功能性水制造装置
1
《技术与市场》 2002年第8期24-25,共2页
功能性水也称强酸化水、超酸化水或强碱性水等,它是利用水在电磁处理下,可以发生电解的原理制成的。电解时,将容器的两特殊电极之间用特殊隔膜分开,分别在阳极和阴极会产生强酸化水和强碱性水。

The influences of different alkaline conditions on the kinds and morphologies of steel slag's hydration products, Ca(OH)2 con- tent of hydration products, pore stiucture of hardened paste, non-evaporable water content of hydration products, and strength of steel slag mortar were investigated by changing the initial alkalinity of the hydration condition of steel slag. The results showed that increasing the initial alkalinity of hydration condition can promote the early hydration of steel slag's active com- ponents (e,g., C2S, C3S, and C12A7), but it has little influence on their late-age hydration degree. The hydration degree of non-active components (e.g., RO phase and Fe304) of steel slag is very low even under strong alkaline condition with pH value of 13.8. The excitation effect of alkaline condition on the early hydration of steel slag is more obvious with the increase of pH value, but the kinds of steel slag's hydration products are not influenced by changing the alkaline condition. The amount of steel slag's hydration products is limited, so the strength of alkali-activated steel slag mortar is very low though the strong al- kaline condition significantly promotes the early hydration of steel slag. Steel slag is not an ideal raw material for alka- li-activated cementitious material. 展开更多

The mechanism of the conversion of titanate nanotubes into nanoribbons is of considerable interest.The details of the transformation processes involved when nanoribbons are produced from a P25 TiO 2 powder precursor by alkaline hydrothermal treatment have been investigated systematically by transmission electron microscopy.A multistep attachment model is proposed for the growth at the early stage of coarsening.The treatment duration has a strong effect on the change in product morphology from hollow nanotubes into nanoribbons,since the nanotubes cannot retain their morphology in the strong alkaline solution for extended periods of time.Most of the nanotubes were etched and dissolved,providing the nutrients for subsequent nanoribbon growth.Some stable nanotubes grew spirally internally to form nanowires or became connected together to form rafts which acted as the grains for nanoribbon growth.With increasing hydrothermal time,a large number of nanotubes and other fragments became attached to the grains which began to grow larger and eventually formed the nanoribbons,in a process in which the stepped faces and kinked faces became fused and were eliminated while the flat faces were retained in the nanoribbon morphology. 展开更多
