Price disparity
People who have experience in home improvement know the blockboard, which can be used to make furniture, make closets and doors, and can also be used for ceilings. In addition, it also has a certain load-bearing function, and has decorative properties, which has become an indispensable product for home decoration. But buying a blockboard is a headache. Look at things, the price is a lot worse, and people are overwhelmed. Many people think that there is not much problem with such a simple board. If you buy expensive ones, you can save a lot of money by saving a lot of money. Industry insiders have recently warned that in fact, the seemingly simple blockboard is not simple.
Invisible core flower head
The reporter recently strolled around the Zhejiang Building Materials Market and found that most of the dealerships did not indicate the basic information such as the name, price and specifications of the plates sold, so that people who do not know how to do it can't figure it out. The only one is clearly priced, and in addition to the name, specification and price, the label also specifically indicates the environmental protection factor is the Senlu boutique space Jinhua store. It is understood that the store is the general distributor of Senlu plate in Jinhua. For the blockboard market, general manager Chen Xinggao summed up the phrase “mixed fishâ€.
According to reports, the current price of blockboard on the Jinhua market ranges from 50 to 170 yuan per piece, and the disparity in price is greatly learned in the quality of the core. For example, the thickness of the core in the middle of the 18th blockboard is 60% to 80% of the main part, and the quality varies greatly. Good quality blockboard like Senlu brand blockboard is made of high quality wood, imported equipment, flat surface, no gaps from any angle, no need to deal with furniture, but the price Higher, generally more than 100 yuan per piece. Many small enterprises and non-standard enterprises have made a "brain-building" on the core of the board. They used some woods containing dead knots, side skins and even decay to make the core. In an unannounced visit, CCTV found five homes from Xingtai, Hebei Province. The blockboard produced by the wood company is made of wood scraps, small slats and sawdust. Because these cores are inside, the people can't see them. For this reason, it affects the strength of the board. If consumers use such materials to make bed plates, the strength will not be collapsed. If the furniture is made, it will break easily. Such a poor quality board, the price is only 50 ~ 70 yuan / Zhang, the carpenter to get such a board will generally do some veneer processing, that is, put a layer of panels on both sides of the blockboard. In order to purchase such a blockboard, in addition to the cost of the blockboard itself, the cost of the panel is added, and the carpenter calculates the salary according to the number of the board. No matter what board, the wages of the board must be calculated according to the number of sheets. Once calculated, the total price actually paid by consumers far exceeds the price of a good-quality blockboard.
Environmental protection factor has standards
The hazards of formaldehyde are well known, so many people will use the nose to smell when buying plates. In fact, China's formaldehyde release limits for wood-based panels and products are standard. The national standard "Dermization Limit of Formaldehyde in Artificial Panels and Products for Interior Decoration Materials" stipulates that E1 ≤ 1.5 mg / liter, which can be directly used indoors; E2 ≤ 5.0 mg / liter, which must be used for interior treatment. There is also a class E0 formaldehyde-free blockboard, which is sampled by the National Wood-based Panel Quality Supervision Center. The formaldehyde emission is 0.3 mg/L. The industry believes that E0 is a new industry health standard that can be considered safer along with health and safety standards for food, drinking water and other related products.
Despite the national standard, there are still problems in the market that are unclear. Ask the dealer, some will tell you that it is green, or first-class and second-class. Since it is not clearly marked, the air pollution caused by the consumers in the unknown will happen from time to time, and thus disputes may occur. In addition, the problem of unclear grades is also prominent. Now there are 3B and 5A blockboards on the market. The average consumer simply cannot figure out what the logo is a good product. The reporter saw that the Mori deer blockboard with a specification of 2440×1220×18 and an environmental protection factor of E1 was priced at 145 yuan per piece, and the same environmental protection factor but the price of 2440×1220×15 was 138 yuan/ Zhang. This price is naturally much higher than those of the blockboard that are not marked and the formaldehyde is exceeded.
