Zvimwe zvinotsanangurwa zvekurongedza zvinogona kupihwa zvinoenderana nezvinodiwa nevatengi

99.999% kuchena Liquid Oxygen O2 YeIndasitiri

Oxygen igasi risina ruvara, risinganhuhwi, risingaravi. Hukama hwegasi (air=1) pa21.1°C uye 101.3kPa i1.105, uye density yemvura pakuvira i1141kg/m3. Okisijeni haina chepfu, asi kuratidzwa kune yakanyanya kuwanda kunogona kukanganisa mapapu uye nechepakati tsinga system. Oxygen inogona kutakurwa nekumanikidzwa kwe13790kPa segasi risina kunyungudutswa kana semvura inoyerera. Mazhinji oxidation maitiro muindasitiri yemakemikari anoshandisa okisijeni yakachena pachinzvimbo chemhepo kuitira kuti ubatsirwe kubva kumazinga epamusoro ekuita, kupatsanurwa kwechigadzirwa kuri nyore, kubuda kwepamusoro kana hukuru hwemidziyo midiki.

Okisijeni inonyanya kushandiswa pakufema. Mumamiriro ezvinhu akajairika, vanhu vanowana oxygen kuburikidza nekufema mweya kuti uenderane nezvinodiwa nemuviri. Nekudaro, mune dzimwe nguva dzakakosha, dzakadai sekuita diving, kukwira makomo, kubhururuka kwepamusoro-soro, kufambisa nzvimbo, uye kununurwa kwekurapa, nekuda kwekushaikwa kwakakwana kana kuperevedza kweokisijeni munharaunda, vanhu vanofanirwa kushandisa okisijeni yakachena kana midziyo yakapfuma. kuchengetedza upenyu. Mamiriro ezvinhu aya anowanzo sanganisira mamiriro akadai sekukwirira, kuderera kwemhepo, kana nzvimbo dzakavharirwa dzinoita kuti kufema kwemhepo kuome kana kusachengeteka. Naizvozvo, munzvimbo idzi chaidzo, okisijeni inova chinhu chakakosha mukuchengetedza kufema kwakajairika mumuviri wemunhu.

Mirayiridzo Yekuchengetedza

Emergency overview: Oxidizing gasi, combustion aid. Iyo humburumbira mudziyo unowanzo kudzvanya kana uchipisa, uye kune njodzi yekuputika. Cryogenic zvinwiwa zviri nyore conductive.Kukonzera chando.
GHS Hazard Kirasi: Zvinoenderana neChemical Classification, Yambiro Label uye Yambiro Specification akatevedzana zviyero, chigadzirwa ndecheoxidizing gasi Kirasi 1; Gasi pasi pekumanikidzwa gasi rakamanikidzwa.
Yambiro izwi: Njodzi
Ruzivo rwengozi: inogona kukonzera kana kuwedzera kupisa; Oxidizing agent; Magasi ari pasi pekumanikidzwa anogona kuputika kana apiswa:
Zvekungwaririra:
Chengetedzo: Chengetedza kure nenzvimbo dzekupisa, marimi akavhurika, uye nzvimbo dzinopisa. Hapana kuputa kumabasa. Mavharuvhu akabatanidzwa, mapaipi, zviridzwa, nezvimwe, zvinorambidzwa zvachose kubva kugirisi. Usashandise midziyo inogona kukonzera sparks. Tora matanho ekudzivirira static magetsi. Zvidzitiro zvepasi uye zvishandiso zvakabatana.

Mhinduro yetsaona: cheka chinobvinza, bvisa njodzi dzese dzemoto, kufefetedza kwakanaka, mhanyisa kupararira.
Kuchengetera kwakachengeteka: Dzivisa chiedza chezuva uye chengeta munzvimbo ine mhepo inofefetera. Chengetedza uri woga kubva kune zvinoderedza maajenti uye zvinobvira moto/zvinopisa.
Disposal: Ichi chigadzirwa kana chigadziko chayo chicharaswa maererano nemitemo yemunharaunda.
Ngozi yepanyama uye yemakemikari: iyo gasi ine kupisa-inotsigira uye oxidizing zvivakwa. Yakamanikidzwa gasi, cylinder mudziyo iri nyore kuwedzeredza kana ichipisa, kune njodzi yekuputika. Kana muromo webhodhoro reokisijeni wakasvibiswa negirizi, kana okisijeni ichikurumidza kubudiswa, girisi inokurumidza oxidize, uye kupisa kunokonzerwa nekupokana pakati pemhepo yekudzvanya kwemhepo uye muromo webhodhoro inowedzera kukurumidza kuita oxidation. girisi yakasvibiswa pabhodhoro reokisijeni kana vharuvhu yekudzikisa inokonzeresa kupisa kana kuputika, okisijeni yemvura imvura yebhuruu yakapfava, uye ine paramagnetism yakasimba.Liquid okisijeni inoita kuti chinhu icho chinobata chiite brittle.

Liquid okisijeni zvakare yakasimba kwazvo oxidizing agent: organic zvinhu zvinopisa zvine chisimba mumvura. Zvimwe zvinhu zvinogona kuputika kana zvakanyudzwa mumvura yeokisijeni kwenguva yakareba, kusanganisira asphalt.

Dambudziko rehutano: Pakumanikidzwa kwakajairika, muchetura weokisijeni unogona kuitika kana huwandu hweokisijeni hunopfuura 40%. Kana 40% kusvika 60% okisijeni ikafemerwa, pane kutadza kugadzikana kweretrosternal, chikosoro chakareruka, uyezve kuomarara kwechipfuva, kunzwa kutsva kwekupisa uye dyspnea, uye kukosora kunowedzera: pulmonary edema uye asphyxia inogona kuitika mumatambudziko akaomarara. Kana mweya weokisijeni uri pamusoro pe80%, tsandanyama dzechiso dzinozununguka, kucheneruka kwechiso, dzungu, tachycardia, kudonha, uyezve muviri wese tonic convulsions, coma, kutadza kufema uye kufa. Kusangana kweganda neokisijeni yemvura kunogona kukonzera chando chakanyanya.
