Parquet should distinguish the quality of the board, how do you think it should be distinguished?

1. Look: The surface of high-quality composite flooring is smooth, the color is gorgeous and natural, and the back moisture-proof balance layer is thick; The surface of the inferior laminate floor is rough, the color is dull and dull, and the back moisture-proof balance layer is thin.

2. Listen: High-quality composite flooring is generally composed of a wear-resistant layer, a decorative layer, an ultra-high-density substrate layer and a moisture-proof balance bottom layer, etc., and is treated with high-tech spraying, the wear-resistant layer is thick, and it emits a metallic sound when it is scratched with hard objects such as keys, which is brittle and bright, and there are no obvious scratches. The decorative layer is made of imported materials, with clear patterns and bright colors; Some of the inferior laminate flooring is treated with ordinary resin paint, and some are treated with aluminum oxide, but the coating is thin, only one-third of that of high-quality laminate flooring, and it makes a dumb sound when it is scratched with hard objects such as keys, and there are obvious scratches.

The decorative layer is made of domestic materials, the pattern is blurred, and the color is dull.

3. Touch: The high-quality composite floor is made of high-density board, the weight of the veneer is heavy, the size is consistent, the slotting is fine, the two floors are spliced without gaps, and the joints are very smooth by hand; The inferior composite floor is made of dense fiber, the veneer is light in weight, the size is inconsistent, and there are obvious gaps in the two ground analysis splicing, and there is an obvious concave and convex feeling when touching the joint by hand.

4. Smell: Due to the different materials and equipment and processes, the high-quality composite floor is pollution-free, and the formaldehyde content can meet or exceed the national standard, and the formaldehyde content of some floors has reached the European E1 standard and passed the China green environmental protection certification, realizing the double certification of international and domestic environmental protection standards.

5. Q: The scale of enterprises producing high-quality composite flooring is large, and after-sales service and other aspects should be asked clearly.

Wooden floors are installed in bedrooms and other spaces, and the contact time with people is relatively long, so it must not have a pungent smell. Smell the smell, this trick is mainly for wood flooring, especially solid wood plywood. Parquet has more or less formaldehyde content, so you can use your nose to judge the quality of the floor.

Don't look at the number of layers more than three, in fact, the thickness of each layer is only millimeters. It will be almost cheaper in impact resistance, abrasion resistance and pressure resistance. However, there is also the fact that it is more stable with underfloor heating, so if you have underfloor heating in your home, choose a multi-layer one.

<> paint, a good paint can better protect the log layer (solid wood surface), so that the log layer can perfectly display its texture, its hardness can also protect the log layer from damage to a certain extent, and it contains relatively less formaldehyde and benzene, which is more environmentally friendly. Generally, the dealer of wood flooring should have a moisture content tester, if not, it means that the moisture content is not paid attention to this technical index. When purchasing, the moisture content of the selected wood floor in the exhibition hall is measured first, and then the moisture content of the wood floor of the same material and specification is not opened, and if the difference is +2%, it can be considered qualified.

Before buying wood flooring, you can observe whether the appearance of the wood floor is normal, and observe whether there are bubbles or paint leakage on the surface of the wood floor. If you find that the color of the wooden floor is relatively dark and the paint is thick, it is likely that the wooden floor inside is flawed and needs to be covered with paint. The multi-layer solid wood floor is made of criss-crossed multi-layer boards as the base material, selecting high-quality precious wood as the panel, and then coating resin glue in the hot press machine through high temperature and high pressure.

The moisture content of wood flooring is the most important factor affecting the deformation of the floor. The standard moisture content of wood flooring is 8%-13%, 12% in the northern region and 14% in the southern region. Wood flooring dealers generally have moisture content testers in their stores, and you can first test the moisture content of the wood floors selected in the showroom when purchasing.

Distinguish the quality of the composite board, cut it to see the cross-section, buckle or scratch it with a fingernail, and the hard point is not easy to buckle off or the scratch is very shallow or no. For solid wood, it is also to look at the cross-section, the grain is on a piece of material, even if it is good, it is not a veneer solid wood floor, some people call it ecological wood floor.

