What standard should the wear resistance of laminate flooring meet?

The wear resistance directly affects the service life of the product. The number of wear-resistant revolutions is the expression of the wear-resistantness, generally the number of revolutions, the higher the wear-resistant revolution, the better the wear-resistant performance of the product. According to the national standard, three samples are tested with 180 mesh sandpaper, and one piece of sandpaper is converted every 500, and the number of revolutions when there is clearly visible wear in three quadrants of A, B, C, D is the initial wear value (IP value).

The wear value can be divided into initial value (IP), final value (FP) and average value (AT) according to different test methods, FP is often more than 2000 3000 revolutions larger than IP, and AP value is the average value of IP and FP. Generally, the test results show that the floor with an AP value of more than 6000 rpm is suitable for home use, and the AP value of more than 9000 rpm is suitable for use in public places.

National standard: 4000 rpm for household type II, no less than 38 grams of wear-resistant paper, 6000 rpm for household type I, no less than 45 grams of wear-resistant paper, 9000 rpm for commercial type, not seen in the general market.

Ask how much aluminum oxide is on the surface of the business, and the amount of aluminum oxide is more wear-resistant, generally more than 28 grams.

The national standard is 4000 rpm, and some powerful ones can reach 9000 rpm, but the turn is too high and the foot feeling is not good.

Home improvement office is basically above 6000 rpm!

That brand of laminate flooring is cost-effective.

Three levels. According to the national grade division, it can be divided into three grades: excellent products, first-class products and qualified products.

According to the national environmental performance level, it can be divided into E2 level, E1 level and E0 level, of which the environmental protection level of E1 wood floor can be called environmental protection flooring, in addition to Japan's F4 star division and so on.

According to the wear-resistant grade, it can be divided into engineering level 1 (wear-resistant rotation is greater than 9000 rpm), household first-class (wear-resistant rotation is greater than 6000 revolutions) and household second-class (wear-resistant rotation is greater than 4000 rpm), and the grade is limited to laminate flooring according to the wear resistance.

Solid wood flooring has no division of wear resistance.

The level of the wear-resistant rotation depends on the content of aluminum oxide in the wear-resistant layer of the laminate flooring, if the aluminium oxide content is high, the wear-resistant rotation value obtained during the test will be high. Because aluminum oxide is a mineral, if the content is too high, the wear-resistant paper will lack toughness, and the surface will be brittle, which will lead to the reduction of the clarity of the decorative layer; At the same time, the quality of decorative paper, the hardness and wear resistance of the knife are also higher, and the cost is higher, so the choice should be considered in combination with the environment and the cost performance of the product. Generally speaking, flooring above 4000 rpm can be suitable for home use, and more than 9000 rpm is suitable for use in public places.

Compared with solid wood flooring, the wear layer on the most surface of laminate flooring is specially treated to achieve high hardness, even if it is scraped with a sharp hard object such as a key, it will not leave marks. The biggest advantage of this advantage is that you no longer have to shrink your hands and feet to protect the floor in your daily life. Moreover, it has higher flame retardant performance, strong pollution and corrosion resistance, and good compressive and impact resistance.

Cost-effective (cheap): Laminate flooring is composed of wear-resistant layer, decorative layer, substrate and balance layer. Its wear-resistant layer, decorative layer and balance layer are manually printed, and the base material is made of fast-growing forest wood, which is cheaper than that of solid wood flooring, and can be produced on a large scale, which is relatively cost-effective.

The upstairs answer is ruthlessly correct, the country requires the laminate floor to reach more than 6000 rpm, which is equivalent to the European AC3 standard, more than 10,000 to reach the AC4 standard, AC5 is higher, and there are very few domestic that can reach more than 6000 rpm, generally the highest value can reach 6,000, and the lowest value is difficult to say, the lowest value reaches more than 6,000, I know that Fillinger can achieve, the icon is home level 2.

