Direct contact with formaldehyde can cause skin allergy, pigment spots and atrophy. Inhalation of high concentration formaldehyde can cause chronic bronchitis.The double composite solid wood floor adopts double-layer solid wood pressing. It feels like pure natural wood. The installation and maintenance is very simple. It is suitable for floor heating, beautiful and generous, good reliability, and contains a small amount of indoor formaldehyde.The joint of the floor adopts the form of latch, which controls the vertical displacement of the floor and the horizontal displacement of the floor;The original tenon and groove type, which is often called tongue and groove floor, can only control the vertical displacement of the floor.No matter how early the wooden floor plate is, there is no tenon and groove at the joint, and the displacement in any aspect can not be controlled. Therefore, which is inconvenient.Quality inspection report,First, look at environmental protectionThe first kind: pungent taste. If the floor tastes like this,OrimattilaManufacturer of SPC flooring,OrimattilaFloor skirting, break the floor and look at the substrate inside. There are no impurities in the good substrate and the color is relatively pure. A large number of impurities can be seen with the naked eye in the poor floor substrate.Most domestic floors use fast-growing forests, and wood has been used since to years. However, imported floors, especially FSC certified plates, have strict restrictions on wood species, so wood base materials are better.
Needless to say, for a long time, the lacquered cloth market was occupied by low-grade unlined lacquered cloth produced in Taiwan and other overseas countries, giving consumers the wrong message that Chinas quality is not up to standard. In fact, after the inspection of these, the surface wear-resistant layer is only .mm, which is made of poorly processed and Recycled PVC. It does not meet the national standards for plastic coiled materials at all, so its service life is short, not comfortable to use.where, See: whether the thickness of the ground lacquer cloth is full, printing layer and wear-resistant layer of the bottom layer are layered, whether there is the bottom layer, whether the thickness of the bottom layer is like a cicada wing, and whether the back of the ground lacquer cloth is black.Two winged beans: thick and expensive.Generally, the moisture content of non dry wooden keel is about % and that of qualified wooden floor is generally about %. If the humidity difference is too large, the wooden floor is easy to absorb moisture quickly. If the time is long, the floor will arch up and the paint will crack.Therefore, it is best to choose dry and straight wood as keel.After the keel level is determined, the keel and floor can be fixed with nails.Orimattila,The general specification and model of general floor is cm×cm the specification and model of high-capacity floor can reach cm×cm, with a total area of times that of the general wooden floor.The floor is generally made of common materials such as red sandalwood and Huanghua pear wood. The corner material is discarded and made of a key part of the whole tree. It mainly shows the air. The road construction has an endless sense of flexion and extension and three-dimensional feeling. Wear resistance, wear resistance Grade TIs the home floor paved with solid wood or structurally reinforced floor?
