What aspects to look for in the choice of laminate flooring?

Anticorrosive wood is the ordinary wood after artificially adding chemical preservatives, so that it has the characteristics of anti-corrosion, moisture-proof, fungal-proof, anti-insect ants, mildew and waterproof, etc., can directly contact the soil and humid environment, often used in outdoor flooring, engineering, landscape, anti-corrosive wood trellis, etc., for people to rest and enjoy the natural beauty, is an ideal material for outdoor flooring, garden landscape, wooden swings, entertainment facilities, wooden plank roads, etc., favored by horticultural designers, but with the development of science and technology, Antiseptic wood has been very environmentally friendly, so it is often used in interior decoration, flooring and furniture, and interior decoration designers also like antiseptic wood very much. There is also a kind of preservative wood without preservatives - deep carbonized wood, also known as heat-treated wood. Carbonized wood is the effective nutrient of the wood is carbonized, and the decaying bacteria survive by cutting off....

When installing laminate flooring at home, you need to carefully select the best products. How to choose laminate flooring? PChouse will take you to find out.

1. Products of well-known brand manufacturers.

Laminate flooring is a high-tech product, from the appearance of the very difficult to distinguish the quality of good or bad, unless after the quality inspection. Therefore, we recommend consumers to buy branded products. Well-known brands have generally been tested by market operations and have established a good image in the minds of consumers.

2. Identification from the packaging.

The floor packaging produced by regular manufacturers should have the manufacturer's name, address, instructions for use and implementation standards marked in Chinese. Since 2007, the national standard for laminate flooring has been implemented, and its name and number are the national standard: GB T18102-2007 impregnated paper laminated wood flooring.

3. Select the number of wear-resistant revolutions.

The wear resistance of laminate flooring mainly depends on the content of aluminum oxide on the surface, and a certain number of wear resistance revolutions corresponds to a certain amount of aluminum oxide content. For household flooring, the wear-resistant rotation rate is usually more than 6000 rpm, and in public places, it is usually more than 9000 rpm, which you can choose according to your needs.

There are four key inspection indicators for laminate flooring: formaldehyde release, surface wear resistance, water absorption thickness expansion rate and geometric dimensions of the floor.

1. Formaldehyde emission determination: choose a large-mouth bottle with good sealing performance, saw several alternative brands of the same size, put it into different bottles, seal it for 24 hours, open the bottle, smell it one by one, and you will compare which brand of floor formaldehyde release is smaller. If you are afraid of inaccuracy, you can smell it with two people and be more sure.

2. Surface wear resistance: use No. 180 sandpaper (sandpaper thickness, no big problem), the same person, with the same strength and method, to rub the same place of the floor back and forth continuously, 50 times. Without aluminium oxide flooring, it is likely that the wood grain paper will be severely damaged.

46 grams of wear-resistant paper flooring, there are basically no serious scratches on the surface; Wear-resistant paper with 38 grams or less will have varying degrees of wear and tear on the surface. 3. Expansion rate of water absorption thickness: Alternative samples of similar size are sawed, and after numbering, put them in boiling water for 5-8 minutes.

Take them out and compare how well they swell around the edges. It is best to use a micrometer in advance to measure the thickness of the measuring point of the sample and mark it. After soaking in boiling water, take it out and measure its thickness, and you can calculate the expansion rate of the relative water absorption thickness of the floor after soaking in boiling water.

4. Geometric dimensions of the floor: This comparison test requires a comparison of the whole board. a) Piece two floors together and touch the height difference of the joints with your hands; In the model room where the floor is sold, you can also consciously touch it and compare it.

The difference between brands should be obvious. b) Secondly, look at the tightness of the splicing gap. Some floors have side bends, and the joints will not be very tight.

This reflects the machining accuracy of the floor.

There are precautions to be taken when choosing laminate flooring:

One: environmental protection.

Laminate flooring contains a certain amount of formaldehyde, if it exceeds the national index (it will be harmful to the human body, it is most suitable to choose products with national environmental protection marks or products exempt from inspection when purchasing. Don't believe the saying of "zero formaldehyde" for shopping guides, the most reliable way is to ask for environmental protection certificates, inspection reports and other supporting materials.

Two: abrasion resistance.

The abrasion resistant agent pressed on the surface of laminate flooring is aluminum oxide, and the content of aluminum oxide and the thickness of the film determine the number of wear resistant revolutions. The higher the content and film degree, the higher the number of revolutions, the more wear-resistant, and the longer the life of the floor. The wear-resistant speed on the market is 6000 rpm laminate flooring, and there will be AC3 on the floor, and the larger the number of revolutions, the greater the identification value.

Three: base material.

At present, the base material of laminate flooring on the market is basically from economic fast-growing forests, and the wood is processed into MDF. The higher the density, the greater the internal bonding strength, and the better the quality of the plate. When choosing laminate flooring, the whiter the base layer, the better the quality.

Press the edge of the substrate with your fingers to see if the ash is off, if there is no powder, wood residue, etc., it means that the quality of the substrate is good.

Four: splicing tightness.

Since the back of the laminate floor does not have a keel and does not need to be spliced with glue, the tightness of the tongue and groove is very important. At the purchase site, you can take the sample of the two floors and assemble them to see whether they are neat and tight after assembly. The floors were spliced together, and it was difficult for the two of them to break them together.

