Puas muaj kev nyab xeeb rau kev nqus cov sulfur hexafluoride?

2023-08-21 IB

1. Puas yog hexafluoride lom?

Sulfur hexafluorideyog physiologically inert thiab suav hais tias yog ib qho inert gas nyob rau hauv pharmacology. Tab sis thaum nws muaj impurities xws li SF4, nws dhau los ua tshuaj lom. Thaum nqus tau siab ntawm SF6, cov tsos mob ntawm asphyxia xws li dyspnea, hawb pob, xiav ntawm daim tawv nqaij thiab mucous daim nyias nyias, thiab cov convulsions yuav tshwm sim.

2. Puas yog sulfur hexafluoride ua rau koj lub suab qis?

Lub suab hloov ntawmsulfur hexafluoridetsuas yog qhov ntxeev ntawm lub suab hloov ntawm helium, thiab lub suab yog ntxhib thiab qis. Thaum nqus tau cov sulfur hexafluoride, sulfur hexafluoride yuav ua rau lub suab nyob ib puag ncig. Thaum peb ua suab nrov thiab lub suab qaum vibrate, qhov uas tau tsav mus rau vibrate tsis yog huab cua peb feem ntau hais tab sis sulfur hexafluoride. Vim tias qhov hnyav molecular ntawm sulfur hexafluoride loj dua qhov nruab nrab molecular hnyav ntawm huab cua, qhov zaus ntawm kev vibration yog qis dua li ntawm huab cua, yog li ntawd yuav muaj lub suab sib sib zog nqus thiab tuab dua li niaj zaus.

3. Lub sijhawm siv tau ntev npaum li cas ntawm sulfur hexafluoride?

Lub txee lub neej ntawm sulfur hexafluoride microbubbles hauv qab xoom yog 1 xyoos.

4. Puas yog sulfur hexafluoride phem dua cov pa roj carbon dioxide?

SF 6sulfur hexafluoridekuj yog cov muaj zog tshaj lub tsev cog khoom roj. Piv nrog rau cov paub CO2 carbon dioxide, qhov kev siv ntawm SF6 sulfur hexafluoride yog 23,500 npaug ntawm CO2 carbon dioxide. Tsis tas li ntawd, SF6 sulfur hexafluoride tsis tuaj yeem decomposed lawm. Lub zog tuaj yeem kav ntev tshaj li ib txhiab xyoo; cov yam ntxwv ntawm kev pheej yig thiab siv tau yooj yim, ua ke nrog cov yam ntxwv ntawm kev muaj peev xwm nyob rau ntau txhiab xyoo yam tsis muaj kev puas tsuaj ntuj tsim, ua rau cov pa roj no yog qhov tsis zoo tshaj plaws thiab muaj kuab paug loj tshaj plaws hauv "tsim hluav taws xob ntsuab".

5. Qhov hnyav npaum li cas yog sulfur hexafluoride ntau dua li cov pa uas peb nqus tau?

SF6 roj yog tsis muaj xim, tsis paub, tsis muaj tshuaj lom, tsis-flammable, thiab ruaj khov roj. SF6 yog cov roj hnyav hnyav, uas yog kwv yees li 5 npaug hnyav dua li huab cua raws li tus qauv.

6. Puas yog sulfur hexafluoride yog tshuaj?

Cov kev mob tshwm sim ntawm sulfur hexafluoride rau tib neeg lub cev feem ntau yog mob me thiab luv luv, thiab tuaj yeem rov zoo tau yam tsis muaj sequelae. Sulfur hexafluoride yog ib qho tshuaj ntsuam xyuas siv hauv kev kuaj xyuas ultrasound, echocardiography, thiab vascular Doppler kev kuaj mob txhawm rau txhim kho kev txheeb xyuas tus kab mob. Sulfur hexafluoride yog siv rau kev kuaj mob ultrasonic thiab yuav tsum tau siv rau hauv cov tsev kho mob uas muaj xwm txheej ceev thiab nruab nrog cov neeg ua haujlwm cawm, thiab nws yuav tsum tau txhaj tshuaj los ntawm kws kho mob. Yog tias muaj kev tsis haum tshuaj tshwm sim thaum lossis tom qab siv sulfur hexafluoride, nws yuav tshwm sim raws li daim tawv nqaij erythema, bradycardia, hypotension thiab txawm tias anaphylactic shock. Yog tias koj muaj cov tsos mob ntawm lub cev thiab qhov tsis xis nyob hauv zos, koj yuav tsum ceeb toom rau tus kws kho mob tam sim ntawd lossis mus rau hauv tsev kho mob kom kuaj xyuas. Tom qab noj cov tshuaj, nws yog ib qho tsim nyog yuav tsum tau soj ntsuam hauv lub tsev kho mob uas cuam tshuam rau ib nrab teev kom tsis txhob muaj kev fab tshuaj. Kev siv sulfur hexafluoride hauv cov neeg mob uas muaj kab mob plawv tuaj yeem ua rau mob plawv.
