Ninety-Nine Percent Of People Still Don't Know The Techniques For Choosing Building Material

Board Selection Tips**
1. **Choose Type Based on Usage**
- **Cabinet/Furniture**:
  - Particleboard (high cost-effectiveness, good stability, but choose a brand with moisture-proof model).
  - Eco-board (core material is solid wood strips, good environmental performance, suitable for on-site processing).
  - Flooring/Countertops:
    - Multi-layer solid wood board (moisture-proof, resistant to deformation, suitable for underfloor heating environment).
    - Osb Board (high strength, suitable for load-bearing structure).
    - Decorative surface:
      - Fireproof board (high temperature resistance), Pet Board (anti-fingerprint, high appearance quality).
2. **Check Environmental Grades**
- **Domestic Standards**: Preferentially select ENF grade (≤0.025mg/m³) or E0 grade (≤0.05mg/m³).
- **International Certifications**: F4 star, CARB certification (more strict in the US).
- **Verification Method**: Require the merchant to provide CMA test report, focusing on checking the data of formaldehyde and TVOC.
3. **Observe Physical Properties**
- **Flatness**: No unevenness or cracking on the surface of the board, no hollows on the side.
- **Density Test**: Press the edge of the board with your hand, high-density board has no obvious indentation.
- **Moisture Resistance Test**: Take a small piece of the board and soak it in water for 24 hours, observe the expansion rate (expansion rate < 8% is ideal).
4. **Pay Attention to Brand and After-sales**
- **Recommended Brands**: Tuobao, Qiannanzhou, Lushuihe (domestic with good cost-effectiveness), Knosban (imported).
- **Avoiding Scams Tip**: Be cautious of low-price "junk board", prioritize choosing authorized stores or official channels for purchase.
5. **Detail Inspection**
- **Edge Sealing Process**: Laser sealing > PUR sealing > EVA sealing, sealing is tight without glue lines.
- **Surface Quality**: Use a key to lightly scratch the surface, no obvious scratches; the pattern is clear without a grainy feeling.
- **Core Material Quality**:
  - Eco-board: Spruce core > Poplar core, the wood strips are closely arranged without gaps.
  - Particle board: Large particles > Shreds, the glue is uniform without a pungent smell.
