Weekly Quality Report: Uncovering the Dark Screen of Green Decoration Materials Not long ago, Mr. Ding in Chaoyang District of Beijing bought several blockboards to renovate his new house. He hadn’t had to wait until he moved in to live.
Mr. Ding: I feel that there is a particularly dazzling odor in this room. My eyes are open and tears are flowing. Sometimes I can't stay at all for a long time and I can't breathe easily.
The reporter found that there was a pungent pungent odor in the room. Mr. Ding told us that he had looked for vendors for this, and the seller said that it was a normal smell of wood.
Mr. Ding said that this kind of blockboard was bought from the Beijing Dianban particleboard market.
At a booth in the Denko particleboard market, we found a vendor.
Weekly Quality Report: Uncovering all sorts of shady reporters on green decoration materials: What is this smell?
Boss: The smell of wood itself.
Reporter: What is the smell of wood itself?
Boss: Right.
The boss told us that there is no problem with the quality of this blockboard, and many decoration companies have purchased it here. How can the original smell of wood be pungent? The boss disclosed that the blockboard was produced by Xingtai Xinyuan Wood Company of Hebei Province and the reporter decided to go to Xingtai City for investigation.
Weekly quality report: Uncovering the dark curtains of green decoration materials According to the address provided by the dealer, the reporter found the plate factory in Zhucun Town, Xingtai City.
In the office, we met the owner of the board factory. The reporter noted that the owner’s business card is marked by Lin Xing Wood Industry Co., Ltd., not Xinyuan Wood Industry Company.
Reporter: Your factory is Xingtai Linxing Wood Industry Co., Ltd. How is the product target site "Xinyuan Wood Company"?
Boss: In general, this brand is no one to control, what kind of brand customers want to play what kind of brand.
The reporter noticed that there was a pungent pungent odor in the yard. This is the smell we smelled at Mr. Ding’s home.

This odor is floating out of the workshop. In the production workshop, the reporter saw that the workers were busy trying to piece together the wood. This kind of wood strip does not have a pungent pungent smell, but a strange phenomenon caught the attention of reporters. Workers put a small plate around the iron billet and placed a large number of small wooden strips in the middle.
Reporter: Are you different from the ones you put outside?
Worker: This is a package. It looks good outside. People also wear broken clothes inside to make them visible, and people who wear them can see.
The reporter learned from the workers here that piles of small wooden sticks are in the yard. The reporter found that these small wooden sticks are easily broken.
Weekly Quality Report: Uncovering the Shady Green Decoration Materials (2)
Reporter: Is it broken?
Boss: We are specializing in this kind of thing and specialize in leftovers.
The boss told us that these small wooden sticks are used scraps and are used to process blockboards. There is a lot of space in the blockboard that is scraped together with scraps of wood.
Reporter: Is there a gap?
Worker: It will be able to put it away.
Reporter: It will be able to be put away for a while.
It turned out that the way the worker handled the gap was to fill the gap with a large amount of sawdust. Put together a layer of veneer after putting together the wood and filling the sawdust. The reporter noticed that the veneer was very sticky and gave off a pungent smell.
Reporter: This taste is very strong, it seems that the smell of spicy eyes on the board?
Worker: Tea taste.
Worker: Tea taste.
Weekly Quality Report: Uncovering the Shady Green Decoration Materials (2)
Reporter: Tea taste, how can tea taste pungent and harsh?
Workers: I can't feel it.
The pieces that were put together were sent into the machine for drying and molding. After high-temperature treatment, the odor emitted from the veneers was more pungent. A worker told us the truth.
Worker: This smells hot eyes.
Reporter: Why is it so hot?
Worker: Why is it so hot-eyed?
Reporter: What is this thing? What is this?
Worker: Glue.
Weekly Quality Report: Uncovering the Shady Green Decoration Materials (3)
The blockboard was made of scraps from wooden strips, small slats and sawdust, and a large amount of glue was rolled on the slats during production. The worker responsible for the roll-over tells us that the glue is very toxic and the eyes are particularly uncomfortable when working in the factory for a long time.
