>>>Industry revealed that counterfeit wood floor fake screen The national standard for solid wood flooring is GB/T15306-2001. The standard was implemented on May 1, 2002, and the original 94 standard was replaced at the same time. The new national standard has made important changes and additions to the old national standard. Mainly to modify the content of some dimensions and defects, supplement the specifications of the applicable tree species and the requirements for the paint board. At the same time, the requirements on the impact toughness and wear resistance of wood have been eliminated. Solid wood flooring is divided into three grades: AA grade, A grade, and B grade, and AA grade has the highest quality. Because the use of solid wood flooring is relatively delicate, installation is also more complicated, especially after moisture, exposure to deformation, so choose solid wood flooring to pay more attention to the quality of wood and installation process. How to buy solid wood flooring? Most of the quality problems of wooden floors are due to improper decoration. There are two types of wood flooring: surface lacquer and plain lacquer. The lacquer flooring can be laid on the cracks. After the primed board is laid, it needs to be planed and polished, then the transparent putty is scraped twice and the paint is applied twice. How to clean and maintain the solid wood floor <br> After the solid wood floor is laid, it can be used after at least 24 hours of health, otherwise it will affect the use of solid wood flooring. General solid wood flooring poor water resistance, should not use wet cloth or water to wipe, so as not to lose luster. In the following daily life, solid wood flooring must be maintained.

Strong acid and alkali liquids clean wooden floors. Floor purchase floor acceptance paint door price furniture window room decoration style glass furniture glass door craft glass

Solid wood flooring is divided into two types according to the depth of surface processing. One is the paint board, that is, the surface of the wooden floor has been painted, and can be used directly after installation; the other is the board, that is, the surface of the wooden floor is not painted, and must be polished and painted after laying. Can use it.
The types and price positioning of solid wood flooring are divided into the following categories: rosewood, clouded wood, teak, etc. The most expensive, cherry wood, beech, maple, etc., followed by ash, beech wood and Southeast Asian miscellaneous wood.
Solid wood flooring has three grades: AA grade, A grade, and B grade. The AA grade has the highest quality and the least color difference. When testing solid wood flooring, visual defects such as dead knots, insect eyes, oil eyes, tree cores, etc. shall be visually observed. The number of joints shall be less than 3, the depth and length of the crack shall not be greater than 1/5 of the thickness and length, and the slope of the diagonal lines shall be less than 10%. No corrosion point, graphic texture straight.
Solid wood floors should be further tested for their processing quality: Substrate defect values ​​require straight edges, no burrs, cracks, wormholes, etc.; surface paint quality, requiring the surface paint lacquer, no blisters, folds and so on. Specific selection of available caliper measurement in the middle and both sides are the same, and then use 5-8 block floor together, to see whether the joint after the joint, flush, with or without height difference and length difference. The moisture content is the most critical indicator and it is required to be between 8-13%. Excessively high and low moisture content can cause warping or cracking due to environmental changes after paving the wooden floor. The floor water content in the northern area should be less than 10%, and Wuhan should be around 12%, otherwise it should not be used.
In the purchase of solid wood flooring, should be based on their own actual situation to be determined. First of all, the wood species of the selected solid wood flooring should be determined in accordance with the requirements of the design style, such as the darkness and lightness of the color, the sparseness and denseness of the wood grain, and then be positioned on the basis of their own economic ability. After confirming the above requirements, we should carefully examine the square standard and notch splicing standard of wooden floor: Match two solid wood floor slots to slide, check whether the sliding is smooth, and whether the joint between the board and the board is smooth.
In the choice of solid wood flooring, do not be good or bad on the color difference. Solid wood flooring is a natural material, even if it is a tree on the wood, its sun-facing and shady face is also a color. Chromatic aberration is an inevitable factor of natural materials, it does not affect the quality of the floor, nor does it necessarily affect the appearance.
In addition, the length and width of solid wood floors should not be considered when selecting products. The long board has high requirements for material selection and large loss, so the price is high. In the construction process, it is not very easy to deform. The small plate material has high utilization rate, low price, and is not easily deformed and is economically applicable.
In everyday use, care should be taken to avoid scratching the floor with hard objects such as heavy metal sharps, glass tiles, and spikes; do not pull on the floor surface when moving furniture; do not expose the floor to open flames or place high-power electrics directly on the floor. Devices; strong acidic and alkaline substances are forbidden on the floor; long-term flooding is strictly prohibited.
If the outdoor humidity is greater than the indoor humidity, you can close the doors and windows to keep the indoor humidity low. If the outdoor humidity is less than the indoor humidity, you can open the doors and windows to reduce the indoor humidity. When it is hot and humid, you can drive in an air conditioner or an electric fan.
The humidity in the room should not be too large. Keep the floor dry, smooth and clean. Use a wrung cotton mop to clean it everyday. In case of stubborn stains, wipe with a neutral cleaning solvent and wipe it with a wrung cotton mop. Never use it. Wash with an organic solvent such as an acid, a basic solvent, or gasoline.
In order to maintain the aesthetic appearance of the floor and extend the life of the paint. It is recommended to wax twice a year for maintenance. Wipe the floor clean before waxing, then smear a layer of floor wax evenly on the surface, dry it slightly and wipe it with a soft cloth until it is smooth and bright.
If large-scale flooding occurs or water is partially immersed in water for a long time, dry water should be promptly dried with a dry cloth and allowed to dry naturally. Drying with an electric heater or exposure to sunlight is strictly forbidden.
Exposure to strong sunlight for a long time, or sudden temperature fluctuations in the room, may cause premature aging of solid wood floor finishes and should be avoided as much as possible.
If the installation is complete, for example, it is temporarily not possible. To maintain the circulation of indoor air, do not cover it with plastic paper or newspapers, so as to avoid long-term surface film stickiness and loss of luster.
Clean the floor regularly, vacuuming, and prevent sand or frictional dust from accumulating to scratch the floor surface. A doormat may be placed outside the door to prevent sand or frictional dust from being carried into the room. Clean the floor with a dry cotton mop. Do not wipe the floor with a wet mop or a corrosive liquid such as soapy water or petrol.
In order to increase indoor air humidity in autumn and winter seasons, humidifiers can be used to keep indoor air humidity between 50% and 70%. When moving furniture, it should not be pushed or pulled directly on the floor. It should be lifted and moved gently. Furniture that moves frequently can have a rubber on the bottom.
