The relationship and difference between Dalian sandblasting and rust removal technology

Dalian sandblasting is a common surface treatment method with advantages such as environmental protection, strong adaptability, and significant effects. It is widely used in industries such as metal, plastic, and glass, which can improve the surface quality and aesthetics of products. However, when using sandblasting, we must pay attention to safety and take corresponding protective measures to ensure the safety and environmental hygiene of the workplace.

The principle of sandblasting processing is to use high-speed airflow to spray sand particles onto the surface of the treated object, thereby grinding away impurities and defective layers on the surface. The commonly used sandblasting machine is a pressure type sandblasting machine, which uses high-pressure gas to bring sand particles into the spray gun and then spray them out through the nozzle. After the sand particles are sprayed out, they rub against the surface of the treated object to remove impurities and defective layers from the surface. Sandblasting does not produce chemical reactions during surface treatment, therefore it will not cause significant changes to the structure and properties of the material.

The relationship and difference between Dalian sandblasting and rust removal technology

1、 Definition

Sandblasting: Sandblasting is a process that uses wind pressure to spray abrasive particles at high speeds, and through friction with objects, it achieves surface polishing, decontamination, or decorative treatment.

Rust removal technology: Rust removal technology refers to the technology of removing metal surface rust, dirt, oxide layers, etc. through various means (such as mechanical rust removal, chemical rust removal, electrolytic rust removal, etc.).

2、 Principle

Sandblasting processing: Sandblasting processing uses wind power to spray abrasive onto the surface of an object, forming a high-speed sandblasting flow. High speed collisions cause surface dirt, oxide layers, and residual carbon to be impacted, broken, and detached, thereby achieving the effect of polishing and cleaning.

Rust removal technology: Rust removal technology can adopt different methods, mainly including mechanical rust removal, chemical rust removal, electrolytic rust removal, sandblasting rust removal, etc. The principles of these methods vary, but overall, they all restore the smoothness and stability of the metal surface by destroying or decomposing the rust layer, oxide film, and attachments, removing or reducing them.

3、 Application scope

Sandblasting: Sandblasting is usually suitable for surface treatment and decorative processing of metal and non-metallic materials. Common applications include vehicle repair, steel structure anti-corrosion, aluminum alloy surface treatment, carving, decoration, etc.

Rust removal technology: Rust removal technology is mainly applied to the surface rust, oxidation, and removal of desorbed substances of metal materials. Common application areas include anti-corrosion and rust removal of metal products such as ships, bridges, steel structures, pipelines, automobiles, furniture, etc.

The application of sandblasting processing is very extensive. In the metal processing industry, sandblasting can be used to remove surface dirt such as welding slag, oxide layer, and rust, in order to improve the surface quality and appearance of metal products. In the plastic processing industry, sandblasting can be used to trim burrs and unevenness on plastic surfaces, improving the quality and aesthetics of plastic products. In the glass processing industry, sandblasting can be used to manufacture glassware, achieving the desired effect and texture on the glass surface through sandblasting.

The sand particles used in sandblasting processing are generally silicon sand, glass beads, corundum sand, iron filings, and other materials, and their selection is determined based on the material, requirements, and processing effect of the workpiece.
