Technical features of non-stick coating for sandwich baking plate

The selection of non-stick coating materials for sandwich baking plate is crucial, as it directly affects the performance, safety and durability of the baking plate. Common non-stick coating materials include PTFE, ceramic coating, nano-composite coating, etc.
PTFE: Due to its high temperature resistance, corrosion resistance, and non-stick properties, it is widely used in cooking utensils such as baking plates. PTFE coating can remain stable at high temperatures, is not easy to fall off, and has good lubricity, effectively reducing food adhesion.
Ceramic coating: Ceramic coating has high hardness and wear resistance, and can resist scratches and wear to a certain extent. At the same time, ceramic coating also has good high temperature resistance and environmental protection, does not contain harmful substances, and meets food safety standards.
Nano-composite coating: Nano-composite coating combines the advantages of multiple materials, and uses nanotechnology to compound different materials at the nanoscale to form a new material with good performance. Nano-composite coating not only has non-stick properties, but may also show better performance in hardness, wear resistance, corrosion resistance, etc.
Performance optimization
After selecting a suitable coating material, it is necessary to further improve its performance by optimizing the coating formula and process. For example:
Coating thickness control: Reasonable coating thickness can ensure the adhesion and wear resistance of the coating, while avoiding the decrease in thermal conductivity caused by excessive thickness.
Microstructure design: Through micro-nano surface treatment technology, microstructures such as micropores and micro-convexities are formed on the coating surface. These structures can further reduce the adhesion between food and coating and improve non-stick performance.
Cross-linking curing: Cross-linking curing technology is used to improve the bonding strength between the coating and the substrate, ensuring that the coating is not easy to fall off during long-term use.
