I-polyethylene edibeneyoUkugqunyelelwa kwenziwa ngemichiza okanye iindlela zomzimba ukuguqula imolekyuli ye-polyethylene ukusuka kwisakhiwo semolekyuli ukuya kwisakhiwo sothungelwano esinamacala amathathu, ukusuka kwisixhobo se-thermoplastic ukuya kwisixhobo se-thermosetting, kunye nokunyusa ubushushu bokusebenza ukusuka kwi-70 ℃ ukuya kwi-90 ℃, ephucula kakhulu ukusebenza kwezinto. .
I-polyethylene edibeneyoinezi nzuzo zilandelayo.
1, ukusebenza ukumelana nobushushu;I-XLPE ene-three-dimensional mesh structure inomsebenzi ogqwesileyo wokumelana nobushushu.Ayiyi kuchithwa kwaye i-carbonize phantsi kwe-200 ° C.
Ubushushu bokusebenza bexesha elide linokufikelela kwi-90℃, kwaye ubomi bobushushu bufikelela kwiminyaka engama-40.
I-2, Ukusebenza kwe-Insulation: I-XLPE igcina iimpawu zokugquma ezilungileyo zokuqala ze-PE, kwaye ukuxhathisa ukugquma kuyanda.Idielectric yayo
Ixabiso le-dielectric loss angle tangent lincinci kakhulu, kwaye alichatshazelwa kakhulu ngubushushu.
I-3, iipropathi zeMechanical: Ngenxa yokusekwa kweebhondi ezintsha zeekhemikhali phakathi kwee-macromolecules, ukuqina, ukuqina, ukuxhathisa ukunxiba kunye nokuchasana kwempembelelo ye-XLPE kuyaphuculwa.
Ubunzima, ukuqina, ukuxhathisa kwe-abrasion kunye nokuchasana kwempembelelo ye-XLPE kuphuculwe ngenxa yokusekwa kweebhondi ezintsha zeekhemikhali phakathi kwe-macromolecules, ngaloo ndlela kuhlawulela iintsilelo ze-PE eziqhekezwa ngokulula ngoxinzelelo lwendalo.
I-4, Ukumelana nemichiza: I-XLPE ine-asidi eqinile kunye nokumelana ne-alkali kunye nokuxhathisa kweoli, kunye neemveliso zayo zokutsha ikakhulu ngamanzi kunye ne-carbon dioxide.
Ayinabungozi kangako kwimo engqongileyo kwaye ihlangabezana neemfuno zokhuseleko lomlilo lwanamhlanje.
