The key raw materials of SPC floor are PVC and lime powder. PVC is a non-toxic renewable energy for environmental protection at room temperature. Lime powder is natural stone indoor formaldehyde,Although there are millions of wood species, there are not many suitable wood for flooring.According to GB / t national standard for solid wood flooring, the national standard for solid wood flooring in China is coniferous wood with air dry density not less than .g/cm and broad-leaved wood with air dry density not less than .g/cm The main applicable wood species under this standard are oak (oak)(there are different opinions about oak. The store will say the same. On the Internet, some say oak, some say oak, but some say oak), birch, two winged bean, muscarine, round bean, teak, elm, ash (Fraxinus mandshurica), iron sapphire, etc. if it exceeds this range, it should be carefully considered otherwise the quality is not good or the price is unbearable.Lacquer cloth green ( piece)Boma, If the outdoor humidity exceeds the indoor humidity, close the windows and doors to maintain a low humidity in the room. If the outdoor humidity is lower than the indoor humidity, open the windows and doors to reduce the indoor humidity.In case of cold and humid temperature, central air conditioning or electric fan can be used.We can also scrape the board with a blade.The real solid wood floor is painted with wood, and the refurbished board is made of floor, white putty and paint.Scrape the surface with a blade. If it is white, it is a refurbished plate.How to choose the floor?What is the difference between solid wood, composite and reinforced? Ultra light and ultra-thin, SPC floor has a thickness of about mm-mm and light weight, which is less than % of ordinary ground materials. It has incomparable advantages in stair bearing and space saving in high-rise buildings. At the same time, it has special advantages in the reconstruction of old buildings.
It is roughly divided into common solid wood flooring, reinforced composite wood flooring, solid wood composite flooring, bamboo flooring, high corrosion-resistant flooring, plastic flooring, antistatic flooring and outdoor stalls according to raw materials.According to the level of ecological environment protection,GuanajieHow about laminate flooring, it is divided into European standard E and E floor, Japanese standard - F star floor regulated by JAS star, etc.E, which is often referred to by Chinese manufacturers, is the name of Chinese specifications, but there is no name of E in European standards.It is simple to clean, bright as new, dirt free and easy to clean. The surface of solid wood reinforced composite floor is painted and treated very well, with good wear resistance,For laminate flooring, the main standard of floor environmental protection is formaldehyde emission.In terms of the limitation of formaldehyde emission standards, E and FCF.At an earlier stage, the formaldehyde emission standard of wood-based panel is E level (formaldehyde emission ≤ mg / g), and its formaldehyde emission limit is very loose. Even for products meeting this standard, the formaldehyde content may exceed more than three times that of E level wood-based panel, seriously endangering human health, so it must not be used for home decoration.Therefore, there was the first environmental protection revolution. In this environmental protection revolution the flooring industry implemented the E level environmental protection standard, that is, the formaldehyde emission is ≤ ? / L. although it basically does not pose a threat to the human body, there are still a lot of free formaldehyde left in the floor.The flooring industry has started the second environmental protection revolution and launched E environmental protection standard, which has reduced the formaldehyde emission of the floor to . ? / L.The best way to identify whether the floor is environmentally friendly is to pry the floor from the lock with a screwdriver and hammer, so that the floor substrate is exposed in a large area, and then smell it with your nose. A good floor should have a wood smell, but a bad one has a strong pungent smell!Foot feel SPC floor adopts marble powder and new materials, and it can be flame retardant. It has no affinity with water and is not easy to mildew. Stone plastic floor has sound-absorbing effect, so we don&#;t have to worry about the sound of high-heeled shoes hitting the ground anymore.
The cross section of the floor is rubbed with a file so that the heat generated in the cross section is the full volatilization of formaldehyde (formaldehyde will accelerate the release above ℃, and some irritating smell can be smelled). At this time, you can smell it. Generally you can smell three different levels of smell:Inspection requirements,Eighth, bright as new, dirt free and easy to clean. The surface of solid wood reinforced composite floor is painted and treated very well, with good wear resistance and does not need to spend a lot of energy on maintenance. It is reported that good solid wood composite floor in the market can keep the paint bright as new without waxing within years. This is in sharp contrast to the shape and maintenance of wood floor.The wooden floor packaging produced by reliable manufacturers should have the manufacturer&#;s name, detailed address, operation manual and national standards marked in Chinese.Since , the national standard for lifting wood flooring has been gradually implemented, and its name and serial number are the national standard: GB / t- prepreg paper laminated wood flooring.Guanajie,If the new floor is to be sent to a room equipped with large equipment, it may need to be rewired before moving.Make sure to contact an electrician before installing the floor.If the equipment needs to be moved, there is no need to worry that the heavy machinery will scratch it before installing the old floor.Keep tarpaulin and tape.Applicable part editing voiceSome customers want to take a lighter to light the SPC floor to see if it can burn. If it burns, it is not fire safety, and if it doesn&#;t burn, it is flame retardant.In fact, the national regulations on the flame retardant grade of PVC latch floor meet the B Standard, and the flame retardant raw materials are listed as class a fire safety according to the national standard, such as marble, wall tiles, etc.The technology of Class B flame retardant grade includes mm diameter cotton wool, sprinkled with ethanol,GuanajieComposite laminate floor, and placed on the PVC latch floor for natural ignition. After the cotton wool is burned, accurately measure the diameter of the burned PVC latch floor impression. If it is less than mm, it is Class B flame retardant grade.Instead of watching it burn.
