Lisebelisoa tse sa tšoaneng tse tala ho ea ka karolo ea tsona ea ho roala li-electrode li ka aroloa ka:
(1) Arc stabilizer
Mosebetsi o ka sehloohong ke ho etsa hore electrode e be bonolo ho qala arc le ho boloka mollo o tsitsitseng oa arc ts'ebetsong ea welding.Joalo ka lisebelisoa tse tala tsa arc stabilizer ke tse ling tse nang le palo e itseng ea lisebelisoa tse tlase tsa ionization tse ka bang bonolo, joalo ka feldspar, sodium silicate, rutile, titanium dioxide, marble, mica, ilmenite, ilmenite e fokotsehileng joalo-joalo.
(2) Setsi sa ho etsa khase
Tlas'a ketso ea mocheso o phahameng oa arc decomposition khase, ho etsa sepakapaka se sireletsang, ho sireletsa arc le tšepe e qhibilihisitsoeng, ho thibela ho kenella ha oksijene le naetrojene moeeng o potolohileng.Lintho tse sebelisoang ka tloaelo ho etsa khase ke carbonate (e kang marble, dolomite, rhombic acid, barium carbonate, joalo-joalo) le lintho tse phelang (tse kang phofo ea lehong, starch, cellulose, resin, joalo-joalo).
(3) Deoxidizer (eo hape e tsejoang e le moemeli oa ho fokotsa)
Likahare tsa oksijene ka tšepe ea weld li ka fokotsoa mme ts'ebetso ea tšepe ea weld e ka ntlafatsoa ka karabelo ea lik'hemik'hale ea metallurgic ts'ebetsong ea welding.Deoxidizer haholo-holo e na le likarolo tsa motsoako oa tšepe le phofo ea tšepe e amanang haholo le oksijene.Deoxidizer e sebelisoang hangata ke ferromanganese, ferrosilicon, ferrotitanium, ferroaluminum, silicon calcium alloy, joalo-joalo.
(4) Plasticizer
Mosebetsi oa eona o ka sehloohong ke ho ntlafatsa polasetiki, elasticity le fluidity ha ho ntse ho hatelloa li-electrode coating , ho ntlafatsa boleng ba ho roala ha electrode, e le hore sebaka se boreleli sa ho roala ha electrode se se ke sa phunyeha.Hangata, khetha elasticity e itseng, e thellang kapa e monyang ka mor'a litšobotsi tse itseng tsa katoloso ea thepa, joalo ka mica, seretse se tšoeu, titanium dioxide, talc, khalase ea metsi e tiileng, selulose, joalo-joalo.
(5) Moemeli oa motsoako
E sebelisetsoa ho lefella ho chesoa ha likarolo tsa alloying ts'ebetsong ea ho cheselletsa le ho fetisetsa lisebelisoa tsa alloying ho weld, e le ho etsa bonnete ba hore lik'hemik'hale le thepa ea tšepe ea weld.Ho ea ka tlhoko ea ho khetha mefuta e fapaneng ea li-ferroalloys (tse kang ferromanganese, ferrosilicon, ferrochrome, tšepe le tšepe, ferric vanadium, ferric niobium, ferric boron, ferrosilicon e sa tloaelehang ea lefatše, joalo-joalo) kapa tšepe e hloekileng (joalo ka tšepe ea manganese, tšepe ea chromium). , phofshoana ea nickel, phofo ea tungsten, joalo-joalo).
(6) Moemeli oa ho etsa li-slag
Ho tjheseletsa ho ka theha thepa e itseng ea 'mele le ea lik'hemik'hale ea slag e qhibilihisitsoeng, sireletsa lerotholi la welding le tšepe e qhibilihisitsoeng ea letamo, ho ntlafatsa sebopeho sa weld, joalo ka ha moemeli oa slagging oa lisebelisoa tse tala ke marble, fluorite, dolomite, magnesia, feldspar, seretse se tšoeu, mica, quartz. , rutile, titanium dioxide, ilmenite, joalo-joalo.
(7) Setlamo
Thepa ea ho roala e tlamahane ka thata ho setsi sa welding, 'me seaparo sa electrode se na le matla a itseng ka mor'a ho omisa.Ts'ebetsong ea ho cheselletsa metallurgy, ha ho na phello e kotsi ho letamo la weld le tšepe ea weld.Li-binders tse sebelisoang hangata ke sodium silicate (potasiamo, sodium le silicate e tsoakiloeng ea sodium) le phenolic resin, gum, joalo-joalo.
