我国在射线探伤中采用的增感屏有两种:金属箔增感屏和萤光增感屏。前者增感速度较慢,但底片呈像清晰,探伤灵敏度高,后者增感速度快,但底片呈像清晰度较差,探伤灵敏度低.随着我国工业生产的迅速发展,要求探伤的产品日益增加.因此提高射线探伤劳动生产率,保证射线探伤质量,扩大设备探伤能力对于满足探伤产品日益增加的需要具有一定的意义.
There are two types of sensitization screens used in China in the field of radiofrequency detection: the metal foil sensitization screen and the fluorescent sensitization screen. The former sensitization slower, but the negative film was as clear, high detection sensitivity, the latter sensory speed, but the negative film showed poor resolution, low detection sensitivity.With the rapid development of industrial production in China, requiring testing of the product So increasing the labor productivity of ray inspection, ensuring the quality of ray inspection and expanding the capacity of equipment inspection have a certain significance for meeting the increasing need of testing products.
