PVC交通标志塑板的研究和开发

目前我国道路交通标志牌使用板材大都是铝合金，由于铝合金板属于不可再生资源，随着资源逐年递减而成本逐年增加。同时。由于铝材具有一定的回收利用价值。易引发交通标志牌被盗、破坏等维护管理问题。探讨采用新材料取代现有道路交通标志牌用材。以解决交通标志牌材料价格上涨和交通标志牌维护问题，达到节约资源。保护环境．降低成本的目的。

Research and Development of PVC Plastic Traffic Signs

At present, aluminum alloy, which belongs to non-rebirth resources, is mostly used as board materials of traffic signs in China. The cost increased with the yearly reduction of this resource. At the same time, some management problems frequently occurred on stealing and damage of the traffic signs because the aluminum materials used for traffic signs can be recycled and reused .Close attention is to be drawn to search new kinds of materials used as a substitute for aluminum alloy of traffic signs to decrease the cost and save the resource and protect the environment.
