SF6, tseem hu ua sulfur hexafluoride, yog qhov tsis muaj tshuaj lom, tab sis yog tias nws qhov zoo tsis huv los yog nws tawg mus rau hauv cov tshuaj fluorine sib txawv nyob rau hauv qhov kev txiav txim ntawm arc, xws li sulfuryl fluoride, sulfuryl fluoride, sulfur tetrafluoride, hydrofluoric acid, thiab lwm yam. ., nws muaj qhov sib txawv toxicity.
Cov pa ntshiab sulfur hexafluoride tsis muaj xim, tsis muaj ntxhiab, thiab tsis muaj tshuaj lom nyob rau hauv chav tsev kub. Nws yog ib qho tshuaj ruaj khov halogen compound nrog zoo rwb thaiv tsev thiab arc extinguishing zog.
1. Fluorinated sulfuryl
Nws belongs rau cov roj tsis muaj xim thiab pob tshab nrog cov khoom siv tshuaj lom neeg ruaj khov thiab muaj tshuaj lom heev. Thaum cov tsiaj sim, nws tuaj yeem ua pa thiab tuag vim mob ntsws ntsws;
2. Sulfuryl fluoride
Nyob rau hauv chav tsev kub, nws yog ib qho roj thiab tshuaj lom. Kev nqus pa ntau dhau tuaj yeem ua rau muaj mob hauv lub ntsws, thymus, thiab meninges, feem ntau ua rau qaug dab peg thiab tuag rau lub sijhawm no;
3. Sulfur tetrafluoride
Nyob rau hauv chav tsev kub, nws yog ib qho tsis muaj xim thiab pungent roj uas yooj yim ua ke nrog dej los tsim cov pa luam yeeb, uas yooj yim nqus tau los ntawm tib neeg lub cev thiab nkag mus rau hauv lub ntsws, ua rau lub ntsws puas thiab ua rau cov kab mob ua pa;
4. Hydrofluoric acid
Hydrofluoric acid yog ib qho txaus ntshai heev thiab muaj kuab lom inorganic acid, dav siv hauv kev lag luam thiab lub neej txhua hnub. Hydrofluoric acid muaj zog corrosiveness thiab tuaj yeem ua rau kub hnyiab. Nws toxicity thiab cov ntaub so ntswg nkag mus tau muaj zog, thiab txawm me me ntawm hydrofluoric acid burns tuaj yeem ua rau tuag nyob rau lub sijhawm luv luv.
SF6 yog ib qho roj inert uas muaj rwb thaiv tsev zoo heev thiab tsis tuaj yeem ignited. Ntshiab SF6 tsis muaj tshuaj lom, tab sis tom qab electrolysis, nws tso tawm cov tshuaj lom neeg uas tuaj yeem ua rau mob qog noj ntshav thiab ua rau lub siab puas tsuaj.
Yog li ntawd, thaum nyob rau hauv ib puag ncig sulfur hexafluoride roj, kom tsis txhob nws cov arc extinguishing toxicity, nws yog ib qhov tsim nyog yuav tsum tam sim ntawd tawm ntawm sulfur hexafluoride roj ib puag ncig thiab qhib qhov rais rau qhov cua kom ceev cov pa diffusion.
