A large amount of steel is needed in the design of steel structure project, but if the steel used in construction rusts a lot, it will greatly shorten the service life. For personal safety is also a challenge, the collapse of the house is common, in recent years more and more attention, today Fangtong steel structure will teach you some rust removal methods!

Remove dust, oil and sundries on the surface of steel structure before construction to ensure the surface is clean. Before construction, the coating should be stirred well with stirring gun, and if it is too thick, it can be diluted with 200# solvent gasoline to make it easy to be constructed. The paint brush and roller brush should be used to brush the coating in layers, and the coating should be thin, generally 0.4mm, in order to enhance the bonding strength between the coating and the steel substrate.

Can be divided into solvent-based and water-based two categories, the two types of coatings selected by the fire components are basically the same, so it is difficult to say how much difference in their fire performance, the solvent selected to use the film-forming substances. Solvent-based fireproof coating film-forming substances are generally selected chlorinated rubber, over lv vinyl, amino resins, phenolic resins, etc., the use of solvents for the spray paint sparse and so on. Water-based fireproof coating film-forming substances.
