Qizhen Cheap Laminate Flooring
Laminate flooring, scientific name impregnated paper laminated wooden flooring, high density fiberboard substrate surface mounts decorative impregnated paper and wear-impregnated paper, affixed to the back of the balance of paper processes made by hot pressing, open the tongue and groove enterprisesmouth floor.
First layer: wear layer. Composed mainly by Al2O3 (aluminum oxide), has a strong abrasion resistance and hardness, melamine laminate flooring cannot meet the standards.
Second layer: decorative layer. Is a layer of melamine resin impregnated paper, paper printing imitation precious species of wood grain or other patterns.
The third layer: the grass-roots level. Medium density or high density laminates. High temperature, high pressure processing, the moisture-proof, flame retardant properties, the basic material are wood fiber.
Fourth layer: balancing layer. It is a layer of kraft paper, there is a certain amount of strength and thickness, and impregnated with resin, and play a role in dampness, floor deformation.
Main quality indicators
Surface wear revolution
Public places turn, families with 9000 6000 rpm. More than the number of revolutions is the value of the initial grinding, namely the surface ornaments layer exposed at the end, rather than wearable final value that the floor is all worn out.Market is some strengthening the laminate flooring express high wear revolution, but it is likely that the final value of the subject wearable.
Thickness swelling laminate floor soaked in 25 C waters for some time after the primary absorption thickness increase the degree to%. The expansion rate of the greater, the greater decline in strength after the damp floor, and surface projections appears even fall off, seriously affect the service life. Currently commercially available various brands of its thickness swelling the size difference of more than tenfold.
Surface impact resistance
The basis for the impact test, i.e. a predetermined method on the floor of the pit diameter is left after impact shock performance quality, the smaller the diameter, the better the impact resistance, long service life. Laminate flooring, wear-resistant layer thickness 0.1mm up to 0.7mm thick.
GB18580-2001 requirements can be directly used for indoor products. Laminate flooring is formaldehyde emission E1 class 0.12mg / L.In addition, static bending strength, internal bond strength, density, moisture content, bonding strength indicators. Sales should be to express its wear-resistant grades and formaldehyde limited level.
Advantages and disadvantages
Wear: Approximately Pu Tongqi the decorated floor more than 10 to 30 times.
Beautiful: The available computer simulation of a variety of wood grain patterns, colors.
Stability: completely broken up the organization of the original timber, destroyed anisotropic and bulking shrinkage, characteristics, size is extremely stable, especially suitable for the system to warm the room.
In addition, impact resistance, anti-static, anti-pollution, light resistance, resistance to cigarette ignition, easy installation, simple maintenance, etc.
The blisters and irreparable damage to the foot feeling poor.
Laminate flooring, as well as wood flooring, all by the supplier is responsible for laying.
Of particular note is the past. Dealers said laminate flooring is waterproof floor, this is only for use of composite floor surface in terms of the effect of hardening To avoid blisters.
Wearable level and formaldehyde limited level of sales should expressly laminate flooring.
