Plasma Spraying Ceramic Coating Process

Application of Thermal Spraying Technology

1. Applications of Arc-Sprayed Metal Coatings: Various containers and storage tanks made of ordinary A3 steel can have their surfaces coated with stainless steel materials such as 1Cr18Ni9Ti, 0Cr, or 00Cr, followed by pore-sealing treatment. This approach has been widely adopted as an alternative to manufacturing these components entirely from stainless steel. Specific applications include spraying aluminum, tin, zinc, lead, and stainless steel coatings on the inner surfaces of carbonization towers in fertilizer plants, gas holders, wine storage tanks, beer fermentation tanks, distillation columns, and various chemical processing vessels. Additionally, this method is used for repairing large gate valves and butterfly valves. 2. Applications of Plasma-Sprayed Ceramic Coatings: Food and chemical industry enterprises use A3 steel reactors that are newly manufactured or refurbished by spraying ceramic coatings—such as alumina, titanium dioxide, and chromium oxide—on their inner surfaces, replacing traditional enamel coatings or localized enamel repairs. When enamel reactors or agitator blades, impellers, and other components suffer local damage and become unusable, they can be repaired by using the ZK1532 metal-ceramic powder high-velocity flame spray gun to apply a ceramic coating, followed by pore-sealing treatment to restore them to like-new condition. 3. Applications of Flame-Sprayed Plastic Coatings: Flame-spraying plastic coatings, also known as flame-plastic spraying, are primarily used for powder coating aimed at corrosion resistance. This technique features relatively thick coatings, simple application procedures, lightweight and portable equipment that can be easily transported to construction sites. It enables direct on-site spraying of various acid-, alkali-, and salt-resistant plastic coatings without the need for heating or curing equipment, making it especially suitable for large-scale flame-plastic spraying operations at construction sites. These three thermal spraying technologies have now been extensively applied in sealing solutions within the food industry. Although the above introduction provides only a brief overview of the applications of thermal spraying technology in the food industry, we hope it has been helpful.
