The difference between the excellent and special products of Xinzhongjie woodworking board

Millennium Boat Blockboard Yuan Millennium Boat Fir Integrated Board Yuan Millennium Boat Fir Integrated Board 70 Yuan The blockboard is 58 yuan, the black walnut is 78 yuan, and the ash is 36 yuan.

There are E0, E1, E2 grades, and there are no grades for the lower grades, and it is best not to use the three grades.

Blockboard can be divided into EO grade, E1 grade, E2 grade according to environmental protection standards, according to the latest national standard for blockboard (GB T5849-2006).

The formaldehyde emission of EO grade is , the formaldehyde emission of E1 grade is , and the formaldehyde emission of E2 grade is 5mg L.

Among them, the E0 grade blockboard has the highest environmental protection level, but the technical requirements are also very high, and it is much higher, even some large-scale manufacturers are difficult to do.

In the first and more moderate degree of environmental protection is the E1 grade blockboard, which is currently a more mainstream product, more expensive than E1, but the degree of environmental protection is higher, for the sake of health, it is worth it. E2 grade blockboard is not recommended for purchase.

1. The specifications of the large core board are 1220 mm (mm) * 2440 mm (mm).

2. There are three kinds of thickness of the large core board, namely: 18 mm (mm mm) (mm mm (mm).

The large core board refers to what we call the woodworking board in daily life, which is made of two pieces of veneer and then glued and spliced in the middle, it is cut into strips of the original wood, and then spliced into a core, and then processed and made into the current large core board.

The size of the large core board is generally 2440cm (length) * 1220cm (width), and its thickness generally includes 12cm cm cm. The ** of this kind of large core board is generally about 100 sheets.

At present, most of the popular large core boards in the building materials market are solid, glued and assembled, and double-sided frosted five-layer boards, with a standard size of 1220mm*2440mm. The large core board can be divided into cm board according to the thickness, and the industry mainly chooses the appropriate large core board according to the pressure of the large core board and the strength value of the large core board itself.

Expand your information;

Blockboard, commonly known as large core board, is made of two pieces of veneer glued together in the middle. The total thickness of the two-sided adhesive veneer of the blockboard shall not be less than 3mm.

The width of the corner defects of all kinds of blockboards within the nominal format shall not exceed 5mm, and the length shall not be greater than 20mm. The intermediate plank is made of high-quality natural wood planks after heat treatment (i.e., drying in the drying room), processed into wood strips of a certain specification, which are spliced by a puzzle machine. The spliced wooden board is covered with two layers of high-quality veneer on both sides, and then glued by cold and hot presses.

The core bar accounts for more than 60% of the volume of the blockboard, which has a lot to do with the quality of the blockboard. It is best to use the tree species that manufacture the core bar with soft material, uniform wood structure, small deformation, small dry shrinkage rate, and small difference between the tangential and radial dry shrinkage rate of wood, easy to process, the size and shape of the core bar are more accurate, the finished board surface is smooth, the board is not easy to deform, and the weight is lighter, which is conducive to use.

Generally, the moisture content of the core strip is 8%-12%, the air drying in the north can be 6%-12%, and the air humidity in the southern region is high, but not more than 15%.

The production process of the core.

Dry Panels=== Double Side Planer=== Multi-rip saws=== Cross-cut saws=== Core bars.

1) Core thickness: the thickness of the wood core board plus the machining allowance of planing the board surface when manufacturing the wood core board.

2) Core width: the width of the core board is generally a thickness of times, it is best not to exceed 2 times, some high quality requirements of the blockboard core width can not be greater than 20mm, the wider the core, when the moisture content changes, the greater the deformation of the core.

3) Core length: The longer the core, the higher the longitudinal bending strength of the blockboard, but the longer the core, the lower the wood utilization.

4) The material of the core strip: the core strip is not allowed to have resin leakage, decay, and creeping.

