Application: Hydrophobic nano silica is a type of nanomaterial with hydrophobic properties. After surface modification, it can form a stable dispersion system in water. 1. Hydrophobicity: Hydrophobic nano silica has high hydrophobicity and can spontaneously form micelle structures in water, forming dispersed systems. This characteristic enables it to play a role in dispersion, wetting, and enhancing transparency in some applications. 2. High specific surface area: Nano silica has a large specific surface area, which can provide more active surface sites and has strong adsorption capacity. It can be used to adsorb organic matter, metal ions, etc., in environmental treatment and wastewater treatment It has a wide range of applications in various fields. 3. Heat resistance: Hydrophobic nano silica has a certain degree of heat resistance and can stably exist under high temperature conditions. There are two main methods for preparing hydrophobic nano silica: physical modification and chemical modification. Physical modification usually includes sol gel method, high temperature melting method and so on. Hydrophobicity is achieved by changing the surface structure and size. Chemical modification mainly includes silane coupling agent method, surface modification method, etc., which changes its surface properties through chemical reactions with organic or other compounds.

When using hydrophobic nano silica, the following safety information should be noted: 1. Hydrophobic nano silica powder has a large specific surface area and should be avoided from being inhaled into the air. If it is necessary to operate nano silica in powder form, protective measures should be taken, such as wearing a mask. 2. During the preparation and use of nano silica, it is important to avoid prolonged contact with the skin and eyes to prevent allergic reactions or other discomforts.
