Laminate flooring laminate laminating technology, laminate flooring construction technology

What Brother Ren said above is the process of solid wood flooring! Here's what I learned from my first few months of internship at a floor decorating company! If there is a limited ability, try to put forward any mistakes Thank you 1, impregnated paper - 2, MDF HDF - 3, billet pressing - 4, trimming - 5, cooling - 6, single-piece sawing - 7, multi-piece sawing - 8, blank inspection - 9, aging storage - 10, milling - 11, finished product inspection - 12, finished product packaging, laminate flooring raw materials from top to bottom mainly include wear-resistant layer, decorative paper wear-resistant layer, base and balance layer.

Balance paper, decorative paper, abrasion resistant paper and substrate. The wear-resistant layer is a layer of wear-resistant agent evenly pressed on the surface of the laminate floor, which is formed by evenly distributing aluminum oxide in the film, which has good wear resistance and heat insulation and flame retardancy. The good balance layer has less harmful substance content, has good moisture-proof and flame retardant effect, good tensile resistance, can ensure the stability and perfection of the floor shape, and the corners of the floor are not easy to warp and wear.

MDF: Medium density fiberboard, the fiber structure of the board is uniform, the gluing strength between the fibers is high, so its static bending strength, plane tensile strength, elastic modulus, screw holding force and so on are better than particleboard. Low moisture absorption, water absorption, thickness expansion.

HDF: High-density fiberboard, high strength, good performance, durability, impact resistance. Ideal for use as a laminate flooring substrate.

Blank pressing: After the impregnated paper and high-density fiberboard are assembled, they are sent to a low-pressure short-cycle press for pressing. , trimming:

Trim the impregnated paper edge strips that are cured at the edges of the floor slabs. Cooling: Cooling the temperature of the floor slab.

Monolithic sawing: cutting the floor slab horizontally and cutting it in half. 、Multi-piece sawing:

The cut panel is cut longitudinally and cut into six floor blanks. Blank inspection: check the quality of floor blanks.

Aging storage: Through a long period of storage, the internal stress of the floor blank is released and the deformation of the finished floor is prevented. , milling:

Simultaneous milling of floor tongues and grooves with a double-end milling machine. Finished product inspection: check the quality of finished products.

Finished product packaging: Use heat shrink wrap flooring. Ensure that the floor is not damp before unpacking at the installation site.

1. Raw material procurement: directly imported from abroad suitable for making wood flooring and drying, sterilization, anti-corrosion treatment of wood floor blanks, these wood is generally characterized by wood hard, wear-resistant, corrosion-resistant, fresh and beautiful texture, good stability. Usually the tree is older, and the larger volume is preferred.

Before the raw materials enter the factory, they must be comprehensively tested and approved by the national wood inspection department for their materials, strength, hardness, tree species, etc.

2. After the wooden floor enters the factory, it needs to be sampled and inspected by the quality inspection department to ensure that the specifications, size, and appearance of the board meet the enterprise standards, and then neatly stacked in the warehouse after three months of aging treatment. The moisture content of the wooden floor is within 8-13% of the national regulations, and the effect of anti-corrosion and insect prevention is achieved.

3. Initial inspection and grading, removing waste materials, fine planing on the machine, grooves on both sides, and printing anti-counterfeiting marks. The process is produced by a full set of equipment imported from Germany, so that the geometric dimensions of the floor are accurate, the groove is standard, and the surface is smooth and clean.

4. Enter double-end milling, determine the length of the wooden floor, cut off the excess part, and groove at both ends.

5. Sanding on the sanding machine to make the wood floor reach a certain finish.

6. The planer-free floor is finished at the end of the processing process, and the packaging is plasticized and shipped out of the factory.

7. Paint-free flooring adds a painting process on the basis of planer-free flooring: this set of automatic painting line adopts a full set of equipment imported from Taiwan. Sand, vacuum, apply the first layer of colorless primer, and dry it with ultraviolet light; Then sanding, vacuuming, a second layer of colorless primer, and ultraviolet light drying; After that, sanding and vacuuming, the third layer of colorless primer is applied, dried by ultraviolet light, and finally sanded and vacuumed, and the natural color or color is applied to a roller and a two-layer coat, which is dried by ultraviolet light.

