"Zero Formaldehyde" has huge commercial value
Since formaldehyde is extremely harmful to the human body, it is also an unavoidable problem in the home improvement process, and has always been the focus of attention in household consumption. The generally accepted fact is that long-term inhalation of small amounts of formaldehyde can cause direct skin and respiratory diseases such as allergies and asthma, and may cause cancer, leading to serious diseases including leukemia, uremia, colon cancer, and brain cancer. For children, the elderly, and pregnant women, formaldehyde is particularly harmful.
Wood-based panel furniture is the main and long-term source of indoor formaldehyde. Almost all wood-based panels will release formaldehyde for a long time. This release will accompany the life of wood-based panel furniture. China divides man-made boards into E2 and E1 grades according to the amount of formaldehyde released. However, it is worth noting that our standard is very loose compared to European and American standards. Therefore, China's wood-based panel industry has also adopted the "E0 level" standard to distinguish some man-made panels with relatively small formaldehyde emissions.
However, regardless of whether the wood-based panel meets the E2, E1 or E0 standard, due to the continuous formaldehyde release, when the living room has a limited volume, a large decoration density, and limited ventilation conditions (especially the bedroom during sleep) There are different degrees of risk of formaldehyde exceeding the standard. A survey even claimed that about 80% of newly-installed families in China are facing excessive formaldehyde.
Under such circumstances, if "zero formaldehyde" household products really appear, it is undoubtedly a revolutionary solution to formaldehyde's health threat to the living environment. Its health value to the public and marketing value to the business will be huge.
"Zero Formaldehyde" plate, there is indeed
In this regard, we specifically investigated Wanhua Ecological Board Co., Ltd., which claimed to produce "non-formaldehyde-emitting" plates. The Hexiang board produced by this company is undoubtedly the largest and best selling "zero formaldehyde" board in the market. Several of the aforementioned major brands use this company's He Xiang board.
When asked whether it is really "zero formaldehyde" and how to achieve "zero formaldehyde". The person in charge of the company frankly explained the mechanism of "zero formaldehyde" of Hexiang board.
He explained that the fundamental reason for the continuous formaldehyde release of ordinary wood-based panels is that the manufacturing process of wood-based panels requires the use of aldehyde-based adhesives, such as urea-formaldehyde resins. 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. But the biggest shortcoming of this kind of colloid is that it will continue to decompose spontaneously under natural conditions and re-release free formaldehyde. And in a hot and humid environment, this decomposition and deliquescence reaction rate will double.
The fundamental difference between Wanhuahexiang board and ordinary man-made board is that MDI ecological glue is used instead of urea-formaldehyde resin. Due to the safety and stability of MDI, it does not contain formaldehyde, nor will it decompose to produce formaldehyde. This has created what the market calls "zero formaldehyde" plates.
This led the person in charge to show reporters the aldehyde-free test certificates obtained by Hexiang Board in China, the United States and Japan, and explained that the market called Hexiang Board as a "zero formaldehyde" plate, referring to its release; It is made of natural fibers such as straw, which contains a very small amount of natural aldehydes. Even the content of formaldehyde in rice cannot be zero. Therefore, it is more rigorous to call it "a sheet that does not release formaldehyde."
Formaldehyde-free furniture, the formulation needs to be scrutinized
So with "zero formaldehyde" plates, will there be zero formaldehyde furniture? The reporter has further understood this.
From sheet to furniture, it also needs to be processed by veneer, paint, edge banding and so on. From this fact, unless all aldehyde-free paint, aldehyde-free edge sealing, and aldehyde-free veneer are used, even if the board is "zero formaldehyde", formaldehyde will be introduced because of these processing processes. Due to process and cost constraints, complete aldehyde-free processing is difficult.
And those who questioned the "zero formaldehyde" furniture, it is from this!
"But we should distinguish between the primary and secondary problems," the technical person in charge of the furniture company surveyed said that the long-term formaldehyde release of furniture is mainly derived from the base material of artificial board. Compared with the amount of formaldehyde introduced by veneers and paints, it is very small after all. At the same time, since these formaldehyde are distributed on the surface of the furniture, most of them can be evaporated in a short period of time (2-3 weeks), so it will not cause any health hazards to the human body.
Therefore, objectively speaking, "zero formaldehyde" furniture produced from zero formaldehyde plates should be a concept of "approximately equal to zero formaldehyde", and also a simplified term used for convenience. There may be a rigorous aspect, but there is no intention to deceive consumers.
Of course, in order to avoid unnecessary business troubles, some companies still adopt a more cautious advertising slogan. For example, Kebao Boloni's Hexiang board series furniture adopts the expression "zero formaldehyde space".
"Zero formaldehyde" also need to be careful to avoid fish in muddy water
With the zero-formaldehyde household consumption gradually gaining the advocacy of many big brands and the support of consumers, plate products and furniture products under the banner of "zero-formaldehyde" in the market also have an increasing trend.
The author understands from the industry that the vast majority of Chinese wood-based panels are still not far from the E0 level standard. At present, the only ones that can achieve "zero (release) formaldehyde" and meet the requirements for furniture manufacturing and use are MDI as the adhesive, and Wanhuahe Fragrance Board as the representative. Therefore, when consumers buy "zero formaldehyde" furniture, they also need to identify more, beware of being submerged and fish in muddy water.
