How to judge the quality of environmental protection boards?

1. See whether the environmental protection plate processing enterprises have passed the ISO14000 series environmental management system certification.

ISO14000 series environmental management system certification is a certification of the environmental impact of enterprises in processing, including the emission of waste water and waste gas, as well as the operating environment of workers, waste pollution to the environment and many other aspects, and it is also a certification for the environmental stability of the products produced by the enterprise. Jinan Changjingyuan Trading Company's environmental protection boards are all through the ISO14000 series quality certification.

2. See whether the environmental protection board has passed the China Environmental Labeling Product Certification.

China Environmental Mark Certification is the most authoritative and trustworthy environmental protection certification in China, and it is also internationally used and the highest standard certification in China. The logo is usually affixed to the back of each board by a certified company. At present, only a few domestic wood processing enterprises have passed the certification.

3. Look at the environmental protection level of the environmental protection board.

Since July 1, 2002, the state has implemented a limit on the release of formaldehyde in the board, for the products that have failed to pass the China Environmental Label certification, if the formaldehyde emission can meet the basic requirements of E1 and E2, the product can also be marketed, but the E2 level is only limited to outdoor use. In this regard, consumers should keep their eyes open, because the production cost of E2 grade is lower than that of E1 grade, therefore, when consumers buy plates, they must not be confused by the appearance of **, and mistakenly use E2 grade plates as environmentally friendly plates for interior decoration.

If the product has the above three aspects of certification, then this environmentally friendly board is a truly environmentally friendly material, and finally I would like to warn everyone, do not fall into such a misunderstanding: not the heavier the smell, the less environmentally friendly, because the release of formaldehyde is a slow process, even if you can't smell at that time, it doesn't mean that there will be no smell in the later stage of use.

Hello, buy a plate, mainly look at three pieces:

First, look at the level of environmental protection. The formaldehyde content standards that reach E0 and E1 levels can be called environmentally friendly boards.

Second, look at the quality of the plate. The surface is flat, no charring, blistering and other phenomena.

There are several main types of environmentally friendly materials.

1. Basically non-toxic and harmless.

It refers to natural decorative materials that have no or very few toxic and harmful substances and are not polluted and only have been simply processed. Such as gypsum, talc, sand, wood, some natural stones, etc.

2. Low toxicity and low emission.

It refers to the decorative materials that control the accumulation and slow release of toxic and harmful substances through processing, synthesis and other technical means, because of their slight toxicity and do not pose a danger to human health. For example, formaldehyde emission is low, and the large core board, plywood, fiberboard, etc.

3 Unknown.

Current scientific techniques and testing methods do not allow the identification and assessment of materials for the effects of their toxic substances. Such as environmentally friendly latex paint, environmentally friendly paint and other chemical synthetic materials. These materials are currently non-toxic and harmless, but with the development of science and technology, there may be a possibility of re-identification in the future.

Formaldehyde emissionsOne is the ** of formaldehyde. A small part is from the wood itself, the vast majority of which is the glue for bonding boards, and the most environmentally friendly glue on the market is water-based glue, without formaldehyde added.

The second is the basis for judging formaldehyde. The highest standard for judging the environmental protection of the board in China is ENF, but due to the difference in testing methods, it is found that Japan's F formaldehyde emission standard is more stringent.

TVOC emissionsIn addition to formaldehyde, TVOC is also one of the important bases for testing the environmental protection of plates.

At present, most domestic home furnishing companies are still based on the requirements of the national standard, even if the formaldehyde emission is up to standard, but the emission of TVOC is very high, so it is necessary to pay attention.

When decorating a new house, especially in the home cabinets, people are most concerned about environmental issues, followed by quality issues. The advantages and disadvantages of these two aspects can be directly displayed through the plate. There are so many types of plates, what kind of plates are the most environmentally friendly?

1. Solid wood board:

Solid wood board is the most environmentally friendly one of the boards, it is completely made of pure solid wood boards, no additives, glue and other chemicals are never used inside, and the finished product is made naturally, so it is very environmentally friendly. But because of this, its price is high, and the requirements for construction technology are also high. If the home is in good financial condition, you can choose solid wood panels for wooden doors and wooden floors in the home, including cabinets.

2. Finger joint plate:

Finger jointing board is also an integrated board, which refers to a kind of board made by using adhesive to grow vertically with different widths and narrownesses, and then spliced horizontally and polished on the upper and lower sides. However, there is no need to paste the plywood on both sides during production, so that the amount of glue used in production will be greatly reduced, so it is also an economical and environmentally friendly board when we make furniture.

