I ka hoʻomau ʻana o nā koi palekana ahi e piʻi aʻe ana ma waena o nā ʻōnaehana kaʻaahi, nā kikowaena ʻikepili, nā hale kiʻekiʻe, nā haukapila, a me nā papahana ikehu hou, ke lilo nei nā kaula Low Smoke Zero Halogen (LSZH) i koho makemake ʻia no nā noi koʻikoʻi he nui. No nā mea hana kaula, ʻoi aku ka LSZH ma mua o kahi ʻano huahana wale nō—hōʻike ia i kahi ala ʻenehana mea ʻokoʻa loa i hoʻohālikelike ʻia me nā hui PVC kuʻuna.
He aha ka mea LSZH?
LSZH (Halogen Uwahi ʻOle Haʻahaʻa), i ʻike ʻia hoʻi ʻo Low Smoke Halogen Free (LSHF), pili i kahi papa o nā mea pale ahi aloha i ke kaiapuni i hoʻohana ʻia no ka insulation uwea a me ka sheathing. I loko o ka ʻoihana uwea, ua hoʻokaʻawale pinepine ʻia kēia mau mea e like me nā hui HFFR (Halogen Free Flame Retardant).
ʻO ka maʻamau, hoʻokumu ʻia nā hui LSZH ma nā resins polyolefin e like me ka polyethylene (PE) a me ka ethylene-vinyl acetate (EVA). Hoʻohui ʻia lākou me nā mea pale ahi halogen-free, me ka alumini hydroxide (ATH) a me ka magnesium hydroxide (MDH), me nā antioxidants, nā lubricants, a me nā mea kōkua hana. ʻAʻole e like me nā hui PVC, ʻaʻohe chlorine, bromine, a i ʻole nā mea halogen ʻē aʻe i loko o nā mea LSZH.
Ke hoʻohālikelike ʻia me nā hui kaula PVC maʻamau, hiki i nā mea LSZH ke mālama i ka insulation uila maikaʻi a me nā waiwai mechanical me ka hoʻemi nui ʻana i ka hana uahi a me nā hoʻokuʻu kinoea corrosive i ka wā e puhi ai. ʻO ka hopena, hoʻohana nui ʻia lākou i nā noi kaula kahi e noʻonoʻo nui ʻia ai ka palekana ahi.
He aha nā ʻokoʻa ma waena o LSZH a me PVC?
ʻO ka Polyvinyl chloride (PVC) kekahi o nā mea kaula i hoʻohana nui ʻia ma muli o kona ʻenehana hana paʻa, ka pono o ke kumukūʻai, a me ka hana kaulike holoʻokoʻa. Hoʻohana pinepine ʻia ia i ke kūkulu ʻana i nā uwea, nā kaula mana, a me nā noi kaula ʻoihana.
ʻO nā mea LSZH, ma ke ʻano ʻē aʻe, ua hoʻokumu ʻia ma nā ʻōnaehana polyolefin a hoʻokō i ka pale ʻana i ka lapalapa ma o nā mea pale lapalapa inorganic ma mua o nā mea hoʻohui halogen. ʻO ka ʻokoʻa koʻikoʻi ma waena o nā mea ʻelua e ʻike ʻia i ka wā o ke ahi.
Hiki i ka PVC ke hoʻokuʻu i ka nui o ka uahi a me nā kinoea ʻino i loaʻa i ka chlorine ke puhi ʻia. ʻO nā mea LSZH, ma ka ʻaoʻao ʻē aʻe, hana i ka uahi liʻiliʻi a ʻaʻole hoʻokuʻu i ka nui o nā kinoea halogen acid. Kōkua kēia i ka mālama ʻana i ka ʻike i ka wā e hoʻoneʻe ai a hōʻemi i ka pōʻino i nā lako uila a me nā mea uila.
Eia kekahi, ʻoi aku ka maikaʻi o nā mea LSZH me nā koi palekana a me ke kaiapuni o nā papahana ʻōnaehana hou, me nā ʻōnaehana kaʻaahi, nā kikowaena ʻikepili, nā kahua mokulele, nā haukapila, a me nā hale lehulehu. Hāʻawi mau ʻo PVC i nā pono ma ke ʻano o ke kumukūʻai a me ka pono o ka hana ʻana, e kūpono ai no nā noi maʻamau he nui.
Mai kahi kuanaʻike pale wela, hiki ke hoʻopili ʻia nā hui LSZH e hoʻokō i nā helu mahana o 70°C, 90°C, 105°C, a ʻoi aku paha, ma muli o nā koi o ka noi. Hoʻohana pinepine ʻia nā hui PVC kuʻuna i nā huahana kaula i helu ʻia ma 70°C a i ʻole 90°C. ʻO ka hopena, makemake nui ʻia nā mea LSZH i nā noi e koi ana i ka palekana i hoʻonui ʻia a me ka hana wela kiʻekiʻe.
He aha nā kūlana e pono ai nā mea LSZH e hoʻokō?
Pono nā mea LSZH maoli e kūlike me nā kūlana ʻoihana i ʻike ʻia a me nā koi hoʻāʻo.
No ka hana halogen-free, ua kuhikuhi pinepine ʻia ʻo IEC 60754-1 a me IEC 60754-2 e loiloi i ka nui o nā kinoea waikawa halogen i hoʻokuʻu ʻia i ka wā o ke kuni ʻana, a me ka acidity a me ka conductivity o nā kinoea kuni. Hoʻākāka ʻo IEC 60754-2 ʻaʻole pono e emi ka waiwai pH o nā kinoea kuni ma mua o 4.3 a ʻaʻole pono e ʻoi aku ka conductivity ma mua o 10 μS/mm.
