近几年来,由于塑料工业的发展,在工业与民用建筑工程中,采用塑料电管替代黑铁管进行电气布线的施工工艺,得到越来越广泛的应用。我公司为了保证电气安装质量,逐步推广应用塑料电管,对目前经常使用的塑料管进行调查分析,并作主要的物理和化学性能试验以资鉴别优劣,选择使用,现将调查及试验情况简述如下。一、塑料电管的基本性能和使用技术要
In recent years, due to the development of the plastics industry, in the industrial and civil construction projects, the use of plastic tubes instead of black iron pipes for electrical wiring construction process has been more and more widely used. In order to guarantee the quality of electrical installations, our company gradually promotes the use of plastic tubes, conducts investigations and analysis of the currently used plastic tubes, and conducts major physical and chemical performance tests to identify the advantages and disadvantages, and chooses to use them. We will now investigate and test the situation. Briefly stated below. First, the basic properties of plastic tubes and use of technology to
