Abstract

The invention discloses a renovated iron drum production process. Cleaning solvent adopted in high-pressure cleaning comprises 40-60 weight parts of propanediol butyl ether, 16-20 weight parts of xylene, 10-30 weight parts of surface active agent, 6-8 weight parts of polyethylene glycol, 0.5-3 weight parts of coconut oil fatty acid diethanolamide, 3-5 weight parts of corrosion inhibitor, 0.5-1 weight part of modified polyether defoaming agent and 2-4 weight parts of stabilizing agent; then, water is used for washing the internals and the externals of drums; during cleaning, the cleaning solvent is removed by adopting a pressure difference; the shot blasting treatment is performed on the internal and the externals of the iron drums; shots of a shot blasting machine are stainless steel shotsor iron shots with diameters of 1.5-3 mm; a dust removing system is arranged on the shot blasting machine; and the powder spraying, the paint spraying and the drying are performed at 170-180 DEG C. The renovated iron drum production process controls each process link in a refined mode, is not easy to generate leakage at the bottoms of the renovated drums and uniform and beautiful in powder spraying to the surfaces, and only reaches the defective rate of about 2%.

Description

technical field [0001] The invention relates to a production process of refurbished iron barrels. Background technique [0002] When refurbishing waste packaging barrels, it is found that the rate of defective products is high, the bottom of the refurbished barrels is prone to leakage, and the uneven powder spraying will seriously affect the quality and appearance of the refurbished barrels. The application number is 2017108682604, which discloses a method for refurbishing and treating waste packaging barrels. The method is simple, easy to operate, environmentally friendly and safe, but the defective rate is still about 8-10%. Contents of the invention [0003] The technical problem to be solved by the invention is to overcome the defect of high defective rate of refurbished drums in the prior art, and provide a production process of refurbished iron drums with low defective rate. [0004] In order to solve the problems of the technologies described above, the present inv...
