The coating inobata basa muzvakaoma metallurgical reactions uye kuchinja kwemuviri nemakemikari panguva yekugadzira, kunyanya kukunda matambudziko emagetsi emagetsi panguva yekuputika, saka kupfekedza zvakare chimwe chezvinhu zvikuru zvinotarisa kunaka kwesimbi weld.
Electrode coating: inoreva rukuvhute rwakapfekedzwa zvakafanana pamusoro peiyo welding core nekubatanidza zvinhu zvakatsetseka-grained zvine hunhu hwakasiyana hwemuviri nemakemikari.
Basa reiyo electrode coating: kugadzira slag ine yakakodzera yemuviri uye makemikari zvimiro senge melting point, viscosity, density, uye alkalinity panguva yewelding process, kuve nechokwadi chekugadzikana kwearc kupisa, kuita kuti droplet simbi iite nyore kushandura, uye kuve. yakatenderedza arc zone uye dziva rakanyungudutswa Gadzira mamiriro ekunze ekudzivirira nzvimbo yewelding, uye uwane yakanaka weld chimiro uye kuita.
Izvo zvakare zvinogoneka kuwedzera deoxidizers, alloying zvinhu kana imwe chiyero chesimbi poda kune yekupfekedza kuti isangane nezvinodiwa zve weld metal performance kana kuvandudza deposition performance.
Xinfa welding zvinhu zvine mhando yakanaka, ndapota tarisa kune ruzivo:https://www.xinfatools.com/welding-material/

Zvigadzirwa zvakasiyana-siyana zvinogona kugoverwa mu:
(1) arc stabilizer
Basa guru nderekuita kuti electrode ive nyore kurova arc uye kuchengeta arc ichipfuta zvakatsiga panguva yewelding process. Izvo zvigadzirwa zvinoshandiswa searc stabilizers zvinonyanya zvinhu zvine huwandu hwezvinhu zviri nyore ionized zvine yakaderera ionization kugona, senge feldspar, girazi remvura, rutile, titanium dioxide, marble, mica, ilmenite, yakaderedzwa ilmenite, nezvimwe.
(2) Gasi generating agent
Iyo gasi yakasvibiswa pasi pekushisa kwepamusoro kwearc, kuumba mhepo inodzivirira, kuchengetedza arc uye yakanyungudutswa dziva simbi, uye kudzivirira kupindira kweokisijeni uye nitrogen mumhepo yakapoteredza. Inowanzo shandiswa gasi-inogadzira zvinhu ndeye carbonates (yakadai semarble, dolomite, magnesite, barium carbonate, nezvimwewo) uye organic zvinhu (zvakadai sehupfu hwehuni, starch, cellulose, resin, nezvimwewo).
(3) Deoxidizer (inozivikanwawo seanoderedza mumiririri)
Kuburikidza nekemikari metallurgical reaction muwelding process, iyo okisijeni yemukati muweld simbi inoderedzwa, uye kushanda kwesimbi weld kunovandudzwa. Deoxidizers anonyanya kuve maaloyi esimbi uye hupfu hwawo hwesimbi hune zvinhu zvine hushamwari hwepamusoro hweokisijeni. Zvinowanzoshandiswa deoxidizers zvinosanganisira ferromanganese, ferrosilicon, ferrotitanium, ferroaluminum, uye silicon-calcium alloys.
(4) Plasticizer
Basa guru nderekuvandudza mapurasitiki, elasticity uye fluidity yejasi rekuvhara mukati mekugadzirwa kwe electrode press coating, kuvandudza kunaka kwe electrode coating, uye kuita kuti pamusoro pe electrode coating iite nyore pasina kuputika. Kazhinji, zvinhu zvine kumwe elasticity, kutsvedza kana humwe hunhu hwekuwedzera mushure mekutora mvura zvinosarudzwa, senge mica, ivhu chena, titanium dioxide, talcum poda, girazi remvura yakasimba, cellulose, nezvimwe.
(5) alloying agent
Inoshandiswa kutsiva kupisa kwekurasikirwa kwezvinhu zvealloying panguva yewelding uye kushandura alloying zvinhu muweld kuti ive nechokwadi chekuumbwa kwemakemikari uye zvimiro zveweld simbi. Maferroalloys akasiyana-siyana (akadai seferromanganese, ferrosilicon, ferrochrome, simbi, ferrovanadium, ferroboron, isingawanzo pasi ferrosilicon, nezvimwewo) kana simbi dzakachena (sesimbi manganese, metal chromium, nickel powder, tungsten powder, nezvimwewo) inogona kusarudzwa maererano nezvinodiwa. kumirira).
(6) Slagging agent
Munguva yewelding, inogona kuumba slag ine zvimwe zvemuviri uye makemikari zvimiro, kudzivirira welding madonhwe uye yakanyungudutswa dziva simbi, uye kunatsiridza weld kuumbwa. Raw zvinhu zvinoshandiswa se slagging agents zvinosanganisira marble, fluorite, dolomite, magnesia, feldspar, chena Mud, mica, quartz, rutile, titanium dioxide, ilmenite, nezvimwe.
(7) Binder
Itai kuti zvinhu zvekuputira zvibatanidzwe zvakasimba kune welding core, uye ita kuti electrode coating ine rimwe simba mushure mekuoma. Haina kukanganisa padziva rakanyungudutswa uye weld simbi panguva welding metallurgy. Anowanzo shandiswa mabhanhire girazi remvura (potassium, sodium uye girazi ravo remvura rakasanganiswa), phenolic r
