Madzi asafe

Madzi asafe ndi inert, colorless ndi odorless mpweya. Iye sanali zikuwononga, si flammable. gasi chimapanga mbali yaikulu ya m'mlengalenga (78.03% ya okwana). Ngakhale kuti asafe ndipo siligwirizana kuyaka Koma ndi inert, kupatula milandu kumene ndi mkangano kuti kutentha kwambiri, zomwe chikugwirizana ndi ena zitsulo achangu monga lifiyamu, magnesium. Choncho, nitrides pawiri anapanga. Komanso akhoza kutani ndi mpweya, chifukwa mu mapangidwe oxides asafe ndi asafe pamodzi ndi wa hydrogen pamaso pa catalysts - ammonia.

Kukonzekera asafe zinthu mafakitale
Asafe ndi mpweya njira yomweyo - mpweya yozungulira. Mu Laboratories ndi tinasonkhanitsa pa kuwonongeka zimene nitrite ammonium. Zimenezi ndi exothermic. Ndicho chifukwa ndi mmene zimakhalira amasulidwe 80 kcal (335 KJ) mphamvu. Pamafunika yozizira chotengera pamene Kutentha chofunika kuyambitsa zimene kubala asafe. Komanso, asafe maselo makampani akamagwira fractional distillation a m'mlengalenga madzi mpweya. Munthu angathe kupeza njira imeneyi monga "asafe mumlengalenga." njira yonse kupyola zomwe kufunafuna asafe amalandira ndi otetezeka ndi oyera mankhwala kwa mafakitale, mankhwala ndi banja mankhwala
Impact thanzi la munthu
Ngakhale madzi asafe ndi inert ndipo si poizoni, izo kungakhale ndi suffocation anthu, momwe iwo angakhoze aithamangitse mpweya mu mpweya m'munsimu mlingo zofunika pa moyo. Inhalation wa asafe mu yambiri zingachititse chizungulire, nseru, kusanza, imfa ya chikumbumtima ndi imfa. Imfa chifukwa cha imfa ya lathu ndi chikumbumtima, chimene chingalepheretse kudziletsa kupulumutsidwa ku madera zakhudzana. Pa ndende otsika mpweya, imfa ya chikumbumtima ndipo imfa kumachitika mu nkhani masekondi. Ogwira, kuphatikizapo ogwira ntchito yopulumutsa, asalowe malo opanda zida kudzikonda zili kupuma kapena makina, ngati mpweya ndende pansipa 19,5%.
Ngati asafe, ndiye amasungidwa muli wapadera. Izi ndi zofunika pofuna kuteteza ena ku mavuto mogwirizana ndi mchitidwe wa. Madzi asafe ndi kusungidwa pa mavuto mpaka 350 MPa mu chidebe buku la ku malita 80 450.

Madzi asafe - yosungirako ndi ntchito
Kusunga ndi kugwiritsa ntchito mankhwala muyenera kokha mu zipinda ndi mpweya wabwino. Iwo mwamtheradi sangathe kusungidwa mu malo ndi akachita. Kukonzekera asafe zasayansi ndipo amafuna njira yapadera kwa yosungirako zake muli. muli Cryogenic zili ndi zipangizo wapadera mpumulo kuthamanga ndi kulamulira kuthamanga mkati. M'mikhalidwe wabwinobwino, ali bwino. Palibe zikuphatikizapo, kuchotsa kapena kuchita mogwirizana ina ndi chipangizo mpumulo kuthamanga. Sikutheka kuti asafe ndi zinachitika pa mbali mosadziteteza za thupi.
Muli imene kusungidwa madzi asafe ayenera kugwiritsidwa ntchito ndi kusungidwa mu malo woongoka. Musati kutaya muli, kapena kuzisunga mbali. Inu simungakhoze paokha kutaya Mbale munali thunthu. Ngati muli ndi vuto mu ntchito za chidebe kapena vavu, ndiye kusiya ntchito yomweyo.

zida Personal zoteteza (PPE)
Muyenera ndithudi kuwerenga chitetezo ndi katundu wa asafe pamaso ntchito. M'pofunika kuteteza maso ndi gawo yovuta kwambiri kwa thupi kuchokera nthunzi ya madzi cryogenic. Kukonzekera kwa asafe mu m'galasi ndi ntchito zake kumapereka lingaliro PPE. Ayenera kukhala: a nkhope chishango kapena Goggles, kumasunga koyenera magolovesi chikopa, malaya aatali mikono ndi kabudula popanda cuffs, amafunika nsapato chitetezo makamaka kwa anthu amene kubala chidebe akuchitira. dongosolo kupuma tisatongwa kutetezedwa ndi masks wapadera.
