Many consumers do not have excessive inspection and acceptance after the renovation of the home, which leads to these problems in the daily use of building materials in the home. Today, Jiuzheng Building Materials Network brings consumers the method of self-detection of wooden floor quality. Have you seen whether the quality of your own wooden flooring has passed?
First, the symptoms of poor quality wood flooring
1, the floor surface is not flat (should be ≤ 2mm / m)
Reasons for the uneven surface of the floor: the ground strength is not good, sinking, the keel is not flattened, the keel is not nailed or fixed, the inferior man-made board is covered with large sheets, the floor is not properly maintained, and the foam mats overlap.
2, tile shape (should be ≤0.3mm/m)
Reasons for the formation of floor tiles: the keel is not dry, the wool floor is not dry, the back groove of the floor is too shallow, the board surface is too wide, it is laid with water-containing glue, arching, floor blisters, the floor is too dry, the moisture content is too low, the laying is too tight There is no expansion joint on the side.
3, the floor gap is too large (should ≤ 2mm) The floor moisture content is higher than the local equilibrium moisture content
The reason why the floor gap is too large is that the floor is too wide, the laying is too tight, the floor is processed with large and small heads, the laying is too loose, the floor is applied with adhesive in the gutter, and the shrinkage is concentrated.
4, rebound foot feeling too soft keel spacing is too large (should ≤ 35mm)
The floor rebound is too soft. The reason is: the floor is not flat, there is a gap under the floor; the keel is not fixed, there is a gap; the floor is not fixed on the keel; the floor long filling joint is not fixed on the keel; the sound is loud; the floor has no glue The nail is fixed on the keel; the floor is finished, no maintenance, and it is used immediately; the keel is not fixed.
Second, the quality of the floor is good or bad
Lee: Environmentally friendly, good thermal insulation
Wood is natural, and its annual rings and textures can often form a beautiful picture, giving people a feeling of returning to nature and returning to nature. No matter the texture is unique, it is widely loved by people. Wood is not easily conductive, and the thermal conductivity of concrete is very high. The thermal conductivity of steel is 200 times that of wood.
Lee: mitigate shock, wood can be regenerated
The impact and resistance of wood and human body are softer and more natural than other building materials, which is beneficial to the health of the human body and protects the safety of the elderly and children. Coal, oil, steel and wood are important resources for human beings, and some of them can be regenerated through planting. As long as the forest is well protected, it can be used inexhaustibly.
Disadvantages: difficult to maintain
Solid wood flooring has higher requirements for installation, which is equivalent to saying that from the beginning of installation, it takes a lot of effort to pay attention to the installation of solid wood flooring. After installation, due to the insufficient stability of the solid wood floor, the indoor environment is too humid or easy to arch, warp or deform when dry. After the paving is done, it is often waxed and oiled to maintain the floor regularly to achieve a strong gloss.
Disadvantages: high price
Due to various factors, solid wood flooring has been maintained at a relatively high price, and there is no possibility of downward adjustment in the short term. Now the market is slightly better, the price of solid wood flooring with better quality is also above 250 yuan / square meter.
