Application】Inoshandiswa zvakanyanya mumadhorobha, kusanganisira kutungamira, Calcium, magniyum, Sodium, Lithium, Aluminium, uye Nickel Alloys. Inoshandiswa segomba rinodzvinyirira kubvisa gasi magasi akasara mune waya isina waya vacuum machubhu, uye zvakare inoshandiswa mukugadzirwa kwemaronda earium.
Aluminium Thermal Runcountction Nzira: Barium Nitrate yakadhindwa yakadhindwa kuburitsa chiuru oxide. Akanaka kwazvo aluminium inoshandiswa seyekudzora mumiririri, uye huwandu hwezvinhu zvechikamu ndi3bao: 2a1. Barium oxide uye aluminium inotanga kugadzirwa mumapaipi, ayo anobva aiswa mune zvakadaro uye anoiswa kune 1150 ℃ yekudzikisa kushatirwa kure. Kuchena kweiyo legium yakakonzera ndeye 99%.
Kuchengetedza】Dust. Izvo zvinowanzoitika kuDoces yemvura uye kuita nechisimba neacids, kuburitsa hydrogen gasi iyo inogona kuvezwa nekupisa kwekuita. Kusangana neFluorine, chlorine, uye zvimwe zvinhu zvinogona kukonzera maitiro echisimba emakemikari. Barium simbi inokwana nemvura kuti iite iyo Barium Hydroxide, iyo ine maitiro akanganisa. Panguva imwecheteyo, mvura-ine mvura-yemvura leuum pondo ine muchetura zvakanyanya. Ichi chinhu chinogona kunge chiri kukuvadza kune zvakatipoteredza, zvinokurudzirwa kuti usaregedze kupinda nharaunda.
Hazard Code: Chinhu chinopisa chinhu mukubatana nemunyoro. GB 4.3 Kirasi 43009. UN Nhamba 1400. IMDG kodhi 4332 Peji, kirasi 4.3.
Paunenge uchiitora nekukanganisa, inwa yakawanda mvura inodziya, inomutsa kurutsa, geza dumbu ne2% kusvika ku5% sodium sulfate solution, sodie sodium solution, uye tsvaga chirwere chekurapa, uye tsvaga kurapwa. Inhaling guruva inogona kukonzera muchetura. Varwere vanofanirwa kubviswa munzvimbo yakasvibiswa, vakazorora, uye vakaramba vadziya; Kana kufema zvichimira, pakarepo ita kufema kwekufema uye kutsvaga kurapwa. Netsaona muchidimbu mumaziso, suka nemvura yakawanda, tsvaga kurapwa mumatare akanyanya. Ganda rekutaurirana: Svina nemvura kutanga, wozogeza kwazvo nesipo. Kana paine kupisa, tsvaga kurapwa. Pakarepo geza muromo wako kana wapinda nekukanganisa nekutsvaka kurapwa kurapwa.
Paunenge uchibata Barium, zvakafanira kusimbisa iyo yekuchengetedza kuchengetedza matanho evashandi. Yese marara inofanira kurapwa neyebrous sulfate kana sodium sulfate kushandura ane chepfu ndiro barts mune yakaderera solubility.
Vanoshanda vanofanira kupfeka zvekuzvimhanya-pray gomba masokisi, kuchengetedzwa kwemakemikari, zvipfeko zvemakemikari, uye magurovhosi erabha. Ibva kure kubva kunhivi dzemoto uye kupisa, uye kuputa kunorambidzwa zvakanyatso kurambidzwa munzvimbo yebasa. Shandisa kuputika-chiratidzo ventilation system nemidziyo. Dzivisa kusangana nevehudhiyo, Acids, uye zvigadziko, kunyanya nemvura.
Yakachengetedzwa muParaffen uye mvura paraffin, yakarongedzwa mumabhodhoro egirazi neyekuisa nguva yekuisa, ine uremu hwe 1kg pane bhodhoro, uye wobva wanyudzwa mumabhokisi emapuranga akaiswa padding. Panofanirwa kuve nezvinhu zvakajeka "zvinopisa zvinosangana ne unyoro
Chengetedza mune inotonhorera, yakaoma, uye yakadzvanywa isina kuchengetedzwa kwekutambudzika. Ibva kure nekupisa uye moto masosi, dzivirira kunyorova, uye kudzivirira kukuvara kwemidziyo. Usasangana nemvura, asidhi, kana oxidants. Yakaparadzaniswa nenyaya yejekisiki, inopisa, uye zvinhu zvingangoita zverudzi zvekuchengetedza uye zvekufambisa, uye hazvigone kutakurwa pamazuva ekunaya.
Kana paine moto, yakaoma jecha, graphiti graphite poda kana yakaoma poda yekudzima inogona kushandiswa kudzima moto, sologenated hydrocarbon yekudzima mumiririri (yakadai seye 1211 yekuwedzera mumiririri) haibvumirwe.
