First, the thickness is divided into thin and thick (8 mm and 12 mm).
In terms of environmental protection, the thin ones are better than the thick ones. Because of thin, the amount of glue used per unit area is relatively small. Thick, the density is not as high as the thin, the impact resistance is almost the same, but the feet feel a little better. In fact, there is little difference between them. In fact, there is no difference between the two kinds of floor thickness and quality. The key is to see individual choice.
Two. There are standard, wide and narrow plates from the specifications.
The standard width is generally 191-195 millimeters. The length is about 1200 and about 1300. The width of the board is more than more than 1200 millimeters, and the width is about 295 millimeters. The length of the narrow plate is 900-1000 millimeters, and the width is about 100 millimeters. The specifications of near wood floors are mostly imitation solid wood flooring.
The standard specification is adopted by most members of the European floor Producers Association. That's still the case. China's import of the world's most advanced and enhanced flooring processing line is also the use of standard specifications. That is to say, the use of imported pipeline processing, large-scale production enterprises of reinforced flooring products, the vast majority is still standard specifications. There are many distributors on the market, boasting that their products are imported, often said: "Imported does not have a wide board specifications and thickness of about 12 mm size." It should be the vast majority of imported flooring, no width board size and thickness.
The wide board specification is invented by China's flooring processing enterprises to meet consumer demand. Its advantages are looked at generously, and the floor gap is relatively small. Most of them are thickened, which is about 12 millimeters. Generally, the decorative paper on the surface is made in China, and the colors are varied and flexible. The disadvantage is that the chromatic aberration is relatively large, and the UV resistance of decorative paper is almost the same.
Narrow plate specifications are also characteristic of our country. Solid wood flooring look generous, too expensive, poor stability; China's floor manufacturers made imitation of solid wood flooring, looking at its specifications and solid wood flooring, cheap price, stability and good, four sides made of V-shaped groove, really can be fake, the thickness is basically about 12 mm. Less than a year has been popular in the market.
Three, from the surface coating of three oxidation of two aluminum, melamine, piano lacquer.
The standard strengthened floor surface should contain three oxidation two aluminum wear-resistant paper. It has 46 grams, 38 grams, 33 grams, and lower, directly spraying three oxidation two aluminum on decorative paper. The state stipulates that the surface wear-resistant revolution of the interior laminated floor should be more than 6000 revolutions. Only 46 grams of wear-resistant paper can be used for the floor to meet the requirements. The wear resistance of 38 grams of wear-resistant paper can reach 4000-5000 revolutions and 33 grams lower. The direct spraying of three oxidized two aluminum can achieve 2000-3000 turns. Low wear-resistant revolution, material cost is relatively low; because of its low wear-resistant degree, cutting tool cost is also low. On the contrary, the higher the wear resistance is, the higher the cost is.
Melamine surface coating, generally used in wallboard, desktop board, etc., used in places with low wear resistance requirements. In the flooring industry, this kind of surface coating floor is called "false floor". Its wear-resistant revolution is only 300-500 revolutions, if the use of high strength, the surface of decorative paper after two or three months will wear. Standard reinforcement floors will not have such problems in normal use for 10 years. This kind of floor decorative paper has no wear-resisting layer on it, the pattern is good-looking and clear, and it is smoother to touch with hands. This is where the layman is easy to fall for.
The surface coating of the piano lacquer is actually used for painting the surface of the solid wood flooring to strengthen the floor. The brighter paint is used. The wear resistance of the coating is far from that of the three oxidized two aluminum surface. It has low wear resistance, and solid wood flooring is developing towards high wear resistance. Unless you like this kind of surface coating.
Fourth, from the floor characteristics are divided into crystal, relief, lock, silent, waterproof and so on.
The crystal surface is basically flat. Good care. Clean up.
From the front, the relief face is no different from the crystal face. From the side, the relief face is hand-touched and has a wooden pattern on the surface.
Lock the joint of the floor, the use of lock form, that is, to control the vertical displacement of the floor, and control the horizontal displacement of the floor; the original mortise and groove type, that is, often said the floor, can only control the vertical displacement of the floor. No matter how early the wooden floor block is, there is no mortise and groove at the joints, and the displacement can not be controlled in any way. Therefore, the floor block often heaves up and trips when walking.
Mute, that is, add cork pads on the back of the floor or other cushions similar to softwood. After using the cork mat, the noise of treading on the floor can be reduced by more than 20 decibels (quoted from the cork mat factory data), and the effect of foot sensation, sound absorption and sound insulation can be increased. This will play a positive role in improving the comfort of reinforced flooring. It is also a direction for future development of reinforced flooring.
Waterproof, in the entrance of the strengthened floor, coated with waterproof resin or other waterproof materials, so that moisture outside the floor is not easy to intrude, the internal formaldehyde is not easy to release, making the floor of environmental protection, service life has been significantly improved; especially in large areas, inconvenient to leave expansion joints, compression strip Under the condition, the floor can be prevented from arch and the floor contraction joint can be reduced.
To sum up, the relief is really good-looking; if you use the same gram of wear-resistant paper, the crystal wear resistance than the relief is relatively high; mute feet really good, is expensive; waterproof, cost-effective
