Scratch Resistance Testing of Tempered Glass-G-Tel

Scratch Resistance Testing of Tempered Glass Films for Smartphones and Its Importance

With the widespread use of smartphones, screen protectors have become an essential accessory in everyday life. Among them, tempered glass films are widely used due to their superior resistance to scratches and impacts. To ensure these tempered glass films effectively protect smartphone screens, scratch resistance testing plays a crucial role in evaluating their quality.

This article will explore the methods of scratch resistance testing for tempered glass films, its importance, and how G-Tel Glass Factory ensures product quality in this regard.

1. Definition and Importance of Scratch Resistance Testing

Scratch resistance testing simulates the contact between the smartphone screen surface and various materials (such as keys, coins, sand particles in pockets, etc.) to evaluate the glass film's ability to resist scratching and wear. This test is commonly measured using the friction coefficient or frictional force, with a lower friction coefficient indicating a smoother surface that is less likely to get scratched or worn down.

The performance of scratch resistance directly impacts the service life and protective ability of tempered glass films. If the film surface is prone to scratches or wear, it not only affects the screen's display quality but also diminishes the overall user experience. Therefore, scratch resistance testing is a key part of the quality control process during the production of tempered glass films.

2. Methods for Scratch Resistance Testing

(1) Abrasive Wear Testing Machine

A common method for scratch resistance testing involves using an abrasive wear testing machine, such as the Taber Abrasive Wear Tester. This device simulates the abrasion of various materials on the glass film surface, testing its ability to withstand wear and tear under specific conditions.

Testing Steps:

1. Fix the tempered glass film sample on the testing platform.
2. Choose different abrasive materials (such as sandpaper, steel brushes, etc.) as friction media.
3. Set the number of wear cycles and the applied pressure, then start the machine to perform the wear test.
4. After the test, examine the film’s surface for scratches, wear, or cracks.

(2) Manual Scratch Testing

Another common method is manual scratch testing, which is simpler and more suitable for small-scale quality control.

Testing Steps:

1. Use hard objects (such as coins or keys) to rub the surface of the tempered glass film.
2. Observe and record whether scratches or significant wear appear on the surface after the friction.
3. Assess the film's scratch resistance based on the depth and visibility of the scratches.

3. G-Tel Glass Factory’s Commitment to Scratch Resistance

G-Tel Glass Factory, a leading manufacturer of tempered glass films, is dedicated to delivering high-quality screen protectors. The company not only strictly follows international standards in its production processes but also constantly innovates to provide more durable products for consumers.

To ensure the scratch resistance of its tempered glass films, G-Tel Glass Factory employs advanced production techniques and utilizes precise testing equipment to ensure every tempered glass film undergoes rigorous scratch resistance testing. In G-Tel's factory, all tempered glass films undergo multiple rounds of testing, including abrasive wear tests and manual testing, to ensure that the film’s surface remains resistant to scratches under normal usage conditions.

Additionally, G-Tel Glass Factory uses an anti-fingerprint coating, which enhances the film's smoothness and resistance to dirt, further improving its scratch resistance. The company also uses hardness-enhancing treatments on the glass film surface to improve its hardness, making it more resistant to scratches from external objects.

4. Industry Standards for Scratch Resistance Testing

Different regions and brands of tempered glass films have varying scratch resistance performance requirements. Here are some common industry standards:

• ISO 15184: This international standard outlines testing methods for the scratch resistance and abrasion resistance of glass materials.
• JIS R 3202: The Japanese Industrial Standards (JIS) specify guidelines for scratch testing of glass materials.

These standards typically require tempered glass films to withstand a certain amount of friction without showing significant scratches or cracks. According to these standards, a tempered glass film's scratch resistance should be sufficient for typical daily use, where it will not be damaged by contact with hard objects.

5. Conclusion

Scratch resistance testing is a vital part of evaluating the quality of tempered glass films for smartphones. It directly affects the performance of the product and the user experience. By using abrasive wear testing machines and manual scratch testing, manufacturers can accurately assess the scratch resistance of the film and ensure it maintains its protective qualities during regular use.

G-Tel Glass Factory strictly adheres to quality control processes in its production of tempered glass films and constantly innovates to enhance the scratch resistance of its products. Whether through material selection, coating technologies, or testing procedures, G-Tel focuses on the user experience and strives to provide more durable and reliable products to the market.

Consumers choosing G-Tel tempered glass films not only benefit from high-quality screen protection but also enjoy superior scratch resistance, ensuring their smartphone screens remain clear and intact over time.
