What Is The Application Prospect Of Micro Silica Powder (Silica Fume) In The Coating Industry?

The application prospect of Ewende micro silica powder in coating industry is relatively broad, mainly reflected in the following aspects:

1. Demand for performance enhancement drives the application:

- Enhancement of durability: As the quality of coatings continues to improve, the demand for coatings with better durability continues to grow. Micro silica powder can enhance the coating's resistance to environmental factors, such as ultraviolet resistance, chemical corrosion resistance, weathering resistance. In areas such as outdoor construction and industrial facilities that are exposed to the outside environment for long periods of time, coatings with micro silica powders can maintain the appearance and performance of the coating better and reduce maintenance costs, so there is a promising future for their application in these areas.

- Improvement of strength and abrasion resistance: For surfaces that are often subject to friction and abrasion, such as floors and mechanical surfaces, coatings with high hardness and abrasion resistance are required. Micro silica powder can increase the hardness and abrasion resistance of coatings, which can meet the needs of these special scenarios, and has a large application potential in industrial flooring, machinery coating and other fields.

- Improvement of seepage resistance: In the fields of building waterproofing and underground engineering, the seepage resistance of coatings is crucial. The filling effect of micro silica powder can reduce the porosity of the coating, reduce the infiltration of water and gas, and can effectively improve the waterproof, moisture-proof and anti-gas permeability performance of the coating, which is of great significance for guaranteeing the safety and durability of the building structure.

2. Environmental protection demand brings development opportunities:

- Boosting the development of water-based coatings: Under the background of increasingly strict environmental protection policies, low-pollution and low-energy coating products such as water-based coatings have become the development trend. Micro silica powder can be used as an additive for water-based coatings to improve the performance of water-based coatings, such as improving their hardness, abrasion resistance, seepage resistance, etc., which can help water-based coatings better meet the market demand and promote the wide application of water-based coatings.

- Reduce the emission of harmful substances: Traditional coatings may contain some harmful substances, such as volatile organic compounds (VOC), which are harmful to the environment and human health. Micro silica powder can partially replace some traditional fillers and additives, reduce the content of harmful substances in coatings, reduce the environmental impact of coatings, and meet the requirements of environmental protection.

3. Growth in demand for special functional coatings:

- Fireproof coatings: The demand for fireproof coatings is increasing in buildings, ships, tunnels and other places with high fireproofing requirements. Micro silica powder can synergize with other fireproof materials to improve the fireproof performance of coatings, which has important application value in the field of fireproof coatings.

- Anti-corrosion coatings: There is a continuous demand for anti-corrosion coatings in industrial facilities, marine engineering and other fields. Micro silica powder can enhance the anticorrosion effect of anticorrosion coatings and prolong the service life of coated objects, and has good application prospects in the field of anticorrosion coatings.

- Antibacterial Coatings: The demand for antimicrobial coatings is gradually emerging in places with high hygienic requirements, such as medical and food processing. Micro silica powder can be used as the carrier or additive of antibacterial coatings to improve the antibacterial performance of coatings, which has a broad market prospect.

4. Demand driven by the development of the construction industry:

- Decorative architectural coatings: As people's demand for the quality of architectural decoration continues to improve, the market demand for decorative architectural coatings is also growing. Micro silica powder can improve the performance of architectural decorative coatings, such as improving its gloss, color stability, etc., providing better effects for architectural decoration.

- Building energy-saving coatings: In the field of building energy-saving, energy-saving coatings with the functions of heat preservation and insulation are attracting attention. Micro silica powder can be used as a filler in energy-saving coatings to improve the thermal insulation and heat-insulating properties of the coatings, which helps to reduce the energy consumption of the building and is in line with the development trend of building energy saving.

5. Technological progress expands application fields:

- Application of nanotechnology: With the continuous development of nanotechnology, the preparation and application of nanoscale micro silicon powder has become a research hotspot. Nanoscale micro silica powder has higher specific surface area and activity, which can better improve the performance of coatings and bring new development opportunities for the coating industry.

- Research and development of composite materials: micro silica powder can be compounded with other materials to prepare coatings with special properties. For example, composite with polymer materials can be prepared with excellent mechanical properties and chemical corrosion resistant coatings, composite with metal materials can be prepared with conductive, thermal conductivity and other functions of the coating, expanding the application areas of coatings.
