Embodiment Construction

[0008] A method for anti-corrosion of tinplate, coating the anti-corrosion composite layer on the tinplate, the coating process of the anti-corrosion composite layer comprises the following steps: the first step is to clean the tinplate substrate, and the tinplate substrate adopts ethanol to remove the tinplate Pollutants such as grease on the surface; the second step is to carry out sandblasting treatment. The sandblasting treatment adopts chilled cast iron sand with a particle size of 0.2-0.5mm. The compressed air used for sandblasting must be clean and dry, and the air pressure is 10-20MPa; The third step is to spray anti-corrosion paint, the anti-corrosion finish paint sprayed in the third step is organic fluorocarbon paint, the thickness of the anti-corrosion finish paint is 0.1 ~ 0.5mm, and the thickness of the anti-corrosion finish paint is based on Depending on the thickness and the nature of the contents of the container from which it is to be made. The surface of the...

Abstract

The invention provides a corrosion preventing method for a tinplate. The tinplate is coated with a corrosion preventing composite layer, wherein a corrosion preventing composite layer coating process comprises the following steps: firstly, cleaning a tinplate substrate; secondly, performing sand-blasting treatment; thirdly, spraying anti-corrosive paint; in the first step, pollutants on the surface of the tinplate is cleaned by using ethanol; in the second step, chilled cast iron sand with the particle size of 0.2 to 0.5 mm is adopted for the sand-blasting treatment; in the third step, the sprayed anti-corrosive paint is organic fluorocarbon paint. According to the corrosion preventing method for the tinplate, the effect of preventing corrosion can be achieved effectively; the service life of the tinplate is prolonged; the corrosion preventing method has the advantages of convenience, practicability and low cost.

Description

technical field [0001] The invention belongs to anticorrosion methods, in particular to a method for anticorrosion of tinplate. Background technique [0002] As a common metal raw material for packaging containers, tinplate has been widely used by people. There are many tinplate products, such as household aerosol insecticide packaging bottles, hair gel packaging bottles, air purification aerosol packaging bottles, food packaging cans, etc. Some of these products are slightly acidic solutions, which are corrosive to tinplate, which can easily lead to corrosion and perforation of tinplate products, resulting in liquid leakage. danger and injury. Contents of the invention [0003] The problem to be solved by the present invention is to provide a method for anti-corrosion of tinplate, which can effectively prevent corrosion and prolong the service life of tinplate based on the coating of an anti-corrosion composite layer on the tinplate base. [0004] For solving the proble...
