Intuthu ephansi kanye nekhebula elingenayo i-halogen lisho ukuthi ungqimba lokufakwa kwentambo lwenziwe ngezinto ze-halogen.Ayiwakhiphi amagesi aqukethe i-halogen ngesikhathi sokusha futhi inentuthu encane egxilile.Ngakho-ke, sinakho endaweni yokucisha umlilo, ukuqapha, i-alamu kanye namanye amaphrojekthi abalulekile.Ngokuvamile abantu babhekisela kuntuthu ephansi kanye nekhebula elingenayo i-halogen njengekhebula elihambisana nemvelo, ngakho-ke ingabe intuthu ephansi nekhebula elingenayo i-halogen ngempela elihambisana nemvelo?Uma kungenjalo, uyini umehluko phakathi kwentambo ye-halogen yentuthu ephansi eyiziro kanye nekhebula elivumela imvelo?
Ikhebula le-halogen eliphansi lentuthu eliphansi liyikhebula elivumela imvelo ngempela?
Impendulo ithi cha, ikhebula le-halogen eliphansi lentuthu eliphansi alilona ikhebula elihambisana nemvelo.Izizathu yilezi:
(1) ikhebula elibizwa ngokuthi elinobungani bemvelo, libhekisela ekungabikho komthofu, i-cadmium, i-chromium ene-hexavalent, i-mercury nezinye izinsimbi ezisindayo, ayiqukethe izinto ezivimbela amalangabi e-brominated yizinhlangano zokuhlola ezaziwayo ze-SGS ekuhlolweni kokusebenza kwemvelo, ngokuhambisana ne-EU. I-Environmental Directive (RoSH) futhi ephakeme kunezimfuneko zayo zenkomba, ayikhiqizi amagesi e-halogen ayingozi, ayikhiqizi amagesi agqwalayo, inani elincane lapho isha, ayingcolisi intambo yomhlabathi nekhebula.Futhi ikhebula eliphansi le-halogen engenayo intuthu libhekisela ezintweni ezisetshenziselwa ungqimba lwezintambo ziyi-halogen impahla, esimweni sokusha alikhiphi igesi ye-halogen, ukugxila kwentuthu kuyintambo ephansi nekhebula.
(2)ikhebula lekhebula elingenantuthu ephansi le-halogen lenziwe ngentuthu ephansi uma lishisiwe, futhi lona ngokwalo aliqukethe i-halogen thermoplastic noma i-thermosetting, lapho inani le-halogen ≤ 50PPM, okuqukethwe kwe-hydrogen halide ekushisweni kwegesi engu-< 100PPM, ngemva kwalokho. ukushisa igesi ye-hydrogen halide encibilikisiwe emanzini inani le-PH lika-24.3 (i-acidity ebuthakathaka), umkhiqizo ushiswa esitsheni esivaliwe ngokukhanya kokukhanya izinga layo lokudlulisa ukukhanya lika-260%.
(3)ikhebula lokuvikela imvelo elilinganiselwe i-voltage engu-450/750V nangaphansi, izinga lokushisa eliphakeme kakhulu lesikhathi eside elivumelekile lekhondatha yekhebula akufanele lidlule ku-70, 90, 125 ℃ noma ngaphezulu;ikhebula elivuthayo ukuminyana kwentuthu ngokuhambisana nezindinganiso zikazwelonke, izinga lokudlulisa ukukhanya lika-≥ 260%;ukuhlolwa kokuqukethwe kwe-cable halogen acid ngokuhambisana namazinga kazwelonke, okungukuthi, inani le-PH ≥ 4.3, conductivity ≤ 10μus/mm;I-cable flame retardant Ukusebenza ngokuhambisana nezindinganiso zikazwelonke, inkomba yobuthi yekhebula ≤ 3.Ngamafuphi, okungenhla ukuthi ikhebula eliphansi le-halogen engenayo intuthu liqukethe yini ikhebula elihambisana nemvelo.Ngokwalokhu okungenhla singakwazi ukwazi ukuthi kuningi ukuxhumana nomehluko phakathi kwezintambo ezingenantuthu ephansi ye-halogen kanye nezintambo ezihambisana nemvelo.Intambo ephansi ye-halogen engenayo intuthu ayiyona ngempela intambo nekhebuli evumelana nemvelo, kodwa intambo nekhebuli evumelana nemvelo kufanele kube ikhebula eliphansi le-halogen engenayo intuthu.Ukuze kuthuthukiswe ukuphepha kwesekhethi ekhaya, i-Sunua Advanced Material incoma ukuthi usebenzise intuthu ephansi kanye nekhebula elicisha ilangabi elingena-halogen njengentambo kagesi yasekhaya.
