Kugwiritsa Ntchito Zida Zopanda Utsi Zopanda Halogen Zopanda Utsi Ndi Zingwe Za Polyethylene (XLPE) Zolumikizidwa

M'zaka zaposachedwa, kufunikira kwa zida za chingwe cha halogen-free halogen-free (LSZH) zotsika utsi kwakula chifukwa cha chitetezo komanso ubwino wa chilengedwe. Chimodzi mwazinthu zofunikira zomwe zimagwiritsidwa ntchito pazingwezi ndi crosslinked polyethylene (XLPE).

1. Ndi chiyaniPolyethylene yolumikizidwa (XLPE)?

Polyethylene yolumikizidwa ndi mtanda, yomwe nthawi zambiri imafupikitsidwa XLPE, ndi zinthu za polyethylene zomwe zasinthidwa ndi kuwonjezera kwa crosslinker. Njira yolumikizirana iyi imawonjezera kutentha, makina ndi mankhwala azinthuzo, zomwe zimapangitsa kuti zikhale zabwino pakugwiritsa ntchito zosiyanasiyana. XLPE imagwiritsidwa ntchito kwambiri pomanga mapaipi opangira ntchito, ma hydraulic radiant heat and cooling system, mapaipi amadzi am'nyumba komanso kutsekereza chingwe champhamvu kwambiri.

2. Ubwino wa kusungunula kwa XLPE

Kupaka kwa XLPE kumapereka maubwino angapo kuposa zida zachikhalidwe monga polyvinyl chloride (PVC).
Ubwinowu ndi:
Kukhazikika kwamafuta: XLPE imatha kupirira kutentha kwambiri popanda kupunduka ndipo ndiyoyenera kugwiritsa ntchito kupanikizika kwambiri.
Kukana kwa Chemical: Mapangidwe ophatikizika amakhala ndi kukana kwamphamvu kwamankhwala, kuwonetsetsa kulimba m'malo ovuta.
Mphamvu zamakina: XLPE ili ndi zida zabwino zamakina, kuphatikiza kukana kuvala komanso kusweka kwa nkhawa.
Chifukwa chake, zida zamagetsi za XLPE zimagwiritsidwa ntchito polumikizira mkati mwamagetsi, zowongolera zamagalimoto, zowongolera zowunikira, mawaya okwera kwambiri mkati mwa magalimoto atsopano amagetsi, mizere yowongolera ma siginecha otsika, mawaya oyenda, zingwe zapansi panthaka, zingwe zoteteza zachilengedwe, zingwe zapanyanja, zida zanyukiliya. zingwe zoyakira mphamvu, zingwe zapa TV zothamanga kwambiri, zingwe za X-RAY zothamanga kwambiri komanso zingwe zotumizira mphamvu.
Polyethylene crosslinking luso

Crosslinking wa polyethylene chingapezeke mwa njira zosiyanasiyana, kuphatikizapo poizoniyu, peroxide ndi silane crosslinking. Njira iliyonse ili ndi ubwino wake ndipo ikhoza kusankhidwa malinga ndi zofunikira zomwe zimagwiritsidwa ntchito. Mlingo wa crosslinking kwambiri zimakhudza katundu wa zinthu. The apamwamba crosslinking kachulukidwe, bwino matenthedwe ndi makina katundu.

3. Ndi chiyanilow-smoke halogen-free (LSZH)zipangizo?

Zida zopanda utsi wa halogen (LSZH) zimapangidwira kuti zingwe zomwe zimayaka moto zitulutse utsi wocheperako zikayaka komanso kuti zisatulutse utsi wakupha wa halogen. Izi zimawapangitsa kukhala oyenera kugwiritsidwa ntchito m'malo otsekeka komanso m'malo opanda mpweya wabwino, monga ngalande, njanji zapansi panthaka ndi nyumba zapagulu. Zingwe za LSZH zimapangidwa ndi mankhwala a thermoplastic kapena thermoset ndipo zimatulutsa utsi wochepa kwambiri ndi utsi wapoizoni, kuwonetsetsa kuti ziwonekere bwino komanso kuchepetsa kuopsa kwa thanzi pakayaka moto.

4. LSZH chingwe zinthu ntchito

Zipangizo zamagetsi za LSZH zimagwiritsidwa ntchito m'njira zosiyanasiyana pomwe nkhawa zachitetezo ndi chilengedwe ndizofunikira.
Zina mwazofunikira ndi izi:
Zipangizo zama chingwe zomanga nyumba za anthu: Zingwe za LSZH zimagwiritsidwa ntchito kwambiri m'nyumba za anthu monga ma eyapoti, masitima apamtunda ndi zipatala kuti zitsimikizire chitetezo pakayaka moto.
Zingwe zonyamulira: Zingwezi zimagwiritsidwa ntchito m’magalimoto, ndege, m’magalimoto apamtunda ndi m’sitima pofuna kuchepetsa kuopsa kwa utsi wapoizoni ukayaka moto.
Zingwe za njanji zapansi panthaka ndi zapansi panthaka: Zingwe za LSZH zili ndi utsi wochepa komanso mawonekedwe opanda halogen, zomwe zimawapangitsa kukhala abwino kugwiritsa ntchito mumphangayo ndi maukonde apansi panthaka.
Zingwe za Class B1: Zipangizo za LSZH zimagwiritsidwa ntchito mu zingwe za Class B1, zomwe zimapangidwira kuti zigwirizane ndi miyezo yolimba ya chitetezo cha moto ndipo zimagwiritsidwa ntchito m'nyumba zazitali ndi zipangizo zina zofunika kwambiri.

Kupita patsogolo kwaposachedwa kwaukadaulo wa XLPE ndi LSZH kumayang'ana kwambiri kuwongolera magwiridwe antchito ndi kukulitsa ntchito zake. Zatsopano zikuphatikizapo kupanga polyethylene (XLHDPE) ya high-density cross-linked polyethylene, yomwe imapangitsa kuti kutentha kukhale kolimba komanso kukhazikika.

Zipangizo zosunthika komanso zokhazikika, zolumikizidwa ndi polyethylene (XLPE) ndi chingwe chotsika cha zero-halogen (LSZH) zimagwiritsidwa ntchito kwambiri m'mafakitale osiyanasiyana chifukwa cha kutentha kwawo, mankhwala komanso makina. Ntchito zawo zikupitilira kukula ndikupita patsogolo kwaukadaulo komanso kufunikira kwazinthu zotetezeka komanso zoteteza zachilengedwe.

Pomwe kufunikira kwa zida zodalirika komanso zotetezeka kukukulirakulira, XLPE ndi LSZH akuyembekezeka kutenga gawo lalikulu pakukwaniritsa izi.
