Enameled steel reaction kettle, enameled reactor, enameled reaction tank
Thread Content
An enamel-lined reaction kettle is a steel chemical container equipped with a corrosion-resistant glass lining; the steel tank body ensures its pressure resistance, while the glass lining applied inside provides it with reliable corrosion resistance. This unique combination of corrosion resistance greatly expands the range of applications for such equipment, enabling its use in various industries including chemicals, petrochemicals, pesticides, pharmaceuticals, metallurgy, and food processing. Under a wide range of chemical reaction conditions, enamel-lined reaction vessels can not only replace expensive stainless steel containers but are also widely used in corrosive environments where stainless steel containers cannot be used. The corrosion resistance of enamel reaction vessels is based on the formation of a siloxane protective film after the glass lining comes into contact with the medium; this film prevents the medium from corroding the vessel. When the glass-lined layer comes into contact with strong alkaline solutions, no silicoxy protective film can form on its surface, allowing the alkali to continue to erode deeper into the glass layer. The higher the concentration of the strong alkali and the higher the temperature, the greater the degree of erosion; boiling strong alkaline solutions have the greatest erosive capacity.
Non-metallic coatings, especially those that are free of certain substances, offer significant advantages in addressing acid, base, and salt-related issues. Therefore, an appropriate coating can be selected based on the operating conditions of the equipment.
