低温液氧容器使用水基型着色探伤剂灵敏度较低 ,不能满足要求。因此 ,在探伤工艺中采用加温、降温的温差法 ,可提高探伤灵敏度
Low-temperature liquid oxygen container using water-based color detection agent sensitivity is low, can not meet the requirements. Therefore, the detection process used in heating and cooling temperature difference method, can improve the detection sensitivity
