Kodi ndizotetezeka kutulutsa sulfure hexafluoride?
1. Kodi hexafluoride ndi yakupha?
Sulfure hexafluoridendi physiologically inert ndipo imatengedwa ngati mpweya wosagwira ntchito mu pharmacology. Koma ikakhala ndi zonyansa monga SF4, imakhala chinthu chapoizoni. Pokoka mpweya wambiri wa SF6, zizindikiro za asphyxia monga dyspnea, kupuma, khungu la buluu ndi mucous nembanemba, komanso kugwedezeka kwapadera kumachitika.
2. Kodi sulfur hexafluoride imapangitsa mawu anu kukhala otsika?
Kusintha kwa mawusulfure hexafluoridendizosiyana kwambiri ndi kusintha kwa phokoso la helium, ndipo phokoso limakhala lopweteka komanso lochepa. Sulfur hexafluoride ikakokedwa, sulfure hexafluoride imadzaza zingwe za mawu zozungulira. Pamene tipanga phokoso ndi zingwe za mawu zikunjenjemera, chimene chimasonkhezeredwa kunjenjemera si mpweya umene timalankhula kaŵirikaŵiri koma sulfur hexafluoride. Chifukwa kulemera kwa molekyulu ya sulfure hexafluoride ndi yayikulu kuposa kuchuluka kwa mpweya wa mpweya, kugwedezeka kwafupipafupi kumakhala kotsika kusiyana ndi mpweya, kotero padzakhala phokoso lakuya ndi lozama kuposa nthawi zonse.
3. Kodi nthawi yovomerezeka ya sulfur hexafluoride ndi yayitali bwanji?
Nthawi zonse alumali moyo wa sulfure hexafluoride microbubbles pansi pa ziro ndi chaka chimodzi.
4. Kodi sulfure hexafluoride ndi woipa kuposa carbon dioxide?
SF6sulfure hexafluoridendi gasi wamphamvu kwambiri wodziwika wowonjezera kutentha. Poyerekeza ndi CO2 wodziwika bwino wa carbon dioxide, mphamvu ya SF6 sulfure hexafluoride ndi 23,500 nthawi ya CO2 carbon dioxide. Kuphatikiza apo, SF6 sulfure hexafluoride siingawoledwe mwachilengedwe. Chikokacho chingakhalepo kwa zaka zoposa chikwi; mawonekedwe a kukhala otsika mtengo komanso osavuta kugwiritsa ntchito, kuphatikiza ndi mikhalidwe yotha kukhalapo kwa zaka masauzande ambiri popanda kuwonongeka kwachilengedwe, zimapangitsa kuti mpweyawu ukhale wonyalanyazidwa komanso wodetsa kwambiri mu "green power generation".
5. Kodi sulfure hexafluoride ndi yolemera bwanji kuposa mpweya umene timapuma?
Mpweya wa SF6 ndi wopanda mtundu, wosadziwa, wopanda poizoni, wosayaka, komanso mpweya wokhazikika. SF6 ndi mpweya wolemera kwambiri, womwe umakhala wolemera kasanu kuposa momwe mpweya umakhalira.
6. Kodi sulfur hexafluoride ndi mankhwala?
Zotsatira za sulfure hexafluoride pathupi la munthu nthawi zambiri zimakhala zofatsa komanso zazifupi, ndipo zimatha kuchira popanda sequelae. Sulfur hexafluoride ndi mankhwala ozindikira omwe amagwiritsidwa ntchito poyesa kujambula kwa ultrasound, echocardiography, ndi vascular Doppler mayeso kuti athe kuzindikira matenda. Sulfur hexafluoride imagwiritsidwa ntchito pozindikira matenda a akupanga ndipo imayenera kugwiritsidwa ntchito m'mabungwe azachipatala omwe ali ndi vuto ladzidzidzi komanso okhala ndi opulumutsa, ndipo imayenera kubayidwa ndi dokotala. Ngati matupi awo sagwirizana zimachitika kapena pambuyo ntchito sulfure hexafluoride, izo kusonyeza khungu erythema, bradycardia, hypotension ngakhale anaphylactic mantha. Ngati muli ndi zizindikiro za kusapeza bwino kwadongosolo komanso kwanuko, muyenera kudziwitsa dokotala mwachangu kapena kupita kuchipatala kuti mukayesedwe. Mukatha kumwa mankhwalawa, ndikofunikira kuyang'ana ku chipatala choyenera kwa theka la ola kuti mupewe ziwengo. Kugwiritsa ntchito sulfure hexafluoride kwa odwala omwe ali ndi matenda amtima kungayambitse matenda a mtima.
