Eco-board is divided into two concepts: narrow sense and broad sense. Eco-board in a broad sense is equivalent to melamine veneer, while eco-board in a narrow sense only refers to melamine veneer with multi-layer solid wood (plywood) and blockboard (such as Malacca, Chinese fir, paulownia, poplar, etc. ).
No matter what kind of plate, glue is needed in the manufacturing process, so the formed plate will release free formaldehyde. The eco-board itself is made of wood, and it also contains a small amount of formaldehyde. But the main choice is quality, and the environmental protection level reaches E 1 even E0, which is very safe. Moreover, compared with other boards, eco-board also has the advantage of paint-free. The advantage of not painting is that it reduces the emission of toxic and harmful substances brought by paint and is more environmentally friendly.
I hope my answer can help you! Hope to adopt!
Does the eco-board have formaldehyde?
Now many renovations will use eco-boards, which are made of wood and contain a small amount of formaldehyde. However, the quality of eco-board is mainly selected, and the environmental protection level reaches E 1 even E0, which is very safe. Let me tell you the key points of purchasing eco-boards:
1.
See if the surface of the board is bright and smooth. The surface of a good eco-board has no problems such as foaming, depression, deformation, defect, carbonization, etc., and the edge of the board is tightly treated without big gaps. In addition, good plates with qualified quality are affixed with anti-counterfeiting trademarks on the surface after leaving the factory, and the edges of the plates are marked with codes, which are stamped after inspection.
Smell
Smell the smell of eco-boards, and good eco-boards have only a faint smell of logs, which can be distributed and purchased; Poor boards will have a pungent smell, because the formaldehyde emission exceeds the standard.
ask about
Ask the merchants about the formaldehyde emission level of the eco-board and ask for the test report. The environmental protection grade of eco-board is European environmental protection standard. There are three grades, from high to low, E0, E 1 and E2, and the corresponding formaldehyde grades are E2, E 1 and E0. E2≤5mg/L, and the release of E2-grade formaldehyde per kilogram of board ≤ 5 mg; E 1≤ 1.5mg/L, and the formaldehyde emission of e1grade is less than or equal to1.5 mg; E0≤0.5mg/L, and the release of E0 grade formaldehyde is less than or equal to 0.5mg. It can be seen that eco-boards are environmentally friendly, and those that reach E0 level are the most environmentally friendly. The environmental protection grade of the eco-board you buy must reach E0 and E 1.
cut
Touch the surface of the plate by hand, whether it is smooth and textured, and whether it is uneven; Press the cardboard to test the density of the cardboard. Good eco-board density has strict standards, and it will not bend easily even under pressure.
As can be seen from the above, the eco-board actually contains formaldehyde, but as long as we pay more attention when buying, we will buy environmentally friendly products.
Does the eco-board contain much formaldehyde?
No paint without benzene, no glue without aldehyde. Do you think the furniture category is qualified? Formaldehyde in "civil" indoor first-class residential buildings specified by the state shall not exceed 0.08 per cubic meter; Class II office formaldehyde shall not exceed 0. 10 per cubic meter.
Does the eco-board have formaldehyde?
There should still be some, but I don't know what impact it will have on the overall environment.
There must be something in the plate, but it usually doesn't exceed the standard
It is suggested that if formaldehyde exceeds the standard, it should be treated with herbal diazine.
This is a professional in addition to formaldehyde, but it still needs ventilation for a certain period of time.
How harmful is formaldehyde in eco-board to people's health?
As we all know, formaldehyde is very harmful to human body. If exposed to formaldehyde for a long time, it may cause some physical discomfort: when the concentration reaches 0.06 to 0.07 mg per cubic meter of air, children will have mild asthma; When the formaldehyde content in indoor air is 0. 1 mg per cubic meter, there will be a feeling of odor and discomfort; When the formaldehyde content in indoor air reaches 0.5 mg per cubic meter, it will cause tears in eyes; When it reaches 0.6 mg per cubic meter, it will cause throat discomfort or pain; When the concentration is high, it will cause nausea and vomiting, cough, chest tightness, asthma and even pulmonary edema; When the concentration reaches 30 mg per cubic meter, it will kill people immediately. So does the eco-board contain formaldehyde? If so, will the formaldehyde content be harmful to the health? In fact, the eco-board inevitably contains formaldehyde, because no matter what kind of board is made, it will involve the use of glue. As long as glue is used, it will involve the intake of formaldehyde. But consumers can rest assured that the formaldehyde content of the ecological version is too low and will not cause any harm to the human body. Therefore, consumers can buy plates with confidence when choosing building materials.
Does the eco-board have formaldehyde? Distinguish between good and bad eco-boards.

Does the eco-board contain formaldehyde?
Eco-boards contain formaldehyde. Only the content is relatively low. The better eco-boards in China are Coconut King, Bunny Baby, New Millennium and so on, all of which have relatively standard formaldehyde content.
