kuwotcherera elekitirodi 2% cerium WC20 cerium tungsten elekitirodi

chowotcherera elekitirodi 2% cerium WC20 cerium tungsten elekitirodi Chithunzi Chowonetsedwa

Kufotokozera Kwachidule:

Ma elekitirodi a Cerium tungsten amagwiritsidwa ntchito kwambiri pakuwotcherera kwa TIG chifukwa amagwira ntchito bwino pakuwotcherera kwa AC ndi DC. Amadziwika ndi kukhazikika kwawo kwa arc, mawonekedwe abwino oyatsira, komanso magwiridwe antchito osasinthasintha, kuwapangitsa kukhala oyenera zida zoonda komanso zowotcherera zovuta.

Kodi tungsten ndi 2% Ceria ndi mtundu wanji?

Tungsten imaphatikizidwa ndi 2% ceria kupanga tungsten-cerium oxide kompositi yomwe nthawi zambiri imagwiritsidwa ntchito ngati njira yosagwirizana ndi ma radiation ya thoriated tungsten maelekitirodi pakuwotcherera.

Mtundu wa tungsten wokhala ndi 2% ceria ukhoza kusiyana koma nthawi zambiri umakhala wotuwa kapena wotuwa. Mthunzi weniweni ukhoza kudalira zinthu monga kupanga mapangidwe ndi zokutira zowonjezera kapena mankhwala omwe amagwiritsidwa ntchito pazinthuzo.

Kodi pali kusiyana kotani pakati pa Thoriated ndi Ceriated tungsten?

Thoriated tungsten ndi cerium tungsten onse ndi ma elekitirodi a tungsten owotcherera, koma ali ndi nyimbo ndi zinthu zosiyanasiyana:

1. Thoriated tungsten:
-Ma elekitirodi a tungsten opangidwa ndi thoriated amakhala ndi thorium oxide pang'ono (nthawi zambiri pafupifupi 1-2%). Kuwonjezera kwa thorium kumapangitsa kuti ma elekitironi atulutse ma elekitirodi, kuti zikhale zosavuta kuyambitsa ndi kusunga arc yowotcherera.
-Thoriated tungsten imadziwika ndi kunyamula kwake kwakukulu, kukhazikika kwa arc komanso moyo wautali. Amagwiritsidwa ntchito kwambiri pakuwotcherera kwa DC, makamaka pazowotcherera monga chitsulo cha carbon, chitsulo chosapanga dzimbiri, ma aloyi a nickel ndi titaniyamu.

2. Tungsten cerium:
- Ma electrode a Cerium tungsten ali ndi cerium oxide ngati chinthu chothandizira. Nyimbo zambiri za cerium tungsten zimakhala ndi 1.5-2% ya cerium oxide.
- Cerium tungsten ili ndi chiyambi chabwino komanso chokhazikika, makamaka pamawotchi ocheperako. Ndi oyenera kuwotcherera AC ndi DC choncho oyenera zipangizo zosiyanasiyana ndi njira kuwotcherera.
- Cerium tungsten nthawi zambiri imasankhidwa ngati njira yopanda ma radiation ku thorium tungsten kuti athetse nkhawa zokhudzana ndi zoopsa za thanzi zomwe zimagwirizanitsidwa ndi kukhudzidwa kwa anthu.

Mwachidule, pamene ma elekitirodi a thoriated tungsten ndi ma elekitirodi a cerium tungsten amagwiritsidwa ntchito powotcherera, ali ndi nyimbo zosiyanasiyana ndipo ndi oyenera kugwiritsa ntchito kuwotcherera ndi mikhalidwe yosiyanasiyana. Thoriated tungsten imadziwika ndi kunyamula kwake kwanthawi yayitali ndipo imagwiritsidwa ntchito nthawi zambiri pakuwotcherera kwa DC, pomwe cerium tungsten ili ndi poyambira komanso kukhazikika kwa arc ndipo ndiyoyenera kuwotcherera AC ndi DC.

Kodi 2% thoriated tungsten radioactive?

Inde, 2% thoriated tungsten maelekitirodi amatengedwa ngati radioactive pang'ono chifukwa cha kupezeka kwa thorium okusayidi mu ma elekitirodi kapangidwe. Thorium ndi chinthu chomwe chimapezeka mwachilengedwe mu ma elekitirodi a tungsten omwe amatulutsa tinthu tating'ono ta alpha. Ngakhale milingo ya radioactivity ndi yocheperako, ndikofunikira kuti mugwire bwino ndikutaya ma electrode a thoriated tungsten kuti muchepetse kuwonekera.

Chifukwa cha radioactive chikhalidwe cha thorium, kugwiritsa ntchito, kusamalira ndi kutaya thorium tungsten electrode amafuna chitetezo ndi malamulo malamulo. Zotsatira zake, pali kusintha kwa njira zina zosagwiritsa ntchito ma radio monga tungsten cerium, tungsten lanthanate kapena zinthu zina zapadziko lapansi zomwe sizipezeka ndi doped tungsten maelekitirodi, makamaka m'mafakitale omwe chitetezo cha ogwira ntchito ndi kukhudzidwa kwa chilengedwe ndikofunikira.
