背景技术Background technique
衣柜，橱柜，办公桌的主体板材使用三聚氰胺板，密度板或刨花板，但由于不同型号产品的尺寸不一样，在制作过程中都需要按照不同尺寸把主体板材锯开，那么锯开的部分就是裸露的板芯，严重影响产品的外观，所以就需要包边材料把裸露的板芯部分包住，包边的好坏也是衡量衣柜质量的一个重要标准。另外，包边材料还对柜体的变形起着重要的作用，所以衣柜的包边材料还需要一定的强度，刚性等要求。The main board of the wardrobe, cabinet, and desk uses melamine board, MDF or particle board. However, due to the different sizes of different models, the main board needs to be sawed according to different sizes during the manufacturing process, so the sawed part is bare. The core of the board seriously affects the appearance of the product, so it is necessary to wrap the bare core part of the edging material. The quality of the edging is also an important criterion for measuring the quality of the wardrobe. In addition, the edging material also plays an important role in the deformation of the cabinet, so the edging material of the wardrobe also requires a certain strength, rigidity and the like.
目前，主要是采用铝合金包边条应用在衣柜，橱柜，办公桌等方面。与钢材相比，铝合金具有材料轻，强度高，密闭性能好，耐腐蚀效果好，安装时变形小等优点，但是铝合金包边材料也存在以下不足之处：铝合金包边材料的生产能耗高，保温隔热、隔音效果差，材料密度大，颜色单一，而且在安装时，工艺复杂。At present, the main use of aluminum alloy edging strips in the wardrobe, cabinets, desks and so on. Compared with steel, aluminum alloy has the advantages of light material, high strength, good sealing performance, good corrosion resistance and small deformation during installation. However, the aluminum alloy edging material also has the following shortcomings: the production of aluminum alloy edging material High energy consumption, poor thermal insulation, poor sound insulation, high material density, single color, and complicated process during installation.
