With the concept of environmental protection continuing to deepen the hearts of people, many consumers began to pay attention to the concept of green environmental protection, so from the building materials, furniture, construction and even jewelry began to stir up a strong "green wind", environmental protection building materials also quickly occupied the entire building materials market. At the same time, some businesses have also grasped the psychology of consumers, and played an important role in environmental protection. It seems that as long as they are related to “greenâ€, they are all environmentally friendly products. But is this really the case?
â– Green core flooring does not mean that the environmental floor laminate flooring consists of the surface wear layer, decorative layer, wood base layer and moisture balance layer, and the most important is the wood base layer. From the outside, the base of the wooden floor is green. This is the so-called "green core" floor. In the interview, the reporter discovered that some businesses advertised their products to consumers as green products. The most important point was that the substrate was green and made of pure green wood, so it contained no added ingredients and Formaldehyde and other harmful substances. However, is the fact really like these merchants say? This reporter interviewed relevant experts.
Industry expert Zhao Zhigang pointed out that the country has a lot of hard indicators such as formaldehyde content for "green environmental protection" wood flooring. At the same time, there are specialized green product certification organizations, and only products certified by authoritative professional organizations can be called “green environmental protectionâ€. The "green core" is just a representation, it does not mean that it is a green product, but it does not mean that it does not contain free formaldehyde. Therefore, consumers should identify whether the product has an environmental certification mark.
According to the national standard GB18580-2001, laminate flooring tested by the desiccator method must meet the E1 standard, that is, formaldehyde emission should not exceed 1.5 mg/L. Only E1 certified laminate flooring is called green building materials. While some vendors deliberately confuse this concept, the wood floor substrate, which is usually made of high-quality wood, should be wood primary color. Some unscrupulous merchants use some mildewed wood as the substrate, intentionally adding green to the substrate in order to mask the color of the substrate. So for the "green core" floor, consumers must be careful to distinguish.
â– "Green core" is a moisture-proof floor-specific logo So, why is there a "green core" floor in the end? Experts gave such an explanation. In fact, the Green Core only adds green to the grassroots. The main purpose is to distinguish it from ordinary wood floors. Because the laminated wood laminate core is wood, it will be afraid of water. For this reason, there are many manufacturers of laminate wood flooring that add special moisture-proof additives to the process of producing high-density laminates, making the water-absorbent thickness expansion ratio of the flooring smaller than that of common cores and better moisture resistance than ordinary flooring. some. In order to distinguish this plate from ordinary plates, manufacturers often dye the moisture-proof core layer green, which is what the consumer sees as a green core floor. This practice first appeared in the foreign market. At the beginning, it was only the code of the company in order to distinguish different varieties, types of goods, and even sent it to various places. Later, it gradually developed into a specific logo for moisture-proof floors. However, on the market, there are some poor-quality, low-cost reinforced composite wood floors that have drilled this hole and the substrate layer has also been dyed green. However, in fact, no special moisture-proof additives have been added to the substrate. Instead, colorants have been added. , posing as moisture-proof board. Therefore, it is recommended that consumers must pay attention to checking the product's various index certificates at the time of purchase.
