Good materials, in order to have good quality, good equipment to produce first-class products, as the saying goes, do not know the goods, goods than goods, goods than the three do not lose, all about the size of the manufacturer. The ability of the equipment to operate will help you further understand the quality of the product.
In the specific purchase, you can refer to the following four points:
1, surface wear resistance
This indicator is selected according to the use of the occasion, the family generally has more than 6,000 revolutions, and more than 9,000 revolutions in public places. There are four main types of wear of the laminate flooring, while the wear-resistant paper (aluminum oxide content) is about 30g, its abrasion resistance is about 4000 rpm and its content is 38g, its wear resistance is about 5,000 rpm, and its content is about 44g. About 9000 rpm, content 60 grams, wear-resistant about 19,000 rpm.
Detection method: In the optional option, in the absence of a machine test, as long as a continuous use of a No. 0 sand skin floor surface friction 50 times, if no traces, that has reached 5,000 or more, general specification manufacturers, outside the product On the packaging, it is noted that the implementation of the game, resistance to the number of revolutions.
2, free formaldehyde content:
In any building material with viscose, it contains a certain amount of formaldehyde. When the formaldehyde is excessive, the human body is in danger. If the human body is exposed to a high concentration of formaldehyde for a long period of time, there is a danger of cancer. The national standard is ≤1.5mg/L.
Test method: What can I do if I cannot detect formaldehyde content in the field? Teach you three tricks: a look at the test report, whether the national inspection-free products, general export product manufacturers can reach international standards. The smell of the second smell of a good substrate wood odor is not pungent, wooden standard is very delicate, self-illumination, the current domestic use of large Asian substrate (national first-class enterprises, national exemption) will be the first choice. The third is to look at the price, according to the authoritative statistics of the Home Forestry Bureau home-made laminate flooring is mostly between 70-160 yuan, less than 70 yuan (except preferential activities) generally used materials and processing on the number of problems.
3, swelling degree of water absorption:
The more the indicator is, the more the floor is easy to swell, and the material density is about low, and the national standard is ≤10%.
4, internal bonding strength:
The greater the strength, the tighter the bond between the layers of the wooden floor. The state stipulates that this indicator should be more than 1Mpa, generally medium and high density substrates, Bai Rui environmental-friendly substrates, and the degree of close bonding is up to the standard.