5) Processing of core board: the use of core glue machine, after the wood core board glue spelling, the board surface is rough and uneven, usually using planer processing, core processing precision high machine wood core board, can be sanded to replace planing.

The standard specification of the large core board is 2240mm 1220mm.

The thickness is generally 19mm, 22mm, 25mm, etc.

Large core board generally refers to blockboard: refers to a special plywood made of wood slats spliced or hollow core board on the basis of plywood production, covered with two or more layers of plywood on both sides, and made of glue pressing, the characteristics of blockboard are mainly determined by the core board structure, which is widely used in furniture manufacturing, sewing machine benches, carriages, ships, etc.

The existing standard size of Dawang coconut woodworking board is 1220*2440mm, the thickness is, and the pressure bearing capacity of different thickness woodworking boards is also different, so you should choose according to your actual situation to buy, and also pay attention to quality and environmental protection issues.

Woodworking board is now the basic material for furniture and decoration modeling, one side is a better thin plywood, one side is slightly worse, and the middle is broken wood. The quality of the woodworking board depends on whether the broken wood blocks in the middle are dense, the denser the better, which can effectively prevent deformation, and the more expensive it is. Plywood is now mainly used on the outer surface of the molding, such as the curved place, which has good bendability.

Plywood generally has plywood, plywood, plywood, etc. One is a layer, and there are also called three centimeter plates, etc., and one centimeter is a layer with a thickness of 1mm. Each layer of veneer is 90° vertical, which increases strength and reduces deformation.

Blockboard, also known as large core board, is one of the main varieties of wood-based panels for decoration. According to experts, blockboard is a board made of natural rotary cut veneer and solid wood panel, which is glued and hot-pressed. According to the quality of the material and the texture of the surface material, it can be divided into "excellent product", "first-class product" and "qualified product".

There are also many kinds of materials such as poplar, birch, pine, and paulownia. The surface material can be one or two layers of veneer on both sides of the board core, which can be classified into three-layer blockboard and five-layer blockboard. In the production process of blockboard, there will be problems such as excessive formaldehyde emissions, unqualified transverse static bending strength, unqualified product moisture content, and low gluing strength.

Both are the same. Woodworking board is a large core board, and blockboard is called a large core board. The large core board is a special sandwich plywood, which is one of the most commonly used boards in the current decoration, and is generally used with decorative panel fireproof board and other surface materials.

Product naming of blockboard: named after the panel tree species and whether the core of the board is glued. If the panel is ash veneer, the blockboard with the core is not glued and called ash.

Classification and nomenclature of blockboard: according to the core structure: solid blockboard; Hollow blockboard.

According to the splicing condition of the board core: glue blockboard; Do not glue blockboard. According to the surface processing condition:

single-sided sanded blockboard; double-sided sanded blockboard; Do not sanding blockboards. According to the use environment: indoor blockboard; Blockboard for outdoor use.

According to the number of layers: three-layer blockboard; five-layer blockboard; Multi-layer blockboard. By application:

Ordinary blockboards; Blockboard for construction.

The surface of the board is smooth, the texture is hard, there is no bark and no gaps in the cut, and the general thickness is centimeters.

It is better to choose a machine puzzle. The middle sandwich of the large core board is solid wood, and there are two kinds of manual assembly and machine assembly when making, and the machine assembled board is more uniform.

Blockboard is divided into two types: hand-assembled and machine-assembled, and the quality is quite different. The core of the blockboard assembled by the machine is compact, there is no gap, the specific gravity is large, and the flatness is good after sanding on both sides during processing; There is also a set of gluing, pre-pressing and hot pressing processes in the process, which can withstand the test of thermal expansion and cold contraction, and basically will not be glued and cracked.

At present, the hand puzzle is basically the product of some small manufacturers, most of the gluing quality is poor, the manual puzzle is not tight enough, the cold pressing method is adopted, it is easy to deform, degumming, cracking, its surface is relatively rough, and the core board may appear in neutral. The ** of hand puzzle is about 30%-40% cheaper than machine puzzle.

