TB 2112-1990 "Railway 10-ton container surface preparation and painting" is a railway industry standard, specifying the technical requirements for surface preparation and painting of 10-ton railway containers. The content covers steel surface pretreatment (derusting grade, asperity control), coating process (primer, intermediate paint, topcoat supporting system and coating times), coating performance indicators (adhesion, salt fog resistance, weathering resistance, etc.), Appearance mass requirements (uniform color, no sag, bubble) and inspection rules. This standard applies to the anti-corrosion painting of railway 10-ton containers. Through standardized surface preparation and coating construction, the anti-corrosion and anti-abrasion ability of containers in the transportation environment is improved, and the structural strength and service life of the box are guaranteed. Provide technical basis for the manufacture, maintenance and mass control of railway containers.
