In the impression of ordinary people, mahogany furniture is expensive, uses æ¦«å¯ structure, and belongs to environmentally friendly furniture. However, in the process of processing, the use of unqualified materials or processes are not standardized, and there may be problems of non-environmental protection. According to experts, in order to ensure the environmental protection of mahogany furniture, it can be supervised in a customized way to ensure the environmental protection and reliability of mahogany furniture.
Non-environmental auxiliary materials or cause pollution
Recently, Mr. Zhang consulted: In a certain mahogany furniture brand to buy furniture, the shopping guide said that the surface treatment of mahogany furniture is a large paint or hot wax process, there is no environmental problem. While visiting the factory, the workers were seen to paint the same material directly on the furniture, which had a distinct paint smell. Mr. Zhang is very puzzled. Is mahogany furniture really environmentally friendly and pollution-free?
Different from ordinary solid wood furniture or panel furniture, mahogany furniture adopts æ¦«å¯ structure, uses less glue, and does not have excessive formaldehyde. Under normal circumstances, mahogany furniture is environmentally friendly and reliable. However, according to industry insiders, the use of non-environmental materials in the lacquering or hot waxing of mahogany furniture may also lead to environmental protection.
According to Sun Shudong, director of the Furniture Inspection Laboratory of the National Furniture and Indoor Environmental Quality Supervision and Inspection Center, there have been cases in the furniture inspection laboratory that require the environmental protection of mahogany furniture. Mahogany furniture belongs to solid wood furniture. The method of testing is generally to sample proportionally, that is, to cut some samples from the furniture, and put the sample into standard air for extraction and analysis. Sun Shudong said that the current testing project for furniture is mainly formaldehyde. From the current test results, there are no unqualified cases; however, there are no test cases for the paint or paraffin used in mahogany furniture.
“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 when testing finished furniture.†Sun Shudong pointed out that harmful substances such as heavy metals may remain on furniture. After all, there are fewer furniture inspection items, and there is no specific method for testing furniture accessories. If it is not environmentally friendly, the harm is inevitable.
Low cost of environmentally friendly materials
According to reports, in the production process of mahogany furniture, multiple links and chemical accessories have "intimate contact." First, mahogany furniture is divided into two types: glue and glue. "Glue" furniture uses glue and other materials to make up for loose joints caused by imperfect structure. Some manufacturers use glue in the concrete structure. If you use urea-formaldehyde glue that releases a large amount of formaldehyde, increase it. Secondly, mahogany furniture in the surface treatment process, generally have two processes of painting or waxing, if the manufacturer uses inferior industrial paint or industrial paraffin, it may lead to environmental protection.
According to Zhang Zhengji, chairman of Mingjia Hongmu, the large paint process used since the Ming Dynasty is very different from the current industrial paint. He said: "The large lacquer process uses natural tree lacquer cut from trees. This material is extracted from the trees. After more than 20 water grinding processes, it is completely polished. It is completely different from the current industrial lacquer. According to reports, this "great paint" process is to paint the furniture with tree varnish, carefully polish the paint, so that the paint is soaked into the interior of the furniture. After the paint is dried, paint and polish it again. After repeated dozens of times to ensure the paint and wood. Melt into one. The waxing process covers the surface of the furniture after the wax has melted. The material used for the waxing is generally a mixed wax made of beeswax or beeswax, paraffin, rosin, or the like.
The materials used in the large paint process or the hot wax process are different in quality and value, and the value is also different ten times. It is understood that the market price of tree paint is hundreds of yuan per kilogram, while the inferior industrial paint is very cheap. Similarly, the price of ordinary paraffin and the price of natural beeswax are also very different. Sun Ying, general manager of Daqian Hongmu, also said: "The different brands of mahogany furniture on the market are almost identical in terms of materials and shapes, but the price is much worse. It is likely that the paints and other accessories used are different. Although the quality of the accessories is not visible, However, after using it for a long time, the poor auxiliary materials will appear to fall off and peel off, and the harm to the human body is also inevitable. It is recommended that consumers should carefully inquire about the materials used in the purchase, and if necessary, carry out tests to avoid unfriendly materials. hurt."
Industry voice: no absolutely environmentally friendly mahogany furniture
Hu Desheng, classical furniture expert
There has been debate in the industry about whether mahogany furniture is suitable for waxing or painting. At present, there are few completely natural excipients, no matter the paint or wax, and there are fewer brands that follow the classical skills. After the large-scale industrial production of mahogany furniture, many manufacturers aim at profitability, and do not pay attention to the quality of furniture. There is no absolutely environmentally friendly furniture. At the time of purchase, the macroscopic observation is 5 meters away, the modeling style is seen outside 3 meters, and the material texture is observed within 1 meter.
Large paint process for more expensive furniture
Zhu Dengfeng, General Manager of Mingjia Rosewood Club
Da Lac Craft is a classic of Su Zuo Craft. There are not many brands currently used in the market, and many consumers do not understand it. This kind of process is more suitable for high-grade furniture such as red sandalwood and huanghuali, because the large paint process itself is expensive and expensive, and it has high added value in the furniture with higher value.
Consumer reminder: industrial paint is easy to produce patent leather
Compared with natural tree paint, ordinary industrial paint is easy to produce patent leather after being applied to the furniture surface. If the surface of the furniture is hit, it is prone to peeling and falling off, and the surface of the natural tree paint is coated with uneven pits. When the consumer purchases, he can carefully observe the details of the parts that are easy to impact and determine the material of the paint used in the furniture.
Supervise polishing waxing program
Inferior paints often have a pungent smell when applied. Some unscrupulous merchants will apply a layer of tree paint on the inferior paint surface to cover up the smell in order to save costs. Consumers can choose the way to customize the furniture, observe the production process regularly, and supervise the materials and processes in the later stages of production. You can also negotiate with the manufacturer to visit the polishing wax and other processes to ensure that the materials used are authentic and environmentally friendly.
Abnormal light should pay attention
Compared with paraffin wax, beeswax contains more impurities and no industrial paraffin is smooth and transparent. Mahogany furniture needs regular waxing and maintenance. If the furniture is very bright after waxing, but the duration is short and the wear is serious, it is possible to use paraffin. Similarly, consumers can observe the use of excipients and processes to avoid furniture contamination by customizing or visiting the production process.
