Is an enamel reactor the same as a glass-lined reactor?

There is no difference; it’s the same thing. The proper term should be glass-lined reactor

What was said on the second floor is correct. The correct term is glass-lined reactor.

The following is what I found on Baidu. The differences aren’t very significant at present, but the main distinction lies in comparison with everyday-use enamel. The enamel reactors and glass-lined reactors mentioned in the context of chemical equipment are actually the same thing, as the main components of the glaze used are similar. Difference between porcelain enamel and glass lining; differences in their properties. Porcelain enamel: A metal surface is coated with multiple layers of ceramic glaze, which are then fired in a furnace at around 800°C; as a result of physical and chemical reactions, a composite material is formed in which the glaze bonds with the metal. Metals for enamel include: copper, aluminum, low-carbon steel, etc. Mainly used for decoration and in jewelry, as well as for surface decoration and corrosion protection of building materials; also used in daily products such as bathtubs, water heaters, and water tanks ； Therefore, although enamel is classified into artistic enamel, household enamel, sanitary enamel, architectural enamel, cast-iron enamel, etc., it is generally referred to as household enamel. Glass lining: A glassy glaze with special properties, which is formed on a metal substrate by heating it in a furnace at around 820–950°C. A metal matrix refers to carbon steel, stainless steel containers, pipes, and other materials of certain strength used in various petrochemical equipment ； Primarily used as anti-corrosion equipment for chemical processes involving high and low temperatures, pressure, and corrosive environments, for reactions and storage purposes; these devices are collectively referred to as glass-lined equipment! Enameled steel was known as industrial enamel before the late 1960s! Enameled steel: Enameled steel equipment is made by applying a ceramic glaze with a high silicon content to the surface of metal, and then firing it at 950°C to ensure that the glaze adheres tightly to the surface of the metal substrate. Therefore, it has the dual advantages of glass-like chemical stability and metal strength. Enameled equipment is widely used in industrial production and scientific research across sectors such as chemicals, pharmaceuticals, dyes, pesticides, organic synthesis, petroleum, food manufacturing, and the defense industry for processes including reaction, evaporation, concentration, synthesis, extraction, polymerization, saponification, mineralization, chlorination, and nitration, serving as a substitute for expensive stainless steel and non-ferrous metals. Corrosion resistance: It exhibits excellent resistance to corrosion in various concentrations of inorganic acids, organic acids, organic solvents, and weak bases. However, it is not suitable for strong bases, hydrofluoric acid, and fluoride-containing media, as well as phosphoric acid at temperatures above 180°C and concentrations above 30%. Glass-lined equipment mainly includes: reaction tanks, storage tanks, distillation tanks, and condensers. The main standards governing its design and manufacture are GB150-1998 \"Steel Pressure Vessels\", the \"Regulations on Safety Inspection of Pressure Vessels\", and HG2432-2001 \"Technical Requirements for Glass-Lined Equipment\". Enameling is a composite material in which one or several layers of enamel are applied to a metal surface, and through firing, a physical and chemical reaction occurs between them, resulting in a strong bond. Formerly known as enamel. It possesses the mechanical strength and workability inherent to metals, as well as the corrosion resistance, wear resistance, heat resistance, non-toxicity, and decorative properties of coatings. Enameling originated from glass decorating metals. It first appeared in ancient Egypt, followed by Greece. In the 6th century, European inlaid enamel, cut-out enamel, relief enamel, translucent enamel, and painted enamel were successively developed. China began to develop enamel in the 8th century, and by the end of the 14th century this craft had become increasingly sophisticated. Artworks produced during the Jingtai era of the Ming Dynasty in the mid-15th century were particularly renowned, which is why it came to be known as Jingtai blue. In the early 19th century, cast-iron enamel was developed in Europe, laying the foundation for enamel to evolve from a craft item to a household good; however, due to the backward casting techniques of that time, the use of cast-iron enamel was limited. In the mid-19th century, the development of various industries led to the emergence of steel plate enamel, marking a new era for modern enamel. From the late 19th century to the first half of the 20th century, the emergence of various porcelain glazes with different properties, the wider use of steel plates and other metal materials, as well as continuous improvements in refractory materials, kilns, and enameling techniques, all contributed to accelerating the development of the enamel industry. There are many types of enamel, which can be classified by use into artistic enamel, household enamel, sanitary enamel, architectural enamel, industrial enamel, and special-purpose enamel. The production of enamel involves main processes such as glaze preparation, substrate preparation, coating, drying, firing, and inspection. For artistic enamel, household enamel, sanitary enamel, architectural enamel, etc., coloring and assembly are also required for aesthetic decoration and practical use. Industrial enamel equipment must be inspected before being assembled.

But the main difference lies in it compared to everyday-use enamel; the enamel reactors and glass-lined reactors referred to in the context of chemical equipment are actually the same thing, as the main components of the glaze used are similar.
