PVC plywood - introduction to related knowledge of PVC plywood

In home decoration life, plywood is essential. Especially for water and heat insulation, rubber sheets are very important. There are many types of plywood on the market, but the most popular is pvc plywood. How much do you know about pvc plywood? The following editor will ask you to do a detailed introduction of pvc plywood, hoping to help you in your life. pvc plywood - pvc plywood introduction pvc plywood is a kind of veneer that is cut into large veneers along the direction of annual rings. finished plate. The number of veneer layers is an odd number, generally three to thirteen layers. Common three plywood, five plywood, nine plywood, and thirteen plywood (commonly known as three plywood, five plywood, nine plywood, thirteen plywood in the market) plate). The outermost front veneer is called the panel, the reverse is called the backplane, and the inner layer is called the core board. Pvc rubber sheet - PVC rubber sheet classification The first type of pvc rubber sheet is weather-resistant, boiling water-resistant pvc rubber sheet, which has the advantages of durability, high temperature resistance, and steam treatment; the second type of pvc rubber sheet is water-resistant pvc rubber sheet, It can be dipped in cold water and dipped in hot water for a short time; the three types of pvc rubber sheets are moisture-resistant pvc rubber sheets, which can be dipped in cold water for a short time and are suitable for indoor use at room temperature. For furniture and general construction purposes; four types of pvc plywood are not moisture-resistant pvc plywood, used in indoor conditions, general purpose pvc plywood materials are beech, basswood, ash, birch, elm, poplar, etc. . pvc plywood - pvc plywood composition principle Symmetry principle: the veneer on both sides of the symmetrical center plane, regardless of the thickness of the veneer, the number of layers, the manufacturing method, the fiber direction and the moisture content of the veneer, should correspond to each other, that is, the symmetry principle pvc The stress in different directions of the corresponding layers on both sides of the center plane of the rubber sheet is equal. Therefore, when the moisture content of the pvc rubber sheet changes, its structure is stable, and there will be no defects such as deformation and cracking; on the contrary, if there are some differences between the corresponding layers on both sides of the symmetrical center plane, it will make the veneer on both sides of the symmetrical center plane. The stress is not equal, which causes the pvc rubber sheet to deform and crack. Odd-numbered layer principle: Since the structure of pvc plywood is that the fiber directions of adjacent layers of veneers are perpendicular to each other, and must conform to the principle of symmetry, its total number of layers must be an odd number. Such as: three-layer board, five-layer board, seven-layer board, etc. When the odd-numbered pvc sheet is bent, the maximum horizontal shear stress acts on the center veneer, making it stronger. When the even-numbered pvc rubber sheet is bent, the maximum horizontal shear stress acts on the rubber layer instead of the veneer, which is easy to damage the rubber layer and reduce the strength of the pvc rubber sheet. pvc plywood - pvc plywood veneer veneer veneer is called decorative veneer veneer pvc plywood, which is to cut natural wood or technical wood into thin slices of a certain thickness, adhere to the surface of pvc plywood, and then hot-press A surface material used for interior decoration or furniture manufacturing. Common veneers are divided into natural wood veneer veneers and artificial veneer veneers. The appearance difference between artificial veneer veneer and natural wood veneer veneer is that the texture of the former is basically a straight texture or regular pattern; while the latter is a natural wood pattern with natural texture pattern, large variability and irregularity. Its characteristics: it not only has the beautiful pattern of wood, but also achieves full use of wood resources and reduces costs. Regarding the relevant knowledge of pvc plywood, the editor will ask you to introduce it here. After reading the above introduction, do you know something? With good products, our life will be guaranteed, and of course pvc plywood is no exception, otherwise it will affect our comfortable and normal life.
