What are the details that should not be overlooked when choosing Higa laminate flooring?

When people choose laminate flooring, most of them will only pay attention to its color and quality, and often ignore some details, such as wear-resistant layer, substrate, etc.

1. The wear-resistant layer is the embodiment of the durability of the laminate floor.

The degree of wear resistance of the wear-resistant layer depends on the processing technology of the laminate flooring, and the wear resistance of the general household laminate flooring is greater than 6000 rpm. But there are also good ones, such as Higa laminate flooring, which is affected by the processing technology, and the wear resistance and stain resistance are well reflected. And Higa laminate flooring has a significant feature:

The brighter it gets, no matter how long it is used, it will not stain, while the floor with poor wear resistance quality will gradually stain and no longer shine after a period of use.

The reason is that Higa flooring has the country's top floor processing factory, Higa laminated flooring in the production process, through 240 ° of high temperature hot pressing of the wear-resistant layer, substrate, pattern paper, balance paper pressed together, the general enterprise due to the processing conditions, the melted wear-resistant layer will produce static electricity at the moment of separation from the pressing plate, and these static electricity will not be completely cured of the wear-resistant layer glued, so that the surface of the wear-resistant layer forms many tiny pinholes, so after only a period of time in the floor, The stain then penetrates under the wear-resistant layer of the floor, forming a phenomenon of staining on the surface of the floor. On the contrary, Higa laminate flooring does not form static electricity in the processing process and does not produce surface voids, so the floor will naturally become brighter and brighter.

2. The substrate is the embodiment of environmental protection of laminate flooring.

At present, the standard value of the national E1 level is: E1 level, and the standard value of the national E0 level is: E0 level.

Higa in art flooring has reached E0 level, and the quality of the substrate not only affects the environmental protection coefficient, but also determines the first grade of laminate flooring in the market, the cost price of products with low formaldehyde content is relatively high, and the opposite is slightly lower, generally the environmental protection of the floor can be judged by the product inspection report presented by the merchant.

However, you can also choose to buy in the ** season, like the previous Higa flooring 315**, its high-quality laminate flooring is only 69 yuan, this time miss the friends do not be sad, pay attention to the May Day, maybe there will be a bigger surprise!

1.Thickness: The thickness of the floor should be 8 mm. The floor with a thickness of only 6 mm is mostly used temporarily for exhibitions and other activities, although it is low, the life span is less than 8 mm thick.

2.Wear-resistant revolutions: It is an important indicator of the strength of the floor, which is divided into initial revolutions (IP), average revolutions (AT), and final revolutions (ET).

3.Water resistance: Different plates can be soaked in water for 24 hours to check whether the surface layer is peeling and expanding.

4.The processing quality of the mouth of the floor and the ficus should be checked, as well as whether the coating of the moisture-proof and anti-corrosion material on the back of the board is full.

There are three factors to consider when choosing laminate flooring: the number of abrasion resistance, formaldehyde content, and the expansion rate of the water absorption thickness.

The number of abrasion resistant revolutions is an important indicator of laminate flooring. Objectively speaking, the higher the number of wear resistance, the longer the service life should be, but the level of wear resistance value is not the only criterion for measuring the service life. Under normal circumstances, the wear-resistant rotation of composite flooring reaches 10,000 revolutions, and the product of less than 10,000 revolutions may be damaged to varying degrees after 1 or 3 years of use.

Formaldehyde content is an indicator that is not taken seriously by consumers. Therefore, many consumers are troubled by pungent odor after construction, which is caused by excessive formaldehyde content. According to the European standard, the formaldehyde content of every 100 grams of floor shall not exceed 9 mg, and more than 9 mg is a substandard product.

Therefore, this indicator is related to the key indicator of whether the products we choose are harmful to the body.

If the expansion rate of the water absorption thickness is not qualified, the board will bulge and deform. This index can be regarded as qualified within 3, otherwise, the floor will bulge and deform when it encounters moisture or relatively high humidity and poor sealing around the floor, which will affect normal use.

