa 'nete tsa cable, hangata EVA e kopantsoe le PE, PVC, PP, le lisebelisoa tse ling ho lokisa ts'ebetso ea lera la insulation cable. Likarolo tsa EVA li ka khothaletsa ho hokahanya, ho ntlafatsa ts'ebetso ea cable kamora ho hokahanya.
(4) Cross-Linked Ethylene-Propylene-Diene Monomer (XL-EPDM) Insulation Material:
XL-EPDM ke terpolymer e entsoeng ka ethylene, propylene, le li-non-conjugated diene monomers, tse amanang le sefapano ka mahlaseli. Lithapo tsa XL-EPDM li kopanya melemo ea likhoele tsa polyolefin-insulated le likhoele tse tloaelehileng tse kentsoeng ka rabara:
1. Ho feto-fetoha ha maemo, ho ba le botsitso, ho se khomarelane ka mocheso o phahameng, ho hanyetsa botsofali nako e telele, le ho hanyetsa maemo a leholimo a thata (-60 ° C ho 125 ° C).
2. Ho hanyetsa Ozone, ho hanyetsa UV, ts'ebetso ea motlakase ea motlakase, le ho hanyetsa ho bola ha lik'hemik'hale.
3. Ho hanyetsa oli le li-solvents tse bapisoang le lisebelisoa tsa rabara tsa chloroprene ka kakaretso. E ka hlahisoa ho sebelisoa lisebelisoa tse tloaelehileng tse chesang tsa extrusion, e leng se etsang hore e be le chelete e ngata.
Lithapo tsa XL-EPDM-insulated li na le mefuta e mengata ea lisebelisoa, ho kenyelletsa empa li sa felle feela ho lithapo tsa motlakase tse tlaase, lithapo tsa likepe, lithapo tsa motlakase tsa likoloi, lithapo tsa taolo bakeng sa li-compressor tsa sehatsetsing, lithapo tsa mehala tsa meepo, lisebelisoa tsa ho cheka le lisebelisoa tsa bongaka.
Litšitiso tse ka sehloohong tsa lithapo tsa XL-EPDM li kenyelletsa ho hanyetsa ho lla ho fokolang le thepa e fokolang ea sekhomaretsi le ea ho iketsetsa, e ka amang ts'ebetso e latelang.
(5) Silicone Rubber Insulation Material
Rabara ea silicone e na le maemo a bonolo le e hanyetsanang hantle le ozone, ho tsoa ha corona le malakabe, e leng se etsang hore e be thepa e loketseng bakeng sa ho kenya motlakase. Tšebeliso ea eona ea mantlha indastering ea motlakase ke ea lithapo le likhoele. Lithapo tsa rabara tsa silicone le likhoele li loketse haholo ho sebelisoa maemong a mocheso o phahameng le a hlokang, 'me li phela nako e telele haholo ha li bapisoa le likhoele tse tloaelehileng. Lisebelisoa tse tloaelehileng li kenyelletsa li-motor tse nang le mocheso o phahameng, li-transformer, lijenereithara, thepa ea elektronike le ea motlakase, lithapo tse khantšang likoloing tsa lipalangoang, le mehala ea matla a leoatle le ea ho laola.
Hajoale, likhoele tsa silicone tse kentsoeng ka rabara hangata li hokahana ka ho sebelisa khatello ea sepakapaka ka moea o chesang kapa mouoane o nang le khatello e phahameng. Hape ho na le lipatlisiso tse tsoelang pele mabapi le ho sebelisa mahlaseli a electron beam bakeng sa rabara ea silicone e kopanyang sefapano, le hoja e e-s'o atamele indastering ea lithapo. Ka tsoelopele ea morao-rao ea mahlale a marang-rang a marang-rang a marang-rang, e fana ka mefuta e meng e theko e tlase, e sebetsang hantle, le e se nang tikoloho bakeng sa lisebelisoa tsa silicone tse kenyang rabara. Ka mabone a electron beam kapa mehloli e meng ea mahlaseli, ho hokahana hantle ha silicone rabara ho ka finyelloa ha ho ntse ho lumella taolo holim'a botebo le tekanyo ea ho hokahanya ho fihlela litlhoko tse khethehileng tsa kopo.
Ka hona, ts'ebeliso ea mahlale a marang-rang a marang-rang bakeng sa lisebelisoa tsa ho kenya rabara ea silicone e na le ts'episo e kholo indastering ea terata le likhoele. Theknoloji ena e lebelletsoe ho fokotsa litšenyehelo tsa tlhahiso, ho ntlafatsa katleho ea tlhahiso, le ho kenya letsoho ho fokotsa litlamorao tse mpe tsa tikoloho. Boiteko ba nakong e tlang ba lipatlisiso le nts'etsopele bo ka 'na ba tsoela pele ho khanna tšebeliso ea mahlale a marang-rang a marang-rang bakeng sa lisebelisoa tsa silicone tsa rabara, e leng se etsang hore li sebetse haholo bakeng sa ho etsa lithapo tse nang le mocheso o phahameng, lithapo tse sebetsang hantle le likhoele indastering ea motlakase. Sena se tla fana ka tharollo e tšepahalang le e tšoarellang bakeng sa libaka tse fapaneng tsa kopo.
