Qhov Tseem Ceeb Ntawm R & D Thiab Daim Ntawv Thov Cov Pa Luv Luv, Tsaug Toxicity (Halogen) Nplaim Retardant Cable Rau Qhov Ncauj Mines
May 08, 2018

Xyoo 20 xyoo dhau los, cov hlua siv hauv cov mines me tau ua dua tshiab los ntawm cov uas tsis yog nplaim hluav taws rau cov hluav taws-tshwjxeeb, tshwj xeeb tshaj yog cov kev xeem thiab kev txiavtxim siab rau cov nplaim taws ntawm cov nplaim taws hluav taws xob (MT 386- Xyoo 1995, MT 386-2011 Txij li thaum nws tshaj tawm thiab kev siv, qhov nplaim hluav taws kub ntawm cov nplaim hluav taws kub tau tswj tau thiab zoo dua.


Txawm li cas los xij, hluav taws xob hluav taws xob (hluav taws xob tsawg dua qub) rau cov pob txha (feem ntau siv cov tshuaj uas muaj cov tshuaj polymers los ua cov ntaub ntim khoom) ib zaug hlawv los ntawm tshav kub, cov pa luam yeeb uas tau tso los ntawm kev sib dhos yog loj heev. Txawm hais tias lub teeb ntsuas ntawm IEC 61034 los sis GB / T 17651-1-1998 tsawg tshaj li 10%, tus nqi ntawm hydrogen chloride (HCl) roj tso tawm loj heev, thiab nws cov ntsiab lus muaj ntau tshaj 100 mg / g, txawm tias nce mus txog 200 rau 300 mg. / g. Nrog rau cov yeeb nkab tuab li thiab qhov muaj mob ntawm cov tshuaj lom neeg xws li H2S thiab CO rau tib neeg lub cev, nyob rau hauv qhov chaw nqaim nqaim, cov neeg raug teeb meem tsis tuaj yeem khiav qhov chaw ntawm qhov hluav taws kub. Raws li cov hluav taws tua hluav taws cov ntaub ntawv pov thawj, qhov teebmeem no nyob rau hauv "kev tsim txom theem ob" 70% txog 80% ntawm tag nrho cov kev puas tsuaj nyob hauv qhov hluav taws kub. Nyob rau hauv pes tsawg tus casualties hauv thee mine hluav taws teeb meem nyob rau hauv Suav teb, qhov kev faib ua feem ntawm cov neeg uas raug kev txom nyem los ntawm "lwm yam kev phem" kuj tseem loj heev.


Thaum cov nplaim hluav taws lossis cov nplaim hluav taws xob tsis zoo, xws li ib lub xov tooj raug kub nyhiab, nws ua pa luam yeeb, CO, HC1 thiab lwm yam roj toxic. Yuav kom tsis txhob los sis txo qhov "raug mob theem siab" ntawm kev raug mob hluav taws, lub International Electrotechnical Commission (IEC) tau ua tiav xyoo 1982 thiab 1989. IEC 60754-1 thiab IEC 60754-2 tau tsim thiab kho dua kom txo cov roj tso tawm los ntawm kev sib txuas ntawm cables (teev HC1 cov ntsiab lus <5 mg="" g,="" ph="" ntawm="" aqueous="" cov="" kev="" daws="" ntawm="" cov="" roj="" ntsha="" corrosive="" tso="" tawm="" los="" ntawm="" combustion="">> 4.3, Tus cwjpwm <10 tts=""> Hauv xyoo 1991, IEC61034 kuj raug tsim los txo cov pa luam yeeb tawm thaum lub kab hluav taws kub (qhia txog kev haus luam yeeb tawm> 60%). Lub tebchaws United Kingdom tau txhim kho cov qauv txheej txheem navy NES-718 thiab NES-713. US Navy Txheem MILS24643 siv ncaj qha siv NES-713 tus qauv txhawm rau txhawm rau txhawm rau tso cov pa nkev uas tso tawm thaum cable tau hlawv (teev qhov tshuaj lom to index <>


Tag nrho cov qauv no muab kev ruaj ntseg thiab ruaj khov rau kev txwv cov pa luam yeeb thiab cov pa roj carbon monoxide poisons los ntawm cov hluav taws kub nyhiab lossis tsis muaj hluav taws kub nyhiab xws li cables. Txawm li cas los xij, nyob rau hauv cov lag luam muaj feem xyuam xws li cov mines me, peb lub teb chaws cov kab hluav taws mining cab tsis muaj pa luam yeeb tsawg tsawg thiab muaj qaug tshuaj tsawg (Halogen) Kev tswj nyob tsis muaj dab tsi.


Qhov uas tsis tshua muaj pa taws, tsawg-halogen nplaim hluav taws xob-siv hluav taws xob tsawg siv cov thooj av me vim muaj kub hnyiab dua thaum lub nplaim hluav taws xob cov hluav taws kub kub. Qhov ntawd yog qhov low-halogen low-halogen nplaim hluav taws xob ua haujlwm rau cov mines txo los yog txo qhov kev raug mob theem ob los ntawm kev kub ntxhov. "; Tib lub sij hawm kev ua tau raws li cov cai ntawm pob zeb cov ntaub ntawv cable, yog lub ntsiab tseem ceeb ntawm lub neej yav tom ntej.

Nws yog ib qho tseem ceeb thiab tseem ceeb heev kom tsim muaj thiab siv cov pa hluav taws tsawg, cov hluav taws uas muaj roj tsawg (hluav taws xob) (halogen) hluav taws xob rau cov pob zeb me.