You can look at the cutting surface of the board, if the density is relatively high, the quality of the floor is better, if its material looks loose, the quality is not good.

You can ask the merchant for the floor head of the selected floor, scrape and scratch the surface of the floor several times with a metal key or nail, and then rub the scratch repeatedly with the palm of your hand. If you can't see scratches at all, it means that it is more scratch-resistant; If you can see obvious scratches or see the bottom plate, it means that the wear resistance of the floor is not up to standard, and the quality is not good.

If you want to buy parquet, at this time, you must learn to judge the quality of parquet, and you must buy guaranteed products. You can tell by tapping the board, and we can also test the waterproofness of parquet.

Now many people prefer this kind of solid wood flooring, because everyone thinks that this style is more retro, so we must choose some products with quality assurance, because we need to use it for a long time, so we must buy some quality products, of course, you can also go to the Internet to see some information first. In this way, we know how to judge the quality of the board, you can judge by tapping the board, we can listen to the sound of the board, if the sound of the board is more crisp, at this time we can buy, of course, we can also test the waterproof performance of the board, if the waterproof is not good, at this time we should not buy.

But I think the decoration is very watery, so we must pay attention to these problems, so that we can get better, these problems need to attract everyone's attention, because we also hope that the house can be decorated more beautifully, and also hope that this house can meet our minds, so we must choose the right products. It can make everyone think that there are many types of wood boards, so everyone should try to choose some parquet, which is also more high-quality and can be used for a long time.

We usually mop the floor in our lives, so we must buy some flooring that can be waterproof, if we buy products of poor quality, then these products may rot. So you must buy some products with quality assurance, and we can also buy them with acquaintances.

1. Look at the thickness: the thickness of the surface layer of the parquet determines its service life, the thicker the surface board, the longer the wear resistance, the surface thickness of the European parquet is generally required to be more than 4 mm.

2. Look at the material: the parquet is divided into three layers: surface, core and bottom. The surface layer is a wear-resistant layer, and varieties with hard texture and beautiful texture should be selected.

The core layer and the bottom layer are balanced buffer layers, and the varieties with soft texture and good elasticity should be selected, but the most critical point is that the varieties of the bottom layer of the core layer should be consistent, otherwise it is difficult to ensure the stability of the structure of the floor.

3. Look at the processing accuracy: the biggest advantage of the parquet is that the processing accuracy is high, therefore, when choosing the parquet, we must carefully observe whether the splicing of the floor is tight, and there should be no obvious height difference between the two adjacent boards.

4. Weigh the weight: Of course, you should weigh it yourself, and a good floor should not be too light or too heavy. The weight of the floor is too light, mostly because the material of the selected substrate is relatively soft, so the strength will be relatively poor, and the floor is too heavy to deform and crack.

5. Look at the straightness of the floor: high-quality multi-layer solid wood flooring has strict requirements for material selection, process control and factory inspection, and the edges and board surfaces of the finished floors are smooth and straight. Inferior flooring is much rougher, and the edges and board surfaces are generally observed along the length of the floor with the naked eye, and obvious concave or convex or warped can be seen.

6. Look at the appearance: the paint surface of the high-quality floor is full and smooth, rich and natural, the paint film has good transparency, and the physical properties of the appearance can be seen at a glance. The paint surface of inferior flooring is shriveled and obscure, with more exposed paint, bubbling, pinholes, ripples, particles, etc., poor transparency of paint film, blurred texture of surface plate, and obscure appearance of wood.

The decoration project in the home is very heavy, every detail we hope to do the best, after all, the house is to provide us to live for a long time, if there is a problem in one aspect, after the renovation and maintenance, it will waste a lot of money, and even some places are difficult to repair, which will also cause us to trouble, then after the decoration is perfected, it is necessary to choose the home, in the choice of home is also needed to take care of all aspects of the use, and the habitual use of family members should also be taken into accountIf the material is unsafe, it is a great hazard to our human body.

