Momwe mungapewere kuwonongeka kwa ma radiation mu argon arc welding?
- Magwero ndi zoopsa za radiation
The thorium tungsten elekitirodi ntchito argon arc kuwotcherera ndi plasma arc kuwotcherera ali 1-1.2% thorium okusayidi, amene ndi radioactive mankhwala amene amakhudzidwa ndi ma radiation pa kuwotcherera ndi kukhudzana ndi thorium tungsten ndodo.
Radiation imagwira ntchito pa thupi la munthu m'njira ziwiri: kuwala kwakunja ndi kuwala kwamkati kudzera mu kupuma ndi kugaya chakudya. Kafukufuku wambiri ndi kuyeza pa kuwotcherera kwa argon arc ndi kuwotcherera kwa plasma arc kwawonetsa kuti zoopsa zawo za radioactive ndizochepa, chifukwa kumwa kwa tsiku ndi tsiku kwa thorium tungsten electrode ndi ma milligrams 100-200 okha, okhala ndi ma radiation otsika kwambiri komanso osakhudzidwa pang'ono. thupi la munthu.
Koma pali zinthu ziwiri zomwe ziyenera kuzindikirika:
Nkhani imodzi ndi mpweya woipa wowotcherera mkati mwa chidebecho, ndipo tinthu tating'onoting'ono ta radioactive mu utsi titha kupitirira ukhondo;
Kachiwiri, popera ndodo za thorium tungsten komanso m'malo omwe pali ndodo za thorium tungsten, kuchuluka kwa ma radioactive aerosols ndi fumbi kumatha kufikira kapena kupitilira miyezo yaukhondo.
Ma radioactive zinthu kuukira thupi kungayambitse matenda opatsirana, makamaka kuwonetseredwa mu kufooka ambiri zinchito udindo, zoonekeratu kufooka ndi kufooka, kwambiri yafupika kukana matenda opatsirana, kuwonda ndi zizindikiro zina.
- Njira zopewera kuwonongeka kwa ma radiation
1) Ndodo za thorium tungsten ziyenera kukhala ndi zida zosungirako zodzipereka, ndipo zikasungidwa mochuluka, ziyenera kubisika m'mabokosi achitsulo ndikuyika ndi mapaipi otulutsa mpweya.
- Mukamagwiritsa ntchito chivundikiro chotsekedwa chowotcherera, chophimbacho sichiyenera kutsegulidwa panthawi ya ntchito. Mukamagwira ntchito pamanja, ndikofunikira kuvala chisoti choteteza kapena kuchita zinthu zina zothandiza.
- Mawilo apadera akupera ayenera kukonzekera pogaya ndodo za thorium tungsten. Makina opukutira amayenera kukhala ndi zida zochotsa fumbi. Zinyalala zogaya pansi pa makina opangira gudumu ziyenera kunyowa nthawi zonse ndikutsukidwa mozama.
- Pogaya ndodo za thorium tungsten, masks a fumbi ayenera kuvala. Pambuyo pokhudzana ndi ndodo za thorium tungsten, manja ayenera kutsukidwa ndi madzi oyenda ndi sopo, ndipo zovala zogwirira ntchito ndi magolovesi ziyenera kutsukidwa nthawi zonse.
5) Mukawotcherera ndi kudula, sankhani zofunikira kuti mupewe kuwotcha kwambiri ndodo za thorium tungsten.
