Abstract
A radiator with an anticorrosive protection layer is disclosed, wherein an anticorrosive layer of an amorphous state is evenly coated on the wall of the radiator; the anticorrosive layer is arranged on the inner wall or the outer wall of the radiator and is made up of ingredient of lamellar aluminum powder, zinc powder and chromate and so on; the thickness of the anticorrosive layer is generally no more than 20 microns. The utility model has the advantages that the anticorrosive effect is apparent and the service life of the radiator is long in that lamellar aluminum powder and zinc powder are used as the anticathode in the coating of the inner wall of the radiator, and the coated layer of amorphous state is compact, thus the connection between the coated layer and the wall surface is close; the adhesive force is great and the thickness is appropriate.
Description
Technical field
The utility model relate to a kind of can erosion-resisting radiator, especially a kind of radiator that has corrosion protective covering.Belong to mechanical manufacturing field.
Background technology:
Because the radiator long period of soaking is in water, when water quality is defective, the corrosion that some materials in the water are difficult to stop to its inwall inevitably, this has had a strong impact on the service life of radiator.Therefore have employing that the magnesium rod is set in radiator, the iron and steel of radiator is as negative electrode, with the practice of sacrificial anode, in the hope of in and ion in the water or ion cluster etc., make the water of system be alkalescence, thereby reach erosion-resisting purpose.But because the service life of magnesium rod is limited, the time one is long, just must change the magnesium rod, and not only maintenance work is numerous and diverse, and directly brings many inconvenience to the user.Have, the magnesium rod is done the position at place again, and electric-field intensity is strong than other places, must cause phenomenons such as corrosion resistance is inhomogeneous.
Summary of the invention:
The purpose of this utility model is to provide a kind of radiator that has corrosion protective covering at the deficiency of prior art, and the resistance to corrosion of radiator is strong, and quality is higher, long service life.
The utility model is achieved through the following technical solutions above-mentioned purpose for this reason: a kind of radiator that has corrosion protective covering evenly is coated with the amorphous state anticorrosive coat with the anode material on the wall that wherein dispels the heat.Radiator inwall or outer wall are equipped with anticorrosive coat.
Wherein, anticorrosive coat is the coating based on flake aluminum and zinc powder and chromate, and anticorrosive coat thickness generally is no more than 20 microns.
According to the technical solution of the utility model analysis as can be known; because the corrosion-inhibiting coating that radiator inwall coating is made up of flake aluminum and zinc powder and chromate; aluminum and zinc itself is sacrificed as anode; can play effective cathodic protection effect to steel; the amorphous state coating structure closely and wall be connected firmly; anticorrosive coat thickness is suitable, so anti-corrosion effects is obvious, the radiator long service life.
Description of drawings:
Fig. 1 is a kind of embodiment part section structural representation of the present utility model.
The specific embodiment:
Below in conjunction with accompanying drawing and specific embodiment the utility model is described in further detail.
Referring to Fig. 1, the utility model is a kind of radiator 1 that has corrosion protective covering.Particularly, in the present embodiment, be the amorphous anticorrosive coat 3 that on radiator inwall 2, evenly is coated with the anode material.Wherein, anticorrosive coat 3 is the coating of flake aluminum and zinc powder and chromate, and anticorrosive coat 3 thickness are several to tens microns, for example generally are no more than 20 microns.Adhering to of anticorrosive coat 3 can form thin film by spray, brush, immersion or forced circulation on the wall 2 of radiator, through the above hot setting of 300 degree, behind generation chemistry and the physical reactions, finally form wear-resisting, corrosion resistant coating 3 on wall 2.This coating 3 belongs to amorphous structure, Wu Jinjie, is difficult to pass coating etch matrix in conjunction with even compact, corrosive deposit, has played good antisepsis for the inwall 2 of steel radiator 1.And because this coating 3 be the anode material, even so radiator inwall 2 surfaces when holiday or cut occurring, still can keep good protective effect.
Certainly, for ensureing the antiseptic power or the anti-wear performance of radiator 1 outer wall, also can on the outer wall of radiator 1, set up this anticorrosive coat.
Owing to adhere to the flake aluminum that is provided with the anode material and the amorphous state anticorrosive coat of compositions such as zinc powder and chromate on radiator inwall or the outer wall, the anti-corrosion layer structure densification, strong adhesion, thickness is suitable, therefore anti-corrosion effects is obvious, the radiator long service life greatly reduces the workload of safeguarding in the use.
It should be noted last that, above embodiment is only unrestricted in order to explanation the utility model, although the utility model is had been described in detail with reference to preferred embodiment, those of ordinary skill in the art is to be understood that, can make amendment or be equal to replacement the utility model, and not breaking away from spirit and scope of the present utility model, it all should be encompassed in the middle of the claim scope of the present utility model.
