Le misebenzi ilandelayo ayivumelekanga kwabo bahlala elabhoratri unyaka wonke.UXiao Bian uzilungelelanise namhlanje kwaye ngokukhawuleza wazithumela kuye wonke umntu ukuba afunde!
1. Ibhombu yefriji
Ngethuba lokukhutshwa okanye i-dialysis, i-reagents ye-organic isetyenziswa kwaye ifakwe kwifriji evulekile.Njengoko igesi yezinto eziphilayo ifikelela kugxininiso olubalulekileyo, lutshiswa yintlantsi yombane xa icompressor yefriji iqaliswa.
Ngo-Oktobha 6, 1986, ifriji kwiziko lophando leZiko leeSayensi laseTshayina laqhushumba;
NgoDisemba 15, 1987, ifriji ekwilabhoratri yeNingxia Academy of Agricultural Sciences yaqhushumba;
NgoJulayi 20, 1988, ifriji "Shasong" kwikhaya lomfundisi-ntsapho waseNanjing Normal University yaqhuma.
Kwiminyaka nje embalwa, kuye kwakho ingxelo yokudubula kweefriji ezingaphezu kwe-10.Unobangela wengozi ibingengomgangatho wefriji ngokwawo, kodwa imichiza efana nepetroleum ether, iacetone, benzene kunye negesi yebutane zafakwa efrijini.Siyazi ukuba iqondo lobushushu kwifriji liphantsi.Ukuba iikhemikhali ezinokutsha kunye neziqhumayo ezinendawo yokubila ephantsi kunye ne-flash point zibekwe efrijini, ziya kutshisa igesi enokutsha phantsi kweemeko zobushushu obuphantsi.Nokuba umnqwazi webhotile ujijene ngokuqinileyo, ubushushu obuphantsi buhlala bubangela ukuba iqokobhe lebhotile licuthe, ivalve yegesi ikhululeke okanye iqokobhe lebhotile liqhekeke.Irhasi evuthayo evuthayo ixuba nomoya ukwenza umxube oqhumayo kwaye izalise ifriji.I-spark yombane eyenziwe xa ukutshintshwa kokulawula ubushushu (okanye ezinye iiswitshi zokulawula) zivuliwe okanye zivaliwe kulula kakhulu ukuqhuma.Ngoko ke, abasebenzisi befriji akufanele bagcine imichiza efrijini.
2. Galela utywala ngomlilo ovulekileyo
Vula i-twist evuthayo yesibane sotywala kunye ne-pliers, kwaye ugalele utywala kwisibane sotywala ngesandla esinye, esinokubangela ukuba ibhotile yotywala ivuthe kwaye iqhume.
3. Ibhombu yenitrogen engamanzi
Sebenzisa iglasi kunye neetyhubhu zokugquma i-centrifuge ukupakisha iisampulu kwaye uzifake kwiitanki zenitrogen ezingamanzi.Xa zikhutshwe, iipropati zodonga lombhobho zitshintshile, kwaye azikwazi ukumelana noxinzelelo lwegesi olukhulayo, okanye uxinzelelo alufani xa lufudumala ngokukhawuleza, lubangela ukuqhuma.
Ngoko ke, abantu abanxiba iiglasi banenzuzo - "Iiglasi ezihlala ixesha elide!"
Abaqhubi abasoloko bekhupha initrogen engamanzi baya kunxiba iiglasi zeplastiki.
NONE
Ingozi empilweni: Le mveliso ayitshi kwaye ayiphefumli, kwaye ukudibana kwesikhumba nenitrogen engamanzi kunokubangela iqabaka.Ukuba i-nitrogen eveliswa ngumphunga igqithise kakhulu phantsi kobushushu obuqhelekileyo, uxinzelelo lwe-oksijini emoyeni luya kuhla, lubangele i-anoxic asphyxia.
Amanyathelo oncedo lokuqala
Uqhagamshelwano lwesikhumba: Ukuba kukho iqabaka, funa unyango.
Ukuphefumla: khawuleza ushiye indawo emoyeni omtsha kwaye ugcine ukuphefumla kakuhle.Ukuba ukuphefumla kunzima, nika ioksijini.Ukuba ukuphefumla kuyeka, yenza ukuphefumla okwenziwayo ngoko nangoko kwaye ufune iingcebiso kugqirha.
Amanyathelo okulwa nomlilo
Ingozi: Kwimeko yobushushu, uxinzelelo lwangaphakathi lwesikhongozeli luya kunyuka, olunokubangela ukuqhekeka kunye nokudubula.
Indlela yokucima: Le mveliso ayinakutsha, kwaye izitya ezikwindawo yomlilo ziya kugcinwa zipholile ngamanzi anenkungu.I-vaporization ye-nitrogen engamanzi inokukhawuleziswa ngokutshiza amanzi ngendlela yenkungu, kwaye umpu wamanzi awuyi kudubula i-nitrogen engamanzi.
Ukuvuza unyango olungxamisekileyo
Unyango olungxamisekileyo: bakhuphe ngokukhawuleza abasebenzi abakwindawo evuzayo engcolisekileyo uye kwindawo engasemoyeni, ubabeke bodwa, kwaye uthintele ukufikelela.Abasebenzi bexesha likaxakeka baya kunxiba izixhobo zokuphefumla ezizimeleyo kunye nempahla ebandayo.Musa ukubamba ukuvuza ngokuthe ngqo.Sika umthombo wokuvuza kangangoko.Thintela irhasi ekuhlanganeni kwindawo ephantsi kunye nokugqabhuka xa idibana nomthombo wobushushu.Sebenzisa ifeni yokukhupha igesi ukuthumela irhasi evuzayo kwindawo evulekileyo.Izikhongozeli ezivuzayo kufuneka ziphathwe kakuhle, zilungiswe kwaye zihlolwe phambi kokuba zisetyenziswe.
Ukuphatha kunye nokugcinwa
Izilumkiso zokusebenza: ukusebenza okuvaliweyo, ukubonelela ngeemeko ezilungileyo zendalo zomoya.Abanini-zithuthi kufuneka baqeqeshwe kwaye bathobele ngokungqongqo iinkqubo zokusebenza.Kucetyiswa ukuba abaqhubi banxibe iiglavu zobungqina obubandayo.Thintela ukuvuza kwerhasi emoyeni kwindawo yokusebenza.Iisilinda kunye nezixhobo ziya kuphathwa ngononophelo ukukhusela umonakalo.Xhobisa izixhobo zikaxakeka zokuvuza.
Amanyathelo okugcina: Gcina kwindawo epholileyo nengena umoya, kwaye ubushushu akufunekanga budlule kwi-50 ℃.
Ukhuseleko lomntu
Ukukhuselwa kwenkqubo yokuphefumula: akukho khuseleko olulodwa olufunekayo ngokubanzi.Nangona kunjalo, xa umoya weoksijini womoya kwindawo yokusebenza ungaphantsi kwe-19%, iziphefumlo zomoya, iziphefumlo zeoksijini kunye nemaski ende yeetyhubhu kufuneka zinxitywe.
Ukhuseleko lwamehlo: nxiba imaski yokhuseleko.
Ukukhuselwa kwesandla: nxiba iiglavu zobungqina obubandayo.
Olunye ukhuseleko: Kuphephe ukuphefumla umoya woxinzelelo oluphezulu ukuthintela iqabaka.
