Testing PVC flooring

Firstly, how to use a simple method to detect the formaldehyde content of PVC floor to open the moisture-proof layer, expose the substrate, the nose smells irritating, and the formaldehyde content must exceed the standard. Formaldehyde is a colorless and easily soluble irritant, exceeding the national standard of 1.5mg / L (E1), mild throat discomfort, chest tightness, asthma, severe respiratory diseases or emphysema, pregnancy syndrome, nerves, Lung immunity is poisoned, especially for young children and the elderly.

Secondly, how to use a simple method to test the quality of the PVC floor substrate? The good substrate should be a high-density wooden fiberboard with a density between 0.83...0.95g/cm3 and good stability. The comparison with the naked eye should be pure color, moderate hardness, and no odor.

In addition, how to use a simple method to check the moisture resistance of the PVC floor? The good moisture-proof layer can prevent the floor from deforming and warping, and achieve good moisture-proof heat conduction and sound insulation. The naked eye observation should be fine workmanship, solid texture and pure color.

Identify PVC flooring

The first point is to first see if the PVC floor is sold in a specialty store.

Is there a power of attorney, whether there is an international quality certificate and a certificate of China's environmental labeling products, and an authority certificate issued by the state functional department; is there an inspection report (some commissioned inspection reports are not true, depending on the supervision inspection or daily inspection inspection report), Original. Since there is no, it may be a low quality PVC floor.

Point two, look at the information and album of PVC flooring.

Those words that are rough in printing, succinct in content, and that say that they are wearable and ruthless are misleading propaganda, which is caused by non-standard manufacturers.

The third point is to see if the manufacturer or the marketing organization has a standardized retail price, and whether it is a random price product. If this is the case, it is impossible to brand PVC flooring.

Point four, look at the PVC floor surface pattern.

Floors with blurred texture, unsatisfactory color, unnatural, and poor solid wood are not resistant to UV rays and are easily faded. These floors are undoubtedly low-quality PVC flooring.

Point five, look at the core material.

Those PVC materials with rough core core, dark color and easy to break corners, the formaldehyde content exceeds the national superior product standard, and the comprehensive floor index is mostly unqualified, which is a poor product.

Point six, look at the degree of PVC floor polishing.

Use woodworking sandpaper to apply force to polish the surface of the floor a few times. The low-quality counterfeit products have white marks and are lower than the national standard.

Point seven, look at the stitching effect.

Draw a pack of PVC flooring and stagger the three pieces. The problem of height difference and triangular seams as well as the edges are not straight, such a floor is a poor product.

Point eight, look at the bottom of the PVC floor.

Those colors are inconsistent, the texture is rough, there is no brand name, the deformation is large, the moisture is poor, and it is a low-grade product.

Point IX, look at the import board to see customs declarations and commodity inspection orders and certificates of origin.

The original imported floor has a place of origin, specifications, name, date on the list, and the relevant content of the Chinese translation on the package. More importantly, look at whether the number on the import list is tens of thousands of meters or more. Below tens of thousands of meters, it may have been imported a little original floor, but a large number of sold floors belong to the sheep head selling dog meat, which is self-produced or OEM. The product.

Point 10, look at the warranty card and sales receipt.

All formal PVC flooring manufacturers have official receipts, and the actual manufacturer's address and telephone number are on the package and product information. There is no real address and phone number on the inferior floor box and product information, or no address or phone at all.
