在显象管,示波管等电子束器件内一般涂复大面积的石墨作为导电层。用于电真空器件内的石墨,对其物理、化学性能有特定的要求。特别对它的电气、真空性能的要求更为严格。目前,国内有不少厂家引进日本显象管生产线,用国产内石墨代替日本内石墨是各厂急需解决的问题。因此,国产内石墨的质量和性能能否达到或超过日本内石墨为大家共同所关心。 根据理化分析的结果(见表1),国产石墨乳在主要技术指标上,与日本石墨乳接
In the CRT, CRT and other electron beam devices generally coated with a large area of graphite as a conductive layer. Graphite for electrical vacuum devices, the physical and chemical properties have specific requirements. In particular, its electrical, vacuum performance requirements more stringent. At present, there are quite a few domestic manufacturers to introduce the production line of Japanese kinescopes, and replace domestic graphite with domestic-made graphite in order to solve the problems which the factories urgently need to solve. Therefore, the quality and performance of domestic graphite can meet or exceed the common concern of all of Japan graphite. According to the results of physical and chemical analysis (see Table 1), domestic graphite milk on the main technical indicators, and Japan’s graphite emulsion
