摘要
The corrosive rates of 4 types of metals as well as epoxy-coated metal in a variety of preservatives derived from different copper sources and ingredients were measured in this paper.The main results show that:CCA is less corrosive to red brass and Q235A steel than other copper formulations;Copper-based preservatives such as ACQ and CuAz derived from basic cupric carbonate or cupric hydroxide are much less corrosive to Q235A steel than those from cupric sulfate;Ethanolamine is less corrosive to Q235A steel than ammonia in ACQ derived from cupric hydroxide,while other ingredients are the same;Epoxy resin coating could be used for protecting red brass,Q235A steel and zinc hot-dipped galvanized mild steel from corrosion.
The corrosive rates of 4 types of metals as well as epoxy-coated metal in a variety of preservatives derived from different copper sources and ingredients were .measured in this paper. The main results show that： CCA is less corrosive to red brass and Q235A steel than other copper formulations; Copper-based preservatives such as ACQ and CuAz derived from basic cupric carbonate or cupric hydroxide are much less corrosive to Q235A steel than those from cupric sulfate; Ethanolamine is less corrosive to Q235A steel than ammonia in ACQ derived from cupric hydroxide, while other ingredients are the same; Epoxy resin coating could be used for protecting red brass, Q235A steel and zinc hotdipped galvanized mild steel from corrosion.
