Nitrogen generation by Pressure Swing Adsorption (PSA) process is a technology used to separate nitrogen from a mixture of gases under pressure according to the special selective adsorption characteristics of the Carbon Molecular Sieves (CMS).
The Carbon Molecular Sieve is a material containing tiny pores of a precise and uniform size that is used as an adsorbent for gases. When the pressure is high enough, the oxygen molecules, which pass through the pores of CMS much faster than the nitrogen molecules, are adsorbed, while the coming out nitrogen molecules will be enriched in gas phase. The enriched oxygen air, adsorbed by the CMS, will be released by reducing the pressure. Then the CMS is regenerated and ready for another cycle of producing nitrogen enriched air.

However, for the Da Vinci statement, many netizens pointed out that the question is not whether the furniture is made in China, but whether it is real or not, whether there is fraudulent consumer behavior. The reporter yesterday followed the city's industrial and commercial bureau to his Yan'an West Road store and Qingpu warehouse survey, found that Da Vinci's furniture materials are either not marked, or the words "Italian original product quality", "Italian raw materials" and other vague words. The relevant person in charge of the Municipal Administration for Industry and Commerce said that some of the products sold by Da Vinci may be suspected of falsifying the origin and quality of the products. At present, the industrial and commercial department has investigated the case. First check Yan'an West Road store:
"The boss is abroad", refused to interview at 10 o'clock yesterday morning, the reporter followed the law enforcement officers of the Municipal Industry and Commerce Bureau to arrive at the store where Finch Furniture is located at No. 433 Yan'an West Road, the city. In the store, more than 400,000 yuan of bed, more than 100,000 yuan of sofas, TV cabinets, bedside tables abound.
The relevant person in charge of the Inspection and Quarantine Bureau of the Municipal Administration for Industry and Commerce said that the industrial and commercial department will conduct a comprehensive inspection of the products of the Cappuccino products exposed by the media. The specific inspection contents include the promotion of the products, the label, and the explanation of the salesmen to the consumers. Finch furniture does exist to claim to consumers that the product of Cappuccino is solid wood, but it is actually made of non-solid wood materials. It will be punished according to Article 49 of the Consumer Protection Law. Regarding whether it is "national export to domestic sales", the person in charge said that the industrial and commercial department will contact the customs and other departments to verify the relevant procedures for the import declaration of the products of the Cabernet.
The store clerk refused to interview on the grounds that "the boss is still abroad", "the manager is busy", and said "I don't know" about other issues. Qingpu warehouse sampling:
130,000 bedside table non-solid wood
Around 12 o'clock, the law enforcement officers of the Municipal Administration for Industry and Commerce and the relevant inspection department experts arrived at the Qingpu warehouse site of Finch's home. 233 pieces of Cappuccino furniture were sealed up the day before, mainly related to the bedstead of the bedroom and the tables and chairs of the restaurant.
“I know that all the furniture in the warehouse is imported.†Xu Weifeng, the warehouse supervisor, said that he has been working at Da Vinci for 11 years, and all the furniture of Da Vinci will be delivered directly to the warehouse. It is then sent to Da Vinci's national stores, with an average daily shipment of about 4 trucks. “There is no furniture shipped from other parts of the country. All the furniture in the warehouse has customs declarations.†Xu Weifeng once again stressed.
On-site law enforcement officers opened a Cabri furniture packaging box with a bedside table inside, with an original price of more than 130,000. The English part of the two product manuals of the cabinet is: "100% Italian original product quality", "all made in Italy", "using Italian raw materials and natural high-quality raw materials", "according to typical Italian crafts and traditions" Made, but does not clearly indicate what the specific natural ingredients are. The experts of the National Construction Engineering Materials Quality Supervision and Inspection Center, Lou Minggang and Zhang Zhiyu, “opened the belly†to the bedside table. “This bedside table is mainly composed of a variety of non-solid materials.†Zhang Zhiyu gave preliminary test results: the desktop is a MDF, and the external sticker Melamine paper; drawer panel is resin material, drawer side panel is multi-layer board (or plywood), and drawer bottom board is particle board with melamine paper. According to the relevant regulations of the state, when the furniture is sold, it must be clearly stated that the main material is made of solid wood or wood-based panels. If the solid wood is also marked with tree species, etc., the specific identification must be checked for the sale of the store.
The bill of lading shows that "on June 27, 2 pieces of this type of bedside table were sent from the warehouse to Yan'an West Road, the city." Check the Yan'an West Road store again:
Bedside table signage is blank
At 14:30, the industrial and commercial law enforcement officers returned to the Finch Yanan West Road store again. There are no signs in front of the two identical bedside tables in the Cabernet show area on the first floor. When the reporter asked the materials and prices of the bedside cabinets of the two salesmen, the answer was actually "We are new, don't know", said to ask the front desk staff, the front desk staff said to find sales staff.
It was not until half an hour later that a staff member took a stack of placards and picked two of them and dropped them. The signs show that the two bedside tables are CF/30-CH002-101, the original price is 132,600 yuan, the current price is 92,820 yuan, the origin is Italy, but the main material is blank.
In this regard, Zheng Hong, deputy director of the Fair Trade Department of the Municipal Administration for Industry and Commerce, said that the main materials used in the sale of furniture are unclear or missing, and the industrial and commercial department will require rectification. Some products sold by Da Vinci may be suspected of falsifying the origin and quality of the products. At present, the industrial and commercial department has filed a case for it, and is conducting on-site inspection of the products. It is found that some products have quality defects, such as the name of the product, the site, The industrial and commercial departments will further investigate the sales situation of the entire company, such as the origin of the logo is not standardized, the main materials are missing, or only rough information such as wood or skin.
Customers come to the door to ask for return consumers: 200,000 pieces of furniture are sitting without a break. Sales staff: It will inevitably have quality problems after 5 years. After the media exposed Da Vinci furniture quality problems, it has aroused the concern of many consumers. Yesterday afternoon, a number of customers came to the Da Vinci store on Yan'an West Road, asking the store to give a statement on the quality of the product and submit a return.
Because of the media reports, the public 缪Fushou was suffering in the store. It turned out that two years ago, he spent 2 million yuan to buy furniture in Da Vinci. I didn't expect to have problems after buying it for more than a year, but it has been dragged on for more than a year before and after, and still has not solved the problem. Mr. Wang complained that the bed he bought in Da Vinci, the bed board was quickly broken, and the sofa cloth was cracked. "The furniture of 200,000 yuan is broken without sitting!" For these problems The staff in the store explained that the products purchased in 2006, nowadays, will inevitably have quality problems. “Is it possible to use tens of thousands or even hundreds of thousands of dollars of furniture for five years?†Consumers do not agree with this explanation.
130,000 yuan bedside table non-solid wood business case to Da Vinci "lie detection"
After CCTV exposed Da Vinci furniture raw materials and origin fraud, yesterday, Pan Zhuang Xiuhua, general manager of Da Vinci Home Co., Ltd. still insisted that the agent's brand furniture was “100% original imported†when interviewed by CCTV. The company even issued a statement saying: "Da Vinci's Italian-branded furniture sold in China is produced in Italy and imported into China." Da Vinci plans to hold a press conference on Wednesday, and does not answer the media's other problem.
