钢塑复合生产工艺是对已加工好金属构件表面进行预处理,然后通过红外线加热箱对金属构件加热,保温至工艺温度(一般控制在230～350℃,以粉料的工艺温度为准)把加温到工艺温度的金属构件放入硫化床进行包复。再经过风冷或恒温使得金属结构件表面包裹一层0.5～1.2mm的塑料保护层,采用该工艺制成的钢塑复合构件包复层比较厚,在使用过程中塑料保护层不易被破坏,具有优于热浸锌、喷塑进行防腐处理的金属构件,具有很好的防腐性能,值得市场大力推广使用。
Steel-plastic composite production process is to have been processed metal surface pretreatment, and then through the infrared heating box on the metal components, insulation to the process temperature (generally controlled at 230 ~ 350 ℃, the process temperature to powder prevail) to The metal components warmed to the process temperature are placed in a sulfurized bed for cladding. After air-cooling or constant temperature, the surface of the metal structure is covered with a layer of 0.5-1.2mm plastic protective layer. The composite layer of the steel-plastic composite component made by the process is relatively thick, and the plastic protective layer is not easily damaged during use. With better than hot-dip zinc, spray for corrosion protection of metal components, has good corrosion resistance, it is worth promoting the use of the market.
