Description

Technical Field

[0002] Metal drums include nine categories: steel drums, yellow phosphorus packaging drums, solid alkali drums, calcium carbide packaging drums, steel pails, and square drums. Their primary advantages are high mechanical strength, pressure resistance, and impact resistance, making them the primary packaging containers for liquid hazardous chemicals. Internal spray coating of steel drums involves applying or coating the inner surface of the drum that comes into contact with the contents, creating a uniform barrier between the drum and the contents. The essential properties of internal spray coating materials are excellent adhesion to the drum base material, good resistance to comprehensive media corrosion, non-toxicity and odorlessness after drying, and good processability—meaning they must perform well and meet the requirements of the drum manufacturing process. Currently, the three most commonly used internal spray coating materials for steel drums in China are epoxy resin coatings, polyvinyl fluoride coatings, and phenolic resin coatings.

[0003] For example, according to Chinese patent publication number CN206454831U, a barrel internal spraying device belongs to the technical field of steel barrel manufacturing equipment. The barrel internal spraying device consists of a program controller, a mounting base, a spraying element, a spray box, a push cylinder, a driving shaft, a driven shaft, and a discharge rack.
