Technical Analysis and Market Application of Adding Antibacterial and Antifungal Agents to Artificial Boards
I. Technical Principles and Core Functions
Antibacterial and antifungal agents achieve protective functions by destroying the cell structure of microorganisms and inhibiting their metabolic reproduction. In view of the characteristic that artificial boards are prone to erosion by molds such as Aspergillus Niger and Penicillium orange, modern technology adopts a multi-component compound system:
Nano-silver/copper ion technology: By ion penetration to destroy the membrane structure of microorganisms, it achieves long-lasting antibacterial effects (for example, the anti-mold period of Paiyangshan's "Green Shield Series" exceeds 5 years).
Organic-inorganic composite system: By integrating nano-titanium dioxide photocatalysis, quaternary ammonium salt modified resin, etc., the broad-spectrum antibacterial property is enhanced (for instance, the antibacterial efficiency of Dingfeng Wood Industry's "Jian Dun Series" under ultraviolet irradiation is increased by 40%).
Structural optimization technology: By controlling the water absorption rate of the board (for example, the water absorption rate of Penghong board ≤8%) and the deviation of cross-sectional density (≤3%), the environment for microbial breeding is reduced.
Ii. Mainstream Technical Paths and Product Types
Inorganic antibacterial system
Nano zinc oxide: Good transparency, suitable for light-colored boards (such as melamine decorative panels).
Silver-loaded zirconium phosphate: High-temperature resistant, long-lasting slow-release, suitable for medical-grade scenarios (for example, Penghong's "Hongkang series" particle boards have been certified by tertiary hospitals).
Copper-based antibacterial agent: Combined with eucalyptus fiber composite matrix, it enhances the stability of the substrate (patented technology of Paiyangshan).
Organic composite system
All-organic water-based fungicide: Free of heavy metals, with heat resistance up to 200℃, suitable for various scenarios such as wood, glue, and leather.
Quaternary ammonium salt-modified resin: It can kill bacteria rapidly but has poor weather resistance and needs to be compounded with other technologies (such as double-chain quaternary ammonium salts to enhance adsorption through molecular structure optimization).
Microcapsule sustained-release technology: Continuously releases natural components such as tea tree essential oil, extending the anti-mold validity period to 7 years.
Iii. Application Scenarios and Performance Standards
Home furnishing field
Kitchen/Bathroom: Antibacterial and anti-mold decorative panels inhibit Escherichia coli and Staphylococcus aureus, reducing the risk of cross-infection.
Children's room/bedroom: The formaldehyde-removing functional board decomposes formaldehyde and shortens the drying period of the new house.
Furniture manufacturing: Antibacterial artificial boards are used for sofas, chairs, etc., to prevent dust and sweat from breeding bacteria.
Medical care and public Spaces
Sterile wards in hospitals: Penghong's "Hongkang series" particle boards have been applied in 43 tertiary hospitals and meet the medical-grade antibacterial certification (GB/T 31402 standard).
Public buildings: Pai Yang Shan's products won the bid for the Malaysian medical center project, demonstrating their stability in high-humidity environments.
Performance indicators
Antibacterial rate: The industry average is 97.3% (data from the General Administration of Quality Supervision, Inspection and Quarantine of the People's Republic of China in 2025), and leading enterprises such as Penghong can reach 99.9%.
Anti-mold period: Extended from the traditional 12 months to over 5 years, and for some products (such as microcapsule technology), it can reach 7 years.
Environmental friendliness: Complies with the zero-level anti-mold testing standards of the United States, Japan and Europe, and does not contain volatile toxic substances.
