| 硅溶胶属胶体溶液，无臭、无毒，分子式可表示为 mSiO2nH2O. Silica sol is a colloidal solution, odorless and non-toxic. Its molecular formula can be expressed as mSiO 2 nH 2. 1.由于胶体粒子微细(10 - 20nm)，有相当大的比表面积，粒子本身无色透明，不影响被覆盖物的本色。 1. Because the colloidal particles are very fine (10-20 nm) and have considerable specific surface area, the particles themselves are colorless and transparent, which does not affect the nature of the covered material. 2. 粘度较低，水能渗透的地方都能渗透，因此和其它物质混合时分散性和渗透性都非常好。 2. Viscosity is low, where water can penetrate, so when mixed with other substances, dispersion and permeability are very good. 3. 当硅溶胶水份蒸发时，胶体粒子牢固地附着在物体表面，粒子间形成硅氧结合，是很好的粘合剂。 3. When the silica sol evaporates, the colloidal particles firmly adhere to the surface of the object, forming silica-oxygen bonding between the particles, which is a good adhesive. |