3. Blockboard:

Blockboard, also known as the big core board or six decks, is made of two pieces of veneer internal glued splicing board, the number of layers of blockboard installation can be divided into three, five, multi-layer blockboard, blockboard is mainly a small wooden block with glue squeezed and spliced together, up and down veneer board, the glue and additives used in the production are relatively small, it is a relatively environmentally friendly board.

4. Plywood:

Plywood is also known as plywood or multi-layer board, in the production is to cut the wood into a single piece or a thin slice, after the adhesive bonding into three or more layers of board material, plywood in the production process can better use wood, but also more saving natural resources, but the more layers of this board will use the greater the amount of glue, compared to the degree of environmental protection is also worse.

5. Particleboard:

Particleboard production is mainly made of wood chips and some plant fibers mixed with glue and pressed at high temperature, for particleboard is mainly composed of three layers, the two sides are mainly fine particles, and the middle is relatively large particles, but particleboard will use larger glue in the production process, because a large amount of formaldehyde will also be produced, because after using this board to make furniture, free formaldehyde will be released more or less.

6. MDF:

MDF is also known as fiberboard, mainly wood fiber or some other plant fiber as raw material, after crushing in the addition of glue and high temperature pressing, this kind of board will also use more glue in the production of the project, so it is difficult to control the degree of environmental protection.

At present, when we choose the plate, we can look at the environmental protection degree of the board, the lower the grade, the proof that the plate is worth buying, which is also the only criterion for distinguishing the quality of the plate.

1. Look at the environmental protection level, the environmental protection level is to see the formaldehyde emission of the plate, and the environmental protection level is divided into three grades: E1 level ( ( , when decorating at home, it is recommended to choose a plate product with a higher environmental protection grade;

2. Kanban material sense; The smooth and delicate texture of the board is as smooth and delicate as possible;

3. Look at the plate brand, the plate brand is also a standard that needs to be considered when purchasing the plate; For example: the national brand "Top 100 Plates".

4. Look at the test report, when the merchant introduces the plate to consumers, it is best to let the merchant show the corresponding formaldehyde content test report.

At present, formaldehyde-free sheets have appeared on the market. In the production process, no harmful substances such as formaldehyde and benzene are added, and the standard can be reached to the ready-to-install standard. Consumers can give preference to formaldehyde-free sheets when choosing plates.

There is no need to prescribe the degree of environmental protection. Everyone should be aware of this. The top ten well-known brands of custom furniture Olaf board are green and environmentally friendly.

Among them, the eco-board is E0 level environmental protection level, and the environmental protection level of Olaf furniture board has been upgraded again to reach the formaldehyde-free level. If possible, choose a plate product with a high environmental protection grade.

<>After all, only by controlling the environmental protection of the substrate can we lay the foundation for the overall environmental protection of the home environmentSafety signs. Generally, the plate brand size metropolis is enough to make this anti-counterfeiting logo, and it can also avoid consumers from buying"Fakes", so that's what we can look at as well.

If there is no anti-counterfeiting logo, it can mean that the brand scale is not large enough, and it can also indicate that there may be fakes, and we are unwilling to buy inferior plates, so we should pay more attention in the purchase process. What happens in a cross-section. The plate will have a cross-section.

In general, you can see the situation with the core material. If there is a free eco-board, it is not recommended to buy it. You can also touch it.

If you feel burrs and rough socks, it is not recommended to buy them. : Brand is also a criterion to consider when choosing a sheet.

Try to choose some manufacturers who only do high environmental protection levels. Whether it is transported in the production workshop or warehouse, it is a high environmental protection standard and is not easy to be polluted by low-end plates. When purchasing, it is best to ask the merchant to show the relevant test report of the plate and the manufacturer's authorization letter to prevent buying fakes.

Do a detailed interpretation of the problem, I hope it will help you, if you have any questions, you can leave me a message in the comment area, you can comment with me more, if there is something wrong with Kai Zaoji**, you can also interact with me more, if you like the author, you can also follow me, your like is the biggest help to me, thank you.

Environmentally friendly board purchase skills.

1.Smell the smell.

If there is a pungent smell, then the limb splitting indicates that the release of formaldehyde is high, that is to say, the formaldehyde exceeds the standard seriously, so it is absolutely not optional.