Reporter: I see your eyes are swollen?
Worker: spicy.
Why is there such a pungent pungent odor in glue? Workers told us that the glue was provided by a local glue factory. According to clues provided by the workers, the reporter found the glue factory in the local area. There are more than a dozen plastic barrels in the yard. This two-story hut is a vinyl workshop. Workers are busy gluing.
Reporter: What are you putting on?
Worker: Urea.
A pipe connected to the large tank outside the yard caught the attention of reporters. Following this water pipe, the reporter found a wagon loaded with several vats.
Reporter: What is pumping up?
Weekly Quality Report: Uncovering the Shady Green Decoration Materials (3)
Worker: Formaldehyde.
Formaldehyde has a strong irritant effect on the human body's mucous membranes, especially the respiratory system, and it poses a great danger to human health. Therefore, the state has strictly stipulated the formaldehyde emission limits in blockboards. During the investigation, the reporter learned that the plastics they produced were called urea-formaldehyde glue, and the production of 1 ton of urea-formaldehyde glue used 600 kg of formaldehyde. The spicy, pungent odor in the blockboard is the smell of formaldehyde.
Reporter: How do you wipe your eyes?
Worker: This spicy eye.
Reporter: Spicy eyes?
Worker: Right.
Reporter: The smell of spicy eyes on the board is this smell.
Weekly Quality Report: Uncovering the Shady Green Decoration Materials (3)
Worker: It is this smell.
Reporter: What is the smell of workers: formaldehyde.
The reporter then investigated the five rubber factories in Zhucun Town and Dongwang Town and found that the urea-formaldehyde glues used in these glue factories also use formaldehyde as the main raw material. The boss told us that the use of this urea-formaldehyde glue to produce blockboard formaldehyde emission limits are exceeded.
Reporter: What kind of factory is this glue sold to?
Boss: Local board factory.
Reporter: Is it a blockboard factory?
Workers: Joiners, particle board, what kind of board are all, and the template and wood-based panels use this glue.
Reporter: Formaldehyde (release limit) can meet national standards?
Workers: reach farts and fail to meet national standards.
Reporter: Can't reach the factory to use?
Workers: Who cares?
Weekly Quality Report: Uncovering the Shady Green Decoration Materials (4)
When the reporter returned to the Linxing plate factory again, the boss finally admitted that the pungent odor in the blockboard was the excessive release of formaldehyde.
Boss: This glue is smashed with formaldehyde and urea. The glue that meets the standard is not so hot or sloppy. It is safe for humans. Don't say 27 bucks for a board made with up to standard rubber. That means you cannot buy 47 bucks.
During the investigation, the reporter learned that because of the fear of inspection, they were all trademarks of printed plates at night.
Reporter: Where did the shipment go?
Boss: Go to Beijing.
Reporter: What market is being sent to Beijing?
Boss: Guanzhuang (chipboard) market.
Later, Xingtai reporter also interviewed wood companies such as Xingda, Jinpin and Shuangxiang. The owners of these plate mills all admitted that in order to reduce production costs, they all use urea-formaldehyde rubber to process blockboards.
Reporter: Did you all know that the rubber they sent was not qualified?
(Xingda) boss: Of course I know.
Reporter: Why do you know why?
Weekly Quality Report: Uncovering the Shady Green Decoration Materials (4)
(Xingda) boss: cheap, we are using this urea-formaldehyde glue.
Reporter: How much does a ton cost (compared with the glue that meets environmental standards)?
(Xingda) boss: 1,000 yuan.
Reporter: Do you have any inspection report?
(Blond) Boss: I can't leave this.
Reporter: The inspection report cannot be produced. Why?
(Blond) Boss: The amount of formaldehyde released is greater than the national standard.
Reporter: Are they over-standard?
(Blonde) Boss: Right.
(Shuangxiang) Boss: Who did not check the night inspection report.