When the floor decoration is also selective, you can choose ceramic tiles or parquet, depending on personal preference is to like which style of decoration, the diversity of ceramic tiles, you can choose a wide range, and the parquet can give us not many patterns, the choice of color is also roughly fixed, if you want to install parquet, you must know how to distinguish its good or bad.

First of all, you need to look at the thickness of the parquet, there are some materials that cut corners will deceive consumers by reducing the thickness, the thickness of the parquet determines the length of service life, the thicker the board, the higher the wear resistance, which proves that the service life will increase, and the solid wood parquet with sufficient thickness is good; The second is the material of the floor, the general solid wood floor is composed of three parts: table, core and bottom, and the existence of these three parts can be assured to buy when choosing, these three parts are to make the material more in line with the installation requirements; Finally, it is necessary to use the rubber material for the floor, some of the rubber material is there a certain formaldehyde content, which is not healthy for our body, and we should pay attention to see whether the manufacturer uses the rubber material that does not meet the standard, so that you can give up the choice.

First of all, it is necessary to see whether the surface of the floor is particularly smooth, but also to see whether the floor is not easy to prevent moisture, gently pat the floor with your hand, whether it is particularly crisp, and also to see whether the pattern of the floor is particularly clear, when you buy, you can see whether the floor has obvious scratches, or the color of the floor is very dull, if it is very dull, it means that the floor is very bad.

It can be identified by color, smell and quality. At the same time, you can also choose a more cost-effective parquet floor, and you should also shop around when buying, and don't be greedy.

In general, it can be distinguished according to the thickness of the solid wood floor and the material of the solid wood floor, generally speaking, the floor with a thickness of 2mm is the best, and at the same time, you must choose some walnut or cherry wood, oak and other materials of the floor, to avoid shoddy business. When buying, you must buy a more reliable brand and understand the ** of solid wood flooring.

First, the intrinsic quality of parquet.

The intrinsic quality is the key indicator of parquet, but it is difficult to determine intuitively, and it must be tested by means of testing, therefore, it is necessary to observe its test report, which is as follows:

1. Formaldehyde emission of parquet.

This problem exists in the plywood flooring made of urea-formaldehyde resin glue, and if the amount of formaldehyde released into the air is too large, it will be harmful to the human body.

China has stipulated that the concentration of formaldehyde in the air in public places shall not exceed milligrams per square meter.

If a pungent formaldehyde smell has been smelled during the laying process, the formaldehyde concentration in the air has exceeded the standard.

For the determination of formaldehyde concentration of parquet, perforated extraction method is mainly used in China.

The resulting "perforation value" indicates the amount of formaldehyde that can be released in 100 grams of product.

If the "perforation channel" is about 9 milligrams per square meter or below, it can basically meet the formaldehyde concentration standard stipulated by the national environmental protection regulations.

If it is less than 30 milligrams per square meter, it generally meets the technical standard of class B.

2. The moisture content of parquet.

The moisture content usually reaches about 12%, which is basically qualified (different regions, the implementation of moisture content standards is different).

3. The gluing performance of parquet.

Parquet is made of adhesive-coated panels when they are manufactured, so the quality of gluing directly affects the use effect and life.

The quality of the glue can be reflected by two performance indicators, namely the impregnation peel and the strength of the glue.

These two indexes are measured after the specimen is treated in water with a certain temperature, the lower the impregnation peel value, the better, and the higher the gluing strength value, the better.

The quality of parquet is mainly considered from the following aspects:

Second, the appearance quality of parquet.

The surface of the parquet should be observed:

1. Whether the surface paint is glossy, whether the paint film is plump and uniform, whether there are needles and granules, whether there are indentations and planing marks.

2. Indicate whether there are obvious defects in the material. The surface of the wooden floor should not have defects such as decay, dead joints, knots, insect holes, cracks, and skin clamping.

3. The surrounding tenon and groove are complete.

3. Whether the dimensional tolerance of the parquet meets the requirements.

1. Whether the specification and size tolerances of parquet are the same as those of the product introduction;

2. Whether the tenon and size of the parquet are tight and smooth, you can assemble them on the flat glass table top or ground by spot-checking multiple floors to see the degree of tightness of the combination and touch whether the surface is smooth.
