What is the role of epoxy resin adding silicon carbide powder

The addition of silicon powder to epoxy resin, like glass microspheres, is to increase its mechanical strength and hardness. Due to the very large specific surface area, silica powder can well strengthen the bridge between high epoxy equivalent monomer and amines or anhydrides as curing agents, forming a more stable three-dimensional insoluble cross-linking structure.

Some low-priced epoxy boards are directly added with gypsum powder and kaolin, etc., and the functions are almost the same, please refer to (glass fiber is also one of the commonly used reinforcement accessories).

In this case, consider whether it is caused by poor mixing. Theoretically, because silica conducts heat better than resin, the addition of silica powder should help reduce the temperature rise. However, due to the addition of solid powder, there may be many unrecognizable gaps and voids due to poor mixing.

Inorganic fillers include silica powder, barium sulfate powder, alumina powder, mica powder, titanium dioxide, etc., but in general, these will affect the transparency of the material. In other words, the more you add, the less transparency you have.

Silicon carbide powder is an important inorganic material, which is mainly used to manufacture ceramics, electronic devices, thermal conductive materials, coatings, etc. The effect of silicon carbide powder and additives is mainly manifested in the following aspects:

1.Improves the dispersion of silicon carbide powders. After adding additives to silicon carbide powder, the adsorption between particles can be reduced, and its dispersion and stability in the liquid phase system can be improved.

2.Improve the wettability of silicon carbide powder in the liquid phase. The silicon carbide powder with the addition of the mountain cover agent can increase the mutual force between it and the liquid phase, thereby improving its wettability in the liquid phase, which is conducive to reducing the exhaust porosity of the material and improving the density of the material.

3.Increase the agglomeration of silicon carbide powder. The additives can form a protective film on the powder surface of silicon carbide powder, and after the chemical reaction occurs, it can increase the binding force between the particles and improve the mechanical properties and wear resistance of the material.

4.Improve the thermal stability of silicon carbide powder. After adding additives, a protective layer will be formed on the surface of silicon carbide powder, which can reduce its sensitivity to environmental factors such as oxygen and water vapor, thereby improving its thermal stability and corrosion resistance.

Overall, silicon carbide powders and additives help to improve their performance and stability, expanding their range of applications.

Silicon carbide powder plus additives means that a certain amount of additives are added to silicon carbide powder to improve its physical and chemical properties, so that it can or cover better adapt to specific application needs.

Commonly used silicon carbide powder additives include plasticizers, flow agents, toughening agents, stabilizers and dust lubricants. The amount and type of additives added to these additives will vary depending on the specific application needs and processing process. For example, when silicon carbide powder is used in the preparation of ceramic products, the addition of some toughening agents and plasticizers can improve its fracture toughness and processing processability.

The processing method of silicon carbide powder plus additives will also vary depending on the specific situation. Some additives can be mixed with silicon carbide powders by dry or wet mixing, while others need to be dissolved in specific solvents before being added to silicon carbide powders. Overall, the addition of additives can facilitate the specific application of silicon carbide powders and improve their processability and service life.

Summary. Silicon carbide powder additives refer to adding a certain amount of other substances to silicon carbide powder to improve the performance of silicon carbide powder, so that it has better mechanical properties, thermal stability and corrosion resistance.
