Ukusetshenziswa Kwezisetshenziswa Zekhebula Le-Halogen Engenantuthu Ephansi Kanye Nezisetshenziswa Zekhebula Le-Cross-linked Polyethylene (XLPE)

Eminyakeni yakamuva, isidingo sekhebula le-low-smoke halogen-free (LSZH) senyuke kakhulu ngenxa yokuphepha kanye nezinzuzo zemvelo. Enye yezinto ezibalulekile ezisetshenziswa kulezi zintambo yi-crosslinked polyethylene (XLPE).

1. YiniI-Cross-linked Polyethylene (XLPE)?

I-polyethylene exhunywe esiphambanweni, evame ukufushaniswa i-XLPE, iyimpahla ye-polyethylene eshintshiwe ngokungezwa kwe-crosslinker. Le nqubo yokuxhumanisa ithuthukisa izici ezishisayo, zemishini kanye namakhemikhali ezinto ezibonakalayo, okwenza kube ekahle ekusetshenzisweni okuhlukahlukene. I-XLPE isetshenziswa kakhulu ezinhlelweni zamapayipi esevisi yokwakha, izinhlelo zokufudumeza ezikhazimulayo zama-hydraulic kanye nokupholisa, amapayipi amanzi asekhaya kanye nokufakwa kwekhebula lamandla kagesi aphezulu.

2. Izinzuzo ze-XLPE insulation

Ukufakwa kwe-XLPE kunikeza izinzuzo ezimbalwa kuzinto zendabuko ezifana ne-polyvinyl chloride (PVC).
Lezi zinzuzo zihlanganisa:
Ukuzinza kwe-thermal: I-XLPE ingakwazi ukumelana namazinga okushisa aphezulu ngaphandle kokuguqulwa futhi ngakho-ke ifanele izicelo zokucindezela okuphezulu.
Ukumelana namakhemikhali: Isakhiwo esixhumene sinokumelana okuhle kakhulu kwamakhemikhali, siqinisekisa ukuqina ezindaweni ezinokhahlo.
Amandla omshini: I-XLPE inezici ezinhle kakhulu zemishini, okuhlanganisa ukumelana nokugqoka kanye nokuqhekeka kwengcindezi.
Ngakho-ke, izinto zekhebula le-XLPE zivame ukusetshenziswa ekuxhumekeni kwangaphakathi kagesi, izintambo zezimoto, izibani zokukhanyisa, izintambo ezinamandla kagesi ngaphakathi kwezimoto ezintsha zamandla, imigqa yokulawula isignali ephansi, izintambo zesitimela, izintambo zesitimela, izintambo zokuvikela imvelo, izintambo zasolwandle, izintambo ze-nuclear. izintambo zokubeka amandla, izintambo ze-TV zamandla kagesi aphezulu, izintambo ze-X-RAY ezinamandla kagesi kanye namakhebuli adlulisa amandla.
Polyethylene crosslinking ubuchwepheshe

Ukuxhumanisa i-polyethylene kungafinyelelwa ngezindlela ezihlukahlukene, kuhlanganise nemisebe, i-peroxide kanye ne-silane crosslinking. Indlela ngayinye inezinzuzo zayo futhi ingakhethwa ngokuya ngezidingo ezithile zohlelo lokusebenza. Izinga le-crosslinking lithinta kakhulu izakhiwo zezinto. Ukuphakama kwe-crosslinking density, kuba ngcono izici ezishisayo nezomshini.

3. ZiyiniI-low-smoke halogen-free (LSZH)izinto zokwakha?

Izinto ezingenantuthu ephansi ye-halogen (LSZH) ziklanywe ngendlela yokuthi izintambo ezivezwe emlilweni zikhulule inani elincane lentuthu lapho zivutha futhi zingakhiqizi intuthu enobuthi ye-halogen. Lokhu kubenza bafaneleke kakhulu ukusetshenziswa Ezikhaleni ezivalekile kanye nezindawo ezingenamoya omubi, njengamahubhu, amanethiwekhi kaloliwe angaphansi komhlaba kanye nezakhiwo zomphakathi. Izintambo ze-LSZH zenziwe ngezinhlanganisela ze-thermoplastic noma ze-thermoset futhi zikhiqiza amazinga aphansi kakhulu entuthu nentuthu enobuthi, okuqinisekisa ukubonakala okungcono kanye nezingozi ezinciphisa impilo ngesikhathi somlilo.

4. Isicelo sezinto zekhebula le-LSZH

Izinto zekhebula le-LSZH zisetshenziswa ezinhlobonhlobo zezicelo lapho ukukhathazeka kokuphepha nemvelo kubaluleke kakhulu.
Ezinye izinhlelo zokusebenza ezibalulekile zifaka:
Izinto zekhebula zezakhiwo zomphakathi: Izintambo ze-LSZH zivame ukusetshenziswa ezakhiweni zomphakathi njengezikhumulo zezindiza, iziteshi zesitimela nezibhedlela ukuze kuqinisekiswe ukuphepha ngesikhathi somlilo.
Amakhebuli ezokuthutha: Lawa makhebuli asetshenziswa ezimotweni, ezindizeni, ezimotweni zezitimela nasemikhunjini ukuze kuncishiswe ingozi yentuthu enobuthi uma kuba nomlilo.
Izintambo zenethiwekhi yomhubhe kanye nezitimela ezingaphansi komhlaba: Izintambo ze-LSZH zinentuthu ephansi nezici ezingenayo i-halogen, okuzenza zilungele ukusetshenziswa emhubheni nakumanethiwekhi kaloliwe angaphansi komhlaba.
Izintambo ze-Class B1: Izinto ze-LSZH zisetshenziswa ezintamboni ze-Class B1, eziklanyelwe ukuhlangabezana nezindinganiso eziqinile zokuphepha komlilo futhi zisetshenziswa ezakhiweni ezinde nakwezinye izingqalasizinda ezibalulekile.

Intuthuko yakamuva kubuchwepheshe be-XLPE kanye ne-LSZH igxile ekuthuthukiseni ukusebenza kwezinto kanye nokwandisa izinhlelo zayo zokusebenza. Izinto ezintsha zihlanganisa ukuthuthukiswa kwe-high-density cross-linked polyethylene (XLHDPE), ethuthukise ukumelana nokushisa nokuqina.

Izinto eziguquguqukayo neziqinile, ezixhumene kakhulu ne-polyethylene (XLPE) nezinto zekhebula ze-zero-halogen (LSZH) ezinomusi ophansi zisetshenziswa kakhulu ezimbonini ezahlukahlukene ngenxa yezakhiwo zazo ezinhle kakhulu ezishisayo, zamakhemikhali nezomshini. Izicelo zabo ziyaqhubeka nokukhula ngokuthuthuka okuqhubekayo kobuchwepheshe kanye nesidingo esikhulayo sezinto eziphephile nezingangeni imvelo.

Njengoba isidingo sezinto zamakhebula ezithembekile neziphephile siqhubeka nokwanda, i-XLPE ne-LSZH kulindeleke ukuthi ibambe iqhaza elibalulekile ekuhlangabezaneni nalezi zidingo.
