Nguwuphi umbala we-tungsten ene-2% yeCeria?

I-Tungsten idityaniswe ne-2% ye-ceria ukuze yenze i-tungsten-cerium oxide composite ehlala isetyenziswa njenge-non-radioactive alternative kwi-thoriated tungsten electrode kwi-welding applications.

Umbala we-tungsten oqulethe i-2% ye-ceria unokwahluka kodwa udla ngokuba ngwevu okanye ungekho mhlophe. Umthunzi othile unokuxhomekeka kwizinto ezifana nenkqubo yokuvelisa kunye naluphi na iingubo ezongezelelweyo okanye unyango olusetyenziswe kwizinto eziphathekayo.

Uthini umahluko phakathi kweTungsten yeThoriated kunye neCeriated?

I-Thoriated tungsten kunye ne-cerium tungsten zombini zi-electrode ze-tungsten zokuwelda, kodwa zineendlela ezahlukeneyo zokuqamba kunye neempawu:

1.Itungsten ethotyiweyo:
-I-electrodes ye-tungsten ene-thoriated iqulethe ixabiso elincinci le-thorium oxide (ngokuqhelekileyo malunga ne-1-2%). Ukongezwa kwe-thorium kuphucula iimpawu zokukhutshwa kwe-electron ye-electrode, okwenza kube lula ukuqala nokugcina i-arc welding.
-I-tungsten ethotyiweyo iyaziwa ngokuthwala kwayo okuphezulu ngoku, uzinzo oluhle lwe-arc kunye nobomi obude. Iqhele ukusetyenziswa kwizicelo ze-welding ze-DC, ngakumbi kwizinto zokuwelda ezifana nentsimbi ye-carbon, insimbi engenasici, i-alloys ye-nickel kunye ne-titanium.

2. I-Tungsten cerium:
- I-electrode ye-cerium tungsten iqulethe i-cerium oxide njenge-alloying element. Iingqungquthela ze-cerium tungsten eziqhelekileyo ziqulethe i-1.5-2% ye-cerium oxide.
- I-cerium tungsten ine-arc entle yokuqala kunye nokuzinza, ngakumbi kwizicelo eziphantsi ze-welding zangoku. Ifanelekile kwi-AC kunye ne-DC welding kwaye ngoko ifanelekile kwizinto ezahlukeneyo kunye neenkqubo ze-welding.
- I-Cerium tungsten isoloko ikhethwa njengenye indlela engeyiyo i-radioactive kwi-thorium tungsten ukujongana neenkxalabo malunga neengozi zempilo ezinokuthi zidibanise ne-thorium exposure.

Isishwankathelo, ngelixa zombini ii-electrode ze-tungsten ezithotyiweyo kunye ne-cerium tungsten electrode zisetyenziselwa i-welding, zinemixholo eyahlukeneyo kwaye zifanelekile kwizicelo ezahlukeneyo kunye neemeko. I-Thoriated tungsten iyaziwa ngokuthwala kwayo ngoku okuphezulu kwaye isoloko isetyenziswa kwi-DC welding, ngelixa i-cerium tungsten ine-arc entle yokuqala kunye nozinzo kwaye ilungele zombini i-AC kunye ne-DC welding.

Ngaba i-2% thoriated tungsten radioactive?

Ewe, i-2% ye-thoriated tungsten electrode ithathwa njenge-radioactive kancinane ngenxa yobukho be-thorium oxide ekubunjweni kwe-electrode. Ithorium yinto eyenzeka ngokwemvelo yeradioactive element efumaneka kwi-tungsten electrode ekhupha amasuntswana e-alpha asezantsi. Nangona amanqanaba e-radioactivity esezantsi kakhulu, kusabalulekile ukuphatha ngokufanelekileyo kwaye ulahle i-thoriated tungsten electrode ukunciphisa utyhileko olunokwenzeka.

Ngenxa yobume be-radioactive ye-thorium, ukusetyenziswa, ukuphatha kunye nokulahlwa kwe-thorium tungsten electrodes kufuna ukuqwalaselwa kokhuseleko kunye nokulawula. Ngenxa yoko, kukho utshintsho olubhekiselele kwezinye iindlela ezingezo-radioactive ezifana ne-tungsten cerium, i-tungsten lanthanate okanye ezinye izinto ezinqabileyo zomhlaba ezine-doped tungsten electrode, ngakumbi kumashishini apho ukhuseleko lwabasebenzi kunye neenkxalabo zokusingqongileyo zibaluleke kakhulu.
