酸碱环境及表面划痕对电缆防蚁护层有效性影响试验
Experiment on Effect of Acid or Alkali Environment and Surface Scratch on Validity of Cabled Anti-termite Sheath
摘要
Abstract
Guangzhou is a place prone to termite harmness,so buried cables mostly adopt physical anti-termite cables extruded by termigon sheath and the outer sheath materials.In order to study effect of acid or alkali environment and surface scratch on performance of the anti-termite sheath,colony test method was used for termite experiment after acid or alkali aging treatment for three months and six months for the test sample of termigon sheath.Experimental results indicate decay level of the new cable test sample is grade two,acid or alkali aging can improve anti-termite performance of the anti-termite sheath in short term and improvement effect of alkali environment is superior to that of acid environment.In addition,decay depth of the domestic termigon sheath is obviously deeper than that of the imported termigon sheath,but according to cur-rent evaluation standard,decay level of both two kinds of sheaths is grade two.It is suggested to detail evaluation grade of termite decay which takes decay depth as the core index and quantify decay area index.关键词
