Q： How can consumers distinguish the quality of fire-resistant boards with significant price differences on the market? What material selection suggestions does Weimeijia have
A： As a fire-resistant and durable surface decorative material, the performance of HPL is closely related to the substrate, resin ratio, and pressing process. Weimeijia has been deeply involved in the field of decorative materials for more than 20 years, and summarizes the following key points for purchasing:
1、 Core performance indicators must meet the standards
Fire rating certification
The national standard GB 8624-2012 classifies fire-resistant boards into A2 (non combustible) and B1 (flame retardant) grades. Weimeijia products have passed A-level certification (test reports can be found), and there is no spread or dripping under open flames
Be wary of low-priced products falsely labeled as "fireproof boards", and request inspection reports and verify CMA/CNAS seals
Key parameters of physical performance
Wear resistant speed: High quality boards can reach over 1000 revolutions per minute High temperature resistance: no foaming or cracking after baking at 180 ℃ for 30 minutes (laboratory test data)
Acid and alkali resistance: Soak in a 5% concentration acid and alkali solution for 24 hours without corrosion (suitable for laboratory countertops)
2、 Avoiding material and process traps
Substrate determines stability
Poor quality boards are made from recycled pulp substrates, which are prone to moisture and deformation. Weimeijia uses long fiber wood pulp kraft paper (6-8 layers stacked) with a density of ≥ 1.5g/cm ³ and a 40% increase in flexural strength
Resin ratio affects lifespan
Phenolic resin content ≥ 45% is required to ensure weather resistance. Weimeijia uses imported resin (accounting for 50% -55%), which is cured under high temperature and high pressure (140 ℃/1200 tons) to eliminate the risk of delamination
Differences in Decorative Techniques
Low price board printing patterns are blurry and prone to fading. Weimeijia adopts synchronous flower relief technology, which has strong three-dimensional texture and UV resistance
3、 Suggestions for scenario based selection
Kitchen countertop: choose a thickness of 2.5mm or more+antibacterial coating (Weimeijia antibacterial series has a mold proof rate of 99.9%)
Laboratory workstation: requires chemical corrosion resistance and electrostatic conductivity (Weimeijia RM series surface resistance ≤ 10 ^ 6 Ω)
Commercial space wall: Recommended matte surface+scratch resistant process (Weimeijia XM series Mohs hardness ≥ 5)
Service advantages of Weimeijia:
Free sample testing (on-site flame testing, scratch demonstration), customized size cutting (error ≤ 0.5mm), and engineering case design support are provided
