For a long time, when the citizens sent the questioned mahogany furniture to the quality inspection department for testing, they must face the sampling test. Regardless of whether there is any problem, the furniture has been “brokenâ€... Recently, the Guangxi Quality Supervision Department released the “Redwood Furniture and Productsâ€. Non-destructive testing test method (hereinafter referred to as "method"), the first to identify the identification method of non-destructive testing of mahogany, not only to maintain the appearance and structural integrity of the tested mahogany products, but also to restrict the Guangxi redwood market Filling up, making false acts, etc., to better protect and identify mahogany antique furniture and wooden artifacts. Recently, the mahogany “ID card†or water has been found in the market. Jiuzheng Building Materials Network has learned from many mahogany furniture stores in Nanning. In some big-brand stores, mahogany furniture is hung with “one card, one book, one cardâ€, but in some small and medium-sized brands or unbranded mahogany stores, “one card, one book, one card†is difficult to trace, some guides Indicates "not hanged out" or explicitly states "provided after sale". In the many mahogany shops in the Fu'an Judong store in Nanning, some of the so-called mahogany furniture are still placed on the price tag of ordinary goods. The reporter proposed to look at the material identification certificate. “We only have the certificate of the whole batch of wood, and there is no certificate for the individual furniture.†The shopping guide quickly said that the brand will write the relevant information on quality, materials and other information into the contract, and they will indicate “redwood type†and “false†in the signed contract. A penalty of ten." Compared to the obscurity of these mahogany shops, another mahogany shop guide is more "candid." "Do you want to buy or give away?" He suggested that if the reporter uses it himself, it is best to find someone who knows how to accompany him. If it is a gift, "we have any certificates, you can give the certificate issued by the factory, you can also give You have certified the organization's certificate and promised to have a face!" "Is your material identification certificate true? If it is another material, how can customers protect their rights?" When the reporter asked if the furniture was handmade, whether it could be quality tested or not. The salesperson's reply is very vague: "Redwood furniture is a penny of goods, you can choose according to the price." "Destructive" test is difficult. If the public has doubts about the purchase of redwood products, how to Identification? The reporter learned that at present, there are many institutions with qualifications for mahogany furniture inspection in Guangxi. After the inspection, the general conclusion can be drawn within 10 working days. The cost of testing a set of mahogany furniture is about 1,000 yuan. In the second half of last year, Mr. Chen, a citizen of Nanning, spent 40,000 yuan to buy a set of red rosewood palace chairs. After I was happy to buy it home, some friends and relatives questioned that the chair was "not like" red rosewood. He couldn't sit still now, and he was hesitant to make an identification. "I heard that the identification of mahogany is going to destructively sample the chair. This is my baby. I can't bear to make a decision." Because of the dilemma, Mr. Chen had to put the matter on hold. The reporter learned from the Guangxi Institute of Product Quality Supervision and Inspection, which has the qualification for mahogany furniture inspection, that for the samples of the mahogany submitted for inspection, a wooden sample with a diameter of about 8 mm and a height of about 5 mm is generally taken in the concealed part of the product. The quality inspection staff said that in order to avoid damage, the sampling site and sample size should be fully considered during sampling. It is impossible to sample on each furniture component, which is easy for the counterfeiters to take advantage of. In addition, the price of damaged mahogany products has also depreciated. Therefore, the identification of mahogany furniture is difficult to become a major problem for many consumers. Non-destructive identification can be accurate to the category. Can there be a way to accurately determine the type of redwood without destroying the appearance of the product? "Before we proposed the identification method of non-destructive testing of mahogany, there is no such standard in China, which makes all The wood identification agency has no basis for the identification method of wood identification.†On March 10th, the main drafters of the Method revealed that they directly took pictures of tree species on the surface of the mahogany products and compared them with the model specimens. To determine the tree species name or wood name. "At present, the common mahogany products on the market such as fragrant wood, rosewood, black rosewood, red rosewood, striped ebony, rosewood, chicken wing wood, etc. can be detected and identified according to new methods. He said that after the non-destructive identification method is used to detect the mahogany products, the inspection cycle and the process are greatly reduced because the samples of the mahogany products are not intercepted and the samples taken are sliced. He particularly reminded that there is a kind of fake leather mahogany furniture on the market, which is not suitable for non-destructive testing. Because the non-destructive testing and identification method only takes pictures of tree species on the surface of the mahogany product, it is suitable for the traditional wood tree species detection method. At the same time, the non-destructive testing method is applicable to mahogany products with smooth surface and no coloration, and is not suitable for mahogany products whose surface has been color-treated and rough.
