Answer
Haɗaɗɗen hydrogen yana faruwa ne lokacin da hydrogen ɗin atomic ya shiga ramin ƙarfe na kristal na carbon (yawanci manyan ƙarfe na bazara irin su SAE 1070-1090) yayin sarrafa lantarki, ɗaukar acid, ko a cikin yanayin aiki mai lalata sosai.
Makaniyanci:
Atom ɗin hydrogen suna yaɗuwa kuma suna taruwa a wuraren da ke da yawan damuwa, ƙananan ɓoyayyiya, ko ɓarna. Lokacin da aka ɗora ruwan bazara a ƙarƙashin damuwa, waɗannan aljihunan atomic sun sake haɗuwa cikin kwayoyin iskar hydrogen ($ H_2 $), suna haifar da matsananciyar iskar gas na ciki wanda ke fara fashewar micro-cracking kuma yana haifar da gazawar tsarin nan da nan, gaggautsa, bala'i mai fa'ida a ƙarƙashin ƙarancin ƙira.
Ƙarfafawa da Ka'idojin Kariya:
1. A guji Tsabtace Acid: Yi amfani da gogewar injin ko share alkaline maimakon hydrochloric ko sulfuric acid baho.
2. Yin burodi (Wajibi): A cikin sa'a 1 (mafi girman 4 hours) na electroplating (misali, zinc ko cadmium), maɓuɓɓugan ruwa dole ne su sha yin burodin taimako na damuwa a $375^\circ F \ rubutu zuwa } 400^ \ circ F $ ($ 190 ^ C \ Rubutun {zuwa } 205 ^ \ Circ C $ 4 zuwa 2 mafi ƙarancin sa'o'i 205 ^ circ C $ 4 zuwa 2 F. (ASTM B850).
3. Tagar yin burodi: Yin burodi da aka jinkirta bayan sanyawa lantarki yana ba da hydrogen damar zama na dindindin, yana sa yin burodi ba ya da tasiri.
