Classification of flooring

There are many classifications of flooring, according to the structure: solid wood flooring, laminate wood flooring, three-layer solid wood composite flooring, bamboo flooring, anti-corrosion flooring, cork flooring and the most popular multi-layer solid wood composite flooring, etc.; according to the classification of use: flooring for household occasions, flooring for commercial occasions, anti-static flooring, outdoor flooring, flooring for stage dancing, flooring for sports stadiums, flooring for athletics, etc.; according to Environmental protection grade classification: E1 grade flooring, E0 grade flooring, JAS star standard F4 star flooring, etc. Chinese market some special propaganda geothermal special flooring, in fact, as long as the substrate is stable, not cracked, not deformed, high environmental performance, can heat preservation and thermal conductivity, even pure solid wood flooring, floor heating can be used.

Solid wood flooring

Solid wood flooring is the wood is dried, processed to form the ground decorative materials. It has the characteristics of natural pattern, comfortable footing and safe to use. It is the ideal material for bedroom, living room, study and other floor decoration. The decorative style of solid wood has a natural texture and is more environmentally friendly. The weakness of solid wood flooring is the poor durability to moisture and sunlight, moisture makes the natural wood swell, and dry but will shrink, thus leading to gaps and even buckling and warping. Underfloor heating use of solid wood flooring processing selection requirements are great, so the market, solid wood floor heating special not no, but very little.

The advantages and disadvantages of solid wood flooring, the price of the difference, not only from the different species to judge, but also from the hardness of the paint film, paint plate surface wear resistance, paint film adhesion and moisture content indicators and so on all aspects to see.

Solid wood flooring grade: national division: superior, first-class products, qualified products three grades, superior quality is the highest.
Environmental protection grade: the state did not do the corresponding standard division.
Wear-resistant grade: superior solid wood flooring finish surface wear index ≤ 0.08g/100r; first-class products ≤ 0.10g/100r; qualified products ≤ 0.15g/100r.
Film hardness: is a reflection of the strength of the solid wood flooring surface paint film, and solid wood flooring materials and the thickness of the paint film itself, the material has a close relationship, the national standards provide for superior solid wood flooring paint film hardness indicators for 2H level; first-class products and qualified products ≥ H.

Film adhesion: reflects the strength of paint adhesion to solid wood flooring, the indicator does not pass also means that the floor paint quality is poor, in use may cause the paint cracking or even peeling, the same impact on the service life of the floor. The national standard stipulates that the superior quality solid wood flooring paint film adhesion indicators for 0 ~ 1 level; first-class products ≤ 2 level; qualified products ≤ 3 level

Moisture content index: refers to the solid wood flooring in the sales area is not unpacked or just remove the packaging state of the moisture content. This indicator is not qualified will cause the floor in use deformation, warping, arching or off seam and other phenomena, affecting the beauty and use of performance. National standards specify the moisture content index of solid wood flooring is 7% to the equilibrium moisture content of the place of sale.

Color difference: this is very critical, many disputes of solid wood lies here. People on the natural color difference of solid wood flooring demanding consistency is unrealistic. Solid wood flooring must have color difference, color difference is natural and inevitable, which is determined by the natural properties, therefore, the state in the development of relevant standards, there is no requirement for color difference.

Laminate hardwood flooring

The official scientific name of laminate wood flooring: dipping routed paper laminated wood flooring. It is crushed in the logs, filled with glue, preservatives, additives, by the hot press high temperature and high pressure pressing treatment, so it breaks the physical structure of the logs, to overcome the weakness of the poor stability of the logs. Laminate flooring has high strength, uniform specifications, high wear coefficient, anti-corrosion, anti-moth and good decorative effect, overcoming the problem of scar knots, insect eyes and color difference on the surface of the logs.

Laminate flooring

Very wear-resistant, beautiful pattern, stable structure, economical and applicable
No need to paint and wax, wide range of use, easy to take care of, is the most suitable for modern family life rhythm of the floor material. In addition, laminate flooring is a good environmental protection material because of its high wood usage rate.

The environmental protection grade of laminate flooring and multi-layer solid wood flooring is the most strict national regulations.
(The new national standard GB/T18102-2007) for E1 and E0 two grades, JAS star standard F3 star flooring F4 star flooring for the world’s most stringent way to detect formaldehyde, but this is the Japanese national standard established by the Japanese government. f4 star flooring can reach close to the formaldehyde emissions of solid wood. Most of the domestic flooring manufacturers have some difficulty in production and have not joined our national standard for the time being. So to reach this level of flooring, you must have the certification of the General Administration of Quality Supervision of China and the National Standards Committee of China. The above-mentioned units received the application of the manufacturers, a long time assessment and testing, after meeting the standards of the common certificate of recognition, in order to be listed and sold in China according to the standard of F4 star flooring.

