Utsi wochepa komanso chingwe chopanda halogen chimatanthawuza kuti chingwe chosungunula cha chingwecho chimapangidwa ndi zinthu za halogen.Simatulutsa mpweya wokhala ndi halogen panthawi yoyaka ndipo imakhala ndi utsi wochepa.Chifukwa chake, tili nazo m'malo ozimitsa moto, kuyang'anira, ma alarm ndi ntchito zina zofunika.Nthawi zambiri anthu amatchula utsi wochepa ndi chingwe chopanda halogen ngati chingwe chogwirizana ndi chilengedwe, ndiye kodi utsi wochepa ndi chingwe chopanda halogen ndi chingwe chogwirizana ndi chilengedwe?Ngati sichoncho, pali kusiyana kotani pakati pa chingwe chotsika cha zero halogen ndi chingwe chogwirizana ndi chilengedwe?
Chingwe chotsika cha zero halogen ndi chingwe chogwirizana ndi chilengedwe?
Yankho ndi ayi, chingwe chotsika cha zero halogen si chingwe chogwirizana ndi chilengedwe.Zifukwa zake ndi:
(1) chingwe chotchedwa chilengedwe chochezeka, chimatanthawuza kusakhalapo kwa lead, cadmium, hexavalent chromium, mercury ndi zitsulo zina zolemera, mulibe brominated flame retardants ndi mabungwe oyesa odziwika a SGS pa kuyezetsa ntchito zachilengedwe, mogwirizana ndi EU. Environmental Directive (RoSH) komanso yapamwamba kuposa momwe imafunikira index, sichitulutsa mpweya woipa wa halogen, sichitulutsa mpweya wowononga, wocheperako poyaka, sichiipitsa waya ndi chingwe.Ndipo otsika utsi halogen wopanda chingwe amatanthauza chingwe kutchinjiriza zakuthupi wosanjikiza ndi halogen zakuthupi, mu nkhani ya kuyaka samasula mpweya halogen, utsi ndende ndi otsika waya ndi chingwe.
(2) chingwe chochepa cha halogen chopanda utsi chimapangidwa ndi utsi wochepa chikatenthedwa, ndipo sichikhala ndi halogen thermoplastic kapena thermosetting, pamene mtengo wa halogen ≤ 50PPM, hydrogen halide zili mu kuyaka kwa gasi <100PPM, pambuyo pake kuyatsa mpweya wa haidrojeni halide wosungunuka m'madzi PH mtengo wa 24.3 (acidity yofooka), mankhwalawa amawotchedwa mu chidebe chotsekedwa kudzera mumtengo wa kuwala kwake kufalikira kwa 260%.
(3) chilengedwe chitetezo chingwe oveteredwa voteji 450/750V ndi pansipa, apamwamba kwambiri ovomerezeka ntchito kutentha kwa nthawi yaitali wa kondakitala chingwe sayenera upambana 70, 90, 125 ℃ kapena apamwamba;chingwe choyaka utsi kachulukidwe mogwirizana ndi mfundo dziko, kuwala kufala mlingo wa ≥ 260%;chingwe halogen asidi okhutira mayeso mogwirizana ndi mfundo dziko, ndiye PH mtengo ≥ 4.3, madutsidwe ≤ 10μus/mm;cable flame retardant Magwiridwe mogwirizana ndi mfundo za dziko, chingwe cha kawopsedwe index ≤ 3.Mwachidule, pamwamba ngati otsika utsi halogen-free chingwe ndi chilengedwe wochezeka chingwe zokhudzana zili.Kuchokera pamwambapa titha kudziwa kuti pali kulumikizana ndi kusiyana kwakukulu pakati pa zingwe zopanda utsi za halogen zopanda utsi ndi zingwe zoteteza chilengedwe.Chingwe chotsika cha halogen chopanda utsi sichiyenera kukhala ndi waya ndi chingwe chogwirizana ndi chilengedwe, koma mawaya ogwirizana ndi chilengedwe ndi chingwe chiyenera kukhala chingwe chotsika cha halogen wopanda utsi.Pofuna kupititsa patsogolo chitetezo cha dera kunyumba, Sunua Advanced Material imalimbikitsa kuti mugwiritse ntchito utsi wochepa komanso chingwe chotchinga moto cha halogen ngati waya yanu yamagetsi.
