Silicon dioxide miropowder,active - Introduction
Activated silica powder is a high surface area, porous inorganic material. It has the following properties:
1. High adsorption capacity: active silica powder can absorb many organic and inorganic substances, such as gas, water, dyes, etc.
2. High catalytic activity: Due to its high specific surface area and pore structure, active silica powder can be used as a catalyst to play a catalytic role in chemical reactions.
3. Good dispersibility: Active silica micropowder has good dispersibility and stability, and can be used to prepare highly dispersed liquid or solid materials.
Activated silica powder has a wide range of applications in many fields, including:
1. Adsorbent: can be used for wastewater treatment, air purification, gas separation, etc.
2. Catalyst: can be used in organic synthesis, environmental protection, energy conversion and other fields.
3. Filler: can be used in coatings, adhesives, rubber and other materials to improve its performance.
4. Pharmaceutical field: can be used for the preparation of controlled release drugs, increase drug stability, etc.
The methods of preparing active silica micropowder mainly include sol-gel method, hydrothermal method, gas phase method, etc. Among them, the sol-gel method is the most common method, that is, the gel process of Sol in liquid to obtain particulate silica.
in the use of active silica powder need to pay attention to some safety information:
1. It is recommended to operate in a well-ventilated place to avoid inhalation of micro-powdered substances.
2. Avoid direct contact with skin. If there is contact, rinse with water immediately.
3. Make sure to use personal protective equipment, such as gloves and glasses.
4. Storage should avoid contact with organic substances, strong acids, strong bases, etc., so as to avoid reaction.
