优质的显象管离不开优质的水。当荧光沉屏溶液中混入了极微量杂质时,就会使它发生变色、影响其亮度;若高纯水中细菌数超标、将导致荧光沉屏出现划痕现象,就影响显象管的质量。现在国内一些显象管厂多数缺乏精密的细菌过滤设备。即使有,购价也比较昂贵,而过滤器免不了得经常换新的。若经常拆洗高纯水的输送管道,太麻烦又对连续生产不利。实践证明,用表面活性剂确实是解决沉屏时出现划痕现象的可行途径之一。
High-quality tube can not be separated from quality water. Fluorescent sediment solution mixed with a trace amount of impurities, it will make it discolored, affecting its brightness; if the high number of bacteria in the ultra-pure water, will lead to the phenomenon of scratching the fluorescent screen, it affects the quality of the picture tube. Now some of the majority of CRT plant lack of sophisticated bacterial filtration equipment. Even if there is, the purchase price is also more expensive, but the filter will inevitably have to change frequently. If you often take apart and wash high purity water pipeline, too troublesome and continuous production of adverse. Practice has proved that the use of surfactants is indeed one of the possible ways to solve the phenomenon of scratches Shen screen.