Solid wood laminate flooring.

Solid wood composite wood flooring is divided into three layers of solid wood composite flooring, multi-layer solid wood composite flooring, new solid wood composite flooring three, because it is made of different species of plates staggered lamination, so overcome the shortcomings of solid wood flooring one-way homogeneous, dry shrinkage and wet expansion rate is small, with good dimensional stability, and retain the natural wood grain of solid wood flooring and comfortable footing. Suitable for consumers who like the natural beauty of solid wood flooring, but are afraid of the instability of solid wood flooring.

Solid wood laminate flooring and laminate wood flooring stability and solid wood flooring aesthetics in one, and has the advantage of environmental protection, the performance value is relatively high new solid wood laminate flooring, should be the trend of the development of the wood flooring industry.

1.Three layers of solid wood laminate flooring.
Structure.
Role: good wood elasticity, comfortable footing, good warmth, natural color, stable structure represents the international flooring has been popular trends

2.Solid wood composite flooring environmental protection grade division and laminate flooring grade the same, divided into E1 and E0 two grades. Because the market price between laminate and solid wood prices, environmental protection to do E0 cost will be close to the price of solid wood flooring, so the market to environmental protection E1 grade. But the merchants in order to sell goods, often closed-mouth environmental standards, said this is solid wood, mixed concept.

Bamboo wood flooring

Is made of bamboo after treatment of the floor, both rich in the natural beauty of natural materials, but also the advantages of wear-resistant and durable, and moth-proof, shock-resistant. Bamboo flooring is warm in winter and cool in summer, moisture-resistant and wear-resistant, easy to use, especially to reduce the use of wood, play a role in protecting the environment. Bamboo flooring according to the structure is divided into, laminated, vertical pressure, work-type pressure, these manufacturing methods, environmental protection grade division and laminate flooring grade the same, divided into E1 and E0 two grades. Other standards and solid wood flooring the same.

Cork flooring

Cork is the protective layer of China oak wood, namely the bark, commonly known as cork oak. The thickness of cork is generally 4.5 mm, high-quality cork up to 8.9 mm. Compared with solid wood flooring, cork flooring is better in environmental performance, moisture resistance.
There are three main types of cork flooring.

① Pure cork flooring. Thickness in 4, 5 mm, from the color of the pattern is very rough, primitive, and no fixed pattern. Its biggest feature is made of pure cork, its installation using paste type, that is, with special glue directly on the ground, the construction process is more complex, the flatness of the ground requirements are also higher.

②Cork silent flooring. It is a combination of cork and laminate flooring, is in the ordinary laminate flooring of the bottom layer added a layer of about 2 mm of cork layer, its thickness can reach 13.4 mm. When people walk on it, the bottom layer of cork can absorb part of the sound and play the role of sound reduction.

③Cork flooring. From the profile there are three layers, the surface layer and the bottom layer are refined from natural cork, the middle layer sandwiched a piece of HDF board with a lock, the thickness can reach 11.8 mm, the surface layer and the bottom layer after special treatment both elasticity and strength, expansion and contraction and HDF board to maintain the same, greatly enhancing the stability of this floor. The inner and outer layers of cork can achieve a very good silent effect. The surface layer of cork is also coated with special advanced flexible lacquer, which can reflect the texture of cork and also play a very good protective role. At the same time, this kind of flooring uses the locking technology, fully guarantee the floor splicing tight and flat, can directly adopt the suspension paving method.

PVC plastic flooring

PVC plastic flooring refers to the flooring produced by using polyvinyl chloride material. Specifically, it is made of PVC and its copolymer resin as the main raw material, adding fillers, plasticizers, stabilizers, colorants and other auxiliary materials, on a continuous sheet substrate, produced by the coating process or by calendering, extrusion or extrusion process. It is a new type of light body flooring material that is very popular in the world today, also known as “light body flooring material”. It is a popular product in Europe, America and Asia, Japan and Korea, popular abroad, from the early 80s into the Chinese market, in large and medium-sized cities in China has been widely recognized, the use of very wide, such as schools, hospitals, office buildings, factories, transportation systems, home furnishings, stadiums and other places.
