Product Introduction:
Most wood processing enterprises now use dried wood, with many manufacturers assuming the wood is dry and proceeding directly to production. However, issues like cracking, warping, and paint bubbling have arisen, which are generally not expected. The root cause is usually uneven moisture content. Despite various attempts like carbonization, hardening, and wax injection, the problem is not fundamentally resolved; what issues must be addressed at their core?
We rigorously control the incoming material quality. Wood that has been dried is not considered dried material. It must be tested for compliance upon entering the workshop, and if it does not meet standards, it must undergo secondary drying.
2. Strictly control semi-finished products, as they absorb moisture from the air during production, especially in humid air, during the summer months with high humidity, the plum rain season, where wood tends to absorb a lot of moisture, and has a high water content. Additionally, during the processing, gaps in the boards are glued with adhesive containing 40% moisture, which is prone to bulging, bursting, and wave-like phenomena. Therefore, semi-finished products must be cured before sanding and painting.
3. In response to the market, our company has developed two types of secondary drying equipment. One is an intelligent far-infrared electric energy drying box, and the other is a vacuum high-frequency drying equipment.
Advantages:
A. Multi-band automatic temperature control, high-temperature alarm, humidification, dehumidification, timed on/off.
B. Fast heating, even heat distribution, low heat loss, easy assembly and disassembly, and convenient movement.
C. Dual-purpose oil (gas) and electric, uses flat-rate electricity at night with low costs; burns oil (gas) during the day for low costs as well. Environmentally friendly and practical, featuring computer numerical control for labor-saving and efficiency.
D. Air-source heat pumps are safe and environmentally friendly, absorbing heat from the air efficiently, saving up to 70% compared to traditional methods, several times more.
E. Vacuum high-frequency secondary drying equipment is especially suitable for thick, hard, large-section square timbers (which require a long time with conventional drying methods), as well as valuable woods like rosewood, huanghuali, and winged elm.
