近年来，面对森林资源逐渐减少的趋势，以及日益壮大的环保信息，引起了世界各国政府的广泛关注。因此如何采用高分子合成材料，专用成型设备加工具有仿木性能的新型建材成为国内外广泛关注的重大课题。在这种情况下；ＰＶＣ逐渐被广泛用于各种不同的领域，以弥补木材的不足。 In recent years, in the face of the declining trend of forest resources and the growing environmental protection information, it has aroused widespread concern from governments around the world. Therefore, how to use polymer synthetic materials and special molding equipment to process new building materials with wood-like properties has become a major topic at home and abroad. In this case, PVC is gradually being used in various fields to make up for the lack of wood.
