Counterfeit and inferior laminate flooring usually uses domestically produced cheap decorative paper. This decorative paper pattern is fuzzy, and the biggest drawback is that it is generally not resistant to ultraviolet rays and will fade after sunlight exposure. This is why some consumers reflect the discoloration of the balcony and windows after three or four months of floor installation.
Laminate flooring, originated in Europe, is a new type of flooring based on wood-based panels. It can be divided into two types: laminate flooring with medium and high density fiberboard and laminate flooring with woodgrass. class. It is widely used in the floor laying of conference rooms, dance halls, hotels and other places in family rooms and public places.
Focusing on the current flooring market, counterfeit laminate flooring presents the following five characteristics:
1. Generally, wear-resistant paper with a content of about 20 g/m 2 of aluminum oxide or no wear-resistant paper is used. Low-density boards, (very few use medium-density boards), the wear resistance is usually between 100-3000 rpm. The corners will be worn out for up to one or two years.
2. Usually used domestic cheap decorative paper, this decorative paper pattern is blurred, the biggest drawback is that it is generally not resistant to ultraviolet rays, and will fade after sunlight exposure. This is why some consumers reflect the discoloration of the balcony and windows after three or four months of floor installation.
3. The substrate is poor. With medium or low density board or particle board, the quality index is unstable and the formaldehyde is seriously exceeded.
4. The processing accuracy is poor, and often claimed to be: imported large board, domestic slotting.
5. The packaging is rough, the printing quality of the brochure is poor, the content is patchwork, and the slogan sells a set of sets, often stealing the contents of the album of the big company.
The best way to buy quality laminate flooring is:
1. Buy laminate flooring, look at the surface first: the surface material is mainly melamine or aluminum oxide, and the wear resistance of aluminum oxide is superior. The surface layer is only 1 mm thin and can be as thick as 5 mm or more. You can't just look at the promotional materials of the business, you need to understand the actual situation of the product. The promotional materials of many merchants indicate that their own wear rotations are '15,000 rpm', '18,000 rpm', etc. The products that are normally sold, except for a few, generally do not reach this number of revolutions.
Of course, the same material is thicker and more wear resistant. The wear resistance is measured by 'turning', the wear resistance number is 4500 rpm, and the bedroom can be used for five years; the 1000 rpm can be used for the family living room and dining room, and the use period is about ten years; 1500 rpm is applicable to public places. . Secondly, look at the bottom layer: the main function of the bottom layer is to resist the deformation of the composite floor in the dry, wet, cold and hot changes. If geothermal heating is used, it is best to use a composite floor.
2. Do not purchase 'three no' products, the products of 'all foreign packaging' should be carefully purchased, and the formal products should have Chinese signs and related instructions in accordance with domestic laws. High-quality imported laminate flooring generally has the international environmental protection mark blue sky to make the pattern, the domestic environmental protection standard authority certification body is CCEL-China environmental protection mark product certification committee, the domestic environmental protection mark is the seven-ring pattern. You should buy some products from more famous companies. Most of these enterprises have large production scale, advanced production equipment, certain testing methods, guaranteed product quality, good after-sales service, and problems in product quality. You can't just buy a cheaper product, but buy a product with a very low price. The raw material cost, production cost, sales cost and normal profit of the qualified products shall be around 60 yuan/square meter. Unless the promotion is carried out, the normal price should not be lower than this price. And some cheap products are likely to use unqualified raw materials.
3. The environmental protection index refers to the amount of formaldehyde released from the laminate flooring. Formaldehyde is an indispensable material for bonding in the production of laminate flooring, and it is also the most important pollutant. The current domestic standard for formaldehyde release from laminate flooring is 20 mg per 100 grams, and the international standard is 8 grams for release of 8 mg. The less the formaldehyde content, the smaller the pollution; because the laminate flooring production process contains a lot of high-strength PVC aggregate and high-strength adhesive, its compressive tensile strength can generally meet the requirements of use.
4. The water resistance index of the laminate flooring is evaluated by the water thickness expansion rate. The lower the value of the water thickness expansion ratio, the better the moisture resistance and water resistance. Because of the Chinese national standard for the release of formaldehyde from laminate flooring, no more than 1.5MG/L is in line with national standards. The wear-resistant number of wear-resistant rotating wood laminate flooring should be 6,000 rpm, and the public space should be 10,000 rpm. Otherwise, it may be damaged to varying degrees after 1-3 years of use. It is the ultimate goal to choose your favorite color within the price range that can be picked up. Pay attention to the flaws on the pattern when inspecting the goods.