Reporter: Why is it not? What glue do you use?
(Shuangxiang) Boss: The amount of formaldehyde released does not meet national standards.
In a further investigation, the reporter also found that the cabinets with excessive formaldehyde exceeded the “green†signboard and were sold to the building materials market in Beijing, Tianjin, Hebei, and Henan.
Reporter: I see you still playing "green" on this board?
(Shuangxiang) Boss: Formaldehyde emission is far from the national standard.
Reporter: How to say?
Boss: What brand does the customer want?
Reporter: Want to play "green" and hit "green"?
(Shuangxiang) Boss: What do the customers want?
Reporter: Where do you sell this board?
Boss: Beijing, Tianjin, and Zhengzhou all have.
Third, authoritative interviews:
Moderator: In the film just now we saw that the eyes of the workers who had been laundered were getting DC tears. Then what would the plates produced in this way bring to consumers? Mr. Lu Bin, deputy director of the National Panel Quality Inspection Center, came to our studio today.
Expert: Hello.
Moderator: In the past two days, we sent the investigated fine board to you for testing. Is there any result now? Can you tell us?
Weekly Quality Report: Uncovering the Shady Green Decoration Materials (4)
Experts: The results came out, and these samples failed to pass the comprehensive judgment. The result of this test of formaldehyde is also very rare, and it exceeds the national mandatory basic standards. For example, the level E2 of our joinery sheet is 5.0 milligrams per liter.
Moderator: How much is this super?
Expert: This time over 5 times.
Moderator: Many people know urea fertilizer, but also know that formaldehyde is harmful, why must use these two as the main raw material?
Experts: Now the world, including developed countries, have adopted this adhesive, this is a common resin.
Moderator: Since everyone uses these two kinds of materials as the main raw material, why is the formaldehyde of the companies we have just investigated seriously excessive?
Expert: This urea-formaldehyde resin is not for everyone to do. It is very difficult to do well. In the production process, there are strict process flow, strict formulation and production methods. For example, the amount of urea and formaldehyde, the proportion of the size, while adding these fixed amount on the basis of how much to add, is divided into several times, plus the time. If you follow this process, you can make a qualified adhesive, otherwise the adhesive will not meet the requirements.
Moderator: This blockboard has a five-story structure, and the center should be spliced ​​with natural wood strips, plus two affixed veneer, so it is also called Daxinban. This kind of material is also used in many foreign countries. The processing of blockboards is very particular. Let's take a look at the normal processing methods.
The production of a blockboard generally takes more than 30 processes, of which the core processing is the most critical link, so the formal enterprise requirements for the core material is very strict. No insects, no mildew, 4 to 5 cm wide wood strips can become the core board splicing material. Moreover, because of the selection of wood strips, all of them have been subjected to a drying process. Therefore, the fine wood planks produced have a compact overall structure and are not easily deformed by long-term use.
The urea-formaldehyde glue is generally used for the splicing and bonding of qualified fine wood panels, but the formaldehyde content of the glue is in full compliance with national standards. Therefore, there is only a dry woody smell on the production site, and there is no smell of pungent formaldehyde. Because the low formaldehyde content is not conducive to the adhesion of the sheet, companies use large core bonding equipment to increase the adhesiveness of the sheet by gravity extrusion.
Moderator: At the beginning of the program, I mentioned that the State Administration for Industry and Commerce recently announced the results of random sampling of blockboards on the market. The sampling qualification rate was 32.2%. The main problem was excessive formaldehyde, and the AQSIQ also After three consecutive inspections of blockboard products, the product qualification rate has never exceeded 60%. The main problem is that formaldehyde is too high. Why is this old problem just like excessive formaldehyde?
Experts: Mainly at present some small-scale enterprises, its production facilities, production conditions, including the quality of production and technical personnel can not meet the requirements of the national standards, I think these are not in line with production conditions, do not have production conditions, no production facilities, lack of production The facilities of these enterprises, I think the relevant departments should be given supervision, if they do not meet these conditions, they should be prohibited from production.
