What are the Mainstream Grinding and Polishing Technologies in Our Country?

+ 查看更多

The market for grinding and polishing products in our country offers a wide variety of options. From a technical standpoint, we can primarily classify them into three categories. These three mainstream grinding and polishing technologies in our country each have their unique characteristics and applications. Understanding these technologies is crucial for selecting the right method that meets specific requirements and achieves optimal results.

1. Physical Grinding:

This technology utilizes irregular rhomboid-shaped abrasive particles of varying sizes. It delivers excellent results in terms of oxidation removal and scratch elimination. However, the use of angular coarse abrasives can sometimes result in secondary fine scratches. To address this, multiple rounds of grinding with finer abrasives are necessary, making the process complex and potentially damaging to the paint surface. Over-reliance on this type of grinding technology can lead to a dependency on polishing and waxing, causing the clear coat layer to become thinner over time and diminishing the original paint's luster.

2. Physical Grinding with Coating:

After the initial coarse scratches are removed, this technique produces a glossy effect. However, under sunlight, fine micro-scratches become visible due to the filling of some scratches with wax or resin components, rather than their complete removal. Excessive oiliness and the movement pattern of polishing pads can create a swirling effect. This polishing method is prone to the reappearance of scratches after a few washes, making it misleading and frustrating for automotive technicians unaware of its limitations.

3. Delayed Fracture Polishing Technology:

This advanced and relatively rare grinding technique involves the use of spherical abrasive particles that do not cause secondary scratching. The polishing process maintains a relatively low temperature on the paint surface. When the high-speed rotation of the polishing pad generates heat with the abrasive particles, they instantaneously fracture into finer particles. This allows for effective deep-level polishing without the need for multiple steps. With each polishing session, the paint surface becomes progressively brighter and more lustrous. This technology ensures both effective results and minimizes damage to the paint surface (although some degree of damage is inevitable during polishing). Furthermore, the polishing compounds used in this technique do not contain wax or resin components, resulting in a deep and glossy appearance that highlights the natural luster of the original paint.

Understanding the various grinding and polishing technologies available in our country is crucial for achieving desired results while minimizing potential damage to the paint surface. Each technology has its advantages and limitations. Physical grinding offers good scratch removal but requires careful consideration to avoid excessive damage. Physical grinding with a coating provides a glossy finish but may be prone to swirl marks. Delayed fracture polishing technology represents an advanced method that ensures effective results and minimizes damage to the paint surface. By choosing the appropriate technology based on specific requirements, automotive technicians can achieve superior polishing results that enhance the overall appearance and durability of the paintwork.