This concludes the paint-free flooring process.

8. The quality inspectors strictly follow the national standards to inspect the grade and color number of the wood floor, classify them, and finally seal the packaging and plastic packaging to leave the factory.

I am glad that the landlord has a problem, please forgive me if there is a mistake.

1. The pavement scheme should be constant.

For each stadium, or theater stage, what materials to pave, and how to pave, are determined according to the actual parameters of the sports venue and the investment budget. Therefore, once the sports wood floor paving scheme is decided, it should not be changed easily.

Frequent changes to the design and construction plan of sports wood flooring will cause additional investment and even affect the construction period. Therefore, in the design of sports wood floor paving scheme, it is necessary to communicate and coordinate with sports wood floor manufacturers, clarify standards, and avoid unnecessary problems.

2. Customized products should be in advance.

The overall structure of the sports wood floor is basically all solid wood structure, and the moisture content of the floor will be done according to the climatic conditions and moisture content changes of the installation project site during production, which is generally about 6%-14% on average. Before ordering sports wood flooring, it is important to allow sufficient time for production in order to ensure the quality of the flooring.

3. Avoid cross construction.

Cross construction, that is, the paving of sports wood floors, is carried out at the same time as other construction projects of stadiums and conflicts with each other. The sports wood floor paving project should avoid cross construction, so as to affect the smooth progress of the sports wood floor pavement, or the construction of other stadium construction projects destroys the paved sports wood floor floor.

4. Supervision and acceptance should be involved.

Although it is said that the installation project of sports wood flooring is operated by the pavement engineer of the sports wood floor manufacturer. However, the stadium contractor and Party A should also arrange a special person to be responsible for tracking and supervision, and solve the problems in the installation of sports wood flooring in a timely manner.

1. Prepare for installation on the ground.

If you want to install the sports wood floor, the ground must be flat and smooth, so the first step is to clean the sanitation of the ground, and also do a good job in the installation of indoor water and electricity equipment, so as not to let these equipment affect the installation and use of the sports floor.

2. Use professional tools.

All the professional tools used to install the flooring must be prepared. Once these requirements have been met, the next step is to lay the flooring. The installation of gymnasium wood flooring is a technical work, and it is necessary to invite professional installers from sports wood floor manufacturers to play a role.

3. Installation of wooden flooring in the gymnasium.

In order to make the floor last longer, the moisture-proof board should be laid first, the second layer is the rubber pad, and then the special sports floor should be installed above the bone line of 40mm. For each floor, use staggered sports floor nails to ensure that the floor is smooth and flat.

Laminate flooring is a commonly used flooring material in modern home decoration, which has many advantages such as anti-corrosion, waterproof, insect-proof, moisture-proof, and fireproof, so it is favored by consumers. However, in order to ensure the longevity and aesthetics of laminate flooring, proper paving methods are essential. The following is an introduction to the method of paving laminate flooring.

1.Ground treatment.

Check the floor for issues such as moisture, flatness, and cleanliness first. The ground humidity should not exceed 3%. If the ground is uneven, the Liangling should be leveled, and the flatness error should not exceed 3mm.

Before paving, attention should be paid to cleaning, removing soil, oil and dust, etc., to ensure that the ground is clean.

2.Paving the first floor.

Place the first floor in the corner of the floor or in the corner of the wall to ensure a neat and beautiful appearance. The first piece of floor should be installed close to the ground and beaten with a rubber mace until it is firm.

3.Floor splicing.

Laminate flooring should pay attention to the overlap position when splicing, and put one floor on another floor to make the splicing flat to avoid gaps. At the same time, it is also necessary to ensure that the level, flatness, verticality and compactness of each floor are consistent.

4.Short-circuit processing.

When splicing the floor, it is necessary to ensure that the surface of the floor is flat and the gap cannot be too large, otherwise it needs to be shorted, that is, the short strip is installed under the sheet iron at the floor splicing place to make the whole ground more solid and beautiful.

