300bar to 700bar Rust Paint Removal Water Sand Blaster

Rust Paint Revmoal Water Sand Blaster

There are currently two methods for metal surface treatment: chemical treatment and physical treatment. Chemical treatment is basically pickling. The working mechanism is to corrode the metal surface by a chemical reaction on the metal surface to achieve the purpose of treatment. However, the disadvantages of chemical treatment are large area, complicated process, and serious environmental pollution. Especially the sewage treatment after chemical treatment is difficult, and the investment is also large. Physical treatment can be roughly divided into shot blasting, air blasting, high-pressure water jet technology and other methods.

High-pressure water jet technology is divided into two parts: High pressure water blasting and high-pressure water & sand blasting. High pressure water treatment requires high pressure (> 700bar), large flow, and large drive power. High pressure water and sand blasting is relatively with low pressure(350-500bar), low power, high processing efficiency and cost saving.

The working principle of Rust Paint Removal Water Sand Blaster :

The high-pressure water produced by the high-pressure cleaner is sprayed from the sandblasting head through the high-pressure pipeline, and negative pressure is generated in the sandblasting chamber. The spare sand is passed into the sand pipe and the sand in the sand pipe Due to the pressure difference, it moves to the blasting cavity and mixes with high-pressure water in the blasting cavity, thereby accelerating the movement, spraying quickly, hitting the metal surface, and producing a certain cutting and grinding effect on the metal surface, making the metal surface non-destructive. The dirt, grease, rust, oxide scale, etc. on the body will be peeled off instantly, so that the metal surface will be exposed with metallic luster and achieve the desired surface effect.