Do multilayer boards and eco-boards have formaldehyde?
Because formaldehyde is a chemical raw material widely used in textile industry and architectural decoration, it may be contained in wardrobes and desks. There can't be "zero formaldehyde" furniture on the market. Even if every piece of furniture and building materials meet the environmental protection standards, excessive use in a house may also cause the overall indoor pollution to exceed the standard, resulting in "superimposed pollution" after furniture combination. To be truly healthy, there must be standards higher than the standard.
Is the formaldehyde content of eco-board in China e0?
In fact, there is no E0 level in the national standard at all, and manufacturers fabricate concepts and hype to fool consumers!
What is "E0 class"? -We checked the existing national standards in China and related reference materials of advanced countries in the world. At present, there is no concept of "E0 grade" in all official reference materials, and "E0 grade" is passive water!
1, China's national standard "formaldehyde emission in interior decoration materials, wood-based panels and their products * *" GB18580—20065438+0, this compulsory national standard clearly stipulates the standard value of formaldehyde contained in wood floors and its detection methods, and the products that reach the above-mentioned mark level will not have an impact on human body and environment. Its * * * symbol is E 1 grade (measured by 40L dryer method, that is, the formaldehyde emission of E 1 grade products is ≤ 1. 5 mg/L).
2, the national recommended floor standard "impregnated paper laminated wood flooring" GB/T 18 102-2000, the standard regulation and classification of formaldehyde emission (* * * is divided into two categories), namely
Grade A impregnated paper laminated wood flooring: formaldehyde emission ≤ 9 mg/ 100 g.
Class b impregnated paper laminated wood flooring: formaldehyde emission > 9 ~ 40mg/ 100g.
3, Europe, the United States and Japan and other related standards of formaldehyde emission from wood-based panels:
● The regulation on formaldehyde emission in European MDF industry standard (EMB 3rd edition 1995).
Formaldehyde emission (perforation value): Grade A ≤9mg/ 100g,
Grade b > 9 ~ 40mg/100g
● Provisions on formaldehyde emission in European standard EN 312-1:(1996)
Formaldehyde emission (perforation value): 1 grade ≤8mg/ 100g,
Grade 2 > 8 ~ 30mg/100g
● Germany
Formaldehyde emission (perforation value): 1 grade ≤8mg/ 100g (no surface decoration),
Grade 2 > 8 ~ 30mg/100g (allowed to be listed after surface decoration)
● Japan
Japanese Agricultural Standards, Notice No.990 of the Ministry of Agriculture, Forestry and Fisheries (2000): General requirements for floors;
The average value of FC0 is 0.5 mg/L, and the maximum value is 0.7 mg/L.
FC 1 horizontal average 1.5 mg/l maximum 2. 1 mg/l.
The average value of FC3 is 5.0 mg/L, and the maximum value is 7.0 mg/L.
The inspection method is 40L dryer method.
To be sure, the E0 level here is taken out of context from the Japanese agricultural standard "FC0 level" and the Chinese national standard "E 1 level". Although it also bears the value of * * * stipulated by Japanese standards, it ignores its important link, that is, as a standard grade division, it is extremely scientific and serious, and every standard has provisions. If you meet a bad manufacturer, if it really exceeds the standard, you must treat it. Everything will be fine if you spray herbs in the forest. Nothing is absolute. Based on the above analysis, the so-called "E0 grade" floor concept introduced by individual manufacturers in the market at present is completely a quality grade mark independently fabricated by manufacturers. This kind of behavior has violated the grading mark stipulated by the current national standard and belongs to the illegal quality mark.
Will the formaldehyde of eco-paint-free board not exceed the standard?
First, open more doors and windows for ventilation.
Open the window for ventilation twice a day for at least fifteen minutes each time. This is new.
Whether to do professional indoor environmental pollution control when decorating a house.
Richard has one thing to do. Ventilation is beneficial to indoor pollutants.
Discharge, effectively reduce the concentration of pollutants, but also let the decoration materials have
Toxic and harmful gases are released as soon as possible, and the air is fresh.
Second, adsorption with activated carbon.
Activated carbon is an internationally recognized expert on drug abuse. The physical function of activated carbon is
Odor, detoxification, no chemical additives, no impact on people. Adsorption with activated carbon
You can't always open the doors and windows when fitting, and the closed space can ensure excellent suction.
Side effects. This method can be combined with other herbal medicine removal methods for comprehensive management.
The effect is better. That is, activated carbon is easily saturated, and now nano-active ore is used.
On the contrary, the natural adsorption effect of ore is good and the nano-pore size is larger.
The increase is very large. Third, using plant adsorption.
Some plants, such as chlorophytum, Eupatorium odoratum, Eupatorium odoratum, Phyllostachys pubescens and cash cow, etc.
It has a certain effect on absorbing formaldehyde. Although the effect is limited, it can
As an auxiliary means of indoor environment management
