Abstract
The invention discloses an elastic polishing sand ball and a use method thereof, which are designed for completely clearing non-smelted micro-particles attached to the surface of a coating. An elastic rubber solid ball is arranged in the innermost space of the elastic polishing sand ball; a bottom rubber layer, an abrasive layer and a surface rubber layer are arranged on the solid ball outwardly in sequence. After an organic coating is sprayed to the inner wall of an oil pipe, the elastic polishing sand ball is driven by using a special clamp to do reciprocating motion, and the organic coating is ground and polished through contact pressure of the sand ball and the inner wall of the pipe; the elastic polishing sand ball can be replaced and used according to the specific condition of the organic coating from small diameter to big diameter or jumpily; before replacement of the sand ball and after grinding and polishing, the inner wall of the pipe is push-broomed by using a rubber cup. According to the elastic polishing sand ball, the organic coating on the inner wall of the oil pipe can be ground and polished to clear the non-smelted micro-particles attached to the surface of the coating, reduce the roughness of the surface of the coating and guarantee smooth and flat surface of the coating, so that the wear resistance performance of the coating is improved. The conventional fan blowing method can be substituted, and the elastic polishing sand ball a is convenient to use and is safe and environment-friendly.
Description
Technical field
The present invention relates to a kind of elastic polished sand ball and using method thereof, belong 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, namely utilizes high-pressure electrostatic electric field to order about electronegative paint particles and moves along the direction that electric field is contrary, make paint-absorbable in tube inner wall.When oil pipe shifts to an earlier date preheating more than 180 DEG C, paint particles can melt very soon, tiles, adheres to and solidifies.After paint solidification completes, tube inner wall is formed and has certain thickness organic coating, it can separate metal and Korrosionsmedium, plays effect that is anticorrosion and raising tubing life.
But after electrostatic spraying completes, due to part coatings particulate too near outer surface or be heated insufficient and cause part coatings not melt, 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 not molten particulate is solidificated in coating surface, is difficult to remove.Because oil pipe is elongated, be difficult to common sand paper the overall grinding and buffing carrying out inside coating.
Summary of the invention
The object of the present invention is to provide a kind of elastic polished sand ball and using method thereof, with the organic coating of grinding and buffing tube inner wall, thoroughly remove the not molten particulate of attachment.
Concrete technology contents of the present invention is as follows:
The the inside of this elastic polished sand ball is elastic caoutchouc medicine ball, is provided with primer layer, is provided with abrasive material outside primer layer, be provided with face glue-line outside abrasive material outside elastic caoutchouc medicine ball.
After being coated with organic coating to tube inner wall, elastic polished sand ball is driven to move reciprocatingly in pipe with special fixture, with the contact sanding and polishing organic coating of sand ball and inside pipe wall; The concrete condition according to organic coating can be followed from path to large footpath or jumpily change and use elastic polished sand ball; Before changing sand ball, push away with rubber cup and sweep inside pipe wall; After completing sanding and polishing, then push away with rubber cup and sweep inside pipe wall; Oil pipe is finally carried to put to finished product district.
This elastic polished sand ball can carry out sanding and polishing to the organic coating of tube inner wall, removes the not molten particulate being attached to coating surface, reduces its surface roughness, make its smooth surface smooth, thus improve its abrasion resistance properties.The present invention can substitute conventional blower blowing method, easy to use, safety and environmental protection.

Detailed description of the invention
Embodiment:
With reference to Fig. 1 and 2, embodiments of the invention are 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, is provided with primer layer 2, is provided with abrasive material 3 outside primer layer 2, be provided with face glue-line 4 outside abrasive material 3 outside elastic caoutchouc medicine ball 1.
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 coating 6, with bolt 8, this elastic polished sand ball is fixed in fixture 7, with connecting rod 9, fixture 7 and sand ball are clamp-oned oil pipe 5 again, and drive it to move reciprocatingly in pipe, utilize the contact sanding and polishing organic coating 6 of sand ball and inside pipe wall.The size that sand ball-type number presses abrasive material 3 diameter divides, and as 500#, 800#, 1000#, 1500# and 2000# etc., model is larger, and abrasive material 3 diameter is less.During sanding and polishing, the concrete condition according to organic coating 6 can be followed 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 the sand ball changing different model, push away the inside pipe wall after sweeping polishing with rubber cup, remove the not molten particulate or grit that fall, prevent the sand ball scratch-resistant coatings surface of rear replacing, affect the effect of grinding and buffing.After sanding and polishing completes, then push away with rubber cup and sweep twice, finally carry oil pipe 5 to finished product district to put.
