How to identify inferior AC3 laminate flooring
2. Low-tech small workshop AC3 laminate flooring. Because AC3 laminate flooring is so high-tech, some well-known brand factories can produce tens of thonds of square meters a day. Some off-brand small-scale processing plant production scale and technology standards, simply can not meet the relevant standards set by the state. The standard AC3 laminate flooring manufacturer chooses diamond cutting tools with micron precision and regularly replaces them. But the workshop board uses is an ordinary woodworking tool, the cutting precision can not achieve the request, causing the plank to have a gap, and the installment to bite is not good.
3. AC3 laminate flooring with low substrate density. In order to reduce the cost, the lower density medium density board, particleboard, and so on are used as the material for producing AC3 laminate flooring. AC3 laminate flooring should be based on a special high-density board, and its water absorption and expansion rate should be strictly controlled.
4. AC3 laminate flooring with severely elevated formaldehyde levels. The base material of high-quality AC3 laminate flooring should be melamine, while the base material of inferior flooring, uraldehyde adhesive, is only 1/7 of the price of melamine. Poor quality floor because of the production of low technology, poor base material, the formaldehyde and other harmful gases emitted by the content of serious beyond the national limit standards.
