Many owners who like DIY for home often make their own wood modeling to improve the specific needs of some local spaces

many owners who like DIY for home often make some wood modeling by themselves to improve the specific needs of some local spaces. And the boards used in home decoration are often large core boards. How to choose a good large core board is the first step of DIY! It's better to follow the reporter to the market, use a saw and nose to calculate, and you'll have a bottom in your heart

1. Ten ring certification is a green certification authorized by the State Environmental Protection Administration. When consumers buy large core boards, floors and floor accessories, they generally recognize Shihuan Peugeot, which can maximize the quality of the products purchased and avoid unnecessary losses in the future

2. The owner can ask the merchant to take out a board on site, saw off its corners, and smell its smell with his nose. If there is an obvious pungent smell, its environmental protection cannot be guaranteed naturally

3. The proportion of combined wood strips on the side of the core of a good board is relatively symmetrical, while the proportion of combined wood strips on the side of a inferior board is quite different, and there is no rule

4. If it is convenient, use a saw to cut off a corner, and then peel off the wood epidermis. Check the small wooden strips spliced inside. It should not use wood with bark, boreholes and knots. For large core boards with good quality, the connection between wood strips will be very dense

5. The specification of large core board is generally 1220mm × 2440mm, 15mm and 18mm thick are common

large core board, also known as blockboard, is one of the main materials commonly used in decoration. Because its middle is a core made of natural wood strips, and both sides are pasted with a layer of wood skin, it is called a big core board. Large core board is mainly used for the production of furniture, doors and door jambs, heating boxes, curtain covers and other indoor woodwork. Its waterproof and moisture-proof performance is better than particleboard and medium density board

environmental protection takes the lead

in home decoration, the massive application of plates is one of the main sources of indoor pollution. This is because the process of manual processing of plates often contains formaldehyde and other harmful substances. Therefore, when purchasing plates, the owner must choose the ones that meet the environmental protection level

the state has written regulations on the formaldehyde emission of plates: the formaldehyde emission of building materials directly used indoors must be less than or equal to 1.5 mg per liter, that is, to reach E1 level; If the formaldehyde emission is less than or equal to 5 mg per liter, that is, E2 grade plate, it must be treated before it can be used indoors; Formaldehyde emission exceeding 5 mg per liter is substandard

if the owner needs to use a large number of plates, the higher the environmental protection level, the better, because in a fixed space, the content of formaldehyde will accumulate because of the greater use of plates

purchase misunderstanding: smell the edges and corners to judge the quality of the plate

according to Li Ke, the manager of plate sales, when the owner purchases the plate, some businesses will let the owner smell the edges and corners of the plate. If the smell is pungent, it means that the product quality is inferior. In fact, this method seems to be simple and reasonable, but it has no substantive significance for the identification of plates after long-distance transportation and storage. Because in the process from production to sales, there is enough time for the plate to emit all the peculiar smell on the surface

purchasing skills: cutting edges and corners, smelling the smell, and looking at the test report

manager Li suggested that the owner should check the test report and on-site cutting edges and corners in order to purchase plates. The authoritative test report will clearly show the formaldehyde content in the plate. In addition, the owner can also require the merchant to take out a plate on site, saw off its corners, and then smell its smell. If there is an obvious pungent smell, its environmental protection cannot be guaranteed naturally

the structure needs to see clearly

when the owner purchases blockboard, he can only judge whether the board is flat and smooth from the appearance, whether the surface has warpage, deformation, blistering, concave convex and other phenomena, and whether there is obvious color difference. Weiwenhua, the general manager of brand plates, stressed that owners should not only grasp the environmental protection performance and surface flatness of plates, but also pay attention to the investigation of the core structure

the owner is reminded here that sometimes some inferior boards will be painted all around with paint, so that the owner can't see it from the appearance. If there is glue and putty filling around it, it means that there may be cracks or holes inside it

purchasing skills: the combination of board cores should be symmetrical

in addition to looking at the wood skin of blockboard, it is also very important to observe its structure. The proportion of combined wood strips on the side of the core of a good board is relatively symmetrical, while the proportion of combined wood strips on the side of a inferior board is quite different, and there is no rule. For a sawn corner, the owner can also peel off its wood skin and check the structure of its internal wood core. The small wooden strips spliced inside cannot use wood with bark, boreholes and knots. For large core boards with good quality, the connection between wood strips will be very dense

price is the ruler

there are many Blockboard brands on the market now, but the price difference is not great. The specification of large core board is generally 1220mm × 2440mm, sold by sheet in the market. Generally, the price of familiar brand large core board is mainly between 100 ~ 130 yuan per piece, and the price of general grade is also about 80 yuan. For large core board with a price lower than 70 yuan, insiders remind consumers to buy carefully. There are four kinds of thickness of large core board: 12mm, 15mm, 18mm and 20mm, but 15mm and 18mm are commonly used, and different thickness will also lead to different prices

tips:

a. when some owners choose large core boards, they mainly depend on the weight and price, but it's not true. The heavier the core board, the worse the quality. Because the greater the weight, the more it shows that this kind of board uses miscellaneous wood, and the large core board made of miscellaneous wood can't be nailed into the nail at all, so it can't be used

b. it is better to add the words "must comply with national standards" to the purchase contract or invoice, and at the same time, it is better to leave a sample during the construction. Once the indoor environmental pollution caused by the quality problem of the large core board is found after the completion of the project, it can be used as the basis for judging the responsibility
