"National Mahogany Standard" defines mahogany as "heartwood of Pterocarpus, Dalbergia, Diospyros, Clematis, and Helix." "White skin" is the white part of the wood. The jargon of the mahogany world is also called "white edge", and its scientific name is "sapwood". From the cross section of the wood, the dark part in the middle is called "heartwood", and the whitish part around the heartwood is called "white skin". White bark is the part that delivers nutrients for trees. Compared with heartwood, it has a lower density and lower stress resistance. It is rich in nutrients and easily rotted by insects. If the surface and main structure of the furniture have white skin, they will be eaten by insects in a few years. This will not only affect the beauty of mahogany furniture, but also affect the firmness and service life of the furniture. The furniture revealed in CCTV's "Weekly Quality Report" survey found two or three pieces of white skin less than seven or eight pieces on the lower panel. The largest piece of white skin actually accounts for more than 60% of the entire part. What's more, the red rosewood furniture produced by some manufacturers not only hides a lot of white skin in the interior and concealment, but also exposes the white skin on the surface. Even important parts such as the table legs and the main structure have been incorporated. "White skin". Moreover, in addition to furniture made of mid-range mahogany such as red rosewood with white skin, some mahogany furniture made of precious mahogany such as large leaf red sandalwood, small leaf red sandalwood and Huanghuali also have white skin. In order to cover up the "defects", many businesses cover the specific material of the wood by gluing and painting, and color the white skin. Reason for fraud "White leather" furniture costs can be saved by 50% According to the Fujian Provincial Standards for Classical Craft Furniture of Fujian Provincial Quality Supervision Bureau (DB35 / T 741-2007), white borders are allowed to be used in mahogany furniture, but "products should have no sapwood on the outside, internal structural strength and sapwood, The area content of the sapwood on the part should not exceed one tenth of the part (excluding sapwood with a width less than 5mm). " At the same time, when selling such products, companies must inform consumers of the added parts. However, in order to reduce costs, some mahogany furniture manufacturers in Fujian Xianyou, such as Wanlin Classical Furniture Factory and Gongpinxuan Classical Furniture Co., Ltd., still add white skin to the mahogany furniture. In this regard, the sales staff revealed that compared to the high value of mahogany raw materials, Baipi is very worthless. At present, one ton of red rosewood in the wood market is generally forty or fifty thousand dollars, while a ton of white leather is only seven or eight hundred dollars, and the price difference is 50 to 60 times. Mixing white leather in furniture will reduce production costs. For the production enterprise, it is assumed that 10,000 cubic meters are processed every year, and each cubic meter is calculated as 10,000 yuan. If white skin is added, the output rate can be increased by about 3%. Save 3 million yuan in cost. According to the survey, adulteration with white skin is a well-known secret in the industry. According to industry insiders, the mixed technology of red and white is now quite high. When I saw the mahogany furniture, I couldn't tell which one was the white leather with the background color. It is difficult for ordinary consumers to find the greasy eyes even if they are smart eyes. Discriminate Four tricks to distinguish whether the mahogany has white skin In a responsible attitude to consumers, Liantianhong Furniture has been committed to exposing the abuse of white leather and furniture lacquer in the mahogany furniture industry. The person in charge of Yuexing International Home Liantianhong Furniture Store said that if you want to distinguish whether mahogany furniture is mixed with white skin, you can use the following four methods: first look at the color of the furniture. Black, white skin color is very light. Then, it can be distinguished by appearance and pattern. The appearance of mahogany is not very regular, mostly with twists and uneven thickness, and the pattern is mostly black ring. If it is a precious mahogany, it is generally impossible to use dark red and other dark bases for processing. Usually, after careful finishing and polishing, it is directly painted with raw lacquer to fully reveal the pattern. If the color of the finished product is black or there is no pattern, it can generally be determined as non-mahogany wood or mixed with white skin. Consumers can observe and distinguish under strong light. Third, you can ask the store to bring sandpaper to remove the lacquer of the mahogany furniture. When a nude mahogany furniture is displayed, you can see if it is adulterated. The last method is to ask an expert for guidance when buying. White skin is generally in more hidden places such as corners, and it is difficult for ordinary consumers to perceive it with the naked eye, so when purchasing, you may wish to invite experts with certain practical experience, even if it is painted, it can still be seen. In addition, consumers should pay attention to the labels and product manuals when purchasing mahogany furniture to understand the basic raw materials, quality compliance, hazardous substance content, and maintenance of the products. It is best to ask the dealer for relevant documents such as timber import documents to verify the identity of the timber. Before the formal purchase, a third-party authoritative testing agency may be entrusted for identification or a distributor shall be required to issue a test report from the third-party authoritative testing agency.
