Problems solved by technology

[0005] However, the environment in which the base of the steel silo comes into contact with is relatively complex. After a long period of time, surface corrosion is prone to occur. After a long period of extensive corrosion, the storage environment in the steel silo will gradually be destroyed, resulting in corruption of the internal storage items. Therefore, it is necessary to The base of the steel silo is protected to a certain extent

Embodiment 1

[0075] A method for treating the base of a corrosion-resistant steel silo, comprising the following steps:

[0076] (1) Cleaning and polishing:

[0077] The base of the steel silo was cleaned with acetone to remove surface oil, and then cleaned with an ethanol solution with a mass fraction of 30%. After drying, it was polished with sandpaper of different meshes to obtain a polished steel silo base; The grinding with sandpaper of different mesh numbers is to use 300 mesh, 600 mesh and 1200 mesh sandpaper to polish successively; wherein, the 300 mesh sandpaper is polished for 20 minutes; the 600 mesh sandpaper is polished for 35 minutes; the 1200 mesh sandpaper is polished for 1 hour.

[0078] (2) Steel silo base pretreatment:

[0079] Preparation of pretreatment solution: add silane coupling agent, maleic anhydride, strontium chloride, absolute ethanol, and deionized water to the reaction kettle in sequence, heat to 50°C, and stir for 30 minutes to obtain the pretreatment solu...

Abstract

The invention discloses a method for treating the base of a corrosion-resistant steel silo; it relates to the technical field of steel silo equipment and includes the following steps: (1) cleaning and polishing; (2) pretreatment of the base of the steel silo; (3) preparation of a coating solution; ( 4) Coating treatment; in the method of the present invention, after the pretreatment liquid is coated on the surface of the steel silo base, a dense and uniform covering film can be formed, and the covering film formed by the pretreatment liquid in the present invention on the surface of the steel silo base Thick and not easy to damage.

Description

technical field [0001] The invention belongs to the technical field of steel silo equipment, in particular to a method for treating the base of a corrosion-resistant steel silo. Background technique [0002] The steel silo is mainly used to store cement, fly ash, slag powder, clinker, grain and other powder and granular materials. [0003] The application and development of my country's steel silo technology in the grain industry started relatively late. In 1982, Honghe Farm in Heilongjiang Province imported galvanized corrugated sheet assembled steel silos from the United States, which is the earliest modern steel silo group that appeared in China. In the 1980s, the construction of steel silos in my country achieved unprecedented development. Heilongjiang Province Yingchun Machinery Factory has introduced and absorbed the complete set of technology and special equipment production line of American prefabricated steel silos. According to foreign advanced technology, design...
