Lilemong tsa morao tjena, tlhokahalo ea lisebelisoa tsa cable tse se nang mosi o tlase oa halogen (LSZH) e eketsehile ka lebaka la polokeho ea tsona le melemo ea tikoloho. E 'ngoe ea lisebelisoa tsa bohlokoa tse sebelisoang likhoeleng tsena ke crosslinked polyethylene (XLPE).
1. Ke engPolyethylene e kopantsoeng ka sefapano (XLPE)?
Polyethylene e kopantsoeng ka sefapano, e atisang ho khutsufatsoa XLPE, ke thepa ea polyethylene e fetotsoeng ka ho eketsoa ha crosslinker. Ts'ebetso ena ea ho kopanya lifapano e ntlafatsa thepa ea mocheso, ea mechine le ea lik'hemik'hale, e etsa hore e be e loketseng bakeng sa mefuta e sa tšoaneng ea likopo. XLPE e sebelisoa haholo meahong ea lits'ebeletso tsa lipeipi tsa lits'ebeletso, ho futhumatsa le ho futhumatsa ha hydraulic radiant system, lipeipi tsa metsi tsa malapeng le ho kenya lithapo tse phahameng tsa motlakase.
2. Melemo ea XLPE insulation
XLPE insulation e fana ka melemo e mengata ho feta lisebelisoa tsa setso tse kang polyvinyl chloride (PVC).
Melemo ena e kenyelletsa:
Thermal botsitso: XLPE e khona ho mamella mocheso o phahameng ntle le deformation mme ka hona e loketse lits'ebetso tse phahameng tsa khatello.
Khanyetso ea lik'hemik'hale: Mohaho o kopantsoeng o na le khanyetso e ntle ea lik'hemik'hale, e netefatsang ho tšoarella libakeng tse thata.
Matla a mochini: XLPE e na le thepa e ntle haholo ea mochini, ho kenyelletsa ho hanyetsa ho roala le khatello ea maikutlo.
Ka hona, lisebelisoa tsa cable tsa XLPE hangata li sebelisoa likhokahanong tsa motlakase tsa kahare, li-motor lead, lithapo tsa mabone, lithapo tse nang le motlakase o mongata ka har'a likoloi tse ncha tsa matla, likhoele tsa taolo ea mats'oao a tlase, lithapo tsa locomotive, likhoele tsa metro, meepo ea ts'ireletso ea tikoloho, likhoele tsa Marine, nyutlelie. lithapo tse behang motlakase, lithapo tsa TV tse nang le matla a phahameng a motlakase, lithapo tsa X-RAY tse nang le matla a phahameng le likhoele tse tsamaisang motlakase.
Polyethylene crosslinking theknoloji
Crosslinking ea polyethylene ka finyelloang ka mekhoa e sa tšoaneng, ho akarelletsa le mahlaseli, peroxide le silane crosslinking. Mokhoa o mong le o mong o na le melemo ea oona mme o ka khethoa ho latela litlhoko tse khethehileng tsa kopo. Tekanyo ea crosslinking e ama haholo thepa ea thepa. Ha matla a crosslinking a phahame, a ntlafatsa thepa ea mocheso le ea mechine.
3. Ke englow-smoke halogen-free (LSZH)thepa?
Lisebelisoa tse se nang mosi o tlase oa halogen (LSZH) li etselitsoe hore lithapo tse pepeselitsoeng mollong li lokolle mosi o fokolang ha li tuka 'me li se ke tsa hlahisa mosi o chefo oa halogen. Sena se etsa hore li tšoanelehe haholoanyane ho sebelisoa Libakeng tse koaletsoeng le libakeng tse nang le moea o fokolang, joalo ka lithanele, marang-rang a literene tse ka tlas'a lefatše le meaho ea sechaba. Lithapo tsa LSZH li entsoe ka metsoako ea thermoplastic kapa thermoset mme li hlahisa maemo a tlase haholo a mosi le mosi o chefo, ho netefatsa ponahalo e ntle le ho fokotsa likotsi tsa bophelo nakong ea mollo.
4. Sesebelisoa sa lisebelisoa tsa cable ea LSZH
Lisebelisoa tsa cable tsa LSZH li sebelisoa lits'ebetsong tse fapaneng moo ho amehang ts'ireletso le tikoloho.
Lisebelisoa tse ling tsa bohlokoa li kenyelletsa:
Lisebelisoa tsa cable bakeng sa mehaho ea sechaba: Lithapo tsa LSZH li atisa ho sebelisoa mehahong ea sechaba e kang lifofane, liteishene tsa terene le lipetlele ho netefatsa tšireletso nakong ea mollo.
Lithapo tsa lipalangoang: Lithapo tsena li sebelisoa likoloing, lifofaneng, likoloing tsa literene le likepeng ho fokotsa kotsi ea mosi o chefo ha ho ka ba le mollo.
Lithapo le likhoele tsa marang-rang tsa terene ea ka tlas'a lefatše: Lithapo tsa LSZH li na le mosi o fokolang le litšobotsi tse se nang halogen, tse etsang hore e be tse loketseng ho sebelisoa kotopong le marang-rang a terene a ka tlas'a lefatše.
Lithapo tsa Sehlopha sa B1: Lisebelisoa tsa LSZH li sebelisoa lithapo tsa Sehlopha sa B1, tse etselitsoeng ho finyella litekanyetso tse thata tsa tšireletso ea mollo 'me li sebelisoa mehahong e melelele le lisebelisoa tse ling tsa bohlokoa.
Lintlafatso tsa morao-rao tsa theknoloji ea XLPE le LSZH li tsepamisitse maikutlo ho ntlafatseng ts'ebetso ea thepa le ho holisa lits'ebetso tsa eona. Litlhahiso li kenyelletsa nts'etsopele ea polyethylene (XLHDPE) ea high-density cross-linked, e matlafalitseng ho hanyetsa mocheso le ho tšoarella.
Lisebelisoa tse feto-fetohang le tse tšoarellang, tse amanang le sefapano sa polyethylene (XLPE) le lisebelisoa tsa cable tse tlaase tsa zero-halogen (LSZH) li sebelisoa haholo liindastering tse sa tšoaneng ka lebaka la thepa ea tsona e ntle ea mocheso, lik'hemik'hale le tsa mechine. Likopo tsa bona li ntse li tsoela pele ho hola ka tsoelo-pele e tsoelang pele ea theknoloji le tlhokahalo e ntseng e eketseha ea lisebelisoa tse sireletsehileng le tse baballang tikoloho.
Ha tlhoko ea lisebelisoa tsa cable tse tšepahalang le tse bolokehileng li ntse li eketseha, XLPE le LSZH li lebelletsoe ho bapala karolo ea bohlokoa ho fihlela litlhoko tsena.
