摘要
采用油相分离的方法对水溶性亚硝酸钠进行微胶囊化,然后利用锐孔—凝固浴的方法以海藻酸钙作为囊壁进行再包封制备亚硝酸钠微胶囊.测试了亚硝酸钠微胶囊的缓释性能,并使用极化曲线和电化学阻抗法对亚硝酸钠微胶囊缓蚀剂性能进行了评价.
NaNO2 was sealed firstey by thermal phase separation method, and then the microcapsule was sealed again by organic solvent evaporation method. The release probobility of NaNO2 microcapsule inhibitor was evaluated in this paper. And the inhibition performance of NANO2 microcapsule inhibitor was evaluated by using polarization curve and electrochemical impedance spectroscopy.