When consumers buy, they should pay attention to prevent the phenomenon of buying hand puzzles with machine puzzles, don't just look at the trimming, inferior boards will be modified at the trimming to confuse consumers.

Good Malacca. Mid-range willow eucalyptus, mahogany, camphor, and also good poplar. Hand-prushed panels, miscellaneous wooden boards.

Just use Penghong's. We use that all the time.

Blockboard refers to a special kind of plywood made of wood slats spliced or hollow core board as the core board on the basis of plywood production, covered with two or more layers of plywood on both sides, and glued and pressed.

The characteristics of blockboard are mainly determined by the core board structure. It is widely used in furniture manufacturing, production of sewing machine plates, carriages, ships, etc., and in the construction industry.

According to the current definition, blockboard refers to a special plywood made of wood slats spliced or hollow core board as the core board, covered with two or more layers of plywood on both sides, and pressed by glue. The characteristics of blockboard are mainly determined by the core board structure. It is now widely used in furniture manufacturing, production of sewing machine plates, carriages, ships, etc., as well as in the construction industry.

2. mm, mm: mainly used as a bed in furniture, a combination cabinet, a bookcase, a computer desk, a desk and a side panel, the most widely used and the most used;

3. mm, mm: thicker, generally used to make wooden doors and other places.

Blockboard is one of the fastest-growing wood-based panels in China. At present, blockboards on the market mainly have problems such as surface flatness, thickness deviation and warpage deformation. In recent years, the production process of medium and high-grade blockboards has been constantly changing in order to improve product quality.

The blockboard has good screw holding force, high strength, has the characteristics of firm quality, sound absorption, heat insulation, etc., and the moisture content is not high, between 10% and 13%, easy to process, and the most widely used.

The blockboard has good screw holding force, high strength, and has the characteristics of solid quality, sound absorption, heat insulation, etc., and the process requirements of blockboard are very high, which not only requires enough space to allow the wood to have enough time to adapt to natural drying, but also to carry out strict drying process control through the drying kiln.

Extended Materials.

Blockboard usually refers to 15mm woodworking board, which is generally 13mm due to the manufacturer's cutting corners

The seed board is mainly used for cabinet doors.

Also known as a large core board, it is generally 18 mm thick and has certain standard specifications.

Those who make furniture are mainly cabinets, and they must be sawed to know if they are good or not.

How much is a blockboard? What are the specifications and classifications of blockboards?

1. According to the thickness: the size and size of the blockboard are 1220mm*2440mm, and the thickness is from 1cm to 2cm.

2. According to the environmental protection level, it is divided into three types: E2, E1 and E0; E0 is the most environmentally friendly.

The above two kinds of procurement are very intuitive, ask directly, the seller can not do fake, the most difficult to control the general purchase of woodworking board is the material, what to do with what kind of board to buy, the following is a brief introduction to the three, generally remember these three can meet the conventional decoration needs.

Third, according to the material: the woodworking board has a greater impact on the woodworking board itself (what wood core is used), and the commonly used woodworking board ** comparison (with thickness as the standard) is as follows:

1. Miscellaneous wood core: made of miscellaneous wood, there are many hollow places in the middle, some places are strong, some places are soft, can not be forced, easy to deform, but the cheapest. Generally 85 95 yuan, the decoration to build a temporary fence, for the construction of the operating table, for modeling or fixing the temporary fixed plate and so on.

2. Fir core: all use fir trees as cores, vertical splicing, neat and tight wood, nails are generally not empty, and the deformation range is small, **100 150 yuan. This is generally used for bar bases, cabinets, door and window covers.

3. Eucalyptus core and Malacca core: Eucalyptus and Malacca are both arbors, the biggest feature is that they are not deformed, the texture is very very soft, and the first is relatively high, 110 160 yuan. It is generally used as a cabinet door or a wooden product with high requirements for deformation.
