Laminate flooring quality indicators

Laminate flooring, wood flooring Laminate scientific name, is a high-density fiberboard, surface mount and wear decorative impregnated paper impregnated paper, stickers on the back of the balance sheet, made by hot pressing, open mortise and other processes of enterprises mouth floor. And this production process to be used in a large number of adhesive. Wood flooring, laminate flooring is currently responsible for all laying by the supplier.Ways to cover up an old patio in Thailand

Laminate flooring structure by four structures: the first layer: wear layer. Mainly by Al2O3 (aluminum oxide), with strong wear resistance and hardness, some laminate flooring can not meet the requirements of standard melamine composition. Second layer: decorative layer. Is a layer of melamine resin impregnated by paper printing paper imitation precious species of wood or other patterns. Third layer: the grassroots level. Medium density or high density laminate. High temperature, high pressure processing, have some proof, flame retardant, the basic material is wood fiber. Fourth layer: balancing layer. It is a layer of kraft paper, there is a certain strength and thickness, and impregnated with resin, played the role of moisture-proof floor deformation.

The main quality indicators surface wear rotation, with ≥9000 turn public places, home ≥6000 rpm. Above refers to the number of revolutions of the initial ground value, that is open at the end surface of the decorative layer occurs, rather than the final value that is wearable all worn floor. Some markets are highly reinforced laminate flooring wear rotation express, but is likely to be the subject of wear and the final value. Thickness swelling thickness swelling refers laminate flooring soaked in water for a period of 25 ℃ grassroots level increased absorption thickness is represented by%. The larger the expansion, the strength of the floor damp fall after the larger and there will even fall off the surface projections, seriously affecting life. Various brands currently marketed its thickness swelling can be a difference of more than ten times the size.

Surface impact resistance that is a prescribed method of floor impact test, after leaving the pit diameter impact is the impact on the basis of good or bad performance, the smaller the diameter, the better impact resistance, and long service life. Wear-resistant laminate flooring in 0.1 mm thick or more, up to 0.7 mm thick.Outdoor benches garden benches replacement slats

 

Formaldehyde emission requirements according to GB18580-2001 belong laminate flooring can be directly used for indoor products, so it must meet E1 formaldehyde emission level, namely ≤0.12mg / L. In addition there are static bending strength, internal bond strength, density, moisture content, bonding strength and other indicators. Sales should express its abrasion resistance levels and limited level of formaldehyde. Decking material reviews 2015
