I-LSZH yindlela emfutshane ye-Low Smoke Zero Halogen.Ezi ntambo zakhiwe ngemathiriyeli yebhatyi ngaphandle kwemathiriyeli yehalogenic efana neklorin kunye nefluorine njengoko le michiza inendalo eyityhefu xa itshiswa.
Izibonelelo okanye iingenelo zentambo ye-LSZH
Okulandelayo zizibonelelo okanye iingenelo zentambo ye-LSZH:
➨Zisetyenziswa apho abantu bakufutshane kakhulu neendibano zentambo apho bangafumani mvula yaneleyo yokuphefumla xa kutsha okanye kukho iindawo zokungena umoya ezingekho mgangathweni.
➨Abiza kakhulu.
➨Zisetyenziswa kwiinkqubo zikaloliwe apho iingcingo zemiqondiso yamandla ombane aphezulu zisetyenziswa kwiitonela ezingaphantsi komhlaba.Oku kuya kunciphisa amathuba okufumba kweegesi eziyityhefu xa iintambo zitshiswa.
➨Zakhiwa kusetyenziswa iikhompawundi ze-thermoplastic ezikhupha umsi omncinci ngaphandle kwehalogen.
➨Azivelisi gesi eyingozi xa zidibana nemithombo yobushushu obuphezulu.
➨LSZH ibhatyi yekheyibhile inceda ekukhuseleni abantu xa kukho umlilo, umsi kunye negesi eyingozi ngenxa yokutsha kweentambo.
Ukungaphumeleli okanye ukungalungi kwentambo ye-LSZH
Oku kulandelayo zizithintelo okanye izinto ezingalunganga zentambo ye-LSZH:
Ibhatyi yekhebula ye-➨LSZH isebenzisa i-% ephezulu yezinto zokuzalisa ukuze inike umsi ophantsi kunye ne-zero halogen.Oku kwenza ibhatyi ingaphantsi kweekhemikhali / ukuxhathisa amanzi xa ithelekiswa ne-non-LSZH i-cable counterpart.
➨Ijacket ye-LSZH ikhebula ikhebula ngexesha lofakelo.Yiyo loo nto kufuneka izithambiso ezikhethekileyo ukunqanda umonakalo.
➨Inika ukuguquguquka okulinganiselweyo kwaye ayifanelekanga kwirobhothi.
Ukuba ukukhuselwa kwezixhobo okanye abantu kuyimfuneko yoyilo, qwalasela i-low-smoke zero-halogen (LSZH) iintambo zebhatyi.Zikhupha imisi eyityhefu embalwa kuneebhatyi zentambo ezisekwe kwiPVC.Ngokuqhelekileyo, ikhebula le-LSZH lisetyenziswa kwiindawo ezivaliweyo ezifana nokusebenza kwemigodi apho umoya uxhalabileyo.
Uthini umahluko phakathi kwentambo ye-LSZH kunye neentambo eziqhelekileyo?
Umsebenzi kunye nobuchule beparamitha ye-LSZH intambo yefiber optic ifana nje neentambo eziqhelekileyo zefiber optic, kunye nesakhiwo sangaphakathi siyafana, umahluko osisiseko ziibhatyi.Iibhatyi ze-LSZH ze-fiber optic ziyakwazi ukumelana nomlilo ngakumbi xa zithelekiswa neentambo eziqhelekileyo ze-PVC ezinebhatyi, nokuba zibanjwe emlilweni, iintambo ze-LSZH ezitshisiweyo zibonelela ngomsi ophantsi kwaye azikho izinto ze-halogen, eli nqaku alikhuseli nje indawo esingqongileyo kodwa umsi ophantsi xa lifumene. kutshiswe kubalulekile ebantwini nakwizibonelelo kwindawo etshisiweyo.
Ijacket ye-LSZH yenziwe ngezinto ezikhethekileyo kakhulu ezingenayo i-halogenated kunye ne-flame retardant.I-LSZH i-cable jacketing yenziwe nge-thermoplastic okanye i-thermoset compounds ekhupha umsi omncinci kwaye akukho halogen xa ibonakaliswe kwimithombo ephezulu yobushushu.Intambo ye-LSZH inciphisa ubungakanani begesi eyityhefu enobungozi kunye ne-corrosive ekhutshwa ngexesha lokutsha.Olu hlobo lwemathiriyeli luqhele ukusetyenziswa kwiindawo ezingangeni moya kakuhle ezifana nenqwelomoya okanye iimoto zikaloliwe.Iibhatyi ze-LSZH zikwakhuselekile kuneebhatyi zentambo ezilinganiswe ngePlenum ezinokutsha okuphantsi kodwa zisakhupha umsi oyityhefu kunye ne-caustic xa zitshisiwe.
Umsi ophantsi we-zero halogen uthandwa kakhulu kwaye, kwezinye iimeko, imfuneko apho ukhuseleko lwabantu kunye nezixhobo kwigesi enetyhefu kunye ne-corrosion ibaluleke kakhulu.Olu hlobo lwentambo luhlala lubandakanyeka emlilweni umsi omncinci kakhulu oveliswayo okwenza le ntambo ibe lolona khetho lubalaseleyo kwiindawo ezivalelweyo ezinjengeenqanawa, iinqanawa ezintywilayo, iinqanawa ezintywilayo, iinqwelomoya, amagumbi aphezulu eseva kunye namaziko womnatha.
Yintoni umahluko phakathi kwePVC kunye neentambo zeLSZH?
Ngokomzimba, i-PVC kunye ne-LSZH zihluke kakhulu.Iipatchcords zePVC zithambile kakhulu;I-LSZH patchcords yomelele ngakumbi ngenxa yokuba iqulethe ikhompawundi ebuyisela idangatye, kwaye ithandeka ngakumbi ngobuhle.
Intambo yePVC (eyenziwe nge-polyvinyl chloride) inebhatyi ekhupha umsi onzima omnyama, i-hydrochloric acid, kunye nezinye iigesi eziyityhefu xa isitsha.Intambo yoMsi oPhantsi i-Zero Halogen (LSZH) inebhatyi ekwaziyo ukumelana nedangatye engakhuphi umsi oyityhefu nokuba iyatsha.
I-LSZH ibiza kakhulu kwaye ayiguquki kancinci
Iintambo ze-LSZH zihlala zibiza ngaphezu kwentambo ye-PVC elinganayo, kwaye iintlobo ezithile aziguquki kancinci.Intambo ye-LSZH inezithintelo ezithile.Ngokwemigangatho ye-CENELEC EN50167, 50168, 50169, iikheyibhile ezifihliweyo kufuneka zingabikho i-halogen.Nangona kunjalo, akukho mgaqo ufanayo osebenzayo kwiintambo ezingakhuselwanga.
