在荷兰玻壳应用的焙烧检验中,发现大量“膜不匀”废品,最高废品率为30.5％,严重影响了正常的生产流程。这种废品与日本玻壳产生的废品不同。用小灯泡检查有机膜质量,发现不论是边缘区还是中心区都有位置不定,面积不同,形状各异的花斑、条纹等。为此,经反复试验、分析,此问题,终于得到解决,玻壳工程的合格率达80％以上。试验过程 1)从“温度”、“湿度”查“膜不匀”的原因在生产中,发现丙班“膜不匀”废品率最高。所以在夜班首先就严格控制沉屏间及涂膜
In the roasting test of the Dutch glass bulb application, a large amount of “film nonuniform” was found with the highest reject rate of 30.5%, seriously affecting the normal production process. This waste is different from the waste produced by Japanese glass bulb. Check the quality of the organic film with a small bulb, found that both the marginal zone or the central area has a variable position, different sizes, different shapes of the piebald, stripes and so on. To this end, after repeated tests and analysis, this problem has finally been resolved, the pass rate of glass bulb engineering more than 80%. Test process 1) From the “temperature”, “humidity” check “uneven film” reasons in the production, C class found “film uneven” the highest rejection rate. So in the first night on the strict control of the Shen screen and coating
