Ukusetyenziswa kwezixhobo zekhebula ezingenamsi ophantsi kunye nezixhobo zekhebula zePolyethylene (XLPE) ezidityaniswe neCross-linked

Kwiminyaka yakutshanje, imfuno yezinto zekhebula ezingenamsi omninzi (LSZH) inyukile ngenxa yokhuseleko lwazo kunye neenzuzo zokusingqongileyo. Enye yezinto eziphambili ezisetyenziswa kwezi ntambo yi-crosslinked polyethylene (XLPE).

1. YintoniI-Polyethylene edityanisiweyo (XLPE)?

I-polyethylene edityanisiweyo, edla ngokufinyezwa ngokuthi yi-XLPE, yinto eyenziwe nge-polyethylene eguqulwe ngokongezwa kwe-crosslinker. Le nkqubo yokudibanisa iphucula iipropati zobushushu, zoomatshini nezekhemikhali zezinto, nto leyo eyenza ukuba zilungele ukusetyenziswa ngeendlela ezahlukeneyo. I-XLPE isetyenziswa kakhulu kwiinkqubo zenkonzo yokwakha imibhobho, iinkqubo zokufudumeza nokupholisa ezisebenzisa i-hydraulic radiant, imibhobho yamanzi yasekhaya kunye nokufakelwa kwentambo yombane ophezulu.

2. Iingenelo zokufakelwa kwe-XLPE

Ukufakwa kwe-XLPE kunika iingenelo ezininzi ngaphezu kwezinto zemveli ezifana ne-polyvinyl chloride (PVC).
Ezi zibonelelo ziquka:
Uzinzo lobushushu: I-XLPE inokumelana nobushushu obuphezulu ngaphandle kokuguquka kwaye ke ngoko ifanelekile ukusetyenziswa koxinzelelo oluphezulu.
Ukumelana neekhemikhali: Isakhiwo esidityanisiweyo sinokumelana neekhemikhali okugqwesileyo, okuqinisekisa ukuqina kwiindawo ezirhabaxa.
Amandla oomatshini: I-XLPE ineempawu ezintle kakhulu zoomatshini, kubandakanya ukumelana nokuguguleka kunye nokuqhekeka koxinzelelo.
Ngoko ke, izixhobo zekhebula ze-XLPE zihlala zisetyenziswa kwiintambo zombane zangaphakathi, iileyidi zeemoto, iileyidi zokukhanyisa, iintambo ze-voltage ephezulu ngaphakathi kwezithuthi ezintsha zamandla, imigca yokulawula isignali ye-voltage ephantsi, iintambo ze-locomotive, iintambo ze-subway, iintambo zokukhusela okusingqongileyo kwemigodi, iintambo zaselwandle, iintambo zokubeka umbane wenyukliya, iintambo zeTV ze-voltage ephezulu, iintambo ze-X-RAY eziphezulu kunye neentambo zokuhambisa umbane.
Itekhnoloji yokudibanisa i-polyethylene

Ukudibanisa i-polyethylene kunokufezekiswa ngeendlela ezahlukeneyo, kubandakanya i-radiation, i-peroxide kunye ne-silane crosslinking. Indlela nganye ineenzuzo zayo kwaye inokukhethwa ngokweemfuno ezithile zesicelo. Umgangatho wokudibanisa uchaphazela kakhulu iimpawu zezinto. Okukhona uxinano lokudibanisa luphezulu, kokukhona iimpawu zobushushu nezoomatshini zingcono.

3. Zithinii-halogen engenamsi uphantsi (LSZH)izixhobo?

Izinto ezingenayo i-halogen enomsi omncinci (LSZH) zenzelwe ukuba iintambo ezivezwe emlilweni zikhuphe umsi omncinci xa zitsha kwaye zingavelisi umsi onetyhefu we-halogen. Oku kuzenza zifaneleke ngakumbi ukusetyenziswa kwiindawo ezivalekileyo nakwiindawo ezinomoya ophantsi, njengeetonela, uthungelwano lwezitimela ezingaphantsi komhlaba kunye nezakhiwo zikawonke-wonke. Iintambo ze-LSZH zenziwe ngeekhompawundi ze-thermoplastic okanye ze-thermoset kwaye zivelisa amanqanaba aphantsi kakhulu omsi kunye nomsi onetyhefu, okuqinisekisa ukubonakala okungcono kunye nokunciphisa iingozi zempilo ngexesha lomlilo.

4. Ukusetyenziswa kwezinto zekhebula ze-LSZH

Izixhobo zekhebula ze-LSZH zisetyenziswa kwiindlela ezahlukeneyo zokusebenza apho inkxalabo yokhuseleko kunye nokusingqongileyo ibaluleke kakhulu.
Ezinye zezicelo eziphambili ziquka:
Izixhobo zekhebula zezakhiwo zikawonke-wonke: Iintambo ze-LSZH zisetyenziswa rhoqo kwizakhiwo zikawonke-wonke ezifana nezikhululo zeenqwelo-moya, izikhululo zikaloliwe kunye nezibhedlele ukuqinisekisa ukhuseleko ngexesha lomlilo.
Iintambo zothutho: Ezi ntambo zisetyenziswa kwiimoto, kwiinqwelomoya, kwiimoto zoololiwe nakwiinqanawa ukunciphisa umngcipheko womsi onobuthi xa kutsha.
Iintambo zenethiwekhi yesitishi semijelo kunye neyomzila ongaphantsi komhlaba: Iintambo zeLSZH zineempawu ezincinci zomsi kunye ne-halogen, nto leyo eyenza ukuba zilungele ukusetyenziswa kwisitishi semijelo kunye nomzila ongaphantsi komhlaba.
Iintambo zeKlasi B1: Izixhobo zeLSZH zisetyenziswa kwiintambo zeKlasi B1, ezenzelwe ukuhlangabezana nemigangatho yokhuseleko lomlilo engqongqo kwaye zisetyenziswa kwizakhiwo ezinde nakwezinye iziseko ezibalulekileyo.

Inkqubela phambili yakutshanje kwitekhnoloji ye-XLPE kunye ne-LSZH igxile ekuphuculeni ukusebenza kwezixhobo kunye nokwandisa ukusetyenziswa kwazo. Izinto ezintsha ziquka uphuhliso lwe-polyethylene edibeneyo ene-high-density cross-linked (XLHDPE), enokumelana nobushushu kunye nokuqina.

Izixhobo ze-polyethylene (XLPE) ezisetyenziswa ngeendlela ezahlukeneyo nezihlala ixesha elide kunye nezixhobo zekhebula ze-low-smoke ze-zero-halogen (LSZH) zisetyenziswa kakhulu kumashishini ahlukeneyo ngenxa yeempawu zazo ezibalaseleyo zobushushu, iikhemikhali kunye nezoomatshini. Ukusetyenziswa kwazo kuyaqhubeka nokukhula ngokuqhubekeka kobuchwepheshe kunye nemfuno ekhulayo yezixhobo ezikhuselekileyo nezinobuhlobo nokusingqongileyo.

Njengoko imfuno yezinto zekhebula ezithembekileyo nezikhuselekileyo iqhubeka isanda, kulindeleke ukuba i-XLPE kunye ne-LSZH zidlale indima ebalulekileyo ekufezekiseni ezi mfuno.
