There is no absolutely environmentally friendly mahogany furniture
In the impression of ordinary people, mahogany furniture is expensive and uses a tenon-and-mortise structure, which is environmentally friendly furniture. However, in the process of using unqualified materials or non-standard processes, environmental problems may also occur. Experts introduced that in order to ensure the environmental protection of mahogany furniture, it can be customized and monitored throughout the process to ensure that the mahogany furniture is environmentally friendly and reliable.   There is no absolutely environmentally friendly mahogany furniture  There has been debate in the industry as to whether mahogany furniture is suitable for waxing or painting. In the current market, no matter whether lacquer or wax is used, there are few completely natural accessories, and there are fewer brands that completely follow classical techniques. After the large-scale industrial production of mahogany furniture, many manufacturers aim at making profits, do not pay attention to the quality of furniture, and there is no absolutely environmentally friendly furniture. At the time of purchase, the macro observation is 5 meters away, the modeling style is 3 meters away, and the material decoration is observed within 1 meter.  Non-environmental auxiliary materials or cause pollution  Recently, when buying furniture from a mahogany furniture brand, the shopping guide said that the surface treatment of mahogany furniture uses a large paint or hot wax process, and there is no environmental problem. While visiting his factory, he saw workers apply the same substance as paint directly on the furniture, which has obvious paint smell. Is mahogany furniture really environmentally friendly and pollution-free?  According to Sun Shudong, director of the Furniture Inspection Laboratory of the National Furniture and Indoor Environmental Quality Supervision and Inspection Center, in the furniture inspection laboratory, there have been cases that require testing for environmental protection issues of mahogany furniture. Mahogany furniture is solid wood furniture. The method of detection is generally to sample according to the proportion, that is, to cut some samples from the furniture and put the samples into standard air for extraction and analysis. Sun Shudong said that the current testing items of furniture are mainly formaldehyde. Judging from the current testing results, there are no unqualified cases; but there are no testing cases for paint or paraffin used in mahogany furniture.  Mahogany furniture is different from ordinary solid wood furniture or panel furniture. It uses a tenon-and-mortise structure and uses less glue. There will be no formaldehyde exceeding the standard. Under normal circumstances, mahogany furniture is environmentally friendly and reliable. However, according to industry insiders, the use of non-environmental materials in the painting or waxing of mahogany furniture may also lead to non-environmental protection.  "Paint or paraffin contains harmful substances such as benzene and heavy metals. Benzene is volatile. When it is used as an auxiliary material in furniture production, it is difficult to detect it when testing finished furniture." Sun Shudong pointed out that harmful substances such as heavy metals may remain on the furniture. After all, there are few inspection items for finished furniture products, and there is no special inspection method for furniture accessories. If it is not environmentally friendly, harm will be inevitable.  Low cost of environmentally friendly materials  According to reports, in the production process of mahogany furniture products , many links have "intimate contact" with chemical accessories. First, mahogany furniture is divided into two types with and without glue. Some "glue" furniture uses glue and other materials to make up for the loose joints caused by the mortise and tenon structure. Some manufacturers use a lot of glue in the tenon structure. If you use urea-formaldehyde glue that releases a large amount of formaldehyde, increase it. The possibility of non-environmental protection; second, the surface treatment of mahogany furniture generally has two processes of painting or waxing. If manufacturers use inferior industrial paint or industrial paraffin, they may cause environmental protection.  According to Zhang Zhengji, chairman of the well-known Redwood, the large lacquer process used since the Ming Dynasty is very different from the current industrial lacquer. He said: "The big lacquer process uses natural lacquer cut from trees. This substance is extracted from the trees. After more than 20 water milling processes, it is completely polished, which is completely different from the current industrial lacquer. "According to reports, this" big paint "process is to paint the furniture with lacquer, and then carefully polish it to make the paint soak into the interior of the furniture. After the paint is dry, paint and polish it again. After more than ten times, the paint and wood are guaranteed. Melt into one. The hot waxing process covers the furniture surface after the wax is melted. The material used for hot waxing is generally beeswax or a mixed wax made of beeswax, paraffin, rosin, etc.  The quality of the materials used in the big paint process or the hot wax process are different, and the value is also different by more than ten times. It is understood that the market price of lacquer is hundreds of yuan per kilogram, while inferior industrial paint is very cheap. Similarly, the price of ordinary paraffin and natural beeswax are also very different. Sun Ying, general manager of Daqian Mahogany, also said: "Materials and shapes of different brands of mahogany furniture on the market are almost the same, but the price is much different. It is likely that the auxiliary materials such as paint used are different. Although the quality of the auxiliary materials cannot be seen, However, after using for a long time, the poor auxiliary materials will appear to fall off, peeling, etc., and the harm to the human body is also inevitable. It is recommended that consumers should carefully ask the materials of auxiliary materials when purchasing, and test if necessary to avoid being exposed to unfriendly materials. hurt."  Large paint process is suitable for more precious furniture  The big lacquer craft is a classic of the Su craftsmanship. At present, there are not many brands on the market, and many consumers do not understand it. This process is more suitable for high-grade furniture such as red sandalwood, Huanghuali, etc., because the big lacquer process itself is expensive in materials and labor, and has high added value in high-value furniture.
