| 中文摘要 | The microencapsulation technology was brought in to solidify corrosion inhibitor in order to prolong the releasing time of it. In this work, thiourea (H(2)NCSNH(2)) was used as a corrosion inhibitor and microcapsuled using glutin and polyvinyl alcohol (PVA), respectively, as protective agent. The re-sealing process was used as a way to prolong the releasing time of the H(2)NCSNH(2) encapsulated in microcapsules. It was found that the H(2)NCSNH(2) microcapsule corrosion inhibitor using PVA as a protective agent had a better releasing time. The releasing times of the H(2)NCSNH(2) microcapsule corrosion inhibitors were prolonged from 18 to 48 h by re-sealing process and using PVA as a protective agent. Both the use of PVA as a protective agent and the application of the re-sealing process decreased the encapsulation efficiency of the H(2)NCSNH(2). The performance parameters on protecting Q235 carbon steel from corrosion in 0.1-M H(2)SO(4) solution were evaluated by polarization curve and electrochemical impedance spectra methods. The results showed that the H(2)NCSNH(2) released into the solution from microcapsules could well protect Q235 carbon steel from corrosion and the corrosion-inhibiting mechanisms of it were the same as that of H(2)NCSNH(2). |
