Let's look at environmental protection and environmental protection According to the requirements of the formaldehyde release limit for artificial decoration materials and artificial products used in interior decoration materials from January 1, this year, the amount of formaldehyde released from building materials directly used indoors must be less than or equal to 1.5 liters per litre. In milligrams, if the amount of formaldehyde released is less than or equal to 5 milligrams per liter, it must be treated with veneer before it can be used indoors. Formaldehyde emissions exceeding 5 milligrams per liter are substandard. Bringing unqualified wood home is like adding a gas generator to a new home. It must be environmentally friendly to buy building materials. {TodayHot}
1. Blockboard "Daixinban": moisture-proof effect is good, can not be directly painted blockboard middle of the core is a natural wood stick together, on both sides of a very thin veneer, as the name suggests Daxinban, is One of the most important materials in the decoration. Can do furniture and package doors and door covers, heating covers, curtain boxes, etc., its waterproof and moisture-proof performance is better than particleboard and MDF. When looking at the interior of the wood, it should not be crushed. It is advisable to use a fine board with a gap of about 3 mm between the wood. 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. Daxinban is divided into 3, 5, and 9 centimeters board thickness, {HotTag} 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.
The low price of Daxin board, 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 price of a large core board sold at a price of 50-55 yuan can not be used at all.
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 you choose the big core board, you must cut a corner to 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.
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.
2. Laminated wood, not easily deformed This is a new type of solid wood material, using high-quality imported large-diameter logs, deep processing and imaging as the staggered splicing of wood panels. Due to different processes, the environmental performance of this kind of board is superior. It is 1/8 that the large core board allows the amount of formaldehyde, and the price is about 200 yuan each, which is slightly more expensive than the high-grade big core board.
But on the other hand, this type of wood made from American spruce and other solid wood can be painted and brushed directly, eliminating the need for a process compared to a large core board. Finally, the cost of construction may be flat.
3, MDF than chipboard nailing poor particleboard is a natural wood crushed into pellets, after pressing into the board, is the main material of the current cabinet. The medium density board is formed by pressing wood chips and has good flatness but poor moisture resistance.
In contrast, the density of the MDF is lower than that of the chipboard. If loosening occurs after the screw is tightened, the strength of the MDF is not high enough to fix it. Therefore, it is rarely used as a cabinet.
4, decorative plywood saves money and cheap plywood, also known as plywood and plywood, different layers are different names. According to the thickness of 3-9 cm, it can also be called 3-9 PCT board. Its advantages and disadvantages mainly depends on the raw materials. The price of a 1.2m to 4m plate per Liu'an core is between 10 to 20 yuan. The mahogany and poplar will be cheaper.
At present, the main use in home improvement is a decorative plywood, that is, a very thin solid wood veneer has been attached to the plywood in the factory. The decorative plywood is easy to use and the price is cheaper than buying the veneer panel for the construction team.
5, melamine double board, not afraid of fire and water on both sides of this board are shiny, very hard, afraid of water and fire, mainly used in furniture and cabinets, the price is more expensive.
6, decorative panels, manufacturing and solid wood effect of the veneer is wood grain with high-grade wood peeling veneer, very thin, the thinnest only 0.3mm, thick but also 2-3mm. The color of common veneer is from light to dark, with dozens of cherry, maple, white peony, red peony, ash, white oak, red oak, teak, rosewood, walnut, white shadow wood, red shadow wood, etc. The varieties are expensive.
For large areas, it is best to buy veneer plywood directly. If the panel is to be used locally for unique effects, a higher process is required.
When buying wood with water content up to standard and treated wood when the moisture content of the wood is higher than the equilibrium moisture content of the environment (annual average moisture content in Beijing is 11.4%), the wood will dry and contract, otherwise it will absorb moisture and expand. The main reason for the cracking and deformation of wood is that the moisture content is too high or too low. Qualified wood needs to go through the factory's high-temperature cooking and drying procedures to finally reach the local moisture level. Therefore, the moisture content of wood is particularly important.
Experts reminded: Do not map cheap experts told us: Do not map cheap, very low-priced materials are usually crude and excessive formaldehyde excessive material. It is best to purchase in the formal market, where the purchase channels are more secure. Buy branded materials. Since wood is the main material in home decoration, the number of purchases is large, and care should be taken when buying. It is best to go with experienced people or professional buyers. Can also commission the decoration company to buy, first, they have a stable quality supplier, the price may be lower, and second, once the quality problems, the responsibility is clear, the problem is resolved.