Five: length and thickness.

Laminate flooring is generally divided into two types: 12mm and 8mm. The 12mm floor is closer to the solid wood floor, and the foot feel is a little better. There are two specifications on the market, large and small, the large board is 120cm long and the small board is 80cm long.

If the room is relatively large, it is recommended to choose a large slab, and the paving effect is good; If the room is relatively small, it is recommended to choose a small board to save materials.

Generally speaking, the following points should be paid attention to when choosing laminate flooring:

1. Expansion rate of water absorption thickness: the expansion rate of water absorption thickness of excellent products is below 2 5; The value of the expansion rate of the water absorption thickness of the first-class product is below 4 5. Bubble with water, absorb a lot of water and have poor quality.

2. Surface wear resistance: The floor is called a false floor because it has no wear-resistant layer or a very low wear-resistant revolution. On the surface, this type of flooring is indistinguishable from real laminate flooring, and after sanding it with sandpaper several times, you will notice that the decorative pattern is polished and immediately turns white.

This kind of floor is called fake flooring. The stronger the abrasiveness, the more expensive it is. The wear-resistant rotation rate of the public place level is more than 9000 rpm; If you have a large family and don't pay much attention to maintenance, you can choose one with higher wear resistance; However, if you pay more attention to the maintenance of the floor, the floor is less likely to be worn by strong and hardware, and it may be more economical to choose one with relatively low wear resistance.

Household wear-resistant revolutions of more than 4000 rpm are fine. You can wipe it with sandpaper, and it is easy to turn white if it is of poor quality. The abrasion strength of laminate flooring mainly depends on the coating of aluminum oxide crystals (commonly known as gemstones).

The higher the aluminium oxide crystal content per unit area of the floor, the higher its wear resistance.

3. Formaldehyde release: The formaldehyde emission value of grade A products is within 9mg 100g. Grade B 9 to 40 mg 100 grams, up to grade B can be used. The quality of the glue determines the pollution size of the laminate floor, and the formaldehyde content of the glue is low.

4. Density: The density of qualified products is 0 9g cm3.

5. Moisture content: The moisture content of qualified products is in the range of 3 0-10 0. When people buy flooring, they can check this data with a product inspection certificate.

6. Whether the tongue and groove are straight. The completeness of the tongue and groove is directly related to the life of the floor.

7.In the case that there are no problems with the above, you can consider the aesthetics of laminate flooring, for example, the design of Gabos flooring is very beautiful.

Hope it helps.

1. The number of surface wear-resistant revolutions This index is selected according to the use occasion, which is generally about 6000 rpm for household use and about 9000 rpm for public use. Second, the free formaldehyde content laminate flooring in the adhesive contains a certain amount of formaldehyde, excessive formaldehyde is harmful to the human body, if the human body is in a high concentration of formaldehyde environment for a long time, there will be a risk of carcinogenicity. China has promulgated mandatory standards for formaldehyde concentrations in public places, which are not exceeded.

For the detection method of laminate flooring, the state adopts the "perforation extraction method", which stipulates that it does not exceed 30mg 100g, and it is best to be below 9mg 100g. 3. The higher the expansion rate of water absorption thickness, the easier it is for the floor to expand. The State sets this target within 2 per cent.

Fourth, the internal bonding strength five, the surface of the cigarette burn resistance to the cigarette on the floor, to see if there are cracks, black spots, bubbling on the surface, if not, the floor flame retardant is better. 6. The higher the density, the better the mechanical properties of the product and the better the impact resistance. 7. Static bending strength and elastic modulus 8. Surface scratch resistance Needless to say, everyone understands this.

9. Surface impact resistance. 10. Peel resistance This index reflects the quality of the gluing between the surface decorative layer and the substrate of the laminate floor, if the gluing quality is poor, the decorative layer will peel off after the product is used for a period of time, which must be paid attention to before the good floor will be selected.

I haven't said much, three points, substrate, environmental protection, and wear-resistant.

For how to choose high-quality laminate flooring, Shenzhou Wood suggests starting from nine aspects: brand, material, thickness, surface wear-resistant speed, formaldehyde release, after-sales service, moisture-proof measures, and packaging.

In terms of brand, it is generally better to choose well-known brands, which can ensure product quality and after-sales service.

In terms of material, normal laminate boards should be based on high-density fiberboard.

The choice of laminate flooring thickness is generally based on international standards, and it cannot be less than 8mm, so that it can be strong enough.

For the surface wear resistance of laminate flooring, its initial wear resistance value is generally more than 6000 revolutions. For the amount of formaldehyde emitted, the standard for green building materials stipulated by the national environmental protection organization is not higher than 9mg 100g. After-sales service mainly depends on whether there is property insurance, whether there is a warranty card, whether it is sold directly by the manufacturer, whether the product is monopolized, etc.

Flooring, moisture-proof is one of the important criteria, laminate flooring is mainly to see whether it has a special moisture-proof mat, whether there is a thick moisture-proof layer on the floor, whether the glue is a special floor waterproof glue, etc. If you buy imported laminate flooring, see if it has a Chinese logo and customs inspection certificate.
