Njengoko iimfuno zokhuseleko lomlilo ziqhubeka zisanda kwiinkqubo zothutho lukaloliwe, amaziko edatha, izakhiwo eziphakamileyo, izibhedlele, kunye neeprojekthi zamandla avuselelekayo, iintambo zeLow Smoke Zero Halogen (LSZH) ziba lukhetho olukhethwayo kwizicelo ezininzi ezibalulekileyo. Kubavelisi beentambo, i-LSZH ingaphezulu nje kodidi lwemveliso—imele indlela yetekhnoloji yezinto ezahlukeneyo ngokusisiseko xa ithelekiswa neekhompawundi zePVC zemveli.
Yintoni i-LSZH Material?
I-LSZH (I-Low Smoke Zero Halogen), ekwaziwa ngokuba yi-Low Smoke Halogen Free (LSHF), ibhekisa kudidi lwezinto ezithintela ilangatye ezinobuhlobo nokusingqongileyo ezisetyenziselwa ukuthintela intambo kunye nokukhusela intambo. Kwishishini leentambo, ezi zinto zihlala zihlelwa njengeekhompawundi ze-HFFR (Halogen Free Flame Retardant).
Iikhompawundi ze-LSZH zihlala zisekelwe kwiiresini ze-polyolefin ezifana ne-polyethylene (PE) kunye ne-ethylene-vinyl acetate (EVA). Zenziwe ngezinto ezithintela ilangatye ezingenayo i-halogen, kubandakanya i-aluminium hydroxide (ATH) kunye ne-magnesium hydroxide (MDH), kunye nee-antioxidants, izinto zokuthambisa, kunye nezixhobo zokucubungula. Ngokungafaniyo neekhompawundi ze-PVC, izinto ze-LSZH azinazo i-chlorine, i-bromine, okanye ezinye izinto ze-halogen.
Xa kuthelekiswa neekhompawundi zekhebula zePVC eziqhelekileyo, izixhobo zeLSZH zinokugcina ubushushu obuhle bombane kunye neempawu zoomatshini ngelixa zinciphisa kakhulu ukuveliswa komsi kunye nokukhutshwa kwegesi erhabaxa ngexesha lokutsha. Ngenxa yoko, zisetyenziswa kakhulu kwiindawo zokusetyenziswa kweekhebula apho ukhuseleko lomlilo lubaluleke kakhulu.
Yintoni umahluko phakathi kweLSZH kunye nePVC?
I-Polyvinyl chloride (PVC) iseyeyona nto isetyenziswa kakhulu kwiintambo ngenxa yeteknoloji yayo yokucubungula evuthiweyo, ukusebenza kakuhle kweendleko, kunye nokusebenza okulinganayo. Isetyenziswa kakhulu ekwakheni iingcingo, iintambo zombane, kunye nokusetyenziswa kweentambo zoshishino.
Izinto ze-LSZH, ngokwahlukileyo, zisekelwe kwiinkqubo ze-polyolefin kwaye zifikelela ekuthinteleni ilangatye ngokusebenzisa izinto ezithintela ilangatye ezingaphiliyo endaweni yezongezo ezine-halogen. Umahluko omkhulu phakathi kwezi zimbini ubonakala xa kutsha.
I-PVC inokukhupha umsi omninzi kunye neegesi ezirhabaxa ezine-chlorine xa zitshiswa. Kwelinye icala, izixhobo ze-LSZH zivelisa umsi omncinci kakhulu kwaye azikhuphi buninzi beegesi ze-halogen acid. Oku kunceda ukugcina ukubonakala ngexesha lokufuduka kwaye kunciphisa umonakalo kwizixhobo zombane neze-elektroniki.
Ukongeza, izixhobo ze-LSZH zihambelana ngcono neemfuno zokhuseleko kunye nokusingqongileyo kwiiprojekthi zeziseko zophuhliso zanamhlanje, kubandakanya iinkqubo zothutho lukaloliwe, amaziko edatha, izikhululo zeenqwelo moya, izibhedlele kunye nezakhiwo zikawonke-wonke. I-PVC isabonelela ngeenzuzo ngokubhekiselele kwindleko kunye nokusebenza kakuhle kokucubungula, okwenza ukuba ifaneleke kwiintlobo ezininzi zezicelo zesiqhelo.
Ngokwembono yokumelana nobushushu, iikhompawundi ze-LSZH zinokwenziwa ukuze zihlangabezane nomlinganiselo wobushushu we-70°C, 90°C, 105°C, nangaphezulu, kuxhomekeke kwiimfuno zesicelo. Iikhompawundi zePVC zemveli zihlala zisetyenziswa kwiimveliso zekhebula ezilinganiselwe kwi-70°C okanye 90°C. Ngenxa yoko, izixhobo ze-LSZH ziyathandwa ngakumbi kwizicelo ezifuna ukhuseleko oluphuculweyo kunye nokusebenza kobushushu obuphezulu.
Yeyiphi iMigangatho ekufuneka ihlangabezane nezinto zeLSZH?
Izixhobo ze-LSZH zokwenyani mazihambelane nemigangatho eyaziwayo yoshishino kunye neemfuno zovavanyo.
Ngokusebenza okungenazo i-halogen, i-IEC 60754-1 kunye ne-IEC 60754-2 zihlala zibhekiselwa ekuvavanyeni ubungakanani beegesi ze-halogen acid ezikhutshwayo ngexesha lokutsha, kunye ne-acidity kunye ne-conductivity yeegesi zokutsha. I-IEC 60754-2 icacisa ukuba ixabiso le-pH yeegesi zokutsha kufuneka lingabi ngaphantsi kwe-4.3 kwaye i-conductivity mayingadluli kwi-10 μS/mm.
Ukuze kusebenze kancinci komsi, uthotho lwe-IEC 61034 lulinganisa uxinano lomsi ngovavanyo lokuhambisa ukukhanya.
Ukongeza, ukusebenza okubambezela ilangabi kudla ngokuvavanywa ngokwemigangatho ye-IEC 60332 kunye ne-GB/T 18380, ngelixa i-GB/T 19666 icacisa iimfuno zeentambo ezibambezela ilangabi kunye nezibambezela umlilo.
Kwiimarike zokuthumela ngaphandle kunye neeprojekthi zamazwe ngamazwe, izixhobo zekhebula nazo ziyimfuneko rhoqo ukuze kuthotyelwe imigaqo yokusingqongileyo efana neRoHS kunye neREACH.
Kutheni iiprojekthi ezininzi zikhetha iintambo ze-LSZH?
