Better than three layers of solid wood.
In fact, the substrate of multi-layer solid wood flooring is our common three-plywood and five-plywood. Except for some imported or big brands, many small multi-layer solid wood flooring manufacturers will not produce their own substrates at all. They just need to buy ready-made plywood and sell it directly on the market. Naturally there is no perfect quality assurance.
Obviously, the substrate of three-layer solid wood needs more technological treatment, because its core board is composed of countless adjacent small strips, and there are still appropriate gaps between each strip, so that the wood can fully expand and contract without affecting the overall deformation. There is no finished product of this kind of wood seed board on the market, so the three-layer manufacturer can only produce it by itself, and it can't be completed without mature technology.
Better than three layers of solid wood on the panel.
The floor panel plays a very important role in multi-layer and three-layer solid wood. Generally, high-quality materials with high wear resistance are used to protect wear resistance. The panel requirement of multi-layer solid wood floor is 1.6- 1.8MM thick, while many floors in China are only 0.6MM thick, and the wood in this 0.6MM accounts for only 0.3MM at most, and 0.3MM is paint. Imagine a paper-like surface layer, which is naturally easy to expose the underlying substances after long-term use and is not easy to repair.
The three-layer solid wood surface board generally reaches 3MM, 4MM or even 6MM, and can be polished and refurbished again after several years of use without exposing the core board. All the indexes of the three-layer solid wood flooring from abroad are formulated according to international standards, but in foreign countries, only the surface plate with a thickness of more than 2MM can be called the floor decoration material, and only the "thin paper" with a thickness of 0.3MM after rotary cutting can only be seen but not used.
Three-layer solid wood superior to environmental protection
No matter what kind of floor, the connection between two adjacent floors must be through adhesive. So the fewer layers there are, the less places need to be pasted. In terms of the amount of glue used, three-layer solid wood is naturally more dominant. Moreover, domestic three-layer solid wood is basically profitable by export. For example, 90% of the three-layer solid wood flooring in Jinqiao is exported, while the requirements for environmental protection abroad are obviously stricter than those in China, which once again ensures the environmental protection performance of the three-layer solid wood.
Better than stable multi-layer solid wood
Wood has internal stress, which is the force that causes wood to crack and distort. Multi-layer solid wood generally adopts rotary cutting technology because it requires relatively thin wood. After rotary cutting, the structure of the wood itself will be destroyed, so this internal stress will also be destroyed, making the wood "dead" and naturally there is no possibility of deformation.
Better than the price of multilayer solid wood.
Due to many factors such as production technology and material utilization, the price of multi-layer solid wood is obviously lower than that of three-layer solid wood.
By comparing the base, panel, environmental protection, stability and price, we will find that the three-layer solid wood floor and the multi-layer solid wood floor are evenly matched, and both have their own advantages. But relatively speaking, the three-layer solid wood floor is better. The quality, design, workmanship and environmental protection of floors are much better than those of multi-layer solid wood floors. The price and stability of multi-layer solid wood flooring are more dominant.
