How to choose home laminate flooring?
Environmental protection index refers to the composite floor formaldehyde emissions. Formaldehyde is an indispensable ingredient in the process of flooring production, and it is also the most important pollutant.. At present, the domestic standard of composite floor formaldehyde release is 20 mg per 100 grams, the international standard is 100 grams, release 8 mg. The less formaldehyde content, the less pollution; because the composite flooring production process contains a large number of high-strength PVC aggregate and high strength adhesive, so its compressive tensile strength can generally meet the use requirements. The water resistance index of composite floor is checked by water thickness expansion rate. The lower the water thickness expansion rate is, the better the moisture resistance and water resistance are.
High quality imported in general have international environmental protection Blue Angel logo design, domestic environmental standards certification authority is the CCEL - China Committee green product certification mark, the domestic environmental protection logo for the seven ring pattern.
Buy composite flooring, first look at the surface: the surface of the material is mainly melamine or three oxidation of two aluminum, to three oxidation of two aluminum, better wear resistance. The surface thickness is thin only 1 millimeters, the thickness may reach above 5 millimeters. Of course, the same material, thicker, more wear-resistant. Wear to "turn" as the index, abrasion resistance of 4500 rpm, available to the bedroom, using a five year period; 1000 rpm can be used in the family living room, dining room, use period of ten years; 1500 is suitable for public places. Second, look at the bottom: the main role of the bottom layer is to resist the deformation of the composite floor in dry, wet, cold, and thermal changes. If the use of geothermal heating, it is best to use composite floors
Laminate flooring use density board or high density board after molding, coating, cutting, cutting and other production processes and interfaces, need material floor film, artificial board, polyurethane paint to formaldehyde agent, etc.. The composite floor is a new kind of ground paving material, because it is very lifelike imitation wood texture, abrasion, impact resistance, fire hot, damp proof, mothproof, no color, no deformation, easy cleaning, convenient construction and other advantages beyond the wooden floor, the deficiency is a feeling hard, lack of flexibility, the damage can not be repaired.
