摘要:
An extruded composite artificial lumber product is manufactured from wood fibers, a polyethylene matrix and a foaming agent. A mixture is extruded through a molding die which forms the profile of the desired product. The endothermic foaming agent causes greater expansion in the center of the extruded profile and increased density at the outer edges of the extruded profile.
摘要(中):
挤出复合人造木材产品由木纤维,聚乙烯基质和发泡剂制成。 将混合物通过形成所需产品轮廓的成型模挤出。 吸热发泡剂在挤出型材的中心引起更大的膨胀,并且在挤出型材的外边缘增加密度。
