【摘要】：目的研究異抗壞血酸鈉、六偏磷酸鈉、D-葡萄糖酸鈉和硫酸鋅的復(fù)配物在軟化水水質(zhì)中對(duì)碳鋼腐蝕率的影響。方法通過靜態(tài)掛片和旋轉(zhuǎn)掛片實(shí)驗(yàn),研究不同濃度、pH值、溫度等條件下,復(fù)合緩蝕劑對(duì)碳鋼腐蝕率的影響,對(duì)腐蝕機(jī)理進(jìn)行探討。結(jié)果在軟化水pH=10,緩蝕劑質(zhì)量濃度為150 mg/L,溫度為50℃的條件下,復(fù)合緩蝕劑對(duì)碳鋼有較好的緩蝕效果,靜態(tài)掛片實(shí)驗(yàn)中碳鋼的腐蝕率為0.0303mm/a,緩蝕率為86.31%;旋轉(zhuǎn)掛片實(shí)驗(yàn)中碳鋼的腐蝕率為0.0350 mm/a,緩蝕率為96.12%。結(jié)論在軟化水水質(zhì)中,碳鋼的腐蝕率隨著復(fù)合緩蝕劑投藥量、溶液pH值的增大而降低,隨著溫度的升高而增大。
[Abstract]:Objective to study the effect of sodium isoascorbate, sodium hexametaphosphate, sodium D-gluconate and zinc sulfate on the corrosion rate of carbon steel in soft water. Methods the influence of composite corrosion inhibitor on corrosion rate of carbon steel under different concentration, pH value and temperature was studied by static and rotating hanging sheet experiments, and the corrosion mechanism was discussed. Results when the concentration of pH=10, inhibitor in soft water was 150 mg/L, and the temperature was 50 鈩，
