The long-term release of formaldehyde in all wood-based panel furniture is extremely harmful to the human body due to formaldehyde, and it is an unavoidable problem in the home decoration process. It has always been the focus of attention in home consumption. It is generally accepted that long-term inhalation 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, pregnant women, formaldehyde is particularly harmful.
Wood-based panel furniture is the most important and long-term source of indoor formaldehyde. Almost all wood-based panels release formaldehyde for a long time. This release will be accompanied by the life of wood-based panel furniture. China divides wood-based panels into E2 and E1 grades according to the amount of formaldehyde released. However, it is worth noting that compared with the European and American standards, the current "contract" standard on the market is still very loose. Therefore, the Chinese wood-based panel industry has also adopted the “E0 grade†standard to distinguish artificial panels with relatively small amounts of formaldehyde.
After visiting the professionals, the reporter concluded that whether it is E2, E1 or E0 standard wood-based panels, because of the continued formaldehyde release, when the room has a limited volume, large decoration density, limited ventilation conditions (especially during sleep) In the case of the bedroom, there are different degrees of risk of excessive formaldehyde. Some respondents claimed that about 80% of new homes in China are facing excessive formaldehyde. A furniture manufacturer who asked not to be named also said that if there is a "zero formaldehyde" household product in this case, it is a revolutionary solution to the health threat of formaldehyde to the living environment. Its health value to the public and its marketing value to the business will be enormous.
Market research on wood-based panels that do not use ecological adhesives are not "zero formaldehyde"
According to a panel manufacturer, the basic reason for the continuous release of formaldehyde in ordinary wood-based panels is that the manufacturing process of wood-based panels requires the use of aldehyde adhesives such as urea-formaldehyde resins. “This kind of adhesive is a direct compound of formaldehyde and urea. Because it is cheap and has good bonding effect, it is used in the manufacturing process of wood-based panels. But the biggest disadvantage of this kind of colloid is that it is under natural conditions. It will continue to spontaneously decompose and reduce, releasing free formaldehyde, and in the hot and humid environment, the decomposition and deliquescence will double the reaction rate."
"The difference between a good wood-based panel and a poor material is that eco-adhesive can replace urea-formaldehyde resin. The safety and stability of eco-adhesive can be free of formaldehyde and will not decompose free formaldehyde. The more popular 'zero formaldehyde' furniture." Some people said that "zero formaldehyde" wood-based panels still need to pass the national aldehyde-free test. In addition, the plate itself is made of natural fibers such as straw. In this natural fiber, it does contain only a small amount of natural aldehydes. "Even if the formaldehyde content of rice is not completely zero. The so-called wood-based panel produced from natural fibers. It is 'the plate that does not release formaldehyde' is more rigorous than the 'zero formaldehyde' statement."
Winning furniture sales with the "zero formaldehyde" method, pitted!
With the "zero formaldehyde" sheet, is it possible to produce "zero formaldehyde" furniture? Xiaobian further verified the industry's people.
It turns out that from sheet metal to furniture, it needs to be processed by veneering, painting and edge sealing. From this fact, unless all zero aldehyde paint, zero aldehyde edge seal, and zero aldehyde veneer are used, even if the sheet is "zero formaldehyde", formaldehyde will be introduced due to these processes. “Because of process and cost constraints, complete aldehyde-free processing is difficult to achieve.†Industry salespeople say that some “preparations†are just a propaganda to win sales.
In addition, the long-term formaldehyde release of furniture is mainly derived from wood-based panel substrates. The amount of formaldehyde introduced by veneers, paints, etc. is relatively small. The formaldehyde in the veneers and paints are distributed on the surface of the furniture, and most of them can be volatilized in a short period of time (generally 2-3 weeks), so there is no excessive health hazard to the human body.
The “zero formaldehyde†furniture produced with zero formaldehyde sheet should be a concept of “about zero formaldehyde†and a simplified title for convenience. There is one aspect that is not rigorous enough, but there is no intention to deceive consumption. Of course, there are also brand merchants who have adopted a more cautious slogan in order to avoid unnecessary business troubles, such as the use of "zero formaldehyde space".

Warnings:
1.lndoor use only.
2.To avoid being damaged,do not use water or drip irrigation while using.
3.Sunshine lighting time should be 12-18 hours.
4.While irradiating the plants,the height of led grow lamp is not less than 10 inches,
low height will cause the destruction of plants.
5.Highly hang the lamp will weaken the energy and affect the growth cycle of the
plants, so the lamp should not be hung too high.
6.While taking care of the plants, please spray the leaves and branches 2-3 times everyday,
to ensure the the plants do not wrinkle a wither, and have no phenomenon of few fruit, and
hard pericarp.
