Processing technology for improving warping defect of plastic building formwork
The invention discloses a processing technology for improving the warping defect of a plastic building formwork, and relates to the technical field of plastic formwork processing. The specific technology comprises the steps of 1) preparing silicon dioxide nanospheres; 2) carrying out ball milling treatment on copper powder; 3) processing to obtain porous metal powder; and 4) kneading and granulating a PC plastic raw material, uniformly mixing the PC raw material and the porous metal powder, adding a mixture into an injection molding machine, carrying out injection molding on obtained plastic melt into a mold, covering the surface of the mold with a layer of mica heat insulation plate after the injection molding is finished, and cooling and solidifying to obtain the required plastic formwork. According to the process method provided by the invention, the shrinkage difference of the plastic formwork can be effectively reduced, and the warping amount of the plastic formwork is reduced, sothat the warping defect in the forming process of the plastic formwork is reduced, and the forming quality of the plastic formwork is improved.
本发明公开了一种改善塑料建筑模板翘曲缺陷的加工工艺，涉及塑料模板加工技术领域，具体工艺如下：1）制备二氧化硅纳米球；2）铜粉进行球磨处理；3）加工制得多孔金属粉末；4）将PC塑料原料捏合造粒，然后与多孔金属粉末混匀后加入到注塑机中，将得到的塑料熔体注塑到模具中，待注塑结束后，在模具表面覆盖一层云母隔热板，待其冷却、凝固后即可得到所需的塑料模板。本发明提供的工艺方法，可以有效的降低塑料模板的收缩差别，实现塑料模板翘曲量的降低，从而减少塑料模板成型过程中翘曲缺陷的产生，使得塑料模板的成型质量得以提升。
