[ Chinese wardrobe network ] Recently, the author visited Tianjin home building materials market and found that many businesses are indeed selling so-called "E0" grade furniture.
In the basement of a furniture market, a brand of furniture sales staff said that the furniture such as sliding doors in the store are in line with the "European standard 'E0' class." That is to say, the amount of formaldehyde released per 100 grams of plate is ≤ 5 mg.
However, when the author proposed to look at the "E0" level inspection report, the sales staff could not get it.
The author then came to a furniture store on the 4th floor of the market. The sales staff said that the furniture in the store was in line with the “E0†standard. But she said, "E0" is the national standard and almost no formaldehyde.
During the conversation, she said that the “E0†class furniture is indeed more expensive than the “E1†class furniture. The same is the so-called "E0" level standard, but different business sayings are quite different, which can not help but make people full of doubts.
Quality inspection: Unqualified furniture is mostly due to excessive formaldehyde
According to the Tianjin Municipal Quality Supervision Bureau recently released the results of the regular supervision and inspection of Tianjin's product quality in the second quarter of this year, a total of 242 batches of products produced by 242 furniture manufacturers were sampled and 236 batches were qualified.
Among them, Tianjin Ruidong Weiye Furniture Co., Ltd., Tianjin Hongteng Office Furniture Co., Ltd., Tianjin Jinye Furniture Factory, Tianjin Kent Furniture Co., Ltd., Tianjin Guangda Home Decoration Co., Ltd. and other 6 companies produce 6 kinds of furniture. Due to the unqualified inspection items of drawer durability and formaldehyde emission, it was included in the quality “black listâ€.
According to China's formaldehyde formaldehyde content testing standards, the formaldehyde emission limit is not more than 1.5mg / L, but in this sampling, the Kent Furniture Co., Ltd. production date / batch of 2011-04 wooden cabinet as an example Its formaldehyde emission is 3.1mg/L, which is more than twice the standard.
According to estimates, in products that are not tested, formaldehyde exceeds 60%. The staff of the quality supervision department said that the main reason for the excessive formaldehyde was that the manufacturers used unqualified wood-based panels and inferior adhesives to reduce costs.
Ordinary wood-based panels have a phenomenon of sustained formaldehyde release. The fundamental reason is that the manufacturing process of the artificial board requires the use of an aldehyde adhesive such as urea-formaldehyde resin.
This adhesive is itself a direct compound of formaldehyde and urea. Because of its low price and good bonding effect, it is widely used in the manufacturing process of wood-based panels.
However, the biggest disadvantage of this kind of colloid is that it will spontaneously decompose and reduce under natural conditions, and release free formaldehyde again. And in a hot and humid environment, the reaction rate of this decomposition and deliquescence will double.
The essential difference between a good wood-based panel and a poor material is that eco-adhesive can be used instead of urea-formaldehyde resin. The safety and stability of the eco-gel can be free of formaldehyde and does not decompose free formaldehyde.
"E0 level" into a new selling point of furniture
It is understood that because the formaldehyde emission of furniture has become a hot spot for many consumers, some furniture brands have begun to launch "E0" grade furniture.
“Our furniture uses plates that meet the E0 environmental protection standards, so the formaldehyde emission is very low, absolutely environmentally friendly, and there is no pungent smell.†A salesperson of a brand furniture in Xinyang Furniture City said.
However, when the author asked if there was any quality certification passed by the relevant departments of the national quality inspection, the sales staff said that it was temporarily unavailable.
"Now no matter which furniture sales staff, they say that their products are environmentally friendly, even 'zero formaldehyde'." Mr. Ma, a citizen of Tianjin who is selecting furniture, said. Because the sales staff did not provide relevant credentials, as an ordinary consumer and lack of professional knowledge, these "environmental furniture" is difficult to distinguish between true and false.
Zero formaldehyde is actually just a "legend"
The staff of Tianjin Furniture Industry Association said that “E0â€, “E1†and “E2†refer to the environmental standards for formaldehyde emission limit.
According to the relevant regulations of the state, the formaldehyde emission of furniture can reach “E2†level before it can be sold. Due to factors such as manufacturing process, China basically does not really reach the “E0†grade furniture. The “E0†grade furniture sold in the Tianjin market is overstated.
Merchants play the "zero formaldehyde" slogan, which is to seize the consumer's attitude towards environmental protection, in order to increase its sales.
Professionals recommend that consumers buy furniture when they see whether they have passed the relevant certification, whether they meet the requirements of national environmental standards, and check the test report to see if the formaldehyde emission reaches the “E2†level.
Relevant experts also pointed out that the relevant decoration materials that do not contain formaldehyde so far do not exist. It can even be said that any kind of decoration materials have such harmful or toxic and radioactive substances. Even we think that the wood in the greenest forest contains formaldehyde. Can you say that there is zero formaldehyde?
So how do you control the various pollutions that occur during the renovation process?
It is mainly to use effective control means to make rational use of time and space so that they can be released and volatilized as soon as possible, so as to minimize the occurrence of low pollution and light damage, so as to finally meet environmental protection requirements.
In summary, there are only four types of wood flooring popular in the Tianjin market: solid wood flooring, laminate flooring, parquet flooring and bamboo flooring. No "zero formaldehyde" products exist in composite flooring or solid wood flooring.
Therefore, it can only be said that the formaldehyde content of some brand flooring is far lower than the national standard, and it is a green building material product.
Experts remind: "zero formaldehyde" requires national aldehyde-free test certificate
Although some of the plates themselves are made of natural fibers such as straw, there is really only a small amount of natural aldehydes in this natural fiber, and even the formaldehyde content of rice cannot be completely zero.
Therefore, wood-based panels produced from natural fibers are also more environmentally friendly and healthier than other panels.
Consumers can't be blindly pursued.
Silica gel relative to the ceramic tableware, plastic tableware, hardware, silica gel tableware harmony together with temperature, in which food is cold is hot, can protect the temperature of the food itself, reduce the loss of the change of temperature and a period of time in the silicone bowl or pot food can still maintain the original temperature, when use won't convey the temperature of the corresponding to the user. Moreover, the particularity of the silicone material itself, which is different from other materials, makes the products produced by it have an amazing effect. For example, landing silent food containers, after high temperature cooking, will not produce harmful substances. And tableware but fold, can knead, can turn over, chuai also does not take a space in the pocket, also won't adsorb smeary. Its own desiccant effect, will not because of long-term storage and moldy, qualitative change.
And because of silica gel temperature resistant properties, heat resistance of 240 ℃ high temperature deformation, won't produce hardening phenomenon to 40 ℃, so the product is fully staffed, very practical, we don't have to classification of casual in a microwave, don't worry about the melting and aging and yellowing phenomenon, and it is easy washing, can use less or even do not use detergent containing chemical substances, practicability and convenience are very strong, very suitable for use in their life.
