How is the multi layer hardwood floor made?

There are two types of common parquet, three-layer hardwood flooring and multi-layer hardwood flooring. The three-layer solid wood floor was produced earlier, and it is composed of three layers of wood boards, including the surface board, the core board and the back board. The surface layer is a high-quality hardwood specification slatted paneling or a whole wooden plank, and the wood species are mostly oak, beech, birch, ash, etc.; The core layer is composed of ordinary soft miscellaneous wood slats, and the bottom layer is rotary cut veneer, and the wood species are mostly poplar, birch, and pine.

The three-layer structure is laminated with glue, and the multi-layer parquet is laminated with multi-layer plywood as the substrate and the specification hardwood sheet panels or veneer as the panels. Multi-layer hardwood flooring consists of seven or nine layers, and the stability is better than that of three-layer hardwood flooring. Especially in the geothermal environment, multi-layer solid wood flooring is highly heat-resistant and less prone to deformation.

Therefore, when purchasing, you should find out whether to buy three-layer or multi-layer parquet according to your own needs. If you're choosing a floor for geothermal heating, be sure to choose a multi-layered one. Structurally speaking, when consumers buy, they can see the structure of the veneer layer by layer through the four-sided tenon of the multi-layer solid wood floor.

Traditional multi-layer solid wood flooring substrates are made of odd-numbered layers, usually seven or nine layers. In recent years, some brands have improved the traditional process by adopting an even number of layers, i.e. eight or ten layers. Consumers may wish to pick up the floor when purchasing, look at the structural layer of the floor, and count how many layers it is.

Multi-layer solid wood flooring is a high-grade flooring material, which is made of multiple layers of wood bonded, which has good wear resistance and aesthetics. The following points need to be paid attention to when laying multi-layer hardwood flooring:

1.Ground preparation.

Before laying a multi-layer hardwood floor, it is first necessary to prepare the floor for carrying. Clean the floor and check that the floor is flat, if there are unevenness, it needs to be sanded and repaired to ensure that the floor is flat.

2.Measurement and layout.

After the ground is ready, measurements and layouts need to be made. The first step is to determine the starting point and orientation of the multi-layer hardwood flooring, and in general, it is best to lay the floor vertically on the longest wall. Then, according to the results of the measurement, the drawings and design schemes are listed to decide how the floor will be laid.

3.Install the flooring.

Before installing multi-layer hardwood flooring, it is necessary to prepare the necessary tools and materials. For installation, the floor is first laid on the ground for matching, and then cut. Glue the tenons and place the floor according to the measured floor.

Press the floor with a heavy object, wait for the glue to dry, remove the heavy object, and the floor can be firmly attached.

4.Cutting and splicing.

The laying of multi-layer hardwood flooring requires cutting and splicing. When drainage pipes or other infrastructure need to be laid on the ground, a chainsaw or hand saw is used to cut and splic, and tenons and nails are used to secure the multi-layer hardwood floor.

5.Grinding and sensitive cleaning.

After the laying of the multi-layer hardwood floor, it needs to be sanded and cleaned. Use sandpaper to sand the floor to remove roughness and unevenness from the surface. The floor is then cleaned with a floor cleaner to ensure that the floor is clean and tidy.

The main bridge is chaotic, and laying multi-layer solid wood flooring requires attention to detail, patience and technical level. If you don't have relevant experience, it's best to ask some professional laying company to do the laying. A well-laid multi-layer hardwood floor can last for a long time, while also increasing the aesthetics and value of the house.

<> laminate flooring is generally composed of four layers of materials, namely the wear-resistant layer, the decorative layer, the base material and the bottom layer.

The bottom layer of laminate flooring is a moisture-proof layer, which is generally made of polyester material, which can block moisture and moisture from the ground, so as to protect the floor from the moisture of the ground, and play a balancing role with the above layers.

The substrate layer is the main part of laminate flooring. Most laminate flooring is based on high-density fiberboard. Because MDF has many advantages that raw wood does not have, MDF has a uniform structure.

1. Uniform particle distribution, etc. The quality of MDF is mainly distinguished by its density value. Above the substrate layer is the decorative layer, that is, the pattern layer, which is made of a specially processed paper material.

The general process is, after soaking the special paper with a certain pattern into the ammonia solution, after chemical treatment, the chemical properties are stable after the heating reaction of the ammonia hydrochloride, and the characteristics of chemical reaction no longer occur, so that this paper becomes a beautiful and durable surface paper, the surface paper itself has a wear resistance of 40 0 revolutions, and waterproof, ultraviolet protection and does not fade.

The so-called wear-resistant layer is a layer of wear-resistant agent that is evenly pressed on the surface of the laminate floor. This abrasion resistant agent is formed by evenly distributing aluminum oxide in a thin film, which has very good wear resistance. The intrinsic factors that affect the wear resistance are mainly the content of aluminum oxide and the thickness of the surface film.

In today's market, the wear resistance layer of laminate flooring is mainly divided into four grades, the wear resistance of the floor containing about 3 0g of aluminum oxide per square meter should be about 40 0 0 revolutions, the wear resistance of the floor should be about 3 8g should be 50 0 0 revolutions, the wear resistance of the floor of about 44g should be about 90 0 0 revolutions, and the wear resistance of the floor of about 62g can reach about 1 80 0 0 revolutions.

