Environmentally friendly materials are the primary issues that we will consider when decorating and purchasing. How do we choose environmentally friendly materials in the face of numerous decoration materials? Zero formaldehyde sheet is one of the environmentally friendly materials, but we don’t know much about it. Under such circumstances, how should we choose? Today, Xiaobian will take a look at the purchase techniques and purchase considerations of zero formaldehyde plate!
Zero formaldehyde plate buying tips
First, the main health problem that may exist in the board is also the problem of excessive formaldehyde emission. Therefore, when purchasing the sheet, it depends on the certification: the amount of formaldehyde emission E1 and E2 refers to the formaldehyde emission standard prescribed by the state. The E1 grade product can be directly used indoors, and the E2 grade product must be finished for the interior. . Plates that are not marked E1 and E2 are absolutely not used indoors. The veneer and the large core board can be divided into three grades according to their appearance and quality, such as superior products, enamel products, and qualified products.
Second, in addition to watching certification, you can also rely on feeling. The width of the core strip of the large core board should be greater than 2.5 times of the thickness. The two end joints of the adjacent two rows of core strips should be larger than 50 mm, the length of the core strip should be greater than 100 mm, the side slit of the core strip should be less than 2 mm, and the end slit should be less than 4 mm. The most straightforward way to check the glue strength of a plywood is to use a sharp flat blade to warp along the glue layer. If the glue layer is broken and the wood is not damaged, the glue strength is poor. The natural warpage of the entire panel of the veneer should be as small as possible.
Third, it is to look at the brand. In the sheet industry, some of the more well-known sheet brands are still well-received by consumers. Choosing these famous brands will have better protection.
Zero formaldehyde plate purchase points
First, the section is recognized. The “zero formaldehyde†soy protein glue sheet will have a unique dense lamellar structure in cross section. This is different from the granular structure of the particle board (particle board) or the fine and smooth section structure of the density board (MDF).
Second, smell the scent. Many new furniture still have a strong chemical taste. The new furniture made of “zero formaldehyde†soy protein glue sheet, especially the cabinet furniture, will open the door and have a faint fragrance. Identification from odor is also a simple method of identification.
Zero formaldehyde plate purchase considerations
The "zero formaldehyde" floor is not strictly investigated. It is found that the "zero formaldehyde" floor and other home building materials products on the market are expensive but attract the attention of many consumers. However, the so-called "zero formaldehyde" Can floor products really achieve formaldehyde-free?
Recently, the Consumer Council’s “Comparative Test Report on Environmental Performance of Sheets†also mentioned that several kinds of artificial “no aldehyde†artificial boards were tested, although the measured values ​​were less than the E1 and E0 levels in the national standard. However, a certain amount of formaldehyde was detected. According to industry insiders, the so-called "zero formaldehyde" concept is not a very strict statement. It can only be said that no formaldehyde was artificially added during the production of the board.
Whether it is soy protein glue, MDI ecological glue, resin adhesive, it is indeed an aldehyde-free adhesive, but it does not mean that the finished product has no formaldehyde. Experts point out that wood itself naturally contains trace amounts of formaldehyde. Can only say that no formaldehyde is added, but can not be said to be formaldehyde-free.
In the face of many plates, we must learn how to distinguish whether it is environmentally friendly, so we need to understand the purchase method before purchasing. The above is the small formaldehyde plate purchase skill and purchase considerations introduced by Xiaobian today. It is over here. For more information, please continue to pay attention to the decoration home.
