化工部晨光化工研究院一分院研究成功的硬 PVC 挤出结构泡沫新工艺,系采用高速高温混合新工艺和国内树脂粉料,由普通的单螺杆挤出机可直接挤出 PVC 结构泡沫和硬 PVC 异型材产品,而且产品性能优异。该工艺和传统工艺相比,其工艺流程短、不需造粒、节省人力1/3、生产周期缩短2/5～1/4、节约设备投资1/4。该课题已于
The new process of hard PVC extrusion structural foam researched by the branch of Chenguang Research Institute of Chemical Industry Department of Chemical Industry Department adopts high-speed high-temperature mixing new technology and domestic resin powder, and can be directly extruded from ordinary single-screw extruder PVC structural foam and hard PVC profile products, and excellent product performance. Compared with the traditional process, this process has a short process flow, does not require granulation, saves 1/3 manpower, shortens the production cycle by 2/5 to 1/4, and saves equipment investment by 1/4.
