Daxinban, also known as blockboard, because of its use of plastic hardwood as a core board, and then outside the skin, as the name suggests Daxinban. At present, Daxin board is the leading product of China's decorative sheet and is widely used in interior decoration fields such as: closets, door frames, window frames, furniture, curtain boxes, heating covers, and cabinets. Its waterproof and moisture-proof performance is better than particleboard and medium density board.
The large core board has a small density, small deformation, high strength, and good dimensional stability, so it is widely used. Blockboard middle of the wood material generally poplar, Tongmu, Chinese fir, Liuan, white pine and so on. The surface of the high-quality product is smooth and smooth, without degumming, sanding, indentation, small thickness deviation, and no obvious hollow core after sawing.
Advantages: simple processing technology, good nail holding power.
Disadvantages: Due to the influence of the processing technology, the vertical bending resistance is poor and the horizontal direction is better according to the direction of the core material. In addition, the moisture content is high; the formaldehyde content is also high, and it must be treated before it can be used safely.
Daxinban is used in a large number of interior decoration, and many consumers should pay attention to the process of purchasing Daxinban. What are the errors? How can I buy a good product that I am comfortable with but can rest assured? Don't tell you now. You'll know when you look.
The first principle of purchase: look at environmental protection is not environmentally friendly. It is an indisputable fact that the content of formaldehyde in Daxin board is high. After the country imposes restrictions on the amount of harmful substances for decoration, the adhesive used for large core boards must be improved. Therefore, it can be said that it is impossible to manufacture genuine green environmental protection large core boards with a price of 50 to 60 yuan, which is in line with the national standard E1 level. Daxinban, about 90 yuan is already a meager profit. Home decoration can only use E1 level Daxin board.
Look at the internal wood of the core board when picking it up. It should not be too crushed. It is advisable to use a blockboard with a gap of about 3 mm between the boards. Due to the unsightly appearance of the wood grain on the surface, it is seldom to paint directly. Usually, a decorative plywood is to be applied. Wooden furniture such as furniture made with a large core board must go through two processes of using glue boards and paint, and the cost is higher. Daxin board is divided into 3, 5, 9 PCT boards according to thickness, we can choose according to the pressure and intensity under pressure, the thicker the higher the price.
Many consumers choose Daxin board, a look at weight, and second look at price. In fact, the heavier the big core board, the worse the quality. The greater the weight, the more it shows that the board is made of miscellaneous wood. This type of large core board made of wood cannot be used because it cannot be nailed.
In addition, the low price of Daxin Ban, its quality will certainly be very poor. Not a big gap, it is the use of unqualified wood. So when you choose, it is best to choose a 100 yuan a big core board. The price of Daixinban, its relatively stable quality. The market is sold at a price of 50-55 yuan a big core board, simply can not be used.
The first choice is to look at the appearance of the big core board: one side of the big core board must be a whole board of wood, and the other side only allows one patchwork. In addition, the surface of the large core board must be dry and clean.
In addition, when consumers choose large core boards, they must cut a corner and check the quality inside. The small wooden strips spliced ​​inside cannot have a gap of more than 5 mm. Wood with bark, holes and dead knots cannot be used. Good quality large core boards, among which there are sawtooth shaped mouthpieces, are connected together.
Tips for selection: The high formaldehyde content of the blockboard, and the national compulsory installation of harmful substances in the decoration limit, the adhesive used for the big core board must be improved, so it can be said that the real green environmental protection core board is fifty to sixty yuan. It is impossible to manufacture E1 grade Daxinban that meets the national standards. The 90 yuan is already a meager profit. Home decoration can only use E1 level Daxin board. If the product is an E2 grade large core board, even if it is a qualified product, its formaldehyde content may be more than three times that of an E1 grade large core board.
According to relevant sources, the phenomena of brand name branding on the current market, such as the “Golden Autumn†brand with the largest sales volume in the Beijing sheet market, seems to be the most popular: “Golden Autumnâ€, “Year of Autumnâ€, “Hebei Golden Autumn†and “Langfang Golden Autumn "Autumn Building Materials" and other names abound, and they all call themselves the "Golden Autumn" brand, but in reality they are hard to distinguish. To this end, the relevant experts suggested that: When choosing a large core board to look at four:
A look at whether it is a regular manufacturer's product. To view the manufacturer's trademark, production address, anti-counterfeit signs, etc.;
Secondly, see if the formaldehyde emission in the product test report is less than or equal to 1.5 mg per litre. General regular manufacturers have test reports, formaldehyde detection values ​​should be as low as possible;
Third, look at the appearance quality of Daxin board. To see whether the surface of the Daxin board is smooth, whether it is warped or deformed, whether there is bubbling or depression, whether the arrangement of the core strips is even and orderly, and where the gap is as small as possible, whether the core strips are decayed, broken, wormholes, thrifty, etc. Under normal circumstances, the inner quality of the large core board with good appearance is correspondingly better.
Four to see if there is odor. If the big core board emits the odor of wood itself, it shows that the release of formaldehyde is less; if the smell is pungent or aromatic, it shows that the formaldehyde emission is more.
About Daxin board's buying skills, I would probably say here, I believe you have to buy to meet their own requirements and health and environmental protection of the big core board must be full of confidence, let's talk about Daxinban in the use of home decoration Pay attention to some issues.
In use, the big core board can only "shun open" on the long side and cannot be used sideways. In addition, Daxinban cannot be used as a panel, and a layer of plywood should be used as a panel on the outside, otherwise there will be problems such as paint blistering.
Home decoration can only use E1 level Daxin board. If the product is an E2 grade large core board, even if it is a qualified product, its formaldehyde content may be more than three times that of the E1 grade large core board, so it cannot be used for home decoration. Once again, it is necessary to purify and seal large-core boards that cannot be finished, especially in the back-sheets for decoration, various interior panels, and heating covers. Currently, experts have developed formaldehyde sealants, formaldehyde-enclosed waxes, and elimination Closed formaldehyde aerosols are best used for decoration. However, if the amount of E1 class large core board is too large, it may cause the indoor total formaldehyde content to exceed the standard, so even if it meets the standards, it does not necessarily absolutely harm the human body. Generally about 100 square meters of room use large core board not more than 20, while also taking into account other indoor decoration, if used too much will cause formaldehyde in the indoor environment exceeded. In particular, do not use a large core board as a liner below the floor to avoid excessive formaldehyde in the indoor air.
