Description

Water sand blasting rust removing chamber for steel surface

Technical Field

Background

At present, the commonly used metal surface treatment method in China is a dry sand blasting method, and the traditional dry sand blasting method uses high-pressure gas produced by an air compressor as power, blows out quartz sand grinding materials at high speed through a sand pipe, and utilizes the beating and friction action of the grinding materials to remove rust. However, the traditional dry sand blasting method can generate a large amount of dust and rust dust when the abrasive material is blown out, and the dust is large and is not environment-friendly even if a sand blasting room is available, so that a novel water sand blasting rust removing device is popular in the market due to the strict environment protection in recent years. The abrasive is sucked by the negative pressure formed by high-pressure water during high-pressure injection of the water sand blasting gun head, and rust removal is performed by using the impact, impact and friction effects of the high-pressure water jet and the abrasive. However, the water-spraying sand-blasting rust-removing method needs a large sand-blasting room, uses a large amount of grinding materials, has high cost and is not suitable for large-scale use.