Experts especially pointed out that when consumers buy composite flooring, they should carefully inquire about the difference between different grades of composite flooring, and remember the selected grade of products, and should accept whether the packaging is consistent after picking up the goods.

The key to choosing laminate flooring is to look at nine elements:

1. Look at the brand: well-known brands can ensure product quality and after-sales service.

2. Look at the material: normal laminate flooring should be based on high-density fiberboard.

3. Look at the thickness: the international standard thickness is 8mm, and the thickness below this is not strong.

4. Look at the surface wear resistance speed: the initial wear resistance value of the household floor surface is generally above 6000 rpm.

5. Look at the amount of formaldehyde released: the standard for green building materials stipulated by the international environmental protection organization is not higher than 9mg 100g.

6. Look at after-sales service: 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.

7. Look at the moisture-proof measures: whether there is a special moisture-proof floor mat, whether there is a thick moisture-proof layer on the floor, whether the glue is a special floor waterproof glue, etc.

8. See if it is fair: compare the quality of the floor and whether its after-sales service is worth the money.

9. Look at the packaging: If it is an imported commodity, there should be a Chinese logo and a customs inspection certificate.

The landlord said that Higa, their products are not bad, the quality is quite good, and the cost performance is also high.

Whether the harder and more durable laminate flooring is, I believe everyone is puzzled about it, so I will analyze it in detail for you next.

It is often seen that two floors are knocked against each other to carry out a hardness comparison test, which shows that the brand's flooring is more durable. Many consumers also agree with the logic of this type of test method, believing that the harder the laminate flooring, the better the quality and the more durable the product.

To judge whether the laminate flooring is durable, it is necessary to look at a number of indicators: surface wear resistance; The density (i.e. hardness) of the floor, which is related to the impact resistance of the floor; The water absorption and expansion rate of the floor, which determines the water resistance of the floor; The internal bonding strength, that is, to see whether the floor is layered, the strength of the floor with layers will be reduced. These factors combine to affect the durability of the floor, and only when the coefficients of several other indicators are the same, can it be proved that the harder the sock board is, the more durable it is.

In recent years, the thickness of laminate flooring has been increasing, from the mainstream thickness of 6 mm to 12 mm now, and 13 mm and 15 mm thick floors have appeared on the market. Many consumers also follow the trend of believing that the thicker and heavier the floor, the stronger and more durable it will be.

The service life of laminate flooring depends to a certain extent on the quality of the floor surface, whether it is a thick floor or a thin sail board, once the surface is worn out, it cannot be used. Thicker floors have a good foot feel and are costly. Therefore, there are many determinants that affect the quality of laminate flooring, not just the thickness.

Product**In the same case, it is better to buy 12 mm thick brand flooring than 15 mm thick miscellaneous brand flooring. In addition, due to the huge differences in product cost, process and production technology, the service life of miscellaneous brand thick plate may not be as long as that of large brand thin plate.

Single lock, double lock, triple lock, quadruple lock" ......In the propaganda of manufacturers, the number of locks on the floor is rising, and many manufacturers also use this as a selling point, implying that the more locks, the stronger the floor will be after installation.

The locking floor is a structure that connects the floor plates by the physical force of the lock. Due to the locking force of the locking floor, the floor will extend to the surroundings as a whole with the temperature change, avoiding local uplift and solving the internal deformation problem of the floor. In fact, whether the floor is firmly connected or not depends not on the number of locking steps, but on the range of changes in ambient humidity.

For the northern region, the summer is more humid, the winter is drier, if the floor is expanded in summer, the room on both sides of the symmetrical discharge of heavier family car excitation, the air is particularly dry in winter, the floor is therefore dry and shrinking, even if the three locks can still pull the lock open, so the lock floor needs to be used with the environment.

The choice of laminate flooring needs to understand several concepts first, first of all, laminate flooring is composed of a surface wear-resistant layer, a decorative layer, a buffer layer, a wood-based panel substrate, and a balance layer. In terms of technology, it is impregnated and dried by urea-formaldehyde resin and melamine resin, and the buffer layer paper and balance layer paper are impregnated and dried by phenolic resin, and then stacked with the substrate to form a blank and then hot-pressed into a plate, and the cooled plate is made by longitudinal and horizontal sawing and longitudinal and horizontal tenoning.

