Abstract
Disclosed are a steel container and component thereof with galvanic protection coatings, comprising a steel container and components thereof. The outer surfaces of the steel container and the components are provided with zincic galvanic protection coatings. The utility model is easy to construct with good antisepsis performance; rust is not easy to diffuse to the coatings, thus prolonging the service life and making the service life of the coatings comparable with that of the pot galvanization.
Description
The utility model relates to the steel vessel and the member of the cathodic protection coatings that a kind of outside face not only insulate but also conduct electricity.
As everyone knows; corrosion beharvior for the anti-air environment rough weather of improving steel part; prolong its service life; generally adopt at steel part outside face coating paint and form one deck is protected steel part to the barrier of air outside face; to prevent the steel part corrosion; influence inherent quality and shorten workpiece service life; but paint is subjected to the influence of air environment easily and corrosion takes place; therefore the corrosion of in a single day breaking of formed barrier will be spread below paint, cause the flaking of steel part outside face and attack steel part, influences the steel part in-use performance.Trace it to its cause and be that they do not contain enough zinc the cathode protection layer is provided.
The purpose of this utility model aims to provide a kind of easy construction, antiseptic property is good, becoming rusty is difficult for the steel vessel with cathodic protection coatings and the member of diffusion transfer under coating.
The purpose of this utility model realizes as follows: a kind of steel vessel and member with cathodic protection coatings, it be is characterized in that having the cathodic protection coatings that contains zinc at its steel vessel and external surface of structural member coating by steel vessel and member.
Above-mentioned cathodic protection coatings is by the zinc powder that contains below the fineness 10 μ m; the organic solvent of granular synthetic resin and benzene class is prepared formed coating; drying and forming-film forms in addition after steel vessel and external surface of structural member are coated; its zinc powder: organic solvent: the proportioning of synthetic resin 2000: 480: 95, dry film coat thickness are more than the 100 μ m.
The content of zinc powder in dry film is more than 95% in the above-mentioned coating, the sacrificial anode that corrodes as protecting steel vessel and member.
Preceence of the present utility model is: coated workpiece avoids dismounting, makes simply easy construction.The antiseptic property height has improved abominable, the weather corrosion beharvior of anti-air environment of coated steel part, increases the service life, and the service life and the pot galvanize of its coating are suitable.It can also put on formerly the surface of pot galvanize and the supply reparation is carried out on the surface that hot galvanized layer is worn; new and old coating mix and; make it recover the cathode protection performance; the formed coating barrier of workpiece has been realized optimal fixation and sealing fully, and hard barrier has good resistibility to mechanical friction.
Below in conjunction with drawings and Examples in detail the utility model is described in detail.
Accompanying drawing 1 expression has the steel vessel scheme drawing of rich zinc cathodic protection coatings.
Accompanying drawing 2 expressions have the scheme drawing of the steel components of rich zinc cathodic protection coatings.
Has negative electrode conductive coating 2 at steel vessel or member 1 outside face; the coating of its coating 2 is made and earlier 5 parts of polystyrene synthetic resin is dissolved in 25 parts of organic solvents; dissolving fully after 24 hours; and then add 75 parts of zinc powders; disperseed 1 hour through the high degree of dispersion machine; promptly be formed in the coating that surface of the work can form conductive coating, this applying coating in the outside face of steel vessel 1 and member 1 drying film forming again, is formed negative electrode conductive protection coating 2.Can adopt the mode of brush spray and dip-coating to put on steel vessel 1 or the member 1.Its build is more than 100 μ m.
The coating of this conductive coating is at large structure, and as electric power tower, large-scale pipeline petrol storage tank, flow container, metal warehouse are achieved on hull, freight container, the metal construction antenna tower.Have good electric conductivity and weldability.
Claims (3)
1, a kind of steel vessel and member with cathodic protection coatings, it be is characterized in that having the cathodic protection coatings that contains zinc at its steel vessel and external surface of structural member coating by steel vessel and member.
2, steel vessel and the member with cathodic protection coatings according to claim 1; it is characterized in that; above-mentioned cathodic protection coatings is by the zinc powder that contains below the fineness 10 μ m; the organic solvent of granular synthetic resin and benzene class is prepared formed coating; drying and forming-film forms in addition after steel vessel and external surface of structural member are coated; its zinc powder: organic solvent: the proportioning of synthetic resin 2000: 480: 95, dry film coat thickness are more than the 100 μ m.
3, steel vessel and the member with cathodic protection coatings according to claim 1 is characterized in that, the content of zinc powder in dry film is more than 95% in the above-mentioned coating, the sacrificial anode that corrodes as protecting steel vessel and member.
