Laminated flooring is one type of flooring. However, composite flooring is artificially changed to the natural structure of flooring materials to achieve a floor with certain physical properties that meet expected requirements. Composite flooring often refers to laminate wood flooring and solid wood composite flooring in the market.
However, the term composite flooring does not exist in professional terminology and national industry standards. Floor, the surface layer of the ground or floor of a house. Made of wood or other materials. Laminated flooring is one type of flooring. However, composite flooring is artificially changed to the natural structure of flooring materials to achieve a floor with certain physical properties that meet expected requirements. The general classification of floors is: According to structure, they include: natural landscape and feng shui flooring, solid wood flooring, laminate flooring, solid wood composite flooring, PVC flooring, bamboo flooring, cork flooring, etc.; according to use, they include: household flooring, commercial flooring Flooring, anti-static flooring, outdoor flooring, flooring for stage dance, flooring for sports halls, flooring for track and field, etc.; classified according to environmental protection levels: E1 level flooring, E0 level flooring, F4 star flooring according to JAS star environmental standards etc.
Chinese name Composite flooring Purpose Home floor laying material Properties Building materials Materials: Wood, organic fiber, inorganic fiber, etc.
laminate flooring
Laminated wood flooring is a popular flooring material in recent years. Official scientific name: Impregnated paper laminated wood flooring. It is made by crushing the logs, adding glue, preservatives, and additives, and pressing them with high temperature and high pressure using a hot press. Therefore, it breaks the physical structure of the logs and overcomes the weakness of the poor stability of the logs. Composite flooring has high strength, uniform specifications, high wear resistance, anti-corrosion, moth-proof and good decorative effect, and overcomes the problems of knots, insect holes and color difference on the surface of logs. Composite wood flooring does not require painting or waxing, has a wide range of uses and is easy to care for. It is the most suitable floor material for the pace of modern family life. In addition, composite flooring has a high wood usage rate and is a good environmentally friendly material.
Environmental protection grade classification of laminate flooring
The national regulations on the environmental protection level of laminate flooring are the most stringent. (The new national standard GB/T18102-2007) has two levels: E1 and E0. The JAS star standard F3 star floor and F4 star floor have the most stringent formaldehyde detection method in the world. F4 star Flooring can achieve a formaldehyde emission level close to that of solid wood. Most domestic flooring manufacturers have certain difficulties in production and have not yet joined my country's national standards. Therefore, floors that reach this level must be assessed and tested by the State Administration of Quality Supervision and the National Standards Committee. After meeting the standards, they will be certified and approved before they can be sold on the market.
Parquet:
Solid wood composite flooring is divided into three types: three-layer solid wood composite flooring, multi-layer solid wood composite flooring, and new solid wood composite flooring. Since it is made of sheets of different tree species laminated together, it overcomes the shortcomings of solid wood flooring being unidirectional. It has a small dry shrinkage and wet expansion rate, good dimensional stability, and retains the natural wood grain and comfortable foot feel of solid wood flooring. Solid wood composite flooring and laminate flooring combine the stability of solid wood flooring with the aesthetics of solid wood flooring, and are environmentally friendly and a new type of solid wood composite flooring with high performance and value. This should be the development trend of the wood flooring industry.
Environmental protection grade classification of solid wood composite flooring
The same level as laminate flooring, divided into two levels: E1 and E0. Because the market price is between the price of laminate and solid wood, if the floor is environmentally friendly and E0, the cost will be close to the price of solid wood flooring, so the market is mainly environmentally friendly E1 level.
PVC composite floor
Multi-layer composite PVC floor means that it has a multi-layer structure, usually 4 to 5 layers of structures are laminated. It generally has a wear-resistant layer (including UV treatment), a printed film layer, a glass fiber layer, and an elastic hair layer. Bubble layer, base layer, etc.
Wear resistance
This is an important indicator of the quality of laminate flooring. Objectively speaking, the higher the wear resistance, the longer the floor should be used, but the wear resistance is not the only criterion for measuring the service life of the floor. Under normal circumstances, composite flooring has a wear-resistance of 10,000 revolutions, which is considered a high-quality product. Products with less than 10,000 revolutions may experience varying degrees of wear after 1 to 3 years of use.
