目前,在显象管生产过程中,蒸镀一层光滑平整、敷着牢固、厚度适当的铝膜已成为不可缺少的一环,它对提高屏幕亮度、图象对比度和延长荧光粉使用寿命有很大益处。因此,生产厂家和使用厂家愈来愈重视铝膜质量。我厂自85年8月进行第二次技术改造后,铝膜质量曾一度影响正常生产,其现象为铝膜破裂和大鼓泡(以下简称爆铝),一般认为小鼓泡的产生是不可避免的,但爆铝却对显象管的质量有很大影响。我厂因爆铝而造成焙检合格率下降15％,成品率下降5％左右。为此,对该问题进行了观察、试验与探索,在有机膜工序和蒸铝工序上采取了必要措施,取得明显效果。
At present, in the kinescope production process, the deposition of a smooth layer of smooth, well-coated, the thickness of the appropriate aluminum film has become an indispensable part of it to improve the screen brightness, image contrast and extend the life of the phosphor Great benefit. Therefore, manufacturers and manufacturers use more and more attention to the quality of aluminum film. After the second technological innovation in our factory from August 1985, the quality of aluminum film once affected the normal production. The phenomenon of aluminum film rupture and big bubbling (hereinafter referred to as aluminum burst) is generally considered to be inevitable. However, the quality of CRTs is greatly affected by the explosion of aluminum. I plant due to burst aluminum caused by baking pass rate of 15% decline, yield decreased by about 5%. To this end, the issue was observed, tested and explored in the organic film process and the steps on the aluminum to take the necessary measures to achieve significant results.
