The present invention is to solve the above-described problems, and an object of the present invention is to provide a surface inspection method for a low-magnetic anchor chain.
In order to achieve the technical purpose and achieve the technical requirements, the invention adopts the technical scheme that:
a chain anticorrosion treatment method is characterized in that: the method comprises the following steps:
the method comprises the following steps that firstly, a plurality of chains are paved on a clean ground, and the parts of the chain rings, which are in contact with the chain rings, are loosened by using a tool so as to apply a coating;
secondly, cleaning the surface of the loosened contact part by using a grinding wheel or abrasive paper before applying the coating because steel particles at the contact part of the chain ring and the chain ring can not reach during shot blasting;
thirdly, brushing or spraying a primer on the front side of the chain, turning the chain over 180 degrees after the interval is not less than 1 day, loosening the contact part of the chain ring and the chain ring again by using a tool after turning, and brushing or spraying the bottom surface of the chain; the primer adopts an anti-corrosion primer added with zinc powder, and the zinc content in the anti-corrosion primer is 50-80%;
after the primer is dried, brushing or spraying the intermediate layer paint according to the method in the third step;
fifth, after the intermediate layer paint is dried, brushing or spraying finish paint according to the method of the third step;
step six, a lifting machine is adopted during packaging, and slings penetrate through chain links every a plurality of ring numbers; slings of soft material should be used in order not to damage the coating.
Preferably, in the first step, when the plurality of chains are laid flat, the distance between the chains is not less than 20 cm.
Preferably, when the contact part of the chain ring and the chain ring in the step three is loosened, the used tool is coated with a soft material so as not to damage the coating.
Compared with the traditional structure, the invention has the beneficial effects that: the chain has the advantages of easy construction, no sagging defect, good corrosion resistance, capability of ensuring that the chain still can keep good corrosion resistance effect under the condition of damage, capability of meeting the requirement of long-term service of the chain in a corrosive environment, and particular suitability for large-size long chains.
