Problems solved by technology

However, the use of copper plating requires a strict, standardized and perfect treatment process and production line, which greatly increases the production cost, and because the plating solution contains cyanide, a large amount of waste liquid is discharged, and the damage to the natural environment is even greater. It is a national restriction and Prohibition of new industries

Description

technical field [0001] The invention belongs to the technical field of paint coating, and in particular relates to a device and a method for coating the inner wall of an oil casing collar with a nano-friction-reducing paint. Background technique [0002] The new nano anti-friction coating has excellent anti-friction properties, and it can greatly reduce the friction moment when coated on the inner wall of the oil casing collar. Since this product is the latest researched coating, there is no corresponding coating equipment on the market at present. In order to realize the industrial application of nano-friction-reducing coatings and improve the service life of oil casings, the research corresponding to this new type of nano-friction-reducing coatings Coating equipment is of great significance. [0003] In order to prevent the sticking problem of the existing oil casing pipes when making and breaking out, generally speaking, the couplings are generally phosphating, and it is...