Moderator: According to what exactly is the quality of fine wood panels? Formaldehyde is not excessive, these problems are very professional, only professional departments can accurately detect the detection, so that consumer identification is a little difficult for people, but know some simple identification method is better than know it, what are the methods? Take a look.
The fine wood board is commonly known as the Daixin board. Consumers should pay attention to the following aspects in the process of purchase: First, let's look at the flatness of the board. A good big board is relatively flat and relatively poor. The core board is warped. In addition, we can look at the other side of the board. This side is commonly known as the end of the board. We can see that the board has a relatively evenly arranged core board, generally about three finger widths. Bad Daxinban, its end is uneven on the one hand, and everyone can see (use) some very broken slats made of. After a good core board is put up at one corner, it is more resilient and flexible. The poor quality of the big core board, after picking up a corner, it made a buzzing sound.
Moderator: It is also a good idea to look at the test report of this plate. For example, when I go to buy this plate, I can ask the dealer to ask for a test report?
Expert: This test report is a measure of a company's ability to produce products that are not qualified. Enterprises that attach particular importance to the inspection of each batch of products must be tested and qualified before they can enter the market.
Moderator: In addition, after buying this material, in addition to leaving a good invoice, you can also saw a small piece of sheet as evidence.
Experts: Yes, this is very important, that is, after the completion of renovation found that there is a problem to stay a piece of plate, 500 * 500 mm board is well preserved, it is best to sign the two sides, we all agree, in case of problems, can be used as time The identification of indicators is good.
Moderator: Well, thank you for coming to our studio.
Last year, the China Indoor Decoration Association's Indoor Environmental Monitoring Center once conducted indoor air testing on 1,000 homes in Beijing. As a result, 60% of households have exceeded formaldehyde standards. What are the dangers of living in such an environment for a long time? How can we know if the formaldehyde in our home exceeds the standard? What do we hear from outside experts?
The director of Jin Yinlong, director of the Department of Environment and Health-related Product Safety at the Chinese Center for Disease Control and Prevention, harms people's health in many ways. First of all, it manifests itself in the effects on facial features and respiratory system. It can cause tears, throat discomfort, cough, and sneezing. And so on a series of respiratory symptoms, the second aspect, it can cause allergies people have some allergic reactions, feel itchy, there are some skin rash, the third aspect may cause some pregnant women's premature delivery and miscarriage, and It may cause nasal cancer and nasopharyngeal cancer, which the WHO has now confirmed, and of course there is still a lot of research to be done in this area.
Director of the China Indoor Decoration Association's Indoor Environment Monitoring Center Song Guangsheng recognizes that the method of exceeding the standard of formaldehyde depends on the fish raised by the family. If fish and flowers die easily, it is not easy to survive. This is also related to formaldehyde pollution.
The main symptom of the formaldehyde pollution reaction is the feeling of respiratory stimulation after opening the door, as well as hot eyes and tears in the eyes. This is a common reaction.
Moderator: In addition, if you feel that the air in your home is abnormal, you can also contact the following ways. There are also relevant departmental contacts in various places.
Reporter's investigation: The unveiling of the "green" decoration material host: Do not know if you have this feeling, standing in the newly renovated home, people seem to have become beautiful, and the posture after the decoration has become warm and stylish, but Sometimes people do not think that the air in the home has changed. Who doesn’t pay attention to the air quality we breathe at all times? Just recently, the State Administration for Industry and Commerce announced that the inspection results of fine wood products sold in the seven building materials markets in Beijing, Luoyang, and Zhengzhou showed that the pass rate was only 32.3%. Among the unqualified products, most of them were caused by hidden killer formaldehyde. Exceeded by the standard. Blockboard is a kind of plate that can pack door and window heating, but also can be made of furniture, etc. Who can not leave it decoration, then the formaldehyde in the blockboard is where it comes from? Why would it exceed the standard?