5.Corner processing.

Once the floor is spliced, the corners around the floor need to be treated. Generally speaking, decorative strips or trim strips are needed to make the floor more beautiful and also add a natural touch to the floor.

In short, when paving laminate flooring, it is important to pay attention to every detail to ensure that the pavement is neat and smooth, beautiful and durable. It's the devil in the details, and laminate flooring is no exception.

Laminate flooring is divided into four levels.

The first layer is a wear-resistant layer (transparent).

The second layer is the fancy layer (wood grain style).

The third layer is the base layer (MDF).

The fourth layer is the equilibrium layer (melamine).

Domestic laminate flooring basically has no wear-resistant layer, and a good wear-resistant layer not only has a protective effect, but also can prevent ultraviolet rays and prevent fading.

Each floor is marked E0 E1 E2 (formaldehyde release) E0 is the best standard for solid wood flooring, and it is also divided into solid wood and multi-layer solid wood.

Multi-layer solid wood is better than solid wood, not easy to bend and deform, there are almost no gaps, solid wood flooring will sound in summer due to wet expansion and contraction.

When laying solid wood floors, there should be a keel to fix the balance.

One press, two openings, three health, four slotting, five packaging, six factory.

At present, there are two kinds of laminate flooring construction technology:

1. Before laying laminate flooring, the ground is re-leveled with cement mortar, and then the floor is laid.

Second, before laying laminate flooring, first lay a thick floor mat, and then lay the floor.

Personally, I suggest that it is better to take the second construction method. The process is simple, the ground sound insulation effect is good, and the floor feels good.

First, installation tools and materials.

Tools to be used for installation: pliers, saws, drills, etc.

Small wooden blocks (about 1cm) of uniform thickness are separated by small wooden blocks in order to ensure that the gap between the floor and the wall is uniform and straight during installation.

The moisture-proof layer laid on the bottom layer has two functions, one is moisture-proof; The second is to make the feet feel more comfortable. Usually one layer is enough, and if there is more, the paved floor is like floating on the ground, and the fixation is not firm enough.

Second, drill the baseboard.

Before installing the floor, drill holes in the wall to prepare for the installation of the baseboard.

Key points: In order to ensure the firmness of the baseboard, the distance between each nail should not be too long, generally not more than half a meter.

1. Drilling.

2. Nail the wooden block into the drilled hole, and the nail that fixes the baseboard is nailed to this wooden block.

Third, lay a moisture-proof layer.

Before laying the moisture barrier, remember to clean the floor and make sure that the ground is dry.

Key points: Between the two moisture-proof layers, seal with tape to ensure the sealing effect.

Fourth, paving the floor.

Start laying the floor. Compared with solid wood flooring, the laying of laminate flooring is relatively simple, because it is a standardized product, there is no need to bother to pick up the color difference, because the quality is stable, and there is no need to consider the gap of the floor. Tiling and splicing the laminate flooring piece by piece is enough.

Fifth, there are two important points to pay attention to when laying.

1. Although the laminate floor is stable, there should still be a gap of about 1cm around it to prevent it from expanding due to moisture in the future. During installation, workers mostly use small wooden blocks (mentioned above) to fix them, install them and then take them out.

2. In order to ensure that the floor does not arch or deform in the future, the laminate floor should be separated by metal buckles at intervals. Generally, it is enough to use it at the interval in each room.

Sixth, install baseboards.

Fixed baseboards. The purpose of the baseboard is to cover the unsightly gap between the floor and the wall.

Key points: In order to achieve a harmonious decorative effect, the baseboard can be selected according to the color of the door cover or the color of the floor.

Seventh, wrap up the work.

The floors and baseboards were installed, but the whole installation was not completely over. Since the furniture did not come in when the floor was installed, the responsible construction team usually removed the packaging box and laid it on the installed floor to prevent wear and tear. In addition, don't forget to get the warranty card from the construction team to fill in the site after the construction team has installed it.
