Ikhebula leminyaka engama-70 yobomi obudeifanelekile kuzo zonke iindawo ezinabemi abaxineneyo, njengeevenkile zokuthenga, iithiyetha, izikhululo, izikhululo zeenqwelo moya kunye nezinye iindawo zikawonke-wonke, kunye nemigca ebalulekileyo yokuhambisa, iingcingo zokwakha, ukuhombisa ikhaya, njl.
Ubomi benkonzo yale mveliso abukho ngaphantsi kweminyaka engama-70 kumyinge wobushushu wokusebenza wama-70°C.Ukushisa okuvumelekileyo kwexesha elide lokusebenza kwe-cable conductor yi-90 ° C, 105 ° C, kunye ne-125 ° C;ubushushu obuphezulu bokusebenza ngexesha lesiphaluka esifutshane (elona xesha liphezulu 5S) yi-250°C.
Intambo yokugquma intambo ithatha i-radiation cross-linked double-layer insulation structure.I-insulation yangaphakathi idibana nokusebenza kwe-insulation yombane, i-insulation yangaphandle idibana nokusebenza kwe-flame retardant, kunye nemigangatho yangaphakathi nangaphandle ngaxeshanye idibana nokusebenza okuphezulu kobomi.
Izizathu kunye neenzuzo zokusebenzisa i-radiation cross-linking for insulation (xa kuthelekiswa ne-PVC eqhelekileyo): Izinto zePVC zeMveli zinozinzo olubi lwe-thermal.
Iba nzima kwaye i-brittle kumaqondo aphantsi, kwaye ilula ngokulula kwaye iphumle kumaqondo aphezulu.Inokumelana nempembelelo embi kunye nokumelana nokuguga, ikhupha ngokulula iigesi eziyingozi kumaqondo aphezulu obushushu, kwaye iwisa ngokulula izinto eziyingozi ngexesha lokuvelisa kunye nokusetyenziswa, okubangela iziphumo ezibi ebantwini nakwimekobume.
I-radiation cross-linking isebenzisa imiqadi ye-electron ene-energy ephezulu eveliswa yi-electron accelerators ukuguqula i-original chain-like molecular structure ibe yi-three-dimensional network ye-molecular structure ukwenza i-cross-link.
Isakhiwo se-molecular network ye-three-dimensional inozinzo oluhle lwe-thermal, kwaye i-insulation, i-electric and mechanical properties iphuculwe.Uphuculo olubonakalayo.
Iinzuzo eziphambili zokusebenza zezi zilandelayo
Ubomi bekhebula bungqamaniswa nesakhiwo: iminyaka engama-70.Ngenxa yezinga eliphezulu lokumelana nokushisa kunye nokushisa okuphezulu kokuguga kwe-irradiation cross-linked insulation, ubomi benkonzo yentambo eyenza ukushisa ngexesha lokusetyenziswa kwandiswa.
Umthamo omkhulu wokuthwala: i-irradiation cross-linked cable inyuka ukusuka kwi-non-cross-link 70 ° C ukuya kwi-90 ° C, 105 ° C, kunye ne-125 ° C.
Ukuxhathisa okukhulu kwe-insulation: Ekubeni i-radiation cross-linking igwema ukusetyenziswa kwe-hydroxide njenge-flame retardant, ikhusela ukudibanisa kwangaphambili ngexesha lokudibanisa kunye nokunciphisa ukuxhathisa kwe-insulation ngenxa yokufunxa ukufuma emoyeni ngumaleko we-insulation.Oku kuqinisekisa ixabiso lokumelana ne-insulation.
Umgangatho wemveliso ezinzileyo: Umgangatho weentambo ze-silane ezinqamlezileyo ezinqamlezileyo (ezaziwa ngokuba ziintambo zamanzi afudumeleyo) zichatshazelwa bubushushu bamanzi, inkqubo yokukhutshwa, izongezo ezidibanisa umnqamlezo kunye nezinye izinto, kwaye umgangatho awuzinzile, ngelixa umgangatho wokuwela umbane. -iintambo eziqhagamshelweyo zixhomekeke kwi-electron beam.Idosi ye-irradiation ilawulwa yikhompyutheni, enciphisa izinto zabantu, ngoko umgangatho uzinzile.
I-retardant ephezulu yomlilo: Kusetyenziswa izixhobo eziphezulu ze-flame retardant, kwaye i-ZA, i-ZB, i-ZC, kunye neentambo zingayilwa ngokweemfuno zabathengi.Ukusebenza kwe-flame retardant kuphumelele uvavanyo lokutshisa oluchazwe kwi-GB / T 1966-2005.
I-halogen-free, ityhefu ephantsi, umsi ophantsi: ubuncinane bokuhanjiswa kokukhanya kwiklasi yokuqala yodidi lweingcingo ezikwazi ukumelana nomlilo kunye neengcingo zodidi lokuqala ezikwaziyo ukumelana nomlilo azikho ngaphantsi kwe-80%, kwaye ubuncinci bokugqithisela kwezinye iingcingo xa kutshiswa akukho ngaphantsi. ngaphezu kwe-60%.Ixabiso le-acidity PH yegesi evuthayo ayiyi kuba ngaphantsi kwe-4.3, kwaye i-conductivity ayiyi kuba nkulu kune-10us / mm.
