Let formaldehyde "dance in shackles"

Among the well-known chemical products, formaldehyde may have the most media "favor".
However, this "destiny" is mostly built by his negative image.
For example, the Market Supervision Bureau of Wuxi City, Jiangsu Province recently announced the situation of unqualified products in the field of circulation in 2018.
Among them, many products in the field of sheet products were found to have unqualified formaldehyde emissions, including some that declared "no aldehyde addition.
" Brand products.
The “no aldehyde addition” routines developed by the merchants actually illustrate the contradictory nature of formaldehyde itself-although it is widely used, it does not want to be known.
It depends on the nature of formaldehyde.
In terms of "use", formaldehyde has the reputation of "all-rounder in the chemical industry".
It can not only be directly used as disinfection, sterilization, and antiseptic, but also in organic synthesis, synthetic materials, coatings, rubber, pesticides and other industries.
However, along with "use", formaldehyde also has obvious "over": volatile gases are inhaled into the human body, which can cause respiratory diseases, and long-term inhalation will cause symptoms of poisoning and other potential health hazards.
Based on this, formaldehyde never dared to take credit for arrogance, but kept a "low profile", even "incognito.
"Formaldehyde exists as a contradiction between pros and cons.
Obviously, it cannot be beaten to death with one stick.
The correct attitude is to weigh the pros and cons and promote the pros and cons.
There is a famous saying in toxicology: Talking about toxicity without the dose is a hooliganism.
For the judgment of formaldehyde, a dose standard should also be established.
In fact, based on scientific experiments and clinical observations, the academic community has found that as long as the amount of formaldehyde released is controlled within a certain range, the harm to the human body is minimal.
Drawing a line with this "small amount" as a reference is the limit standard.
Generally, the level of formaldehyde emission limit is divided into three levels: E0, E1, and E2 in the world.
It is very safe to reach E1 level.
The mandatory standard "Limits of Formaldehyde Release in Wood-Based Panels and Products of Interior Decoration Materials" that my country has implemented from May 1, 2018, has all the limit values ​​up to E1 level.
  Under strict standards, formaldehyde is like "dancing in shackles".
Although it is staggering, it also shows a different kind of beauty.
  What needs to be explained is that formaldehyde is not only a chemical product, but also a substance that can be produced by nature.
The air, water and wood in life all contain formaldehyde.
Therefore, the "aldehyde-free" environment is almost non-existent.
For the most stringent E0 level, "0" is not "no content".
This standard also gives a limit value of less than 0.
5 mg per liter, which is equivalent to the formaldehyde content in the mineral water or beer we usually drink.
Knowing this truth, you know that some businesses engage in so-called "aldehyde-free" propaganda.
They are all deceiving people and should not be taken seriously.
The group standard T/CNFPIA3002-2018 "Formaldehyde-free wood-based panels and their products" issued in August 2018, in which "formaldehyde-free" means that wood-based panels should not use adhesives with formaldehyde raw materials during the production process.
This is the definition of "aldehyde-free" from the production process and product testing, and does not mean that the product does not emit formaldehyde.
  In addition to adhesives, materials containing formaldehyde may be used in the production process of panels and furniture that need to undergo substrate treatment, coating and other processing links.
If you want products to achieve excellent environmental performance, all production links need to be "aldehyde-free".
From the current domestic technical level and production environment, this is almost an impossible task.
It is reported that in recent years, my country has successfully developed formaldehyde-free non-iron finishing agents and formaldehyde-free environmentally friendly urea-formaldehyde resins.
However, they have not been put into mass production today.
There are two main reasons: first, this type of product has better performance.
Poor, the second is expensive.
It can be seen that the replacement of formaldehyde is a very difficult and slow process, which also determines that formaldehyde’s "shackled dance show" will continue to be performed for a long time.
  Of course, letting formaldehyde "dance in shackles" will inevitably restrain the hands and feet of some enterprises and merchants, and affect their profit-seeking.
At this time, some businesses will use their brains.
We have seen that some companies do not produce according to standards and use inferior raw materials in the production process, causing the product to emit formaldehyde exceeding the standard; there are also businesses that make "zero formaldehyde" and "no formaldehyde addition" and other gimmicks to mislead consumers and engage in unfair competition.
  These chaos remind relevant departments that the production and management of products involving formaldehyde must not be taken lightly, and strict standards and requirements must be strict.
On the one hand, it is necessary to establish a more scientific and reasonable standard system to plug loopholes in regulations; on the other hand, it is necessary to strengthen supervision and strict law enforcement, so that manufacturers of formaldehyde exceeding the standard can be drilled seamlessly, and they will be punished.
