Oxit nhôm grit blasting is a type of abrasive blasting that uses aluminum oxide grit as the blasting media. Aluminum oxide is a hard, abrasive material that can be used to clean, etch, and prepare surfaces for painting, coating, or other finishing processes.

Aluminum oxide grit blasting is a versatile process that can be used on a wide variety of materials, bao gồm cả kim loại, gỗ, bê tông, và nhựa. It is often used to remove rust, sơn, or other contaminants from surfaces. It can also be used to etch or roughen surfaces to improve adhesion of coatings.

Aluminum oxide grit blasting is a safe and efficient process that can be done indoors or outdoors. It is also a relatively low-cost process.

The benefits of using aluminum oxide grit blasting

• It is a fast and efficient way to clean and prepare surfaces.
• It can be used on a wide variety of materials.
• It is a safe and environmentally friendly process.
• Đây là một quá trình có chi phí tương đối thấp.

Những hạn chế của việc sử dụng phương pháp phun cát oxit nhôm

• Nó có thể tạo ra bụi và khói, vì vậy điều quan trọng là phải thực hiện các biện pháp phòng ngừa an toàn.
• Nó có thể làm hỏng bề mặt mỏng manh.
• Nó không hiệu quả như một số loại phun mài mòn khác để loại bỏ các chất gây ô nhiễm nặng.

Tổng thể, Phun cát oxit nhôm là một quy trình linh hoạt và hiệu quả có thể được sử dụng để làm sạch, etch, và chuẩn bị bề mặt cho nhiều ứng dụng khác nhau.

Aluminum Oxide blast media Characteristics

1. Độ cứng: Aluminum oxide is known for its hardness, which allows it to cut through various materials quickly. It is often measured as one of the hardest materials used in blast media.
2. Angular Shape: The particles of aluminum oxide blast media are angular in shape, which makes them effective for removing contaminants and creating a textured surface on the material being blasted.
3. Reusable: One of the benefits of using aluminum oxide as a blast media is that it can be reused multiple times before it breaks down, making it a cost-effective choice for many applications.
4. Variety of Grades: Aluminum oxide blast media comes in various grades, which determine the size and shape of the particles. This allows for customization of the blasting process based on the specific needs of the project.

Aluminum Oxide blast media 80, 100, 120 sạn

1. 80 sạn
   • Coarseness: Relatively coarse
   • Các ứng dụng: Suitable for heavy material removal, such as stripping paint or rust from surfaces.
   • Surface Finish: Leaves a moderately rough surface finish, which can be suitable for applications where a textured surface is desired for better adhesion of coatings.
2. 100 sạn
   • Coarseness: Medium-coarse
   • Các ứng dụng: Used for surface preparation tasks like removing lighter layers of paint or smoothing rough surfaces.
   • Surface Finish: Produces a slightly smoother finish compared to 80 sạn, but still provides a good texture for paint adhesion.
3. 120 sạn
   • Coarseness: Fine
   • Các ứng dụng: Ideal for fine surface preparation tasks, such as creating a smooth surface before applying a finish or for cleaning more delicate materials.
   • Surface Finish: Leaves a smoother finish compared to 80 và 100 sạn, making it suitable for applications where a finer finish is desired.
