Cable kev nyab xeeb yog ib qho kev txhawj xeeb tseem ceeb thoob plaws kev lag luam, tshwj xeeb tshaj yog thaum nws los txog rau cov pa luam yeeb tsawg thiab halogen-dawb fais fab cable cim. Low Smoke Halogen Free (LSHF) cables yog tsim los txo qis cov pa luam yeeb thiab cov pa phem thaum muaj hluav taws, ua rau lawv muaj kev nyab xeeb dua rau cov chaw kaw lossis cov neeg nyob ze. Kev txheeb xyuas cov kab hluav taws xob no yog qhov tseem ceeb los ua kom muaj kev nyab xeeb thiab ua raws li koj qhov kev teeb tsa hluav taws xob.Yog li yuav ua li cas txheeb xyuas cov hluav taws xob tsis muaj pa taws halogen tsis muaj hluav taws xob? Tom ntej no, peb yuav coj koj los nkag siab txog kev txheeb xyuas cov pa luam yeeb halogen-dawb nplaim hluav taws xob retardant hlau.
1.Insulation nto hlawv txoj kev. Cov txheej rwb thaiv tsev yuav tsum tau ironed yam tsis muaj kev nyuaj siab pom tseeb, thiab yog tias muaj kev ntxhov siab loj, nws qhia tau tias cov khoom siv lossis cov txheej txheem siv nyob rau hauv cov txheej txheem rwb thaiv tsev tsis raug. Los yog barbecue nrog ib lub teeb, nyob rau hauv ib txwm muaj teeb meem yuav tsum tsis yooj yim rau ignite, lub rwb thaiv tsev txheej ntawm lub cable yog tseem ua tiav tom qab ib tug ntev lub sij hawm ntawm burning, tsis muaj pa taws thiab irritating tsw, thiab txoj kab uas hla tau nce. Yog tias nws yooj yim rau ignite, koj tuaj yeem paub tseeb tias cov txheej txheem rwb thaiv tsev ntawm lub cable tsis yog ua los ntawm cov khoom siv hluav taws xob tsawg halogen-dawb (feem ntau yuav yog polyethylene lossis crosslinked polyethylene). Yog tias muaj cov pa luam yeeb loj, nws txhais tau hais tias cov txheej txheej rwb thaiv tsev siv cov khoom siv halogenated. Yog hais tias tom qab ib tug ntev lub sij hawm ntawm combustion, lub rwb thaiv tsev nto yog tiag los, thiab txoj kab uas hla yog tsis ho nce, nws qhia tau hais tias tsis muaj tsim nyog irradiation crosslinking txheej txheem kev kho mob.
2.Density piv txoj kev.Raws li qhov ntom ntawm cov dej, cov khoom yas yog muab tso rau hauv dej. Yog hais tias nws tog, cov yas yog denser dua dej, thiab yog hais tias nws ntab, cov yas yog denser dua dej. Txoj kev no tuaj yeem siv ua ke nrog lwm txoj hauv kev.
3.Kev txheeb xyuas cov pa luam yeeb tsawg halogen-dawb nplaim retardant kab los ntawm cov dej kub soaking. Cov tub ntxhais hlau los yog cable yog tsau rau hauv dej kub ntawm 90 ℃, feem ntau, cov rwb thaiv tsev tiv thaiv yuav tsis poob sai, thiab nyob twj ywm siab tshaj 0.1MΩ / Km. Yog tias cov rwb thaiv tsev tiv thaiv poob qis dua 0.009MΩ / Km, nws qhia tau tias tsis tau siv cov txheej txheem irradiation crosslinking tsim nyog.
