The floor substrate is generally made of high-density fiberboard (only those fake and shoddy products mostly use unqualified medium density fiberboard or other fiberboard with worse quality or performance, because the cost of this kind of fiberboard is low). The raw material of fiberboard is wood fiber, such as purchased wood chips, fruit trees and other wood, which is ground into fiber and fiber powder by specific process, Then add adhesive and press the high-density fiberboard with a density of more than 850kg / m3 under the conditions of high temperature and high pressure.
The quality of high-density fiberboard for making high-quality laminate floor is affected by many factors, such as tree species and tree species matching, production process, adhesive type, sizing process, whether to apply waterproof agent, etc. The quality of laminate produced by high-density fiberboard with different quality is different. The laminate made of high-quality high-density fiberboard has high strength, impact resistance, good moisture-proof performance, good stability, not easy to warp and deform, and low formaldehyde emission. The laminate floor made of low-quality high-density fiberboard will not meet the standard requirements and use requirements.
