I-PE Physically Foamed Insulation Compounds
Intshayelelo yeMveliso
Ngophuhliso oluqhubekayo lothungelwano lothungelwano kunye nokuphuculwa okuqhubekayo kwe-bandwidth yothumelo, iintambo zedatha ezisetyenziswa kuthungelwano lothungelwano nazo zihlala ziphuhlisa ukuya kwi-bandwidth ephezulu yothumelo. Okwangoku, i-Cat.6A kunye neentambo zedatha eziphezulu ziye zaba yimveliso eqhelekileyo ye-network cabling. Ukufezekisa ukusebenza ngcono kothumelo, ezo ntambo zedatha kufuneka zamkele ukugquma amagwebu.
Iikhompawundi zokugquma amagwebu enziwe ngomzimba we-PE yimathiriyeli yentambo yokugquma eyenziwe nge-resin ye-HDPE njengesiseko sezinto, ukongeza inani elifanelekileyo le-agent ye-nucleating kunye nezinye izongezo, kwaye zicutshungulwe ngokuxuba, iplastiki, kunye negranulating.
Ifanelekile ukwamkela itekhnoloji yogwebu ngokwasemzimbeni eyinkqubo yokutofa igesi engasebenziyo ecinezelekileyo (N2 okanye i-CO2) kwiplastiki ye-PE etyhidiweyo ukwenza igwebu leseli evaliweyo. Xa kuthelekiswa ne-PE eqinile, emva kokuba i-foam, i-dielectric constant of material iya kuncipha; inani lezinto eziphathekayo liyancitshiswa, kwaye ixabiso liyancitshiswa; ubunzima buyancipha; kwaye ubushushu bokufudumala buqiniswa.
Iikhompawundi ze-OW3068/F esizibonelelayo zizinto ezigqumayo ezinogwebu ngokwasemzimbeni ezisetyenziselwa ngokukodwa ukuveliswa kwedatha ye-cable cable layer insulation. Inkangeleko yayo yi-cylindrical compounds etyheli ekhanyayo enobukhulu be (φ2.5mm～φ3.0mm)×(2.5mm～3.0mm).
Ngexesha lenkqubo yokuvelisa, idigri ye-foaming yezinto eziphathekayo inokulawulwa yindlela yenkqubo, kwaye idigri ye-foaming inokufikelela malunga ne-70%. Iidigri ezahlukeneyo zogwebu zinokufumana ii-dielectric constants ezahlukeneyo, ukwenzela ukuba iimveliso zekhebula zedatha zikwazi ukufikelela ekuthotyweni okuphantsi, izinga eliphezulu losulelo, kunye nokusebenza ngcono kokuhanjiswa kombane.
Intambo yedatha eveliswe yi-OW3068/F PE yethu ye-foamed insulating compounds inokuhlangabezana neemfuno ze-IEC61156, ISO11801, EN50173 kunye neminye imigangatho.
iimpawu
Iikhompawundi zokugquma amagwebu ze-PE kwiintambo zedatha esizinikezelayo zinezi mpawu zilandelayo:
1) Ubungakanani besuntswana obufanayo obungenabumdaka;
I-2) Ifanelekile kwi-high-speed insulation extruding, isantya esikhuphayo sinokufikelela ngaphezu kwe-1000m / min;
3) Ngeempawu ezibalaseleyo zombane. I-dielectric constant izinzileyo kwii-frequencies ezahlukeneyo, i-dielectric loss tangent incinci, kwaye i-resistivity yevolumu inkulu, enokuqinisekisa ukuzinza kunye nokuhambelana kokusebenza ngexesha lokuhanjiswa kwe-high-frequency;
4) Ngeempawu ezigqwesileyo zomatshini, okungekho lula ukucudiswa kunye nokukhubazeka ngexesha lokukhupha kunye nokucubungula okulandelayo.
Isicelo
Kufanelekile ukuveliswa komgca we-foam we-insulated core wire of Cat.6A, Cat.7, Cat.7A kunye neCat.8 data cable.
