1. Hexafluoride ine chepfu here?

Sulfur hexafluorideis physiologically inert uye inoonekwa seinert gasi mupharmacology. Asi kana iine tsvina yakaita seSF4, inova chinhu chine muchetura. Paunenge uchifema huwandu hwepamusoro hweSF6, zviratidzo zveasphyxia senge dyspnea, wheezing, ganda rebhuruu uye mucous membranes, uye general convuls inogona kuitika.

2. Sulfur hexafluoride inoita kuti inzwi rako ridzike here?

Kuchinja kwenzwi kwesarufa hexafluoridezvinongopesana nekuchinja kweruzha rwehelium, uye ruzha rwakashata uye rwakaderera. Kana sarufa hexafluoride ikafemerwa, sarufa hexafluoride inozadza tambo dzezwi dzakapoteredza. Patinoita ruzha uye tambo dzezwi dzobvunda, chinosundwa kuti chidengenyeke haisi mhepo yatinowanzotaura asi sulfur hexafluoride. Nekuda kwekuti huremu hwesarufa hexafluoride hwakakura kupfuura avhareji yehuremu hwemhepo, kuwanda kwekuzunguza kwakadzikira pane kwemhepo, saka pachave nekudzika uye kwakakora ruzha kupfuura mazuva ese.

3. Yakareba sei nguva yechokwadi yesulfure hexafluoride?

Hupenyu hwesherufu hwesarufa hexafluoride microbubbles pazasi zero igore rimwe.

4. Sulfur hexafluoride yakaipa here kupfuura carbon dioxide?

SF6sarufa hexafluoridendirowo gasi regreenhouse rakasimba rinozivikanwa. Kuenzaniswa neyakajairwa CO2 carbon dioxide, kusimba kweSF6 sulfur hexafluoride ndeye 23,500 nguva yeCO2 carbon dioxide. Pamusoro pezvo, SF6 sulfur hexafluoride haigone kuoreswa zvoga. Pesvedzero inogona kugara kweanopfuura makore ane chiuru; maitiro ekuve akachipa uye ari nyore kushandisa, pamwe chete nehunhu hwekukwanisa kuvapo kwezviuru zvemakore pasina kuora kwechisikigo, inoita kuti gasi iri rive rakanyanya kuregeredzwa uye rakanyanya kusvibiswa mu "green power generation".

5. Sulfur hexafluoride inorema zvakadii pane mweya watinofema?

SF6 gasi haina ruvara, isingazivi, haina chepfu, isingabatike, uye yakagadzikana gasi. SF6 igasi rinorema, rinorema kakapetwa kashanu pane mhepo pasi pemamiriro ezvinhu.

6. Sulfur hexafluoride mushonga here?

Mhedzisiro yesarufa hexafluoride pamuviri wemunhu inowanzo nyoro uye kwenguva pfupi, uye inogona kupora yega pasina sequelae. Sulfur hexafluoride mushonga wekuongorora unoshandiswa mukuongorora kwe ultrasound imaging, echocardiography, uye vascular Doppler bvunzo kuvandudza kuzivikanwa kwechirwere. Sulfur hexafluoride inoshandiswa pakuongorora kwe ultrasonic uye inoda kushandiswa muzvipatara zvine mamiriro ekukurumidzira uye ine vashandi vekununura, uye inoda kubaiwa nachiremba. Kana allergic reaction ikaitika panguva kana mushure mekushandisa sulfur hexafluoride, icharatidza seganda erythema, bradycardia, hypotension uye kunyange anaphylactic shock. Kana iwe uine systemic uye yemunharaunda kusagadzikana zviratidzo, iwe unofanirwa kukurumidza kuzivisa chiremba kana kuenda kuchipatara kunoongororwa. Mushure mekutora mushonga, zvinodikanwa kuti ucherechedze mune yakakodzera nzvimbo yekurapa kwehafu yeawa kudzivirira allergic reactions. Kushandiswa kwesarufa hexafluoride kune varwere vane chirwere chemwoyo chinogona kuwedzera chirwere chemwoyo.
