Process of Steel Tube Shot Blasting Machine Treating Steel Surface Rust and Oxide

Process of Steel Tube Shot Blasting Machine Treating Steel Surface Rust and Oxide
How does the steel pipe shot blasting machine produced by Antai complete the disposal of rust and oxygenates? It uses a high-power motor to help the blades with the shot blaster rotate at high speed. Appearance of spit disposal. The three problems to be considered when using the steel tube shot blasting machine produced by Antai are: 1. The grade of rust removal. The starting process of ethylene, epoxy gas and phenolic anticorrosive paint sheets commonly used in steel pipes generally requires that the surface of the steel pipe reaches a white level (sa2.5) .The theory proves that it is suitable to use this derusting grade It can directly wash all the oxygenated skin, rust and other dirt of the snow. The depth of the anchor pattern is 40-100um, which can fully meet the requirements of the anti-corrosion house and the steel pipe. 2. The particle size and ratio of natural abrasives. In order to obtain a good uniform cleanliness and smoothness distribution, the particle size and ratio of natural abrasives are preset quite closely. If the finish is too large, the anti-corrosion layer will become thin. It is also possible that the anti-corrosion tail forms bubbles in the anti-corrosion process because the aiming pattern is too deep, thus affecting the function of the anti-corrosion layer. If the finish is too small, it will form a corrosion-resistant house and the strength and impact resistance will decrease. Regarding the internal pitting corrosion, not only rely on the superb impact of large particles of natural abrasives, but also rely on the small particles to fight the loss of the ablated products. The complete finishing effect is here. ), The application rate of natural abrasives can also be greatly increased. The particle size of the steel shot is 0.8 ~ 1.3 mm, and the particle size of the steel grit is 0.4- ~ 1.0 mm, with 0.5- ~ 1.0 mm as the main component. Sand pellets are 5 to 8 than usual. It should be noted that in practice, it is difficult to estimate the ideal ratio of steel grit and steel shot. The reason is that the hard and brittle steel grit has a higher crack rate than steel shot. To this end, the natural abrasives should be sampled and tested regularly during the operation. According to the particle size distribution, the new natural abrasives should be added to the steel pipe shot blasting derusting machine. Moreover, the new grinding is added moderately. 3. Natural abrasive of shot blasting machine. In order to achieve the ideal rust removal effect, we should select natural abrasives according to the hardness of the steel pipe surface and the original rust level, surface finish, coating type, etc. Regarding single-layer epoxy gas, two-layer or three-layer polyethylene coating, it is considered appropriate to use steel grit and steel shot doped natural abrasives to achieve the desired rust removal effect more easily. Steel shots have the effect of consolidating the steel surface, while steel grit has the effect of etching the steel surface. The above is the introduction of the rust, oxygenates and dirt on the surface of the steel pipe of the Antai steel pipe shot blasting machine. I hope it will be helpful to everyone.
