E347-16
Electrode-ka birta ah ee birta ah waxa loo qaybin karaa chromium ahama birta electrode iyo chromium nikkel steel electrode, labadan nooc ee electrodes si waafaqsan heerka qaranka, waa waafaqsan GB/T983 -1995 qiimaynta.Chromium ahama waxay leedahay iska caabin daxalka qaarkood (oxidizing acid, organic acid, cavitation) caabbinta kulaylka iyo iska caabinta daxalka.Inta badan waxaa loo doortaa agabka xarunta korontada, warshadaha kiimikada, batroolka iyo wixii la mid ah.Laakiin birta chromium guud ahaan weldability liidata, waa in fiiro gaar ah u habka alxanka, xaaladaha daaweynta kulaylka iyo doorashada ee electrode habboon.Chromium-nickel ahama electrode leeyahay iska caabin daxalka wanaagsan iyo oxidation iska caabin ah, oo si ballaaran loo isticmaalo warshadaha kiimikada, bacriminta, batroolka, wax soo saarka mashiinada caafimaadka.Si looga hortago daxalka u dhexeeya indhaha sababtoo ah kululaynta, alxanka hadda waa in aanu noqon mid aad u weyn, ka yar carbon steel electrode ku saabsan 20% , arc waa in aanay noqon mid aad u dheer, qaboojinta degdeg ah u dhexeeya lakabyada, si ay u cidhiidhi kuul waa ku haboon.
