How to prevent BAMBOO Storage Cabinet from getting infested with insects or mold?

In the raw material pretreatment stage, bamboo needs to undergo a strict high-temperature hydrothermal carbonization process. This process lasts for 8-12 hours at a high temperature of 135-150℃ and a pressure of 0.6-0.8MPa, and completely decomposes the hemicellulose and lignin in the bamboo through steam pyrolysis. This process not only eliminates biologically active substances such as insect eggs and mold spores, but also converts the sugar inside the bamboo into a stable carbonized structure, fundamentally cutting off the nutrient source for the growth of insects and mold. The moisture content of the bamboo treated in this way is stabilized at 7%-9%, and the density is increased to 1.25g/cm³, forming a dense texture similar to sandalwood, and the moisture absorption rate is reduced to below 3%, which is significantly lower than the critical humidity for mold growth.
In terms of structural process optimization, the BAMBOO Storage Cabinet adopts a five-layer criss-cross lamination technology, and the carbonized bamboo pieces are arranged vertically and cross-wise at 0°/90°, and a composite board is formed by high-frequency hot pressing. This structure enables the fiber layer to form a "three-dimensional grid barrier" to destroy the linear decay path of the borer. Experimental data show that the board treated by this process has the highest level of anti-insect performance of ASTM D3345 standard, and the bending strength is increased to 125MPa, which effectively prevents water accumulation in gaps caused by structural deformation. All joints are sealed with food-grade silicone, and the millimeter-level precision of laser cutting is used to achieve a joint gap of less than 0.1mm, eliminating moisture penetration.
The surface protection system includes three protective layers: the bottom layer is a permeable nano bamboo vinegar coating, which contains acetic acid and phenolic compounds that can penetrate 3-5mm into the bamboo material to form a broad-spectrum antibacterial environment; the middle layer uses water-based polyurethane modified paint, which forms a continuous film layer through cross-linking reaction, and the water resistance reaches GB/T 1733-93 standard 240 hours without blistering; the surface is coated with natural wood wax oil, which closes the micropores of bamboo material through capillary action, and the surface contact angle can reach 110°, achieving a hydrophobic and anti-fouling effect.
Daily maintenance scientific guidance recommends that users control the ambient humidity in the range of 40%-60%, and humidity-responsive bamboo charcoal bags can be placed in the cabinet. When cleaning, use a weakly acidic plant cleaner with a pH of 6.5-7.5 to avoid damaging the surface protective layer. If the cabinet is in a high-humidity environment for a long time (such as coastal areas), it is recommended to use an infrared drying device (below 40°C) to gently dehumidify the cabinet for 2 hours every 6 months. If local mildew is found, first use a soft brush to remove the surface mycelium, then use 75% medical alcohol and a microfiber cloth to wipe it in one direction, and finally apply a special bamboo repair paste (containing nano titanium dioxide photocatalyst ingredients) for photocatalytic sterilization.
