Study on Anticorrosive Coating and Adhesion Test of Steel Structure Members
The on-site coating adhesion inspection was carried out on steel structure members,and it was found that the hardness of the on-site coating was soft and the adhesion was low;moreover,it was found that the steel substrate in some areas of the members was corroded,and the on-site coating adhesion in the rusted area was lower.Based on the coating sample information of steel structure members,the coating samples of on-site members were confirmed by comparing the samples provided by the factory with the coating samples of on-site members.The epoxy micaceous iron oxide used in the steel structure members has low strength and can also meet the adhesion requirements of various coatings in GB 50205-2020;however,the coating on the corroded areas of steel structure members should be repolished and brushed.
