I-Nitrous oxide (N2O)

Imingcele Yezobuchwepheshe

I-nitrous oxide iyinto engaphili enefomula yamakhemikhali ethi N2O. Eyaziwa nangokuthi igesi ehlekayo, igesi elingenambala nelimnandi, i-oxidant engakwazi ukusekela ukuvutha ngaphansi kwezimo ezithile (okufana ne-oxygen, ngoba igesi ehlekayo ingabola ibe yi-nitrogen ne-oksijini emazingeni okushisa aphezulu), kodwa izinzile ekamelweni lokushisa kancane Inomphumela wokubulala izinzwa futhi ingabangela ukuhleka. I-nitrous oxide iyancibilika emanzini, i-ethanol, i-ether ne-concentrated sulfuric acid, kodwa ayiphenduli emanzini. I-nitrous oxide ingasetshenziswa njenge-racing propellant, i-rocket oxidizer, nokwandisa ukuphuma kwenjini; i-anesthesia yokuhlinzwa kanye yamazinyo; embonini yokudla, i-nitrous oxide ingasetshenziswa njengesengezo sokwenza amagwebu obisi nokwenza ikhofi; manje i-Laughing gas isetshenziswa ezindaweni eziningi zokuzijabulisa. I-high-purity nitrous oxide (igesi ehlekayo) isetshenziswa kakhulu kudokotela wamazinyo, ukuhlinzwa, ukubelethisa kanye ne-gynecology ukuze kutholwe izinzwa, ukutholwa kokuvuza, iziqandisi, izinsiza ezivuthayo, izilondolozi, izinto zokusetshenziswa zamakhemikhali, igesi ye-atomic absorption spectroscopy, igesi ebhalansi yokukhiqiza i-semiconductor, indawo yokwelapha ye-semiconductor, ukwelashwa okujwayelekile kwe-oxid, umhwamuko we-oxid. fafaza, ivacuum kanye nokutholwa kokuvuza komfutho. Ukwelashwa kwezimo eziphuthumayo zokuvuza: khipha ngokushesha abasebenzi endaweni engcolile uye emoyeni ongaphezulu, futhi ubahlukanise, ukhawule ukufinyelela. Kutuswa ukuthi abasebenzi bezimo eziphuthumayo bagqoke amathuluzi okuphefumula okuphefumula kahle ezimele kanye nezingubo zokusebenza ezijwayelekile. Sika umthombo wokuvuza ngangokunokwenzeka. Ukungena komoya okunengqondo ukusheshisa ukusabalalisa. Iziqukathi ezivuzayo kufanele ziphathwe kahle futhi zisetshenziswe ngemva kokulungiswa nokuhlolwa. Indlela yokucisha umlilo: Lo mkhiqizo awukwazi ukuvutha. Izicishamlilo kufanele zigqoke izifihla-buso zegesi kanye namasudi okucisha umlilo aphelele. Sebenzisa inkungu yamanzi ukuze ugcine izitsha ezisendaweni yomlilo zipholile. Sika umthombo wegesi ngokushesha, vikela izisebenzi ezinqamule umthombo wegesi ngesifutho samanzi, bese ukhetha isicisha-mlilo esifanele ukuze ucime umlilo ngokwembangela yomlilo.

Isicelo:

①Okwezokwelapha:

isetshenziswa njengephethiloli yegesi ngesilinganiso esingu-2:1 nomoya-mpilo wemithi yokubulala izinzwa enamandla njenge-sevoflurane noma i-desflurane.

②I-elekthronikhi:

isetshenziswa ngokuhlangana ne-silane ukuze kufakwe umhwamuko wamakhemikhali wezingqimba ze-silicon nitride; ibuye isetshenziselwe ekucubunguleni okushisayo okusheshayo ukuze kukhule ama-oxide asesangweni aphezulu.

Iphakheji evamile:

Inzuzo:

① Ngaphezu kweminyaka eyishumi emakethe;

②ISO umenzi wesitifiketi;

③Ukulethwa okusheshayo;

④Umthombo wezinto ezingavuthiwe ozinzile;

⑤Isistimu yokuhlaziya eku-inthanethi yokulawula ikhwalithi kuso sonke isinyathelo;

⑥Isidingo esiphezulu kanye nenqubo yokucophelela yokuphatha isilinda ngaphambi kokugcwalisa;
