Tsis tshua muaj pa luam yeeb thiab halogen-dawb cable txhais tau hais tias lub rwb thaiv tsev txheej ntawm lub cable yog ua los ntawm halogen tshuaj.Nws tsis tso halogen-muaj roj thaum lub sij hawm combustion thiab muaj cov pa luam yeeb tsawg.Yog li ntawd, peb muaj nws nyob rau hauv qhov chaw ntawm kev tua hluav taws, kev saib xyuas, tswb thiab lwm yam haujlwm tseem ceeb.Feem ntau cov neeg xa mus rau cov pa luam yeeb tsawg thiab halogen-dawb cable raws li ib puag ncig tus phooj ywg cable, yog li tsis muaj pa luam yeeb thiab halogen-free cable tiag tiag ib puag ncig tus phooj ywg cable?Yog tias tsis yog, qhov sib txawv ntawm cov pa luam yeeb tsawg xoom halogen cable thiab ib puag ncig tus phooj ywg cable yog dab tsi?
Tsawg pa luam yeeb xoom halogen cable puas yog ib puag ncig tus phooj ywg cable?
Cov lus teb yog tsis muaj, tsis muaj pa luam yeeb xoom halogen cable tsis yog ib puag ncig tus phooj ywg cable.Cov laj thawj yog:
(1) lub npe hu ua ib puag ncig tus phooj ywg cable, hais txog qhov tsis muaj cov hlau lead, cadmium, hexavalent chromium, mercury thiab lwm yam hlau hnyav, tsis muaj cov nplaim hluav taws kub hnyiab los ntawm SGS lees paub cov koom haum soj ntsuam ntawm ib puag ncig kev ntsuas, raws li EU Environmental Directive (RoSH) thiab siab tshaj nws qhov ntsuas qhov yuav tsum tau ua, tsis tsim cov pa phem halogen, tsis tsim cov roj corrosive, tsawg dua thaum hlawv, tsis ua qias neeg hauv av xaim thiab cable.Thiab tsis tshua muaj pa halogen-dawb cable hais txog cable rwb thaiv tsev txheej khoom yog halogen khoom, nyob rau hauv cov ntaub ntawv ntawm combustion tsis tso halogen roj, pa luam yeeb concentration yog tsawg hlau thiab cable.
(2) Cov pa hluav taws xob qis qis halogen-free cable sheath yog ua los ntawm cov pa luam yeeb tsawg thaum cua sov, thiab nws tus kheej tsis muaj halogen thermoplastic los yog thermosetting muaj pes tsawg leeg, qhov twg tus nqi halogen ≤ 50PPM, hydrogen halide cov ntsiab lus nyob rau hauv combustion ntawm cov pa <100PPM, tom qab hlawv cov roj hydrogen halide yaj hauv dej PH tus nqi ntawm 24.3 (tsis muaj acidity), cov khoom raug hlawv hauv lub thawv kaw los ntawm lub teeb ntawm lub teeb nws lub teeb kis tau tus nqi ntawm 260%.
(3) Kev tiv thaiv ib puag ncig cable ntsuas qhov hluav taws xob ntawm 450 / 750V thiab hauv qab no, qhov siab tshaj plaws rau lub sijhawm ntev ua haujlwm kub ntawm tus neeg xyuas pib yuav tsum tsis pub tshaj 70, 90, 125 ℃ lossis siab dua;cable hlawv cov pa luam yeeb ceev raws li lub teb chaws cov qauv, lub teeb kis tus nqi ntawm ≥ 260%;cable halogen acid cov ntsiab lus kuaj raws li lub teb chaws tus qauv, uas yog, PH nqi ≥ 4.3, conductivity ≤ 10μus / mm;cable nplaim taws retardant Kev ua tau zoo nyob rau hauv txoj kab nrog lub teb chaws tus qauv, lub cable lub toxicity Performance index ≤ 3.Nyob rau hauv luv luv, cov saum toj no yog seb tsis muaj pa taws halogen-free cable yog ib puag ncig tus phooj ywg cable ntsig txog cov ntsiab lus.Los ntawm cov saum toj no peb tuaj yeem paub tias muaj ntau qhov kev sib txuas thiab qhov sib txawv ntawm cov pa hluav taws xob tsis muaj halogen cables thiab cov kab hluav taws xob ib puag ncig.Tsis tshua muaj pa halogen-free cable tsis tas ib puag ncig tus phooj ywg hlau thiab cable, tab sis ib puag ncig tus phooj ywg xaim thiab cable yuav tsum yog cov pa luam yeeb tsis muaj halogen cable.Txhawm rau txhim kho kev nyab xeeb ntawm lub voj voog hauv tsev, Sunua Advanced Material xav kom koj siv cov pa taws tsawg thiab tsis muaj halogen-dawb nplaim hluav taws xob raws li koj lub tsev hluav taws xob xaim.
