Embodiment Construction

[0011] The present invention is described in further detail below in conjunction with examples: firstly, sandblasting the metal surface to make the surface reach the effect of Sa2.5 level, then brush the primer resin on the metal surface in the same direction, and then brush the primer again after curing Resin, after the primer resin is cured, spread a layer of resin cement on its surface, and then carry out reinforcement layers laid alternately with glass fiber cloth to the required thickness of 4mm, then spread a resin-rich layer, and finally spread a layer on the surface Plastic film, peel off after curing.

[0012] A method for laying a protective layer on the surface of an iron storage tank. The weight formula of the primer resin is as follows: 100 parts of primer resin, 3 parts of curing agent, and 2 parts of accelerator.

Abstract

The invention discloses a method for laying a protection layer on the surface of an iron storage tank. The technical scheme of the invention is characterized in that the method comprises the following steps: carrying out sand blast treatment of the metal surface to make the surface reach an Sa2.5 grade effect, carrying out isodirectional brush coating of a primer resin of the metal surface, allowing the obtained coat to solidify, carrying out isodirectional brush coating of the primer resin again, allowing the obtained new coat to solidify, laying a layer of a resin mortar on the surface of the coat, laying a reinforcement layer obtained through laying glass fiber clothes in an alternated manner to a required thickness of 3-5mm, laying a resin-rich layer, laying a layer of a plastic film on the surface, allowing to solidify, and uncovering the plastic film. The method for laying the protection layer on the surface of the iron storage tank has the characteristics of strong adhesion of the metal and the glass fiber reinforced plastic protection layer, long use time, no cracking, no exfoliation, and flattened and beautiful surface.

Description

[0001] technical field [0002] The invention relates to a method for laying a protective layer on the surface of an iron storage tank, which belongs to the field of chemical equipment. Background technique [0003] Iron storage tanks are widely used in chemical, mining, pharmaceutical and other industries to hold acid and alkaline media. Because iron storage tanks are not resistant to corrosion by chemical media such as acids, it is often necessary to carry out anti-corrosion on iron storage tanks. Nowadays, the main methods of anticorrosion for storage tanks are brushing corrosion-resistant paint, lining with anti-corrosion rubber layer and lining with glass fiber reinforced plastic, etc. However, due to the material characteristics of the metal surface, the existing vinyl resin has the problem of poor adhesion to the metal surface, and quality accidents such as shelling, bubbling, and delamination often occur. Contents of the invention [0004] The ninth object of ...
