[ Chinese wardrobe net ] wardrobe has become a must-have furniture in home life, people's requirements for the wardrobe are constantly improving, not only requires the personalized design of the wardrobe, reliable quality, but also requires environmental protection and health. Here we have to talk about the panels of the wardrobe, which is one of the important factors to ensure the quality of the wardrobe itself and environmental health. At present, the wardrobes on the market are mainly made of artificial boards, and few of them are made of solid wood. The wood-based panels are further divided into particleboard, fiberboard and large core panels. Among them, fiberboard has high density, medium density and low density.
Solid wood particle board (particle board)
The particleboard is broken by logs and processed by high temperature and high pressure. The middle layer of the particleboard is wood chips, and the two sides are finely organized wood chips, which are pressed into plates. The surface layer is in the form of a powder layer, and the homogenized particle board is the best. The molecular structure of the particle board is tight and the bending strength is high.
Advantages: good nail holding power, and adhesive content less than 5%, environmental protection. High strength and stability, it is also one of the mainstream artificial stencils in the European furniture market.
Disadvantages: The flatness of solid wood particle board is not as good as that of MDF. It is more difficult to make curvature such as curvature. Because the method is easy to make, the quality is different, it is difficult to distinguish. The edge of the particle board is rough, easy to absorb moisture, the density is loose and easy to loose, the nail holding power is low, and the amount of glue is large. Only the high quality imported particle board meets the highest European E1 standard. The formaldehyde content is less than 0.9 mg/100 m.
MDF (MDF)
Plant fiber is the raw material, and the plate made by the process of fiber separation, sizing, drying, paving, hot pressing, sawing and inspection is one of the leading products of artificial board. The surface has good flatness, good stability, high bearing capacity, and superior strength and hardness than particleboard. The internal structure of the fiberboard is uniform, the density is moderate, the dimensional stability is good, and the deformation is small. Therefore, the nail holding force is strong, and it can be disassembled and assembled many times, which is convenient for moving. Moreover, the melamine-finished fiberboard has the characteristics of moisture proof, anti-corrosion, wear resistance, high temperature resistance, etc., and does not require post-treatment, and the formaldehyde content is low.
Advantages: The material is thinner for edge sealing and it is not easy to open the glue. It's easier to make a shape, usually with more door panels or back panels. The mainstream price is around 250 yuan - 350 yuan / square meter.
Disadvantages: More glue is used than particle board, which is more likely to cause environmental problems. The moisture resistance is poor, and the water is easily deformed.
Blockboard (large core board)
The blockboard is commonly known as the large core board, which is made up of two pieces of veneer laminated in the middle. The middle wood board is processed into a certain specification of wood strips after being heat treated by high quality natural wood boards.
Advantages: Compared with particleboard and medium density fiberboard, blockboard has natural wood characteristics that are more in line with human natural requirements. It has the advantages of light weight, easy processing, good nail holding power and no deformation. It is made of interior decoration and high-grade furniture. Ideal material.
Disadvantages: In the production process of blockboard, there will be problems such as excessive formaldehyde emission, unacceptable transverse static bending strength, unqualified product moisture content, and low bonding strength.
Splint (plywood)
The line is commonly known as the thin core board. A three-layer or three-layer thin sheet made by cutting a log into a veneer or a wood chip, and then cutting it into a thin wood and then bonding it with an adhesive. An odd number of veneers are usually used, and the fiber directions of adjacent layer veneers are vertically aligned and glued to each other.
Advantages: The hardness of the splint is generally high. Since the material and the texture have been vertically staggered in the gluing process, the strength is large and the deformation is not easy.
Disadvantages: Each layer of plywood is glued together, so its environmental protection is relatively poor.
Different plates are compared with each other:
What kind of board is the most environmentally friendly? Many consumers believe that particleboard is more environmentally friendly than MDF. However, it is not the case. The plates used in the panel furniture are mainly particleboard and MDF. These two kinds of plates are made by hand, made of wood processing and crushed with adhesive, and the environmental protection degree naturally depends on the environmental protection of the glue. When consumers customize furniture, they are often misled by salespeople in the store. Sales staff often use larger particle size of the particle board, less glue on the board, and the MDF is pressed with powdered fiber, the particles are small, and more adhesive is needed. The particle board is naturally more environmentally friendly than the MDF. In fact, the environmental protection of MDF and particleboard that meets national standards is the same. There is no such thing as the most environmentally friendly statement.
The difference between particleboard and MDF is that the substrate of the particleboard is not completely pulverized into fibers, but is pulverized into granules, which is named after the shavings, and then pressed by an adhesive. The MDF is obtained by completely pulverizing the substrate into a fibrous form and then adding an adhesive. However, the particle board is pressed by the shaving material and added to the adhesive, so the density is not uniform, the middle is low, and the two ends are high, so the holding force is lower than that of the medium density fiberboard. Moreover, the surface of the MDF is relatively fine, and the flatness is higher than that of the particle board. The cost of particleboard is lower than the cost of MDF, so the price of particleboard is lower than that of MDF. Therefore, qualified MDF and particleboard are only functionally different, and there is no more environmentally friendly statement.
Slicer and dicer(meat dicer) are used in different fields of food industrial such as for meat, cheese, vegetables, fruits etc. Helper`s slicer and dicer seies are applied in both restaurant and industrial plant. To produce portioned bacon, the Rib chopper will help. To make vegatable and meat mixture for dumpling production, QD02 vegetable dicer will be the best choice.
In addition to them,we also supply the cubing machines.
