Why do we need to add silicon carbide to the non-stick pan coating?
Silicon carbide has extremely high hardness, good chemical properties and thermal conductivity. The shape is similar to a hexagonal crystal. It mainly uses petroleum coke and high-quality silicon as the main raw materials, and uses salt as an additive. It is refined and shaped by a resistance furnace at high temperature. Because of the various excellent characteristics of its products, it is used in many non-stick cookware coatings. Let’s take a look at the application characteristics of silicon carbide powder in non-stick cookware coatings:
1. The amount of resin used: Compared with various shapes, the surface area of the sphere is the smallest. Therefore, the amount of resin used is also the least, which will greatly reduce the accumulation of particles. If a wider particle size allows small microspheres to fill the gaps of large microspheres, the final result will be the added amount, high solid content, relatively low VOC, and relatively reduced dosage of other ingredients.
2. Reduced viscosity: Unlike particles of other shapes, silicon carbide ceramic powder is more flexible between two objects. Therefore, this indicates that the product has low viscosity, good fluidity, and correspondingly better sprayability. Big improvement.
3. The silicon carbide ceramic powder filled with hard granular microspheres not only acts on the coating to increase its hardness, but also has particularly good wear resistance and scrub resistance. It will not affect the quality of use at any temperature, has excellent corrosion resistance and chemical resistance, and has a long service life.
4. Because it is spherical, the light passing through the sphere is scattered and slow, and the light is distributed in various positions. Therefore, the covering ability of the coating is super strong.
5. Unlike other filling materials, when the crystalline silicon in the silicon carbide ceramic powder does not exceed the standard content, no toxic substances will appear.
The above points are the characteristics of the use of silicon carbide in non-stick coatings. Friends who need a large amount of silicon carbide can consult by phone.
