What is the principle behind marble protective film

1. Material Barrier Formation: 

The core substrate of marble protective film is mostly a dense polymer material, which inherently possesses excellent barrier properties. When the protective film is applied to the marble surface, it forms a continuous and seamless thin film barrier, effectively preventing external pollutants such as moisture, oil, and dust from penetrating into the marble. Marble's microporous structure easily adsorbs various impurities, and the protective film's barrier effect cuts off the contact path between pollutants and the marble surface, preventing impurities from entering the stone through the micropores and causing discoloration, pollution, and other problems, thus protecting the cleanliness and appearance of the marble from the source.

2. Physical Protection Against External Damage: 

The protective film provides direct buffering and protection for marble at a physical level. In daily use, the marble surface is easily affected by external forces such as scratches, impacts, and friction. The protective film, with its inherent toughness and strength, can absorb these impacts, reducing direct wear from sharp objects on the marble surface. Meanwhile, during handling and construction, the protective film isolates the marble from direct contact with other objects, preventing scratches, chips, and other damage caused by collisions, maintaining the smoothness and integrity of the marble surface, and reducing the difficulty and cost of later repairs.

3. Molecular Adhesion Enhances Adhesion Stability: 

High-quality marble protective films are coated with a special adhesive layer on the back. The molecules in this coating generate a weak adhesion force between themselves and the molecules on the marble surface. This adhesion is not a strong bond, but rather a close adhesion between molecules, preventing the protective film from peeling or falling off. Furthermore, this adhesion method leaves no sticky residue on the marble surface, ensuring a clean surface when the protective film is removed later, avoiding secondary cleaning problems caused by adhesive residue, thus balancing adhesion stability and ease of use.

4. Environmental Adaptability Delays Aging and Deterioration: 

Over long-term use, marble is susceptible to environmental factors such as ultraviolet radiation, temperature changes, and humidity fluctuations, leading to surface aging, loss of luster, and structural loosening. Marble protective films have excellent environmental adaptability. Some products also contain ingredients that resist ultraviolet rays and temperature changes, which can block direct ultraviolet radiation from reaching the marble and reduce the damage to the internal structure of the stone caused by drastic temperature and humidity changes. By isolating these adverse environmental factors, the protective film can slow down the aging process of marble, extending its service life and aesthetic lifespan.