Swelling rate after water absorption
This indicator can be considered qualified if it is within 3%. Otherwise, the floor will deform when it encounters moisture, or when the humidity is relatively high and the surrounding sealing is not tight, affecting normal use.
Formaldehyde content
This is a key indicator related to whether the products we choose are harmful to the body, but it is easily ignored by consumers. According to European standards, the formaldehyde content of flooring shall not exceed 9 mg per 100 grams. If it exceeds 9 mg, it is an unqualified product.
Floor thickness
The thickness of the flooring on the market is generally 6 to 12 mm. When choosing, the thickness should be thicker. The thicker the thickness, the longer the service life will be, but at the same time, the actual needs of the family must be considered.
Assembly effect
You can take two floor samples and assemble them to see if they are neat and tight after assembly.
floor weight
Flooring weight is primarily determined by the density of its base material. The base material determines the stability of the floor, as well as various indicators such as impact resistance. Therefore, the better the base material, the higher the density, and the heavier the floor.
Formal certificates and inspection reports
When consumers choose flooring, they must find out whether the merchant has relevant certificates and quality inspection reports. Relevant certificates generally include floor origin certificates, European Laminated Flooring Association (EPLF) certificates, ISO9001 international quality certification certificates, ISO14001 international environmental protection certification certificates, and other related quality certificates.
Environmental performance
A common concern among consumers is the environmental performance of floors. When choosing a floor, the first consideration should be the environmental protection of the product, followed by other properties of the product, as well as price. You can confirm whether the floor is an environmentally friendly product by checking whether there is a relevant green environmental certificate.
After-sales service
Laminated flooring generally requires professional installers to use special tools to install, so consumers must ask whether the merchant has a professional installation team and whether it can provide a formal warranty certificate and warranty card.
Faced with the many brands of laminate flooring products on the market, consumers do not have to be dazzled. As long as they start from several aspects such as quality, color, environmental performance, and after-sales service, they can choose the floor that meets their needs.
Correctly identify floor life and cost performance:
1) Laminate flooring
Manufacturers generally advertise that the quality is guaranteed for 10 to 15 years, and I have even seen lifetime guarantees. In fact, the life of laminate flooring is mainly determined by the quality of the surface wear-resistant layer and the quality of the base material. If you choose a better wear-resistant layer and the water resistance of the base material is also better, there will be no problem in household use for more than 20 years. The price is quite confusing, ranging from a minimum of more than ten yuan to more than 500 yuan. The main factors are environmental protection performance, wear resistance, flame retardant performance, and water swelling performance, which determine the price difference. In addition to the above-mentioned high performance, some high-end laminate flooring also has color and surface treatment, such as synchronized grain, hand-scratch grain, Pearl surfaces, mirror highlights and artistic treatments will also cause price differences.
2) Multi-layer solid wood composite flooring
The environmental performance of multi-layer solid wood is similar to that of laminate flooring. It is of the same grade in Europe. The difference is that it feels more like solid wood flooring. However, because it is made of plywood and veneer, the environmental protection is more difficult to control. As for the service life, in all flooring varieties Among them, it is the shortest, some even less than 1 year, and it all depends on the surface paint. Once the paint is damaged, you just dismantle the floor and repair it. There are multi-layer solid wood with a surface layer of about 2mm on the market. It is claimed that It can be polished N times, but since it is peeling or planing the surface, it will easily crack once polished, so give up this idea. The price of multi-layer solid wood composites is generally between 100 and 130 yuan, and there may be cheaper ones. Imported multi-layer solid wood is slightly more expensive. Most products are from Japan. Japan's resources are too poor and its environmental protection concept is relatively good. The surface of the floor is all 0.6mm, and labor is expensive in Japan, so the price of the floor is naturally higher.

Longzheng Impregnated paper laminated wooden flooring, commonly known as laminate flooring, is made of one or more layers of special paper impregnated with thermosetting amino resin and laid on the surface of artificial board substrates such as particleboard, medium density fiberboard, high density fiberboard, etc., with balance paper on the back and balance paper on the front. The floor is made of wear-resistant paper and hot-pressed.
