Description

Anti-corrosion truck scale

Technical Field

The utility model relates to an anticorrosion truck scale.

Background

Truck scales, also known as Truck scales (Truck scales), are large scales that are placed on the ground and are commonly used to weigh the tons of a Truck, a lorry, etc. and are the main weighing devices used in large cargo metering, such as factories, mines, and merchants.

In order to improve the application environment of the truck scale, the surface of the truck scale is required to be coated frequently so as to reduce the phenomenon of rusting or corrosion of the surface of the truck scale in some application occasions. The existing standard automobile scale surface coating is usually formed by coating common paint, for example, in an existing automobile scale, the surface of the automobile scale is sprayed with the common polyurethane paint or high-solid paint, as shown in fig. 1, and the surface of the automobile scale 90 is coated with a layer of paint 91.

However, the inventor finds that in some application occasions with higher requirements on corrosion, such as the heavy industrial pollution area C5-I (industrial) and C5-M (marine) environments specified by ISO12944, the surface corrosion rate of the automobile scale is increased, the working condition requirements cannot be met, and the service life of the automobile scale is shortened by using the traditional automobile scale in the similar occasions.
