Glass-fused-to-steel Technology

Glass-fused-to-steel technology is a specialized technique for coating metal surfaces to provide corrosion resistance, wear resistance, high-temperature resistance, and resistance to chemical corrosion. This technology is commonly applied in the production of enamel products, such as enamelware, enamel bathtubs, and kitchen equipment with enameled surfaces. Here are some basic points about enamel technology:

Enamel Material: The primary component of enamel is vitreous enamel, typically a mixture of silicate and oxide. This enamel exhibits highly ceramic properties, forming a robust, smooth, and corrosion-resistant coating on metal surfaces.

Enamel Process: The basic enamel process involves cleaning and preparing the metal surface, followed by applying enamel coating to the metal surface. Subsequently, the metal products with enamel coating are sent into a high-temperature furnace for firing. At high temperatures, the enamel coating melts and fuses onto the metal surface, forming a sturdy enamel layer. This process is also known as firing or enameling.

Characteristics: Enamel coatings possess a range of excellent properties, including corrosion resistance, chemical corrosion resistance, smoothness, wear resistance, and high-temperature resistance. These qualities make enamel products widely applicable in various uses.
