1、什么是聚合物发泡材料？
1. What is polymer foam?
由聚合物和气体分子构成的气固两相复合材料，气泡可以是分散相，聚合物是连续相，也是连续相，xps挤塑板是聚合物发泡材料的一种。井盖钢模具 U型槽模具 天津水处理设备 检查井钢模具 保定公司注册 u型槽模具 流水槽模具
For the gas-solid two-phase composite composed of polymer and gas molecules, the bubble can be dispersed phase, and the polymer is continuous phase. XPS extruded plate is a kind of polymer foaming material.
2、聚合发泡材料分类？
2. Classification of polymeric foaming materials?
可分高、中、低密度，也可分开、闭孔，也可分硬、软，也可分物理发泡、化学发泡或自由发泡，结构发泡，也可分热塑性材料和热固性发泡材料。
It can be divided into high, medium and low density, separated and closed cell, hard and soft, physical foaming, chemical foaming or free foaming, structural foaming, thermoplastic materials and thermosetting foaming materials.
3、聚合物发泡材料的成形方法有哪些？
3. What are the forming methods of polymer foaming materials?
目前的方法有挤出、注塑、吹塑、滚塑等。挤压生产效率高，占比最大。注塑主要生产高密度的材料，吹塑和滚塑所占比例较小。
The current methods include extrusion, injection molding, blow molding, rotational molding and so on. Extrusion has high production efficiency and accounts for the largest proportion. Injection molding mainly produces high-density materials, and blow molding and roll molding account for a small proportion.
