how to make the alloy tubing surface cleaner

How to make the alloy tubing surface cleaner? Today I will share some knowledge on alloy steel tube surface clean.

Descaling grade, the common used construction process of anticorrosion coating such as epoxy, vinyl, and phenol, generally requires the alloy tube surface reaching white. Through practice, it is proved that using the descaling grade can remove almost all of the scale, rust and other dirt to meet the requirements of the coating and the adhesion of the alloy tubing fully. And the spray de-rusting with low cost can be stable and reliable to make the quality reach white level conditions.

If you want to make the descaling achieve the ideal effect, it needs according to the hardness on the surface of the metal alloy steel tube, the original corrosion degree, the requirements of the surface roughness, coating types to choose abrasive such as single epoxy, two or three layers polyethylene coating. In order to achieve ideal cleaning effect, you need to adopt mixture of steel shot and steel grit abrasive. Because the steel grit has the effect of the reinforcement steel surface and steel shot has the impact of the etching on the steel surface.

It is very important for abrasive particle size and proportion of the design, if you want to get a better uniform distribution of cleanliness and roughness. Because of too big roughness, it is easy to cause coating becoming thin in the anchor lines in rush bum, meanwhile because too deep anchor lines can easily form bubbles in the process of corrosion and affects the performance of the anticorrosive coating seriously.

Before injection processing, remove the grease and scale on the surface of the seamless alloy steel tube, you can also use the furnace to heat the tube body preheating to 40 to 60 degrees Celsius to keep dry for the alloy tubing surface, because the alloy tubing surface is without greasy dirt. So it can enhance the cleaning effect. In addition, dry alloy tube surface is also conducive to separate of steel shot, rust and steel grit, and makes the alloy tubing surface much cleaner after descaling.
