Guide: There are many kinds of lamination materials for wood furniture, such as lamination lamination, melamine lamination, fireproof board lamination, etc.
In addition, there is a kind of plastic lamination, namely PVC lamination. The laminationing of the wood furniture board can play a certain role in beautification, which can cover the defects on the surface of the wood furniture board, improve the grade of the board, and also improve the aging resistance of the board. To a certain extent, it can slow down the impact of water, oxidation, temperature and other factors, and greatly extend its service life. In addition, it can also protect the surface of the wood furniture board, improve its surface performance, and greatly reduce the impact of external environmental factors on the board.

Precautions for PVC facing: The density of the base material is required to be uniform. If the base material is not flat and smooth, the amount of glue absorbed after gluing will be uneven, resulting in local or large areas of bubbles. At this time, the higher the ambient temperature, the larger and more bubbles will be, which will affect the quality of PVC facing. It is required to apply glue evenly and appropriately in the PVC overlay. The requirements for applying glue are very high. It should be uniform and have a certain thickness, otherwise the best glue will also cause degumming. At present, modified polyvinyl acetate white latex is still widely used. If this adhesive is applied too thin, it will not stick firmly. However, if the coating is too thick, it will also have a negative effect, that is, it is not easy to dry. Therefore, it is important to maintain an appropriate amount of glue and a better drying time. It is not allowed to move the PVC lamination before it is completely dried. The edge of the panel is easy to unglue and the middle is foaming. The determination of drying time varies greatly due to the different types of glue used, the thickness of glue coating, the quality of substrate, and the temperature and humidity of the environment. How to determine a better drying time should not be generalized by all plants. The ideal drying time can be determined by doing a simple drying tear test. After PVC coating, the coating has not reached the time of complete drying. If the temperature has risen to above 22 ℃, the latex will be easy to soften and the viscosity will drop sharply. As a result, the curved edges of the parts are more likely to unglue and become “ear edges”. Advantages of wood furniture PVC laminationed wood furniture can also achieve high quality. In the process of wood wood furniture processing, if the PVC lamination is used, if the process means are correct and the processing is fine, the quality level that can be achieved is often more than that of the wood furniture coated with paint. In particular, the imported high-quality PVC is overlaid. Due to its stable quality, realistic wood grain, three-dimensional sense, no color difference on the surface, no knots and other defects, and the use of high-quality glue, the products made can also belong to the high-end series. With the popularity of PVC laminationed wood furniture, new varieties of PVC artificial wood have been continuously developed to replace natural wood. It is recommended to improve the quality of PVC lamination. First, after the PVC overlay is completed, the plates shall be placed for a week for aging or fully dried, and then cured thoroughly. The plates shall be delivered and transported after the internal stress is removed and the plates reach equilibrium. Secondly, other processes related to lamination are adopted to enhance the fastness of lamination and improve the stability of product quality, such as post forming and soft forming edge sealing processes. How to improve the quality of PVC laminations There are many varieties of PVC laminations, and their quality varies greatly, including PVC for general purposes and PVC for special purposes, such as anti scalding, fire protection, wear resistance, high strength (tear resistance), etc. Although the surface texture and color of some PVC lamination materials are the same, their quality is different. The price difference of PVC of the same size is even 7~8 times, and similar problems exist in imported PVC.