That's all I have to say:

The market can be divided into 5 grades, which are formulated with reference to the European standard.

The aluminium oxide content and the number of wear-resistant revolutions are equivalent to the European standard.

33G 4000 2500 rpm AC1-21

38G 6000 4000 rpm AC2-22

45g 9000 6000 rpm ACA3-23

62G 15000 9000Z to A4-32

76G 18000 12000 rpm AC5-33

Girl, you're asking too professionally. For the average consumer, the wear resistance index does not need to be studied.

I've never done anything specifically about it, and we usually tell our customers that the abrasion index is 7200 rpm.

Anyway, it's all manufacturer's data, and I've never counted whether it can really reach 7,200 revolutions!

The number of wear-resistant revolutions of the national standard floor.

The number of wear-resistant revolutions is the expression of the wear resistance of the floor, which is divided into three kinds according to the national standard: IP, AT and FP, and the IP is the initial wear-resistant value, which refers to the number of revolutions when the wear point begins to appear after the wear test on the floor surface with international standard wear-resistant paper.

FP is the final wear resistance value, which refers to the number of revolutions when the wear layer on the surface of the floor is completely worn. FP tends to be more than 2000 3000 rpm larger than IP, and AT is the average wear value between the two.

Generally, the test results show that the floor with an AP value of more than 4000 rpm meets the household level 2 standard, the floor with an AP value of more than 6000 rpm meets the household level 1 standard, and the floor with an AP value of more than 9000 rpm meets the commercial standard.

The standard stipulates that the average value of the assembly height difference is less than or equal to the maximum value of the assembly height difference, which occupies a considerable weight in the cost performance of the wood floor, which is directly related to the service life of the floor.

The wear resistance value of laminate flooring is one of the most important indicators of laminate flooring and is the biggest variable that determines the service life of laminate flooring. However, the different opinions of merchants on the wear-resistant value make consumers at a loss to ......Where do these values come from? How can consumers know whether the wear value mentioned by the merchant is true or false?

In fact, it is very easy to know this variable, find a 360 mesh sandpaper on the spot and experiment, start grinding according to the number of revolutions said by the merchant, a back and forth is counted as two revolutions, and when the surface of the floor begins to wear, calculate how many times you grind.

Magical Adventures to the fullest with the Practical Handbook on the Internet.

At this time, the number of revolutions obtained is the initial wear value of the floor, so keep grinding! Grinding to a certain number of revolutions, you will find that there is no aluminum oxide surface in the place where it is grinded, and then calculate, how many revolutions have been grinded, then you get the final value of the floor. Typically, the final value is much higher than the initial value.

Perhaps, some merchants will also tell you that he is the median value, it doesn't matter, and then calculate the average of the two values you got earlier, and that's it!

In the course of the experiment, the floors whose surfaces are quickly worn out must be those without a wear-resistant layer; The floor that appears to be worn before 6000 rpm may have a wear-resistant layer, but it must be a domestic substandard product; Products above 6000 rpm can be called laminate flooring in line with the national standard, generally speaking, the initial wear resistance value of imported laminate flooring is above 9000 rpm.

The number of revolutions of laminate flooring is the expression of its wear resistance, which is generally expressed in revolutions.

The national standard stipulates that the commercial grade is greater than or equal to 9000 rpm, the household grade 1 is greater than or equal to 6000 rpm, and the second grade is greater than or equal to 4000 rpm.

An important indicator of the surface performance of laminate flooring is the number of wear resistance, but it is not the only indicator. Whether the laminate flooring is durable also depends on the impact resistance, scratch resistance, water absorption expansion rate, the internal bonding strength of the floor, and the resistance to pollution and smoke.

The wear resistance directly affects the service life of the product, and the higher the number of wear resistance, the better the wear resistance of the product. But not all floors wear resistance the higher the better, according to the overall effect of the floor to achieve, the wear-resistant only mountain orange of the floor and the material is also closely related.
