Introduction to the correct storage methods for abrasive belts

+ 查看更多

With China's sustained and rapid economic growth and its establishment as a major manufacturing powerhouse, the importance of efficient, economical, and widely applicable abrasive belt grinding has gained significant attention across various industries. Many manufacturing enterprises are either already utilizing or preparing to adopt this advanced processing technology to enhance the quality and grade of their products. However, due to the relatively early stage of research and application of abrasive belt grinding in China, there is limited literature available regarding the storage and usage of abrasive belts. To optimize the advantages of abrasive belt grinding and ensure that abrasive belts perform at their best, let's delve into some key aspects of abrasive belt storage and usage.

I. Storage of Abrasive Belts

Proper storage of abrasive belts is crucial for their optimal use, especially for wider belts where the impact can be even more significant.

1. Temperature and Humidity Requirements

- Ideal Temperature: 18°C to 22°C

- Ideal Humidity: 40% to 65%

Abrasive belts should not be stored in places where there are significant fluctuations in temperature and humidity. High temperatures can lead to the aging of bonding agents, reducing the lifespan of the abrasive belt. Synthetic fiber-based belts, such as polyester cloth belts, are sensitive to cold and should not be stored in cold warehouses. Excessively high or low humidity can cause deformation in the belts, which in turn weakens the bonding strength of the abrasive layer. High humidity, in particular, can lead to severe consequences, making the belts susceptible to bending or wrinkling. Additionally, moisture can cause abrasives to adhere to the belt's surface, diminishing its lifespan. High temperatures and low humidity have a significant impact on paper-based belts, making them brittle and prone to breaking during use.

2. Storage Conditions

- The warehouse should be cool, dry, and well-ventilated.

- Belts should be placed on shelves, not directly on the floor.

- Maintain a distance of approximately 200 to 500mm between the shelves, ground, and walls to prevent interference with heat dissipation and drainage devices.

- Avoid opening the packaging of unused belts as much as possible.

- Do not stack heavy objects on top of belt packaging boxes to prevent creases and cracks.

II. Pre-processing of Abrasive Belts before Use

While proper storage is vital, the correct pre-processing of abrasive belts before use is equally crucial for optimal performance.

1. Hanging of Abrasive Belts

Before use, abrasive belts should be hung for a minimum of 2 to 5 days. This process aims to eliminate any curling that may have occurred due to packaging and to allow the belts to acclimate to the environment in which they will be used. The belts should be hung on pipes with a diameter of 100 to 200mm. The length of the pipe should be greater than the width of the belt to prevent it from slipping or creating bell-mouthed openings. The pipe should be level to avoid damaging the edges of the belt.

2. Visual Inspection

After hanging, a thorough visual quality inspection is necessary before use. Check for even and secure belt joints, as well as external defects like holes, clumps of sand, missing sand, adhesive spots, wrinkles, etc. Any minor cracks along the edges can be removed with a curved cut, as long as they don't affect usage.

Understanding the nuances of abrasive belt storage and pre-processing is essential for achieving optimal results in surface finishing. By following these guidelines, businesses can not only enhance the effectiveness of abrasive belt grinding but also prolong the lifespan of the belts, ensuring both customer satisfaction and cost-effectiveness in production.