Basically, laminate flooring is composed of the above four layers, which forms the wear resistance, moisture resistance, relative stability and beauty comparable to solid wood flooring. Solid wood multi-layer flooring, which is made of solid wood throughout, is different from laminate flooring with high-density fiberboard as the core material. Generally speaking, the solid wood multi-layer floor is composed of about 5 layers of solid wood, and the wood texture of each layer is vertically crossed with the adjacent two layers of wood, which can eliminate the stress inside the wood, and basically eliminate the shortcomings of the floor that it is easy to warp and crack.

Solid wood multi-layer flooring, most of the use of a variety of precious natural wood as the surface layer, and the use of advanced technology to squeeze the wear-resistant polyurethane paint into the wood gap, and then cured, so that the paint and wood into one.

Solid wood multi-layer flooring not only has the advantages of natural solid wood natural beauty and comfortable feet, insect resistance, moisture resistance, etc., but also has the characteristics of laminate flooring that is not easy to deform and easy to install, which is very popular and has good market prospects.

Solid wood multi-layer flooring was good.

Solid wood multi-layer floor is made of a lot of laminates overlapping and staggered by applying resin glue for high pressure and high temperature, this solid wood floor has a good ability to adjust the indoor temperature, it is more stable than ordinary wood boards, not easy to be subjected to thermal expansion and cold contraction, the dry shrinkage rate is small, and it is not easy to crack and deform.

Solid wood multi-layer flooring is much better than solid wood single-layer flooring, and it is an improvement on the use of single-layer solid wood flooring. The use of its substrate is mainly plywood, the general surface layer is precious wood species, and the surface has undergone a series of mosaic panels and planing to form thin wood, and its decorative effect is very obvious, which is a kind of high-quality floor of great practical significance.

The production process of solid wood multi-layer flooring

1. Only good wood can produce a good floor, and the impact of log quality on floor quality is very important. The quality control of a good brand starts from the selection of logs, and good wood is the basis for producing high-quality flooring.

2. The process of log rotary cutting and drying is used to process and make solid wood core board of solid wood multi-layer floor substrate, and the quality of the base material solid wood core board is inseparable from the quality of the finished floor.

3. The solid wood core board is sorted to ensure the quality of each piece of flooring, and the regular manufacturers usually only select the uniform thickness and moderate thickness, and the floor substrate is selected by full-time sorters.

4. The professional gluing equipment for the core board gluing and plastering can ensure the uniform amount of gluing and improve the efficiency of gluing. The 8 10 layers of glued thin solid wood core boards are arranged in an orderly criss-cross and layered manner, and glued together, which can change the original stretch direction of the wood fibers.

Solid wood multi-layer floor is a new type of floor between solid wood floor and laminate flooring, which not only has the natural texture and elasticity of solid wood flooring, but also overcomes the common problem that natural solid wood flooring is easy to expand and shrink. Let's take a look!

Is solid wood multi-layer flooring good

Pros:

1. Affordable

Since it is not made entirely of logs, it saves a lot of money compared to solid wood.

2. Good stability

It is produced by the process of horizontal and vertical intersection together, so the stability is excellent, there is no need to worry too much about the phenomenon of deformation due to moisture, and the solid wood multi-layer floor is also the first choice for installing floor heating in the home.

3. Easy to take care of

Because its appearance is painted, it is very wear-resistant, and it does not need to spend too much time or money to maintain in the later stage, and the solid wood multi-layer floor on the general market can be unwaxed within 3 years, and it can also maintain the brilliance of the paint as new.

4. Cost-effective

Its raw materials are added to a large number of logs, so the feeling of bare feet is very comfortable, not much different from solid wood, in addition to its aesthetics is also very high, the appearance is made of high-grade wood, which looks the same as solid wood flooring, but it is much cheaper than solid wood flooring, so we can think that it is very cost-effective.

5. Simple installation

Its installation does not need to adopt keel, only requires the flatness of the surface layer of the foundation, can do the basic leveling work, and has little influence on the floor height, generally 100 square meters of room can be paved in one day.

Cons:

There are advantages must also have its defects, compared with solid wood, the biggest deficiency is environmental protection, the production of unavoidable use of glue, so environmental protection can not be guaranteed to a certain extent. In addition, due to the high process requirements and complex structure, the quality of multi-layer flooring of various manufacturers is uneven, so we try to consider big brands when choosing.

Tips for choosing solid wood multi-layer flooring

1. Check the structure

First of all, observe the structure of its products, it is generally around the tenon, because the naked eye can see the veneer layer by layer, the previous such floor substrate mostly uses odd layers, so you can observe it well when purchasing.

2. Paint quality

In the era of paying attention to health, environmental protection is of course important, so it is necessary to consult what kind of glue the manufacturer uses, whether it can be written into the contract, and if there is a problem, you can also find the merchant for compensation. In addition, the quality of the paint on the surface of the floor is also very important, so it is necessary to consult the paint to find out whether the paint is an environmentally friendly coating, and it should not contain halogenated hydrocarbons, heavy metals, formaldehyde and other harmful radioactives.

3. Splicing process

Here can be observed with the naked eye, take out about 5 pieces of the model from the box and put it on the ground to assemble it, and pat it tightly on the tongue and groove, and then observe whether the tenon groove is tightly combined, touch it with your hands, feel whether it is flat, if the tongue and groove are not strong, and the touch is not smooth, it is recommended that such a multi-layer solid wood floor is best not to buy.