2.Look at the report.

Environmental protection board must have the State Environmental Protection Administration's green environmental protection material ten ring certification mark, wooden furniture is a must need agency test report, in the purchase, should let the business provide the corresponding certificate and product manual.

3.than environmentally friendly.

There is an accurate standard for the amount of formaldehyde released in the board, and the national standard for indoor wood is E1 level, which means that the amount of formaldehyde released is there; At the same time, after the decoration is completed, it is best to ventilate for three months before moving in. Before moving in, you can check the quality of the air first. In the selection of materials, it is also necessary to choose environmentally friendly and pollution-free building materials.

It can be judged according to the ingredient material and production process of the material, which will determine the quality of a material and whether it is environmentally friendly.

Environmental protection boards are generally relatively hard, and they are particularly smooth to the touch, but those that are not good are usually rougher

The color of the surface of a good edge banding strip is also very important, whether the color is close to the customized product and gorgeous. If the surface is very rough and there are pull marks, the quality is definitely not good, which is the surface quality of the edge banding strip. It has little to do with the quality of the internal material of the edge banding strip, mainly the production process of the edge banding strip factory and the production technical skills of the employees.

A good edge banding strip is: the surface must be smooth, no blistering or very little blistering, no or very little drawing, with a moderate gloss, not too shiny or too matte.

2. Look at the flatness of the surface and bottom surface of the edge banding.

If it is uneven, it will cause the glue line at the junction of the edge banding strip and the plate to be too eye-catching, or the gap between the plate and the edge banding strip will be too large, which will affect the overall effect.

How to quickly distinguish the quality of a plate?

The selection of high-quality boards directly affects the final effect of decoration.

One look: the defects of the Kanban surface, the quality of the appearance, the advantages and disadvantages of the interior;

Second touch: feel the flatness and smoothness of the board surface, is there any uneven phenomenon?

Three smells: is there a pungent and pungent smell, and does it intuitively feel environmentally friendly?

Four listening: Knock on different positions, is the sound uneven?

1. Environmental performance. The main thing that determines the environmental performance of the board is the amount of formaldehyde released. There are two main standards in the relevant standards promulgated by the state, one is the E1 level standard, and the other is the E2 level standard.

In other words, according to the environmental performance, the board can be divided into E1 environmental protection level board, and E2 level environmental protection board. And this E1 and E2 are different according to the type of plate.

2. Look at the static bending strength of the plate. The static bending strength of the plate is a more professional term, and the static bending strength is the ratio of the bending moment and the modulus of the bending section of the specimen under the maximum load. Professional people may not understand, but to put it simply, the strength of static bending determines whether the board you buy will bend and break after a long time.

The strength of the static zone is relatively large, which means that the plate is small under the same use conditions, and the possibility of bending and cracking is relatively small.

3. Look at the water absorption of the plate and expand. According to the relevant national standards, the water absorption expansion rate of the plate should be less than 8%, and only the water absorption expansion rate is less than 8%. However, when buying plates, we can't just look at a standard, in addition to looking at the low water absorption expansion rate of not less than 8%, but also look at how the edge of the plate is, such as whether there is overflow glue, whether the edge banding is falling off.

The edge sealing of the plate is not good, even if the water absorption and expansion rate of the plate is low, the plate will still swell. On the contrary, if the edge of the plate is very good and water vapor cannot enter, then the probability of its expansion is relatively small.

4. Look at the screw holding force of the plate. The grip force of the plate determines whether the screw will loosen, fall off and burst the edge after being driven into the plate. For our decoration, it determines whether the hardware will fall after being booked into the cabinet and whether the cabinet will be deformed.

Look at the quality of the plate nail holding force, the detection method is very simple, open the cabinet door, sit on it, and see if the screw shed of the cabinet door is nailed out without loosening, if there is loosening, it proves that the screw holding force of the plate is not very good, if there is no movement at all, it means that the screw holding force of the plate is better.

5. Selection of types of plates. The main boards on the market are particleboard, plywood, MDF and blockboard. Among them, particleboard is a board with a long history, and the industry technology is relatively mature.

The strength of the quiet zone of plywood is high, but the formaldehyde content is relatively high; MDF is easy to process, but the nail grip is poor. Blockboard** is cheap, but it is not as good as the above boards in terms of performance. When choosing, it is recommended that you choose particleboard.
