Abstract
The utility model discloses an elastic polishing sand ball which is designed for thoroughly eliminating unfused particles adhering to the surface of a coating. An elastic rubber solid ball is arranged in the innermost position of the elastic polishing sand ball, a bottom adhesive layer, an abrasive material layer and a face adhesive layer are sequentially arranged on the solid ball from interior to exterior. After the inner wall of an oil pipe is coated with an organic coating, the elastic polishing sand ball is driven by a special clamp to make reciprocating motion in the pipe, and the organic coating is ground and polished through the contact pressure between the sand ball and the inner wall of the pipe. The elastic polishing sand ball can be replaced and used from the small diameter to the large diameter or in a jumpy mode according to specific conditions of the organic coating. Before the sand ball is replaced and the grinding and polishing is performed, the inner wall of the pipe needs to be swept in a pushing mode through a rubber leather cup. With the polishing sand ball, the organic coating of the inner wall of the oil pipe can be ground and polished, the unfused particles adhering to the surface of the coating can be eliminated, the surface roughness of the organic coating is reduced, the surface of the organic coating is made smooth and flat, and thus the abrasion resistance of the organic coating is improved. The elastic polishing sand ball can replace a conventional fan blow-sweeping method and is convenient to use, safe and environmentally friendly.
Description
Technical field
The utility model relates to a kind of elastic polished sand ball and using method thereof, belongs to steel pipe internal corrosion prevention technology field.
Background technology
In Oil/gas Well is produced, tube inner wall contact corrosion medium, is easily corroded.The anti-corrosion method of tube inner wall is a lot, and one of the most frequently used method is electrostatic spraying organic coating, utilizes high-pressure electrostatic electric field to order about electronegative paint particles and moves along the contrary direction of electric field, makes coating be adsorbed in tube inner wall.In the situation that oil pipe shifts to an earlier date preheating over 180 ℃, paint particles can melt very soon, tiles, adheres to and solidify.After paint solidification completes, on tube inner wall, form and have certain thickness organic coating, it can separate metal and Korrosionsmedium, plays effect anticorrosion and that improve tubing life.
But, after electrostatic spraying completes, because part coatings particulate is too not molten near outer surface or insufficient part coatings that causes that is heated, cause coating surface rough, roughness increases.Existing treatment measures normally purge with blower fan, pollute the environment, and worsen workman's working condition, and some molten particulate is solidificated in coating surface, very difficult removing.Because oil pipe is elongated, with common sand paper, be difficult to carry out the whole grinding and buffing of inside coating.
Summary of the invention
The purpose of this utility model is to provide a kind of elastic polished sand ball, with the organic coating of grinding and buffing tube inner wall, thoroughly removes the not molten particulate adhering to.
Concrete technology contents of the present utility model is as follows:
The the inside of this elastic polished sand ball be elastic caoutchouc medicine ball, and elastic caoutchouc medicine ball outside is provided with primer layer, and primer layer outside is provided with abrasive material, is provided with face glue-line outside abrasive material.
This elastic polished sand ball can carry out sanding and polishing to the organic coating of tube inner wall, removes the not molten particulate that is attached to coating surface, reduces its surface roughness, makes its smooth surface smooth, thereby improves its abrasion resistance properties.The utility model can substitute conventional blower fan blowing method, easy to use, safety and environmental protection.

Fig. 2 is elastic polished sand ball work schematic diagram.
The specific embodiment
Embodiment:
With reference to Fig. 1 and 2, embodiment of the present utility model is further illustrated:
This elastic polished sand ball mainly comprises elastic caoutchouc medicine ball 1, primer layer 2, abrasive material 3 and face glue 4;
The the inside of this elastic polished sand ball is elastic caoutchouc medicine ball 1, and elastic caoutchouc medicine ball 1 outside is provided with primer layer 2, and primer layer 2 outsides are provided with abrasive material 3, and abrasive material 3 outsides are provided with face glue-line 4.
The face glue-line 4 of this elastic polished sand ball is mixed by binding agent, solvent and filler.
The using method of this elastic polished sand ball is as follows:
After oil pipe 5 inner-wall spraying organic coatings 6, with bolt 8, the elastic polished sand ball of basis is fixed in fixture 7, with connecting rod 9, fixture 7 and sand ball are clamp-oned to oil pipe 5 again, and drive it in pipe, to move reciprocatingly, utilize the contact sanding and polishing organic coating 6 of sand ball and inside pipe wall.The size of the sand ball model rubbing bed of material 3 diameters is divided, and as 500#, 800#, 1000#, 1500# and 2000# etc., model is larger, and abrasive material 3 diameters are less.During sanding and polishing, can follow concrete condition according to organic coating 6 from path to large footpath or jumpily change and use sand ball, the sand ball sanding and polishing of each model two to three times.Before changing the sand ball of different model, push away the inside pipe wall of sweeping after polishing with rubber cup, remove the not molten particulate or the grit that fall, prevent that the sand ball of rear replacing from scratching coating surface, affect the effect of grinding and buffing.After sanding and polishing completes, then push away and sweep twice with rubber cup, finally carry oil pipe 5 to finished product district to put.