Glue also has environmental protection factor
At present, most of the blockboard manufacturers still use traditional glue, which is not only used by Chinese companies, but also used all over the world. With this glue, there will be some formaldehyde present. Chen Xinggao told reporters that the glue used in the blockboard also has a standard, using E1 standard glue, 15 pieceboard, and using 600 tons of heavy pressure for half an hour. Using E0 standard glue, 15 pieceboards, use 600 tons of heavy pressure for 45 minutes. Use E2 standard glue, 15 blockboards, and press with 600 tons of pressure for 3 minutes. The rubber used by many non-standard enterprises can't even reach the E2 standard, and the quality of the blockboard produced is naturally worrying. Moreover, since the used adhesive is unqualified, it is easy to cause the product to open, which also affects the consumer's use function.
Process is not standardized, quality is difficult to guarantee
Another problem that cannot be ignored is the moisture content of the core. Some of the coreboards produced by non-standard enterprises use ordinary natural drying processes, so that the products produced can not be scientifically controlled to control the moisture content of wood, and it is easy to bend and deform during use, which is often Consumers have reported that the furniture has been deformed for a short time, and the nails fall off. The quality of the blockboard is mostly mechanical degreasing and drying process, so that the moisture content of the wood is kept consistent, ensuring that the product does not deform and crack, and the flatness is very good.
Another outstanding problem is that the actual thickness of the product does not match the manufacturer's commitment. For example, the manufacturer claims that the 18th thick blockboard is actually measured to be only 16th thick, which indicates that some irregular companies have fraud. On the one hand, it can't satisfy the consumer's use function, on the other hand it defrauds consumers. There is no such problem in regulating the products produced by enterprises.
Choose the blockboard to see the details
The first is to look at the appearance. The appearance should be smooth and flawless, and the label should be complete. One side of the blockboard must be a whole piece of wood, and only one seam is allowed on the other side. The quality of the blockboard panel should be dry, smooth, and free of defects, such as no dead knot, excavation, leakage, etc. The thickness of the middle plate is uniform, no overlap, separation of seams, and the splicing of the core board is tight, especially the blockboard. There must be no cracking at the end. Place it upright, the corners should be straight, and the diagonal error should not exceed 6 mm. The entire package of blockboard should fit completely between each board. Secondly, touch the surface of the blockboard by hand. The high quality blockboard should be dry and smooth.
The second is to look at the internal quality. Observing the light, such as whitening, the stitching of the wooden strip is not tight enough; when the sound is picked up, there is a squeaking sound indicating that the bonding strength is not good; lifting one end of the blockboard, licking it, the quality blockboard should have a A sense of overallity and a sense of weight. Of course, this kind of heavy induction is a good one when the hand feels dry, otherwise the dryness is not enough. Then use a sharp-nosed instrument to strike the surface of the board to see if there is a big difference in the sound. If the sound changes, there is a hole inside the board. These phenomena will weaken the overall bearing capacity of the board, and the long-term uneven force will cause the sheet structure to be distorted and deformed, affecting the appearance and use effect. In addition, if the blockboard is made of environmentally-friendly glue, the production site will only smell the wood after drying, and it will not smell the pungent formaldehyde. If the blockboard emits a pungent odor, it indicates that the amount of formaldehyde released is high, so it is best not to buy it. Check the quality inside and look at the corner. A large-quality core board with good quality, in which the small wooden strips are connected by a zigzag-shaped jaw, the gap of which cannot exceed 5 mm.
Chen Xinggao concluded that the thickness of one point is hard, and the thinner the sheet, the more deformed. The quality of the board is good and the substrate is very important. The cedar tree is hard and the density of poplar is a bit loose. The surface should be smooth and the texture should be natural. The so-called one dragon and nine sons are different, and the natural color difference is the nature. The wood board substrate should look at the core, and the hollow bark is annoying. If you want to use materials, you must ask for quality. It is wrong to buy a layer of leather. The plate is not only good-looking, but the inner quality is the key. Process equipment and management, the big factory small factory is tens of millions, choose a brand is a shortcut. To buy authentic plates, the brand is looking for a monopoly. There is no phoenix in the chicken coop, and the grocery store can't tell the truth. Quality issues are a problem, and retaining credentials is key. Commitment cards and shipping orders, a lot of them are all.
