The **anti-corrosion back paint** on the back of Himei waterproof tiles has multiple advantages, which can significantly improve the durability and applicability of tiles. The following are the specific advantages and mechanisms of action:
1. Moisture-proof and anti-corrosion, extending service life
– Isolate moisture penetration: The back paint forms a dense protective layer to prevent rainwater and condensation water from penetrating into the tile substrate (such as metal, fiber-reinforced materials, etc.), avoiding metal rust or wooden substrate rot.
– Chemical corrosion resistance: In industrial areas, coastal areas and other environments, the back paint can resist the erosion of corrosive substances such as acid rain, salt spray, and pollutants on the substrate, reducing material loss.
2. Improve substrate stability
– Reduce deformation and cracking: By blocking moisture and corrosive media, the substrate is prevented from expanding, contracting and weakening due to repeated dry-wet cycles or chemical reactions, and the shape of the tile is maintained stable.
– Enhanced freeze-thaw resistance: In cold areas, the back paint can reduce the risk of damage to the substrate due to freezing and expansion after moisture infiltration.
3. Improved auxiliary functionality
– Improved adhesion: Some anti-corrosion back paints can be used as bonding layers to enhance the adhesion between tiles and roof substrates (such as wood boards and concrete), and improve the stability of the overall system.
– Heat and sound insulation: Some back paints contain heat insulation fillers or closed-cell structures, which can reduce heat transfer or reduce raindrop noise, thereby improving building comfort.
– Fire retardant (some products): Specially formulated back paints can delay the spread of fire and improve the fire resistance level of roofs.
5. Adapt to complex environments
– Coping with extreme climates: In areas with high temperature, high humidity, heavy rain and snow, or strong ultraviolet rays, the back paint and the tile surface protective layer form a “double-sided barrier” to synergistically resist environmental pressure and expand the scope of application of waterproof tiles.
Summary of advantages
The anti-corrosion back paint provides all-round protection for waterproof tiles by ** isolating corrosive media + stabilizing the substrate structure + strengthening ** with additional functions. Its core values include:
– Extend life: reduce corrosion damage to the substrate and reduce replacement frequency;
– Reduce maintenance costs: avoid leakage repairs caused by back corrosion;
– Broaden application scenarios: suitable for harsh environments such as chemical plants, coastal buildings, and high humidity areas.
This design enables waterproof tiles to maintain high performance under complex working conditions, making it a reliable choice for modern building waterproofing.
