I. What is Nano Coating?
Nano coating refers to the introduction of nanomaterials (particle size 1-100nm) or the construction of nanostructures within a coating, endowing it with special functions that traditional coatings lack. The quantum size effect, surface effect, and macroscopic quantum tunneling effect of nanomaterials enable the coating to exhibit unique properties in optics, electricity, thermology, and mechanics.
II. Nano Self-Cleaning Coating
Based on two technical approaches:
– Superhydrophilic type (photocatalytic): Uses nano-TiO₂ as the core material. Under ultraviolet light, it generates photocatalytic reactions to decompose organic pollutants. Meanwhile, the surface becomes superhydrophilic, allowing rainwater to spread evenly and wash away stains. Suitable for glass curtain walls, solar panels, etc.
– Superhydrophobic type (lotus effect): Mimics the micro-nano composite structure of lotus leaves, with a contact angle >150°. Water droplets roll off in spherical shapes, carrying away dust. Suitable for building exteriors, bridges, transportation facilities, etc.
III. Nano Thermal Insulation Coating
Utilizes the selective reflection and absorption properties of materials such as nano antimony tin oxide (ATO) and nano indium tin oxide (ITO) against infrared rays to achieve transparent thermal insulation. Applied to architectural glass and automotive glass, it can reduce indoor temperatures by 5-8°C in summer and lower air conditioning energy consumption by 20-30%.
IV. Nano Anti-Corrosion Coating
Uses nano flake fillers (such as nano micaceous iron oxide, graphene, etc.) to create a “labyrinth effect” within the coating, significantly extending the penetration path of corrosive media and improving anti-corrosion performance by 3-5 times. Additionally, nanomaterials can fill micropores in the coating, enhancing its density and adhesion.
