AI Technical Summary
Existing aluminum alloy cookware suffers from poor non-stick properties, insufficient wear resistance, easy cracking, heavy metal contamination, and aluminum leaching, making it difficult to achieve a comprehensive effect of no chemical coating, no heavy metals, superhydrophobic, high hardness and wear resistance, high temperature resistance, and hydrophobic self-healing.
Using a rare earth modified aluminum alloy matrix, a double-layer gradient composite film of SiO2 and SiC particles is formed, combined with high-temperature melting chemical bonding of stearic acid to seal the pores, thus forming a gradient composite rare earth modified aluminum alloy anodized cookware with active hydrophobicity and hydrophobic self-reinforcing and self-healing properties, achieving integrated treatment of the inner and outer surfaces.
It achieves comprehensive performance with high safety, high temperature resistance, wear resistance, long-lasting superhydrophobicity, and green environmental protection, which improves the service life and health safety of cookware, reduces the risk of aluminum leaching, and meets the requirements of green manufacturing.
