Categories and Safety Measures of Sandblasting Rooms

Sandblasting room is an important equipment for surface treatment and coating. Depending on its use and characteristics, sandblasting rooms can be divided into several different categories. This article will discuss the classification of sandblasting rooms and explore the application and features of various types in industrial production.

Classification of Sandblasting Rooms

By Sandblasting Method

Sandblasting rooms can be divided into pressure-type sandblasting rooms and suction-type sandblasting rooms based on the different sandblasting methods.

Pressure-type sandblasting rooms use high-pressure air to spray abrasives onto the surface of the workpiece for cleaning and treatment. This method has high sandblasting efficiency and is suitable for larger workpieces and large surface area treatment.

Suction-type sandblasting rooms, on the other hand, use a negative pressure system to draw abrasives into the sandblasting gun, then spray them onto the workpiece surface. They are suitable for small parts and fine processing.

By Sandblasting Material

Sandblasting rooms can be divided into sandstone sandblasting rooms, glass bead sandblasting rooms, and steel shot sandblasting rooms based on the different sandblasting materials.

Sandstone sandblasting rooms are suitable for rough surface treatment and oxide scale removal from workpieces. Glass bead sandblasting rooms are suitable for smooth surface treatment and stain removal, while steel shot sandblasting rooms are suitable for surface strengthening and slag removal from workpieces.

By Structural Form

Sandblasting rooms can be divided into open-type and closed-type sandblasting rooms based on different structural forms.

Open-type sandblasting rooms are usually used for surface treatment of workpieces. They are easy to operate but have serious dust pollution. Closed-type sandblasting rooms are suitable for fine processing of small workpieces, effectively controlling dust pollution and improving the cleanliness of the working environment.

By Application Field

Sandblasting rooms can be divided into automotive sandblasting rooms, aerospace sandblasting rooms, and furniture sandblasting rooms based on different application fields.

Automotive sandblasting rooms are mainly used for surface treatment and painting of automotive parts. Aerospace sandblasting rooms are used for surface treatment and corrosion prevention of aircraft and rockets. Furniture sandblasting rooms are used for surface treatment and decoration of wood in furniture manufacturing.

Sandblasting Room Safety Guide

Sandblasting rooms are equipment used for cleaning and treating workpiece surfaces. However, there are certain safety risks during their use. Therefore, it is crucial to take appropriate safety measures.

Wear Appropriate Personal Protective Equipment

Respiratory Protection

Sandblasting produces a lot of dust, so it is necessary to wear a suitable respiratory mask, preferably with particulate filtration function, such as an N95 mask or higher-level protective equipment. It is recommended to use an air-supplied respirator to ensure operators do not inhale harmful dust.

Eye and Face Protection

Goggles or full face shields are essential to prevent particles or debris from causing eye injuries.

Protective Clothing and Gloves: Wear protective clothing, safety shoes, and durable gloves to avoid skin injury from abrasive particles.

Regular Maintenance of Equipment

Inspection of Sandblasting Equipment

Regularly check if the sandblasting equipment has air leaks, damage, or blockages. Ensure the equipment operates normally to reduce the possibility of accidents.

Cleaning Equipment

Maintenance and cleaning of equipment are equally important. Remove accumulated dust, especially in the air filters and ventilation system.

In summary, sandblasting rooms are important surface treatment equipment that have wide industrial applications. Based on the characteristics of different sandblasting methods, materials, structural forms, and application fields, sandblasting rooms can be classified in various ways. 

Different types of sandblasting rooms play different roles in industrial production, meeting the surface treatment needs of various industries, and enhancing production efficiency and product quality. At the same time, using sandblasting rooms involves certain risks, so proper safety measures should be taken.
