I will definitely use it

Last Tuesday, the girl wrote an article "Businessmen's solid wood VS your solid wood" , many friends said: After reading it, they found that they bought not solid wood furniture, but composite sheet furniture, and asked me if I want to return it.
But what did the composite sheet do wrong?
Here the two girls have to correct one thing: composite boards are very, very common materials in wooden furniture, not that they cannot be used. The purpose of the second girl to write solid wood furniture for everyone is to avoid pits for everyone, not to be fooled by the merchants using "solid wood" gimmicks.
Compared with solid wood, composite panels seem to be born with the original sin of "formaldehyde" and "non-environmental protection". However, as the second girl wrote in the previous article:
The composite board can be used in such a large amount, and also has its advantages. These composite plates have low cost, stable performance, are not easily deformed and cracked, and are easy to process . I am also a furniture manufacturer and I like to use them.
Especially in the custom furniture industry, most of the custom furniture, the raw materials are composite panels.
As this fan said:
Han Han
You do n’t have to go for solid wood at all. Now the plates are graded. The E0 and E1 grades are the ones with very low formaldehyde content. Buying the brand ’s plate furniture is not a big problem. Even the water contains formaldehyde. No more drinking.
In recent years, because of everyone ’s concern about the problem of formaldehyde and the importance of environmental protection, the composite board family is also expanding: solid wood multilayer board, particle board, ecological board ... Each merchant will tell you that this board is very formaldehyde. Few, our Barabara that meets the E0 standard, you are confused.
Today, the second girl came to clarify these terms that the business is fooling you. Let me tell you carefully. If you do not choose solid wood, how should you choose the most environmentally friendly composite board?
Again , instead of thinking about how to remove formaldehyde every day, it is better to try to reduce the presence of formaldehyde from the source.
Before saying composite board
Let me talk about their glue first
Putting the glue first is because everyone knows that the main source of formaldehyde in composite sheets is those adhesives.
Therefore, there is a common misconception that less glue is used for environmental protection. In fact, it is not necessarily, the key is to see what glue is used.
Adhesives commonly used in composite panels are urea-formaldehyde resin, phenolic resin, melamine formaldehyde resin, MDI (isocyanate adhesive), and sometimes other. Basically, to determine whether the glue contains formaldehyde, just look for the word containing aldehyde.
Therefore, urea-formaldehyde resin, phenolic resin, and melamine formaldehyde resin all contain formaldehyde, and MDI does not contain formaldehyde , so many composite plates using MDI, such as Hexiang board, can claim to be "zero formaldehyde".
But this does not mean that MDI is very environmentally friendly and safe. It does not contain formaldehyde, but it still contains other chemical components and has certain toxicity . However, this is low toxicity , and it is much less harmful to humans than formaldehyde.
They may have various flower names
But all are composite plates
Composite plate mainly refers to a plate made of crushed wood / wood chips / wood fibers and various adhesives. The general substrates are divided into four types: particle board, density board, plywood and blockboard.
These substrates need to be further processed, such as skinning, edge banding, finishing, scraping, polishing ... A variety of chemical agents containing aldehydes and benzene are used in these processes.
So everyone must make sure that some substrates (such as Hexiang board, Ou Song board) are indeed formaldehyde-free, but the final furniture will still detect formaldehyde, why? Because it also depends on whether the aldehyde-based adhesive is used in the subsequent processing process, and whether the benzene-based paint is used ...
Hey, the two girls couldn't help but feel that it's really not easy to live safely ...
Particle board
Particle boards, also known as particle boards, are sometimes referred to as "solid wood particle boards" (in fact, you know), which are the most used boards on the market and are also commonly used in foreign countries.
The main material is wood scrap, which is made by adhesive bonding.
Compared with other materials, particle board is the cheapest, has the highest adhesive content, and has the shortest service life.
However, it has a stable structure, low cost, and convenient processing. It is a good idea for major furniture brands and custom furniture brands.
IKEA also has a lot of chipboard used for furniture, of course, this does not prevent others from expanding to all parts of the world.
There are some derivative products of particle board: Ousong board, EGGER board.
Ousong Board, also known as Oriented Strand Board (OSB) , is a board imported from abroad. The adhesive used is isocyanate (PMDI), which is free of formaldehyde.
But as the second girl said before, the board will be further processed, so the final product may still contain some formaldehyde, which is much lower than the ordinary board.
The general particle board is made of broken wood, and the pine board is made of wood chips (which can also be seen from the picture), so it has the advantages of convenient processing compared to the general particle board. Both have improved.
Two girls' anti-pit tips
Because Ousong board is more popular, there are also domestic OSB boards known as Ousong board in China, and the materials used will be different from imported ones.
The authentic Ou Song board was introduced and registered by Beixin Group. Please pay attention to the merchants when buying.
In addition to Ou Song board, EGGER board is also imported particle board, the formaldehyde emission is much less than domestic particle board (0.3mg / L), so it is also more environmentally friendly.
In addition, the veneer of EGGER is better, and the texture and texture of the finished product are close to solid wood. This kind of environmentally friendly, high value plate, of course ... is expensive.
MDF
The wood fiber or non-wood fiber is glued together with adhesive, which is the MDF. Various names sometimes used by merchants: MDF (medium density fiberboard), fiberboard are all MDF.
There is also Hexiang board , which is popular in recent years, is also density board. It does not use wood fiber, it is broken straw, so many businesses promote its natural environmental protection.
