METHOD FOR FORMING THE PROTECTIVE COATING OF THE RAILWAY CAR BODY Russian patent published in 2022 - IPC B61D17/18 B05D1/02 

FIELD: protective coatings.

SUBSTANCE: invention relates to the field of creating protective coatings, in particular anticorrosive coatings for freight railcars. The method for forming the protective coating of the body of a railway car includes the preparation of the body, which consists in cleaning the inner surfaces of the body intended for applying a protective coating to them, spraying a protective polymer layer coating on the cleaned inner surfaces of the body. The protective coating is applied by successive spraying of polymer material on the inner surfaces of the body in layers of two to five layers. The polymer material is sprayed in mutually intersecting directions in layers, spraying in each layer from the middle part of each inner surface to its extreme parts. After applying the protective coating, its exposure is carried out for at least one hour.

EFFECT: invention increases the reliability and improves the anticorrosive properties of the protective coating.
