Raw material of Particle board.1.Particleboard is made on the basis of scrap materials, but the range of scrap materials is relatively wide. According to different types of scrap materials, particleboard can be divided into wood particleboard, bagasse particleboard, flax chipboard, cotton stalk particleboard, Bamboo particle board, etc., cement particle board, gypsum particle board. It can be seen that most of the scraps contain wood cellulose.

What is the difference between particleboard and MDF?Nowadays, there are more and more types of furniture on the market, and furniture panels are also emerging in an endless stream. Consumers consider their panels in detail when purchasing furniture. Do you know what is the main difference between MDF and Particleboard? Let’s take a look at the differences between them.Particleboard:Particleboard is a kind of man-made board that is glued together under the action of heat and pressure after adhesive is applied.

Advantages of MDF1. The internal structure is uniform, the density is moderate, the dimensional stability is good, the deformation is small, and the physical and mechanical properties are moderate.2. The surface is smooth and smooth, with good machining performance. It can be pasted with sliced veneer, patterns and novel and beautiful decorative papers. Therefore, it is very popular in home decoration and is often used to make furniture and partitions.3. It can be used as the middle frame and middle clip strip in the modern decorative frameless painting.

     The density of medium density board is between the density of high density board and low density board, generally 650~880kg/m. The common specification is 2440mm*1220mm, and the thickness is 1mm, 3mm, 5mm, 9mm, 12mm, 15mm, 18mm, 25mm, etc. . MDF with other special specifications and thicknesses can also be customized.How to identify high-quality MDF?1.Surface cleanliness: There should be no obvious particles on the surface of the density board with good surface cleanliness.

What are the characteristics of high-strength particleboard?The high-strength particleboard adopts the two-stage chipping technology combining the drum chipper and the shaving chipper. The size of the shavings produced by this technology is rich, and it is very easy to change the length of the wood chips. It can effectively use small-diameter materials and save wood resources.

Everyone knows that density board is widely used in making furniture or decorating partitions because of its uniform structure, fine material, stable performance and easy processing. Everyone is curious, how to distinguish the quality of density board?Let me tell you something.1. Surface cleanliness: There should be no obvious particles on the surface of the density board with good surface cleanliness. Particles are caused by impurities brought in during the pressing process, which not only affects the appearance, but also makes the paint film easy to peel off.2.

What is Black Core HDF?    The Black Core HDF floor is a floor made of this carbon crystal.    Carbon crystal is a kind of microcrystalline carbon particles purified from minerals, commonly known as high carbon graphite.

Product performance    The most advanced flat pressing production line in the world. Therefore, the physical performance is higher and better than that of MDF. Its density is usually above 800kg/M3. The high-density fiberboard produced has reached 930kg/M3, which has reached the advanced level of similar products in Europe and America.     The board surface texture is fine and smooth. When the ambient temperature and humidity change, the size stability is good, and the surface decoration treatment is easy.

      The Invention of Wood-based Panels     The invention of wood-based panels can be traced back to 3000 BC. At the beginning of the 1st century BC, the Romans were already familiar with veneer manufacturing technology and plywood manufacturing principles.     In 1812, the French invented the veneer sawing machine.     In 1834, France issued a planer patent.     After 1844, the improved rotary cutting machine was officially used in industrial production.

Decoration Particle Board Introduction:Particle board is made of wood or other lignocellulosic materials, applied adhesive and then glued together under the action of heat and pressure, also known as shredded board. It is mainly used in furniture manufacturing, construction industry and train and carriage manufacturing.Decoration Particle Board Advantages:A. Good sound absorption, sound insulation and thermal insulation properties;B. The internal granular crossed and staggered structure, the performance of each direction is basically the same, and the lateral bearing capacity is good;C.

The differences between flame-retardant MDF and ordinary MDF are analyzed one by one as follows: 1. Color The color of flame-retardant MDF is dyed with red dye, so red MDF is not necessarily flame-retardant MDF Board, this point cannot be identified. 2. Physical and mechanical properties Due to the addition of flame retardants, the water-absorbing expansion of the board is affected to a certain extent. Therefore, testing the water-absorbing expansion coefficient of the board can preliminarily judge whether the flame-retardant MDF can meet the use requirements.

     Particleboard, also known as chipboard, is a wood-based panel that is made of wood or other lignocellulosic materials and glued under heat and pressure after applying an adhesive.

    Particleboard, also known as chipboard, flakeboard, is a wood-based panel that is made of wood or other lignocellulosic materials and glued under heat and pressure after applying an adhesive. It is mainly used in furniture manufacturing and construction industry as well as train and car carriage manufacturing.Method for judging the quality of particleboard wardrobes1. From the appearance point of view, look at the size and shape of the sawdust particles in the center of the cross section. The length is generally 5-10MM.

Today I will tell you which one is better, E1 density board or E2, and the characteristics of MDF?Which is better, E1 density board or E2?    Since the glue used in the processing process will release carcinogenic formaldehyde, standards have been formulated according to the amount of formaldehyde released, including European standards, national standards, and American standards.

Oriented strand board is a new type of high-strength environmental protection board. Under the background of the prominent structural contradiction between the supply and demand of wood in my country and the prevalence of green environmental protection concepts, oriented strand board relies on a wide range of material sources, advanced production technology, and excellent mechanical properties.

The production of chipboard in China has gone through a repeated process from the rise in the 1980s to the decline in the 1990s and then to the rise again in 2000.    After the particle board was abandoned by the market due to poor quality and other reasons, many particle board enterprises learned a lesson, introduced advanced production lines from abroad and improved the technology level.   After that, the quality of particle board in China has improved significantly, and it has been accepted by the market again.

An Introduction to OSB Board      OSB is Oriented Strand Board ,the upgrading of traditional particle board.

What is OSB ?Oriented Strand Board (OSB) is a kind of fresh wood with large diameter and straight trunk as raw material. It is processed along the direction of wood grain by special slicing processing equipment.

The raw materials for making particleboard include wood or wood fiber materials, adhesives and additives. The former accounts for more than 90% of the dry weight of the board. The wood raw materials are mostly taken from felled wood in the forest area, small diameter wood (usually less than 8 cm in diameter), felling residues and wood processing residues. Wood chips, shavings, wood filaments, sawdust, etc. processed into flakes, strips, needles and granules are called chips.

   The production of chipboard in China has gone through a repeated process from the rise in the 1980s to the decline in the 1990s and then to the rise again in 2000. After the particle board was abandoned by the market due to poor quality and other reasons, many particle board enterprises learned a lesson, introduced advanced production lines from abroad and improved the technology level.    After that, the quality of particle board in China has improved significantly, and it has been accepted by the market again.

    Oriented strand board (OSB), also known as Ozon board, originated in the 1970s and developed from structural particle board-waffle board. Since the mid-1980s, it has developed rapidly in North America and Europe, and has begun to replace plywood in large quantities. For use with fiberboard.    Oriented strand board is a new type of high-strength environmental protection board.

Characteristics of OSB1. Wide sources of raw materials and low prices.The raw materials of directional particle board are mainly small diameter wood of soft coniferous wood and broad-leaf wood, fast-growing thinning forest, such as eucalyptus, Chinese fir, poplar thinning wood, etc., with a wide range of sources.2. High output rateCompared with other types of wood-based boards, oriented particle board has a higher output rate.

With the continuous development of science and technology, carbon crystal panels or Black Core MDF, as a new type of decoration material, have gradually attracted people's attention. So, what are the advantages and disadvantages of Black Core MDF in whole house decoration? Let's take a look together.First, the advantages of Black Core MDF1).
