由一个铝核心和 SiO 2 和 polyacrylic 酸的壳组成的双层铝被综合。这修改的铝被用来在水运的媒介改进腐蚀抵抗和铝的散性质。TEM, FTIR, XPS,和 EDX 决心证明泛美航空公司和 SiO 2 在铝的表面上是涂的。发展的氢察觉证明合成粒子的腐蚀抵抗显著地被改进了。SiO 2 的最大的腐蚀抑制效率涂的铝(当时, SiO 2@Al) 是 95.1% 双层的涂的铝(PAA/SiO 2@Al) 是 98.8% 。同时, polyacrylic 酸层显著地改进了铝的凝块。根据可分散性测试, 50% 体积部分的粒子尺寸[d (0.5 )] 铝, SiO 2@Al 和 PAA/SiO, 2@Al 分别地是 42, 53,和 34 m。
A double-layer aluminum consisting of an aluminum core and a shellof SiO2 and polyacrylic acid was synthesized.This modified aluminum was used to improve the corrosion resistance and dispersive property of aluminum in waterborne media.TEM,FTIR,XPS,and EDX determination showed that PAA and SiO2 were coated on the surface of aluminum.Evolved hydrogen detection showed that the corrosion resistance of composite particle had been markedly improved.Maximum corrosion inhibition efficiency of SiO2 coated aluminum(SiO2@Al)was 95.1% while that of double-layer coated aluminum(PAA/SiO2@Al)was 98.8%.Meanwhile,polyacrylic acid layer improved the agglomeration of aluminum significantly.According to the dispersibility test,the particle size of 50% volume fraction [d(0.5)] of aluminum,SiO2@Aland PAA/SiO2@Alwere 42,53,and 34 μm,respectively.
