The Three Most Mainstream Grinding and Polishing Technologies in China
Release Date：2023-07-05 10:54
The market in China offers a wide range of grinding and polishing products with various techniques and principles. These products can be primarily categorized into three types based on their technological principles. In this article, we will explore these three mainstream grinding and polishing technologies, their advantages, and their considerations.
1. Physical Grinding:
The first type is physical grinding, where the abrasive particles are irregularly shaped with varying levels of coarseness. This type of grinding is highly effective in removing oxidation and scratches, making it a popular choice in the market. However, abrasive particles with sharp edges can sometimes cause secondary micro-scratches. In such cases, a finer-grade abrasive is required for subsequent grinding, resulting in a more complex process and potential damage to the paint surface.
2. Physical + Covering Polishing:
The second type combines physical grinding with a covering polishing approach. Immediately after the coarse scratches are polished, the surface appears glossy. However, under sunlight, there may be visible fine swirl marks. This occurs because some of the scratches are filled with wax or resin oil-based components instead of being completely removed. Excessive oiliness can create polishing fiber trail marks, resulting in swirl marks.
3. Advanced Delayed Breakdown Polishing:
The third type is a relatively rare and advanced grinding technology known as delayed breakdown polishing. In this technique, the abrasive particles are spherical, resembling glass beads. This technology eliminates the problem of secondary micro-scratches and keeps the paint surface temperature relatively low. As the polishing fibers rotate at high speed and generate a certain level of heat with the abrasive particles, the particles instantly break down into finer particles. This enables effective deep-level polishing, achieving a high level of gloss in a single step. This advanced polishing technology guarantees desired results while minimizing potential damage to the paint surface.
How to Choose High-Quality Grinding and Polishing Products:
When selecting high-quality grinding and polishing products for your specific needs, consider the following two recommendations:
1. Ensure Complete Removal of Scratches and Oxidation:
Opt for abrasive particles that thoroughly remove scratches and oxidation while minimizing damage to the paint surface. Depending on the condition of the paint surface, select the appropriate coarseness of the abrasive particles and consider localized sanding using sandpaper whenever possible.
2. Avoid Oil-Based Covering Products:
Avoid using products that contain wax or resin oil-based components solely for achieving surface effects. These products may mask scratches rather than remove them completely. It is advisable to choose products that focus on the actual polishing process rather than relying on covering functions.
China offers a wide range of grinding and polishing products with different techniques and principles. Understanding the three mainstream grinding and polishing technologies helps in making informed decisions when selecting high-quality products. Physical grinding, physical + covering polishing, and advanced delayed breakdown polishing each have their advantages and considerations.
