Abstract
The invention relates to a surface protective device for a sucker rod and a protective method, which belongs to the field of surface protection of metal materials. According to the invention, the sucker rod is soaked in a water-soluble paint as a cathode, and an anode which corresponds to the cathode is additionally arranged. Low voltage direct current is introduced between the cathode and the anode, so that resin with positive charge and color filling particles in the water-soluble paint are uniformly deposited on the surface of the sucker rod by means of physical and chemical effect generated by an electric field so as to form a water-fast paint film. The surface of the sucker rod soaked has the characteristics of uniform paint film, strong adhesion, corrosion resistance (salt spray test reaches 1000 h which is more than 15 times of common asphalt paints) and the like; the phenomena of paint flowing and hanging are thoroughly eliminated; and the product quality is greatly ensured.
Description
Technical field
The present invention relates to a kind of sucker rod surfacecti proteon device and means of defence, belong to metal material surface protection field.
Background technology
At present, although the process for protecting surface form of domestic sucker rod is different, but all be that sucker rod is immersed in the bituminous varnish on principle, bituminous varnish is attached on the sucker rod surface, this kind processing method has the following disadvantages: 1) paint film adhesion is poor, through expose to the weather pull-away, produce serious corrosion when depositing in the open; 2) film thickness is uneven, and sucker rod first half paint film is thin, and Lower Half is thick, even produces more serious lacquer stream, lacquer extension phenomenon, can not satisfy well the sucker rod service requirements; 3) protective paint of selecting is bituminous varnish, the long or transportation in period of storage, the relatively poor place (such as sea transport, outdoor storage, oil field, seashore etc.) of storage environmental condition, and its solidity to corrosion and weathering resistance are relatively poor.
Technology contents
The present invention aims to provide a kind of solidity to corrosion and the weathering resistance that can improve sucker rod, satisfies sucker rod surfacecti proteon device and the process for protecting surface of sucker rod product surface quality and actual operation requirements.
Technical solution
A kind of sucker rod surfacecti proteon device, comprise: sucker rod, stainless steel tank, low-voltage dc power supply, also comprise the Metallic rod hanger, Metallic rod hanger one end is connected with low-voltage dc power supply, and low-voltage dc power supply is connected with anode electrode by wire, the Metallic rod hanger the other end is connected with sucker rod, the sucker rod two ends are provided with the screw thread protective cap, are provided with in the water soluble paint in the stainless steel tank, and sucker rod places water soluble paint.
Surfacecti proteon of the present invention is as follows: in advance sucker rod carried out cleaning surfaces and processes, and oil removing, rust cleaning, phosphatization, and plastic protective cap is installed in screw thread position, two ends; Then sucker rod is put into the stainless steel tank that fills water soluble paint and kept 2 ~ 3min, logical 40 ~ 70V low voltage voltage between anode electrode 6 and negative electrode, the physics chemical action that relies on electric field to produce, making under the effect of positively charged resin in the water soluble paint 5 and color filler grain electric field to negative electrode is the sucker rod directional migration, separate out equably and deposit on the surface that is solidificated in sucker rod, finally in the application length range, form one deck continuously, evenly, fine and close and water-fast black gray expandable coating layer paint film, film thickness is 20 ~ 30 μ m.
The present invention is immersed in the water soluble paint sucker rod as negative electrode, other establishes an anode corresponding with it, at the logical low-voltage DC of two interpolars, the physics chemical action and electrochemical reaction process (heteropole is inhaled mutually) that rely on electric field to produce, make charged resin and color filler grain directional migration in the water soluble paint, separated out equably and deposited on the surface that is solidificated in sucker rod (negative electrode), finally form one deck continuously, evenly, fine and close and water-fast paint film.
Description of drawings
Fig. 1 is sucker rod structural representation of the present invention;
Fig. 2 is structural representation of the present invention.
Embodiment
With reference to Fig. 2; the present invention is immersed in the water soluble paint 5 in the stainless steel tank 4 sucker rod 1 as negative electrode; Metallic rod hanger 7 one ends are connected with anode electrode 6 by low-voltage dc power supply 8; Metallic rod hanger 7 the other ends are connected with sucker rod 1; for the screw thread position that makes sucker rod 1 two ends is not coated, the plastic protective cap 3 of seal protection effect has been housed at the screw thread position of sucker rod 1.
Logical 40 ~ 70V low voltage voltage between anode electrode 6 and negative electrode, the physics chemical action that relies on electric field to produce, make under the effect of positively charged resin in the water soluble paint 5 and color filler grain electric field to negative electrode (sucker rod 1) directional migration, separate out equably and deposit on the surface that is solidificated in sucker rod 1, finally in the application length range, form one deck continuous, evenly, fine and close and water-fast black gray expandable coating layer paint film 2, film thickness is 20 ~ 30 μ m, after the dip-coating, it is even that sucker rod 1 surface has paint film, strong adhesion, it is corrosion-resistant that (salt-fog resistant test can reach 1000 hours, more than 15 times of common impregnate with bitumen lacquer) characteristics, and thoroughly eliminated lacquer stream, lacquer is hung phenomenon, greatly guarantees quality product.
Use processing method of the present invention that pony rod is carried out specimen test, the result shows: film thickness 25 μ m; Its acid resistance and alkali resistance all reach 24h without unusually; Petrol-resistance reaches 24h without unusually; Salt fog resistance reaches the 1000h plane without foaming, non-corroding, is more than 15 times of paint film of plain asphalt lacquer.
