Termite Resistant Board

The termite resistant properties of magnesium oxide (MgO) boards stem from the synergistic effects of material attributes, structural design, and process treatment, effectively resisting insect erosion. The following details the technical principles, performance verification, and application scenarios:

1. Core Technical Principles of Insect Repellency

Natural Insect-Resistant Substrate of Inorganic Materials:
Magnesium oxide boards are primarily composed of inorganic materials like magnesium oxide (MgO) and magnesium chloride (MgCl₂)/magnesium sulfate(MgSo4). The hardened magnesia cementitious system contains no organic nutrients (such as cellulose or starch) necessary for insect survival, fundamentally cutting off the pest food chain. In contrast to wooden boards (which contain wood fibers and are prone to termite and borer damage), MgO boards lack "attraction" for insects.

Dense Structure Blocking Insect Pathways:
Through roll-pressing technology, the board achieves a density of 0.9–1.25 g/cm³ with low internal porosity and tight intermolecular bonding. Insects (e.g., termites, cockroaches) cannot gnaw through to form channels or nest inside, whereas ordinary gypsum boards (high porosity) or wooden boards are easily  eaten (hollowed out by pests).

Alkaline Environment Inhibiting Insect Activity:
The board has a pH of approximately 9–11 after curing, creating a strongly alkaline environment that damages the mucus layer and enzyme activity on insect bodies, suppressing their habitation and reproduction. Most insects thrive in neutral environments (pH 6–8), making the high alkalinity repulsive.

2. Quantitative Data and Testing of Insect Resistance

Verification by Pest Resistance Testing Standards:
According to GB/T 24128 Test Method for Insect Resistance of Building Materials and Products, magnesium oxide boards showed no termite erosion traces after 12 weeks of termite contact testing, achieving the highest insect resistance grade (Grade 0, no insect damage). Wooden boards, in the same test, had a termite erosion rate exceeding 80%.

Insect Resistance Comparison Data:

Material Type	Termite Damage after 12 Weeks of Contact	Insect Habitation Risk	Long-Term Insect Resistance
Magnesium Oxide Board	No boreholes or powder on the surface	Extremely low	Long-term (over 10 years)
Ordinary Wooden Board	Dense boreholes, structural damage	High	1–2 years
Ordinary Gypsum Board	Edges gnawed, internal structure loosened	Medium	3–5 years

3. Typical Application Scenarios of Insect Repellency

Warehousing and Logistics:Magnesium oxide boards can be used for walls and ceilings in grain warehouses and logistics warehouses. Meanwhile, attention should be paid to preventing insects (such as rice moths and drugstore beetles) from invading stored materials through gaps in the boards, so as to reduce losses caused by pests.

Humid and Insect-Prone Areas:
In basements, greenhouses, and other humid environments, MgO boards are both mildew and insect resistant, preventing moisture bugs and cockroaches from hiding in the boards. Compared to wooden partitions, greenhouses using MgO boards have a 70% lower pest incidence.

Ancient Building Restoration and Protection:
In the renovation of ancient buildings, MgO boards can replace insect-prone wooden components for partitions, ceilings, etc., maintaining traditional architectural styles while providing long-term insect resistance and reducing maintenance costs.

Military and Special Projects:
Buildings in military field camps and border defense posts using MgO boards can resist erosion from termites, ants, and other insects in tropical regions, ensuring the structural safety of temporary or permanent constructions.

4. Extended Advantages of Insect Repellency

Synergistic Effect with Fire and Mildew Resistance:
Magnesium oxide boards combine A1-grade fire resistance, powerful mildew resistance, and insect repellency. In tropical or humid jungle environments (e.g., Southeast Asian infrastructure projects), they address fire, mold, and pest risks in one solution, reducing material replacement frequency.

Environmental Friendliness and Low Maintenance Costs:
Unlike traditional wooden boards that require pesticide spraying, MgO boards need no chemical insecticides, avoiding harmful substance release and complying with green building standards. Their long-term insect resistance also reduces the cost of regular pest control, especially for remote or hard-to-maintain projects.

Packaging and Shipping of Termite Resistant Board

 

FAQ:

Q: How should I store the panels?
A: Store the boards flat on a well-supported, elevated surface in a cool, dry environment, keeping them in the manufacturer's original packaging until use. If storing outdoors or on-site, cover them with waterproof material to protect against weather, direct sunlight, surface contamination, and construction traffic.

Q: How do I cut the panels?
A: MgO boards are optimally cut with carbide-tipped tools, which ensure clean, square edges for higher-quality installations. Circular saws-including table saws-are the preferred tools. For thin sheets, score the fiberglass mesh from the smooth side using a disposable knife, then snap the sheet along the scored line.
