This invention discloses a method for preparing amorphous Cu-MOFs and their applications, relating to the field of metal-organic framework materials technology. The key technical points are: CuCl2 is used as the copper source and 4,4′-bipyridine as the ligand, and Cu-MOFs are synthesized via a solvothermal method. Transmission electron microscopy shows that the obtained material exhibits a typical micron-scale sheet-like morphology. After etching with ammonia, the sample morphology transforms into rough-surfaced nanospheres with a significantly increased pore size, indicating a local rearrangement of its framework structure. X-ray diffraction analysis shows that the original Cu-MOF has high crystallinity, while the diffraction peaks of the etched aCu-MOF essentially disappear, exhibiting amorphous characteristics. As a signal conversion element in a colorimetric sensor, aCu-MOF can achieve reliable detection of ampicillin under neutral conditions. Using thiram as a cofactor, a highly selective thiram colorimetric sensing system can be constructed.

This invention provides a method for quickly identifying the cause of abnormalities that occur during the spray application of amorphous refractory materials. [Solution] Multiple state quantities related to the spraying of amorphous refractory materials are detected from multiple sensors, and when an abnormal value is detected among the values ​​obtained from the multiple sensors, the cause of the abnormal value is identified. To this end, a correspondence relationship is created in advance between the cause of the abnormal value and the detected values ​​of other state quantities excluding the state quantity detected as the abnormal value, and when an abnormal value is detected among the values ​​obtained from the multiple sensors, the cause of the abnormal value is identified based on the correspondence relationship.
