摘要:首先介绍了Ti(IV)水解的过程,在此基础上运用静电吸引及静电中和理论对水合钛离子(偏钛酸)包膜空心玻璃微珠的的机理进行了探讨。通过所建立的模型对其包膜机理进行了较合理的解释。因水合钛离子带正电,空心玻璃微珠带负电,在水解及沉积的过程中两者可通过静电吸引而包膜。当静电荷被中和完毕后,则是分子间的范德华力起主要作用。当包膜的厚度超过5层后,则范德华力已经很微弱,即已无法继续包膜,包膜过程随即结束。

Abstract: The hydrolysis of Ti (IV) and the process of the formation ofelectriferous hydrate titanium ion (ETHl) are intrduced. Based on theanalysis of the hydrolysis process, through the theory of the electrostaticattraction and electric charge neutralization, an explaination about themechanism of enwrapping hollow tiny glass particles (HTCP) with EHTI isprovided. During the enwrapping process, for EHTI have positive charges.and HTCP have negetive charges, these two will neutratlize each other un-til their charges are used up, then came to the turn of Van der Waals in-teraction. When the mumber of the layer has exceeds 5,the Van der Waalsinteraction become so faint that the enwrapping process can not be contin-ued
