3. Core Structural Advantages

(1) Safe & User-Friendly Design
- Anti-Pinch & Anti-Impact: Limit gears on the horizontal frame prevent the sliding board from hitting vertical frames or pinching hands during use.
- No Sharp Risks: ABS engineering plastic corner wraps (one-time molding) eliminate sharp edges and burrs, avoiding scratches on teachers and students.
- Secure Management: A universal-key lock secures the sliding board, protecting the internal all-in-one machine from unauthorized access.
(2) Durable & Low-Maintenance
- Wear-Resistant Border: The aluminum alloy border resists corrosion (CASS 72H ≥Level 10) and wear (sand drop test ≥4000g), ensuring long-term use without rust or deformation.
- Long-Lasting Pulley: High-precision bearings enable smooth sliding and a service life of over 100,000 times, reducing replacement frequency.
- Dust-Proof Sliding System: The hidden track design blocks dust and debris, avoiding sliding jams caused by dust accumulation.
(3) Environmental & Visual Comfort
- Low Formaldehyde: Eco-friendly adhesive ensures formaldehyde emission ≤0.2mg/L, meeting national safety standards for indoor teaching environments.
- Glare-Free Board: The matte metal paint surface (glossiness ≤12 gloss units) eliminates glare, reducing eye strain for students during long classes.

4. FAQ (Frequently Asked Questions)

Q: Can the board surface be used with water-based pens?

A: Only the green board surface supports water-based pens. For other colors, use soft dust-free chalk. When using water-based pens, match them with a dedicated eraser to avoid residual marks.

Q: What if the sliding board’s lock key is lost?

A: The lock uses universal keys. Contact the manufacturer to request a replacement—no need to change the entire lock.

Q: Can large teaching tools be stored in the multi-purpose slot?

A: No. The slot (width ≥30mm) is only for small items like pens or pointers. Large tools may jam the sliding system; store them separately.