In terms of material selection, the selection of surface wear layer and substrate is more important. The substrate of the laminate flooring usually uses high-density fiberboard, and the color of the high-quality substrate should be the color of natural pine and poplar, exuding a fresh fragrance, not pungent, not dazzling, looking very delicate, very smooth and flat to the touch, and the cross-section is very evenly distributed after cutting, and there is no obvious distribution; The base material of poor quality is dark brown due to the selection of logs or miscellaneous trees and shrubs that do not peel in the production process, which exudes a too pungent smell and is very rough to the touch. The wear-resistant rotation of the wear-resistant layer is one of the physical indicators of whether the laminate floor is qualified.

The aluminium oxide wear-resistant layer (commonly known as synthetic diamond) is hard and wear-resistant, and this index is usually measured by the wear-resistant value. The thickness of the wear-resistant layer is general, but the thickness does not represent the wear resistance, but to contain aluminum oxide per square meter to illustrate, generally there are several kinds of grams, the higher the aluminum oxide content, the higher the wear resistance. The wear resistance of the composite floor is assessed by the standard wear-resistant revolutions, and the general wear-resistant revolutions above 6000 revolutions can fully meet the needs of home decoration.

The choice of laminate flooring not only needs to consider the substrate and surface, but also takes into account the production process, which can be seen from the concave and convex groove process of laminate flooring, laminate flooring is divided into two kinds of flat mouth and tongue and groove from the occlusion method. The convex groove die-cutting is regular, fine and uniform, and the convex groove protrusion part and the recessed part of the groove have sufficient length of laminate flooring to be easy to install, and can also prevent the floor from deformation. If the floor convex groove die-cutting is not precise enough, the convex groove groove is loose and wide, although it is easy to install, but after the floor is stepped on and stressed, the convex groove shakes in the groove, which will quickly cause the glue to peel off, and form a gap that is not easy to find with the naked eye at the floor interface.

The floor with cracks can easily allow water, moisture, and dust to take advantage of the gap, resulting in the floor expanding, deforming, and warping.

1. Look at the wood grain: the high-grade laminate flooring has high texture clarity, the color is more realistic, and even the wood grain scars and texture details are almost the same as the real wood. The poor-quality wood floors have stiff and rigid prints, and the texture is rough and blurred.

Consumers can touch the surface of the wood floor with their hands, and a good laminate flooring subverts the flat effect of the ordinary floor in terms of wood grain and touch, and the three-dimensional sense is stronger.

2. Look at the bar code: for regular laminate flooring, the back of the floor will not only be printed with the brand's trademark, but also the model of the floor, the number of wear-resistant revolutions and the environmental protection level, so that consumers can see it at a glance.

3. Smell the smell: The laminate flooring with the base material is good and the laminate floor will exude a woody fragrance. Laminate flooring with a bad substrate will emit a strong pungent odor.

The author randomly picked up two pieces of wooden flooring and put them in front of his nose, and the pungent smell of one of them made the author immediately frown. Consumers may wish to smell the smell of the floor when purchasing, and do not buy inferior flooring.

4. Weight: A good laminate floor has a high density, a delicate and uniform texture of the cross-section, and small and compact particles. Poor quality laminate flooring with large and sparse cross-section and an extremely rough surface.

Then use your hands to weigh it, a good parquet due to its high density, the feel is also heavier.

When purchasing laminate flooring, you should pay attention to the following aspects:

Proof that the material is environmentally friendly. Laminate flooring contains a certain amount of formaldehyde, if the release exceeds the standard will be harmful to the human body, do not believe in the purchase guide "zero formaldehyde" statement, merchants will generally provide environmental protection certificates, inspection reports and other supporting materials, you must pay attention to check when purchasing.

Pay attention to the number of wear-resistant revolutions. Laminate flooring is not the higher the number of revolutions, the better, household laminate flooring can be more than 4000 revolutions. It looks natural and feels comfortable on your feet.

The base material does not fall ash. When choosing laminate flooring, the whiter the base, 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.
