Ukusetyenziswa kweziXhobo zeCable zeHalogen ezingenamsi ophantsi kunye nePolyethylene edityaniswe ngokunqamlezileyo (XLPE) kwiMathiriyeli yeCable

Kwiminyaka yakutshanje, imfuno yezixhobo zentambo ze-halogen-free (LSZH) eziphantsi komsi (LSZH) ziye zanda ngenxa yokhuseleko kunye neenzuzo zokusingqongileyo. Enye yezinto eziphambili ezisetyenziswe kwezi ntambo yi-polyethylene edibeneyo (XLPE).

1. YintoniI-Polyethylene edityaniswe ngokunqamlezileyo (XLPE)?

I-polyethylene edibeneyo yoMnqamlezo, ehlala ifinyeziwe i-XLPE, yinto ye-polyethylene eguqulelwe ngokudibanisa i-crosslinker. Le nkqubo yokudibanisa i-cross-link iphakamisa i-thermal, i-mechanical kunye ne-chemical properties of the material, iyenza ibe yinto efanelekileyo kwiintlobo ezahlukeneyo zezicelo. I-XLPE isetyenziswa kakhulu kulwakhiwo lweenkonzo zemibhobho, iinkqubo zokufudumeza ezikhazimlayo zehydraulic kunye nezokupholisa, imibhobho yamanzi asekhaya kunye nokufakelwa kwentambo yombane ophezulu wombane.

2. Izinto eziluncedo zokugquma kweXLPE

Ukugquma kwe-XLPE kunika iingenelo ezininzi ngaphezu kwemathiriyeli yemveli efana ne-polyvinyl chloride (PVC).
Ezi zinto ziluncedo ziquka:
Ukuzinza kwe-Thermal: I-XLPE inokumelana nokushisa okuphezulu ngaphandle kokuguqulwa kwaye ngoko ifanelekile kwizicelo zoxinzelelo oluphezulu.
Ukumelana nemichiza: Isakhiwo esinqamlekileyo sinokuchasana kweekhemikhali, siqinisekisa ukuqina kwiindawo ezinzima.
Amandla omatshini: I-XLPE ineempawu ezibalaseleyo zoomatshini, kubandakanya ukuchasa ukunxiba kunye nokuqhekeka koxinzelelo.
Ke ngoko, izixhobo zentambo ze-XLPE zihlala zisetyenziswa kuqhagamshelo lombane lwangaphakathi, iintambo zombane, iintambo zokukhanya, iingcingo eziphezulu zombane ngaphakathi kwezithuthi zamandla amatsha, imigca yokulawula imiqondiso ephantsi-voltage, iingcingo ezihamba ngololiwe, iintambo ezingaphantsi kwendlela, iintambo zokukhusela imigodi, iintambo zaselwandle, iintambo zenyukliya. iintambo zokubeka amandla, iintambo zeTV ezinevoltage ephezulu, iintambo zeX-RAY ezinombane ophezulu kunye neentambo zothumelo lombane.
Polyethylene crosslinking iteknoloji

I-crosslinking ye-polyethylene inokufezekiswa ngeendlela ezahlukeneyo, kubandakanywa imitha, i-peroxide kunye ne-silane crosslinking. Indlela nganye ineenzuzo zayo kwaye inokukhethwa ngokweemfuno ezithile zesicelo. Iqondo le-crosslinking lichaphazela kakhulu iimpawu zezinto eziphathekayo. Ukuphakama kwe-crosslinking density, ngcono i-thermal kunye ne-mechanical properties.

3. YintoniUmsi ophantsi wehalogen-free (LSZH)izixhobo?

Izinto ezinomsi ophantsi we-halogen-free (LSZH) ziyilelwe ukuba iintambo ezivezwe emlilweni zikhuphe umsi omncinci xa utshisa kwaye zingavelisi umsi onetyhefu we-halogen. Oku kubenza bafaneleke ngakumbi ukusetyenziswa kwiZithuba ezivaliweyo kunye neendawo ezinomoya ongemhle, njengamatonela, uthungelwano lukaloliwe oluphantsi komhlaba kunye nezakhiwo zikawonke-wonke. Iintambo ze-LSZH zenziwe ngeekhompawundi ze-thermoplastic okanye ze-thermoset kwaye zivelise amanqanaba aphantsi kakhulu omsi kunye nomsi onetyhefu, ukuqinisekisa ukubonakala okungcono kunye nokunciphisa ingozi yempilo ngexesha lomlilo.

4. Isicelo sezinto zentambo ye-LSZH

Izinto zekhebula ze-LSZH zisetyenziswa kwiintlobo ezahlukeneyo zezicelo apho ukhuseleko kunye nokukhathazeka kokusingqongileyo kubaluleke kakhulu.
Ezinye izicelo eziphambili ziquka:
Izinto zekhebula zezakhiwo zikawonkewonke: Iintambo ze-LSZH zisetyenziswa ngokuqhelekileyo kwizakhiwo zikawonke-wonke ezifana neenqwelo-moya, izikhululo zikaloliwe kunye nezibhedlele ukuqinisekisa ukhuseleko ngexesha lomlilo.
Iintambo zothutho: Ezi ntambo zombane zisetyenziswa ezimotweni, kwinqwelo-moya, kwiimoto zikaloliwe nakwiinqanawe ukuze kuncitshiswe umngcipheko womphunga oyityhefu xa kuthe kwatsha.
Itonela kunye neentambo zothungelwano zikaloliwe ongaphantsi komhlaba: Iintambo ze-LSZH zinomsi ophantsi kunye neempawu ezingenayo i-halogen, ezizenza zilungele ukusetyenziswa kwitonela kunye nothungelwano lukaloliwe olungaphantsi komhlaba.
Iintambo zeKlasi ye-B1: Izinto ze-LSZH zisetyenziselwa iintambo zeKlasi B1, ezenzelwe ukuhlangabezana nemigangatho engqongqo yokhuseleko lomlilo kwaye zisetyenziswe kwizakhiwo ezide kunye nezinye iziseko ezibalulekileyo.

Inkqubela phambili yamva nje kwi-XLPE kunye ne-LSZH iteknoloji igxile ekuphuculeni ukusebenza kwezinto kunye nokwandisa izicelo zayo. Izinto ezintsha zibandakanya ukuphuhliswa kwe-polyethylene ephezulu edibeneyo (i-XLHDPE), eye yandisa ukuxhathisa ukushisa kunye nokuqina.

Izinto eziguquguqukayo kunye nezizinzileyo, ezinqamlezileyo ze-polyethylene (XLPE) kunye ne-low-smoke zero-halogen (LSZH) izixhobo zekhebula zisetyenziswa ngokubanzi kumashishini ahlukeneyo ngenxa yeempawu zabo ezintle kakhulu zokushisa, iikhemikhali kunye nezomatshini. Izicelo zabo ziyaqhubeka nokukhula ngokuqhubela phambili kwetekhnoloji kunye nemfuno eyandayo yezinto ezikhuselekileyo nezilungele ukusingqongileyo.

Njengoko imfuno yezinto ezithembekileyo nezikhuselekileyo zekhebula ziqhubeka zikhula, i-XLPE kunye ne-LSZH kulindeleke ukuba idlale indima ebalulekileyo ekuhlangabezaneni nezi mfuno.
