Nplaim Retardant Cables

Nplaim Retardant Cables

Flame-retardant cables yog tshwj xeeb tsim cov cables nrog cov ntaub ntawv thiab kev tsim kho kom zoo los tiv thaiv cov nplaim taws thaum muaj hluav taws kub. Cov kab hluav taws xob no txwv cov nplaim taws los ntawm kev nthuav tawm raws li txoj kab ntev thiab txo cov pa luam yeeb thiab cov pa phem thaum muaj hluav taws kub. Lawv feem ntau siv nyob rau hauv ib puag ncig uas muaj kev nyab xeeb hluav taws yog qhov tseem ceeb, xws li cov tsev pej xeem, kev thauj mus los, thiab cov chaw tsim khoom.

Hom Cov Khoom Siv Hauv Hluav Taws Xob Hluav Taws Xob Hluav Taws Xob

Cov txheej txheej polymer txheej sab nrauv thiab sab hauv yog qhov tseem ceeb hauv kev ntsuas hluav taws-retardant, tab sis tus qauv tsim ntawm cable tseem yog qhov tseem ceeb tshaj plaws. Ib lub tshuab hluav taws xob zoo, siv cov khoom siv hluav taws xob tsim hluav taws xob, tuaj yeem ua tiav cov khoom siv hluav taws xob xav tau.

Feem ntau siv cov polymers rau cov ntawv thov nplaim taws muaj xws liPVCthiabLSZH. Ob leeg yog tsim tshwj xeeb nrog cov nplaim hluav taws kub-retardant additives kom tau raws li qhov yuav tsum tau muaj kev nyab xeeb hluav taws.

Kev ntsuam xyuas tseem ceeb rau Cov Khoom Siv Hluav Taws Xob Hluav Taws Xob thiab Kev Txhim Kho Cable

Limiting Oxygen Index (LOI): Qhov kev ntsuas no ntsuas qhov tsawg kawg nkaus oxygen concentration nyob rau hauv ib qho kev sib xyaw ntawm cov pa thiab nitrogen uas yuav pab txhawb kev combustion ntawm cov ntaub ntawv, qhia raws li feem pua. Cov ntaub ntawv uas muaj LOI qis dua 21% raug cais raws li cov khoom siv hluav taws xob, thaum cov khoom uas muaj LOI ntau dua 21% raug cais raws li kev tua tus kheej. Qhov kev sim no muab kev nkag siab sai thiab yooj yim ntawm cov nplaim taws. Cov qauv siv tau yog ASTMD 2863 lossis ISO 4589

Cone Calorimeter: Cov cuab yeej no yog siv los kwv yees tus cwj pwm hluav taws hauv lub sijhawm tiag tiag thiab tuaj yeem txiav txim siab yam tsis xws li lub sijhawm hluav taws kub, qhov tso tawm cua sov, qhov poob ntau, tso pa tawm, thiab lwm yam khoom muaj feem cuam tshuam rau cov yam ntxwv hluav taws. Cov qauv siv tseem ceeb yog ASTM E1354 thiab ISO 5660, Cone calorimeter muab cov txiaj ntsig zoo dua.

Acid gas emission test (IEC 60754-1). Qhov kev ntsuas no ntsuas cov roj halogen acid cov ntsiab lus hauv cov cables, txiav txim siab tus nqi ntawm halogen emission thaum combustion.

Gas Corrositvity xeem (IEC 60754-2) Qhov kev ntsuas no ntsuas pH thiab conductivity ntawm cov khoom corrosive

Kev sim haus luam yeeb los yog 3m3 xeem (IEC 61034-2). Qhov kev ntsuam xyuas no ntsuas qhov ntom ntawm cov pa luam yeeb uas tsim los ntawm cov kab hluav taws kub hauv cov xwm txheej uas tau hais tseg. Qhov kev ntsuam xyuas yog ua nyob rau hauv lub chamber nrog qhov ntev ntawm 3 meters los ntawm 3 meters los ntawm 3 meters (li no lub npe 3m³ xeem) thiab yuav saib xyuas qhov txo nyob rau hauv lub teeb transmittance los ntawm cov pa luam yeeb tsim thaum lub sij hawm combustion.

Cov pa luam yeeb ntom ntom (SDR) (ASTMD 2843). Qhov kev ntsuam xyuas no ntsuas qhov ntom ntawm cov pa luam yeeb uas tsim los ntawm kev kub nyhiab lossis decomposition ntawm plastics nyob rau hauv kev tswj xyuas. Cov qauv ntsuas qhov ntev 25 mm x 25 mm x 6 mm
