Lilemong tsa morao tjena, tlhoko ea lisebelisoa tsa cable tse se nang mosi o tlase (LSZH) e eketsehile ka lebaka la polokeho ea tsona le melemo ea tikoloho. E 'ngoe ea lisebelisoa tsa bohlokoa tse sebelisoang lithapong tsena ke polyethylene e kopantsoeng (XLPE).
1. Ke engPolyethylene e hokahaneng le sefapano (XLPE)?
Polyethylene e hokahaneng ka sefapano, eo hangata e khutsufatswang ka XLPE, ke thepa ea polyethylene e fetotsoeng ka ho eketsoa ha crosslinker. Ts'ebetso ena ea crosslinking e ntlafatsa thepa ea mocheso, mechine le lik'hemik'hale ea thepa, e leng se etsang hore e be e loketseng lits'ebetso tse fapaneng. XLPE e sebelisoa haholo lits'ebetsong tsa liphaephe tsa litšebeletso tsa kaho, lits'ebetsong tsa ho futhumatsa le ho pholisa ka mahlaseli a hydraulic, liphaephe tsa metsi tsa malapeng le ho kenya mocheso oa cable ea motlakase o phahameng.
2. Melemo ea ho kenya XLPE ka har'a insulation
Ho kenya thepa ka hare ho XLPE ho fana ka melemo e 'maloa ho feta thepa ea setso joalo ka polyvinyl chloride (PVC).
Melemo ena e kenyelletsa:
Ho tsitsa ha mocheso: XLPE e ka mamella mocheso o phahameng ntle le ho fetoha 'me ka hona e loketse lits'ebetso tsa khatello e phahameng.
Ho hanyetsa lik'hemik'hale: Sebopeho se hokahaneng se na le ho hanyetsa lik'hemik'hale ho babatsehang, ho netefatsa ho tšoarella libakeng tse thata.
Matla a mechini: XLPE e na le thepa e ntle ea mechini, ho kenyeletsoa le ho hanyetsa ho tsofala le ho petsoha ha khatello.
Ka hona, thepa ea cable ea XLPE e atisa ho sebelisoa likhokahanong tsa motlakase tsa kahare, li-lead tsa enjene, li-lead tsa mabone, lithapo tse nang le motlakase o phahameng ka hare ho likoloi tse ncha tsa matla, mela ea taolo ea matšoao a nang le motlakase o tlase, lithapo tsa terene, lithapo tsa terene e tsamaeang ka tlas'a lefatše, lithapo tsa tšireletso ea tikoloho ea merafo, lithapo tsa metsing, lithapo tsa ho kenya motlakase oa nyutlelie, lithapo tsa TV tse nang le motlakase o phahameng, lithapo tsa X-RAY tse nang le motlakase o phahameng le lithapo tsa phetisetso ea motlakase.
Theknoloji ea ho hokahanya polyethylene
Ho kopanya polyethylene ho ka finyelloa ka mekhoa e fapaneng, ho kenyeletsoa mahlaseli, peroxide le silane crosslinking. Mokhoa o mong le o mong o na le melemo ea oona 'me o ka khethoa ho latela litlhoko tse itseng tsa ts'ebeliso. Tekanyo ea ho kopanya e ama haholo litšobotsi tsa thepa. Ha bongata ba crosslinking bo le holimo, litšobotsi tsa mocheso le tsa mechine li ba betere.
3. Ke enghalogen e se nang mosi o tlase (LSZH)thepa?
Lisebelisoa tse se nang halogen tse nang le mosi o tlase (LSZH) li entsoe ka tsela eo likhoele tse pepesehetseng mollong li lokollang mosi o fokolang ha li cha 'me li se ke tsa hlahisa mosi o chefo oa halogen. Sena se etsa hore li lokele haholoanyane ho sebelisoa libakeng tse koetsoeng le libakeng tse nang le moea o fokolang, joalo ka lithanele, marang-rang a literene tse ka tlas'a lefatše le mehahong ea sechaba. Likhoele tsa LSZH li entsoe ka metsoako ea thermoplastic kapa thermoset 'me li hlahisa maemo a tlase haholo a mosi le mosi o chefo, ho netefatsa hore ho bonahala hantle le ho fokotsa likotsi tsa bophelo nakong ea mollo.
4. Tšebeliso ea thepa ea cable ea LSZH
Lisebelisoa tsa cable tsa LSZH li sebelisoa lits'ebetsong tse fapaneng moo matšoenyeho a polokeho le tikoloho a leng bohlokoa.
Tse ling tsa lits'ebetso tsa bohlokoa li kenyelletsa:
Thepa ea thapo bakeng sa mehaho ea sechaba: Lithapo tsa LSZH li sebelisoa hangata mehahong ea sechaba joalo ka boema-fofane, liteishene tsa literene le lipetlele ho netefatsa polokeho nakong ea mollo.
Likhoele tsa lipalangoang: Likhoele tsena li sebelisoa likoloing, lifofaneng, likoloing tsa terene le likepeng ho fokotsa kotsi ea mosi o chefo haeba ho ka ba le mollo.
Likhoele tsa marangrang a terene ea thanele le ea ka tlas'a lefatše: Likhoele tsa LSZH li na le litšobotsi tse fokolang tsa mosi le halogen, e leng se etsang hore li be ntle bakeng sa tšebeliso marangrang a terene ea thanele le ea ka tlas'a lefatše.
Lithapo tsa Sehlopha sa B1: Lisebelisoa tsa LSZH li sebelisoa lithapong tsa Sehlopha sa B1, tse etselitsoeng ho fihlela maemo a thata a polokeho ea mollo 'me li sebelisoa mehahong e melelele le meralong e meng ea motheo ea bohlokoa.
Tsoelo-pele ea morao tjena theknolojing ea XLPE le LSZH e shebane le ho ntlafatsa ts'ebetso ea thepa le ho atolosa lits'ebetso tsa eona. Lintho tse ncha li kenyelletsa nts'etsopele ea polyethylene e kopantsoeng ka bongata (XLHDPE), e nang le khanyetso e matlafalitsoeng ea mocheso le ho tšoarella.
Lisebelisoa tse feto-fetohang le tse tšoarellang, tse hokahaneng ka cross-linked polyethylene (XLPE) le lisebelisoa tsa cable tse nang le mosi o tlase oa zero-halogen (LSZH) li sebelisoa haholo liindastering tse fapaneng ka lebaka la thepa ea tsona e ntle ea mocheso, lik'hemik'hale le mechine. Ts'ebeliso ea tsona e ntse e hola ka tsoelo-pele e tsoelang pele ea theknoloji le tlhoko e ntseng e eketseha ea lisebelisoa tse sireletsehileng le tse mosa tikolohong.
Ha tlhoko ea lisebelisoa tsa cable tse tšepahalang le tse sireletsehileng e ntse e eketseha, ho lebeletsoe hore XLPE le LSZH li tla bapala karolo ea bohlokoa ho fihlelleng litlhoko tsena.
