摘要
水泥基复合夹芯墙板是一种新型保温隔热材料,其耐久性逐渐成为人们关注的重点。西部地区环境恶劣,温差大,紫外线辐射强,容易引起水泥基板开裂,开裂后容易造成水泥基板中的钢丝锈蚀,复合夹芯墙板里的钢丝锈蚀会加剧水泥基板开裂。此次试验采用C350电化学工作站,研究水泥基复合夹心墙板的极化曲线以及腐蚀电流密度,分析水泥基板开裂的原因,推动其在西部地区的应用。
Cement-based composite sandwich wallboard is a relatively new type of thermal insulation material, and its durability has gradually become a major concern. In west China, harsh environment, large temperature differences and strong ultraviolet radiation can easily cause cracks in the cement substrate. After cracking, it is more likely to cause corrosion of the steel wire in the cement substrate. The steel wire in the composite sandwich wall panel will cause the cement substrate to crack after the corrosion. In this test, a C350 electrochemical workstation was used to study the polarization curve and corrosion current density of the cement-based composite sandwich wallboard, and to analyze the cause of the cracking of the cement substrate, thereby promoting its development and application in west China.
