1. Identify from the package:
The manufacturer's name, address, instructions for use and implementation standards shall be indicated on the floor packaging produced by the regular manufacturer. Since 2001, the national standard for laminate flooring has been implemented. Its name and number are the national standard GB18580-2001 of the People's Republic of China.
Well-known brands not only have the test report produced by the quality inspection authority of China; but also the complete label on the product packaging box. Registered trademark, manufacturer, business unit, model, quantity, address, telephone number, etc. Here to remind you, don't be tempted to buy three non-reinforced wood flooring to avoid being cheated.
2. Select the wear resistance number:
The wear resistance of the laminate flooring mainly depends on the content of the surface layer of aluminum oxide, and the certain wear resistance number corresponds to a certain amount of aluminum oxide. For the household floor wear resistance is usually more than 6000 rpm, and in public places usually 9000 rpm or more, you can buy as needed.
3. Select free formaldehyde emission:
The laminate flooring contains a certain amount of formaldehyde. If it exceeds the national standard (1.5mg/L), it will be harmful to the human body. It is best to use the product with the national environmental protection mark certification or the inspection-free product when purchasing.
4. Select substrate density:
The density of the laminate flooring (high density fiberboard) should be 0.82-0.96 g/cm3, and the density is too low or too high.
5. Select water resistance:
The water resistance is reflected by the water absorption thickness expansion index, which is high in value and poor in water resistance, that is, the dimensional change is easily caused in a humid environment. Don't be convinced that the waterproof floor is misleading. Only the moisture-proof floor is currently not waterproof.
6. Select machining precision:
After assembling the floor with 6-12 pieces on the flat surface, use the method of hand touch and eye view to observe whether the processing precision is smooth and smooth, whether the gutter bite is suitable, not too loose, and should not be too tight. At the same time, carefully check the height difference and gap size between the floors.
Fake and shoddy laminate flooring features:
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.
With Hunan, Hubei, Shandong, Liaoning, Jilin, and Heilongjiang as the focal points, Beijing's suburbs are still awkward. The quality is low, not environmentally friendly, and the government departments are investigating severely. Such unscrupulous merchants only consider short-term interests, no after-sales service guarantee, and the price ranges from 30-80 yuan.
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.
