Product Introduction
Mold Resistance of Glass-Magnesium (MGO) Board as Wall Paneling
The exceptional mold resistance of G-Mg board stems from a synergistic triple-defense mechanism, comprisin
1,Core Mold-Resistance Mechanisms
- Inorganic Alkaline Environment Disrupts Survival Conditions
MGO boards maintain a stable pH of 9–10 (vs. mold-favorable pH 4.5–6.5), creating a highly alkaline environment that disrupts fungal metabolism and inhibits reproduction.
- Mold Prevention through Low Organic Nutrient Sources
Our magnesium oxide boards utilize a special formula that either contains no organic fibers or strictly controls the content and processing of organic components (such as wood fibers). This minimizes the availability of nutrient substrates that mold relies on, reducing the mold growth rate by 92% compared to traditional boards with high organic content.
- Moisture Barrier Structure to Block Water Infiltration
Crystal Hydration Lock Mechanism
The board's internal structure forms 5.1.8 or 5.1.7 phase crystal networks through the reaction of magnesium oxide with magnesium chloride or sulfate. These crystals create a dense, water-locking matrix via hydration complexation, effectively inhibiting moisture penetration.
- Closed-Cell Hydrophobic Design
The addition of fillers like perlite creates a closed-cell micro-structure, which, combined with a glassy glazed surface layer, forms a hydrophobic interface. This dual physical barrier achieves highly efficient water resistance.
The combination of chemical water locking through crystal hydration and physical closed-cell structures results in significantly improved moisture resistance compared to conventional boards.
2,Empirical Performance Validation
Zero mold growth observed at 95% RH (e.g., southern China monsoon conditions).
No deformation, softening, or mold after water immersion and air-drying; structural integrity maintained.
Exceeds mold/antimicrobial standards (e.g., JIS Z2911 Grade 1) with 99% antibacterial rate.

4, Engineering-Grade Enhancements
Our premium Magnesium Oxide Boards (MgO Boards) feature anti-efflorescence treatment with special modifiers, keeping free chloride ion content at ≤3%. This advanced process not only prevents surface salt crystallization but also significantly enhances moisture resistance, ensuring reliable mold resistance even in extreme environments.
Conclusion: Through its coordinated alkaline biocidal action, physical moisture barriers, and nutrient-free matrix, MGO board establishes a triple-defense system – delivering sustainable mold resistance and environmental safety for high-humidity applications.
