从木塑复合挤出制品和木材比较来看，木塑复合材料经挤出工艺的制成品的外观和质感酷似木材，并具有和木材一样的加工性能、施工性能。制品密度在600~1000kg/m3之间，根据木纤维填充量的多少和发泡率的高低有所不同，一般在600~800kg/m3左右，和木材相当接近。含水量约为2%，而木材的含水量在12%~13%之间，与原木相比木塑复合型材具有   的抗水、抗腐蚀等功能，并且不存在木材自然的缺陷，如龟裂、翘曲、疤结、明显色差等。我们也知道，木制门窗除机械的、理化的损伤外，还有一个致合的弱点，那就是虫害的损伤，如白蚁、蠹虫等害虫的侵害，而木塑复合型材却可以抵御虫害。除此之外，挤出制品断面设计灵活，可以设计装饰性强的装饰结构和各种功能结构，而木制品的功能结构和装饰结构往往受加工方法的限制，很多装饰效果难以达到。显然，以上这些都是木塑复合挤出制品优于木材制品的地方，而且几乎无不及之处。 所以说木塑产品的未来市场蛮大的

Comparing wood-plastic composite extruded products with wood, wood-plastic composite extruded products have the same appearance and texture as wood, and have the same processing and construction properties as wood. The density of products ranges from 600 kg/m3 to 1000kg/m3. According to the amount of wood fiber filling and foaming rate, the density of products varies from 600 kg/m3 to 800kg/m3, which is close to wood. The moisture content of wood is about 2%, and the moisture content of wood is between 12% and 13%. Compared with the original wood, wood-plastic composite profiles have the functions of water resistance and corrosion resistance, and there are no guanjian.37ix.com.cnmojuggb.37ix.com.cnbaozhuangmo.37ix.com.cnmojujg.37ix.com.cn

mojublg.37ix.com.cn chuguan.37ix.com.cnnatural defects of wood, such as cracking, warping, scarring, obvious color difference, etc. We also know that in addition to mechanical and physical and chemical damage, wood doors and windows have a common weakness, that is, pest damage, such as termites, beetles and other pests, while wood-plastic composite profiles can resist pests. In addition, the cross-section design of extruded products is flexible, which can design decorative structure and various functional structures. The functional structure and decorative structure of wood products are often limited by processing methods, and many decorative effects are difficult to achieve. Obviously, these are the advantages of wood-plastic composite extrusion products over wood products, and almost all of them are inferior. So the future market of wood-plastic products is very big.
