Kuvhiya kunotevera kunorambidzwa kune avo vanga vachigara mu laboratory gore rose.Xiao Bian akazvironga nhasi uye nekukasira kuendesa kune wese munhu kuti adzidze!
1. Firiji bhomba
Munguva yekubvisa kana dialysis, organic reagents anoshandiswa uye anoiswa mufiriji yakavhurika.Sezvo iyo organic gasi inosvika payakaomesesa, inobatidzwa nemagetsi spark kana firiji compressor yatangwa.
Pana October 6, 1986, firiji yeimwe nzvimbo yokutsvakurudza yeChinese Academy of Sciences yakaputika;
Pana December 15, 1987, firiji murabhoritari yeNingxia Academy of Agricultural Sciences yakaputika;
Musi waChikunguru 20, 1988, firiji ye "Shasong" mumba memudzidzisi weNanjing Normal University yakaputika.
Mumakore mashomanene chete, kwakashumwa kuputika kwefiriji kunopfuura gumi.Chikonzero chetsaona chaive chisiri chemhando yefiriji pachayo, asi makemikari akadai sepetroleum ether, acetone, benzene uye butane gasi akaiswa mufiriji.Tinoziva kuti tembiricha iri mufiriji yakaderera.Kana makemikari anopisa uye anoputika ane nzvimbo yakaderera yekubikira uye flash point akaiswa mufiriji, anopisa gasi rinopfuta pasi pemamiriro ekushisa akaderera.Kunyangwe kana chivharo chebhodhoro chakanyatsomonyoroka, tembiricha yakaderera inowanzoita kuti goko rebhodhoro ridzikire, vharafu yegasi isunungure kana kunyange bhodhoro rebhodhoro richitsemuka.Gasi rinopisa rinopisa rinosanganiswa nemhepo kuti riite musanganiswa unoputika uye rinozadza firiji.Iyo spark yemagetsi inogadzirwa kana tembiricha yekudzora switch (kana imwe control switch) yakavhurwa kana kuvharwa zviri nyore kuputika.Naizvozvo, vashandisi vefiriji havafanire kuchengeta makemikari mufiriji.
2. Dururira doro nemoto wakashama
Vhura kupisa kunopisa kwemwenje wedoro nemapini, uye udururire doro mumwenje wedoro neruoko rumwe, izvo zvingaita kuti bhodhoro rose redoro ripise uye rinoputika.
3. Liquid nitrogen bhomba
Shandisa girazi uye chivharo chinovhara centrifuge machubhu kurongedza sampuli woisa mumatangi enitrogen emvura.Pavanenge vachibudiswa kunze, zvinhu zvemadziro epombi zvakashanduka, uye hazvigoni kumira kuwedzera kwegesi gasi, kana kuti kudzvinyirira hakuna kuenzana pavanenge vachikurumidza kupisa, zvichikonzera kuputika.
Naizvozvo, vanhu vanopfeka magirazi vane mukana - "Magirazi enguva refu!"
Vashandi vanogara vachiita nitrogen yemvura vanofanira kupfeka magirazi epurasitiki.
Hazard Overview
Dambudziko rehutano: Ichi chigadzirwa hachipisi uye chinofemesa, uye kusangana kweganda nenitrogen yemvura kunogona kukonzera chando.Kana iyo nitrogen inogadzirwa ne vaporization yakawandisa pasi petembiricha yakajairwa, kumanikidzwa kweokisijeni mumhepo kunodonha, zvichikonzera anoxic asphyxia.
Matanho ekubatsira kwekutanga
Kubata ganda: Kana paine chando, tsvaga kurapwa.
Inhalation: kurumidza kusiya saiti kune mweya mutsva uye ramba uchifema zvakanaka.Kana kufema kwakaoma, ipa oxygen.Kana kufema kwakamira, ita kufema kwemaitiro nekukasika uye tsvaga rubatsiro kuna chiremba.
Zviyero zvekudzima moto
Njodzi: Kana kupisa, kumanikidzwa kwemukati kwemudziyo kunowedzera, izvo zvinogona kukonzera kuputika uye kuputika.
Nzira yekudzima: Ichi chigadzirwa hachibatike, uye midziyo iri munzvimbo yemoto inofanira kuchengetwa ichitonhorera nemvura ine mhute.Iyo vaporization yemvura nitrogen inogona kukwidziridzwa nekupfapfaidza mvura nenzira yemhute, uye pfuti yemvura haifaniri kupfura nitrogen yemvura.
Leakage emergency treatment
Emergency kurapwa: kurumidza bvisa vashandi munzvimbo yakasvibiswa kuenda kunzvimbo inoenda nemhepo, vovaparadzanisa, uye rambidza kupinda.Vashandi vekukurumidzira vachapfeka-yega-ine yakanaka yekufemesa uye zvipfeko zvinotonhora.Usabata iyo leakage zvakananga.Cheka iyo leakage source zvakanyanya sezvinobvira.Dzivirira gasi kuungana munzvimbo dzakaderera uye kuputika kana wasangana nenzvimbo yekupisa.Shandisa exhaust fan kutumira gasi rakadeuka panzvimbo yakavhurika.Midziyo iri kubuda mvura inofanira kunyatsogadziriswa, kugadziriswa uye kuongororwa isati yashandiswa.
Kubata uye kuchengetedza
Kuchengetedza kwekushanda: kushanda kwakavharwa, kupa mamiriro akanaka emhepo yemhepo.Vashandi vanofanira kudzidziswa uye kunyatsotevedzera maitiro ekushanda.Zvinokurudzirwa kuti vashandi vapfeke magirovhosi anotonhora.Dzivirira kubuda kwegasi mumhepo yenzvimbo yebasa.Masilinda uye zvishongedzo zvinofanirwa kubatwa nekuchenjerera kudzivirira kukuvara.Shongedza midziyo yekukurumidzira yekudonha.
Kuchengetedza kuchengetedza: Chengetedza munzvimbo inotonhorera uye ine mhepo yakanaka, uye tembiricha haifanire kudarika 50 ℃.
Kudzivirirwa pachako
Dziviriro yekufema system: hapana kuchengetedzwa kwakakosha kunodiwa kazhinji.Nekudaro, kana mweya weokisijeni wemhepo munzvimbo yebasa wakadzikira kupfuura 19%, zvinofema mweya, maokisijeni ekufema uye marefu echubhu masks anofanirwa kupfekwa.
Dziviriro yeziso: pfeka mask yekuchengetedza.
Kudzivirirwa kwemaoko: pfeka magirovhosi anotonhora.
Kumwe Kudzivirirwa: Dzivisa kufemerwa nemhepo yakakwira kudzivirira chando.