No ka hana haʻahaʻa uahi, ana ka moʻo IEC 61034 i ka nui o ka uahi ma o ka hoʻāʻo ʻana i ka hoʻoili mālamalama.
Eia kekahi, loiloi pinepine ʻia ka hana pale ahi e like me nā kūlana IEC 60332 a me GB/T 18380, ʻoiai ʻo GB/T 19666 e kuhikuhi ana i nā koi no nā kaula pale ahi a me nā kaula pale ahi.
No nā mākeke hoʻokuʻu aku a me nā papahana honua, koi pinepine ʻia nā mea uwea e hoʻokō me nā lula kaiapuni e like me RoHS a me REACH.
No ke aha e koho ai nā papahana hou aku i nā kaula LSZH?
ʻO ka hoʻonui ʻia ʻana o ka hoʻohana ʻana i nā kaula LSZH e hoʻoulu ʻia e ka hoʻonui ʻana o nā koi no ka palekana ahi, ka palekana o ke kaiapuni, a me ka palekana waiwai.
ʻO nā pono nui:
Hoʻemi i ka hana ʻana o ka uahi i ka wā o nā hanana ahi, e hoʻomaikaʻi ana i ka ʻike no ka hoʻoneʻe ʻana a me ka pane ʻana i nā pilikia.
Hoʻemi ʻia ka hoʻokuʻu ʻana o nā kinoea ʻino, e kōkua ana i ka pale ʻana i nā ʻōnaehana kamaʻilio, nā ʻōnaehana mana, nā lako kikowaena ʻikepili, a me nā mea uila koʻikoʻi ʻē aʻe.
ʻO ka mālama ʻana i nā lula kaiapuni e paʻa mau ana a me nā kikoʻī o ka papahana.
Ke kūpono no nā noi palekana kiʻekiʻe e like me ke kaʻaahi kaʻaahi, nā kikowaena ʻikepili, nā kahua mokulele, nā haukapila, nā ʻōnaehana photovoltaic, nā kaʻa uila, a me nā hale lehulehu nui.
I ka manawa like, ua hoʻomaikaʻi nui ka holomua mau ʻana i ka ʻenehana mea i nā waiwai mechanical, ka hana thermal, nā ʻano hana, a me ka hilinaʻi lōʻihi o nā mea hoʻohuihui LSZH hou a me nā mea hoʻopaʻa, e hoʻonui hou ana i kā lākou laulā o nā noi.
Nā Hoʻonā Mea Uea LSZH HONUA HOʻOKAHI
Ma ke ʻano he mea hana mea uwea ʻoihana,HONUA HOʻOKAHIloea i ka noiʻi, hoʻomohala, hana ʻana, a me ke kākoʻo loea o nā mea kaula. ʻO kā mākou waihona huahana e pili ana i nā LSZH Sheathing Compounds, LSZH Insulation Compounds, HFFR Compounds, Cross-Linked Polyolefin (XLPO) Compounds, a me PVC Cable Compounds.
Hoʻohana nui ʻia kēia mau mea i nā kaula mana, nā kaula kamaʻilio, nā kaula kaʻaahi, nā kaula kikowaena ʻikepili, nā kaula photovoltaic, nā kaula kaʻa uila, a me nā noi kaula kūikawā ʻē aʻe.
Ma ka hoʻomau ʻana i ka hoʻomaikaʻi ʻana i ka hana o nā mea a me nā ʻano hana, ua kūpaʻa ʻo ONE WORLD i ka hāʻawi ʻana i nā mea hana uwea me nā hoʻonā mea hilinaʻi, a me ke kākoʻo loea e uhi ana i ke koho ʻana i nā mea, ka loiloi laʻana, a me ka hoʻokō ʻana i ka hana nui.
Hopena
I ka hoʻomau ʻana o ka piʻi ʻana o nā koi palekana ma waena o ke kaʻaahi kaʻaahi, nā kikowaena ʻikepili, ka ikehu hou, nā ʻōnaehana mālama ikehu, a me nā papahana ʻoihana aupuni, ke lilo nei nā mea LSZH i hoʻokahi o nā kuhikuhi hoʻomohala koʻikoʻi i loko o ka ʻoihana uwea.
Ke hoʻohālikelike ʻia me nā hui PVC kuʻuna, hāʻawi nā mea LSZH i nā pono koʻikoʻi ma ke ʻano o ka hoʻokuʻu ʻana i ka uahi haʻahaʻa, ka hana halogen-free, ka mālama ʻana i ke kaiapuni, a me ka pale ʻana i nā lako. ʻO ka hopena, ke lilo nei lākou i koho makemake ʻia no nā noi kaula palekana kiʻekiʻe.
Me nā kūlana ʻoihana e loli nei a me ke koi o ka mākeke e ulu nei, manaʻo ʻia e hoʻomau ka hoʻonui ʻia ʻana o nā mea kaula LSZH. E kūpaʻa mau ʻo ONE WORLD i ka hoʻomohala ʻana a me ka hana ʻana i nā mea kaula hana kiʻekiʻe, e hāʻawi ana i nā hoʻonā mea hilinaʻi a me ke kākoʻo loea ʻoihana i nā mea hana kaula ma ka honua holoʻokoʻa.
