生漆和漆酚电阻率的初步研究

高绝缘性能材料,特别是液态高绝缘性能材料的电阻率,用一般方法较难测定。作者据漏电法原理,对我国重要的林特产品和出口商品生漆及漆酚的电阻率进行了测定,得到了生漆和漆酚的电阻率的数据。证明漆酚有很高的电阻率,是生漆电阻率高绝缘性能好的主要原因。漆酚是一种很好的液态绝缘材料。

A PRELIMINARY STUDY OF THE RESISTIVITY IN RAW LACQUER AND LACQUER PHENEL

It is very difficult to measure the resistivity of high dielectrics with dielectric lacquer liquid in particular by the general method. Based on the principle of electric leakage, the author measured the resistivity of raw lacquer and lacquer phenol which are very important forest exporting products and gained the first-hand data about their resistivity. The data are enough to prove lacquer phenol to be a kind of material with very high resistivity which is the main cause that raw lacquer has high resistivity and good dielectric performances. Also, lacquer phenol is a kind of dielectric liquids.