In fact, the reason why it can be called zero formaldehyde is because the adhesive used is MDI, which does not contain formaldehyde . But as the second girl said in the previous section, the absence of formaldehyde does not mean that there is no toxicity. Even if the Hexiang board is used, it is better to ventilate and smell as much as possible.
The advantage of MDF is that it is not easy to crack, and the disadvantage is that it is easy to get wet, and it will swell and deform when wet (please pay special attention to friends who return to the sky in the south) , so it is more suitable for cabinet doors, not suitable for cabinets.
Plywood
A fan in the background asked the second girl "What is a solid wood multilayer board? "
Stick the veneer with an adhesive, three layers of plywood and five layers of plywood, which looks like chocolate wafer biscuits (hungry).
Plywood has good stability and durability, and is easy to process. Compared with MDF and particle board, it has better strength and is more moisture-proof.
Blockboard
The board with the most flower names , such as large core board, wood core board and wood board . After splicing with wooden strips, the two sides are glued with thin wooden boards, so the glue content is slightly less .
The quality of blockboard is very different, mainly depends on the type of wood used for splicing. The better ones might be poplar, birch, pine, and Malacca, so the so-called Malacca deck is also a type of blockboard.
The inferior ones will be spliced ​​with various kinds of miscellaneous wood, and will not even give you a strict fight, anyway, there are wooden boards on both sides to cover, you can't see it.
Blockboard is divided into three grades of first, second, and third according to international regulations. If you want to choose blockboard, it is best to ask the merchant about the quality level. You can also weigh yourself, if the material is too light, it may be untrue.
Ecological board
@ 木木 木 肖
Second girl, I'm working on decoration recently. I heard about a situation where many manufacturers would sell an eco-board as solid wood. If they are asked if they are eco-boards, they will deny ... Two girls can talk about ecology Board?
Ecological board is a kind of artificial board, not solid wood . However, this name is very confusing, and many people think that this kind of plate is more environmentally friendly.
Then you really think too much.
The ecological board is also called paint-free board . Its board base material is particle board, density board, plywood, blockboard, etc., but it does not use paint, but uses paper soaked in melamine resin adhesive to decorate the wood surface .
Therefore, the environmental protection of the ring depends on the adhesive of the substrate, and the aldehyde glue is still used in the production process, so you know ...
In the past, this product was called melamine board, but later because of the poisonous milk powder incident, it was renamed and changed to the ecological board.
Composite sheet contains formaldehyde
Then I must not use it
In the previous article of solid wood furniture, the second girl mentioned that everyone actually does not need to smell formaldehyde and change color. The formaldehyde content in the safe range is not harmful to the human body. In fact, in nature and your life, there are formaldehyde, nail polish, some shampoos, plastic basins, newly purchased clothes sheets ...
The state stipulates that the indoor formaldehyde content should be less than 0.1mg / m3, and formaldehyde exceeding the standard will poison the human body.
Even in the composite panel industry, they are also classified as environmental protection grades . This is the various grade standards that businesses of all kinds often use when they are bragging about the panel with you.
There are four commonly used standards in China: China, the European Union, the United States, and Japan. The second girl helped you to make a table (Quickly praise the intimate second girl!). When you choose the plate, you can check it according to this table.
The more popular environmental protection plates in China, such as EGGER and Lushuihe plates, are based on European E1 environmental protection standards.
One more thing to say here, because the quality of domestic plates is uneven, so when you buy plates, do n’t listen to the words of the merchants, and they must let them show the plate test report or quality inspection certificate.
Attentive fans may find that even for E0 grade boards, the formaldehyde content is higher than the indoor formaldehyde content (0.1mg / m3) specified by the state.
So even if you buy sheet furniture with very low formaldehyde content, you still need to pay attention to ventilation and live for a while. The advantage of E0 grade sheet is that the ventilation time can be shorter!
Compared with sheet metal
Edge banding is equally important
In addition to using an adhesive with less formaldehyde, there is another way to reduce the amount of formaldehyde released, which is dense edge banding.
Simply put, if the edge banding is good, the formaldehyde can be firmly enclosed in the plate, even if it leaks a little, it is within the safe range.
Maybe some people have to ask, then can't you not just seal the edges and let formaldehyde emit light as much as possible?
First of all, think about how many furniture and building materials you need to disperse formaldehyde. If you want to wait for these formaldehyde to release light, then your new house may be reserved for your next generation.
Secondly, edge banding is not only to seal formaldehyde, but also to avoid moisture and mildew on the board.
Among the edge banding materials, the more environmentally friendly is ABS edge banding , but the most common one is PVC edge banding, the reason is of course cheap.
PVC edge banding
There are also natural wood strips that may be used to disguise solid wood.
When buying a board, you must not forget to check the edge banding to see how firm it is and the amount of glue used.
Backstage fans have been asking the second girl what furniture brand is the most environmentally friendly. Please forgive the second girl for not giving an answer directly, because no matter what brand they are, they will have different material classifications and price grades.
No matter what board you choose in the end, for your own safety, try to use non-formaldehyde glue, E0 or E1 grade board, strict edge sealing, ABS edge sealing is better.
Huai'an Furniture Net-gojiaju.com Huai'an Station hopes that everyone can choose according to their own needs. Don't be scared by the various terms of the business. Choose the furniture that suits you best and lay out your own. Warm little family.
